Abstract
Background: Antenatal classes orientation to increase knowledge, attitudes and practices of pregnant women in prevention of complications and antenatal visits. It-s performance was measured through input-process-output indicators. Process indicators are important because measuring its implementation which leads to meeting the needs and satisfaction of mothers. The low participation in antenatal classes was the effect of not optimizing process, both from dimensions of facilitators, participants and implementation. Purpose: The study purpose was explaining antenatal classes performance based on the success indicators of process from mothers perspective. Methods: A qualitative research exploring performance of antenatal classes from the success indicators of process. The main informants as many as 8 pregnant women participants of antenatal class were selected by snow-ball sampling from 5 PHC in Semarang city. Testing of validity and reliability with source triangulation. Data was collected by indepth-interviews and analyzed by content analysis. Results: The implementation of antenatal classes did not meet mothers expectation who are participants. In facilitator dimensions, conventional learning with face-to-face methods were felt to be ancient, monotonous, less interesting and boring. Communication and interactions were one-way and some information received even frightening some mothers. The tools used were simple and inattractive. In participant dimension, frequency of attendance was lacking because busy with housework and generally classes take place in the morning. Intensity of discussion was lacking because all materials already exists in MCH Handbook and could be read at home. Barriers to implementation dimension especially at the timing of activities that were not in accordance with time availability of mothers. Conclusion: Implementation time, perceptions and methods were obstacles to performance process. Continuous socialization, improving the ability of positive communication techniques and strengthening networks become the solving strategies. Need to development of comprehensive and creative health education model.

Abstract
Background: Immunization is the basic right for children to provide immunity to babies and children avoiding certain diseases. Immunization was optimally beneficial when given complete within the specified time period. The facts showed many parents do not immunize their children on schedule and tend delayed. The indicators of immunization program also only emphasize completeness rather than on timeliness immunization. Purpose: The study objectives was analysing the timeliness of complete basic immunization for children aged 12 to 23 months. Methods: An observational study with mix-method design and cross-sectional approach. Population are all children aged 12-23 months in Semarang City, and sample of 689 children randomly determined from all PHC. Information about reasoning for incomplete and inaccurate immunization was carried out by in-depth interviews with six mothers as key informants. Immunization status was obtained from MCH Handbook. Result: As many as 98.25% children have received basic immunization, although not all complete. Measles immunization was the most immunization that has not been received by children (13.35%), followed Polio-4 (8.27%) and DPT / HB / HiB-3 (7.4%). Immunization of HB-0 was a most timely immunization given (96.28%), followed by DPT / HB / HiB-3 (90.13%) and Polio-4 (85.44%). Measles immunization was the least timely (56.96%), followed by BCG (38.50%). Parents consider late immunization was no matter compared to not immunization. The source of information about immunization was generally obtained from health workers and cadres. Conclusion: Factors of understanding and socio-cultural were related to practicing of children immunization.

Abstract
Background: Maternal and Children Health (MCH) Handbook contained various information related to maternal and child health since pregnancy until toddlers. One of the information recorded are child immunization. However, MCH Handbook rarely used as the information sources for mother even though it has been given to all of the mothers in their early pregnancy. Purpose: The study objectives was analyzing utilization of maternal and children health handbook as information sources related to immunization in Temanggung District. Methods: A descriptive observational study with cross-sectional approach. Population are all mothers of children aged 12-23 months old, and sample were 520 mothers selected by cluster sampling based on PHC. Inclusion criteria were mother-s who have the MCH Handbook. Result: The main information sources related to immunization obtained from health care worker (93.7%) and health cadres (69.8%). There were 95.4% mothers able to show their MCH Handbook however, there were 93.8 mothers which keep the book by themselves. Only 68.3% mothers read the information in the MCH Handbook. However, they only read about the immunization schedule. Others important information related to immunization were unread. Most of mothers only understand that immunization are good for their children health. Conclusion: Utilization of MCH Handbook as an information source for mother of children aged 12-23 months old not optimal. It is needed to optimized cadres and health care workers role to socializing benefit of MCH Handbook as an information sources related to maternal and child health especially immunization.

Abstract
Background: Related to work productivity, the fitness level is one of the important conditions to be able to work optimally. On the other hand, based on an analysis of the daily activities of ITB lecturers and staff, in general they lack physical activity. Such conditions are of course very concerning because if you have low physical activity for a long time can have an impact on health, bad habits have the potential to make it easier to get degenerative diseases such as metabolic disorders, heart disease, cholesterol, diabetes and others. Purpose: On that basis, mapping the fitness level and physical activity of lecturers and staff in the ITB environment is very appropriate to be done as a first step in an effort to increase work productivity. Methods: Retrieval of data through the Rocport test, which is a test to measure the ability of aerobics by constantly walking as far as 1.6 km, then the output of this test will produce predictions of VO2Max ability. The sample in this activity are lecturers and staff aged 45 years and over. Results: From this study it can be described that ITB lecturers and staff are divided into several categories, namely the 0% thin category, 40% normal, 45% fat, 10% obesity. Then the condition of fitness with a very low category of 10%, low 16%, enough 23%, good 23%, very good 2%, superior 6%. In daily activities doing physical activity in the low intensity category is 36%, moderate is 34% and high is 30%. Conclusion: Physical activity with a low category has a tendency to fall into the normal and fat category, seen from the Body Mass Index. But because of the support of nutritional intake and good rest, the fitness level tend to be in the moderate and good category.

Abstract
Background: Adolescent sexual and reproductive health is best addressed through identifying their perceived needs, eradication of barriers to SRH services. This study aimed to assess married female adolescents (15-19 years) perceived needs for SRH service and barriers to utilization SRH services. Methods: The study was a cross-sectional survey of married female adolescents- (15-19 years) from six villages, three from Kurigram and other three from the Nilphamari district of northern Bangladesh. A total of 436 adolescents were selected randomly through multistage sampling completed a structured questionnaire with both open and close ended. This was supplemented with 10 in-depth interview. Univariate and Bivariate types of analysis have been applied. Results: Overall mean age of respondents is 17.85 years, mean age at first marriage of the respondent 15.26 years, 46.3% respondents have primary education and only 5.3% have education higher than secondary level. Over 75.2% respondents reported about having sexual and reproductive health related problems. 65.8% identified that they have knowledge about the components of SRH services. However only 37.2% perceived needs for the components of SRH services. Some barriers are responsible for non-utilization of SRH services such as: Personal, Socio cultural, Religious, Familial, Financial and Structural. There was difference among respondents of various age group, educational status and income groups regarding barriers to SRH service utilization. In-depth interviews also suggested similar situation. Conclusion: Respondents have knowledge about SRH services, Perceived needs for SRH services was very high in the study area. Yet due to victimize by several barriers they are unable to receive SRH services. In Bangladesh though SRH services are mainly designed for married women but most of the married female adolescents- (15-19 years) especially those who are residents of rural areas are vulnerable to utilize SRH services owing to numerous barriers, which requires urgent policy attention.

Abstract
Background: Bangladesh has been declared as the sixth worst affected country to climate change. This paper aims to identify life after migration of the respondents receding in a slum of Dhaka city, to identify the perception of migrants regarding climate change, to identify the perception of migrants regarding health and disease, to find out the health care seeking behavior of the migrants vulnerable to climate change. Methods: The study was a cross-sectional survey of climate vulnerable migrants who are receding a slum of Dhaka city. A total of 250 climate vulnerable migrants consist of 150 male and 150 female respondents were selected randomly and interviewed through a structured questionnaire. Univariate and Bivariate types of analysis have been applied. Results: The study indicates that after being victim of climate change respondents migrated to Dhaka city for a better livelihood but their socio economic condition collapsed in Dhaka city. Only 25.6% having permanent residence in current place, 90% lost their business and turned into rickshaw puller.Sin disease, Asthma and Respiratory Allergy were the three disease they suffered most, Climate induced diseases and after migration disease continuation rate is higher among male migrants compared to female. 50.3% female respondents perceived the idea of weather change. Though female perceived a better understanding about the changing weather pattern but their health care seeking behavior after migration deteriorated almost 53.3% don-t seek any health care, their attitudes as well as existing barriers of the new settlement basically keep them aloof from seeking the health care services. Conclusion: Increasing recurrence of climatic events, socio-economic losses, severity of environmental degradation and frequency of climate induced diseases push people in such a vulnerable situation that compel them to choose migration as an adaptive mechanism of climate change. Most of people these climate vulnerable migrants find their accommodation in the slums of Dhaka city that left them in a miserable condition where the terror goes but the agony persists. Thus the study highlighted that overall health care seeking behavior of the climate vulnerable migrants deteriorated after migration which requires proper attention in order to alleviate their sufferings in the slum area.

Abstract
Background: Multimorbidity among elderly is a major public health problem in most of the developing countries including Bangladesh where the population is moving towards aging. Little is known about multimorbidity in Bangladesh. The aim of the study was to identify the determinants of multimorbidity. Methods: A cross-sectional study was conducted in two tertiary level hospitals in Bangladesh with a sample of 572 adult-s age 60 years and older. The presence of chronic conditions was collected from medical examination reports at the hospital and data on socio-demographic factors was collected using structured questionnaire through an in-person interview. Multimorbidity was defined as the co-occurrence of at least two chronic diseases in one person whether as a coincidence or not.Age, sex, body mass index (BMI), marital status, place of residence, educational level, occupation, economic dependence, smoking, have been hypothesized as potential determinants for multimorbidity.Chi-square test, t-test, multiple linear regression, and multivariable logistic regression models were used to assess the association and the determinants of multimorbidity with the predictor variables where appropriate. Result: The overall prevalence of multimorbidity among elderly was 56.5% and the prevalence was higher among females (64.18 %) than males (54.17 %). The most prevalent conditions were hypertension (33%), diabetes (27.6%), ischaemic heart disease (12.0%), and chronic obstructive pulmonary disease (9%). The risk of multimorbidity increased with the increasing of age (OR: 1.03, CI: 1.04-1.06). Patients from rural areas (OR: 3.25, CI: 2.08-5.06), and economically dependent (OR: 3.82, CI: 2.38-6.13) had a higher risk of having multimorbidity than the patients from urban, not economically dependent patients, respectively. Conclusion: The study suggests that there is an urgent need to develop geriatric health care services by gender, educational status, place of residence. Urgent policy initiatives are needed to address gender, educational status and place of residence specific multimorbidity of the countries with similar socio-eeconomic situation to reduce the burden of multi-morbidity.

Abstract
The decline quality of land of cocoa plantations mainly due to erosion by runoff. The application of the Zero Run-off system can reduce rill erosion by eliminating surface runoff. The study was conducted to get the dimensions and layout of the system of Zero Run-Off is effective in improving infiltration so there is no runoff. Dimensions of the system is designed using the water balance approach, where all runoff accommodated in the zero Run- off system then infiltrated. Surface runoff calculated by the method of the Soil Conservation Service (SCS). Potential rate of water inflow into the soil is a function of the saturated hydraulic conductivity of the soil and the surface area of the system. Soil hydraulic conductivity is determined by the falling head method. Dimensions of the system known through a simulation model based on the physical condition data of field using a dynamic model. The simulation results show that the dimensions of the system are required to enter the entire runoff into the ground in the form of infiltration is a function of rainfall, catchment area and the soil saturated hydraulic conductivity. Using this data, the dimensions and position of the systems zero run-off can be determined accurately. For the conditions of research sites, the whole wet surface area of the system at 5 x 106 mm2 per m2. With a broad measure of the volume of water present in the systems of 0 to 0.0000055 m3, so that the system depths of 1,000 mm, then there is no runoff occurs.

Abstract
Indonesia is vulnerable to natural disasters such as: earthquakes, tsunamis, volcanic eruptions, floods, landslides and droughts and forest fires. Geographically, Indonesia is also located on the equator, so this region has a tropical climate. During the rainy season when rainfall is high, this condition triggers tornadoes, floods and landslides. While in the dry season, and low rainfall occurs drought, forest and land fires. While in the transitional season, the natural phenomenon of tornadoes is a threat of disaster. In Law No. 24 of 2007 of the Republic of Indonesia concerning Disaster Management, it is stated that the central government and regional governments are responsible for implementing disaster management, with an emphasis on preparedness and mitigation in the face of natural disasters. However, socialization to the community regarding the two matters is not regulated in the existing law, so that the planning and implementation of the outreach and internalization program must be carried out to the wider community so that natural disaster preparedness and mitigation can be carried out to the maximum. In line with the development of information technology and systems that have entered the era of media convergence, namely the integration of various technology platforms on one media or equipment owned by all levels of society, the acceleration of the process of disseminating preparedness and mitigation can also be done by utilizing these equipment. Using the theory of SECI Model, the development of knowledge management can be implemented to optimize the dissemination and development of data and information about sustainable mitigation activities related to natural disasters. The results of the research are in the form of developing a Knowledge Management System (KMS) for natural disaster preparedness and mitigation that can be used to support the socialization and internalization of disaster preparedness and community-based disaster mitigation activities, including dissemination and measurement of community preparedness and mitigation performance in the face of natural disasters.

Abstract
The development of the world internet usage continues to increase from time to time. It is recorded that 46% of the worlds population has become internet users and generates data traffic of 8 zettabytes every day. This increase has triggered the growth of data center infrastructure as processing, storage and communication system in the digital world. The data center itself has contributed 1.5% of total world electricity consumption and is expected to continue to increase. With the proportion of energy use in the data center, it covers 52% of electrical energy for information technology (IT) equipment, 38% for cooling and 10% for supporting equipment. One of the problems faced by data centers is the cooling of information technology (IT) components that are relatively large in energy, this has been a separate concern in several years of research. This paper describes cooling models that have the potential to improve the efficiency of using energy data centers. There have been many studies using several methods in order to find the most effective way to transfer heat data centers, one of them using the immersion cooling method. Immersion cooling promises energy efficiency improvements in the data center, using dielectric fluids that have high heat capacity. Several types of fluids and immersion cooling methods are identified and discussed in this paper.

Abstract
The aim of this research is to analyze the effect of using immersion cooling with different flow rate and fan rotation on decreasing the temperature on CPU. The study used three variables of flow rate: 0.5, 1 and 1.5lpm. in addition, three other variables of fan rotation, 400, 600, and 800 rpm, were used as well.. Data collection was by means of benchmark software to load the CPU to work maximum and the logging software to record the temperature. The results show that the immersion cooling could potentially be utilized as the new and more effective cooling system. The most optimum variable to decrease the temperature was 1, 5 lpm with fan rotation at 800 rpm. It decreased the maximum temperature from 60 °C to 47 °C, a deviation of 13 °C lower compared to the conventional fan cooling system with air as a medium. The study established that the higher the flow rate and the fan rotation, the higher temperature can be decrease. Therefore, immersion cooling can be the solution to decrease the consumption of energy on IT sector on a bigger scale.

Abstract
Indonesia has the highest potential of geothermal energy in the world with 30 GW. However, the utilization ratio is low with around 5% only. This situation occur since there are several geothermal energy targets failed to be achieved. The development of geothermal energy have several problems and one of them is rejection in the community when geothermal development begins. To overcome this situation, an increase in community understanding of this technology usage needs to be conducted. Therefore, the objective of this study is to discover public understanding by exploring the knowledge of vocational high school students about geothermal energy. This is conducted because they are young people who are part of the community. Their knowledge plays an important role in selecting energy sources for the country in the future. This study uses a triangulation strategy model that combines quantitative and qualitative methods. Respondents were students in Indonesia with a case study in Karanganyar Regency, Central of Java. Knowledge is measured by an indicator of the level of understanding of geothermal technology.

Abstract
This study is to compare the performance of synthetic refrigerants with hydrocarbons with variations in heat in residential AC units. The test method used is an experiment. Testing using split AC residential 1 HP. Paramter is tested, namely: effective energy ratio (EER), coefficient of performance (CoP), refrigeration effect (RE), amount of refrigerant flowing, pressure, temperature, and electricity consumption. The results showed that in general the performance of R-1270 is better than synthetic refrigerants. The EER, CoP, and RE R-1270 are greater than synthetic refrigerants. This value indicates that the R-1270 has a greater performance. The amount of refrigerant flowing, pressure, and energy consumption of electricity R-1270 are smaller than synthetic refrigerants. The data shows that R-1270 is more efficient than synthetic refrigerants. The lowest temperature that can be achieved by R-1270 is 1-2 oC higher than synthetic refrigerant. The difference does not have a big effect on the room to be conditioned. Comparison of performance with R-290 hydrocarbon refrigerants, R-1270 performance is still slightly below the performance of R-290. The difference is because the material used by the two hydrocarbons is different. The conclusion of this study is that R-1270 and R-290 are more effective and efficient for use in residential air conditioners. Technically R-1270 and R-290 can replace (retrofit) R-22 and R-32 in residential AC systems.

Abstract
Electric Vehicle (EV) is one of the technologies in the transportation sector that can reduce the amount of emissions. However, EV still faces some difficulties in terms of implementation. its application in several countries is still far from competing with Internal Combustion Engine (ICE) vehicles. Public acceptance of EV is considered as one of the obstacles. Therefore, this study will examine public perceptions of price, performance, and infrastructure and acceptance of this technology. Furthermore, an incentive policy that can be applied is also offered to respondents. The survey method with a quantitative approach is carried out in Indonesia with a population of Surakarta City residents. The results of this study can contribute as a reference for policy makers in drafting energy and transportation policies and as a discussion material for EV companies in their development.

Abstract
Development of metropolitan area in eastern Indonesia was established in 2003 which is regulated in Regional Regulation No.10 of 2003, concerning the Spatial Plan of the Mamminasata Metropolitan Area. Two years later the central government issued a policy about eastern Indonesia metropolitan which is regulated in Government Regulation No.7 of 2005. Six years later, the government issued a policy to establish a metropolitan region of eastern Indonesia as one of the national strategic area appropriate with Presidential Decree No. 55 of 2011. This study is focused on analyzing development policies in the metropolitan area in eastern Indonesia and their impact on urban governance. Descriptive research method with a practical approach is used to process data obtained from interviews and observations, reinforced by the study of secondary data from previous research results, as well as data from related institutions. The results of the study indicate that the metropolitan area policy seen from the institutional approach, functional process approach, and citizen participation approach, has not been able to be implemented properly. There is overlapping of authority between organizations that play a role in managing the development of metropolitan areas causing constraints on some developments. The lack of community participation in policy formulation has led to a reaction from some groups against the implementation of metropolitan area development in Eastern Indonesia.

Abstract
One of the causes of climate change is the use of fossil fuels. therefore, this triggers efforts to use renewable energy as a substitute fuel. According to REN21 data The development of renewable energy has declined from 2011-2016 along with the worlds energy needs. This issue is triggered, one of which is the policymaking of budget policies from several countries in the world, including in Indonesia. In this context, policy and government are the main components of implementing renewable energy. Therefore, the governments attitude towards renewable energy plays an important role in the success of developing renewable energy. We conducted a survey to explore the attitude of the local government to the potential of renewable energy in Indonesia which has the potential to vary from each region. One area may have more renewable energy potential than the other. The results of this quantitative study are expected to help national policies on the development of renewable energy not only in Indonesia, but also in other countries where the diversity of opportunities spread throughout the region.

Abstract
In response to the diminishing availability of fossil energy sources, many countries have increased the use of renewable energy, especially wind energy. The application of wind turbines is often in conflict with landowners/users, especially the tourism sector, which is one of the emerging industries throughout the world including Indonesia. Whereas, most tourists who travel in Indonesia aim to enjoy natural beauty. This study analyzes the attitudes of tourists on the application of wind turbines in coastal tourism objects, by comparing how the visual impact in the installation of wind turbines whose different levels of beauty will affect their attitude. Quantitative methods through questionnaires and. Sampling with simple random sampling technique is used in this study. The results show that tourists will tend not to visit coastal attractions if there are wind turbine installations. They argue that wind turbines threaten the nature of the tourism industry.

Abstract
The Government of Indonesia through Vision Energy 25/25 saves energy by saving fossil fuels. One sector that consume the largest fossil fuel is transportation. Through the vision, this sector has a great opportunity to make savings by converting fossil fuels into biofuels as stipulated in the mandatory B20 policy. The success of the implementation of the policies depends on providing socialization to the public. Therefore, the objective of this study is to collect the information about the level of knowledge of the community in receiving information about the use of biofuels in the transportation sector. This is a quantitative study using a questionnaire in data collection, finding that peoples understanding of biofuels, including the perception and information of biofuels, still needs to be improved. The results of the research can be used to assist in the planning, implementation and evaluation of policies made in the use of biofuels in the transportation sector in Indonesia.

Abstract
The film is a product of mass media that elevates the cultural and social values in society. Women in social construction are always portrayed feminine, as in Disney animated films. However, since the early 2010s, Disney animated films shift their image of women. Women in Disney used to be portrayed in a subordinated, dependent and passive position have now turned into an independent, capable, active and not necessarily need men, such as Brave and Moana. The concept of Gender and Media in this study aims to see how the media constructs women. The theory used is Sigmund Freud identification theory which discusses how to construct and establish gender subjectivity and map gender with Mulvey Gender Concept. This is qualitative research with Chris Mertz semiotics to show signs in films and Charles Sanders Piere semiotics in interpreting data. The paradigm in this study is constructivist, to explain how meaning is being formed. The results of this study construct women to be the main characters in the films Brave (Merida) and Moana (Moana) which lead to masculine characteristics. Like being strong, independent, active, rational, intelligent and not always related to romance. Suggestions from this study are expected to be a reference for gender studies and provide awareness about being women in this era.

Abstract
The behavioristic learning flow defines where knowledge must be built or influenced by social and cultural developments. (Brooks & Brooks, 1993),further (Jenkins, 2000, p. 601), thus constructivism views learning as a change in behavior as a result of interactions between stimulus and response. Cooperative Learning is one of the best choices for all students, creating dynamic communication between students with different competencies and abilities (Ghaith, 2003) .This approach is believed to be able to improve student learning outcomes, improve social behavior, and affective maturity (Tsai, 1998). This study aims to produce design (syntax and Component) Cooperative Learning based learning on the baduy indigenous people outside The research method for designing the model consists of three stages theoritical study, exploration and design.The results of the study show that compatible model prototypes are applied and the syntax of informal learning-based learning models on indigenous peoples Baduy outside consists of stages (1) Opening (Habar Rereongan) (2) Pikukuh Rereongan (3) Gawe rereongan (4) Ice Breaking (entertainment rereongan) (5) Nagawadang Rereongan (6)Panen Rereongan.
