Abstract
Sunda Straits can be regarded as one of the waters that has a significant traffic density of vessels which serves national and international voyage. Based on data, about 53,068 ships sailed through the Strait in 2016. Because of the reason, a scenario of traffic separation scheme (TSS) is required to ensure safe shipping on the strait. Sunda strait is a one of the significant point of Indonesia first archipelagic sea lane passage (ALKI-1), therefore it very important for Indonesia to actively contribute to manage the strait to protect Indonesia interest such as : national security, voyage safety, marine protection and tourism. At the end of 2018, IMO agreed to adopt the TSS proposal on Sunda and Lombok strait provided by Indonesia in June 2019 by IMO Maritime Safety Committee (MSC). Consequently, Indonesia will actively manage the traffic for international purposes meanwhile protecting Indonesia interest. However, to imply the plan Indonesia need to provide a big commitment, such as; legal instrument, infrastructures and facilities that are need to well-maintain for 24/7. And the paper will present a deep analyse on the law of the sea aspect, regarding the beneficial for Indonesia and possible challenge that will arising on the future.

Abstract
Poverty is still a major problem in Indonesia. In an effort to overcome the problem of poverty, the government has tried to develop various programs that want to alleviate the poverty of its citizens. But not infrequently these programs do not go according to plan and cannot reach the goal. In contrast to these problems, the Kulon progo community has persistent leaders in fighting for the rights of their people. Integration of an independent economy was created, and only a few years of poverty in Kulon Progo were successfully obtained.

Abstract
Abstract The study aimed at identifying the existing rice storage facilities, problems and prospects at farmer-s level in some selected ten area in rural java Indonesia. The farmer-s suggested policy options for traditional seeds safe storage of rice are also discussed. The selection of traditional seeds and villages were done purposively whereas the traditional storage system using cooperative storage system were selected randomly using stratified random sampling technique with arbitrary allocation.The farmers were classified as small, medium and large based their land ownership. Data on the average rice production, consumption, storage volume and costs of storage and losses of rice in different storage using 10 varirites structures/containers from selected 10 farmers of study areas were collected through pre-tested questionnaire. The farmers generally used traditional seeds such as Dolah, Luweng Motka, Jala, Gandul, Margono, Rahayu, Dalem,Jaran, Kasturi for storing rice. This system are selected compare with conventional storage seeds system using genetic seedsUsing traditional seeds give economical benefit for the farmers considering the capital cost, expected life and storage loss. Over 90% of the farmers- felt the need for training on safe storage and over 80% of the small and medium farmers were interested in getting government help through loans, grants, etc. About 90% of the farmers expressed their satisfaction on traditional storage system to store and protect their traditional seeds during the post harvesting time. Farmers opined to construct traditional storage structures at an easily accessible place within their village and used traditional seeds under cooperative storage systems. The proposed traditional seeds storage system, on implementation, could be managed by using integrative or overseen by a committee elected/selected by the cooperative society members.

Abstract
Height measurement is one among other means to monitor the growth and development of children. Height measurement is carried out in various parts of the world for this purpose. This study wanted to find out how growth in height and neuro-muscular reaction time --NMRT of female students, especially in the Tengger Mountains area, Pasuruan; and the coastal area of Kenjeran, Surabaya. Both have different contrast environments. Measurements were made on 273 female students aged 10, 11, 12, and 13 years. Height was measured using a standardized anthropometer. The NMRT was measured using a ruler that is dropped suddenly and must be captured by the female students. t-tests was carried out on these measurements to determine whether they have significant differences. The results showed that there were significant differences in height at ages 11, 12, and 13 years. Significant differences in NMRT occurred at 12 and 13 years of age. We conclude that growth on female students in Tengger and Kenjeran differed significantly in height and NMRT, but the significance of these differences began at different ages. The NMRT differs more slowly. It is suspected that the quality of life in the Tengger Mountains area is not as good as the Kenjeran Coastal area, but it we need to study further.

Abstract
This study investigates the management of asset structures in Indonesian islamic bank. The study uses panel data from 10 Islamic banks in indonesia, covering the period 2010 to 2018. All significant data have been taken into account in analysing whether there is a relationship between asset structure management and certain factors involving bank-specific financial conditions and macroeconomic features. These include financing, deposits, profits, money supply and gross domestic product (GDP) The results reveal that asset management structure is significant for total financing, total deposits, money supply and GDP. In conclusion, the management of asset structures acts to efficiently prevent any unexpected crises that may affect banking operations. The structure of asset management in Islamic banking is influenced by internal and external factors which have the most impact on asset management by Islamic banks. Islamic banking also provides more financing to reduce their risk and at the same time they attempt to increase deposits and investment in due to interest rate volatility in conventional banking.

Abstract
In this study we explore the differences in work values of generation X and Y in The Ministry of State Secretariat as one of public institutions in Indonesia and find out the dominant work values from both generations. This research used a qualitative content analysis method with open ended questionnaire. Respondents of this research were 115 employees as representatives from 9 units, consisted of 58 generation X (50%) and 57 generation Y (50%). Work values dimensions of "Instrumental value", "cognitive value", "social value" and "prestige value" (Lyons, 2010) were most commonly found in the field. The result of this research also showed that mostly both generations performed instrumental work values meanwhile the least work value that were performed was prestige work value. The instrumental work value mostly performed by generation X with "supervisor" category (i.e.‘supportive supervisor-), and generation Y performed "training" category (i.e. ‘the opportunity for education and training-). Cognitive work with category "advancement" was dominant from both generations, especially for generation Y (i.e. ‘promotion-). The social work value with "co-worker" category was dominant from both generations, mostly generation Y (i.e. team work). Prestige work value with "impact" category (i.e. ‘involving in activities that support organizational performance-) was dominant from both generations, especially for generation X. Our result also suggest that differences in work values were strongly influenced by the culture, so the finding are different from those in several other countries.

Abstract
Women have little or no access to voice their experiences in the environmental protection and management. This situation is due to the deeply rooted patriarchal culture and poverty which makes women suffer a lot. The Indonesian environmental law is considered gender neutral. However, the government and law enforcement officers do not have an adequate gender perspective to fully interpret the law. Meanwhile, women have actively participated in maintaining the environment. Thus, the gender neutrality in the law is now questioned within the environmental law framework. This question is significant for those who are concerned on the gender neutrality in law which aims to achieve substantive equality. In this paper, I would like first to consider the gender equality principle in the Indonesian law in general and specifically in the Indonesian environmental law. Then, I would like to show that there is still a weak law and lack of will from the government and law enforcement officers to implement gender mainstreaming into environmental law. Furthermore, experiences from other ASEAN countries will be examined to enrich the translation of gender equality in the Indonesian environmental law. I, then analyze ASEAN regional mechanisms with the aim of enhancing the gender perspective in the Indonesian environmental law. I conclude that the strong gender perspective is needed in interpreting the Indonesian environmental law in order to achieve substantive equality.

Abstract
The number of adolescence pursue their education to senior high school and university level in Bandung regency is very low. Most parts of Bandung regency are belonging to rural area, which is remote from the densely populated area in a city. The number of senior high school and university is much less then Bandung city. In one of the area in Bandung regency, adolescence that do not continue their higher education become unemployed or working in informal area. This occur mostly not due to lack of academic ability or intrinsic motivation, but due to financial factors, as their parent-s income is often insufficient for their daily needs and further education available nearby. There are internal and external factors that can affect future orientation. One of the external factor is parents. Parents can have a very crucial impact on their children-s future orientation. Therefore, the present study investigated the influence of parent support on the motivation and interest of their children, especially in rural area such as Bandung regency. The method employed in the present study was regression study to measure the role of perceived parenting of father and mother on the future orientation of adolescence. The research subject was 93 students who attend 11th grade senior high school (37% male and 67% female), aged between 16 to 18 years old, which in agreement with grade 11 or adolescent period proposed by Santrock (2007), Newman & Newman (2015) and Steinberg (2014). Participants were asked to fill in 2 questionnaire, i.e. perceived parenting and future orientation questionnaire. The correlation analysis of the present study showed that the relationship between future orientation and perceived parenting is not significant (F-value 1.84, p-value = 0.17). Therefore we conclude that the perceived parenting is not significantly related with future orientation. According to Seginer, parenting is not directly related with future orientation, but related through the self, in this case the self is the adolescence.

Abstract
Many of the facilities for disabled students at many universities in Indonesia are considered not ready to accept them to study optimally. However, not being ready perfectly is no reason not to allow disabled students to study at universities. We examined the role of volunteer students in assisting with disable students so that they could learn better at the university level. We interviewed 5 volunteers at Airlangga Inclusive Learning Center. Data were collected using indepth interview. The volunteers accompanied the disabled students during lectures, seeking teaching materials in the library, as well as seeking teaching materials requested by their lecturers, became translators for deaf students, and became note takers for blind students. This study implemented a descriptive qualitative approach. The results of the study showed that volunteers who assist disabled students feel that they have useful new experiences. We found that student volunteers were able to carry out the various roles needed to support an inclusive campus. Some volunteer students were also able to act as facilitators who facilitated the disabled students outside of academic activities. Increasing the ability of student volunteers is very important so that they can expand social services within the campus environment, thereby increasing students social functioning to disabled students in the university environment.

Abstract
Telkomsel as a digital telecommunication company has released digital-based applications Virtual Assistant (VA) which is used to facilitate customers to make transactions and information channel. However, customers who have purchased through VA are very low compared to the total active VA users, so it needs to analyze how to increase purchasing via VA. The objective of this research is to provide an insight of customer characteristics by using prediction models based on historical data using behavioral segmentation (occasion, benefits sought, user status, usage rate, and loyalty status). Data is analyzed using random forest algorithm by using two models, per segment data and all segment data behavioral segmentation. Theoretical approaches that used are digital marketing, behavioral segmentation and customer behavior. Random forest analysis with a total of 22 input variables and 130,388 records resulting all segment data model produced the highest accuracy compare to per segment data model. All segment data produced accuracy 96% with 49,948 predicted customers and predictor importance variables such as loyalty point, recharge, data payload, SMS and Voice transaction. Those variables are used as recommendation for Telkomsel in marketing strategy to determine product/bonus/gimmick that will be offered to increase purchasing via VA.

Abstract
One of the factors that enhances peoples welfare is the existence of good licensing services so as to facilitate the community in the licensing process especially for business people and indirectly assist the economy. Therefore, the government issued an Online Single Submission (OSS) program, a system that integrates all business licensing services electronically for business actors in the form of business entities or individuals. Although its good to do, so far it hasnt been felt optimal. Even so, the One Single Submission (OSS) program is a government innovation that is feasible to continue to be developed because it provides many benefits for the community and encourages economic development so there needs to be an evaluation for this program so that it can provide appropriate facilities for the community, especially business people and stakeholders. This research method uses a variety of literature including books, previous research, news and other literature. Based on the results of the literature review found several factors that hinder the optimization of the program. The hope is that this article can trigger further research to analyze the Online Single Submission (OSS) program.

Abstract
Refractory coating is widely used in metal casting process to protect the mold from direct contact with molten metal. This coating also could improve the surface quality of casting product. Zircon is common materials that used as filler, but the materials cost is quite high. Therefore, alternative material is needed to make partial substitution of the filler. Silica Fused can be considered as filler because it has good refractoriness. This study aims to determine silica fused is reliable as an alternative to substitute zircon filler. The samples were made with 16%, 18%, and 20% silica fused addition and different treatment which were heated and non-heated drying. Particle size and distributions of the filler were analyzed using Particle Size Analysis. Viscosity measurement also has been done to analyze rheological characteristics of coating slurry. The surface morphology of dried coating was taken using Scanning Electrom Microscope. The quality of coating was determined from the thermal stability of the coating that was analyzed using Differential Thermal Analysis. The result shows thar silica fused is reliable as an alternative material for filler partial substitution.

Abstract
Rice is the main staple food in Indonesia that has the four largest population in the world. East Java is one of the largest rice producing centres in Indonesia and many other regions such as Papua, Kalimantan, NTT, Sumatra, DKI, and Yogyakarta depend on its supply of rice. The contribution of rice from East Java to other provinces is 17.1% and there is a decline every year while the consumption of rice is increasing every year. How the sustainability of the East Java rice supply in the future needs to be known to policyholders so that there will not be a crisis of rice shortages so that the understanding of Indonesian food becomes disturbed. The purpose of this paper is to develop a system dynamic (SD) model for estimation of East Javas rice contributions to Indonesian food security. An integrated system dynamics simulation model was developed using a system dynamics modelling approach to examine the interaction and feedback processes between the production per year, paddy planting area, consumption per year, agricultural production sub-sectors and population subsectors. The objective of the model is to provide a learning tool to understanding of the long-term dynamic behaviour of the rice production, and as a decision support tool for exploring plausible policy scenarios necessary to make East Java readiness on achieving the target as “Lumbung Padi Nasional”. Managing the agricultural development, providing the structural and behavioural pattern tests, and doing the statistical test to evaluate and validate the performance of the model. The results showed that the simulated outputs represent the real system. Three additional scenarios were simulated. (scenario 1) expanding rice field area, (scenario 2) improving the intensification and there should be additional support to farmers through provision of agricultural inputs such as seeds, fertilizers and pesticides and be given sufficient training to best apply these input and (Scenario 3) increasing the amount of infrastructure in order to distribute more supply.

Abstract
Conformity assessment is a process commonly used in calibration activities to ensure the validity of the results of measurements or calibrations with specific requirements or standards. In this research the use of conformity assessment was carried out on long gauge block calibration activities in National Metrology Institute of Indonesia by determining objective criteria called decision rule which aims to determine the limit of conformity assessment, conformance zone, and specification zone requested by the calibration customer. Decision rules are made by referred in statistical acceptance sampling based on go/no-go decisions with Gaussian Probability Density Function for the measured quantity. From this research, it was found that in the calibration process of long gauge block, the use of the decision rule concept was to use tolerance interval with a guard band. The guard band value is obtained from the uncertainty measurement analysis of the long gauge block calibration, while the acceptance zone value is obtained from the limit deviation of long gauge block based on ISO 3650.

Abstract
As it is known that the failure of the boiler pipe often occurs on the super heater pipe of a Steam Recovery Boiler Pipe Generator (HRSG). Super heater is a component where water vapor is heated with a temperature around 816 ° C to produce enough steam to drive a generator at a steam power plant. The purpose of this study is to analyze the failure of the super heater pipe of the HRSG which has broken. This research starts from visual observation of broken pipes. Further information is also sought about the operating conditions when the pipe breaks. Then a laboratory test was carried out to determine the chemical composition of the HRSG boiler pipe material. Moreover the hardness testing was conducted by using Rockwell Hardness Tester ZHR 4150AK/BK Zwick Roell. And then the micro-structure was observed by using Microscope Optic Olympus GX71. SEM (Scanning Electron Microscope) observation on the fracture surface was also conducted to find the initial crack. From the results of chemical composition testing, it was found that the material of super heater pipe is made of carbon steel materials ASME SA 178. Metallographic results show that the micro-structure of this material is Ferrite - Pearlite. The result of hardness test shows that the surface area of the pipe is not broken has an average hardness of 25.3 HRB and the hardness of the broken surface has an average hardness of about 15.4 HRB. From the SEM observation, it is known that the failure occurs in a ductile fracture due to inter granular crack occurs on on the fracture surface of the pipe. The presence of deformation (creep) seen on the super heater pipes is due to operating at high temperatures and pressures with long operating time. This condition causes the thickness of the pipe to be depleted and also the presence of pitting corrosion on the inside of the pipe so that it breaks due to crack propagation which penetrates the wall of the pipe until it breaks because the material is no longer able to withstand the steam pressure inside the pipe. To find the magnitude of the stress intensity factor around the tip of the crack is conducted using Finite Element Analysis. From the finite element analysis results, it was found that the stress intensity factor, KI is about 59.49 MPa√mm which occurred in the initial defect area was greater than the value of the fracture toughness of the material KIC is about 49.15 MPa√mm (KI > KIC). This condition indicates that the crack propagation occurred through the pipe wall which caused the boiler pipe to break.

Abstract
Cassava starch is one of the biopolymers which can be degraded to many useful products such as reducing sugar, non-reducing sugar and modified starch. However, it has a solid granule structure that can inhibit its degradation process. High shear mixing (HSM) is a well-known method for dissolving biopolymers. Shear effect of HSM created by narrow slit between rotor and stator which can be increased by the increase of rotational speed. By increasing its shear effect, HSM is able to cut the glycosidic bond of starch to produce reducing sugar. Therefore, this study aims to study the effect of high shear rate to granule structure and reducing sugar product. The HSM process was carried out on the suspension of cassava starch with concentration of 1/20 (g/mL) for 15 min at various stirring speeds (5000-15000 RPM). Products produced from the process are separated between solid and liquid for analysis. Solid products were analyzed using Scanning Electron Microscopy (SEM), Particle Size Analysis (PSA), and Viscometer Ubbelohde. While liquid products were analyzed using UV-Vis Spectrophotometry with the DNS method. Based on the experimental results, HSM produced reducing sugar up to 0.1972 mg/mL. Granule breakage was also observed by SEM and increasing of nanoscale granule.

Abstract
Uncontrolled hemorrhage is the leading cause of death. The efficient hemostatic dressings are needed to promote coagulation and hold ongoing hemorrhage. Hydrogels are hydrophilic polymers with three-dimensional network structures with high swelling capacity to prevent accumulation of exudates. Hydrogels prepared from polyvinyl alcohol (PVA) grafted with chitosan have attracted considerable attentions due to their biocompatibility, high moisture balance property, and transparency. This study utilized alginate to improve elasticity and thermal stability, also enhance hydrophilicity and increase swelling ability. The hydrogels composed of PVA (7.5 % w/v), chitosan (0.05 % w/v), and alginate (0.2, 0.4, and 0.6 % w/v) were synthesize by gamma irradiation technique at total dose of 15 kGy. The results showed that the increasing of alginate concentration in the total reactant mixture can improve elasticity, swelling capacity and the equilibrium degree of swelling (EDS), and decrease water vapour transmitted rate/moisture vapour transmitted rate (MVTR). The hydrogel wound dressing with 0.6 % of alginate concentration was the best product in this study with 79.49 % gel content, 608.65 % swelling ratio, 628.32 % EDS in 22 hours, elasticity 62,58 KPa, evaporation rate (MVTR) 105g/m2h, degraded at temperature of 298.89oC, and the weight loss was reached 88.84 % (w/w).

Abstract
One stochastic process that is often used to model real phenomena is the compound Poisson process (CPP). CPP is a process in which a component in the process of the events occurred is assumed to be a Poisson process with a certain intensity function (homogenous or nonhomogeneous). Thinning process algorithm is usually used to generate events that occurred in the Poisson process. The study aims to find out the algorithm for generating the CPP which has nonhomogeneous Poisson process (NHPP) intensity functions. The value of the load caused by the Poisson process is assumed to be a family of i.i.d random variables and the variables are also independent of the Poisson process. The results of this study have obtained the thinning process algorithm and its generalizations for compound Poisson process having nonhomogeneous Poisson process (NHPP) intensity functions. This algorithm is the result of developing theory and computational simulation analysis by generating data that can be applied in various fields of science.

Abstract
This research was conducted to discuss the application of risk-based thinking concept in calibration and testing laboratories. This research is motivated by the publication of the new edition of ISO/IEC 17025:2017 standard that applies the principle of risk-based thinking. From the results of the JCRB 39/3 resolution, full-implementation of ISO/IEC 17025:2017 standard by calibration and testing laboratories is no more than 3 years after publication. In addition, the National Accreditation Committee (KAN) as an accreditation body in Indonesia requires calibration laboratories and testing laboratories to switch their QMS to ISO/IEC 17025:2017 standard starting at 2018. This research is carried out by identifying the risks found in calibration and testing activity. Clause 8.5 of ISO/IEC 17025:2017 is applied to take actions to minimize or eliminate risks that have been identified as preventive or corrective actions. In this research, 5x5 risk matrix is also used by considering the impact and frequency of risks in the calibration and testing laboratories.

Abstract
Emotion is one of the advantages given by God to human beings compared to other living creatures. Emotions have an important role in human life. Many studies have been conducted to recognize human emotions using physiological measurements, one of which is Electroencephalograph (EEG). However, the previous researches have not discussed the types of wavelet families that have the best performance and canals that are optimal in the introduction of human emotions. In this paper, the power features of several types of wavelet families namely daubechies, symlets, and coiflets with the Correlation Feature Selection (CFS) method to select the best features of alpha, beta, gamma and tetha frequencies. According to the results, coiflet is a method of the wavelet family that has the best accuracy value in emotional recognition. The use of the CFS feature selection can improve the accuracy of the results from 81% to 93%, and the five most dominant channels in the power features of alpha and gamma band are T8, T7, C5, CP5, and TP7. Hence, it can be concluded that the temporal of the left brain is more dominant in the recognition of human emotions.

Abstract
Currently a new method of using taxis appears, that is the online taxi application. This new method is increasingly popular because users can order services only through applications on cellular phones, they can also choose motorbikes or car taxis, and estimate the price for the services. Since its appearance, many people have benefited from this online application, not only as users, but also as drivers. The public perception of the taxi drivers began to shift, which was mostly performed by men that is now also done by women. The purpose of this study was to determine the public perception of the female drivers of motorbikes or cars taxi using the Kano model. The Kano model is usually used to determine the specifications of a products features. In addition to knowing the features of a product, the Kano model can also be used to find out service features in the service industry. The dimensions used to define service features are Appearance, Main Skill, and Soft Skill. From these dimensions, 8 service features are obtained. The results of the study are expected to reveal peoples perceptions on female taxi drivers based on Must-Be, Performance, and Attractive categories.
