Abstract
Dayak onion (Eleutherine palmifolia) is a typical plant of Central Borneo, Indonesia. Dayak onion contains flavonoids, saponins, polyphenols, alkaloids, glycosides, steroids, phenolic, tannins, triterpenoids and quinones, and has bioactivity as an antioxidant. Extraction using the ultrasonic assisted extraction (UAE) method can increase phenol compounds and antioxidants in a shorter time. The purpose of this study was to determine the effect of variations in the amplitude and timing of sonication of purified water-based UAE to increase the value of antioxidant activity and the total value of phenol from Dayak onion powder extract. The amplitude variations used in this study were 20%, 35%, and 50%, and the variations of the sonication time used were 5, 10, and 15 minutes. Testing of antioxidant activity was using the DPPH (1,1-dyphenyl-2-picrylhydrazyl) method and total phenol content was tested by the Folin-Ciocalteu method. In the results of this study, the best value for antioxidant activity on Dayak onion powder extract was at a variation of 50% amplitude and 5-minute sonication time, which was 2.433 ± 0.283 mg / ml. While the best value on the test of total phenol of Dayak onion powder extract was at a variation of 35% amplitude and 5-minute sonication time, which was equal to 6.558 ± 1.68 mg GAE / g. Based on the results of ANOVA statistical analysis, it was found that there was a significant effect on antioxidant activity with a significant value of 0.048 on variations in the combination of amplitude and sonication time.

Abstract
Apple (Malus sylvestris L) is one of important crops cultivated as a raw material to produce typical product from Malang City such as, apple drink and chip. In order to produce a good quality product, a uniform ripeness level of apple need to be attained. As a traditional method, the farmer and industrial worker only sorted the raw material based on its physical properties, i.e. size and colour, which depend on their decision that may lead to non-standard result. Thus, to address this issue, a rapid and quantitative measurement such as UV/Vis spectroscopy need to be developed. The aim of this research is to study the feasibility on the use of UV/Vis spectroscopy to determine apple quality based on its chemical compound. To achieved the conclusion, several stages had to be conducted. First, the total 60 sample of apples from 4 different ripening stages (3, 4, 5 and 6 month) were collected from local farmer in Bumiaji District and extracted. The juice from extraction was prepared for UV/Vis spectrum collection ranging from 340-800nm. Then, the Total Phenolic Compound (TPC) and pH were measured. Second, performing chemometric analysis to provide Partial Least Square (PLS) prediction model. And the third was identifying robustness of the model by analysing all the statistic parameter. The result showed that, PLS model to predict pH provided good determination coefficient (r2) resulting 0.9142 while RPD, LV and RSMEP accounting for 1.98, 6, and 0.0466 respectively. Meanwhile, the TPC could not be predicted well by using this regression.

Abstract
In order to determine the ripening stages of apple (Malus sylvestris L), local farmer in Malang still utilized a traditional method by examining its size and appearance. However, this method needs worker-s extensive experience causing a non-standard ripeness level that may lead to lower the economic value of the crop. Thus, to strive this problem, fast and quantitative prediction method need to be developed. UV/Vis spectroscopy has shown its capability to provide a robust prediction of several internal attributes such as, Total Solube Solid (TSS) and water content. The aim of this research is to develop a Partial Least Square (PLS) regression to predict internal parameter contained in apple. Sixty sample of apples were taken from local plantation in Bumiaji district. There were 3 stages to complete the research: (1) spectral data acquisition ranging from wavelength 340nm-800nm; (2) Internal parameters measurement (TSS, water content and firmness); (3) Performing PLS regression based on spectral data and internal parameters. The result showed that PLS model of TSS could provide a good coefficient of determination (r2 = 0,80) and for RPD, LV and RSMEP resulting 1.92, 7, 0.90 respectively. On the other hand, the model could not predict both water content and firmness; the model only provided low r2 accounting for 0.73 and 0.53 respectively. Further enhancement need to be addressed to the model for improving its capability of apple-s quality prediction.

Abstract
The development of a city depends on how easily the area can be accessed. The role of the government to provide facilities and infrastructure as a facility to meet community needs is a responsibility. The Tangerang City Government is one of the cities that has implemented BRT policy as public transportation since December 2016. Based on the monthly report, the number of BRT passengers has a tendency to decrease the number of passengers. This study aims to assess and analyze of BRT Trans Kota Tangerang service performance. The study uses quantitative methods, based on 5 dimensions of servqual, namely Tangible, Reliability, Responsiveness, Assurance and Emphaty, then assessed as referring to the standards of public transport services SK Dirjen no.687 of 2002, Minister of Transportation Regulation no. 10 of 2012, amendment no. 27 of 2015, ITDP 2016 BRT Standard. The purpose of this study was to analyze the level of importance and level of satisfaction of users towards the perceived performance of BRT Trans Kota Tangerang service. The service is assessed from the perceptions and expectations of BRT users. The results of the study show that the level of importance that must be prioritized is the tangible dimension of the item information on the stop service to be passed in the form of visual / audio in the stop functioning properly. BRT users are dominated by middle-class (captive) economic people who have no choice and depend on public transportation for daily mobility. This has an effect on the results of the satisfaction level of BRT users who compare with other public transportation. So that BRT users were very satisfied with BRT Trans Kota Tangerang service performance.

Abstract
Betaine as metabolic enhancer is proven to improve eggs production in poultry. The consistency of the improvement, however, is not yet explored. This study aimed to explore the consistency of quails- egg production under the influence of betaine supplementation utilizing intraclass correlation approach. In total 225 quails were used and allotted into three treatment groups: T0 (control), T1 (control + 0.06% betaine) and T2 (control + 0.12% betaine). Each treatment was repeated five times with 15 quails each. Egg production data was collected for 2 clutches (2 × 28 days) started after egg production reached 50%. The data was split and averaged into eight consecutive weeks. Linear model resulted in significant difference of egg production among treatments which were 66.08±18.39%, 70.55±15.11% and 75.46±14.88% for T0, T1 and T2 respectively (P<0.01). Intraclass correlation within each treatment was used as the measure of egg production consistency. Every replicate was recorded in eight consecutive weeks during the experiment. Results showed that T2 has the highest intraclass correlation (0.88), followed by T1 (0.86) and T0 (0.79). Our findings confirmed that betaine supplementation improve quails- egg production in quails. We further discover that the improvement obtained during experimental period due to betaine supplementation was more consistent compared to the quails without supplementation.

Abstract
Economic and social development of a country can be seen from the development of the city. The city is often chosen as a place of residence by some people. With increasing urbanization, it is necessary to manage the city to support economic competitiveness, improve social cohesion, preserve the environment, and improve the quality of life of its people. Smart city, with one of its dimensions, smart technology comes as a solution. This research is based on previous research by Indrawati, Setiawan, and Amani (2017) regarding indicators and variables on smart technology in Bandung. The aim is to find out and produce the index value of smart technology readiness in Bandung. This research is a mixed method with the aim of explorative and descriptive and the type of ethnographic investigation. Data collection is done by literature studies, interviews, observations and surveys. The source of this research is based on the quadruple helix method which consists of government, business players, researchers and experts and the user. To produce an index value for the application of smart technology in the city of Bandung, data on implementation in Bandung were presented to be compared with the implementation of smart technology in Singapore as a data best practice. Based on the results of data processing, the index value of the application of smart technology in Bandung is 72.89. This shows that the level of readiness of smart technology in Bandung City is quite good and satisfying, but in some cases, there are still shortcomings. The highest indicator is in "Number of Formal Education and the Lowest Indicator is in" Archiving Log " Based on the results of the study, the lowest value is found in the Security Information variable, so the government must begin to care about the security of data in smart applications in the City of Bandung.

Abstract
Food is closely related to the principle of social identity, our daily activities with another person has sacred or worldly. In addition, culinary culture also has a certain meaning for the audience. Every food which in is used of part a cultural ritual that always has a symbolic side, meaning and morals that represent its cultural identity. Petis is an inseparable food from Maduras various culinary recipes. Petis symbolizes the proof and symbol of the hard work of the coastal communities of Madura. Petis can be interpreted as a hope of the community and shows the existence of a Madurese ethnic identity that distinguishes it from other communities. This paper is part of research on the cultural identity of migrants in Madura. The purpose of this study was to determine the relationship between people with food, which can reveal a lot of information about them. The choice of food is able to expose a group or a persons belief, passion, background knowledge, assumptions and personality. food choices and eating habits understood to be related to the phenomenon of socialization and social bonding, the construction of collective identity under which to show the logic of social distinction and organization of life in society.

Abstract
There has not been much research on Javanese Gibbons (Owa Jawa). There have been no studies on parental-care in Owa-Jawa, especially about rough-and-tumble-play. This is a means of parent learning to children to protect themselves from predators and to survive in the wild. We want to find out how the pattern of childcare in Owa-Jawa when they are in captivity. In searching for data, we used literature studies to find out about wild-life data on Owa-Jawa, and used observations to determine parenting patterns in captivity. Observations were carried out in ..., in West Java. We use habituation methods in gathering data. We found that the rough-and-tumble-play was also carried out by the Owa-Jawa father towards his female offspring, in captivity. We conclude that there is a difference in the pattern of care for Owa Jawa in the wild that we found in the literature from those data we found Owa-Jawa in captivity. We need further observation regarding the causes of changes in this parenting pattern.

Abstract
Urbanisation is expanding exponentially while the resources to help manage and provide social services is limited. UN-Habitats projected that 75% of the world population will be living in cities in next 30 years and in the same vein more than 5 times of the global GDP will be invested in urban infrastructure and its uses. The overall objective is to provide in-depth insight into urban ecosystem and establish linkage to biosphere through reducing greenhouse gas emission in order to enhance standard of living of inhabitants of the cities. The socio-ecological theoretical framework is used in this discourse as a guiding principle to help better understand the subtle of the subject matter. Some emphasis is placed on functionalist theory to establish the relationship between different parts of society and its environment. Consequently, qualitative methods were used in this article to give narratives and observation of the urban ecosystem. A detailed description and secondary data are used in these deliberations to give account of the severalty of urbanisation and how urban ecosystem can be a remedy to socio-ecological problems. In conclusion, urban ecosystem comes to address the environmental problems and climate change issues to become resilience by improving the wellbeing of the people. Urbanisation should be checked and managed to cater for the needs of the present with compromising the needs of the future generation to come.

Abstract
Dental implants have become a standard therapy to replace tooth loss. The healing process around implants is a complex process to explain whether the host can receive implant material and gain a perfect recovery process. In some cases these implants are unsuccessful because the infection or lack of oseointegration. This is called "early implant failure". Some things contribute to this situation such as surgical trauma, local and systemic factors, and genetic polymorphism factors. Increased levels of MMP-1 have been shown to occur in the sulcus fluid around implants that caused oseointegrated failure and periodontitis. The increase in MMP-1 titers is related to the degradation of collagen which has the most role as an oseointegrated molecular marker. The aim of this study was to develop a non-invasive method for genetic molecular diagnosis on dental implant patients through blood sampling at dental implant sockets. Method : the total 7 subjects, consisted of 4 men with an average age of 46.7 years and 3 women with an average age of 48.3 years. Genomic DNA examination was carried out through DNA extraction using the phenol-chloroform method. DNA amplification was carried out at the MMP-1 locus at 269 bp. The results of DNA isolation were examined for DNA purity and concentration, then used as a reference for determining the amount of DNA in the amplification of the MMP-1 locus by PCR usingMMP-1 primers. Electrophoresis was carried out using 3% agarose gel stained with EtBr. The electrophoresis results of all samples showed DNA band at 269 bp. This proves that DNA exploration in the dental implant socket is a non-invasive method, safe for patients and can be used in genomic analysis methods

Abstract
This article aims to examine and analyze the phenomena of the 2019 beauty trend, and how consumers make cosmetic purchasing decisions. Nowadays, facial makeup seems to be a complement to fashion, especially for working women. Because it is in direct contact with the body, natural and holy cosmetics are very important for Muslim women to work. cosmetics with halal certification are now widely produced, because of the enormous interest of consumers. however, at this time there are also many cosmetics that use hazardous chemicals, alcohol, and some even contain a mixture of unclean animals, such as pigs and dogs. This article intends to review whether product attributes and halal certification in cosmetics influence purchasing decisions in working Muslim women. This study uses quantitative methods with data obtained through questionnaires and measured by a Likert scale. The results of this study shows that the product attributes and halal certification in cosmetics influence the purchasing decisions of working Muslim women.

Abstract
Bone is one of the bodys part which can repair from damage. Bone damages can be caused by trauma, tumors, infections, congenital defects, and also due to surgical procedures. If not treated well, alveolar bone will lose its volume by 40% -60% within 3 year, and the 10% of bone regeneration due to fracture or trauma experiences delays or failure to union. GBR is a technique using a barrier membrane that is placed into the bone defect to provide bone cells with space intended for bone regeneration to increase bone formation which is grows slower than fibrous tissue The pore size of the barrier membrane is very important to prevent excessive fibrous tissue into the defects site and to facilitate neovascularization and bone formation. Objective: This study aims to determine the porosity of DDMM. Method: Bovine dentin is carried out by the process of demineralization and freeze drying until the enamel tissue dissolves. Dentine is cut to a size of 5x5 mm with a thickness of 0.5 mm. Perform double packaging and sterilization using gamma irradiation rays. Membrane porosity seen through SEM examination. Gold coating is done to remove the weak conductivity from the sample before examinating. Samples are put in the sample room at a voltage of 20kV and an magnification of 300. The image is obtained by detecting a secondary signal emitted of sample by an electron beam which produces a CRT (Catode Ray Tube) screen image. SEM micrographs are converted into binary images and further analyzed by Image J software. Conclusions: The average porosity size of the samples seen is 300-500 μm. This porosity size is ideal for GBR membranes that can increase cell proliferation and aggregation to defect sites, as well as good permeability, neovascularization and nutrient transport.

Abstract
This study aims to analyze the financial ratios of banks to predict bank bankruptcy in Indonesia. Variables used by a number of seven bank financial ratios are CAR, LDR, NPL, BOPO, ROA, ROE and NIM. The research data is obtained by census which means the whole population is used in the research which is 33 banks in year 2013. The analysis tool used is logit regression. The results of the multivariate test showed that the LDR variable had a significant effect on the profitability of bankruptcy of banks in Indonesia at α> 5% but did not have the same sign as predicted. CAR, NPL, BOPO, ROE, and NIM variables have the same mark as the predicted but not significant. The ROA variable is not significant and has a different sign than predicted. In general, the results do not accept all Ha. The accuracy of bank bankruptcy predictions in 2013 amounted to 94.7%. Therefore, the level of errors made in predicting bankruptcy is type II, that is, banks that are predicted to go bankrupt are not bankrupt.

Abstract
Inter regions price disparity of cement in Indonesia has negative impact on infrastructural development. One of ways to minimise the above impact is by proposing one price policy for cement commodity. This study aims to address barriers that will arise if a single price cement policy is implemented and propose policy to reduce cement prices disparity between regions. Questionnaires and Focus group Discussion (FGD) are the instruments to collect data. These data were analysed using Regulatory Impact Assesment (RIA). The study found that the cement price disparity only occurs in some remote and border areas where logistics facilities are far behind. Also, it was found that one price cement policy would be difficult to be implemented. The reasons were due to 6 barriers: (i) logistical costs from factories to consumers; (ii) differences in the policies for regulating freight transport that vary between regions; (iii) production centers in Java while consumption spread throughout Indonesia; (iv) ownership status of private cement factories; (v) limited and varied frequency of transportation of transportation modes; (vi) consumers perceptions of cement brands vary in each region. However, from the perspective of CBA of RIA approach, there are only two policies that need to be considered seriously, those are, regional targeted subsidy and ceiling regional retail price policies.

Abstract
The utilization of retail market access in ASEAN as the result of the ASEAN Framework Agreement on Services (AFAS) negotiations is still considered low. Even though Indonesias retail services have potential to expand its business to ASEAN market which its economic growth and population continue to increase. This study used Hoekman Index analysis to see the level of openness of foreign retail services investment in ASEAN countries and SWOT analysis to find the strategies to utilize AFAS in order to increase Indonesias investment on retail industries in ASEAN market. The results of the analysis concluded that the level of investment openness of ASEAN member countries for foreign retail services is relatively open. However, Indonesia is less open than other ASEAN countries. Furthermore, based on EFAS / IFAS Analysis, Indonesias retail service sector has Opportunities and Strength as capital to develop its business in the ASEAN market with a strategy Progressive. As for other alternatives penetration strategies (entry mode) can be done, among others through full investment with foreign ownership of 100% to countries that have been fully open, joint venture, or sell Indonesian retail business master franchise to ASEAN countries, which is the easiest and least risky way.

Abstract
Lactobacillus casei is one of probiotic bacteria which have an antibiotic (tetracycline) resistance encoded by tetM gene. This gene can be unstable which lead to changes in the DNA sequence (mutation) during the adaptation process under sub-lethal dose of tetracycline antibiotic. The aim of the study is to observe the resistance level and genetic instability of tetM gene under sub-lethal dose of tetracycline antibiotic and to examine the effect of gene instability on the antibiotic resistance level of L. casei. This study was conducted by 2 steps e.g. determination of sub lethal dose of L. casei and to isolate L. casei with the highest resistance to tetracycline using adaptation process. This study confirmed that L. casei could survive with sub-lethal dose of 10-50 µg.mL-1 tetracycline and has a lethal dose at 60 µg.mL-1. The concentration of more than 60 µg.mL-1 tetracyline made the instability of tetM gene lead to the survival of L. casei at 70 µg.mL-1 tetracycline after adaptation process.

Abstract
The presence of technology changes the way humans communicate from the real world to cyberspace. Based on Hootsuite Wearesocial research released in January 2019 shows that social media users in Indonesia reach 150 million or 56% of the total population. There has been an increase of 20 million social media users in Indonesia compared to last year. Meanwhile, the Indonesia update website notes that in January 2019 the users of internet in Indonesia reached 91%. The development of this digitalization indicates that the use of social media as a new media is increasingly massive. The massive use of new media is changing the news production platform. In this era, the news is not only from mass media, but everyone can produce news, shape public opinion, and create virtual society. This condition causes public spaces to be filled with hoaxes, fake and false news. In the post-truth era those kinds of news are nearly conquered the world. This condition has a destructive power because it can spread quickly and can produce very strong emotions. This paper discusses the characteristics of Indonesian language impoliteness on social media at the post-truth era by using qualitative research methods. The data is collected from Facebook and Instagram in 2018. The analysis shows that there are language impoliteness markers that are used by citizens on their status. The use of impoliteness is mostly about ethnicity, religion, race, and groups (SARA). Ethnic impoliteness on Facebook media was found to be 5%, religious impoliteness was found as much as 30%, race impoliteness was found as much as 11.6%, and group impoliteness was found as much as 50%. The impoliteness on Instagram shows that ethnic impoliteness is 5.7%, religious impoliteness is found as much as 22.8%, race impoliteness is found as much as 24.2%, and group impoliteness is found as much as 33%.

Abstract
Abstract. Biodiesel was produced from Kapok seed (Ceiba Pentranda) oil (KSO) using heterogeneous bimetallic oxide of copper and zinc supported by γ-alumina. The Alumina-supported copper oxide- zinc oxide (CuO- ZnO γ /- Al2O3) further notated by ACZ was synthesized using precipitation, impregnation and gel methods. It also was characterized using the X-ray diffraction (X-RD), Brunauwer-Emmett Teller (BET), and scanning electron microscopy-EDX (SEM-EDX) methods. Before being transesterified the KSO was pre-treated to reduce gum and free fatty acid content. The activity test of ACZ catalyst was done by introducing it through the transesterification process of KSO with methanol. The transesterification process was conducted in a glass batch type reactor with refluxed methanol. The effect of loading ZnO (wt. %), calcinating temperature (°C), and calcinating time of catalyst (h) on the yield of biodiesel were investigated, respectively. The results showed that the kapok seed oil was worthy and potentially to transesterified into biodiesel using ACZ catalyst.
