Abstract
Background : Exclusive breastfeeding provides short-term and long-term benefits for babies and their mothers. This is related to the risk of reducing morbidity and mortality in infants, and improving maternal health. This support was obtained by mothers from two parties, namely family and health workers. The purpose of this systematic literature review is to determine the effect and effectiveness of husband and care provider support for exclusive breastfeeding. Methods: The five stages of the Systematic Literature Review method are identifying problems, determining priority problems and research questions, compiling a framework of inclusion and exclusion critical data using PICOC, searching for literature using the PubMed database with a period of 2008-2018, conducting a critical appraisal to determine quality from an article, data extraction analysis and literature mapping. Results: There were 8 articles selected using quantitative research methods with various types of study designs such as quasi-experimental, case control, randomized control trial (RCT), and cross sectional study. There are 3 articles that provide an explanation of the effectiveness of family support, 4 articles that provide an explanation of the effectiveness of care provider support, 1 article finding that provides an explanation of workplace support for exclusive breastfeeding and 3 articles that provide an explanation of family support and care providers for duration of breastfeeding. Conclusion: Support from family and care providers turned out to have many benefits. The influence that can be received is the existence of motivation from the family itself, namely from the husband and grandmother of the baby. Then the task of the care provider itself can provide support through direct counseling to nursing mothers and families especially baby husbands and grandmothers to continue to provide support to mothers.

Abstract
Abstract City open space is an open space within a city, commonly used for parks, green spaces, and other open areas. The landscape of the city open space can range from playing fields to highly maintained environments to relatively natural landscapes. It has significant function for city environment. Palangka Raya city is a small-medium city located in Central Kalimantan Province, Indonesia. The city is surrounded by forest 285,349.28 hectares while size of the city itself is 168,000 hectares with population 376,647 people. According to Burgess, small-medium city is a city with population more than 100,000 people but little bit less than the minimum number of population categorized as a medium city which is 500,000 people. The use of open spaces in such a small-medium city like Palangka Raya city is mainly for public activities and interactions and environmental function. It is equipped with public facilities at certain level and is planted by vegetations. This research will measure scientifically the use of the open spaces for public activities and environmental function, hence city policy on development of city open spaces can be formulated to increase benefits from the existence of city open spaces within a small-medium city.

Abstract
Mental health problems in Indonesia are very important public health problems. Stigma on people with mental health disorders is one of the inhibiting factors that needs to be minimized. Adolescents are a group that needs to get this knowledge but become a group that has not received special treatment. The study aims to develop interactive approach (gamification) to support the socialization process and increase understanding on mental health. This is a pre-posttest study design using Carpe Diem Board Game. A total of 24 participants recruited through a purposive sampling and participated in the board game trial. Pre and post-test using the Depression Literacy focuses on two aspects: personal views related to depression and stigma as well as personal beliefs about the views of the surrounding environment related to depression and sigma. The results showed the learning process based on the game gives significant results at each point (pre and posttest changes). When the results of the post-test give little value is an indication that the learning process based on carpe diem that has been done is able to provide understanding and minimize the stigma associated with depression. It is concluded that indicate that game-based learning has an effect although some area still need improvement.

Abstract
Academic performance has an essential impact in predicting the success of an educational program. This study was performed to identify the most influential factor in achieving the students academic performance in term of grade point average (GPA) and to identify the assessment method effectiveness. The cross-sectional study design was conducted to 158 medical students of Universitas Islam Bandung to participate in taking a quantitative survey. A questionnaire was adapted from student perception of assessment questionnaire (SPAQ). Data analysis used Chi-square test and ANOVA test with a 95% confidence interval and then proceeded with the Dunnett-s posthoc test. The majority of students have a good perception of assessment method (88.6%). From characteristic of the age, gender, admission test to medical faculty, and perception of assessment method, admission test through special interest and abilities became predictor factor that influencing the achievement of academic performance (GPA) with a p-value of 0.004 (p value> 0. 05). Admission test through special interest and ability (PMDK) highly influences the achievement of academic performance. The assessment system is quite effective in assessing the learning outcome. This is due to the perception of assessment method is more related to student approaches to learning than for achievement of academic performance

Abstract
The current Mycobacterium bovis BCG vaccine provides inconsistent protection against pulmonary infection with Mycobacterium tuberculosis (Mtb). In mice studies, immunity induced by subcutaneous BCG wanes by the time. The evidence for immunogenicity following BCG vaccination in Indonesia is limited. This preliminary study measured Mtb-specific T cell response in peripheral blood mononuclear cells (PBMC) using flow cytometry. Three designs were compared in the stimulation of PBMC with Mtb culture filtrate protein (CFP) and additional protein transport inhibitor Brefeldine A (BFA). They were 24 hours or 5 days of CFP stimulation with BFA at the last 4 or 18 hours. The intra-cytoplasmic cytokine staining (ICS) was then performed to assess the production of IFN-gamma, IL-2, and TNF by CD4+ T cells. Single production of IFN-gamma or TNF detected in the 24-hour was higher than that in the 5-day. The 18-hour BFA resulted in a significant proportion of polyfunctional CD4+ T cells. In conclusion, detection of Mtb-specific T cell response using ICS of human PBMC is optimum using 24 hours of antigen stimulation with additional BFA at the last 18 hours. The duration of antigen stimulation and protein transport inhibition affects the amount of intra-cytoplasmic cytokine response analysed using flow cytometry.

Abstract
Kertasari Sub-District at Bandung District is one of the areas in West Java which has become the center of arabica coffee (Coffea arabica, L.) cultivation. Kertasari arabica coffee has known for it-s specific characteristics and has international sale value. Polyphenolic substances contained in coffee plant parts is one of largest secondary metabolite group produced by plant. Phenol and polyphenolics have important role in long life health care, reduce the risk of chronic and degenerative diseases. The roles may be related to antioxidant activity, antitumor, antiviral, and anti-microbe. Flavonoids which also contained in coffee plant is a part of phenol polymer and known for their antioxidant activity. Beside of the beans, coffee leaves and pulps are also known to have polyphenols and flavonoids, but no information about which plant part of Kertasari arabica coffee has the highest level. Kertasari arabica coffee leaves, pulps, and beans were extracted by maceration with 96% ethanol. The next step was total polyphenols and flavonoids content measurement from each extract collected. The results showed that the level of total polyphenols content in coffee leaves, peels, and beans consecutively were 181.07; 37.05; and 112.39 mg GAE/g extract. Furthermore, based on the measurement results, the level of total flavonoids in coffee leaves, peels, and beans consecutively were 7.98; 5.43; and 6.85 mg QE/g extract. To be concluded, the leaves part had the highest level of polyphenols and flavonoids content in Kertasari arabica coffee.

Abstract
Scabies in Indonesia, especially in pesantren is still a problem in the city of Bandung. Various efforts have been made to treat and eliminate scabies in pesantren, but have not been able to make pesantren free of scabies. The purpose of this study was to determine data regarding the availability of PHBS textbooks in Islamic boarding schools. The study conducted an observational cross-sectional approach to 20 boarding school representatives around the city of Bandung, to find out the PHBS teaching materials used by students and the incidence of scabies in the pesantren visited. Election of pesantren by using random sampling, statistical analysis using t-test analysis. Based on data from the office of the ministry of religion in Bandung city education and boarding schools, there are 174 boarding schools in the city of Bandung. Of the 20 pesantren that were successfully visited, none have teaching materials on clean and healthy living behaviors that used as a guide for students. The highest incidence of scabies was 88%, and the lowest was 10%. The results showed that the presence of PHBS teaching materials was not related to the incidence of scabies. Multifactorial which can cause scabies in addition to teaching materials is a social-cultural factor, climate, clean water facilities, easy access to health services, easy access to health information besides PHBS textbooks. Although all pesantren did not have PHBS teaching materials, the existence did not affect the knowledge of students and the incidence of scabies statistically.

Abstract
Longitudinal regression is a statistical method used to analyze the relationship between one or more independent variables and dependent variables on longitudinal data. Longitudinal data is the result of observation of a study in several different periods. Collecting data periodically causes the correlation in each object observation so that longitudinal data could not be analyzed with the usual regression methods. One of method used for regression analysis of correlated data is Generalized Estimating Equation (GEE). GEE method provides many types of correlation structures that are independent, exchangeable, AR(1) and unstructured. This research has intention to determine the best longitudinal regression models on study case of Human Development Index (HDI) in 2010-2014 used GEE method and four different correlation structures. The best model of it will be determined by using Quasi-likelihood Information Criterion (QIC) test. The result of analysis by seeing the smallest value of QIC is AR (1).

Abstract
The lower mathematical connection and reasoning abilities of elementary school students are the background of this research. This happens because students have not been properly facilitated to develop the ability mathematical of connection and reasoning. Mathematics learning can develop connection and reasoning abilities well because mathematics learning has systematic concepts and conceptual relationships. This will have an impact on logical, systematic and rational ways of thinking. Therefore, teachers must be able to choose learning models that can facilitate the ability of mathematical reasoning and connection. One learning model that can be used is the literacy project-based learning model. This study aimed to determine the effectiveness of improving the ability of mathematical connections and reasoning of students who obtain literacy project-based learning. The design of this research was used pretest-posttest non-equivalent control group. Based on research results, conclusions can be drawn about the effectiveness of learning that includes n-gain, minimum completeness criteria, and mastery learning. Literacy project-based learning is very effective in facilitating connection skills and has been effective in facilitating reasoning abilities. That is because literacy project-based learning can present contextual material with literacy works that are made and invited to carry out the process of thinking about the use of mathematical contexts in daily life. Furthermore, students can connect mathematical material with real-life contexts and can make reasoning to interpret learning well.

Abstract
This research aims to determine the appearance of fat-tailed sheep production by providing rations containing protected and unprotected soybean groats. Protection against soybeans groats using 37% formaldehyde solutions as much as 1% of the dry matter of soybeans groats. The use of protection and unprotected soybeans as much as 15% in rations is given for 30 days before and 70 days after birth. The research treatments were P1 = 25% soybean groats protected and 75% soybean groats unprotected, P2 = 50% soybean groats protected and 50% soybean groats unprotected, and P3 = 75% soybean groats protected and 25% soybean groats unprotected. The research variables include initial weight, weight gain, weight gain, feed intake, and feed efficiency of fat-tailed sheep ewe and birth weight of fat-tailed lamb. The results showed that the difference in the ratio of soybean groats protected and unprotected had a significant effect (P> 0.05) on the feed efficiency of the fat-tailed sheep feed and lambs birth weight and did not affect the performance variables of other production (P <0.05). From the results of the average difference test, it appears that the analysis of variance shows that the highest feed efficiency and birth weight results from the use of rations containing soybean protection and without protection with a ratio of 75%: 25%. The conclusion of the study was the use of rations containing 75% protection of soybeans groats and 25% without protection increased feed efficiency rations in fat-tailed sheep for 70 days after birth and increased the birth weight of their offspring.

Maju Utomo farmer group and Ngudi Berkah livestock group in Wonorejo Village, Gondangrejo District, Karanganyar Regency, Central Java raise Simpo beef cattle fattening. The observation of the research team in both groups, that there was a decline in the performance of fattening production and low acceptance of innovation. For this reason, it is necessary to increase the weight gain of cows by applying the innovative supplementation of growth promoted concentrate for fattening their beef cattle. The purpose of the research is the application of innovation in the use of growth promoted concentrate for evaluating the performance of the Simpo cattle fattening productions and the acceptability of the application of innovative use of growth promoted concentrate in both groups. Research methods include instructional and dialogues through counselling program activities using FGD (Focus Group Discussion) techniques, evaluating progress in the level of knowledge and understanding of the material, training and making growth promoted concentrate, applying the use of growth promoted concentrate for fattening, monitoring and continuous evaluation. The research treatments were P1 = control feed (30% fermented rice straw + 70% basal concentrate) and P2 = P1 + 20% growth promoted concentrate. The research parameters are initial weight, final weight, weight gain, average daily gain, feed conversion ratio, feed efficiency, feed cost going and innovation acceptability. The research data were processed using the t-test variance analysis. The conclusion is to increase the production performance of fattening products using additional growth promoted concentrate. The acceptability of innovations in the application of growth promoted concentrate is influenced by factors of livestock experience, breeders age, number of cows, livelihoods and the outpouring of labour.

Energy consumption for households is used for various purposes, including for cooking, lighting, air conditioning, and others. The cooking process is an activity in the household sector with considerable energy consumption. The fuel that is often used for the cooking process is LPG for urban areas and firewood for rural areas. LPG is a fuel whose price is relatively high and fluctuates with time. In addition, this fuel often has problems with uneven distribution in some areas. While the supply of materials is also increasingly limited over time due to problems with the environment. One solution to overcome these problems is to utilize renewable energy, especially solar energy which is always available throughout the year. The results obtained in this study are the design and manufacture of solar power plant installations that are integrated with electric stoves. This installation is able to heat as much as 20 liters of water and maintain water temperatures up to 70 oC for 6 hours.

Abstract
Law No. 23 of 2006 on Population Administration contains the terms adoption of a child, Acknowledgement of a child, and Legitimization of Children. As stated in the Elucidation to Article 47 paragraph (1) of Law Number 23 of 2006 concerning Population Administration, the notion -adoption of a child- means the legal act to transfer the rights over a child from his parents, legitimate guardian or another person responsible for the care, education, and raising of the child, to the adopting parents, on the basis of a decision or order of a court. With regard to the definition or restriction, the adoption of a child is a legal act with certain purposes and objectives regulated by law and has certain legal consequences, for example, the person who adopts a child will be fully physically and mentally responsible for the child. As stated in the Elucidation to Article 49 paragraph (1) of Law No. 23 of 2006 on Population Administration, the notion -acknowledgment of a child- means a fathers acknowledgment of a child born out of wedlock, with the approval of the mother of the child. The acknowledgement of a child is intended to make the child have a biological father so legally civil relations will arise. The Elucidation to Article 49 paragraph (1) of Law No 23 of 2006 on Population Administration states that the one who can acknowledge a child is the father, not the mother. In other words, automatically, the child does not need to be proven that he/she is not born to the concerned mother. As stated in the Elucidation to Article 50 paragraph (1) of Law No. 23 of 2006 on Population Administration, the notion -legitimization of a child- means the legitimization of a child born out of wedlock at the time the marriage between the two parents of the child is registered. Article 50 paragraph (1) of Law No. 23 of 2006 on Population Administration stipulates that the legitimization of a child must be reported by the parents to the Implementing Agency within than 30 (thirty) days of the father and mother of the child in question marrying and obtaining a marriage certificate. For a child born out of wedlock, a child acknowledgment or a child legitimization can be done. The acknowledgment of a child is only limited to the acknowledgment by the biological father who was approved by the biological mother, without being followed by the marriage of the father and mother. Nevertheless, in the legitimization of a child, the father and mother of the child are married and at the time of marriage registration, the child is acknowledged as their biological child. This legitimization of a child is a legal effort (rechtsmiddel) to provide the child with a status as a legitimate child through the marriage of the parents.
