Abstract
Diabetic nephropathy is one of the complications caused by metabolic disease which could lead to renal failure. A marker that can potentially be used for early detection of diabetic nephropathy is urinary albumin-creatinine ratio (uACR). This study aimed to measure correlation between uACR and the stage of renal failure. Crosssectional study was conducted in March until August 2018. Participants were clinically examined, and blood and urine were taken. the stages of renal failure was determined by estimated Glomerular Filtration Rate (eGFR). Data was statistically analyzed by One way ANOVA and Pearson correlation. Of 107 participants, 79 participants were eligible for inclusion in data analysis. The participants were grouped into 5 stages of renal failure. Urinary albumin-creatinine ratios in stage 1,2,3,4,5 were 204.9, 125.9, 474.9, 604.7 and 2895.6 respectively. Posthoc analysis showed significant differences in uACR between stage 5 and stage 1,2,3 respectively (p<0.05). Significant correlations were found in uACR with SC (r 0.354, p 0.001), BUN (r 0.244, p 0.032) and eGFR (r -0.345, p 0.02) respectively. Urinary albumin-creatinine ratio had positive correlation with serum creatinine and blood urea nitrogen, while had a negative correlation with estimated glomerullar filtration rate

Abstract
Abstract Additives are chemical compounds added to preserve food. There are two types of additives; natural and artificial additives. The durability of wet noodles is relatively lower compared to other staple food. There are various methods to preserve wet noodles. One of which is the addition of natural additives. Natural additives are chosen because they are safer than artificial additives which are more precarious to human health. The natural additives used are carrots because they contain B-carotene compounds functioning as antioxidants that reduce and or deactivate free radical attacks and ROS (Reactive Oxygen Species) on food caused by microorganisms. These processes increase the durability of wet noodles. The research aimed to determine the effect of B-carotene content in carrots as a natural additive for wet noodle preservation. The method used was an experiment with B-carotene concentration variations in carrots; 0%, 20%, 40%, 60%, and 80%. From the results, it was found that at the 60% concentration of B-carotene, the durability of wet noodles reached the maximum 4 day. This fact showed that the addition of high concentration B-carotene will affect the durability of wet noodles. And carrots can be used as natural additives in preserving wet noodles.

Abstract
ABSTRACT At present the public demand for fuel oil (BBM) is increasing inversely proportional to its availability. One of the efforts to reduce peoples dependence on BBM is to utilize alternative vegetable-based energy such as bioethanol. Bioethanol is a fermented product that can be made from a substrate containing carbohydrates. Breadfruit (Artocarpus artilis) is one of the agricultural products that has a fairly high starch content of 89% and is not included as a staple food source in Indonesia. Utilization of breadfruit is still not optimal because breadfruit is only used as a snack or made into flour. This study aims to make bioethanol with breadfruit raw material (Artocarpus artilis). The method of this study consisted of two stages, the first step was hydrolysis of breadfruit flour with a hydrochloric acid (HCL) catalyst. The concentrations of HCL used in this study were 1%, 1.5%, and 2%. The second stage of fermentation using Saccharomyces cerevisiae with 72 hours fermentation time, 120 hours and 168 hours. From the results of the research it was found that the highest levels of bioethanol to the treatment of HCL 2% concentration and fermentation duration of 168 hours was 17.6%.

Abstract
Abstract Cheese is commonly derived from cows milk by separating whey and curds through a fermentation process, involving both aerobic and anaerobic microbial activities. Cheese making is done through a process called milk coagulation with the help of rennet. However, rennet is not easily obtained and rather expensive. Fortunately, rennet can be substituted by cermai fruit extract in this milk coagulation process. The present study aims at determining the concentration of cermai fruit extract thatcan optimally speed up the clumping process of FH cattle milk in cheese making. The extracts were obtained through smooth blending, filtering, and squeezing. Five experiments were conducted using extracts with different concentrations: 50%, 60%, 70%, 80%, and 90%. The results show that 90% is the most optimum concentration of cermai fruit to help the coagulation process in cheese making. The milk coagulated in the average time of 5.4 minutes. To conclude, cermai fruit extract could determine the milk coagulation process time period and can be used as a substitute for rennet

Abstract
Noise-induced hearing loss (NIHL) is the common occupational disease especially for fishermen who using boat for fishing. NIHL is a permanent hearing abnormality caused by prolonged exposure to loud noise and the first symptom is normally the inability to hear high-pitched sounds. The Regulation of Indonesian Ministry of Health 2016, mentioned the safe range of noise maximum is 88 dB with the maximum time of exposure is 4 hours. Meanwhile, the noise caused by boat engine is 77,64-97,8 dB. The objective of this study was to assess the risk factor of boat engine noise towards NIHL in fishermen. Audiometric examination was done to evaluate the samples with normal baseline, 25 dB. The study sample comprised 70 volunteers which devided within 2 groups (fisherman and 35 local resident-non fisherman). This study was conducted in Kedonganan Village, Bali. The study results showed that 77% (27 of 35) of fisherman is diagnosed as NIHL with working hour average ±4,86 hours and ±16 years period of exposure. Group with non fishermen showed 2 NIHL condition eithout any exposure from boat-engine (p<0.05). It is concluded that the the noise from boat engine can cause hearing loss. The fisherman have to wear earplug or earmuff or headset to reduce the risk of noise induced hearing loss.

Abstract
This study aims to determine the effect of compost and biochar and their interactions on the growth and yield of red chili plants. This study used a randomized block design (RBD) with a factorial pattern, which consisted of two factors: compost (0, 10, 20, and 30 tons ha-1) and the type of biochar (bamboo and coconut shell). The results showed that the interaction between compost and biochar did not have a significant effect on all observed variables. The dosage of compost has significant effect on fruit length, fresh fruit weight, and fresh weight of roots. The biochar treatment has no significant effect on all observed variables except for the number of fruits that have a significant effect. The treatment at different dosage levels was not significant, but the compost dose of 30 tons ha-1 tended to produce the highest fresh fruit weight 185.35 g which increased by 20.94% compared to the lowest yield without compost 153.26 g. The treatment of this type of biochar only had a significant effect on the number of chili fruit, namely coconut shell biochar which gave the highest value of 17.17 chilies and was significantly different from bamboo-based biochar which produced 15.00 chilies.

Abstract
One of the conservation efforts of the Lepidochelys olivacea turtle in Indonesia is by saving its eggs on the beach, hatching, rearing and releasing hatchlings into the sea. However, a lack of knowledge in management has affected many turtle eggs that do not hatch and hatchlings that die during maintenance. Breeding activities are controlled incubation and hatching of eggs in order to make L. olivacea more developed and avoid extinction. Eggs are planted at a certain depth of the nest but it is not known at what depth the eggs have good hatchability. The aim of this study was to determine the hatchability of the eggs and morphometric of the hatchlings (Lepidochelys olivacea) based on the depth of the brood nest. This research was conducted in 2016 at Muara Tembulih, West Coast of Lampung Province. The treatment was designed with a Completely Randomized Design in the form of four (4) treatment of egg incubation depth and 6 replications. The results of the study were treatment with nest depth of 40-45 cm, hatchability (70-73%) and morphometric size of the newly hatched turtle hatchlings (body weight ± 23 g; body length ± 7 cm, carapace length ± 4 cm and width carapace ± 3.52 cm) statistically, much higher than in nest depths of 35 and 50 cm.

Lots of duku (Lansium domesticum Corr.) Rupit trees have died in the past ten years. However, no high yielding seedling is available for replanting. In this respect, in vitro propagation offers a perfect solution because it allows growers to get millions of pathogen-free and uniform seedlings at a very short of time for rootstocks. The objective of thi experiment was to have the best combination of 2,4-D and BAP in inducing the growth of duku explants. The experiment was conducted from February to June 2018 at the Tissue Culture zlaboratory of the Department of Agronomy and laid in Completely Randomized Design. Seeds of duku were grown in MS media supplemented with 2,4-D (1, 2, 3 ppm) and BAP (2,3,4 ppm). The results showed that all of the media tested produced callous, with different time of formation and qualities. Also, all media produced shoots, but only MS media supplemented with 2 ppm 2,4-D and 2 ppm BAP produced leaves. However, no media produced any root.

Abstract
One of the maintenance management on broiler chickens is setting the density number of hens in the cage (cage density). Cage density effect on the comfort of the enclosure in the tropics, temperatures and high humidity can be a major cause of stress in chickens. The space of the cage with a level of density that does not negatively affect the performance of appropriate production and meat quality. This research aims to identify the density of the enclosure temperature and moisture origin as well as its influence on the quality of the meat. A complete Random design are used on research with 3 (three) treatment namely 8, 10 and 12 tail density per m2 of space enclosure. Each treatment was repeated 3 (three times). The results showed the difference in density of cage on maintenance of chicken broiler until the age of 5 weeks, no influence on the quality of the meat. Be advised, with a density of broiler chicken research 12 tails per m2 can be done without affecting the quality of the meat and can save space enclosure used.

Abstract
Abstract Diarrhea is one of the most common diseases affecting children around the world. According to the Health Service Data of Gianyar Regency, there are 214 diarrhea morbidities per 1000 population with the most diarrhea cases found in Tegalalang District. The role of mothers in giving treatment of diarrhea is important so that children do not fall into worse conditions. Mothers knowledge and behavior is one of the crucial determinants in giving treatment to children suffering from diarrhea. Mothers should know what steps to do first when the child has diarrhea in order to prevent the occurrence of dehydration. This study aims to determine the level of knowledge and behavior of mothers in the early treatment of diarrhea in Tegalalang District Gianyar regency. This research is a descriptive research by using questionnaire instrument which previously has been validated. The samples of this research are mothers who have children suffered from diarrhea six months prior to the research; the number of respondents is 37 which are determined by consecutive sampling. The data were analyzed using univariat analysis test. The results show that mothers with good knowledge level are 22 respondents (59.5%), mother behaviour with enough knowledge in giving treatment are 18 respondents (48.6%), and those who are still lack in providing zinc and how to give good nutrition. The conclusions of this study indicate that mothers with good level knowledge and mothers behavior with enough knowledge and those are still lack of knowledge in some early treatment of diarrhea on children in Tegalalang Gianyar in 2017. Based on this research, the researcher suggests to the related parties specifically to the Puskesmas (Primary Health Care) to conduct counseling on how to give initial treatment of Diarrhea, which can be done at home continuously and sustainably

Abstract
Abstract Alcoholic beverages are beverages containing alcohol (C2H5OH) which fermented or distilled from carbohydrates. Alcohol can trigger disorders such as cancer, cardiovascular disease, neuropsychiatry, gastrointestinal tract, infection, injury, and neonatal abnormalities. About 38.3% world population aged 15 years and above consumed alcohol, while in Indonesia 4.6%. A quarter of the consumption (24.8%) is illegal, which is homemade alcohols that are produced or sold out of government control. Therefore, the research was conducted with the aim to know the level of knowledge, attitudes, and behavior of people against alcoholic beverages. This research was designed as a quantitative descriptive research with cross sectional approach. Sampling used was multistage random sampling technique, the number of samples were 96 obtained by the formula. The results of this study indicate that the respondents knowledge level is mostly good (67.7%), response attitude is mostly good (63.5%), and the behavior of alcoholic drinkers is more than half (56,1%). Active role of health workers is needed to provide information on alcoholic beverages and the government needs to provide oversight and firm action in the circulation of alcoholic beverages.

Abstract
Papilio memnon memnon is one of the butterflies groups of the Papilio clan in West Java, Indonesia. This study aims were to determine the morphology, behavior, and life cycle of the P. m memnon butterfly. The research method used is descriptive with survey techniques and literature studies. This study aims to determine the morphology, behavior, and life cycle of the P. m memnon butterfly. The research method used was descriptive with survey techniques and literature studies. Data about morphology, duration of life, and behavior at each development phase during the P. m memnon butterfly life cycle were analyzed descriptively based on direct observation. The results showed the egg phase of P. m. memnon takes about 7-8 days to the phase instar1 of the larvae. The average total time needed in the larval phase is around 23 - 45 days to the pupa phase. The Pre-pupa phase lasts 1-2 days, while the pupa phase lasts 2-3 weeks. P. m. memnon performs the larval phase as many as 5 stages of instar. Food eaten by first phase instar 1 of larvae is the eggshell, which is useful for insect growth and helps eliminate evidence of eggs from parasitic attacks. At each phase of development, the larvae eat the outer skin to obtain additional energy to support growth.

Abstract
Coastal ecosystems consisting of mangrove ecosystems, seagrass beds and coral reefs have the potential to be developed as ecotourism. Seagrass ecosystems located in the intertidal zone are an integral part of coastal tourism in the area of study. However, its existence has not received serious attention as a component of coastal ecotourism that can contribute to ecological services. This article aims to start an effort towards empowering this potential through the study seagrasses ecology to formulate the potential of ecological services in supporting the development of ecotourism. Data collection were done through observation, survey and questionnaire methods, and data analysis were done descriptively. The analysis showed that the potential of seagrass community tourism services can be grouped into three parts, namely: (1) seagrass community that form seagrass beds in each tourist location, (2) the diversity of species of biota associated with seagrass can be enjoyed by tourists and (3) seagrass community area can be the location of snorkeling at the time of high tide. The conclusion of the study is that the existence of seagrass ecosystems can provide added value from aspects of environmental services in the development of ecotourism in the southern coastal region of Lombok Island.

Abstract
Abstract Nutritional status is the state of the bodys end result of the balance between the nutrients intake and its utilization. Nutritional problems that usually occur are underweight and overweight. In Indonesia, the prevalence of obesity is 18.8% and underweight is 11.2% which occur in children aged 9-12 years. The prevalence of obesity in children of that age in Bali Province is 20%. Various factors can affect nutritional status such as diet and physical activity. The purposes of this study were to determine the correlation of diet and physical activity with nutritional status in children aged 9-12 years. This study used analytic cross sectional design with 60 samples taken from all students of 4th, 5th and 6th grade of SD Negeri 1 Batannyuh Tabanan that fulfilled the inclusion and exclusion criteria. The variables studied were nutritional status as dependent variable and physical activity as independent variables. The instrument used in this study was a questionnaire that had been tested for validity. Data were analyzed with Somersd correlation test. The results showed that most of the respondents had good diet (51,7%), poor physical activity (53,3%), and normal nutritional status (51,7%). There was a significant correlation with mild positive correlation between diet and nutritional status (p=0,025) and between physical activity and nutritional status (p=0,026). Result of this study are expected to be useful both theoretically and practically in order to perform promotive or preventive actions related to nutritional status.
