Abstract
The existence of organic waste is believed to be the cause of changes in the physical and chemical parameters of the river environment, which have an impact on the diversity of macrozoobenthos in it. However, not many studies have revealed what variables are highly correlated with macrozoobenthos diversity. This study aims to determine the impact of shrimp pond waste inputs and the variables that most correlate with macrozoobenthos diversity. This quantitative descriptive study uses purposive random sampling technique. Sampling was carried out at five stations along the Kali Jeruk - Trenggalek, East Java stream with three repetitions. The identification of macrozoobenthos was carried out in the Fisheries Laboratory while testing physical and chemical parameters was carried out in the laboratory of Perum Jasa Tirta - Malang, East Java. The diversity of macrozoobenthos was analyzed using test principal component analysis (PCA). The results showed that macrozoobenthos were found in ten species from three classes, seven families, and nine genera. Meanwhile, the parameters that correlate most strongly with macrozoobenthos diversity are dissolved oxygen (DO).

Abstract
Drosophilas behavioral studies can facilitate investigations related to human disease as well as various questions about behavioral neuroscience. The aimed of this study was to examine the effect of strains on various Drosophila behavior parameters. The strains used were wildtype, white eyes, and vestigial wings. Larval Crawling Assay, Larval Climbing Assay, Locomotor Assay, and Adult Negative Geotaxis Assay were used as procedures for data collection. Then, the research data were analyzed using a one-way multivariate analysis of variance (MANOVA). The results showed that differences in strains were able to cause differences in Drosophila behavior, especially during the imago phase. The use of wild-type strains is recommended for use as a behavioral study on Drosophila, given the differences in wildtype and mutant behavior recorded in this study. This research is expected to be the basis of Drosophilas behavior study, which is still rarely conducted in Indonesia.

Abstract
Asian sebass, barramundi, Lates calcarifer (Perciformes, Latidae) was first described in 1790 by the name of Holocentrus calcarifer by Bloch. The name of genus Lates by Cuvier & Valenciennes (1828) was given to comprise other species, including Nile perch (L. niloticus). Lates calcarifer is a type of fresh-seawater fish that has high economic value comparable to salmon and tuna. The population of Asian seabass in Australia, Myanmar, Sri Lanka and Japan was reported in different types. Lates lacdiva from Sri Lanka had a lower height than L. uwisara (Myanmar) and L. calcarifer (Australia). However, the attempt to describe and assess the diversity of Lates in Indonesia, including in the Bone Bay and Makassar Strait have never been done. This study analyzed the morphology and genetic diversity of barramundi caught in the Bone Bay and Makassar Strait waters as an effort to document and map species richness. Both morphological and genetic diversity of barramundi caught in both sites were low. The body was elongated with black caudal-fin. Barramundi from Bone Bay had a white-silver color, while those from the Makassar Strait were greenish in color. Dorsal-fin was divided in two parts with base of second dorsal fin less than that of first dorsal-fin. Third dorsal-fin spine longest. Dorsal-fin spines of Asian seabass from the Makassar Strait were more varied than that Bone Bay. Anal-fin spines of Asian Seabass from Bone Bay were varied than that Makassar strait with third anal-fin spine longest (III>II>I). The pectoral-fin was shorter than the pelvic-fin. The pelvic-fin did not reach the anus and generally separate, but in some specimens are fused by a thin membrane. Caudal-fin was rounded and consisted of 15-18 weak spines. Body height was 29.30- 33.35% to standard length (SL), with certain specimen was found with height up to 37.50% from SL. One small spine in the operculum with a position above the lateral line, and 4-5 small spines at the bottom of the pre-operculum. The highest genetic distance was 0.16% while the number of haplotypes was two with 0.00045 nucleotide diversity.

Abstract
Diabetes Type 2 caused by insulin resistance. The majority of insulin resistance is characterized by hyperglycemia and obesity. Obesity is caused by high fat diet and causes side effects of fatty liver. Fatty liver will cause toxic lipid metabolites to increase, causing liver mitochondrial dysfunction and insulin resistance. Liver mitochondrial dysfunction results in fibrosis, cirrhosis, and SGOT enzymes will be released into the bloodstream, which results in increased SGOT in the blood. The purpose of this study was to study the combination of purple sweet potato extract and black soybean tempeh on liver cell necrosis and level SGOT. Rats made Type 2 DM with permeate High Fat Diet (HFD), 10% sucrose and Streptozotocin (STZ) injection intraperitoneally Multiple Low Doses. The treatment was carried out for 30 days with 8 treatment groups. Surgery is take blood samples and liver organ to be prepared. Blood is centrifuged to get blood serum. The serum was mixed with SGOT reagents and measured the absorbance using spectrophotometric methods. Preparations were stained using the Hematoxylin-Eosin method to see the percentage of liver cell necrosis. The results of the study after analyzing one-way ANOVA showed that purple sweet potato extract and black soybean tempeh had a significant effect on reduced the SGOT levels was 168 U/L and percentage of necrotic cells was 32,4%. In the future, it is expected that black soybean plants can be used to be processed into large-scale tempeh and marketed to surrounding communities and the rate of diabetes can be prevented.

Abstract
Tokay gecko (Gekko gecko, Linnaeus 1758) is a small country lizard animal that has a diverse skin color that is decorated with red spots to orange on its back. The study of variations in morphology is very important in various aspects, especially in describing the definition of a species. This study aims to determine the morphological variations based on morphometry and meristic of Gekko gecko in each population. In this study PCA and UPGMA analysis were carried out. The design in the study begins with the measurement phase of 24 morphological characters. The results displayed will be eigenvalue tables, scatter plot graphs and dendograms. The results obtained were then analyzed descriptively. A total of 122 samples of Gekko gecko (male = 81; female = 41) originating from various populations showed a number of character variations between individuals and populations. On certain islands have dominant characters in each population even though these characters are also found in other populations with relatively small values. Gekko gecko in the six populations illustrates overlapping groupings and no significant or dominant character has been seen so that no special character can be found that can be used as a diagnostic character in the Gekko gecko population in a particular population.

Abstract
Land-transmitted worm infections (STH) are a health problem which is prone to occur in children in Indonesia. This worm infection is also one the causes of the high prevalence of stunting in infants in Malang city with an incidence of 3,029 cases. It is assumed that consumption of raw vegetables without proper washing facilitates has been the spread of worm eggs in populations in Malang City. This study was designed to determine the rate of contamination of Soil-transmitted Helminths (STH) Worms in lettuce (Lactuca sativa) in the traditional market of Malang City. A total of 17 vegetable samples from vegetable traders from several markets in Malang were collected for laboratory tests. These samples were tested by microscopic examination to detect the presence of parasites. The results of this study indicated that Ascaris lumbricoides eggs were more dominant in vegetables (82.5%) compared to Ancylostoma duodenale eggs (17.5%). The prevalence of Ascaris lumbricoides worm eggs in Blimbing Market and Big Market in Malang city is higher than the prevalence of hookworm eggs. This study concluded that lettuce vegetables in the traditional market of Malang city were potential for parasitic infections transmission, especially Ascaris lumbricoides worms. Thus, early prevention is needed for these spreading parasites with intensification of hand washing and vegetable washing processes with standardized methods.

Abstract
Rheumatoid arthritis ( RA) is one of autoimmune disease because of oxidative stress that would increase the number of CD4+ cells. It will cause inflammatory and damage in synovial membrane and joints. Conventional therapy which used to overcome inflammatory by administering non-steroid anti-inflammation drugs (NSAID) are able to make bleeding and damage gastrointestinal tract and liver. Red betel (Piper crocatum) content flavonoid which has oxidant activity. This research was conducted to determine the effect of red betel leaf extract on the number of CD4 + cells and to find dose are able to reduce number CD4 + cells in RA mice. The animal used were eight weeks of male balb C strain mice were eight weeks with ranged of weight from 28-30 grams. Mice will divide into six groups (normal, RA without therapy, aspirin therapy, therapy by red betel leaf extract dose 100 mg/g, 200 mg/g and 400 mg/g). Each treatment was delivered by gavage with 0.5 ml for 21 days. At the end of treatment, The mice were sectioned and lymphocytes were isolated to count the number of CD4 + cells using flowcytometry. The results showed leaf extract of red betel has an effect to decrease the number of CD4 + cells on RA mice, whereas leaf extract of red betel optimal dose is 200 mg/g and has a tendency to decrease the number of CD4 + cells.

Abstract
Indonesia possesses abundant biodiversity and endemic if compared to biological wealth in other regions in Asia. One form of animal biodiversity in Indonesia is characterized by various types of complex morphological forms, for example in poultry groups. Frizzle chicken is one of the poultry species that have unique morphological characteristics. However, the characterization of morphology and molecular physiology in chicken frizzle in Indonesia is rarely explored until now. This study was conducted to characterize the specific characteristics of Indonesian chicken frizzle by analyzing several parameters such as feathers, scales on the feet and head morphology between local Javanese frizzle chicken and wild-type types. Based on the comparison of the morphology through the parameters above, it was found that there were significant differences between chicken and wild-type frizzle, including curvature, weight, length of fur, and morphology of the head and foot scales. Interestingly, Indonesian frizzle chicken has a more colorful variety of feathers compared to other areas. Thus, the results of this preliminary study are worth-using as the basic frameworks for genetic mapping of species of chicken frizzle in Indonesia. Further research is needed at the molecular level to obtain a comprehensive database of Indonesian frizzle chicken.

Abstract
Many peoples having an unhealthy lifestyle, like consuming fast food which has a high-fat content. There are many types of research using HFD (High Fat Diet) woof. HFD composition consists of many various contents. Consuming a HFD can cause several negatives health consequences, including metabolic dysfunction and obesity. The purpose of this study is to know the role of HFD which used our composition in the hyperlipidemic-mice model. Eight weeks old balb-C mice divided into two groups, normal and high-fat diet. Both groups received treatment for four weeks. The proximate test was carried out on both HFD and normal woof. Bodyweight and energy intake were measured at the end of the study. The result shows that the HFD group had a bigger body weight and energy intake. The proximate test showed that HFD contained lipid, protein, saccharide higher than normal woof. These are supported by the proximate test of HFD woof that contains protein and lipid higher than normal woof. The conclusion is HFD increasing body weight and energy intake higher than normal.
