Batang Gadis River, located in Mandailing Natal, faces a severe threat by the increase of human activities along the river. The fish community, as well as other biotas, is exposed to reducing environmental condition. Therefore, the study of fish community in this river is essential to get the most recent condition as a baseline data. The purpose of this research was to determine the species diversity of fish in Batang Gadis River of Mandailing Natal. This research used a descriptive exploratory method by surveying with purposive sampling method to collect samples at four specified stations. This study used a fishing net with a zig-zag pattern of sampling covered the river bank for about 200–300m at each observation station. The collected fish samples were identified at the Biology Laboratory of the University of Muhammadiyah Tapanuli Selatan. This study found ten species of fish from five families. The family with the most significant members was Cyprinidae (6 species), and the other families, Bagridae, Clariidae, Nemachelidae, and Loricariidae, were found with only one species. The species diversity comprised of Rasbora lateristriata, Nemacheilus fasciatus, Mystacoleucus marginatus, Tor tambra, Cyprinus carpio, Clarias bathracus, Rasbora argyrotaenia , Barbonymus gonionotus, Puntius binotatus, Bagrus nemurus, and Pterygoplichthys pardalis. The fish population of Batang Gadis River has diversity index (H’) of 1.77 and similarity index (E) of 0.77.

Insecticide use has produced negative impact by affecting the non-target predatory organisms in nature, one of which is the entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae. Interactions occur, however, between insecticides and the entomopathogens. The combination of insecticides at a low dose and an entomopathogenic fungus can work synergistically to increase pest insect mortality. This combination is particularly advantageous because it decreases the insecticide dose applied, reduces environmental contamination, and decreases pest resistance. The study purpose was to determine the compatible working insecticide dose and the entomopathogenic fungi B. basiana and M. anisopliae. The experimental design applied completely randomized design consisting of 15 treatments and four replicates. There were five types of insecticides with three different doses each (0.5 × Dose of Field (DF), 1 × DF, and 2 × DF), whereas the fungal isolates included B. basiana and M. anisopliae. The parameters observed were the germination percentage of conidia, the percentage of inhibition, and the number of conidia.ml-1. Data were analyzed using ANOVA (5% error rate). The mean values were analyzed by DMRT p < 0.05. Deltamethrin 0.5 x DF, and imidacloprid 0.5 x DF demonstrated the highest conidial germination in B. basiana and M. anisopli, respectively. Insecticides showing the highest vegetative growth on B. basiana and M. anisopliae at 7 DAI was imidacloprid 0.5 x DF, while at 14 DAI was imidacloprid 0.5 x DF and chlorphyrifos 2 x DF, respectively. The highest conidial production of the fungi was triggered by imidacloprid 0.5 x DF. Based on compatibility calculation, imidacloprid 0,5 x DF worked with B. basiana (BI: 67.77) and M. anisopliae (BI: 67.16).

Spiny Lobster, Panulirus homarus, farming is very potential to be developed in Lombok Island, but physiological aspects such as nutrient needs and growth hormone, especially ecdysone titer, were little known. This research aimed to determine the ecdysone titer of Panulirus homarus during the last pre-molting phase. This study was conducted as a quasi-experiment with one group post-test design. The lobsters used in this experiment have the length of carapacs and the body weight of 1.5–2.0 cm and 4.33–5.77 g respectively. The lobster fed for 42 days with gel pellets three times a day before ecdysone titer measurement. The ecdysone hormone was then isolated from the second segment of the abdomen on the basal of the fifth pereiopod. Ecdyson titer was measured by using High-Performance Liquid Chromatography (HPLC). The result showed that the titer of ecdysone was 5.27 µg/ml hemolymph. The titer of ecdysone was found higher compared to previous research on Homarus americanus; this result suggested that the spiny lobster Panulirus homarus needs a higher amount of ecdysone hormone to initiate the molting process.

Studies of Sumatran elephant behavior that include the typical behavior of each elephant individual is significant to support ecotourism activities. Information on the elephant behavior obtained by scientific observation can be presented to tourists to provide exciting insights and knowledge during their visit to the Way Kambas Elephant Conservation Center (PKG). This study aimed to determine elephant behavior based on gender, age, the origin of capture, the training time, and also to examine the elephant behavior in supporting ecotourism activities in PKG Way Kambas. The results indicated that the behavior of Sumatran elephants could be determined by sex, age, the origin of capture, and the training period. The male elephant has a more aggressive response than female elephants. The mahout efficiently instructed the adult elephants than the baby, toddlers, and youngsters elephants. The elephant's behavior born in PKG compared to those from capture in the wild were different. Those born in PKG were easier to tame than elephants from outside PKG. Duration of training was also influential to elephants behavior, the longer they were trained, the tamer the elephants. The training was prepared to elephants so that the elephants can be safely presented and familiar to tourist to raise fund for PKG primarily to support the elephant caring and handling.

The success of artificial insemination is determined by the quality of the frozen semen used. Free radicals and cold shock may reduce the quality of frozen semen. These can be prevented or reduced by the addition of antioxidants. Dragon fruit skin extract is rich in natural antioxidants. This study is aimed to analyze the effect of the addition of dragon fruit skin extract on quality (motility, viability, and abnormality) of frozen goat semen. The most effective concentration in frozen semen. The true experimental research was used with the posttest-only control group design. Data analysis was done by using One Way ANOVA followed by Duncan's test of 0.5% assisted by SPSS 22. The research was conducted in May–June 2017 at BBIB Singosari, Malang. The result showed that 0.50% concentration gave the highest motility (26.00 ± 6.51%) and the lowest abnormality (5.6 ± 2.7%), while at 0.75% gave the highest viability (61.60 ± 8.11%). It can be concluded that there is a significant effect (p < 0.05) addition of dragon fruit’s rind extract to the frozen semen quality (motility, viability, and abnormality) of ettawa goat and the most effective extract concentration varies on each quality parameter.

Brucea javanica (L) Merr is a local plant used traditionally for diabetic medication in Lombok Island. The B. javanica seed has been recognized to have an antidiabetic effect, while the impact of the leave extract was understudied. The purpose of this research was to determine the effect of B. javanica leaves infusion on the blood glucose level of alloxan-induced diabetic rats. B. javanica leaves extract were applied by soaking leaves into hot water (95°C) to obtain the extract concentration of 5% (w/v). This experiment provides four treatments to rats within 15 days with five replicates for each treatment. The treatments for rats were K1 a positive control, K2 a negative control, K3 a healthy control, and P1 treated with leave infused water. The diabetic condition for K1, K2, and P1 was induced with an intravenous injection of 125 mg/kgBW alloxan monohydrate to the rats. After stable diabetic condition, K1 rats were treated with Glibenclamide (0,25 mg/kgBW), K2 rats were untreated, P1 rats were administered with leaves infused water of B. javanica (L) Merr 3 ml/day. K3 rats were uninduced and untreated. The hypoglycemic effect was observed by estimating the fasting blood glucose level of the rats every three days. After 15 days of treatments, P1 rats blood glucose level reduced by the 13,30%, while K1 rats 22,04%. The decrease in blood glucose level of both K1 and P1 rats have not reached the average blood glucose level of healthy rats. The result of the statistical analysis showed the infused extract effect was not significantly differed compared to positive control (P < 0.05).

The Siamang, Symphalangus syndactylus, an arboreal black-furred gibbon member of the family Hylobatidae is listed as an endangered species by IUCN since 2008. The main threat to Siamang is the degraded habitat in term of quality and extent due to fragmentation. Protected forest Register 28 Pematang Neba located in Kabupaten Tanggamus is an example of the Siamang habitat threatened by the surrounding land conversion. This study aimed to determine the vegetation structure and profile of the Siamang habitat and to determine the diversity and abundance of plants the diet of Siamang. This study was a survey, and the observation was conducted from July to August 2017 applying three belt transect in the Protected Forest Register 28 Pematang Neba. The vegetation structure and profile of the Siamang habitat showed the distance between trees was more than 4 m that influence the Siamang activity in foraging, resting, and playing. The IVI showed a moderate category at the level of 130.813%, 135.948%, and 122.98% for habitat 1, 2, and 3 accordingly. The diversity index showed a moderate category at the level of 2.905 and 2.762 for habitat 1 and 2 respectively, and a high category for habitat 3 at the level of 3.066. The similarity index values among habitats were considered high (69-81%) allowing Siamang to migrate between habitats. The variety of Siamang diet was composed of leaves, fruits, and flowers.
