Sea snakes have a strong venom and when they bite can be fatal for humans, whereas snakes found in mangrove areas are weak venomous snakes and non-venomous snakes (McKay, 2006). The low understanding public aboutthe snakes has led to the assumption that any snakes found are dangerous, so research needs to be done in order to provide information on the types of venomous and non-venomous snakes present in coastal areas and around mangrove forest areas. This research was conducted from early January to the end of January located around Merta Sari Beach to Padang Galak. The method used is the method of cruising method is done by determining the habitat that is likely suitable for snake habitat (Asad et al., 2011). Data collected in the morning and at night, by capturing and identifying snakes found in situ refers to the snake identification titled '107+ Ular Indonesia' (Riza Marlon, 2014), and the book 'Reptiles and Amphibians in Bali 'By Mckay (2006). Based on the results of the study, snakes found around Merta Sari Beach and Padang Galak Beach numbered 61 individual snakes with two different families namely Colubridae and Elapidae. Snake species of the Colubridae family found are Dog-faced Water Snake (Cerberus rynchops) and the Elapidae family is the Erabu/Yellow-lipped Sea Krait (Laticauda colubrina) snake

Black orchid (Coelogyne pandurata Lindl.) is an orchid endemic to the island ofBorneo. However, its existence is increasingly threatened with extinction. Conventionalpropagation efforts require a long time. Therefore in vitro propagation was performed. Thepurpose of this study was to determine the growth response of black orchids on the media anddifferent planting techniques. Black orchid plantlets that have been sub-cultured wasacclimatized in four different media types ie moss, fern, wood charcoal, wood charcoal andcoconut fiber mixture and different planting techniques namely compot (community pot) andthe individual, were allowed to grow for three months. Randomized block design (RBD) wasutilised, obtained 8 combination treatments, with 7 replicates. The results showed blackorchid has a good growth response in the media moss, ferns, and a mixture of wood charcoaland coconut fiber, while the wood charcoal media showed unfavorable results. Differentplanting techniques showed no significant results. Percentage of high life shown in mixedmedia wood charcoal and coconut fiber and compot techniques.Keyword : Black orchid (Coelogyne pandurata Lindl.), acclimatization, media

Utilization of springs as water resources for their daily needs by the people of Sukawati Sub-Distric of Gianyar Regency, Bali is still quite high Human activities, such as increasing domestic, industrial and agricultural activities, have an effect on decreasing water quality. This research was conducted ini December 2019 to January 2020 at Pancoran Kutri springs, Beji Dalem Agung Kemenuh springs and Taman Beji Cengcengan springs. This research aimed to determine water quality based on Bali Governor's Regulation No.16 of 2016 concerning Environmental Quality Standards and Standard Criteria for Enviromental Damage Based on Class (Class I) and Minister of Health Republic of Indonesia Regulation No.492/ Menkes/Per/IV/2010 concerning Prerequisites for Drinking Water Quality. The parameters analyzed were the physical parameters (temperature and TDS), the chemical parameters (pH, DO, BOD, nitrate, phosphate, cadmium (Cd) and lead (Pb)) and the biological parameters (fecal coliform bacteria). The results of the research conducted showed that the water quality in the three springs in the study location still met the water quality standards. However, DO parameters at Pancoran Kutri springs, BOD parameters at Taman Beji Cengcengan springs and phosphate in the three springs at the research location are based on regulations, as well as fecal coliform bacteria parameters in the three springs at the research location based on the Regulation of the Minister of Health of the Republic of Indonesia No. 492/Menkes/Per/IV/2010 have exceeded the quality standard threshold.

This study aimed to determine the effect of juwet fruit extract on histological structure of rat(Rattus sp) trachea which exposed to cigarette smoke. This research used Completely Randomized Design (CRD), with four treatments: the control group (K0) treated with 0.5 % CMC–Na, (K1) group is exposed to cigarette smoke, (K2) group were given juwetfruit extract, and (K3) group is exposed to cigarette smoke and juwet fruit extracts. Each treatment consisted of 6 rats as replication. The exposure to cigarette smoke is given from an aerator pump lit cigarettes. Juwet fruit extract and 0.5 % CMC - Na was orally administered (gavage method) for 48 days. The existence of comperative descriptive observed cilia. And goblet number, high epithelium and lumen diameter Data were analyzed with ANOVA and If they were 5 % significantly different would be followed by Duncan test. Results showed that the extract of the fruit juwet significant effect on the histological structure of the trachea mice that had been exposed to smoke.

Ethanol can damage the liver, indicated by an increase of alanin amino transaminase (ALT) activity and aspartat amino transminase (AST) activity in the blood of alcohol-treated rats. Coffee is rich in antioxidants which are hepatoprotector agent. This study aimed to determine the effect of coffee to reduce alanin amino transaminase (ALT) activity and aspartat amino transminase (AST) activity in blood serum of alcohol-treated rats. The study used 32 male wistar albino rats (200±20g weight) which were divided into four treatment groups i.e. P0 (negative control which were treated with 1 mL of 30% ethanol/200g body weight (bw)/day), P1 (1 mL of 30% ethanol/200 g bw/day + coffee 0,1g/200g bw in 3,5 mL of water/200 g bw/day), P2 (1 mL of 30% ethanol/200g bw + coffee 0,15 g/200g bw in 3,5 mL of water/200g bw/day), dan P3 (1 mL of 30% ethanol/200g bw + coffee 0,2g/200g bw in 3,5 mL of water/200g bw/day). ALT and AST levels were measured by spectrophotometric method. Data analysis was done by ANOVA followed with LSD test and correlation analysis. The results showed that coffee reduced (P<0.01) the activities of ALT and AST of rats blood serum. ALT and AST activities were significantly different (P<0.01) among treatments and with control. Dose of coffee was negatively correlated with ALT activity with correlation coefficient (R) -0.978 and AST with correlation coefficient (R) -0.985 (P<0,01). The lowest of ALT and AST activities were found at dose of coffee 0.2 g/200g body weight. Keywords: ethanol, ALT, AST, coffee

Crop waste or cacao (Theobroma cacao L.) processing waste that doesn’t handle with care can polluting the environment around the farm. Rind of cacao can be used for composting, but it can be less effective because the nutrient of fresh cacao rind too complex and the ratio of C/N too high. This research intention to knows the potential of Aspergillus niger to degrade cellulose on waste cacao rind who have high ratio of C/N, with combination inoculum concentration and incubation time. The methods of this research begin with isolation and identification of A. niger from litter of cacao field, then the in vitro test done by CMCA (Carboxyl Methyl Cellulose Agar) selective media, and then the cacao rind was testing by in vivo method. The results of this research shown that A. niger can degrade cellulose by in vitro ways, it can be seen by the clear zone that formed on CMCA selective media. The in vivo test on cacao rind shown decreasing of C/N ratio between 18,940%-40,623%. Combination of A3B3 treatment (15 mL inoculum concentration, 28 days incubation time) indicate the lowest C/N ratio 18,940%.
