Abstract: Uric acid is the final substance of purine breakdown which is assisted by guanase and xanthine oxidase enzymes. Excess blood uric acid levels are called hyperurosemia. Treatment is usually using synthetic drugs such as allopurinol which has side effects for the body, so it is necessary to take herbal remedies such as Syzygium polyanthum Wight which contains active ingredients such as flavonoids as an inhibitor of the xanthine oxidase enzyme. This study aims to determine the effect of giving Salam Leaf Decoction to the Decrease in Blood Uric Acid Levels. This study uses a completely randomized design study (CRD) with 5 repetitions. This study uses One Way Anova data analysis and continued with Duncan's Test. From the results of the study, at a dose of P1 (0.2 ml / 20 g WB), P2 (0.4 ml / 20 g WB) and P3 (0.8 ml / 20 g BB), a percentage of uric acid levels decreased 40.45% in group P1; 48.19% in the P2 group; 53.53% in the P3 group; 60.35% in the K + group; and -30.73% in the K-group. Of the 5 doses, the most effective dose to reduce uric acid levels in the blood is P2 dose (0.4 ml / 20g WB). KeyWords: Salam Leaf; Hyperurosemia Reduction;uric.

Abstract: Critical thinking skills are included in high-level thinking skills that train students to think logically, scientifically, and are relevant in solving problems. These skills need to be applied in the learning of the modern era today, one of which is PBL-based TPS learning that has the thinking syntax of thinking, grouping, and sharing opinions, combined with a problem-based approach. This study aims to determine the effect of Think Pair Share (TPS) learning models based on the Problem Based Learning (PBL) approach to critical thinking skills and students' biology learning outcomes. The population in this study were students of class XI MIPA at Balung Jember High School in the academic year 2017/2018. The research sample was class XI MIPA 2 as the experimental class and class XI MIPA 1 as the control class. The results showed that the Think Pair Share learning model based on the Problem Based Learning approach had a significant effect on critical thinking skills with a significance of (p = 0,000) and was also able to improve students' biology learning outcomes in the cognitive, affective and psychomotor domains. Keywords: critical thinking skills; Think Pair Share; problem-based approach.

Abstract: The majority of Indonesian coffee production is robusta coffee. The increasing coffee production with large scale causes changes in the soil ecosystem, it profitable for development of pest populations and diseases in coffee. One of pests that attack coffee plant is Pratylenchus coffeae. Rizosphere is ground around the roots measuring about 1 mm and surrounds entire surface of roots. Rizobacteria are beneficial bacteria that live in a saprophyte in a rhizosphere. This research aims to perform the isolation and identification of rhizobacteria from robusta coffee plants in Kali Bendo plantation, Banyuwangi Regency, East Java. In this research, the determination of research location is using purposive sampling technique, while the sampling technique is using random sampling method. The results showed there were 8 isolates obtained Bacillus sp. with isolate code 3R, G20, and I13, Micrococcus sp. with isolate code L20, Acinetobacter sp. with isolate code 4R and C13 and Pseudomonas sp. with isolate code M20 and A13.

Abstract: Avocado leaves (Persea americana Mill.) historically used as a herbal medicine used to ease the expense of urine and crushed a kidney stone in the urinary tract. Avocado leaves contain sugar, d-parseit, quercetin, flavonoids, and compounds sterin. The availability of avocado leaves in the society becames a great opportunity to be utilized as a herbal medicine, it is unknown yet whether the avocado leaves extract was able to decrease edema glomerulus and cell damage in the kidneys. The aim of this research knew the effect of ethanol extract of avocado leaves to decrease edema glomerulus and cell damage kidney of white rat. The research method used The Post Test Only Control Group Design. The dose was 100 mg/0.2kg bw, 200 mg/0.2kg bw, 300 mg/0.2kg bw, with inducer (ethylene glycol + ammonium chloride) as positive control, the treatment carried out during 10 days. Data analysis used Anova. The results showed for parameter damage the glomerulus with (F = 4.931, p = 0.027, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease edema glomerulus, while parameters proximal tubule damage with (F = 5.755, p = 0.018, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease cell damage kidney white rat. The dose of ethanol extract of avocado leaves which are most effective against the decrease of edema glomerulus was 100 mg/0.2kg bw and cell damage kidney white rat was 200 mg/0.2kg bw.

Abstract: In indonesia, infection diseases are a very high problem among the public, one the common infectious diseases suffered by the Indonesian community is imflamtion of the tonsils caused by Streptococcus pyogenesis and Cholera caused by Vibrio cholera. The use of chemical antibiotics will have a negative impact in health, so necessary alternative replecement of natural antibiotics by Serratia mercescens can pruduce prodigiosin. This reseacrh was to test the potential of Serratia mercescens antagonist against Streptococcus phyogenesis and Vibrio cholera in vitro, using Completely Randomized Design with one treatment factor from Serratia mercescens bacteria concentration. The concentration used was 30μm for each bacterial suspension and added positive control in the form of chloramphenicol and negative control of aquades, each of which was repeated 3 repititions. The results were analyzed using one-way ANOVA and continued D- test. The result showed that Serratia mercescens had blocked inhibitability of Streptococcus phyogenesis bacteria with an average resistance of1.1033mm and on Vibrio cholera with an average resistance of 1.2233mm.
