Abstract

At present it is using digital air measurements using much better analytical functions in the field using digital measurements that have accuracy weaknesses. Developing a condensation device into the air oxygen meter uses two methods: prioritizing Saltzman and Winkler, this corresponds to the contents in the air directly with air and oxygen. Development of atmospheric atmospheric condensation equipment for example ambient air oxygen concentration measuring generator, carried out with the R2D2 development model with a calibration process based on independent sample test Calibration T-test error test with digital titration and electrochemical methods, In addition to the significance of the measurement result is sig value 0.280 > 0, 05 and the calibration measurement results of the tool developed with a digital meter tool obtained the significance of the results that the sig value of 0.254 > 0.05 there was no difference between several samples using the method used.

Abstract

Acne is a kind of disease caused by Propionibacterium acne bacteria. Acne (Acne vulgaris) is a skin disease with chronicle inflammation of follicles polisebacea which generally occurs in adolescence. Treatment commonly used Medicinal Chemicals with high levels that can be harmful to the body. Alternatives that can be used as a substitute for Medicinal Chemicals is medicinal herbal of plant. Plants that can be used as herbal medicines are Kepuh and Jatropha. Kepuh contain triterpenoid, Jatropha contains alkaloid, tannin, saponin and flavonoid. The compounds have the potential as an antibacterial. This research is an experimental research laboratory that uses the diffusion method. Concentration used is 1%, 3%, 5%, 7% and 9%. Based on the results of statistical tests ANOVA difference of Kepuh leaf extract and Jatropha forPropionibacterium acne showed significant differences among treatments with significance value of 0.001. Minimum Inhibitory Concentration (MIC) Kepuh leaf extract that can inhibit the Propionibacterium acne is 3% of 0.7 mm, while the MIC of Jatropha leaves extracts for Propionibacterium acne is 4% of 0.38 mm.

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.

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

The research is a classroom action researched aiming to improved creative thinking skilled and biology learning result by implemented GGE (Group to Group Exchange) learning model with Sequence Chains on students of class X MIPA 4 SMAN 1 Gambiran Banyuwangi academic year 2017/2018 which is done two cycles. Stages cycles includes: planning, action, observation, and reflection. The result of the research of creative thinking skill on pre-cycle is 32,02 increased 43,82 to be 75,85. In learning result, pre cycle cognitive learning comprehensiveness is 43,75% increased 37,5% to be 81,75%, while for effective achievement in the pre-cycle is 36,71 increased 41,58 to be 78,32.

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).
