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. Based on the above explanation, it can be concluded that the implementation of GGE (Group to Group Exchange) with Sequence Chains can improve creative thinking skill and learning result of students class X MIPA 4 SMAN 1 Gambiran Banyuwangi academic year 2017/2018.

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).

Abstract

Solar water heater (SWH) merupakan salah satu teknologi dalam pemanfaatan energi matahari. Pada penelitian ini phase change material (PCM) diaplikasikan untuk meningkatkan kapasitas penyimpanan panas solar water heater (SWH). PCM menerima panas sensibel dan panas laten hingga mencapai titik pelelehan. Tujuan dari penelitian ini adalah mengetahui karakteristik PCM (waktu pelelehan, kontur pelelehan, heat transfer, panas kumulatif) selama proses charging. Pemodelan simulasi dilakukan menggunakan metode enthalpy-porosity dengan memvariasikan susunan peletakan kapsul menjadi inline, staggered, dan crossline. Jenis PCM yang digunakan adalah paraffin wax RT52. Heat flux dan debit aliran air dijaga tetap sebesar 1000 W/m2 dan 1 lpm. Hasil simulasi menunjukkan variasi inline, staggered dan crossline menyebabkan perbedaan waktu pelelehan 6,8%, heat transfer tertinggi 12,9% , dan panas kumulatif sebesar 8%.
