Abstract

Penelitian ini bertujuan untuk mendapatkan jumlah penambahan ekstrak batang pepaya dalam menghambat pertumbuhan Escherichia coli dan Staphylococcus aureus dalam pembuatan sabun transparan. Penelitian menggunakan rancangan acak lengkap yang terdiri dari 4 perlakuan dan 4 ulangan. Perlakuan dalam penelitian ini adalah batang pepaya ml (P1), penambahan ekstrak batang pepaya 15 ml (P2), penambahan ekstrak batang pepaya 20 ml (P3), penambahan ekstrak batang pepaya 25 ml (P4). Parameter yang diamati adalah kadar air, kadar asam lemak, asam lemak bebas / alkali bebas, pH, stabilitas busa, uji antibakteri dan uji iritasi. Hasil penelitian menunjukkan bahwa penambahan ekstrak batang pepaya berpengaruh nyata terhadap kadar air, kadar asam lemak, asam lemak bebas, pH, stabilitas busa, uji antibakteri dan uji iritasi. Perlakuan yang dipilih dalam penelitian ini adalah perlakuan P3 (penambahan ekstrak batang pepaya 20mg / ml) dengan kadar air 13,24%, asam lemak total 27,00, asam lemak bebas 1,73%, pH, 11,06, stabilitas busa 90,99%, aktivitas antibakteri terhadap S. aureus 8.57 mm dan E.coli 10.33 mm, iritasi erythema 0.05 (hampir tidak terlihat).

Abstract

Biodiesel is the reaction esterification and transesterification between oil and alcohol. Biodiesel raw materials in the form of vegetable oil, one of which is Waste Cooking Oil (WCO). This study aims to obtain the addition of the best methanol in the manufacture of biodiesel from cooking oil. The research method used Randomized Complete Design (RAL) with M1 treatment (methanol 65 ml), M2 (methanol 75 ml), M3 (methanol 85 ml) and M4 (95 ml methanol). The best result was obtained with addition of 95 ml of methanol (M4) with 0.42 mg KOH / g, total glycerol 0,08%, flash point 227 ° C, saponification number 123,46 mg KOH / g and methyl ester 99 , 4%.

Abstract

Durian seeds and jackfruit seeds are agricultural waste containing high starch, which can be used as raw material for biodegradable plastic. The purpose of this research was to get the best formulation on the making of biodegradable plastic based on starch of durian seed and starch of jackfruit seed with addition of beeswax. This research was conducted experimentaly by using complete randomized design (CRD) which consists of five treatments and three replications, thus analysis of variance (ANOVA) and followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatments in this research were P1 (starch of jackfruit seed 5%), P2 (starch of durian seed 1,25% : starch of jackfruit seed 3,75%), P3 (starch of durian seed 2,5% : starch of jackfruit seed 2,5%), P4 (starch of durian seed 3,75% : starch of jackfruit seed 1,25%), and P5 (starch of durian seed 5%) in formulation of biodegradable plastic. The best treatment was P2 which has a thickness of 0,76 mm, water resistance of 59,19%, water vapor transmission rate of 4,53 g/cm2/h, tensile strength of 21,57 MPa, and elongation of 6,58%.
