Abstract

This study was aimed at determining the activity of Marsh Fleabane leaves extract against Aedes aegypti mosquito larvae mortality. Marsh Fleabane leaves extract was obtained using ethanol solvent. After obtaining the viscous extract, the extract was fractionated with solvent n-hexan and ethyl acetate. The ability of this biolarvaside was determined by LC50 value and reinforced by identifying of active compound content. This biolarvaside test was conducted on Aedes aegypti mosquito larvae with variation of extract concentration 50, 100, 250, 500, and 1000 ppm during 24 hours observation. Identification of compound content was done by testing the sample with GC-MS analysis. The results show that the yield of ethyl acetate extract equal to 1.86%. The LC value of this ethyl acetate extract was 105.79 ppm. The obtained LC50 values including active biolarvacidal groups and positive controls using abate had LC100 values at 100 ppm concentrations. Meanwhile, the LC50 value on granules using marsh Fleabane leaves extract content was obtained at 96.34ppm and LC90 was 905.1 ppm. The ability of active biolarvaside is corroborated by GC-MS analysis results indicating that the biolarvacid content of active compounds contained in ethyl acetate extract expected as quinic acid

Abstract

Biolubricant dibuat dengan mereaksikan minyak nabati dengan alkohol dengan bantuan asam kuat atau katalis basa kuat dalam proses esterifikasi. Tujuan dari penelitian ini adalah untuk mengetahui titik nyala dari biolubricant, dan mengetahui karakteristiknya. Penelitian ini dilakukan dengan mereaksikan minyak jarak dan reaktan metanol dengan asam perklorat dengan variasi mol reaktan dan variasi konsentrasi asam perklorat sebagai katalis dengan waktu esterifikasi 7 jam, setelah itu akan dimurnikan dengan berbagai metode untuk mendapatkan hasil yang diinginkan. Hasil dalam penelitian ini memiliki titik nyala tertinggi pada 268 oC dan terendah pada 242 oC; viskositas tertinggi pada 217 cP dan terendah pada 130,5 cP pada 40 oC. Pada suhu lain, viskositas terbaik adalah 184,5 cP pada 40 oC dan 27,45 cP pada 100 oC. Titik tuang rata-rata dari biolubricant ini adalah -18,8 oC. Senyawa kimia Biolubricant hampir mengandung asam lemak 9,12-Octadecadienoic acid (Z, Z) dengan methanol yang menghasilkan senyawa mono-ester 9-Octadecenoic acid (Z) -, 2-hydrox y-1- (hydroxymethyl) ethyl ester.

Abstract

The waste problem was one of the priorities of the local government. The waste sorting business started from the beginning, but the management and reprocessing of waste was a separate homework from the Environment Agency. The Untirta Community Service Team offered the processing of organik waste into Liquid Organik Fertilizer (POC) through a fermentation process with the used of EM4. The fermentation process for 7-15 days produced POC which has essential nutrients needed by plants. Giving 1:1 POC to plants increased more fruit and increased color brightness in ornamental plants. Socialization and training activities were carried out in 2 farmer groups in Pandeglang Regency. Direct practice of making POCs and the team giving POCs to participants so that they can be applied directly in their respective places. The socialization activities were supported by the village government and support from the Pandeglang Regency Agricultural Extension Center.
