Abstract

Bactrocera dorsalis is a very harmful pest for fruit and vegetable. Chemicalcontrol of these pests has raised another problem. The use of surian leaf extractcan be a good and environmentally friendly alternative control. This study aims to determine the effect of the administration of vegetable pesticides from suren leaf extract in the control of B. dorsalis on red chili. This research had been carried out at Siliwangi University and BBPOPT, Karawang in July to August 2019. This study used a Completely Randomized Design (CRD) with six replications. The concentration of suren leaf extract were : 0%, 0.025%, 0.05%, and 0.1%. The results showed that chili fruit extracts with the highest 0.1% consistently could reduce the number of larvae and the number of fruit attacked. The maincompounds contained in the surian leaf extract include 9,12-Octadecadienoic acid (Z, Z) -, phytol, acetate, phenol, 2-methyl-5- (1,2,2-trimethylcyclopentyl) -, (S) -, Cedren-13-ol, 8-, and 3,7,11,15-Tetramethyl-2-. These compounds were thought to be strong compounds that play a role in suppressing the number of larvae and the number of fruit attacked.

Abstract

Oyster mushroom growing media generally in the form of sawdust. The sawdust contains high levels of cellulose, hemicellulose and lignin so that the C/N ratio is high. Mixing with manure and composting are one way to improve the quality of compost. The purpose of this study was to determine the effect of oyster mushroom waste combined with fermentation time on lettuce growth. The research method used a randomized block design with treatment namely A=oyster mushroom media waste 100% fermented 20 days, B=oyster mushroom waste 100% fermented 25 days C=75% oyster mushroom waste+25% goat manure fermented 20 days, D=75% oyster mushroom waste+25% goat manure fermented 25 days, E=50% oyster mushroom waste+50% goat manure fermented 20 days, F=50% oyster mushroom waste+50% goat manure fermented 25 days, G=25% oyster mushroom waste+75% goat manure fermented 20 days, H=25% oyster mushroom waste+75% goat manure fermented 25 days each treatment was repeated four times. Parameter observed were leaf area, number of leaves, net assimilation rate, root and wet weight ratio per plant. The results showed that a combination of compost consisting of 25% mushroom waste+75% goat manure both fermented 20 days and 25 days had a good influence on leaf area, leaf number, root fission ratio and weight of wet stover per lettuce plant. Keywords: Compost, Fermentation, Lettuce, Organic fertilizer
