Abstract

The decline in the production of oil palm yields in Tomuan Holbung Village,Bandar Pasir Mandoge Subdistrict, Asahan District was identified as a result of a very highlevel of pest infestation. Pests that are often found and becomes the problems are Setothoseaasigna larva. Controlling these pests is a relatively high cost through the application ofchemical synthetic pesticides. The purpose of this research to determine the best formulationof botanical pesticides and their influence in reducing Setothosea asigna larva pests.Botanical pesticides which will be tested in this research are based from garlic, lemongrassleaves, pepper seeds, turmeric, tobacco leaves and papaya leaves. Formulations from eachsource of vegetable material were put into the leaves of palm plants and then tested onSetothosea asigna larva. The parameter observed in this study was the level of palatability ofSetothosea asigna larva. The observations made were based on the level of decrease in thepercentage of feeding activity, the weight of feed (palm oil plant leaves) that were consumedby the Setothosea asigna larva in the period 1-6 days after application. The results of thestudy showed that all treatments of botanical pesticides consisting of: 1) garlic, 2) lemongrass leaves, 3) pepper seeds, 4) turmeric tubers, and 5) tobacco leaves were significantlydifferent from without treatment or control. Then the results of the study also showed that theapplication of botanical pesticides affected the palatability of the Setothosea asigna larva,which accelerated death, appetite and decreased eating activities. The best treatment ofvegetable pesticides from tobacco leaves in controlling the Setothosea asigna larva'spalatability. Setothosea asigna larva die on first day, It don’t want to eat after the applicationof botanical pesticides, and the level of eating activity decreases to 100%.Keywords : Setothosea asigna larva, botanical pesticide, palm plants

Abstract

This study aims to analyze the right combination of charcoal briquette between charcoal from palm stem andcharcoal from cocoa fruit shell waste so that the charcoal briquette results that are appropriate or close to SNI quality standards. Data analysis method in this study used a Completely Randomized Design (CRD) with 5 treatments and 3 replications in each treatment. Comparison between palm stem charcoal and cocoa fruit shell charcoal added with starch adhesive as much as 5% respectively 70%: 30% (P1), 60%: 40% (P2), 50%: 50% (P3) , 40%: 60% (P4) and 30%: 70% (P5). Testing samples in this study include heating value/ calorific value, moisture content, power and combustion efficiency. The result showed that the water content which was found from all the five treatments given had higher water content compared to SNI. The maximum water content of the charcoal briquettes that conforms to SNI is < 8%, so there is no charcoal briquette treatment that matches to SNI criteria. The heat value contained in the charcoal briquettes is greater than the SNI which is > 5000 Kal/ g, so all the five treatments of charcoal briquettes have fulfilled the SNI. While the value of power and efficiency of combustion has not yet been stated in SNI, the power and efficiency of combustion only refers to the lowest average value or briquettes with combustion efficiency that has the longest combustion time used as the best power and efficiency of combustion, so the best quality standard of combustion efficiency is the combination of charcoal briquettes from 70% palm stem and 30% cocoa fruit shell (P1) because it refers to the combustion efficiency of briquettes that have the longest combustion time.
