This experimental research was aimed at determining the effectiveness of using tuba rootextract (Derris elliptica) on the mortality of caterpillar pests (Lymantria Beatrix) and to find out theoptimum concentration of plant‐based insecticide to reduce Lymantria Beatrix’s activity.The method used in this research included four steps, namely making of extracts, dry time test, thespray test to the leaves (to determine the damage level the leaves caused by pesticides), and testingthe larva of Lymantria Beatrix.The results of this research showed that the tuba root extract (Derris elliptica) could potentially beused as an environment friendly insecticide. Making tuba root extract using maceration process with90% ethanol solvent. Drying time test results for the standard synthetic pesticides, 100%, 75%, 50% and25% extracts, obtained results of 60 minutes, 25 minutes, 29 minutes, 40 minutes and 120 minutesrespectively. While the results of the test spray to the leaves showed that the standard syntheticpesticides causing damages to the side and the top of the leaves looked burnt and the pesticides fromTuba root extract showed the damage was only on the top of leaves that looked burnt after 6 days.Based on the results of the test to the larva of Lymantria Beatrix it could be concluded that theeffectiveness of the extract of the roots of the tuba (Derris elliptica) on the optimum mortality ofcaterpillars (Lymantria Beatrix) at a concentration of 50% with the least damage to leaves and gaveLD50 value of 69.99%.Keywords: tuba root extract, Lymantria beatrix, Botanical insecticide

Abstract

This study was conducted to test the antioxidant content from orange peel powder which was thenused as the material of face mask.The testing method of the antioxidant activity of the orange peel extract used in this study was themethod of DPPH by considering 0.66 gram of the sample which was then added with 10 ml of methanoland messed by using a centrifuge for three minutes. The next step was taking 1.5 ml of filtrate andputting it into a test tube and adding it with 1 ml of DPPH solution. Two samples of solution were made,sample A and sample B. Next, negative control solution was made by mixing 1 ml of sample and 9 ml ofmethanol. The next step was leaving the four kinds of solution in a dark room for 20 minutes. After that,the absorbance (optical density) of the four kinds of solution was measured by using spectrophotometerwith the maximum wave length of 518 nm.Based on the measurement of the data gained, it was revealed that the value of the antioxidantactivity ranged from 66.84% to 68.91%. It indicated that the ornage peel could be used as the materialfor producing face mask.Key words: orange peel, antioxidant, face mask

AbstractThe objective of this research is to ultilize bark waste for tannin‐based adhesive forwood, and polyurethane as additive. It is expected that high tannin content in the bark andpolyurethan additive can support the character of this adhesive.This research followed four steps: 1) finding the problems, 2) identifying the problemsusing the related theory and journal, 3) collecting the data and information, 4) analizing thedata using qualitative data analysis, and 5) finding a conclusion.The result of the research shows that Tannin adhesive has poor adhesive properties,including brittleness, poor wetstrength, and poor wood penetration. This weakness is due toits high reactivity and structural features. To reduce it, the adhesive is modified by addingadditive Poliuretan.Keywords: Bark waste, Tannin adhesive, Polyurethane
