Ngapi nut peel is an organic waste that is often found at traditional markets which has not been fully utilized and can pollute the environment. The utilization of ngapi nut peel extract to control stink bugs was carried out. The purpose of this study was to obtain LC50 values and compounds that can eradicate stink bugs. Ngapi nut peel was extracted with methanol using the maceration method, the extract were analyzed by using GC-MS, phytochemical test was used to determine secondary metabolite and total phenolic by using the Follin-Ciocalteau method. The spray method was used to determined LC50 on stink bugs. The results showed that methanol extract positively contained flavonoid, phenolic, saponin and terpenoid. Total phenolic value was 0.65 mg GAE/g DW. GC-MS showed compounds that have the potential as natural pesticides such as 2,4-Dimethyl-6-phenyl-1,3,5-triazine; 3-(4-Methoxypheny l,2-propenoic acid; Undecanoic acid; Phthalic acid. LC50 test for 12 and 24 hours were found on concentrations 24.4174 g/L and 17.3101 g/L. The methanol extract of ngapi nut peel on concentrations of 35 g/L showed the highest percentage 87% of stink bugs mortality at 24 hours. It can be concluded that extract can control the stink bugs.
