Abstract

Cashew nut skin is considered as waste, whereas cashew nutshell extract, or called CNSL (Cashew Nut Shell Liquid), has the potential as a botanical insecticide that can control insect pests. Helopeltis sp is a pest that often attacks cacao plants. The study aims to determine the effectiveness of cashew nutshell extract as a botanical insecticide to control  Helopeltis sp. in cacao plants. The study used a randomized block design (RBD) with seven treatments and three replications. Testing CNSL on adult (imago) and pre-adult (nymph) insects. CNSL concentrations used are 0%, 3.125%, 6.25%, 12.5%, 25%, 50% and 100%. The results showed that cashew nutshell extract has strong toxicity. A concentration of 3.125% can kill 100% of the imago Helopeltis sp. (72 hours after application) for the nymph Helopeltis sp. (48 hours after application). LC50 values 24 hours after application for imago and nymph were 4.63% and 0.94%, and LC99 for imago and nymph was 42.62% and 23.89%.  Furthermore,  cashew nut extract can be used as a botanical insecticide to control other plant pests.

Abstract

Corn (Zea mays) has various health benefits derived from its carotenoid content, which gives its kernels their yellow color. Approximately 22% of this content is beta-carotene, which functions to prevent blindness due to cataracts, while xanthophyll protects cells from cancer, acts as an antioxidant, and supports the immune system and heart health. This community service activity aims to increase understanding of the optimal use of corn, specifically through the production of nutritious twistcorn snacks. This training involved the community in RT.001 RW.003 Laren Village and began with an initial questionnaire, followed by the delivery of materials on making twist corn snacks, and concluded with a final questionnaire. The material was delivered through lectures and question-and-answer discussions, which were met with enthusiasm by the participants. The results of the activity demonstrated an increase in knowledge among all participating communities following the training. Jagung (Zea mays) memiliki berbagai manfaat kesehatan yang berasal dari kandungan karotenoidnya, yang memberikan warna kuning pada bijinya.

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman tentang pemanfaatan jagung secara optimal, khususnya melalui pembuatan snack jagung twistcorn yang bergizi. Pelatihan ini melibatkan masyarakat di RT.001 RW.003 Desa Laren dan dimulai dengan kuisioner awal, diikuti dengan penyampaian materi mengenai pembuatan camilan jagung twistcorn, dan diakhiri dengan kuisioner akhir.
