Alami menunjuk kepada material yang ada dalam makhluk hidup (ciptaan). Semua senyawa yang ada dalam tubuh makhluk hidup dan sintesis oleh peristiwa biokimia merupakan produk organik. Proses perubahan menuju mineralisasi oleh mikroorganisme merupakan peristiwa dekomposisi dan dalam hal ini juga terjadi dalam suatu kehidupan. Selanjutnya, biogeokimia; studi proses-proses biologi pada tanah/lahan merupakan suatu perputaran zat dan hal ini sangat penting dalam kehidupan. (Natural refers to the material that exists in living things (creation). All compounds that exist in the body of living things and are synthesized by biochemical events are organic products. The process of change towards mineralization by microorganisms is a decomposition event and in this case also occurs in a life. Furthermore, biogeochemistry; study of biological processes on soil/land is a cycle of matter and this is very important in life).

Abstract

Fish-Chili- sauce processed by a mixture of cayenne pepper (Capsicum frutescens), tomatoes (Lycopersicum esculentum) and Deles fly fish (Decapterus macrosoma) as fast-food sources of protein that is favored by the public. The purpose of this study are to determine the protein and vitamin C levels of fish-chili-sauce before and after processing. The research method are used completely randomized design with two treatments, namely treatment 1 measured levels of protein and vitamin C before processing; treatment 2 measures the levels of protein and vitamin C after processing. The protein test was performed using the Kjeldahl method with a Spectrophotometer Technique. Vitamin C testing uses the Iodimetry method. The results showed that protein levels of fish before processing = 19.31% and = 20.24 mg/100g of vitamin C. After processing the fish protein content  = 15.63% and = 16.28 mg/100g of vitamin C levels. Decreased fish protein levels and vitamin C levels were thought to be due to the length of processing time. The results of the analysis of the T-Test Pairs showed that there are no significant difference in the protein content of fish-chili-sauce before and after processing, but it tended to decrease. The results of the analysis of the Pairs T-Test showed that there are significant differences in the levels of vitamin C of fish-chili-sauce before and after processing.ABSTRAKSambal-ikan hasil olahan campuran cabai rawit (Capsicum frutescens), tomat (Lycopersicum esculentum) dan ikan layang Deles (Decapterus macrosoma) sebagai sumber protein cepat saji yang digemari oleh masyarakat.

Abstract

Natural insecticides made from lemongrass plants and zodia which are environmentally friendly insecticides and contribute to mosquito mortality. The purpose of this study was to determine the effect of lemongrass insecticides  (Cymbopogon nardus) and leaves of zodiac (Evodia suaveolens) on mosquito mortality (Aedes aegypti), and to determine the treatment of insecticides that were more effective against the mortality of mosquitoes. The research method used the experimental completely randomized design (CRD) with 4 treatments and 5 replications, namely treatment 1 control; treatment of 2 insecticides zodia; treatment of 3 lemongrass insecticides; and treatment of 4 combination lemongrass insecticides and zodia. The results showed that the control treatment did not effect, whereas in the treatment of zodia insecticides, lemongrass and combinations there were influences, presumably this happened because of difference in the chemical compounds of the 2 plants against mosquitoes. The results showed that mosquito mortality was controlled by 0%; mosquito mortality with zodia insecticide of 28%; mosquito mortality with lemongrass insecticide of 16.4%; and mosquito mortality with combination lemongrass insecticides and zodiac of 43.2%. The results of the One Way ANOVA test showed that there were significant differences and tended to experience increased mosquito mortality after being treated. Insecticides that are more effective in causing mosquito mortality are combination insecticides of lemongrass and zodia leaves.Keywords: Vegetable Insecticides, Lemongrass Plants, Zodia Plants, Mosquitoes.ABSTRAKInsektisida alami yang terbuat dari tanaman serai dan zodia merupakan insektisida alami yang ramah lingkungan dan berperan terhadap mortalitas nyamuk. Tujuan dari penelitian ini untuk mengetahui pengaruh insektisida serai (Cymbopogon nardus) dan daun zodia (Evodia suaveolens) terhadap mortalitas nyamuk (Aedes aegypti) dan untuk mengetahui perlakuan insektisida yang lebih efektif terhadap mortalitas nyamuk (Aedes aegypti). Metode penelitian menggunkan eksperimental Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan yaitu perlakuan 1 kontrol; perlakuan 2 insektisida zodia; perlakuan 3 insektisida serai; dan perlakuan 4 insektisida kombinasi serai dan zodia. Hasil penelitian menunjukkan perlakuan kontrol tidak ada pengaruh terhadap mortalitas nyamuk, sedangkan pada perlakuan insektisida zodia, serai serta kombinasi terdapat pengaruh, diduga hal tersebut terjadi karena adanya perbedaan kandungan senyawa kimia dari 2 tanaman tersebut terhadap nyamuk. Hasil penelitian menunjukkan mortalitas nyamuk perlakuan kontrol 0%; mortalitas nyamuk dengan insektisida zodia 28%; mortalitas nyamuk dengan insektisida serai 16,4%; dan mortalitas nyamuk dengan insektisida kombinasi serai dan zodia 43,2%.
