Pestisida organik adalah pestisida yang bahan dasarnya berasal dari tumbuhan yang bersifat mudah terurai di alam. Salah satu tumbuhan yang dapat dijadikan bahan baku pembuatan pestisida organik adalah kulit jeruk nipis. Kulit jeruk dapat berpotensi menjadi repellent karena mengandung minyak atsiri dengan komponen limonene, mirsen, linalool, oktanal, decanal, sitronelol, neral, geraniol, valensen dan sinensial. Linalool, sitronelol dan geraniol termasuk senyawa yang bersifat repellent terhadap serangga (arthropoda).  Pengunaan bahan alami dari ekstrak kulit jeruk diharapkan lebih aman jika dibandingkan dengan bahan kimia Dichloro Diphenyl Trichloroethane (DDT). Proses pembuatan pestisida organik dilakukan dengan ekstraksi maserasi menggunakan ethanol sebagai pelarut. Dalam penelitian ini bertujuan untuk mengetahui pengaruh variabel terhadap hasil pengujian pestisida organic terhadap jangkrik. Hasil penelitian menunjukkan pada konsentrasi pestisida organic 5% didapatkan prosentase kematian jangkrik 72%, pada konsentrasi 15% didapatkan prosen kematian jangkrik 80%, dan pada konsentrasi 25% didapatkan prosen kematian jangkrik 88%. Hasil penelitian menunjukkan bahwa adanya pengaruh terhadap perbedaan konsentrasi pestisida organic terhadap kematian jangkrik. Kata kunci: jeruk nipis, maserasi, pestisida organik AbstractOrganic pesticides are pesticides whose basic ingredients come from plants that are easily biodegradable in nature. One of the plants that can be used as raw material for making organic pesticides is lime peel. Orange peel can potentially be a repellent because it contains essential oils with components of limonene, mirsen, linalool, octanal, decanal, citronellol, neral, geraniol, valensen and sinensial. Linalool, citronellol and geraniol are compounds that are repellent to insects (arthropoda). The use of natural ingredients from orange peel extract is expected to be safer when compared to the chemical Dichloro Diphenyl Trichloroethane (DDT). The process of making organic pesticides is done by maceration extraction using ethanol as a solvent. This study aims to determine the effect of variables on the results of testing organic pesticides on crickets. The results showed that at 5% organic pesticide concentration, 72% of crickets died, at 15%, 80% of crickets died, and at 25%, 88% of crickets died. The results showed that there was an effect on differences in the concentration of organic pesticides on the mortality of crickets.. Keywords: lime, maceration, organic pesticide

Abstract The aim of the present study was to evaluate antioxidative activities of the encapsulated and unencapsulated bitter orange peel extract on the shelf-life of the common carp fillets during 16 days of refrigerated storage. Common carp fillets were treated with bitter orange peel extract (0.5 and 1% w/w), liposomal encapsulated bitter orange peel extract (0.5 and 1% w/w) and beta-hydroxytoluene (BHT, 100 and 200 ppm); their quality changes in terms of total volatile basic nitrogen (TVB-N), free fatty acid (FFA) peroxide value (PV), thiobarbituric acid (TBA) and sensory characteristics were investigated. Results showed that the encapsulated and pure extract and BHT could reduce chemical deterioration and lipid oxidation in the fillets compared to the control, as reflected with lower TVBN, FFA, PV and TBA values. Furthermore, common carp fillets treated with high concentration (1%) of the encapsulated bitter orange peel extract showed the lowest amount of lipid oxidation during the storage period compared with the others without any undesirable changes in sensorial attributes.
