Abstract

Moringa seed oil is a vegetable oil that has many benefits for health and the pharmaceutical industry. Moringa seed oil can be extracted either chemically or mechanically. This research aims to characterize moringa seed oil’s physicochemical properties and fatty acid composition using soxhletation chemical extraction and screw-pressing mechanical extraction with various pretreatment temperatures of 50, 60, and 70°C. The research showed that the highest yield of moringa seed oil, 41.74%, was obtained at an initial treatment temperature of 70°C using the soxhletation method for 6 hours. The acid value of moringa seed oil from soxhletation is 2.01 mg KOH/g, and screw pressing is 4.37 mg KOH/g. The iodine number from soxhletation was 66.62 mg iod/100g, and screw pressing was 60.27 mg iod/100g. The density of the oil from soxhletation and screw pressing is 0.922 mg/mL and 0.934 mg/mL, respectively, with an oil viscosity of 3.298 cP and 3.424 cP. The results of GC-MS analysis show that moringa seed oil from soxhletation has an oleic acid composition of 40.92%, while the screw pressing has an oleic acid composition of 22.50%. This finding demonstrates the influence of extraction methods on the fatty acid profile, particularly the concentration of oleic acid, a key component of moringa seed oil. These results contribute to understanding how specific extraction techniques can optimize the quality of moringa seed oil.

Abstract

The agricultural sector is the backbone of the community's economic activities in general. Not only as a source of food for the people every day, but as a source of foreign exchange for the country as well. Karang Bayan Village, which is located in Lingsar District, West Lombok Regency, is an example of a village with a community that until now still relies on the agricultural sector as a life support. This can be seen from the livelihoods of the people, most of whom work as farmers. The commodities planted by Karang Bayan Village farmers are rice, mangosteen, rambutan and durian. The cultivation of these plants does not always run smoothly, one of the factors is the presence of Plant Pest Organisms (OPT). One way to control pests is to use pesticides on plants. Pesticides consist of 2 types, namely chemical pesticides and natural or vegetable pesticides. One example of a plant that can be used as a pesticide is the papaya plant (Carica papaya). Given that papaya leaves are very easy to find and are not put to good use by the Karang Bayan community, the purpose of this service activity is to provide training and assistance in making natural papaya pesticides in Berembeng Timur Hamlet, Karang Bayan Village, Lingsar District, West Lombok Regency. Pesticide manufacturing activities This natural pesticide program starts on December 27, 2022 until January 24, 2023. This natural pesticide production and training activity aims to provide information and invite the public to be able to make their own natural pesticides so that they can be used to reduce the number of pests such as fleas on cultivated plants, especially in mangosteen plant.
