Abstract

Indonesia is the 2nd largest country in the world in terms of palm oil production. The demand for Crude Palm Oil increases every year. For this reason, Indonesia is expected to be able to compete at the international industry level in producing palm oil, with the aim of being able to produce good quality palm oil among industries in other countries. The problem that often occurs in CPO factories is a decrease in the quality of CPO caused by an increase in Free Fatty Acid (FFA) levels and Peroxide Numbers. Antioxidants are substances that can delay or prevent the occurrence of free radical anti-oxidation reactions in the oxidation of fats or oils. Natural antioxidants are antioxidants that are obtained directly from nature. Natural antioxidants are antioxidants that are obtained directly from nature. One of them is the leaf of the matoa plant (Pometia pinnata). Based on the results of this study, the antioxidants of the ethanol extract of the matoa plant can reduce levels of FFA and peroxide numbers depending on the length of time the antioxidant mixture is given to CPO. In this study, a decrease in FFA levels and peroxide numbers was obtained from samples on day - 10 with the addition of 5000 ppm antioxidants, namely 2.71%. while the peroxide number is 0.83%.

Abstract

This research aims to determine the chemical characteristics of coconut shell liquid smoke and analyze the effectiveness of using liquid smoke in reducing Pb metal contamination in skipjack tuna (Katsuwonus Pelamis). Grade 2 liquid smoke from coconut shells is produced by the Pulubala IKM center through the stages of pyrolysis and distillation. This study employs a completely randomized design (CRD) with two replications. To determine the chemical characteristics of the liquid smoke, the analyzed methods include pH measurement, phenol content, total acidity, protein content, organoleptic value, and the chelating power of heavy metal Pb with variations in the concentration of liquid smoke test solutions AC (undiluted liquid smoke), AC2, AC4, AC6, and AC10 (liquid smoke with the addition of distilled water at 2%, 4%, 6%, and 10%). The results show that the best treatment is obtained from coconut shell liquid smoke with AC concentration (undiluted liquid smoke) having the best characteristics, namely a pH value of 4, phenol content of 1.6469%, total acidity of 14.94 mg/mL, protein content of 0.6083%, and a chelating power for heavy metal Pb of 97.32%. The results of the organoleptic test indicate that overall, the highest score was obtained with a neutral value at the concentration of AC2 (liquid smoke with the addition of 2% distilled water).

Abstract

This service activity aims to provide training on making vegetable pesticides to farmers and housewives. As an alternative to controlling plant insect pests, the use of vegetable pesticides is considered safe to use. Botanical Pesticides are pesticides whose active ingredients come from plants or herbs and other organic materials which are efficacious in controlling pest attacks on plants. This pesticide does not leave harmful residues on plants or the environment and can be made easily using inexpensive materials and simple equipment. Vegetable pesticides are relatively easy to make with natural or vegetable ingredients which make these pesticides easy to decompose in nature so they don't pollute the environment. This organic pesticide is able to overcome and repel pests that destroy agricultural and plantation crops in general, such as fleas, caterpillars, grasshoppers and so on. The method used is direct training to groups of housewives and vegetable farmers using innovative technology. From the results of the implementation of these activities, the community was very enthusiastic about participating in these activities and was interested in making/producing their own pesticides from materials that are easy to obtain from the surrounding environment
