Abstract

The purpose of this research is to measure Linoleic Acid and Linolenic Acid Level in Tofu and Fermented Soybean Cake through Gas Chromatography-Mass Spectrometry. This is a laboratory research that use tofu and fermented soybean cake from Telaga traditional market as the sample of research. Sample was extracted by using n-hexane to produce oil. Then, oil was hydrolyzed by using KOH liquid and H2SO4 as a catalyst to get the free fatty acid. Then, it was converted to metil ester by using CH3OH as a solvent and H2SO4 as a catalyst for the necessity of fatty acid analysis. This research used Gas Chromatography-Mass Spectrometry to identify Linoleic Acid and Linolenic Acid Level in the sample. The analysis result shows that the biggest component of metil ester in tofu and soybean cake are dominated by metil linoleic (metil 9.12-octadekadienoat) with percentage 55.25% and 27.08% for each. Mean, the linolenic acid in tofu and fermented soybean cake cannot be detected by GC-MS. It is caused by the fermentation time, high temperature during production and fermentation, and humidity in the sample. Therefore, a further research is necessary to investigate level of linolenic acid. In tofu and fermented soybean cake.

Abstract

KKN MBKM (Kuliah Karya Nyata Merdeka Belajar Kampus Merdeka) is a form of education that provides learning experiences for students to live in the community outside the campus and directly identify community potential and deal with problems so that they are expected to be able to develop the potential of villages and regions and gather solutions to problems that exist in the village. Real Work Lectures at this time coincide with the COVID-19 pandemic, so it has implications for governance differences with normal times. Various work programs have been planned before going to the KKN location, including the manufacture of hydroponic media and aquaponics, making hand sanitizer using natural materials, making Pone's food, and the implementation of tutoring to increase interest in learning from children who have been studying online for a long time. The results of this study show that community service program activities as a form of community service during the pandemic are still ongoing. The community can still feel the benefits, and the role of students can still be carried out with a series of innovative activities as well as continuing to follow health protocols.

Abstract

The purpose of this study was to determine and analyze the levels of leadcontained in the water and sediments of the Rumbia River. This research was conducted in a quantitative manner. Lead levels were measured using Atomic Absorption Spectrophotometer (SSA) of Simatzu AA 500. The results showed that the leadcontent in Rumbia River water for point A1 was undetectable whereas point 2 and 3 were 0.001 mg/kg. In sediments, at point A1 is 1.8 mg/kg and at points 2 and 3 were 0.9 mg/kg. The level of Pb in Rumbia River water is still below the water quality standard limit for marine biota determined by the Ministry of Environment No. 51 of 2004. Similarly, lead levels in sediments are below the threshold standard for sediment quality based on sediment quality guidelines for metals and associated levels of concern to be used in doing assessments of sediment quality. In general, it can be said that the concentration of lead in the Rumbia River is still at a harmless level. However, socio-economic conditions that continue to change over time can cause changes in the level of water pollution. So there needs to be an effort and public awareness in maintaining the occurrence of increased levels of pollutants in the Rumbia River.

Abstract

Kesejahteraan merupakan salah satu hal yang diidam-idamkan oleh masyarakat, terlebih masyarakat pesisir yang ada di Desa Tayadun dan Desa Bukamog Kecamata Bokat Kabupaten Buol yang notabene belum tercapai. Jagung merupakan salah satu tanaman yang banyak ditanam di Indonesia. Dari setiap panen jagung diperkirakan jagung (rendemen) yang dihasilkan sekitar 65%, sementara 35% dalam bentuk limbah berupa batang, daun, kulit, dan tongkol jagung. Dari pengamatan lapangan ditemukan bahwa hasil samping berupa kulit, batang, daun, dan tongkol jagung tidak termanfaatkan dan dibuang atau dibakar, sementara daun dan batang yang masih muda dijadikan bahan pakan ternak. Pemanfaatan limbah tongkol jagung menjadi briket dapat dilaksanakan dengan baik sampai dengan pelaksaan aplikasi pada masyarakat. Dengan berhasilnya kegiatan ini, diharapkan apa yang telah dirintis oleh mahasiswa KKN Tematik tahun 2022 ini bias belanjut terus hingga suatu hari nanti masyarakat desa Bukamog dan Tayadun bisa melakukan ekspor ke luarg daerah bahkan luar negeri, terlebih saat ini di desa Tayadun terdapat 2 orang peserta pelatihan yang sudah memiliki usaha pembuatan arang dari tempurung kelapa.

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
