Abstract

Pengolahan hasil tambang pada Usaha Kecil Menengah (UKM) pertambangan memiliki banyak permasalahan, baik yang bersifat teknis maupun non teknis. Pada kegiatan Pengabdian kepada Masyarakat (PkM) kali ini berfokus pada permasalahan teknis, yakni membantu optimalisasi variabel operasi peralatan flotasi yang merupakan unit produksi penting dari UKM pertambangan. Permasalahan dalam optimasi variabel flotasi memberikan kemanfaatan bagi kedua belah pihak, baik UKM pertambangan dan Prodi Teknik Pertambangan Universitas Trisakti. Untuk pihak UKM bisa memanfaatkan alat batch flotation yang dimiliki laboratorium Teknik Pertambangan Universitas Trisakti dan mendapatkan data-data optimalisasi variabel flotasi, sedangkan bagi prodi akan mendapatkan informasi yang lebih akurat, terkait target apa saja yang diperlukan UKM pertambangan khususnya pada recovery dan kadar konsentrat. Tujuan PkM ini adalah membangun kerjasama yang bermanfaat pada kedua belah pihak, khususnya terkait bidang pengolahan pada pertambangan skala kecil-menengah, yakni optimasi variabel flotasi dengan metode batch flotation. Metode yang digunakan pada kegiatan PkM “Optimasi Flotasi Tambang Usaha Kecil Menengah dengan Metode Batch flotation” adalah pelatihan yang dilakukan di laboratorium Pengolahan Bahan Galian (PBG) Prodi Teknik Pertambangan, Fakultas Teknologi Kebumian dan Energi, Universitas Trisakti dengan penyuluhan (sosialisasi) melalui media daring (Zoom Meeting). Hasil PkM bagi UKM pertambangan adalah karyawan dapat lebih memahami optimasi variabel flotasi dengan metode batch flotation.

Abstract

Used cooking oil is an oil that has been used repeatedly in the process of frying food. Repeated use of cooking oil will cause a decrease in the quality of used cooking oil and if consumed will be harmful to health. The decrease in the quality of used cooking oil due to the formation of more double bonds in the structure of used cooking oil causes the oil to be more easily oxidized. The oxidation experienced by used cooking oil causes the quality of used cooking oil to decrease marked by the increasing value of peroxide number, free fatty acid content, water content and acid number of used cooking oil. One of the efforts that can be done to improve the quality of used cooking oil is to add an adsorbent to the used cooking oil. The added adsorbent serves to adsorb the impurities contained in the used cooking oil. One of the adsorbents that can be used is zeolite, zeolite can be used as an adsorbent because of the wide surface area of ​​zeolite which makes it easier for zeolite to adsorb chemical compounds on its surface. To test the quality of the oil can be done by measuring the peroxide number, free fatty acid content, water content and acid number. In this community service, training activities for refining used cooking oil will be carried out to the people of the Tanjung Gedong area, Tomang, West Jakarta. The link between PkM training in refining used cooking oil using natural zeolite for residents of the Tanjung Gedong area, West Jakarta and PkM flagship usakti, namely in the areas of regional development, ecogreen, and alternative energy. Namely using natural materials such as zeolite which is environmentally friendly to improve the quality of used cooking oil.
