Abstract

Using cooking oil repeatedly will have an impact on health. Cooking oil repeatedly changes color to a darker color, produces an unpleasant odor, and has high levels of fatty acids. Cooking oil experiences changes due to the chemical properties of cooking oil, such as a reaction where the color changes to brown when cooking oil is used at high temperatures by reacting with air. Therefore, it is necessary to purify used cooking oil to be used as a material that is more beneficial to society. The utilization of cocoa shell waste into carbon that has been processed is used for the adsorption process of purification of used cooking oil. The process of purifying used cooking oil begins with making activated charcoal, chemical activation of activated charcoal with hydrochloric acid (HCl), assembling appropriate technology for oil purification, adsorption process of used cooking oil which goes through several stages of purification, namely zeolite stone, cotton, cocoa charcoal, cotton and filter cloth. , and the process of using purified used cooking oil into aromatherapy candles. The materials used in making candles are paraffin and used cooking oil in a 1:1 ratio. Candles are packaged attractively to provide consumers and add selling value. This activity attracted the enthusiasm of the community to utilize used cooking oil into aroma therapy candles. In addition, the Panti Village Tourism Awareness Group is interested in utilizing used cooking oil to make souvenir aroma therapy candles at Panti village tourist attractions.It is hoped that using used cooking oil that has been purified into aromatherapy candles will become a source of income for the people of Kedaton Plantation, reducing waste disposal so that the environment will be better protected.

Abstract

Mikroplastik diartikan sebagai plastik yang berukuran kurang dari 5 mm. Mikroplastik telah terdeteksi secara luas di lingkungan perairan dan menjadi kontaminan yang sangat mengkhawatirkan. Oleh karena itu sangat diperlukan cara untuk menghilangkan mikroplastik dari air secara efektif. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh penambahan surfaktan asam oleat (OA) dan polietilen glikol (PEG) pada nanopartikel magnetit untuk pemisahan mikroplastik polyethylene terephthalate (PET) di media air. Penambahan surfaktan memungkinkan nanopartikel dapat terdispersi dengan baik dan lebih stabil. Nanopartikel magnetit disintesis dari pasir besi pantai Watu Ulo Jember dengan metode co-precipitation. Nanopartikel magnetit dikarakterisasi menggunakan PSA untuk mengetahui distribusi ukuran partikel dan FTIR untuk menentukan gugus fungsi pada n-Fe3O4 yang telah dimodifikasi dengan OA dan PEG. Ukuran partikel yang didapatkan berkisar antara 458,7–955,4 nm dengan intensitas tertinggi 712,4 nm. Efisiensi adsorpsi mikroplastik yang diperoleh menggunakan n-Fe3O4 adalah 77,8%, n-Fe3O4/PEG 91,7%, dan n- Fe3O4/OA 95,2%.
