Abstract

Kelurahan Buluminung is one of the villages in Penajam Sub-district, Penajam Paser Utara Regency. This village has several problems, one of which is the absence of temporary shelters (TPS) and final processing sites in the Muan area (RT 2 to RT 6). The purpose of this activity is to overcome organic waste that is easily degraded by applying biopore infiltration holes in planting fruit plants. The method used in this activity is divided into two, namely direct practice in the field (applied) and socialization. The applied part consists of several stages, namely the layout of land facilities, soil pH measurement, making biopore infiltration holes, selecting fruit plant seeds, planting fruit plants, and installing SOPs for the utilization of biopore infiltration holes. After that, socialization was carried out to show the results of practice directly in the field. This socialization activity was divided into three main materials, namely 1) Biopori, 2) Fruit Planting, and 3) Fruit Plant Care. The results obtained from this activity are the implementation of direct practice in the field and socialization of the use of biopore infiltration holes in planting fruit plants in the general public of Buluminung village. There were people who managed to make biopore infiltration holes and apply them in their yard after the implementation of this activity.

Abstract

Cooking oil has a primary function as a heat transfer medium in food processing. Repeated use of cooking oil can reduce its quality, which is often referred to as used cooking oil. Many people use cooking oil repeatedly to save money without considering the impact. The purpose of this study was to determine the results of refining used cooking oil in terms of free fatty acid (FFA) levels through the adsorption method using calcined ash from several different types of adsorbents, namely chicken eggshells, Tegillarca granosa shells, zeolite, and bricks. Based on the results of the study, the results of the FFA content of the used cooking oil sample were 2.735%. The results of the FFA content of the used cooking oil sample after being adsorbed using calcined ash from chicken eggshells, blood cockle shells, zeolite, and bricks were 0.638%, 0.464%, 1.691%, and 0.921%, respectively. Of the four adsorbent materials, the type of adsorbent obtained is calcined blood cockle shell ash which is the most effective in reducing the ALB levels of used cooking oil samples, which is 83.03%. Then followed by chicken egg shells, which is 76.67%, bricks, which is 66.32%, and commercial zeolite, which is 38.17%.
