Abstract

The agricultural sector is one of the main pillars of the economy in Koto Tangah District. Increasing agricultural production requires the support of fertilizer availability in terms of quantity and price. In order to provide fertilizer at competitive prices, fertilizers are needed at low prices and are environmentally friendly. This community service activity is given to the community in Lubuk Minturun Village in the form of training in the manufacture of liquid organic fertilizer (POC) with a fermentation process and extracts of lemongrass. The main ingredient of this fertilizer is rice waste which can be easily collected by local people. The training covers the process of making fertilizer, the fermentation process to packaging. Lemongrass extract is added to increase nutrients in the soil and reduce odors from the fermentation process. The proposing team took this theme in order to provide an alternative for making POCs to the community in Lubuk Minturun Village in the hope of contributing to local flower or fruit plant nurseries. In this case, the proposing team took Lubuk Minturun Village as a model because this area is located close to the ATI Padang Polytechnic Campus, so that it can help the lives of the people around the campus.

Abstract

Bleaching Earth (BE), primarily derived from Bentonite, is widely used in the bleaching process of Crude Palm Oil (CPO). Its efficiency depends on the proportions of SiO₂ and Al₂O₃, which enable effective pigment absorption. This study evaluates the performance of unmodified Bentonite, nano SiO₂-modified Bentonite, and commercial BE in producing Bleached Palm Oil (BPO). The novelty lies in the nano SiO₂ modification, designed to enhance the structural properties and absorption capabilities of Bentonite. Characterization of BE was conducted using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM), while BPO quality was assessed through parameters like moisture content, acid value, Free Fatty Acid (FFA) levels, (Deterioration of Bleachability Index (DOBI), and β-carotene concentration. The results showed that BPO processed with nano SiO₂-modified Bentonite had the lowest β-carotene concentration (443%) and a DOBI value of 1.453, demonstrating superior bleaching performance compared to unmodified and commercial BE. Other parameters, including FFA levels and moisture content, exhibited minimal variation. Color analysis revealed that BPO processed with nano SiO₂-modified Bentonite achieved a comparable color value (1.5/15) to commercial BE. These findings highlight the potential of nano SiO₂-modified bentonite for improving oil quality by reducing FFA and acid value while maintaining optimal moisture content, offering a novel and effective alternative to unmodified bentonite in oil refining.
