Abstract

Like as the fish processing industry in general, the traditional processing industry also has a significant environmental impact. This community service was aimed to provide counselling related to environmental health management to a group of “pemindang” at central “pemindangan” industry Kusamba. The material provided is in the form of the benefit and importance of personal hygiene and environmental sanitation in fish processing, especially pindang, demonstration and exercise of 7 steps of hand washing, socialization on the use of personal protective equipment (PPE) and eco enzyme based on orange peel waste, and provision in providing garbage containers to improve environmental sanitation in the area of “pemindangan”. The participants had high enthusiasm in following the activities and from 10 participants who took the posttest, all of participants received score > 70. This empowerment activities are expected to be able to increase the knowledge of the group of “pemindang” on the importance of environmental health for fish processing industry, including “pemindangan” industry.

Abstract

This study aims to analyze the antioxidant activity of waste extracts from the peel, seeds, and pulp of Kintamani tangerines and to implement a practical approach to by-product management based on a zero-waste system. The method used is a pure experimental study with a post-test only design. Extraction was carried out through repeated maceration using methanol as a solvent. Antioxidant activity was tested using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method and analyzed with a UV-Vis spectrophotometer at a wavelength of 517 nm. The results showed that the peel extract of Kintamani tangerines could fade the purple color of the DPPH solution, whereas the seed and pulp extracts did not show a significant change. The IC50 values were 136.17 ppm for the peel extract, 6727.86 ppm for the seed extract, and 497.57 ppm for the pulp extract. In conclusion, the peel extract of Kintamani  tangerines exhibited the highest antioxidant activity among the three extracts, categorized as moderate based on Blois' classification.   Keywords: Antioxidant Activity, Pulp, Kintamani Tangerine, Seed, DPPH, Peel
