Abstract

This study was carried out on two phases of Crude Palm Oil (CPO) to determine the total and composition ofcarotenoid and vitamin A content. Total of carotenoid was analyzed using spectrophotometer UV-Vis, and then theresult was calculated by Gross (1991) equation. The vitamin A content was calculated by NAS-NRC equation (1974).The type and composition of both phases of CPO were determined by Choo’s method (1994) by using HPLC withPhoto Diode Array (PDA) detector. The sample was prepared in two methods, with and without saponification. Theresult shows that total carotenoids in liquid and solid phase of CPO are 536 ± 13.2 g/g (liquid), 352 ± 17.7 μg/g(solid) and the vitamin A were 89.4 ± 2.2 RE (liquid), 58.7 ± 3.0 RE (solid), respectively. The carotenoid compositionsof both phases of CPO were dominated by - and -carotenes. The result shows that - and -carotenes preparedby saponification method in liquid phase are 29.03% and 60.88%, and without saponification (direct method) are28.14% and 59.44%. The result for solid phase shows that - and -carotenes by saponification are 25.89% and60.81%, and without saponification (direct method) are 30.00% and 56.92%. The research also shows the advantagesof using HPLC with PDA detector for identification and analysis of type and carotenoid composition.

Abstract

This community service program aims to increase environmental awareness in the Cidadap Village community through the creation of biopores. This activity is part of the KKNM program, which includes education, health, and sustainable environmental management. Through outreach and education by students, the community is educated about the importance of biopores in maintaining soil quality and preventing flooding. This activity is also related to the stunting prevention program and addresses other social issues such as bullying in local schools. The participatory method used directly involves the community, increasing their involvement and awareness of environmental issues. The results show an increase in community knowledge about environmental management and the positive impact of biopores on soil health. It is hoped that this activity can become a model for other villages to increase environmental awareness and sustainable natural resource management.
