Abstract

Virgin Coconut Oil or VCO will experience a decrease in quality due to oxidation, which cause rancidity. Adding antioxidants to VCO can help slow down the rancidity of the oil. This study aimed to determine the effect of adding marigold flowers on VCO in terms of free fatty acids (FFA) and water content as well as the functional groups contained in VCO. The VCO preparation technique was carried out without heating followed by the addition of marigold flowers with a ratio of VCO and marigold flowers of 100:1; 100:2.5; 100:5 w/w. The VCO without the addition of marigold flowers used as a control. The results indicated that the addition of marigold flowers could improve the quality of the VCO, characterized by a decrease in FFA levels and water content. The functional groups of VCO with the best quality (a ratio of VCO and marigold flowers of 100:1) were analyzed by FTIR (Fourier Transform Infrared Spectroscopy), namely OH, CH¬3, C=O, aliphatic C=C, and aliphatic C?C.

Abstract

This paper investigated the effect of the mass of the waste valve of hydraulic ram pump which has been designed and installed to deliver the clean water to the community house in the Munduk Gunung area, Petang Village. Public facilities are still minimal. One of them is the unavailability of clean water service facilities for the community, where people still rely on rainwater or buy water tanks. In accordance with the name of the area, this residential area is located in the highlands (512 m.swl), while the available water sources are in the lowlands (410 m.swl) with an elevation difference of 102 meters. The distance from the spring to the reservoir is 600 meters through a steep cliff. Initial survey results show that the spring has a flow capacity of about 3 liters/second and a potential head of 4.5 meters. The hydraulic ram pump has been designed, built, installed and operated with funding supported through the PNBP service grant from Udayana University, the PUMA scheme. The hydraulic ram pump performance test has been carried out on five variations of the waste valve mass. Performance testing shows that this hydraulic ram pump reaches its optimal performance at a mass of 3.25 kg of waste valve. Under these optimal conditions, this hydraulic ram pump operates at a total efficiency of 95% with a pumping flow of 0.115 lt/sec or 9.94 m3/day) at a pumping elevation of 102 meters, with an economic value of up to Rp. 17,885,000 per month. Therefore, it is with an investment cost of around Rp. 42,500,000 and requires almost no operational costs because it does not require fuel or electrical energy, consequently this hydram pump is very profitable to apply. Keywords: Hydraulic ram pump, waste valve mass, pump performance, Munduk Gunung area, Petang village.
