POTENSI LIMBAH KULIT RAMBUTAN (Nephelium lappaceum) SEBAGAI MINUMAN SEDUHAN HERBAL

Rambutan production in Indonesia in 2017 is 523,699 tons. Consuming rambutan fruit will affect rambutan peel as a waste. Although rambutan peel has the potential to be made into herbal brew drinks products. The research aims were to determine the productivity of rambutan peel as a raw material for herbal beverage and estimate the benefits to be obtained. The study used local rambutan fruit raw material. The research was carried out in the Forest Product Laboratory of Dipterocarps Research Center. The research aimed to determine the processing technology of rambutan peel as raw material for herbal beverage and estimated benefits to be gained. The research was conducted in three stages of activity, i.e. calculation of the potential of rambutan peel as raw material for herbal beverage, making of rambutan herbal beverage and estimated its profit. Rambutan peel can be processed into herbal brew drinks using simple technology, by making the rambutan peel into a dry powder and put it into a brewed beverage bag.

Pengaruh Ukuran Butir Pasir Besi dan Volume Air Laut pada Absorber Type Fins Solar Destilation terhadap Produktifitas Air Tawar

The needs of clean water is especially increased for the living in coastal. Because of that, a simple equipment and low cost operation is needed. Distillation is a method to convert sea water to fresh water by using solar energy. Various research on absorbent plate solar still has been done to increase productivity and efficiency of distillation. In the study, fins absorbent plate was tested with iron ore grain size variation of 0,125 cm, 0,250 cm and flat absorbent plate with iron ore grain size variation of 0,125 cm. The volume of salt water in the basin is also varied of 1, 2, and 4 liters. The results shown that the fin absorbent plate with iron ore size of 0.125 cm and the volume of 1 liter have the highest freshwater productivity and efficiency of 3,7 l/m day and 53,55%, respectively. The daily sun radiation of 16,071 MJ/m .day. The quality of resulted fresh water has fulfilled the standard for drinking water, hence it is consumable
