Abstract

Performance of Coconut Farming with Banana Plant and Cassava in North MinahasaThe research was done from June to July 2010 in Maumbi village, Kalawat Sub District, North Minahasa District. The respondent were chosen by using Purposive Random sampling method. Data were collected as follow : plant cultivation and yield processing, and its price. The objectives of the research was to determine the productivity and farme’r income on multiply crops planting system consisting of coconut and banana, coconut and cassava. Research result showed that the higher the plant production the higher the farmer’s income. Farmers having coconut palm with production of 2 ton/ha, applying monoculture planting system and sold coconut products in forms of copra and charcoal had a net income Rp. 11,26 millon/ha/year, while those who sold coconut products in form of coconut without the husk had a net income to Rp 7,2 millon/ha/year. This income was categorized lower than minimum regional income. Intrercropping coconut with banana and cassava with production 2 ton copra/ha/year would raise farmer income up to Rp. 24 millon/ha/year, a better family income.

Abstract

Use of Commercial Yeasts on Etanol Processing from Palm NeeraThe objective of this research was to find out commercial yeasts which effective for fermentation sugar palm neera become etanol, efficient processing technique and it can be operated by the farmers/the farmer groups. The research was done from March to June 2009, in the Laboratory of Indonesia Coconut and Other Palmae Research Intitute. The research was conducted in factorial experiment 5 x 4 x 2, using completed randomized design. Factor A is commercial yeast, which consists of A1 = Fermipan, A2 = Mauri-pan, A3 = Gold-Pakmaya, A4 = BrewMax, and A5 = Without yeast. (Fermipan, Mauri-pan, Gold-Pakmaya, BrewMax and without yeast. Factor B is fermentation period which consists of B1 = 0 day, B2 = 2 days and B3 = 3 days. Ethanol processing was conducted by using fermentation and distillation process. The result showed that the suitable yeast for fermentation were Gold-Pakmaya and Fermipan yeast. Using a single destillator, laboratory scale, the first and second processes, produced etanol 28-43% and 72-77%, respectively. Processing etanol 30-32% and 72-77% is economically feasible.

Abstract

Destilation-Dehidration of Bioethanol from Sugar Palm Sap and its CharacteristicsThe experiment was conducted in Engineering Repair of Indonesia Coconut and Other Palmae Research Institute, during August to December 2009. The research used observation methods of destilllation and dehydration process of bioethanol. Treatments consisted of condition of raw material of ethanol with varying characteristics. Twenty five samples were analyzed in this study. Destillation and dehydration process of bioethanol was used continuous system. Observation included the characteristics of distillation temperature, characteristics of bioetanol before and after processing, and material balance of bioetahnol. Analysis of data using multiple regression with OLS (Ordinary leas squares) method. The results showed that characteristics of bioethanol with high ethanol content, contain high sugar content and neutral acidity solution. Where as the low ethanol content , contain low sugar levels and high acidity solution. In the distillation-dehydration process of bioethanol with temprature controlled will increase the ethanol content, sugar content and pH of bioethanol. Bioethanol with 95-96 % ethanol content, sugar content of 18.0 to 18.5 % and pH 7.0-7.38. Bioethanol with contont 30.0 to 35.0, destlled and sehydrated could produce beoethnol content of 95.0-96.0 as much as 29.1 %.
