Abstract

Biodiesel is a promising alternative fuel that can be produced From vegetable oils, animal fats or recycled frying oil by esterification or transesterification with alcohol. Rice bran is one of an alternative feedstock to produce biodiesel. The aims of this research are to produce crude biodiesel by in situ esterification without incubation and incubation of rice bran at lipase optimum temperature and pH using sulfuric acid as catalyst, and to characterize rice bran biodiesel by analyzing concentration of fatty acid methyl ester (FAME), triglyceride, diglyceride and monoglyceride, biodiesel yield, density, viscosity, cetane index, cloud point and flash point. The research used in situ esterification. The extraction and biodiesel production occurred simultaneously. Rice bran was incubated at optimum temperature and pH before in situ esterification for one, two and three weeks incubation. Rice bran lipase had the highest activity of 7.89 pmol/ml minute at 33C and pH 6. 50 gram rice bran was transferred to three round bottom flask and 200 ml methanol was added.

Abstract

Seiring dengan proses perubahan paradigma pembangunan dari model top down menuju model bottom up, peranan masyarakat lokal menjadi semakin penting dalam berbagai tahapan proses pembangunan. Pemahaman yang mendalam tentang sumberdaya lokal utamanya komunitas lokal yang antara lain mencakup pola hubungan dan jaringan kerja sama yang lebih dikenal secara luas sebagai modal sosial (social capital) merupakan suatu kebutuhan yang mendasar dalam proses perencanaan dan pelaksanaan pembangunan.Pemanfaatan sumberdaya sosial secara optimal akan mendukung peningkatan efektivitas program pembagunan pedesaan. Hal ini tidak hanya memacu pertumbuhan ekonomi, namun juga sebagai penyangga dan pemelihara solidaritas sosial dan daya ikat masyarakat lokal. Pada akhirnya akan mendukung model pembangunan yang berkelanjutan bagi masyarakat pedesaan dan lingkungannya.Pemahaman yang komprehensif tentang sumberdaya social capital memungkinkan perencana pembangunan untuk mengidentifikasi secara tepat akan potensi sisi positif dan negatif. Hal ini sangat penting ketika merumuskan strategi penguatan sisi positif dan menekan sisi negatif potensi social capital dalam pembangunan masyarakat pedesaan.Dukungan dan penguatan terhadap pola jaringan dan kerjasama masyarakat yang semakin terbuka (inclusive) seperti tercermin dalam pergeseran dari dimensi bonding menuju bridging dan linking memungkinkan masyakat lokal untuk memperluas dan memperkuat berbagai aspek kerjasama.

Abstract

The quality of human resource is the main key to the success of agriculture development. Experience has proven that in Indonesia agriculture extension as a part of agricultural human resources development significantly contributes to the success of many agricultural development programs. Hence, agricultural extension holds a strategic position in agricultural development. On the other hand, challenges of globalization urges extension worker to improve their skills to pace up with the changes occurring on the farmers side, who are becoming more advanced in many aspects, including perspective, knowledge, skill, as well as being more analytical. With these logics, the formulation of a vocational competency standard for agricultural extension workers is called for to strengthen their competitiveness and to develop accountability to those who benefit from agricultural extension services. The development of a competency and accreditation standardization system for government agricultural extension workers is implemented by placing extension worker either as functional staff or as professionals, while for independent and private extension agents, agricultural extension activities are merely vocational. Thus government extension workers, besides as functional staff, should also be in compliance with the accredited competence standards, proven by the possession of a vocational certificate. The competency of agricultural extension workers can be advanced towards their competency as agents of knowledge transfer to the farmer community, consisting andragogy competency, personality competency, social competency, and professional competency.
