Abstrak: Thermal analysis on biomass that will be applied as biocomposite alternative materials is important in biocomposite production. This study is aimed to know the effect of water content (13, 18, and 23 %) to the glass transition (Tg) on vetiver waste, the castor cake meal, and cornhusk. The results showed that increasing water content will decrease the number of Tg. The number of Tg is about 353.7 C – 365.2 °C, the lowest is the castor seed cake, in the middle is vetiver waste, and the highest is cornhusk. Based on this analysis, castor cake meal is recommended to be biocomposite material, because it has low Tg and easy to be biocomposite production..

Judul: Pengomposan Blotong, Bagas dan Abu Ketel dari Industri Gula dengan Perlakuan Aerasi Aktif dan Perbedaan Nilai C/N Awal
Abstrak: Filter Cake, Bagasse and Boiler wastes in the sugarcane industry has not been used optimally. Therefore, it is necessary to studies use of composting. The purposes of study are to optimize the wastes utilization with composting and to know the influence of different active aerationrate and different initial C/N value on composting process and product. The research method using complete randomized design with two treatments, namely active aeration treatment with air drainage and passive aeration (without air drainage). The aeration active composting in the first week, then in the second week until the end of composting by air supply naturally. Composting consists of three composition based on initial C/N value, they are 30, 40 and 50. In term of active aeration rate, composting consists of two aeration rate, they are 0.8 l/kg.minute and 1.2 l/kg.minute. Parameters monitored during composting such as, temperature is done every day, pH and C/N is every week. Upon the completion of composting which is 42 days, compost is characterized to define the quality of compost and compare with SNI 19-7030-2004. The composting with aeration treatment of active and passive aeration does significantly affect the value of C/N and the different initial C/N value composition significantly affect the value of C/N by anova statistic. The compost, in physically, pH value and potassium content does meet the requirements of the compost, but it does not meet the requirements in water content, phosporus content and C/N Value, based on SNI 19-7030-2004.C/N value of the compost is 23.44 and water content is 54.56%

Judul: Peranan Pesantren dalam Pembangunan Pedesaan
Abstrak: Pesantren (pondok atau pondok pesantren) adalah suatu lembaga pendidikan keagamaan Islam yang pada umumnya tumbuh di kalangan masyarakat pedesaan. Pertumbuhannya merupakan hasil refleksi pimpinan pesantren dan masyarakat terhadap kebutuhan masyarakat sekitar. Disamping sebagai lembaga pendidikan keagamaan, diharapkan pesantren dapat berperan sebagai lembaga sosial kemasyarakatan yang dapat membantu pemerintah dalam menyebar luaskan inovasi pembangunan kepada masyarakat, dan menggerakkan masyarakat agar berperan serta dalam pembangunan.
