Judul: Kontribusi pengelolaan agroforestri terhadap pendapatan rumah tangga petani (Studi Kasus: Desa Bangunjaya, Kecamatan Cigudeg, Kabupaten Bogor, Provinsi Jawa Barat)
Abstrak: Hutan rakyat merupakan hutan yang dibangun, dikelola, dan dimanfaatkan oleh rakyat di atas tanah milik. Pada kenyataannya di lapangan, hutan rakyat tidak berwujud secara murni tetapi berwujud kebun campuran pepohonan dengan tanaman pertanian, buah-buahan dan pangan lainnya, yang dikenal atau disebut sebagai agroforestri. Agroforestri adalah sistem penggunaan lahan yang mengkombinasikan tanaman berkayu dengan tanaman tidak berkayu (kadang-kadang dengan hewan) yang tumbuh bersamaan atau bergiliran pada suatu lahan, untuk memperoleh berbagai produk dan jasa (services) sehingga terbentuk interaksi ekologis dan ekonomis antar komponen tanaman. Sistem pengelolaan agroforestri sendiri dibagi menjadi dua jenis yaitu sistem agroforestri sederhana dan sistem agroforestri kompleks. Kedua sistem agroforestri tersebut sama-sama menghasilkan beberapa komoditi seperti kayu, buah-buahan, dan tanaman pangan. Berdiri di atas wilayah seluas 11,62 km² dan dihuni 8.246 jiwa dengan kepadatan penduduk rata-rata 710 jiwa/km² (BPS, 2009), Desa Bangunjaya, Kecamatan Cigudeg, Kabupaten Bogor, Provinsi Jawa Barat menjadi salah satu desa yang menjadikan agroforestri sebagai sumber ekonominya. Berbeda dengan agroforestri yang pada umumnya menghasilkan kayu atau padi dan palawija sebagai komoditas utama, buah-buahan justru menjadi primadona di Desa Bangunjaya.

Judul: Kontribusi Pengelolaan Agroforestri Terhadap Pendapatan Rumah Tangga Petani (Studi Kasus Di Desa Sukaluyu, Kecamatan Nanggung, Kabupaten Bogor, Jawa Barat)
Abstrak: Agroforestry is a land use system which combines woody plants with agricultural crops. Various previous researches concluded that agroforestry can improve the household income of farmers. Sukaluyu Village became one of the villages that make agroforestry as a source of their economy. The research was conducted to provide information regarding the contribution of agroforestry management to the farmer households as well as information about the agroforestry system adopted by local farmers. The results of research showed that farmers implement agroforestry system who combined trees with crops and trees with medicinal plants in which land management with agroforestry systems contribute to farmer household income was 68.60%.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
