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: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
