Judul: Kajian agroforestry tradisional dan kontribusinya terhadap pendapatan rumah tangga di desa-desa sekitar Gunung Walat
Abstrak: Masyarakat pedesaan yang berada disekitar hutan sangat berpengaruh terhadap keberadaan hutan. Kebutuhan hidup masyarakat seperti kayu bakar, kayu bahan bangunan, tanaman obat mereka peroleh dari hutan. Demikian pula halnya yang terjadi pada masyarakat sekitar Hutan Pendidikan Gunung Walat. Untuk memenuhi kebutuhan kayu bakar sebagian masyarakat mengambil dari hutan. Apabila intensitas kegiatan ini semakin tinggi, maka keberadaan hutan akan terancam kelestariaannya. Sebagian masyarakat saat ini sudah dapat memenuhi kebutuhan tersebut melalui sistem agroforestry, berupa lahan pekarangan dan kebun campuran. Dengan adanya sistem agroforestry tersebut dapat diketahui sejauh mana sistem agroforestry memberikan sumbangan terhadap pendapatan masyarakat yang mengusahakannya. Penelitian yang dilakukan di Desa Hegarmanah dan Desa Cantayan Kecamatan Cibadak, Kabupaten Sukabumi ini dimulai Bulan Oktober November 1995. Penelitian ini bertujuan mengidentifikasi bentuk agroforestry tradisional di lokasi penelitian, mempelajari pengelolaan agroforestry tradisional di lokasi penelitian, mengetahui seberapa besar kegiatan agroforestry tradisional memberikan kontribusi terhadap pendapatan rumahtangga, selanjutnya memperbaiki pengaturan jarak tanam dan jenis tanaman agroforestry yang terdapat di lokasi penelitian. Pengumpulan data dilakukan dengan cara observasi, kuesioner dan wawancara. Data yang diperoleh dianalisis dengan analisis deskriptif.

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.
