Judul: Pemanfaatan Tumbuhan oleh Masyarakat di Sekitar Hutan Pendidikan Gunung Walat Sukabumi
Abstrak: Society, which lives in forest margin area such as one in Hegarmnah Village, Cicantayan, Sukabumi, has interaction with forest. The changing lifestyle of the society threaten the existence of their traditional knowledge. This research needed to identified the diversity of plants used by forest margin society of GWUF. Data of used plant diversity were collected through semi-structured interview. Plant species was classified into 8 group of purpose, that is for medicinal purpose, food, aesthetics, fire-wood, building materials, cattle feeding, aromatic, and other purpose. Medicinal purpose plant is the most group used plants, amount of 145 species of 54 family. Herb habitus is the most used plants by a value of 36,56%. Plant’s part that mostly used by the people was the leaves with the amount of 51,61% since leaves were easy to obtain and process

Abstrak: Pemanfaatan tumbuhan di sekitar hutan merupakan tradisi masyarakat yang tinggal di sekitar hutan. Penelitian ini bertujuan mengidentifikasi spesies tumbuhan berguna dan mengetahui bentuk pemanfaatan tumbuhan serta aksi konservasi masyarakat Kampung Wangun I. Teknik pengumpulan data melalui studi pustaka, observasi lapang, dan wawancara 35 responden dengan metode snowball sampling. Hasil penelitian diketahui tumbuhan berguna teridentifikasi sebanyak 145 spesies dari 63 famili. Famili terbanyak yaitu famili Fabaceae 13 spesies (29.9%). Tumbuhan obat merupakan spesies terbanyak dimanfaatkan warga 85 spesies dari 45 famili. Bentuk kearifan tradisional dalam pemanfaatan tumbuhan yaitu pembuatan gula aren. Aksi konservasi warga dalam melestarikan lingkungan meliputi pemanenan madu hutan, dan budidaya tumbuhan hutan.

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.
