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

Judul: Pemanfaatan Tumbuhan Obat Pada Masyarakat Kampung Sekitar Kawasan KHDTK Haurbentes Jasinga Bogor
Abstrak: Area KHDTK ( Kawasan Hutan Dengan Tujuan Khusus ) Haurbentes is the forest that function as forest research. In land research forestry there are various kinds of herbs often used by community as a drug to cure diseases. With respect to such matters, then this research was conducted. The aim of this research is to identify plant species drug used of the surrounding community research KHDTK Haurbentes forest area. This research carried out in 2 town about are in Haurbentes town and Cikeusal Wirajaya village. Research is done in February to March 2014. Based on research, characteristic of community dominated by the use of medicinal herbs age 50-60 years, education has elementary education, and society most much use of medicinal herbs freelance. Plant species identified as much as 21 species of the family 16 that can be used by local community as an alternative medicine. This type of the disease ever suffered by the people around KHDTK Haurbentes there are 15 groups of diseases/use of medicinal plants which are exploited by the community.

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.
