Judul: Efektivitas kolaborasi antara perum perhutani dengan masyarakat dalam pengelolaan hutan kasus PHBM di KPH Madiun dan KPH Nganjuk, Perum Perhutani Unit II Jawa Timur
Abstrak: Menurut Kiwari (1983) dalam Suharjito dan Dudung (1998), social forestry adalah ilmu pengetahuan dan seni menumbuhkan pohon-pohon dan atau vegetasi lain pada lahan yang tersedia, di dalam dan di luar areal hutan tradisional dengan melibatkan masyarakat untuk tujuan menghasilkan tata guna lahan yang seimbang dan saling melengkapi (Tiwari, 1983). Secara umum, penelitian ini bertujuan untuk melihat dan menjelaskan proses kolaborasi yang terbangun selama ini antara Perum Perhutani dengan masyarakat khususnya petani hutan dalam pengelolaan hutan.

Judul: Peran Pengelolaan Hutan Bersama Masyarakat dalam Mengatasi Masalah Pencurian Kayu Studi Kasus di KPH Jember Perum Perhutani Unit II Jawa Timur
Abstrak: Forest could simply be defined as a unified ecosystem in which the biological resources are dominated by trees that are tightly bound each other, in terms of environmental balances. Due to the various potential applications of any forestry resources, make forest prone to any missed-law exploitations (e.g., illegal logging). As a consequence, to negate the number of illegal logging, Perum Perhutani has initiated a program_Forest Management based of Community (PHBM). Hence, this study was aimed to evaluate the effectiveness of PHBM as an effort to cut-down illegal logging especially in the boundary of KPH Jember Perum Perhutani Unit II East Java. This research was conducted by employing such stratification-of-random-sampling method, with group classifications of monthly income and occupation. Additionally, selection of the villages was according to the purposive–sampling method. There were two distinguishable data utilized such as: (i) primary data (field studies and interview of 90 respondents) and (ii) secondary data (information found in books, scientific journals, thesis, dissertation and other documentary resources). The data showed several concluding remarks of illegal logging characteristics, such as (a) types of wood being stolen, likely sengon, teak and mahogany, (b) diameter of the tree of approximately 10-30 cm, (c) reason for selecting such diameter as it is easy to transport, and (d) the illegal logging becomes a major alternative way for the local people to fit out them necessaries. Furthermore, the number of the illegal logging in 2008-2012 decreased from 229 to 118 cases, except for the RPH Mumbulsari which was still increased. The main role of local people for tackling illegal logging located in RPH Mumbulsari, RPH Garahan and RPH Jelbuk was done by patrol activities including making such control-posts in certain locations. However, the data showed the effectiveness of PHBM program on the RPH Mumbulsari wherein a pattern of mixed-planting between teak and crops (palawija) implemented could not reduce the number of illegal logging significantly, whereas one that a pattern of mixed planting between pine and crops or coffee (RPH Garahan and RPH Jelbuk) carried out showed the positive impacts by the reduced number of illegal logging.

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.
