Judul: Aplikasi SIG dalam Penentuan Lokasi Hutan Kota Sebagai Mitigasi Bencana Angin Puting Beliung di Kabupaten Bondowoso
Abstrak: Cyclones disaster in Bondowoso regency is an annual natural disaster caused a lot of losses. Within the last 5 years (2009-2013), 95 incidences of cyclone have hit 75 villages in Bondowoso regency. Development of urban forest is expected to be the best solution to overcome or prevent the occurrence of cyclones disaster. Characteristics of the villages with most frequent cyclones disaster is a low area at an altitude below 500 meters above sea level, is a flat area with 0-8 % slope as big as 1045.07 ha or 89.21 %, had a temperature surface between 30˚ - 35˚C as big as 909.45 ha or 77.63 %, and is a place dominated by the type of land cover in the form of a fairly open area as big as 853.45 ha of rice fields or by 72.85 %. Area with the highest weight value that needs to be built urban forest that serves as a disaster mitigation cyclones scattered in 201 villages with an area of 32420.35 ha or 20.83 % of the total area of Bondowoso regency obtained from the scoring and overlay the four characteristics.

Judul: Geographic Information System Application on Urban Forest Development in Bandung City
Abstrak: Bandung sebagai ibukota Jawa Barat merupakan salah satu kota metropolitan yang menghadapi masalah kepadatan penduduk. Hal ini menyebabkan meningkatnya jumlah konversi lahan dan penurunan ruang terbuka hijau di Bandung. Penelitian ini mengkaji kebijakan hutan kota, distribusi spasial hutan kota, serta metode merancang penentuan lokasi prioritas hutan kota dalam pengembangan hutan kota di Kota Bandung menggunakan GIS. Kebijakan kehutanan di Kota Bandung hutan kota terkait terdiri dari Kota Bandung Peraturan No.25 / 2009 dan Rencana Tata Ruang Kota Bandung. Berdasarkan analisis dari Landsat 8, luas hutan kota secara factual di wilayah Bandung dari 338,94 hektar (area kurang dari 10% dari Bandung), sehingga perlu diketahui lokasi yang sesuai untuk dikembangkan menjadi hutan kota. Metode ini merupakan overlay dari beberapa parameter: ketinggian, kemiringan, tutupan lahan, iklim, kepadatan penduduk, dan jarak dari protokol. Faktor-faktor yang menjadi parameter dalam menentukan prioritas lokasi hutan kota dianalisis menggunakan AHP (Analytical Hierarchy Process). Kecamatan yang perlu dikembangkan menjadi hutan kota (prioritas 1) di Bandung yaitu Mandalajati, Cibiru, dan Ujung Berung., Bandung as the capital city of West Java has been facing with massive land conversion leading to reduced of green open space, which in fact affect to the quality of environment. This study will examine current urban forest policy- Bandung City Regulation No. 25/2009 and Spatial Plan of Bandung City, spatial distribution of urban forest, and also to develop method to prioritize location for urban forest design in Bandung using GIS. Method used in this study was overlay of several parameters; altitude, slope, land cover, climate, population density, and the distance of the protocol road. Parameters measured were analyzed using AHP. Based on Landsat 8 analysis, the factual urban forest areas only cover 338.94 hectares (less than 10% area of Bandung), and thus it is necessary to locate the appropriate location for a well-designed urban forest development. Result shows that there was three scores indicating the rank prioritization as the 652,65 hectares for the first rank, 7336,65 hectares for the second rank and lastly 8733,61 hectares. It is concluded that the first priority to be developed for urban forest in Bandung was Mandalajati, Cibiru, and Ujung Berung that fall within the first rank.

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.
