Judul: Penggunaan Habitat Banteng di Taman Nasional Baluran Berdasarkan Jejak Aktivitas
Abstrak: Habitat banteng di Taman nasional baluran mengalami perubahan akibat adanya invasi akasia dan aktivitas manusia yang mempengaruhi ukuran populasi. Kondisi tersebut menyebabkan dibutuhkannya penelitian tentang penggunaan habitat berdasarkan sebaran jejak aktivitas banteng. Tujuan penelitian ini adalah mengidentifikasi habitat yang digunakan banteng berdasarkan jejak aktivitas di Taman Nasional Baluran, mengidentifikasi komposisi jenis dan struktur vegetasi di tipe habitat yang digunakan oleh banteng di Taman Nasional Baluran, dan mengidentifikasi komponen habitat yang berpengaruh terhadap keberadaan banteng di Taman Nasional Baluran. Habitat yang digunakan oleh banteng berdasarkan pertemuan jejak aktivitas banteng lebih banyak ditemukan di hutan musim dataran tinggi. Komposisi vegetasi hutan musim dataran tinggi tingkat semai didominasi oleh Commelina diffusa INP 153.33%, dan tingkat pancang dan tiang didominasi oleh Azadirachta indica INP 131.43% dan 300%, dan pohon didominasi oleh Acacia leucophloea INP 147.88%. Komponen yang berpengaruh terhadap keberadaan banteng yaitu gangguan aktivitas manusia dan predator.

Judul: Analisis Pla Penggunaan Ruang Banteng (Bos javanicus d'Alton 1823) di Cagar Alam dan Taman Wisata Alam Pangandaran Jawa  Barat
Abstrak: Banteng is the one of animal which is being extinction (endangered) In Java, banteng distribution limited in several conservation area including Pangandaran Nature Reserve and Pangandaran Nature Recreation Park. The population in this site is fluctuate, in 2007 there's only one adult female banteng, Harm condition brought BKSDA Jawa Barat II as the role play key to make a plan for reintroduction the male banteng into the area, in order to increase the population. Because of that, it is need to conduct a research ecological of the banteng, one of them is space utilization pattern which is give about banteng's existence and activities in several types of vegetation. The data is collected including 1) the type of activity, 2) position and time of activity and 3) habitat characteristic. Behacioral obseravtion is done directly, following the movement of banteng , within seven times replilation. Vegetation analysis is done with transec method.

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.
