Judul: Optimalisasi unit produksi sayuran organik di Yayasan Bina Sarana Bakti, Kecamatan Cisarua, Kabupaten Bogor
Abstrak: Memaksimalkan keuntungan pertanian dapat dilakukan dengan mengatur dan memilih pola tanam yang mementingkan baik teknis dan aspek ekonomi. Tujuan dari penelitian ini adalah untuk menentukan pola tanam optimal sayuran dalam memaksimumkan keuntungan Yayasan Bina Sarana Bakti. Menggunakan model program linier, hasil penelitian menunjukkan bahwa pola tanam optimal untuk Yayasan Bina Sarana Bakti memiliki kombinasi pola tanaman yang berbeda dari kombinasi pota tanaman aktual. Pada kondisi optimal tanpa kendala pasar dan penanaman aktual, maka akan menghasilkan keuntungan 75.28% lebih tinggi daripada pola tanam aktual.

Abstrak: Maximizing profit of agricultural can be done by arranging and choosing planting combination that considered both technical and economic aspect. The aim of this research was to determine the optimum planting pattern of vegetables in maximizing profit at Yayasan Bina Sarana Bakti. Using Linear Programming models, the result showed that optimal planting pattern for Yayasan Bina Sarana Bakti has different cropping pattern than the actual cropping pattern. The optimal condition of cropping pattern creates profit 75.28% higher than actual cropping pattern.

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.
