Judul: Spatial Decision Support Design for Bioenergy Supply Chain
Abstrak: Penelitian ini bertujuan merancang model pendukung keputusan spasial pada rantai pasok bioenergi dengan mengidentifikasi model rantai pasok bagi pengembangan lokasi agroindustri bioenergi dengan pengembangan model spasial potensial lahan agroindustri bioenergi, Penentuan jalur terbaik distribusi limbah padi dari sentra pertanian hingga pabrik pengolahan menjadi bioenergi, Penilaian tingkat keberlanjutan rantai pasok serta merancang prototipe pendukung keputusan spasial untuk meningkatkan efektivitas rantai pasok. Penelitian dilakukan di kabupaten Lebak, Provinsi Banten dengan observasi dan wawancara. Hasil penelitian ini adalah suatu model untuk membantu pengambilan keputusan yang efisien dan efektif dalam mengelola rantai pasok bioenergi. Dengan menggunakan sistem informasi geografis (SIG), model sistem pengambilan keputusan spasial ini menggabungkan data spasial, seperti lokasi geografis wilayah agroindustri bioenergi, lokasi pusat pengumpulan, industri pengolahan bioenergi, dan titik distribusi secara berkelanjutan. Dengan memanfaatkan data spasial ini, model dapat memberikan informasi yang lebih akurat dan terkini tentang kondisi geografis, jarak antara lokasi, dan faktor spasial lainnya yang berdampak pada rantai pasok bioenergi.

Judul: Rancang bangun sistem pendukung keputusan pengembangan agroindustri crude palm oil berbasis spasial
Abstrak: Industrial development should consider the location of spatial entities and their interactions. As with other Agro-Industries, the spatial interaction from oil palm plantations to palm oil mills is a complex problem. The complexity is caused by spread of the location of palm plantations and mills, current and potential transportation network, capacity constraint of each oil factory, perishable characteristics of the product, limited of port and port capacity and supply fluctuation from plantations to the factories due to the plant age as well. This research will give solution which has not yet discussed in the earlier publications by providing an alignment of strategic decision with operational decisions using GIS technology and spatial analysis that can represent the system associated with the space effectively. Decision support model was designed to integrate GIS, spatial multicriteria decision model, shortest path algorithm, transportation model, and financial model as well to determine the optimal configuration of spatial entities in CPO industry. IKG2012 model which has built have the capability to accomodate supply fluctuation from plants to factories due to their productivity and the quality requirement related to distribution time from plants to the factories. Loading and unloading capacity, Port’s tank capacity and barge type are considered as constraints in this system. The results of this study will be useful in developing the logistics infrastructure network for this commodity as well.. The selection of development strategy in CPO agroindustry and improvement of transportation infrastructures will improve the performance of National CPO industry significantly.

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.
