Judul: Sistem Pakar Prediksi Produktivitas Padi Pandan Wangi Menggunakan Logika Fuzzy
Abstrak: The increase of superior commodity production value is Indonesian government's efforts to survive in competitive trade competition. Superior commodity that has become the hallmark of Indonesia is beras pandan wangi. This commodity has a distinctive taste and fragrance, well-known in regional, national and international markets. Expert system can help the effort in order to run effectively and efficiently by predict pandan wangi paddy productivity. This system has three inference systems, the first is to determine the condition of the land with the input level of nitrogen, phosphorus, potassium and acidity level of the soil, the second is to determine the environmental conditions with rainfall input, land elevation and irrigation (water discharge). The second output of the inference will become an input for the third inference system which has pandan wangi paddy productivity as the final output. This expert system using mamdani fuzzy logic model and mean of maximum (MOM) for defuzzification. This expert system has an accuracy of 61.72%, 62.96% and 88.88% for the first, second, third inference system respectively.

Abstrak: The objective of this research was to develop a decision support system for increasing Sustainable productivity on fishery agroindustry supply chain management that provides information and decision alternative to all stakeholders related to catch, effort, added value, agroindustry performance and sustainable fishery in Southeast Maluku District. Stock prediction model measure Value of CMsy and Emsy with equilibrium Schaefer as indicator of surplus production. Added value analysis model use to measure added value with profit margin. Agroindustry performance analysis model use to measure performance of Agroindustry with Balanced Scorecard (BSC) method, terperrate vision and company strategy into four different perspectives, financial, customer, internal Business process, and learning and growth. Sustainable model analysis with MDS method (Multidimensional Scaling). Stock prediction model showed that catch and effort in Southeast Maluku District still below sustainable maximum level. Added value analysis model the result showed that the added value is very low. Analysis agroindustry performance model there sult showed that financial perspective has greatest achievement performance index Sustainability model used to calculate the level of sustainability off isheries in South east Maluku District measured the dimensions of the three- dimensional ecological, social, and economic. MDS results showed that all the dimensions included in the category of less sustainable. The main conclusion of this research is provide information to the agroindustry fishery supply chain actors related catch and effort. added, agroindustry performance, and sustainability fishery in Southeast Maluku District.

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.
