Judul: Agroindustrial risk management of palm oil-based biodiesel
Abstrak: Biodiesel is fuel generates from vegetable oils that have properties similar to diesel oil. The advantages of biodiesel compared to diesel is an environmentally friendly fuel because it produces much lower emissions (sulfur free, low smoke number) in accordance with global issues, higher cetane number (> 57) so that the combustion efficiency is better than diesel, lubrication properties of the piston engine; biodegradable, a renewable energy because it is made from natural materials, and improve the independence of fuel supply because it can be produced locally. The purpose of this research is to design the risk management decision support system for agro-industry development of oil palm-based biodiesel. The design methods used include: a) risk analysis of raw materials, processing, and marketing using a non-numeric ME-MCDM. Measurement and assessment of financial risks using risk criteria (coefficient of variation). Financial feasibility studies using the instruments: net profit, NPV, IRR, payback period, the BEP and the Net B / C ratio. Determination of objectives and risk management strategies using the rule-base. AHP is used to obtain an alternative value in the aspect of raw material procurement, processing, and marketing. ISM digunakam in institutional management. This research resulted in a decision support system that is useful to help decision makers in addressing the risk of agro-bio-diesel. Risk management model is designed in a decision support system (DSS) with the name "Biodiesel- RM", can be used by industrial users and investors in the field of biodiesel. SPK software development using Microsoft Visual Basic Version 6.0 yamg consists of three main components namely database management system, knowledge base management system and model base management system. Model base management system consists of 4 sub-model: risk analysis of raw materials, processing of risk analysis, risk analysis marketing, and financial risk analysis. Risks can be reduced through agro biodiesel biodiesel industry cluster approach, with fasilisator FKMKI Biodiesel (Forum biodiesel industry cluster management communication), which was formed and initiated by the community clusters and the formation of cooperative agro-industrial biodiesel supported by investors, financing institutions, universities and research institutions

Judul: A Web-Based Decision Support System For Quality Of Biodiesel
Abstrak: The main objectives of this research is to create a model of decision support systems for small industrial biodiesel that can be easier for processors biodiesel to manufacture biodiesel in accordance with the standards. A web based decision support systems for quality of biodiesel has four models, namely the determination of the model that produces the best decision for biodiesel processing in accordance with the characteristics of raw materials, the calculation model needs an additional ingredient in the treatment process that produces the decision to the needs of the process, determine the model that produces biodiesel product quality decisions in accordance with quality standards, and model analysis on the incompatibility of biodiesel quality that generates suggestions for the user. Decision support systems programme using the method of decision tree and rules based. The main conclusions of this research is produces a web based decision support systems for quality of biodiesel output of the simulation system that aims to facilitate the processing of biodiesel, especially small industries in producing biodiesel and biodiesel can be produced in accordance with standard (SNI).

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
