Judul: Model Development in Performance Assesment of Stearic cid Industry from Palm Oil
Abstrak: Oleochemical supply to China, especially from Indonesia and Malaysia is very big, about 500 000 ton a year, 90% of the supply is stearic acid (Cham & Purwoko). The other stearic acid importir country are Europe Union and United States of America. This sector is a big opportunity for agroindustry company, especially export oriented industry. The hard competition in this sector pushes every industry do some continuous improvement, so that the output of product has competitive quality. Continuous improvement can be realized when the companies evaluate their performances. The evaluation process needs enormous resource which is the main problem for industry in Indonesia, esspecially oleochemical industry. The performance assesment system is developed by designing an assesment model, using system approach. The object of observation in this performance assesment, i.e. man, market, money, machine, material, method, market, management & environment. The assesment interval is based on expert justification, technical standard and literature study. The model will give assesment from each criterias and conclude the assesment through simple weighting from some criterias quantitatively and qualitatively. The result of research is performance assesment model of stearic acid industry which implemented into application program called SPIAS 1.0. The program has verified base on company annual report and the result has shown that PT. X has ‘average’ performance. Hopefully this program can help company to do self rapid assesment more efficient, so the company could do some continuous improvement.

Judul: Rancang Bangun Penilaian Risiko Mutu dalam Rantai Pasokan Minyak Sawit Kasar dengan Pendekatan Sistem Dinamis : Studi Kasus PT. Perkebunan Nusantara IV (Persero) Unit Adolina
Abstrak: Indonesian palm oil industry has grown significantly in recent years and since 2006 has surpassed Malaysia to become the world’s largest Crude Palm Oil (CPO) producer. With the ever increasing of potential market and market demands for its palm oil products, Indonesia will need to ensure the highest level of palm oil products quality. The main objectives of this research are first, to identify the factors to measure the success of Palm Oil Mills (POM) Adolina’s management. Secondly to design a system dynamic model as a tool to determine the quality risk assessment pattern of POM Adolina. The results from simulation of this model will be referenced when formulating managerial policies. The dynamic model comprises three sub-models, namely production sub-model, transportation sub-model and inventory sub-model respectively. In conclusion, this research produced the formulation of the most important factors to measure management success, namely the level of CPO production and the level of free fatty acid (FFA), and also generated simulation of managerial policies. To obtain them three scenarios were considered, the basic, the dynamic behavior and the risk assessment scenarios. Probabilistic and uncertainty parameters were considered in the third scenario.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
