Abstract

In this paper, we consider fuzzy inventory of crude palm oil. First, we determined the demand and imperfect product quality as triangular fuzzy numbers to obtain the fuzzy inventory total cost. Secondly, using the signed distance method to defuzzify, we get the estimate of the total cost in the fuzzy sense. Moreover, we also developed the economic production quantity (EPQ) as the initial formulation. The result of study can be stated as follows: if the level of demand risk is increased then the order will also be increased, while if the level of quality risk is increased then the order will be decreased. Additionally, the quality risk factor model is successfully applied in the inventory control of crude palm in harbor storage. Abstract in Bahasa Indonesia: Makalah ini menjelaskan sebuah model persediaan minyak sawit kasar menggunakan logika fuzzy. Langkah awal yang dilakukan adalah menetapkan bentuk fuzzy pada permintaan dan produk dengan mutu kurang baik sebagai bilangan fuzzy segitiga ke dalam total biaya persediaan. Teknik defuzzifikasi yang digunakan adalah signed distance sehingga total biaya persediaan dapat diperoleh. Studi ini mengembangkan economic production quantity (EPQ) sebagai formulasi dasar. Hasil studi adalah peningkatan kadar risiko permintaan akan meningkatkan ukuran pemesanan sedangkan peningkatan kadar risiko mutu akan menurunkan ukuran pemesanan. Penambahan faktor risiko mutu pada model EPQ telah berhasil diterapkan dalam pengendalian persediaan minyak sawit kasar di tangki timbun pelabuhan. Kata kunci: persediaan, minyak sawit kasar, fuzzy, risiko mutu, signed distance.

Abstract

As the country's largest palm oil producer in the world, Indonesian palm oil production is still encounter political barriers or non-tariff economy of several countries. Sustainable development policies have a role to overcome these obstacles. The research problem is how to build policies through the performance based risk assessment for sustainable palm oil supply chain in Indonesia. The research objective is to recommend policies that supported by performance-based risk assessment models for sustainable palm oil supply chain in Indonesia. Performance-based risk assessment algorithms have been developed and verified in a comprehensive manner. Model verification is conducted by analyzing the performance of crude palm oil supply chain based on expert’s analysis. This study has obtained the necessary indicators to assess the risk based on performance of sustainable crude palm oil supply chain. Model application has shown that risk level of sustainable crude palm oil in Indonesia relating to economics, environmental, and social aspects are moderate, respectively. However, there are some indicators that need to be considered with the level of risk is quite high, namely demand rate, quality of palm oil, timelines of product delivery, availability of crude palm oil and bullwhip effect. This paper has recommended some policies to address those risks.
