Abstract

A model of production planning in Crude Palm Oil industry is discussed on this paper. An interactive model is made due to the involvement of decision maker’s preference in production planning. The model is built for Nucleus-Plasma palm estate system. The sources of fresh palm fruit bunches are obtained from nucleus estate, plasma estate and outsourcing. A single objective fuzzy linear programming model is built with the following steps: (1) Decision variables, parameters are identified from the real system of Crude Palm Oil industry as well as determination of constraints and objective function; (2) Fuzzy parameters are determined using modified S curve membership function. Linear programming model is also formulated at this step. Risk quality of raw material is represented by percentage of defect raw material; (3) Model is then validated using data from Nucleus-Plasma palm estate system. The result shows that S curve membership function is able to represent the preference of decision makers.

Abstract

This paper discusses the knowledge creation process in one department, in a higher educational context, and the possible actions to take to improve the efficiency and effectiveness of the knowledge creation system in it. We conducted a case study at one department of a university that strives to improve its innovations, in terms of their quantity and quality.We used a soft system methodology to investigate the knowledge creation system in the chosen department. From the study, we conclude that the department can be considered as a learning organization, within which its staff continually create, acquire and transfer knowledge. This department has a learning environment which is conducive, concrete learning processes, and leadership that reinforces learning. In the context of producing agroindustry innovations, the knowledge creation system in this department is considered to be less effective since it frequently happens more at individual or small group levels. To improve its effectiveness, the management may facilitate the institutionalization of knowledge creation processes at every phase of the interactions between tacit and explicit knowledge.

Abstract

Besides more complexes, the agricultural product supply chain also was probabilistic, dynamic and higher dependencies. This happened because of the agricultural product was easy broken, the process of planting, the growth and the harvesting depended the season, the yield had variety form and measurement, and the agricultural product was bulky so that the agricultural product was difficult to be handled. The height of the dependency level and the complexity from the supply chain network of the agricultural product made this chain to be more susceptible to the disturbance. The risk of failure for the supply chain could be happen internally (the relations between the organization and the network of the supplier) and externally (between the network of the supplier and its environment). Therefore, the needs for supply chain risk management to avoid a result that can continuously occur at any point in the supply network. The purpose of this study was to describe a model of evaluation and risk management supply chain of agricultural products. Model could identify risks of every level of supply chain and provide solutions that can be done to minimize them. The index value of risk on farm level was 26 % higher than the risk at the level of collector (8.78 %) and distributors (8.31 %). The model can optimize farmers’ planting schedules to reduce supply risk and price, while also optimizing the selection of suppliers at the level of collectors and distributors with the consideration of minimizing risk and optimizing profits. ABSTRAKSelain lebih kompleks, rantai pasok produk pertanian juga bersifat probabilistik, dinamis dan kebergantungan yang tinggi. Hal ini terjadi karena produk pertanian bersifat mudah rusak, proses penanaman, pertumbuhan dan pemanenan tergantung musim, hasil panen memiliki bentuk dan ukuran yang bervariasi, dan produk pertanian bersifat kamba sehingga produk pertanian sulit untuk ditangani. Tingginya tingkat kebergantungan dan kompleksitas dari jaringan rantai pasok produk pertanian menjadikan rantai pasok lebih rentan terhadap gangguan. Risiko ganguan rantai pasok dapat terjadi secara internal (relasi antara organisasi dengan jaringan pemasok) dan eksternal (antara jaringan pemasok dengan lingkungannya). Oleh karena itu perlu pengendalian risiko rantai pasok agar dapat menghindarkan akibat berkelanjutan yang dapat terjadi pada setiap titik dalam jaringan pasokan. Tujuan dari kajian ini adalah menjelaskan suatu model evaluasi dan manajemen risiko rantai pasok produk pertanian. Hasil validasi model dapat mengidentifikasi risiko setiap tingkatan rantai pasok dan memberikan usulan tindakan yang dapat dilakukan untuk meminimalkan risikonya. Nilai indeks risiko pada tingkat petani sebesar 26 % yang lebih tinggi daripada risiko pada tingkat pengumpul (8,78 %) dan distributor (8,31 %). Model dapat mengoptimalkan jadwal tanam petani untuk mengurangi risiko pasokan dan harga, selain itu juga telah dimodelkan optimasi pemilihan pemasok pada tingkat pengumpul dan distributor dengan pertimbangan minimalisasi risiko dan optimalisasi keuntungan.
