Abstract-The increasing need for vegetable oil about 5 million a year accompanied by the human population growth with the average increase 0.9% requires a consistent effort for Indonesia as the top CPO producer in the world. The efforts to increase the palm oil plantation production faces not only the constraint of the low plantation product but also the lack of downstream palm oil industry development. Also, there is not any specific fund for the plantation. Because of that reason, it is necessary to make an improvement effort for the revitalization of the palm oil plantation in North Sumatera-Indonesian through the huge potential benefits of North Sumatera by modelling palm oil plantation revitalization, to facilitate the relevant parties to find the solution of the constraints of palm oil plantation revitalization so that it can support the CPO agroindustry development in North Sumatera. The implementation of palm oil plantation revitalization in North Sumatera is not high, that is only 17.5 % out of the planned one. It indicates that it becomes the constraint of the palm oil plantation revitalization in North Sumatera. The result of the research shows that several dominant factors influencing the success of the regeneration are among others the land availability and the replanting, the increased productivity of plantation and CPO agroindustry, and the plantation financing. Therefore, it is strongly recommended that the relevant parties such as government, plantation companies, banks and-and farming community be able to synergize so that various influencing factors can be optimized and the maximum increase in the revitalization.

Shrimp agro-industry is one of the food processing industries, which converts raw shrimp into high-value shrimp processed products. The production system used in shrimp agroindustry to respond market demand is a hybrid make to stock (MTS) and make to order (MTO). The decision to determine which products will be stored as supply sources and which products are made to fulfill orders is a critical decision that must be made on the MTS-MTO hybrid system. The concept of customer order decoupling point (CODP) is used to identify material flow points that connect a product with different consumers. This study aims to present a conceptual model in the MTS-MTO hibrid system based on customer order decoupling point (CODP) which is adjusted to product characteristics, production characteristics and market characteristics in the shrimp agroindustry. The results of the study are presented in a business process model template that describes the order of decisions for storing products or making products to fulfill orders and conceptual models in the form of diagrams named the CODP conceptual model on shrimp agroindustry.

Agroindustri udang merupakan salah satu industri pengolahan pangan, yang mengubah bahan baku udang mentah menjadi produk olahan udang yang bernilai tinggi. Sistem produksi yang digunakan pada agroindustri udang untuk merespon permintaan pasar adalah hybrid make to stock (MTS) dan make to order (MTO). Keputusan untuk menentukan produk mana yang akan disimpan sebagai sumber pasokan dan produk mana yang dibuat untuk memenuhi pesanan merupakan keputusan kritis yang harus dilakukan pada sistem hybrid MTS-MTO. Konsep customer order decoupling point (CODP) digunakan untuk mengidentifikasi titik aliran material yang menghubungkan suatu produk dengan konsumen yang berbeda. Penelitian ini bertujuan menyajikan model konseptual pada sistem hybrid MTS-MTO berdasarkan customer order decoupling point (CODP) yang disesuaikan dengan karakteristik produk, karakteristik produksi serta karakteristik pasar di agroindustri udang. Hasil dari penelitian disajikan dalam template model proses bisnis yang menggambarkan urutan-urutan keputusan untuk menyimpan produk atau membuat produk untuk memenuhi pesanan dan model konseptual dalam bentuk diagram yang diberi nama model konseptual CODP pada agroindustri udang. Kata kunci. agroindustri udang; customer order decoupling point;make to stock; make to order.
