Abstract

West Sumatra has great potential in developing biomass based on palm oil waste. This is because the largest plantation production in West Sumatra comes from the oil palm commodity of 1,082,820 tons in 2014. Therefore, it is necessary to design a model of supply chain biomass network for the distribution of Empty Fruit Bunches (EFB) from CPO factory suppliers located in West Sumatra and distributed to Depot Pertamina Teluk Kabung. Stages performed in the implementation of this study began with a preliminary study to determine the potential of biomass in West Sumatra. Furthermore, the design of chain supply chain optimization model by identifying supply chain activity, knowing the characteristics of supply chain system and make the formulation of mathematical model. The design of supply chain biomass from Empty Fruit Bunches (EFB) in West Sumatera, starting from raw material Tandan Kosong Kelapa Sawit (TKKS) sourced from Crude Palm Oil (CPO) factory in West Pasaman Regency and surrounding. This is because Pasaman Barat Regency is the central agroindustry of oil palm plantation which has 17 most palm oil factories in West Sumatra. The potential of bioethanol derived from CPO waste can be done by establishing bioethanol plant located with the same CPO factory so that it is adjacent to the source of the raw material. The result of the mathematical model mixed integer linear programming is placement of bioethanol plant location at PT Pasaman Marama Sejahtera with medium scale and total cost of IDR 251,563,700,000.00.

Abstract

Construction project implementation process is often found inefficiency and problems at every stage of the construction process. Inefficiencies are caused because construction projects have high levels of fragmentation. The high level of fragmentation cannot be separated from the complexity and many work items on construction projects. To reduce the problem of inefficiencies in the implementation of construction projects required good supply chain management or better known as supply chain management (SCM) on construction projects. Therefore it is necessary to study the management of SCM in the construction project to reduce the inefficiency that occurred. SCM management of construction projects is done by designing SCM performance measurement systems in construction projects. This performance measurement system produces indicators that are combined with the Supply Chain Operation Reference (SCOR) method. So it helps in performing SCM performance measurement on construction projects. From the design results, obtained 14 SCM performance indicators on construction projects. The performance indicators are then used to perform SCM performance measurement of cement plant construction projects. From the measurement results obtained SCM performance value of 41 from a scale of 100. This shows the performance of SCM on construction projects for the construction of the cement plant is at a marginal level.
