Judul: Analysis of supply chain management (scm) system at palm plantation and palm oil factory of gunung meliau, PTPN XIII, West Borneo, in order to improve quality and productivity of crude palm oil (cpo) and palm kernel
Abstrak: Nowadays, supply chain management becomes one of popular systems that are used by companies for increasing profits and costumer trusts. The designing Supply chain management’s case study is implemented at palm oil factory of Gunung Meliau, PTPN XIII, West Borneo. This research by approaching through supply chain management system is focused on the process starting from harvesting of fresh fruit bunches up to producing a high quality and productivity of crude palm oil and palm kernel in accordance with the standart by PTPN XIII. This model is expected to be able to improve the company’s competitive advantage. Competitive advantage can be achieved through value advantage and productivity advantage. Value advantage can be reached through a process that produces high quality products, while productivity advantage is reflected in high-volume production with low-cost process for each unit. Supply chain management system is designed based on identification problems which are traced and observed during supplier research. Supply chain management system is built with three important aspects; those are operational aspect, tactical aspect, and strategic aspect. Supply chain management system is created for stimulating some scenarios about controlling and scheduling of harvesting, delivering, and producing; improving and repairing facilities and infrastructures; implementation of total quality management; and implementation of specification sets through periodic audit.

Abstrak: Supply chain management and quality risk in crude palm oil (CPO)agroindustry was indispensable to achieve superiority in value and productivity. Aspects that require a special attention were quality risk, supply of crude palm oil, harvest-transport-processing management and transportation of fresh fruit bunches. A main problem was the productivity improvement by analyzing all those important aspects. The objective of this research was to design a decision support syste m which consists of integration of risk assessment, inventory control, supply chain optimization, and fresh fruit bunches transportation scheduling.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
