Abstract

The increase of production and quality of palm oil and palm kernel oil is strongly influenced by the production of fresh fruit bunches. Therefore, efforts are needed to increase the production of fresh fruit bunches. Pabatu estate is one of business unit of PT Perkebunan Nusantara IV that has head office in Medan, North Sumatera and engaged in the business of oil palm plantation and processing. The Study was aimed to analyze factors that influence the cost application in achieving production target, such as maintenance, premi harvest, security, and transportation. The factors were analized by Analythical Hierarchy Process (AHP) method. The results showed that maintenance cost was in first priority with the quality value of 0,4255. Security cost wast in the second priority with quality value of 0,2739. Harvest premi cost was in the third priority with quality value of 0,1613, and transportation cost was in the fourth priority with quality value of 0,1391, so that PT Perkebunan Nusantara IV Unit Pabatu should pay attention to maintenance cost in achieving production target Keywords: Analythical Hierarchy Process, Crude palm oil, Palm kernel oil, Fresh fruit bunch, Production system.

Abstract

The role of food commoditis (particularly rice) since years ago in Indonesia, was so good, as rice is a basic foodstuffs for the majority of Indonesian. Food needs of rice in our country is never recedes, but increased from year to year, in accordance with population growth. The importance of this report was to forecast rice plant production by means of rice plant prediction with monte carlo method to predict the needs of Rice Milling  Unit in the future. The results showed that rice production in 2013 to 2017 was increased so that the availability of Rice Milling Unit in subdistrict of Padangsidimpuan Hutaimbaru was unable to meet grinding rate, therefore steamroller should be created. Keywords: monte carlo , rice milling unit

Abstract

The decrease of fossil resources and increase population are very contradictive to energy consume for human life and social economy activity. So, alternative energy is needed which environment friendly by the use of plastic waste as fuel. This research as aimed to compare fuel from plastic (Polyethylene), cosmetic bottle (HDPE) and mineral water bottle (PET) with kerosene. This research was done in Agriculture Engineering Laboratory, and in Physical Chemistry Laboratory of  MIPA and Heat Engine Laboratory Faculty of Engineering in August 2014 until finish using completely randomized non factorial design with plastic (Polyethylene), cosmetic bottle (HDPE) and mineral water bottle (PET). The parameters analysed were yield, value of heat and viscosity. The results, showed that fuel nearly the same with kerosene was P2 (cosmetic bottle) with heat of 10.578,6 kcal/Kg and viscosity of 0,940 cP. Keywords : Plastic waste, Polyethylene, HDPE, PET
