Mesocarp or fruit flesh is the main component of the cultivation of oil palm which is extracted to Crude Palm Oil (CPO). The amount of CPO produced from processing in palm oil mills is influenced by the quality of Fresh Fruit Bunches (FFB). Some factors that influence the quality of FFB are the type of crossing, plant age, maintenance level and fraction of fruit maturity. Adequacy of nutrients N, P, K, and Mg play a role in fruit formation and are expected to increase levels of CPO. In connection with this matter, research on the relationship / nutrient correlation with CPO content is needed. This research was conducted in October 2017 - March 2018 in the field with land suitability classes S1 (Maradja Hill), S2 (Limau Mungkur), S3 (Bah Birung Ulu) and STIPAP LPP Medan Practice Gardens. Processing data with single and multiple linear regression. Leaf samples were analyzed with the Sochlet apparatus in STIPAP Processing Laboratory. In general, the average nutrient content of leaves N, P, K were the normal category and nutrient Mg, Cl were deficiency category. The level of CPO (oil / mesocarp) varies from 31.14% - 59.59%. With single nutrient regression N, P, K, Cl has a positive correlation with CPO levels while Mg is negatively correlated. Multiple regression analysis of nutrient N, P, K, Mg and Cl has significant effect on O / N with a correlation coefficient of 0.744.

Palm Oil Millprocessingfreshfruit bunches (FFB) into palm oil andpalm kernel. In an effort to maintain quality and improve productivity, one ofthefactors that must be considered is theproblem ofmaintenance of the facilities / production machine. This study discusses the causes and consequences caused by the breakdown occurred Sterilizer machine, particularly on HorizontalSterilizer and vertical Sterilizer. To get a machine that can be maintained keterandalannya needed a good concept. Total Productive Maintenance (TPM) is a good concept to realize this. This concept, in addition to involving all personnel in the company, also aims to take care ofall the production facilities ofthe company. The data used is the data breakdown Horizontal Sterilizer and Vertical Sterilizer during the months from July to September 2015. In addition, this study also discusses the performance ofmaintenance mills, taking into account the value Mean Time beetwen Failure (MTBF), Mean Time To Repair (MTTR), and availability machine, using data from the foreman daily recordfor the month ofJuly 2015 until September 2015. So that later will know the actual state o f the company's information about treatment systems, especially in Sterilizer whether good or bad. Horizontal Sterilizerresearch results in July availablity value of99.50%, 0.42 hours maintainability and reliability value of283.75 hours while Vertical Sterilizerseptember availablity value of 98%, the value o f the maintainability o f 1.7 hours and 126.95 hours reliability value indicating reliability good, availability andperformance meets the standard ofthe lower maintenance operator will be well andgood.

Palm oil is a vegetable oil intended for oleofood and oleochemical products. Consumption of products are increasing. This study aims to determine the quality characteristics measured through free fatty acids, peroxide numbers and color of palm oil that produced from higlands crop. Palm fruits used in this study were obtained from Bah Birung Ulu Estate North Sumatera owned by PTPN 4 with an altitude 850 meters above sea level. Palm oil that produced from highland crops have free fatty acids (FFA) that increase with the increase of fruits maturity. FFA at the initial phase of maturity and after maturity phase (over ripa) were 5%, 7.6%, and 8,7 % respectively. Peroxide numbers and color of crude palm oil were ﬂuctuating according to fruit maturity. The red color of crude palm oil at the beginning of fruit maturity will increase as the fruit maturity increases but will decrease over ripe phase.
