Abstract

The cessation of the processing process at the palm oil mill will cause losses to the company, which can result inlow productivity of the plant. Damage to equipment at the palm oil mill requires more costs to repair the damage.For this reason, good maintenance is needed for each equipment used in the processing process using the normaldistribution method. In this study the tool used was Screw Press. The purpose of this study was to determine thevalue of Realibility and Maintainabiity by using a normal distribution and to determine the cause of damage to theScrew Press machine. This research stage was carried out by taking data on damage and repair of Screw Press inApril-June 2017 and processing data using normal distribution. The data needed in normal distribution is the valueof Realibility, Maintainability, and standard devisia. By doing this data processing, the Screw Press machine canoperate well with reliability value in April-June 2017 on screw press 1 machines at 98%, 98%, 99% andmaintainability value of 21.78 hours, 18.8 hours, 19 , 18 hours. Whereas in screw press machine 2 in April - June2017 the reliability value is 99%, 98%, 95% and the Maintainability value is 19.9 hours, 18.68 hours and 18 hours.

Abstract

Used cooking oil is oil left over from frying that can no longer be used for frying because it has decreasednutritional value and has a negative impact on health. Used cooking oil can still be used as an example as araw material for making soap after being treated with used cooking oil. This study aims to make soap fromused cooking oil as raw material after being adsorbed using activated carbon from oil palm shells. The stagesof this research are 1). Making activated carbon from oil palm shells, 2). Applying activated carbon frompalm oil shells to used cooking oil, 3). Making soap from used cooking oil that has been adsorbed withactivated carbon from oil palm shells and 4). Testing the quality of soap, namely moisture content, soapingnumber and foam quantity. The results showed that the characteristics of the soap produced with an averagewater content of 7.5% (SNI 196-206 Max 15%), Sapling Number 196.90 mg / gr (SNI 196-206 mg/gr) and theamount of foam 1, 58 ml. Soap made from used cooking oil as raw material that has been adsorbed usingactivated carbon from oil palm shells in accordance with SNI 196-206 mg/gr.

Abstract

Briquettes are solid fuels that can be used as alternative energy. This research aims to determine the optimalratio of raw materials with adhesive content at about 10% constantly. The stages of this research were asfollows: 1) Sampling of raw materials, 2) Drying and decomposition of raw materials, 3) CarbonizationProcess, 4) Milling. 5) Composition Treatment, 6) Pressing and quality analysis of briquettes. The data of thisresearch were obtained by measuring calorific value, moisture content, ash content, density, compressivestrength, and combustion rate. The ratio between empty bunch : bagasse respectively was depended on100%: 0%, 75%: 25%, 50%: 50%, 25%: 75%, 0%: 100%. The Parameters of treatments were calorific value,moisture content, ash content, density, compressive strength, and combusition rate to find out the bestparameters. The result of this research shows the that the combination of empty bunch and baggase gave theeffect to the qualities. The highest calorific value was showed in the ratio empty bunch : baggase (100% : 0%)with average HHV value; the lowest average of moisture content ; the lowest ash content; density;compressive strength value; and combustion rate respectively 5889 cal/gr; 2,81%; 20%; 0,941 gr/ml;1,82N/cm2;0,00223gr/second.

Abstract

V-Notch 900 is a device that has a triangular-shaped gap with an angle of ninety degrees. Tanjung Seumantoh Palm Oil Mill does not yet have a tool to measure the discharge of diluent water used at press stations, so there are often problems with the composition of crude oil that is not ideal due to too much or too little diluent water used. This study aims to determine the magnitude of the effect of using V-Notch as an indicator of crude oil diluent water regulation at Tanjung Seumantoh Palm Oil Mill PT. Nusantara I Plantation so that the comparison after and before Tanjung Seumantoh Palm Oil Mill using V-Notch at the press station is known. The results of this study show that the composition of crude oil before the application of V-Notch is 33:45:22 (Oil:Water:Nos) By using press number 3, 1 and 2 without knowing how much diluent water is used. After the application of V-Notch to 39:40:21 using pressan number 3, 1 and 2, it is known that the amount of diluent water used is 16.2 tons / hour. This indicates that the application of V-Notch can affect the composition of Crude Oil at the Press station to be ideal according to company standards. The oil content in palm fibers and palm kernel is 50%-55% and 40% respectively and the ideal crude oil composition is 40%Oil: 40%Water: 20%Nos.
