Abstract

The smoke chamber used has a capacity of 3,420 kg with a rubber sheet smoking period of five days. Reducing the water content (moisture content) on the rubber sheet is used by heating it with a smoking system. For smoke chamber operations, the fumigation temperature used on the first day is 40 - 45°C, on the second day 45 - 50°C, on the third day 50 - 55°C, on the fourth day 55 - 60°C, and on the fifth day the smoking temperature was maintained at 60°C. FDF and IDF are two air distribution devices, where the FDF functions to blow the air into the smoke chamber and the IDF draws the air into the smoke chamber. The balance between exhaled air and that drawn out of the smoke chamber must be proportional. Too much airflow will collect in the smoke chamber and too much the air withdrawal will affect heat transfer. After installing the FDF and IDF tools, the smoking time is 4 (four) days, so the use of smoked wood (rubber stem wood) is reduced from 3.19 m3 (for 5 days of smoking) to 2.55 m3 (for 4 days of smoking). There is a saving of one operational day. Reducing the use of smoked wood has an impact on processing efficiency. Heat energy from smoking has also increased. Before the installation of the FDF and IDF devices, the amount of heat energy was 64,074 kcal/day (320,372 kcal in 5 days). After installing the FDF and IDF devices, they increase the amount of air / oxygen (O2) in the combustion process so that there is an additional heat energy of 9,461 kcal/day (47,305 kcal in 5 days). The total amount of heat energy produced is 367,677 kcal for 5 (five) days of smoking. FDF and IDF are two air blowers commonly known as blowers with their respective specifications: The FDF used has an electric power of 3 kilowatts (4 horsepower/hp) with a rotation of 1,420 rpm, while the IDF has an electric power of 7.5 kilowatts (10 horsepower/hp). hp) at 1,440 rpm.

Abstract

Oil palm processing is one of the factors that determine the success of an oil palm plantation business. The Palm Oil Mill (PKS) in the context of the palm oil industry in Indonesia is understood as the unit of extraction of Crude Palm Oil (CPO) and palm kernel from the Fresh Fruit Bunches (FFB) of oil palm. The Palm Oil Mill (PKS) is the most upstream processing unit in the palm oil processing industry and is a critical point in the economic life cycle of palm fruit in particular and the palm oil industry in general. The purpose of this study was to find out how much percentage of palm oil loss was contained in the dregs of the press and to find out the optimal conditions for the screw press. The high or low percentage of oil loss in the process that occurs is influenced by several factors, namely the condition of the working pressure on the screw press and the capacity of the diluent water. The average percentage of loss of palm oil in the pressing process obtained from the data is June 5.07% with the norm of losses of pressed waste oil of 0.64%, the average of July is 4.92% with the norm of losses of pressed oil of 0, 64%, and an average of 4.98% in August with a normal loss of 0.64% of pressurized oil losses.

Abstract

This research was conducted to determine the quality of particle board using the raw material of empty palm oil bunches with different compositions. Oil palm is a plantation crop that has an important role in Indonesia today. This plant is a plant that produces vegetable oil and its derivative products. The processing of Empty Palm Oil Bunches (EFB) into particle board as a strategy for utilizing solid waste from palm oil processing was carried out in March - June 2020. Quality tests were carried out to determine the water content, bulk density, and composition ratio of the best OPEFB-polyurethane resin for producing high-quality particle boards. The moisture content of the OPEFB fiber was obtained at 43.34%, while the maximum density and hardness of the Hardness Rockwell Scale B (HRB) can be obtained with a ratio of OPEFB fiber to resin (50: 50) 50% OPEFB and 50% resin with a bulk density of 186.70 gr/cm3 and hardness of 60 HRB. The water content affects the resistance and weight of the contents so it needs to be dried. While the high bulk density affects the particle density thereby increasing the hardness of the material. This research was conducted at the STIPAP Medan Soil and Fertilizer Laboratory and the Medan Industrial Chemical Technology Polytechnic Lab. This research was conducted in March - June 2020. This research was a descriptive study. The parameters observed were moisture content, hardness, and bulk density. The data obtained were analyzed descriptively. Based on research conducted, the greater the mass of the board, the higher the weight of the particle board. Meanwhile, the hardness of particle board is influenced by bulk density and moisture content of particle board.

Abstract

PT. Langkat Nusantara Kepong is one of the KSO companies engaged in the oil palm plantation business. In carrying out the operational activities of one PKS unit, PT. Langkat Nusantara Kepong is supported by more than 100 workers who interact directly with machines and other work equipment. Every workplace contains a high potential for hazards, so a prevention and control effort is needed to prevent work accidents. The occurrence of work accidents is caused by the actions of people who do not comply with work safety (unsafe actions) and environmental conditions or processes from unsafe systems (unsafe conditions). Hazard Identification Risk Assessment and Risk Control (HIRARC) is an effort to prevent work accidents and OHS risks. This research was conducted using a qualitative descriptive method which describes the identification and assessment of work risks. Data collection regarding identification and risk assessment was analyzed with HIRARC. HIRARC Results at PKS Gohor Lama PT. Langkat Nusantara Kepong that the highest number of risk levels is at the boiler station.

Abstract

In general, solid waste from the palm oil industry contains high organic matter, which has an impact on environmental pollution. Improper handling of waste will pollute the environment. Various efforts have been made to process and increase the economic value of palm oil solid waste. Palm oil waste is the residue from the oil palm plant which is not included in the main product or is a by-product of the palm oil processing process, either in the form of solid waste or liquid waste. Oil palm solid waste can be in the form of empty fruit bunches, shells, bfiber and palm fronds. This research was carried out as an innovation from the previous research process with a differentiator, namely palm fronds, which in previous studies used empty palm oil bunches as raw material. In this study, hydrogen peroxide was used as a factor to determine the quality of paper made from palm fronds. Bleaching is a process of removing the color contained in the fiber due to the presence of lignin in the pulp with the help of chemicals. With three different concentration treatments aimed to determine the difference in the degree of whiteness, grammage and moisture content of the paper. Based on the results of the analysis of variance, it showed that the effect was significantly different on the concentration of the bleach solution (H2O2) with a variation of the concentration of 8% on the grammage with the highest grammage of 4% and 6% concentrations, and also had the lowest water content but at a concentration of (H2O2) 4% and 6% have higher water content.
