Abstract

Palm oil (CPO) is extracted from loose palm fruit which is released from the oil palm fruit bunches, either naturally or by boiling. Several factors affect the yield of palm oil in the oil extraction process, including the year of planting and the variety planted. This study aims to look at the yield levels of oil palm fruit based on the variety year of planting so that the actual value is known and the effect of the year of planting on the yield value of FFB can be identified. The method used in this study refers to MPOB (Malaysia Palm Oil Board) and NRCOP (National Research Center of Oil Palm) standards which consist of 6 (six) stages, namely FFB sampling, initial calculation of FFB, seeds, and mesocarp, measuring moisture content, mesocarp oil extraction, calculating the percentage of kernels and shells, and calculating the value of the FFB material balance. Based on the results of the TB material balance analysis, it is known that the young planting year does not fully produce a low yield of palm oil, this is because many influencing factors cannot be controlled and are variables that cannot be locked/determined. The results of the average material balance for all planting years for the dry extraction method showed a CPO yield value of 22.97%, testing showed the highest yield was in the 2002 planted year with 27% content and the lowest was in the 2015 planted year with 19.68%.

Abstract

Lack of waste management of oil palm empty fruit bunches and the lack of utilization of oil palm empty fruit bunches (EFB). Based on this, the researcher wants to use empty bunches as paving blocks that meet the quality standards of SNI 03-0691-1996 which include the requirements for appearance, size, compressive strength, and water absorption. This research was conducted for 3 months and the sample to be used was obtained from the Pagar Merbau Palm Oil Mill. Oil palm empty fruit bunches are obtained from the process of soaking with the chemical NaOH for a while so that the fibers do not get moldy. Empty bunches of fiber, water, cement, and sand are mixed and stirred evenly which is then printed on a 21.5 x 11 x 6 cm size mold. The research was conducted at the ITSI campus (Indonesian Palm Oil Technology Institute) Medan and the Civil Engineering Laboratory of the Medan State Polytechnic. This research is experimental. Variable testing using ANOVA test with a confidence level of 95% or with a significance level of 5% (α = 0.05). The results showed that the appearance and size of paving blocks with fiber composition of 0%, 5%, 10%, 15%, and 20% oil palm empty fruit bunches met the requirements according to SNI 03-1091-1996. There is a relationship between the weight of paving blocks and the fiber composition of 0%, 5%, 10%, 15%, and 20% of the compressive strength of paving blocks and there is no relationship between the weight of paving blocks and the fiber composition of 0%, 5%. , 10%, 15%, and 20% of the water absorption of paving blocks.

Abstract

Semi Virgin Crude Palm Oil (SVCPO) is a palm oil product that is processed from palm oil FFB raw materials which are treated using chemicals in the form of 60% etephon. The FFB is processed with simple tools and a short process, as well as minimum treatment with a modified temperature. This study aims to speed up the harvesting time of palm fruit from the bunch by using the application method and 12 hours of curing time to produce good quality oil. This research was conducted at STIPAP, precisely at the TPHP Process Laboratory. The time of this research was carried out from January to July 2021. This study used the Completely Block Design (CBD) method, by administering chemicals to the FFB raw material by injection and spray methods. The results of this study showed that the FFB removal efficiency ranged from 6.61- 11.44% and SVCPO had DOBI values ranging from 1.66-2.57 ppm, carotene ranged from 311- 1044 ppm, and vitamin E ranged from 409-897. ppm. The application of injection and spray affects the efficiency of sloughing off and the quality of the oil. It can be concluded that in this study the best method for slashing efficiency was the spray method and the injection method for DOBI, carotene, and vitamin E values.

Abstract

Palm oil processing in the Palm Oil Mill (PKS) is carried out by extracting the fruit flesh (mesocarp) of the oil palm fruit in the palm oil mill processing with a palm oil mill processing machine. Realizing the results of palm oil processing requires a machine that operates in good condition to produce the output the machine is following the desired achievement with good screw press machine performance without any problems experienced during processing. This research was conducted by direct observation of the state of the screw press machine and taking daily secondary data in the form of loading time data, total production, production targets, ideal cycle time, actual, cycle time, downtime, operation time, and problem data on the screw press machine for 6 months from June-November 2020 on 2 screw press. From the results of the study, it was found that the constraints that caused the low-performance value of the screw press machine based on the value of idling and minor stoppages and reduced speed which resulted in the machine often experiencing momentary stops and a decrease in rotation of the screw press every month due to the large capacity of the machine that was not following the capacity. factory and the condition of the machine and the lack of supervision and control in humans cause the machine to often experience a decrease in performance on the screw press machine. From the results of the analysis of the results carried out, it was found that alternative solutions to improve the performance of the screw press machine were caused by 4 factors based on the identification carried out using a cause-and-effect diagram by paying attention to the critical point of a machine caused by human factors, machines, materials and methods based on analysis. Screw press machine performance is based on the value of idling and minor stoppages and reduced speed.

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.
