Abstract

Sidodadi Village is a village in the Batang Kuis sub-district, Deli Serdang Regency, North Sumatra Province, Indonesia. One of the businesses in Sidodadi village is the Home Industry for marketing betel nuts which was initiated in 2012 by Mr. Mahadi and his wife, Mrs. Yayuk Wulan Dari. From the survey results, it turns out that partners have several problems, including the lack of knowledge and skills possessed by partners regarding product marketing techniques. The marketing method used by partners is still conventional, namely offering products by conveying information about their products and trying to persuade consumers to want to buy. During the covid pandemic, like today, partners feel the sales of betel nuts are decreasing. Therefore, partners need several steps to be able to maintain the business that the partners have built so far. The step or solution offered to partners is to use internet services, namely by providing socialization on the use of blogs to increase the marketing of areca nuts owned by partners

Abstract

XYZ is a manufacturing company engaged in the production of red and white cement. PCC cement packaging uses the main machine, namely the Rotary Packer machine, the packaging depends on consumer demand. If consumer demand continues to increase, the packaging process will take place continuously without stopping, and on the contrary, if consumer demand decreases slightly, the packaging process will also take place less. The high downtime of the Packer 1 machine causes production targets to be achieved, delays in the distribution process, and non-productive activities for employees. Based on these problems, the calculation of the effectiveness value on the Packer 1 machine using the Overall Equipment Effectiveness (OEE) method. Which aims to determine the value of OEE (Overall Equipment Effectiveness) of the Packer 1 machine, to determine the comparison of the OEE value of the Packer 1 machine with international OEE values, and to determine the priority factors for repair and the root causes of problems and solutions. Based on the results of data processing, it can be concluded that the Packer 1 machine OEE value is 16.98% which is obtained from the Availability Ratio value of 49.48%, the Performance Efficiency Ratio of 30.04 and the Rate of Quality product of 100%.

Abstract

PT. XYZ is a palm oil factory (PKS) producing crude palm oil (CPO). PT. XYZ has not implemented an effective engine maintenance system. The maintenance system that has been implemented is corrective maintenance, which is making repairs when there is damage. In addition, it is also assisted with planned maintenance that is scheduled every week to clean production machines. Therefore it is necessary to identify machine components that are susceptible to damage (critical components) and it is necessary to take special care measures for critical machine components by implementing a predective maintenance schedule (Prevention). Simulation techniques, often known as Monte Carlo simulation, estimate reliability using sampling random scenario. Failure mode effect analisys (FMEA) is defined as a process used to determine the actions that should be taken to ensure that each physical item or a system can run properly according to the function desired by the user then based on data processing, replacement of the roller binding drum binding drum , angle iron welding, chain transmission component replacement, drum stopper bearing replacement. Replacement of the drum stopper bolt, replacement of the chain transmission part is very loose and the replacement of the iron is carried out in corrective maintenance (replacement of components after damage occurs). And the results at the lowest value on the thresher engine component are in the Loose Transmission Chain component, the repair rate is 0.5 hours and the number is 0.999737189. Based on the results of the analysis of numbers (availability), the highest number is found in Broken Elbow Iron with a repair rate of 3 hours and the number 0.999605833

Abstract

XYZ is a company engaged in the processing of palm oil into crude palm oil (CPO). In processing oil palm fruit, the digester machine is one of the machines that crush the loose fruit so that the pulp of the palm fruit can be separated from the nuts / seeds and this will facilitate the pressing process of the oil palm fruit in a screw press. Total productive maintenance (TPM) is a system that is useful in increasing factory productivity and the efficiency of company production by using machines / equipment effectively used to produce a product. The main purpose of implementing TPM is carried out through the overall equipment effectiveness analysis method to identify and types of damage to critical components that are the object of research and to increase the overall equipment effectiveness value as a performance measure of the results of this study. To determine the comparison of the overall equipment effectiveness value, the calculation of the effectiveness value of the digester machine is carried out using the overall equipment effectiveness method. Based on the results of data processing, it can be concluded that the overall equipment effectiveness value of the digester machine is 3.95%, which is obtained from the availability ratio of 41.24%, the performance efficiency ratio of 157.57 and the rate of quality product of 100%.

Abstract

Empty palm fruit bunch fiber reinforced polymeric foam has been developing as alternative engineering material. This material uses unsaturated polyester resin (UPR) as its matrics, and treatmented empty palm fruit bunch fiber as its reinforcement element. Environmental friendly blowing agent has been used to get foamy structure in this material. This material tested to get properties of density, tension strength, static compression strength, and foams distribution. The result of this research is that A composition has the highest density for 665 kg/m3, with tension strength 0.05 MPa, compression strength 6.802 MPa and elastic modulus 37.859 Mpa. Eventhough additon of fiber could decrease mass of material, but in other side it could decrease the strenght of material too.

Abstract

One of the points stated in the Montreal and Kyoto protocol (1897 & 1997) is the elimination of the use of R-22 refrigerant (HCFC-22) and changing it with environmentally friendly refrigerants. The alternative is hydrocarbon refrigerants, which have been known since the early 1920s in refrigeration technology with other natural working fluids such as ammonia and carbon dioxide. One of the hydrocarbon refrigerants used in this study is Musicool (MC), which is produced by Pertamina's Processing Unit III Plaju. The purpose of this study was to determine the comparison of electrical energy consumption of AC Split 1 PK using 3 types of freon, namely R32, R410A, and MC22. The variables measured in this study were the working pressure of the refrigerant at the intake side of the compressor, voltage, electric current, and the testing time for 1 hour. Based on the analysis, it is obtained that the average split AC electricity consumption using freon R32 is 711.85 W, using R410A freon is 746.17 W, and using MC22 freon is 429.80 W. 301.85 kJ / kg, using R410A freon of 206.77 kJ / kg, using MC22 freon of 349.16 kJ / kg. The COP and EER AC Split values ​​are average using the R32 freon the COP value is 3.71 and the EER is 12.64, using the R410A freon the COP value is 3.55 and the EER is 12.09, and using the MC22 freon the COP value is 6.14 and EER of 20.94.

Abstract

This study aims to determine the effect of differences in welding current by performing a Tensile test in order to obtain the values ​​of elastic modulus, strain, reduction and stress. In this study, the material used is the lowest carbon steel with a thickness of 10mm. The welding process is a metallurgical process for binding metal alloy joints which are carried out in a liquid state. From the meaning of this research, it is explained that the notion of welding is a local connection of a metal rod joint where heat energy is used either from the heat source of electricity or a gas burning flame.The material to be examined will be given a variation of welding current of 100Amper, 130 Amper and 160 Amper, which will be welded with a SMAW welding machine using E6013 electrodes with a diameter of 3.2 mm. the method used is the comparative testing method, so that the difference in tensile strength can be found in the three specimens with different welding currents. From the research conducted, the highest tensile strength results were obtained with the number 382.81 MPa on the 130 ampere specimen material. 160 ampere specimen with a yield of 341.94 MPa. And the lowest is a specimen of 100 amperes with a number of 309.28 MPa
