Abstract

One of the bottled water industries in West Sumatra experienced an imbalance between supply and consumer demand, so this became a factor of difficulty in determining the period and quantity of orders for 220ml packaging materials, which resulted in the industry often experiencing shortages. and excess raw materials. So the Economic Order Quantity (EOQ) method will be used to determine the amount of inventory that needs to be ordered at the minimum cost or the optimal level of purchasing 220 ml cup packaging material. According to the company police, the inventory of 220ml cups per order is 2,117,346 pcs and the frequency of purchasing 220ml cups in a year is 24 times, while using the EOQ method, the inventory of 220ml cups per order is 3,969,012 pcs and the frequency of purchasing 220ml. cup in a year is 13 times. An additional suggestion after carrying out the investigation and finding out the inventory problem is for the industry to apply the Economic Order Quantity (EOQ) method in controlling the inventory of 220 ml cups because it can save costs related to inventory. The industry also needs to take into account the amount of safety stock and the original order point to avoid the risk of running out or excess raw materials. This is so that the company will continue to produce if the raw materials ordered take a long time to reach the factory.

Abstract

CPO is a crude oil obtained by extracting the palm fruit’s skin. CPO still contains both soluble and insoluble impurities in the oil. The purpose of palm oil purification is to efficiently convert crude palm oil into high-quality edible oil by removing undesirable impurities to an acceptable level. This also means that the loss of desirable components should be minimized. The refining process, which transforms crude palm oil (CPO) into edible oil, includes degumming, bleaching, and filtering to remove gum and unwanted components. In the Niagara filter, oil losses often occur, where the lost oil is usually discarded with SBE (Spent Bleaching earth). The extent of oil losses also affects the yield of RBDPO. Therefore, it is necessary to analyze total oil losses in the Niagara Filter process and identify the factors influencing these losses. The analysis results show that oil losses in SBE are directly proportional to the dosing of BE (Bleaching earth) in the bleaching process. The highest oil loss value in the Niagara Filter was 0.180%, while the lowest was 0.129% (company standard <0.14%). High oil losses can negatively impact the yield of the produced oil.

Abstract

Torch ginger (Etlingera elatior) contains secondary metabolites that have antibacterial potential. The production of torch ginger extract in Indonesia is still limited. However, market demand increase because pharmaceutical industry is starting to use the torch ginger extract. Furthermore, the growing utilization of torch ginger will enhance the economy of torch ginger farmers. This study aims to compare the extraction efficiency of maceration and soxhletation methods in obtaining bioactive compounds from torch ginger using ethanol, methanol and n-hexane as solvents. The results showed that in the maceration method, ethanol solvent produced the highest yield of 15%, methanol 7% and n-hexane 3%. In soxhletation method, ethanol and methanol solvents produced yields of 15% and 13% respectively, higher than n-hexane only 1%. Overall, soxhletation method with ethanol solvent was the best condition for torch ginger extraction. GC-MS characterization showed the presence of bioactive compounds such as 2-Chloropropionic acid, Boric acid trimethyl ester, Silane dimethoxymethyl and Octadecanoic acid methyl ester which contribute to the antibacterial activity in torch ginger essential oil.

Abstract

One of the palm oil processing industries in West Sumatra, in relation to meeting customer demand, experienced internal problems related to kernel quality, where there was inconsistent water and dirt content in the kernel. This can be seen from the analysis data on the water content and seed dirt in April 2021 which did not meet the quality parameter standards based on the Indonesian National Standard (SNI) 01-0002-1987, which is a maximum moisture content of 8%, maximum. dirt content of 6% and maximum broken seeds of 15%. Production analysis is carried out to measure kernel quality in the industry using the Seven Tools method (Histogram and Control Map) to improve the problems faced by the company as well as workplace maintenance to produce improvements and improve the quality of the products produced. The kernel quality level produced meets the standards set by the national standardization body, where the kernel quality level is a water content of 7.60% and an impurity content of 4.58%. In the process capability analysis, the Cp value is 1.11 for water content and 1.10 for dirt content, where a value of 1 < Cp < 1.33 means that the process capability is good, but more control is needed if the Cp value approaches 1.00.

Abstract

The problem faced by the Company is the absence of special arrangements applied to chemical warehouses in the storage or collection of warehoused products, so that the pattern of storage and the preparation of chemicals is randomized depending on the vacant warehouse position. Consequently longer transport times and long travel distances (there is a search process) and over pumping of goods. The purpose of this research is to get the design of chemical layout in the warehouse, to know the need of floor area and to know the total distance in the existing condition and the proposed condition. The method used is dedicated storage which is also called as a fixed storage plot for each product type. In this method the placement is based on the ratio of throughput and space requirement (T/S) with the largest T/S placed on the block with the distance between each block of smallest. From the calculation results obtained the total distance traveled at this time that is equal to 783.9 m and calculations on the proposed conditions obtained for 456.6 m, which means a decrease in total travel distance of 38.20%.

Abstract

In 2021, the quality of kernels in one of the palm oil processing industries in Riau was found to exceed the set standard limit. This is of course a problem that can affect the quality of the product. So kernel quality control will be carried out using the DMAIC method (Define, Measure, Analyze, Improve, Control). From the results of the X water content control chart above, it can be concluded that the data is said to be abnormal because some of it exceeds the UCL. While in the control map R there is data that exceeds the control limit or is uncontrolled. This is because the difference in sample values has such a large distance. From the results of the X temperature control chart above, it can be concluded that the data is said to be abnormal because the data exceeds the LCL or UCL. While in the R control map there is data that exceeds the control limit or is uncontrolled. This is because the difference in sample values has such a large distance. The cause of the high level of impurities in the core. The use of Pareto diagrams to determine the cause of non-compliance with quality standards in kernels is due to the highest/dominant impurity content. The causes of non-compliance with kernel quality standards are due to machine and human factors such as damage to claybath and hydrocyclone machines and lack of SOPs being followed.

Abstract

Activities in carrying out work often make workers feel tired, especially work that requires continuity, skill and concentration. Work activities like this can be quite burdensome for mechanics, which can cause fatigue or injury to workers. On the other hand, a workload that is too light can cause workers to become bored or bored with their work. The aim of this research is to determine the workload in each division area studied, and to estimate the right number of workers for a particular position so that it can be a recommendation for companies regarding workload. The Full Time Equivalent (FTE) method is a method for measuring workload by measuring the length of time needed to complete a given task. After carrying out the calculations, the FTE index values are obtained as follows; 1) The press station mechanic is in the 4.39 category (overload), indicating that 2 more employees are needed. 2) General installation mechanics of 0.34 category (underload). This indicates that there is no need for additional employees, but perhaps a reduction in employees to 1 person. 3) Workshop mechanics amounted to 3.63 in the category (overload). This indicates that 2 more mechanics are needed. 4) Mechanical electrical installation is 0.45. This indicates that there is no need for additional mechanics in this area. By calculating the FTE method, it can be seen that there are 2 divisions that fall into the overload workload category, and 2 divisions that fall into the underload workload category. The results of this research are quantitative and from a macro perspective, so it is necessary to also consider socio-cultural factors with employment regulations.

Abstract

The 5S concept (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) is a workplace management method aimed at improving efficiency, safety, and production quality through sorting, organizing, cleaning, standardizing, and instilling good work habits. This study was conducted at PT XYZ, a palm oil processing company, with the objective of evaluating the implementation of the 5S method. The study found that the company’s application of the 5S concept was still relatively low, particularly in the aspects of Seiri, Seiton, Seiso, and Seiketsu. Key challenges included material piles, lack of cleanliness in the production area, and minimal maintenance of machinery and equipment. To address these issues, various improvement proposals were made, such as regular workplace cleaning, better material organization, and employee training to enhance responsibility and work discipline. Following the implementation of these proposed improvements, the assessment score for the 5S method increased from 40% to 75.55%. The results of this study indicate that the proper implementation of the 5S method can improve production efficiency, product quality, and workplace safety, with positive impacts on the overall performance of the company.

Abstract

One of the industries in South Solok is a manufacturing company engaged in the Palm Oil Processing (PKS) industry. In order to maintain the quality and excellence of its products, this company must carry out more maintenance and monitoring of the smoothness of its production process. One of the more maintenance that must be carried out in this industry is maintenance of the screw press machine which often experiences obstacles during production, if a problem occurs with this machine, the processing process at the next station will be disrupted and can even stop operating. After conducting interviews with field supervisors, it can be concluded that screw press machines often experience problems such as stopping while operating due to less than optimal maintenance, and the age of the machine is old.
