<![CDATA[The solid wastes of palm oil are palm shell and boiler ash which can be used as adsorbents. Adsorbent is a solid substance that an adsorption process which is used for the refining process of used cooking oil. Used cooking oil is oil derived from leftover cooking oil which has a higher saturated fatty acid content than new vegetable oil. This study aims to determine the process of making adsorbents, the process of refining used cooking oil, and the effect of adsorbent variations on the purification of used cooking oil. This research was carried out with the adsorption process, adding 15% of the adsorbent variation. The process of making the adsorbent was carried out by dehydration, carbonization at 6000C, and activation with 3% HCl for 24 hours. The results of the optimum adsorbent variation were 100% palm shell adsorbent with the results of analysis on used cooking oil after adsorption, namely: 0.05% water content, 0.58% ALB content, and 1.7 mgO2/100g peroxide number.]]>

<![CDATA[Biodiesel is an alternative diesel fuel made from renewable materials such as vegetable and animal sources. Used cooking oil is waste cooking oil that is often found in households, very easy to obtain and always available all the time. Used cooking oil can be used as raw material for making biodiesel because it contains triglycerides through a transesterification process with the addition of a base catalyst, one of which is the ash of empty palm fruit bunches. This research aims to determine the effect of adding ash from empty palm fruit bunches on making biodiesel from used cooking oil. The method used in this research is transesterification with the addition of a catalyst of empty palm fruit bunch ash varied at concentrations of 1%, 2%, 3%, 4%, 5% with a mole ratio of 1: 6 (oil: methanol). The tests on the biodiesel produced consist of acid number, viscosity and density.]]>

<![CDATA[An inventory information system is a system used to determine the stock of goods in a place or company. CV. Multikom is a company that operates in the field of computer equipment. In this company there are problems that occur in the current system, namely the processing of incoming and outgoing goods data, goods delivery data, and customer data that has not been integrated, as well as travel document data collection which is done only on a piece of paper and then copied to the computer by the warehouse admin, so that those who experience difficulties with the goods, the information provided is in accordance with the existing goods. The aim of this research is to design a Goods Inventory Information System to make it easier to collect data on incoming and outgoing goods, stock of goods, customer data, shipping, order transactions using the Prototype method and using Data Flow Diagrams (DFD) for structured modeling.]]>

<![CDATA[Based on historical data on the number of product requests and products produced in the January 2021-December 2022 period, there is a considerable discrepancy. Therefore to be able to predict demand in one or several subsequent periods based on past product demand data, the researcher conducts a forecasting analysis using the double exponential smoothing, moving average, and linear regression methods to find out the most accurate forecasting method to use. Based on the calculation results, it can be concluded that the most appropriate Forecasting method is the linear regression method because it has the lowest MSE value of 1,346,936,387. It is hoped that it will be able to assist PT Seiwa Indonesia in providing future stocks of RBL products in more accurate manner so as to reduce losses due to excessive production.]]>

<![CDATA[PT Sinarmar Distribusi distributes its products to all Distribution Center (DC) every day. Currently PT Sinarmas Distribution Nusantara uses a predetermined route every day using Colt Diesel Double vehicles with maximum transport capacity of 500 cartons. Currently the number of products carried by each vehicle never reaches its maximum carrying capacity. PT Sinarmas Distribusi Nusantara wants vehicle transport capacity to be used optimally. This route problem at PT Sinarmas Distribusi Nusantara can be defined as Split Delivery Vehicle Routing Problem (SDVRP). Ant Colony Optimization (ACO) is a metaheuristic that can be used to solve SDVRP. By using ACO the resulting route is always shorter than the current route and the number of vehicles used is smaller.]]>

<![CDATA[Data has become the most valuable component to be processed in order to provide usable information in the modern world of rapidly developing technology. When it comes to more in-depth or clear data analysis, technology is quite useful. Real governmental, social, and commercial operations use this technology; in the case of business, this is demonstrated by the quantity of minimarkets operating throughout Indonesia. As a result, it greatly increases commercial competition. Consequently, in order to compete, a study using the available data must be conducted. The Association Rule-Market Basket Analysis method was employed in this study to ascertain the shopping interests of the participants. According to the study's findings, two rules 60% (washing equipment and foodstuffs) and 62% (medicine and bottled drinks) showed the greatest confidence values. Based on these findings, the minimarket can decide what has to be done in terms of Product Bundling, setting up the layout and other tasks]]>

<![CDATA[Based on self-determination theory, this study identified the effect of servant leadership on the affective commitment to change of lecturers in Indonesian. This study empirically examined the specificity of the servant leadership construct when compared with other positive leadership constructs. The mediation effect of psychological ownership of lecturers was also examined. A total of 321 responses were analyzed using a two-stage structural equation modeling (SEM) approach to confirm factors and test the study hypotheses. The results showed that the level of servant leadership had a significant effect on psychological ownership, and servant leadership had a significant indirect effect on affective commitment to change only through psychological ownership of the lecturers. Research limitations and implications are discussed and future directions of research are suggested]]>

<![CDATA[The objective of this study is to investigate the performance of a horizontal shaft wind turbine model with variations in blade shapes. The focus of the research lies in examining the impact of different blade shapes, specifically the curved shape, inverted linear taper, and rectangular shape measuring 8 cm x 20 cm at a 200 tilt angle. The experiments are conducted at various wind speeds: 7, 8, 9, 10, and 11 m/s. The findings reveal that changes in blade shape significantly influence the operation of the horizontal shaft wind turbine. The Brake Horse Power (BHP) reaches its maximum with a rectangular blade shape, achieving 1.1 watts at a wind speed of 11 m/s and a corresponding torque of 0.0221 Nm. Additionally, the highest efficiency is attained with the rectangular blade shape at a wind speed of 7 m/s, reaching 21%.]]>

<![CDATA[MSME Cita Rasa is a manufacturing industry in Gorontalo City. Fulfillment of consumer demand for the quantity and time of orders is closely related to the availability of raw materials, labor, machines, working time and other resources that support bread-making production. Therefore, it is necessary to calculate the scheduling of capacity requirements for bread products to see available capacity and actual capacity. The aim of this research is to create a bread production plan and determine the feasibility of bread production capacity at MSME Cita Rasa using the Rough Cut Capacity Planning method. RCCP is a method used to measure work station capacity so that it can be seen whether a production schedule requires overtime work hours or subcontracts. Based on the results obtained, from the production capacity feasibility test using RCCP, it can be seen that all work stations in the MSME Cita Rasa have a positive value, which means the capacity is feasible]]>
