Abstract

PT X is a distributor of genuine and aftermarket spare parts such as batteries, tires, oil, and other components for various types of cars and trucks. Currently, PT X places orders only when the product inventory is very low or depleted without considering the optimal stock quantity. As a result, PT X often experiences stockouts when there is consumer demand, especially for tires and oil products, whose stock levels frequently fall below the company’s standard inventory levels. This study aims to address the issue of product availability for tires and oil by implementing an effective inventory control method. The methods used in this study include FSN analysis to classify inventory priorities based on their movement rate, Monte Carlo simulation to predict product sales in upcoming periods, and the determination of safety stock and reorder point to prevent future stockouts. The data processed in this study are the purchase and sales data of 25 tire and oil products during the period from March to August 2023, during which 25 products experienced stockouts. The results of the study show that by using FSN analysis, Monte Carlo simulation, and the determination of safety stock and reorder point, PT X can prioritize tire and oil products with high inventory turnover rates for special attention, optimize the inventory of tire and oil products by predicting future sales volumes, and reduce the risk of stockouts by determining safety stock levels and reorder points.

Abstract

Alvian MSMEs is a company engaged in printing, which serves ordering calendars, banners or billboards. The problem faced by Alvian MSMEs today is supply chain activities and production that are usually late so that products experience a decrease in buying interest from customers. To overcome these problems, MSMEs mitigate risks in supply chain and production activities using the HOR (House Of Risk) Method. Based on Hor phase 1, 12 risk events and risk agents were obtained. The identification results show that  the highest risk agent is low-quality raw materials (A9). This risk agent has the highest value because it can cause risk events in the form of poor quality or defects (E9). In HOR phase 2, 6 priorities were obtained for risk mitigation to prevent system failure (PA3), implementing preventive maintenance routines is a top priority. With an ETDk value of 10386, PA3 mitigation measures can reduce risk factors such as manufacturing defects, misconceptions of customer specifications, and quality testing problems, improper maintenance, overuse, system failure, technical problems with printing machines, staff or management failures, no routine monitoring of machine checks (A11,A8,A4,A5,A7).

Abstract

UPTD PAB (Regional Technical Implementation Unit for Clean Water Supply) Taluk Kuantan is a specialized unit established to operate the drinking water supply system (SPAM - Drinking Water Supply System). However, the provision of these services is not yet supported by an effective service system, both in terms of time and security. Where each customer is required to physically visit the UPTD PAB Taluk Kuantan office to obtain official information regarding the availability of clean water, which is typically provided in written announcements. In case of any issues related to water supply, customers must either visit the office in person or directly contact the personnel through telephone. To address this issue, a information system is required that can receive customer reports and convey information to customers. Additionally, a medium is needed that can coordinate customer data, resulting in more effective reporting. The research methodology employed in this research is Research and Development. In this research, the outcome is a service website for UPTD PAB Taluk Kuantan, resulting in an information system capable of receiving customer reports and conveying information to customers. This system can subsequently coordinate customer data, leading to more effective report generation.

Abstract

Sumenep Regency is the largest salt producing district on the island of Madura. However, the productivity of salt produced is still low. Therefore, this study aims to measure the salt productivity of the people of Sumenep, find out the factors that affect salt productivity, and provide recommendations for improvements to increase the salt productivity of the people of Sumenep. Productivity measurement uses  the Objective Matrix (OMAX) method which uses 5 ratios, namely land area, salt selling price, salt farmer group, quality salt 1 and quality salt 2. The next stage is to measure the value of productivity on each criterion, determine targets and weights using the Analytical Hierarcy Process (AHP) method, determine targets and calculate OMAX levels and analyze the productivity of salt production of the people of Sumenep. The results of productivity calculations using the OMAX method showed that the highest productivity index occurred in September at 572.319%, while the lowest productivity index occurred in August at -66.727%. Based on the traffic light system method, recommendations for improvement to increase ratio 4 (quality 1) and ratio 5 (quality 2) are by making tunnels or prism houses and the use of geomembranes that can increase salt production in quantity and quality.

Abstract

The purpose of this study is to use SERVQUAL and the Zone of Tolerance methodologies to evaluate daycare facilities. Research was carried out to comprehend the elements that impact the quality of childcare services to enhance the experience and happiness of service users. A quantitative descriptive-analytical technique was used. Questionnaires were sent to parents who used early childhood care programs to gather data. To assess the gap between customer expectations and perceptions of service quality, the obtained data was analysed using the SERVQUAL technique. The Zone of Tolerance approach was also used to estimate the degree of consumer satisfaction with the services delivered. Staff neatness and service costs/tariffs came out positively in the Servqual gap analysis (0.150 and 0.117, respectively). Two positive MMS value characteristics were produced using the zone of tolerance approach. The zone of tolerance encompasses two characteristics: the ability to respond quickly and efficiently while delivering services (0.017, -0.067) and the capacity to meet customers' unique requirements (0.017, -0.100). The sufficient service category includes five service qualities; if any of these are no longer acceptable to clients, the service must be corrected quickly.  Keywords: service quality, child care, Servqual, zone of tolerance

Abstract

Fulfilling maternal nutrition is an NP-hard problem. Optimization techniques are required to solve its complexity. This issue is crucial as it affects the number of stunted toddlers in Indonesia. Stunting begins in the womb due to inadequate maternal nutrition during pregnancy. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are optimization methods applied to NP-hard problems, including medicine. Their performance has not been compared in this field. This study aims to identify an alternative method for recommending daily menus based on maternal nutritional needs. There are 55 food ingredients used to fulfill five menu parts: staple food (SF), vegetables (VG), plant source food (PS), animal source food (AS), and complementary (CP). Nutritional adequacy for prenatal is determined by Total Energy Expenditure (TEE) based on basal energy, daily activity, and stress levels. Results show PSO outperforms GA in average fitness values, 30.45 to 102.51, while GA excels in execution time, 0.33 to 23.22 seconds. PSO is preferred for effectiveness, and GA for efficiency, but given the problem's urgency, PSO is recommended. Exploring other metaheuristic methods is advised to enhance menu recommendation solutions for maternal nutrition. Additionally, expanding the food database is necessary for more varied maternal menu to support stunting prevention.

Abstract

To maintain competitiveness and efficiency in the chemical manufacturing industry, particularly in large-scale continuous ammonia production, optimal labor management is essential. This study analyzes labor productivity in the ammonia production process at PT , specifically in the Ammonia 1A production unit, using the partial productivity measurement method. The primary objective is to measure the contribution of labor to production output and identify the factors that cause productivity fluctuations. The method employed compares ammonia output with labor input for the period of January to December 2024. In addition, downtime analysis and a fishbone diagram were utilized to evaluate the root causes of productivity decline. The results indicate significant fluctuations in labor productivity, with the highest value recorded in November (775.8 tons/person) and the lowest in September (412.79 tons/person). The decrease in productivity is attributed to labor shortages, equipment failures, and suboptimal work procedures. The average productivity index during the observation period was 97.17%, reflecting a decline compared to the base month. These findings provide a foundation for strategic recommendations to improve workforce management and enhance operational efficiency

Abstract

General elections are an agenda carried out to elect and determine leaders in each region. One of the important stages in the general election process is the vote-counting stage. This study aims to implement several digital image processing methods. Digital image processing plays an important role in the automatic reading of ballot papers to increase the speed of the vote-counting process. In this study, the process of reading ballot images was conducted to produce numerical data based on the coordinates of specific parts of the image. Image processing was performed using GNU Octave software, which is simple yet effective in detecting votes on ballot papers and converting them into numerical data based on centroid coordinates. This method has advantages in terms of implementation simplicity and computational efficiency. The main stages of this study include image conversion to grayscale, thresholding, black pixel detection, segmentation, centroid coordinate detection of punched ballot marks, and conversion into numerical form. In this study, 47 ballot image samples were used. The results of this study show that this method can achieve an accuracy rate of 78.7%.

Abstract

This study aims to analyze the effect of using fuels with different octane ratings (RON 92, RON 95, and RON 98) on the performance of a 206 cc four-stroke gasoline engine with a compression ratio of 12.7:1. The benefits of this study are to provide technical references for vehicle owners, repair shops, and automotive manufacturers in selecting fuel that matches the engine's compression ratio, as well as to raise awareness of the importance of using high-quality fuel to maintain the performance, efficiency, and durability of modern vehicle engines. Testing was conducted using a dyno test method to measure power, torque, and specific fuel consumption (SFC) at various engine speeds. The test data were analyzed using a quantitative descriptive method, comparing engine performance parameters with each type of fuel. The test results showed that high-octane fuel, such as Pertamax Turbo (RON 98), produced the best performance, characterized by maximum power, highest torque, and optimal fuel efficiency. Conversely, the use of low-octane fuel caused knocking, incomplete combustion, and increased the risk of deposit formation and corrosion due to its higher sulfur content
