Abstract

Inventory control is an effort or activity carried out by an agency to make decisions so that the need for materials for production purposes can be met optimally with the smallest possible risk. PT Mekar Armada Jaya (MAJ) is a manufacturing company engaged in stamping and tools. Inventory in this company consists of raw materials, goods in the production process, and goods held for sale. Because inventory is stored in a warehouse, inventory and warehouse management are closely related. Warehousing itself is a component unit in the product supply chain. The warehouse functions as a place to store goods, until they are used in the production process. The purpose of this study is to analyze the application of the FIFO system to raw material inventory at PT MAJ. Data collection techniques used in this study are direct observation in the raw material warehouse, interviews with warehouse staff and the production department, and documentation studies on the inventory recording system. The analysis was carried out qualitatively and quantitatively by comparing conditions before and after the implementation of the FIFO method in several aspects, namely, the level of accuracy of stock recording, the number of expired or damaged raw materials, and the efficiency of raw material retrieval time. The implementation of the FIFO method for inventory control carried out by PT MAJ is by attaching a FIFO label that will experience a color change for each item and change of month, this is done to distinguish new or old inventory. Materials received are given FIFO tags with various colors based on the supplier. The shelves used to store materials are given wheels or plaques, so that when taking materials it is easier. After the goods have been affixed with FIFO labels that are in accordance with the picklist and have been placed in the staging area, a loading list is made to be loaded after which the goods are scanned for their serial numbers by the checker and are ready to be sent. From the results of the analysis, it was concluded that the FIFO method applied at PT. MAJ uses a Kanban system and provides FIFO tags for raw materials, and the control of the system is carried out by people in the PPIC department.Keywords: inventory, FIFO, raw material, label, PPIC

Abstract

Adequate drug availability is a crucial component of healthcare services at Community Health Centers. Drug shortages can disrupt services and reduce patient trust, while overstocking risks expiration and financial loss. The National Formulary (Fornas) serves as a reference for selected drugs to ensure treatment quality. However, its implementation in health facilities still faces challenges. This research aimed to analyze the conformity of drug availability with the National Formulary and the percentage of drug availability level at Y Community Health Center in 2024. The study applied a descriptive method with a retrospective approach. The population included all drugs available from January to December 2024, with a total of 94 types, using total sampling technique. Data were collected from drug stock cards and monthly drug usage reports (LPLPO). Data analysis was performed by comparing the drug list with the National Formulary and calculating drug availability levels based on stock coverage time. The results showed that the conformity rate of drug availability with the National Formulary was 98.94%. Meanwhile, the percentage of drug availability level was categorized as 36.56% insufficient, 24.73% safe, and 38.71% excessive. It is concluded that drug availability at Y Community Health Center has not met the standard indicator of 100% conformity with the National Formulary and 100% safe availability level. This condition indicates inefficiency in drug management planning, which can disrupt rational drug use. Improvements in drug planning and monitoring are recommended

Abstract

The advancement of Artificial Intelligence (AI) has accelerated digital transformation in the recruitment process through automated candidate data analysis. This study aims to develop a prototype of an intelligent recruitment system by integrating ChatGPT (OpenAI LLM), N8N (workflow automation framework), and Supabase (PostgreSQL-based vector database). The proposed system automatically analyzes job seekers’ Curriculum Vitae (CV) stored in Google Drive and transforms them into vector representations using AI embedding models. These vectors are then utilized to match candidate profiles with corresponding job requirements. N8N functions as a workflow orchestrator that connects data sources, AI models, and the Supabase vector database. ChatGPT serves as an interactive agent that enables recruiters to perform conversational analysis and information retrieval based on vectorized data. This research develops an intelligent recruitment prototype by integrating ChatGPT, N8N, and Supabase to automate CV analysis and job matching through vector embeddings. The system extracts CVs from Google Drive, converts them into high-dimensional embeddings, and stores them in Supabase for semantic similarity search. Quantitative evaluation using ten candidate datasets shows an average processing time of 25.6 seconds per batch and a 0.81 relevance score compared to manual screening. The results indicate that AI-driven automation can enhance recruitment efficiency and accuracy by reducing manual effort and bias.

Abstract

Product damage is a common problem in storage and distribution processes, particularly due to impacts, temperature fluctuations, and uncontrolled humidity. Limitations of manual inspection systems often result in inefficient and non–real-time damage detection. This study aims to design and develop an Internet of Things (IoT) system based on Android for automated and integrated product damage inspection. The proposed system utilizes sensors to detect physical parameters that may indicate potential damage, such as vibration and environmental conditions. Sensor data are transmitted wirelessly to a server and presented through an Android application, enabling real-time monitoring of product conditions. The research methodology includes hardware design, software development, and functional system testing. The experimental results demonstrate that the system is capable of detecting and displaying indications of product damage with good reliability and fast response time. Therefore, the developed system is expected to improve monitoring efficiency, reduce the risk of product damage, and support more accurate decision-making.

Abstract

Reactive dyeing processes generally exhibit a relatively low fixation efficiency, ranging from 50% to 70%, which results in approximately 35% to 35% of the dye being discharged into the dyeing wastewater. In this study, cotton fabric was treated with a cationizing agent, CHPTAC, at a concentration of 5%, combined with different NaOH concentrations of 15%, 25%, and 35% relative to CHPTAC, using the exhaust method. The dyeing process was carried out using color Red Type A(vinyl sulfone type) and color Red Type B (monochlorotriazine type) reactive dyes. The results indicated that the cationized cotton fabric exhibited higher dye uptake compared to the untreated fabric. This improvement was confirmed by FTIR analysis, which showed the formation of N–H functional groups within the wavenumber range of 1580 cm⁻¹ to 3490 cm⁻¹. Furthermore, the color strength (K/S value) for vinyl sulfone dyed fabric increased from 1,65 for non-cationized samples to 3,31 for samples treated with 5% CHPTAC and 35% NaOH. Similarly, in monochlorotriazine dyeing, the K/S value increased from 2,04 for untreated fabric to 4,07 after the cationization process. The rubbing fastness test demonstrated satisfactory results, with dry rubbing values in the range of 4–5 and wet rubbing values between 3–4 and 4–5 for both vinyl sulfone and monochlorotriazine reactive dyes applied to 100% cotton fabric

Abstract

This study explores the potential of corn cobs as an alternative raw material for environmentally friendly tissue paper production. Corn cobs are rich in cellulose but contain lignin, which must be removed through a delignification process. In this research, soda delignification was applied with varied durations (30, 60, and 90 minutes), combined with the use of dextrin as a binding agent at concentrations of 5%, 10%, and 15%. The resulting tissue paper was evaluated based on Indonesian National Standards (SNI), focusing on tensile strength, water absorbency, sheet integrity, and grammage. The results showed that a delignification time of 60–90 minutes combined with 10–15% dextrin produced the best quality tissue paper. The sample treated for 60 minutes with 15% dextrin exhibited the highest tensile strength (400 N/m), while the sample treated for 90 minutes with 5% dextrin achieved the highest water absorbency (114 mm/10 minutes). These findings indicate that corn cob waste holds significant potential as a sustainable raw material for tissue paper production, supporting green manufacturing principles and agricultural waste valorization.

Abstract

Queueing problems at service facilities often lead to long waiting times during peak hours. At the Bank Jateng service counter located at Univet, which serves both students and surrounding residents, queue congestion frequently occurs at the beginning of the month and during certain service hours. This study aims to analyze the queueing system at the Bank Jateng Univet Office using a single-channel, single-phase (M/M/1) queueing model. The analysis was conducted using WinQSB software based on primary data collected through direct observation during operational hours and interviews with bank staff. The results show that the average customer arrival rate (λ) was 23 customers per hour, while the service rate (μ) was 26 customers per hour. The average number of customers in the system (Ls) was 11 people, with an average queue length (Lq) of 10 people. The average time spent in the system (Ws) was 0.5 hours. The service facility utilization rate (ρ) reached 88.46%, indicating a high workload level. Although the system operates under stable conditions, service capacity improvements are recommended to reduce waiting times during peak periods.
