Abstract

PT XYZ is a manufacturing company in the automotive sector that produces vehicles and their components. Its production process generates hazardous and toxic (B3) waste classified as fast moving due to its high volume and frequency. This study aims to determine the standard time for the management process of iron gram B3 waste at PT XYZ. Observations were conducted over 15 cycles, with time recorded at each stage using the stopwatch time study method and adjustments based on the Westinghouse technique. The study was carried out across eight stages of the B3 waste management process at PT XYZ, involving calculations of cycle time, normal time, and standard time. The analysis revealed that the total standard time for the entire process is 42 minutes and 18 seconds. Establishing this standard time supports improved efficiency, prevents waste accumulation, and creates a more structured waste management system that can be periodically evaluated.

Abstract

Inventory of finished goods needs to be planned and controlled regularly. Fulfilling customer demand whenever and wherever is the main purpose of the supply. This issue is related to production activities. Many companies use the Economic Production Quantity (EPQ) Model in determining the size of their lot productions. This model is able to show how to minimize total production costs by reducing inventory costs. Customer behavior at PT XYZ makes product delivery divided into 2 types. The first type, finished goods is sent continuously in small amounts called continue demand. The second type, products is sent between certain time intervals in large quantities called discrete demand. Basic EPQ Model’s parameters do not accommodate a system like this. In addition, PT XYZ requires rework for products that do not pass the quality test. Therefore, this research was developed to formulate EPQ model that can accommodate two types of demand, continue and discrete, as well as the existence of rework policy. This study tries to provide another approach in solving the derivation problem using the "Arithmetic-Geometric Mean" method. The results of this study will display a mathematical formulation to find the optimal production cycle time for PT XYZ. Numerical examples are discussed to show practical models.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are the backbone of Indonesia’s economy, yet many traditional businesses lack adequate financial literacy, particularly regarding the calculation of the Break Even Point (BEP), which is essential for determining the breakeven level and profit planning. This community service program aims to improve BEP understanding among MSME actors of Maco Adaik in Nagari Sungayang. The program was implemented from July to September 2025 at the Sungayang Village Hall using a participatory approach through interactive lectures, simulations, and group discussions based on real business data. Evaluation was conducted using pre-test and post-test with Likert-scale questionnaires to measure participants’ comprehension. The training results showed a significant improvement, with 70% of participants able to calculate BEP independently after the program. Analysis of Maco Adaik business data indicated that breakeven is achieved at 30 packages per month with a selling price of IDR 18,100, fixed costs of IDR 300,000, and variable costs of IDR 8,083 per unit. This understanding encouraged participants to develop more structured pricing and production strategies and raised awareness of cost recording. Social impact was evident through active community involvement and strengthened entrepreneurial capacity based on local potential. This program effectively enhanced MSME financial literacy and is expected to contribute to business sustainability. For further development, digital-based financial recording training and collaboration with BUMNag are recommended to strengthen business institutions and replicate the program in other villages.

Abstract

PT X is one of Indonesia’s cement companies operating three active plants: Plant IV, V, and VI. Production data from 2022 and 2023 indicate that Plant V achieved only 79% and 86% of its production targets, with high downtime resulting from a reliance on corrective maintenance. This study proposes a preventive maintenance schedule to reduce downtime using the Reliability-Centered Maintenance (RCM) method for controlling critical components and an age-based replacement model for minimizing downtime. The analysis identified eight critical components in Raw Mill Machines 1 and 2, with reliability improvements ranging from 14% to 58%. Implementation of the proposed schedule resulted in increased machine availability by 5.1% and 4.65%, and system reliability improved by 33.71%. These findings demonstrate that RCM-based preventive maintenance effectively enhances operational performance.
