Abstract

PT. XYZ is a manufacturing company engaged in plastic packaging processing. The research problem is the high level of machine downtime that affects production output and the achievement of company targets. The data used in this study were downtime data from August 2025 to January 2026. Overall Equipment Effectiveness (OEE) was used to measure availability, performance, and quality, while Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) were applied to analyze machine reliability. Pareto diagrams and Failure Mode and Effect Analysis (FMEA) were used to identify the main causes of downtime and determine maintenance priorities. The results of this study are expected to support more effective maintenance strategies and improve production efficiency.

Abstract

Managing high volume product flows at Warehouse Telkomsel Bandung faces challenges due to uneven workloads, as demand forecasting has not yet been implemented to account for potential inventory levels in the coming period. Using a descriptive quantitative approach and 5 Why’s analysis, this study further examined historical data compiled by the company over an 18 weeks period. As a result, Single Exponential Smoothing (SES) method was selected as the best method because it has the lowest error rate and controlled validation results. It is recommended that the company implement thi SES method and update the data periodically to maintain forecasting accuracy in the next period.

Abstract

PT. XYZ is a manufacturing factory that uses a Lohia 1 Jumbo Bag machine to produce plastic sacks. This machine often encounters problems during operation due to maintenance that is still reactive (Run-to-Failure), which causes a lot of unplanned downtime. This study aims to evaluate the actual operational performance of the machine and propose the technically and economically best preventive maintenance schedule. The research methodology begins by combining the Overall Equipment Effectiveness (OEE) approach and Six Big Losses to determine the level of efficiency and identify the main causes of time wastage in the production line.

Abstract

This study aims to analyze the efficiency of the HOLD product production process using the Single Minute Exchange of Die (SMED) method at PT Kencar Sukses Investama. The research was conducted because the production process experienced high setup time, machine downtime, and a significant number of HOLD products, which reduced production efficiency and increased operational costs. The study used the Stopwatch Time Study method, Fishbone Diagram analysis, and SMED implementation to identify and reduce non-value-added activities. Data were collected through direct observation, production records, and operator performance assessments involving four production operators. The results showed that the Router process had the highest standard time of 15.38 minutes, while Bokaki reached 12.60 minutes. After SMED implementation, setup efficiency increased by 28.57% for Router and 28.50% for Bokaki. In addition, HOLD products and production costs decreased significantly. Therefore, SMED proved effective in improving production efficiency and reducing production waste.

Abstract

The utilization of wood waste as a raw material for particleboard is expected to reduce industrial dependence on solid wood. In addition, the use of synthetic adhesives that potentially produce hazardous emissions has encouraged the development of natural adhesives based on sago modified with citric acid and chitosan. This study aimed to evaluate the effect of variations in citric acid and chitosan addition to sago adhesive on the physical and mechanical properties of particleboard. The research stages included the preparation of sengon wood sawdust, formulation of sago adhesive, particleboard manufacturing, and testing of the board’s physical and mechanical properties. The results of the study showed that particleboard with adhesive composition with the addition of 5%, 10%, and 15% citric acid and 5% and 10% chitosan of the weight of sago met the SNI 03-2105-2006 for density, moisture content, and internal bond strength. The addition of citric acid improved the physical properties of particleboard; however, excessive concentrations reduced the mechanical properties of the board. FTIR analysis indicated that chitosan has the potential to enhance the mechanical properties of particleboard.

Abstract

Bitumen Plant Gresik operated by PT Pertamina Patra Niaga does not yet have a dedicated smoking area at its office, despite the oil and gas environment carries a high fire risk. This study aims to plan the smoking area construction using the Critical Path Method (CPM) supported by Microsoft Project to determine the duration, critical path, and total project cost. The data used cover 20 work activities along with their durations, predecessors, volumes, and unit prices. Results show the project duration is 59 calendar days (1 February to 31 March 2026), with three parallel critical paths covering foundation, column, roster, flooring, anti-heat sticker, decorative elements, and site cleaning. The total project cost reaches IDR 255,850,000 (excluding 11% VAT), with the largest share of 84.53% allocated to structural and architectural work. These findings may serve as a project control baseline in oil and gas industrial settings.

Abstract

PT. XYZ is a car mat manufacturing company in Surabaya facing challenges due to sharp, fluctuating client demands and uncertainties in material procurement. The bullwhip effect occurring within the company poses a high risk of raw material overstock mat, as well as stockout risks that can cause production downtime. This study aims to measure the existing bullwhip effect value, analyze material handling, and compare the effectiveness of quantitative forecasting methods under the Collaborative Planning, Forecasting, and Replenishment (CPFR) framework. Initial identification confirmed demand amplification, with bullwhip effect values of 1.349 in 2024 and 1.183 in 2025. Based on comparative accuracy testing for projecting the next 12 months' demand, the ARIMA (2,0,0) model was selected as the optimal method as it produced the minimum error value, with a Root Mean Squared Error (RMSE) of 2118.37 and a Mean Absolute Percentage Error (MAPE) of 7.93%. Utilizing this selected model, inventory control planning can be optimized, establishing the safety stock after forecasting at 3,978 units with a constant 1-month lead time.

Abstract

Goods distribution is an important activity in company operations, particularly in the bottled drinking water (AMDK) industry, as it affects delivery performance, operational costs, and customer service levels. This study aims to design and analyze distribution route optimization using the Saving Matrix method and the Nearest Neighbor algorithm to improve the efficiency of the company's distribution system. The results show that the implementation of the Saving Matrix method and Nearest Neighbor algorithm successfully improved distribution efficiency at AMDK K3PG Gresik. The total distribution distance was reduced from 296 km to 263 km, resulting in a distance saving of 33 km (11%). In addition, the total distribution operating cost decreased from IDR 1,535,300 to IDR 1,347,300 per day, achieving a cost saving of IDR 188,000 per day (12.2%). Therefore, the combination of the Saving Matrix method and the Nearest Neighbor algorithm proved effective in optimizing the distribution system, reducing operational costs, and improving delivery route efficiency.

Abstract

This study aims to design and build a rubber material mixing machine using an anthropometric approach to improve work time efficiency at CV. Nur Hidayah. The main problem faced is that the rubber material mixing process is still done manually, so it takes a long time, a large workforce, and has the potential to cause fatigue and the risk of work injuries. The method used in this study is an engineering design method with an anthropometric approach, namely adjusting the dimensions of the machine to the worker's body size to create comfort and work efficiency. The data required are worker data, worker anthropometric data, and cost data. The results obtained for the body measurements used include a standing elbow height of 101 cm, a forward arm reach length of 70 cm, a knee height of 51 cm, and a hand span length of 149 cm. Before the machine was installed, CV. Nur Hidayah still manually mixed rubber tacks with a process time of approximately 58 minutes. After the mixing machine was designed and implemented, the mixing time was successfully shortened to approximately 15 minutes.
