Abstract

CV. Adi Makmur Metalindo is a metal manufacturing company with physically intensive work activities in its production area. Based on initial observations, the layout of the production area has not fully applied ergonomic principles, resulting in inefficient workflow and health complaints among workers. This program aims to analyze the existing layout conditions, redesign the production area based on ergonomic principles, and measure the impact of these changes on work efficiency and comfort. The implementation method includes field observations, measurement of distances and time between work activities, posture analysis using the REBA method, and layout redesign using the Systematic Layout Planning (SLP) approach. As part of the impact evaluation, pre-test and post-test questionnaires were distributed to 10 workers to assess their perceptions before and after the proposed improvements. The analysis results show that the new layout design successfully reduced travel distance and process time, as well as improved the placement of work tools that were previously inefficient. The questionnaire results revealed a significant increase in workers’ perceptions of workflow efficiency, posture comfort, and satisfaction with the layout—showing an average score increase of 1.4 to 1.7 points. In addition, the program also raised awareness among workers about the importance of ergonomics in the workplace. In conclusion, the application of ergonomic principles in the reorganization of the production layout had a positive impact on both work efficiency and comfort. This program can serve as an applicable model of ergonomic implementation that benefits other small and medium-sized industries in creating a more productive and sustainable work environment.

In the fresh vegetable distribution industry, maintaining product quality during transportation is a significant challenge, especially since vegetables are vulnerable to changes in temperature, humidity, and vibrations. This research developed an Internet of Things (IoT)-based vegetable quality monitoring system that utilizes sensors to measure temperature, humidity, vibrations, and GPS location during the distribution process. The system was designed using the Software Development Life Cycle (SDLC) method, which includes stages of analysis, design, development, testing, and maintenance. The monitoring tools consist of the GPS Neo 6m sensor, temperature and humidity sensor (DHT11), vibration sensor (SW-420), as well as the Node MCU ESP32 microcontroller and GSM SIM800L V2 modem. Data was collected during the distribution from Berastagi, Karo Regency, to Pusat Pasar Medan. The monitoring results showed a lowest temperature of 23.6°C and a highest humidity of 93% RH, which are within the safe range. The detected vibration was 94.22%, indicating a low vibration level, which did not cause mechanical damage to the vegetables. Therefore, this monitoring system is effective in maintaining vegetable quality during distribution, and the data obtained validates that transportation conditions did not negatively impact the horticultural products.

Abstract

Oil palm plantations require accurate and timely plant census data to support effective management decisions related to productivity, replanting, and maintenance activities. However, conventional manual census methods are constrained by long processing times, inconsistent data quality, and high susceptibility to human error. These limitations hinder the early identification of abnormal or missing palms and delay operational planning. To address these challenges, this study developed an integrated digital census system using a Web-based Geographic Information System (WebGIS), GPS-enabled Android mobile applications, and drone-based photogrammetry. The research employed the Waterfall Software Development Life Cycle (SDLC), consisting of requirement analysis, system design, implementation, testing, and maintenance. Spatial and non-spatial data were collected through field observations, interviews, GPS coordinates, and UAV imagery. The system was developed using PHP, MySQL, and GIS-based visualization tools, while mobile components utilized GPS navigation to guide field staff in locating abnormal trees. Analysis of census data revealed that 799 out of 47,404 trees (1.68%) were classified as abnormal or missing, a population loss that can significantly reduce potential yield. The GIS-based system demonstrated substantial efficiency improvements, reducing census duration from 7–8 months to 1–2 months in Observation Area 1 and from 4–5 months to 1 month in Observation Area 2. Drone photogrammetry enabled more accurate detection of canopy gaps and validated field measurements. System testing showed that all functional modules performed correctly, and User Acceptance Testing yielded a Cronbach’s Alpha value of 0.821, indicating strong user acceptance and instrument reliability. Overall, the integrated system enhances data accuracy, accelerates census operations, and supports site-specific management in alignment with precision agriculture principles. The results highlight the system’s potential to significantly improve operational efficiency and sustainability in oil palm plantation management.

Abstract

The main problem faced by PT. KPBN Belawan is the low level of efficiency of boiler machines due to the lack of scheduled and systematic maintenance. Currently, the applicable maintenance system is preventive and corrective, which is ineffective due to the lack of attention from management and machine operators. Therefore, it is important to introduce a more effective and efficient maintenance system to maintain the performance of these machines. One approach that can be adopted is Total Productive Maintenance (TPM), which offers a more comprehensive maintenance strategy compared to other methods. By focusing on employee involvement, reducing downtime, cost efficiency, improving machine quality, increasing machine life, and improving workplace safety, TPM emerges as a very relevant and effective strategy to improve operational performance in the tank storage industry. This study aims to propose the implementation of Total Productive Maintenance (TPM) on boiler machines to overcome various problems faced by companies that utilize boiler machines in their production processes. To analyze the problem, the observer will assess the extent of the change in the effectiveness of the boiler machine operation and perform the following calculations: Overall Equipment Effectiveness (OEE) analysis, OEE Six Big Losses analysis, and Pareto Diagram analysis. Based on the results of the study, the following conclusions can be drawn: Activities carried out on the boiler machine at PT. KPBN Belawan has produced an Overall Equipment Effectiveness (OEE) value of 68.31% from May to October 2024, which is still below the standard threshold. From this study, several recommendations are proposed for the company: 1. Continuous calculation of Overall Equipment Effectiveness (OEE) for production machines and equipment is needed to obtain the latest information for planning continuous machine repairs as an effort to increase production efficiency at PT. KPBN Belawan. 2. Measuring the effectiveness of the boiler machine using the OEE method requires further assessment and calculation to determine which of the Six Big Losses most significantly affects the decline in the effectiveness of the boiler machine.

Abstract

The project for the creation of the Life Conveyor at CV. Mabar Karya Utama is a strategic initiative aimed at enhancing operational efficiency and the company's competitiveness in the manufacturing industry. In the execution of this project, there are several key problems related to delays in completion and time management, which ultimately affect operational costs and production schedules. To address these issues, this research utilizes the Critical Path Method (CPM) as an analytical and planning tool to identify critical activities that determine the duration of project completion. The research is conducted using a case study approach at CV. Mabar Karya Utama through the collection of both primary and secondary data. Primary data is obtained through in-depth interviews with the project managers, technicians, and operational staff, while secondary data is collected from internal documentation and previous project reports. Data analysis is performed by constructing a project network diagram that illustrates the relationships between activities and identifies the critical path that has no time slack. As a result, any delays in activities that fall within the critical path can directly impact the overall project duration. The analysis results indicate that the application of the CPM method can pinpoint weaknesses in the initial planning, such as suboptimal resource allocation and the lack of synergistic coordination between departments. With this identification, management can efficiently take corrective actions, such as redistributing resources and establishing more appropriate activity priorities. Furthermore, the use of CPM also allows for real-time monitoring of project progress, enabling proactive implementation without frequent dialysis. The conclusion of this study states that the Critical Path Method has proven effective in enhancing the efficiency of project completion time for the Life Conveyor creation at CV. Mabar Karya Utama. The application of CPM not only aids in schedule control but also provides a clearer picture of the workflow process and identifies obstacles encountered during implementation. Thus, it is hoped that the company can apply the findings from this research as a foundation for future project management improvements, thereby increasing productivity and positively impacting the overall performance of the company. From the results of a study, several results can be concluded, namely: 1) The critical path method (CPM) can be applied in the Life Conveyor manufacturing project at CV Mabar Karya Utama by identifying project activities, as well as determining the sequence of work again, calculating the completion time of each task, and finding the critical path that determines the minimum project time. 2) There are 11 critical paths that affect the progress of this project A1 + B1 + B2 + B3 + B4 + F1 + F2 + G1 + H1 + H2 + I1 and the path that has the most influence is when paths B3 and B4 are accelerated for 4 days. 3) The project completion time was 27 days with a total crashing cost of Rp. 309,545,750., - with an optimization level of acceleration of work time of 12.96%.

Abstract

There are obstacles in the tapioca flour processing process at PT. Florindo Makmur, namely production capacity has not been utilized properly because the supply of raw materials and the public's interest in planting cassava affects tapioca production. The smoothness of the production process will not run smoothly if the control of raw materials does not match customer demand, therefore controlling raw material inventory is very important for the company. In order to meet the uncertainty of consumer orders. One step that can be taken so that smooth production continues to run optimally is to design good and correct raw material inventory control. Therefore, based on the considerations above, it is hoped that the company can build cooperation with suppliers. From this problem, the researcher conducted a problem analysis to predict whether the supply of cassava raw materials at PT. Florindo Makmur has a positive effect on its production process. To solve the existing problem, the following calculation analysis is needed: Linear regression method analysis, Partial Hypothesis Test (t-Test), Determination Coefficient Test (R2). Based on the research that has been conducted on the analysis of the problem to determine the effect of cassava raw material inventory on the tapioca flour production process at PT. Florindo Makmur, the following conclusions can be drawn: The results of the linear regression calculation in 2023 obtained a value of Y = -31.707 + 0.261X and in 2024 obtained a value of Y = -165.529 + 0.274X. The results of the partial calculation (t-test) in 2023 obtained a t-count value of 87,072 and in 2024 obtained a t-count value of 58,148. The results of the calculation of the coefficient of determination (R2) in 2023 were 99.9% and in 2024 were 99.7%. Based on the results of this study, PT. Florindo Makmur is expected to be able to determine the amount of safety stock that must be in the warehouse to anticipate a shortage of cassava raw materials and result in the production process being stopped for 1 or 2 days. PT. Florindo Makmur should work together with farmers to provide training on good cassava planting issues so as to provide good harvest results. This can maintain the availability of raw materials and the sustainability of the production process of PT. Florindo Makmur
