Abstract

One of the important components in the process of spot welding or spot welding is electrode tip or better known as”eltip". The quality of eltip material will greatly determine the welding results, the level of reliability and service life of eltip. The purpose of this study was to analyze the characteristics of eltip and find a suitable formulation of locally produced eltip to replace imported eltip. The chemical composition of the eltip material that is currently used is unknown and is a secret for import manufacturers. Local production Eltip used spot welding process has a disadvantage in service life. For this reason, chemical composition tests, hardness tests, and metallographic tests were carried out on the tip electrode. In the results of spot welding metallographic test and tark test, the results showed a minimum nugget diameter of 3 mm for 1 mm thick welding plate, can be met between 3.22 mm to 3.52 mm by local eltip. The service life of local eltip as many as 2000 spots is approaching the service life of imported eltip as many as 2400 spots. A slight improvement in Pb levels as an anti-wear will increase the service life of this local eltip in subsequent use. With reference to the quality standards of the Weld, such as the dimensions of the nugget, and visual check welding surface defects allowed by the car manufacturer, the results of this study are expected to be a reference for the use of eltip in the welding process elsewhere.

Abstract

In the era of Industry 4.0, the integration of advanced technologies like the Internet of Things (IoT) into risk-based maintenance planning systems has become crucial for optimizing operational efficiency. This research explores methods to enhance maintenance decision-making by integrating real-time IoT data with risk-based maintenance models. Traditional risk-based maintenance often relies on historical data, which can be insufficient for responding to dynamic operational conditions. By leveraging IoT's ability to collect continuous, real-time data, this study aims to improve the accuracy and responsiveness of maintenance strategies. The research employs a systematic methodology, including data collection through IoT sensors, data preprocessing, and the development of predictive models using machine learning techniques such as Random Forest and Neural Networks. The results indicate that IoT integration reduces downtime by predicting equipment failures with higher accuracy, leading to a 30% reduction in maintenance costs and a 25% increase in productivity. This study demonstrates the significant potential of IoT in transforming maintenance strategies from reactive to proactive, ultimately enhancing equipment reliability and extending operational lifespan.

Abstract

The optimization of water distribution systems in high-rise buildings is essential for enhancing energy efficiency and reducing operational costs. This study examines the effects of implementing a Variable Frequency Drive (VFD) on a centrifugal pump system within a four-storey high-rise building at PT SBA. A case study approach was employed to measure key operational parameters—namely, electrical power consumption, water flow rate, and pressure distribution—both before and after VFD installation. The experimental results demonstrate that the VFD application resulted in a 20% reduction in power consumption, decreasing from 3.5 kW to 2.8 kW, while the water flow rate improved by 12.5%, rising from 80 LPM to 90 LPM. In addition, the pressure range was significantly stabilized, narrowing from 1.2–2.5 bar to 1.0–2.0 bar across the building’s floors. An economic analysis based on the observed energy savings indicates an annual cost reduction of approximately Rp7,665,000, with a corresponding return on investment achieved in less than one year. The findings suggest that integrating VFD technology into centrifugal pump systems not only enhances operational efficiency and extends equipment lifespan by mitigating load fluctuations but also offers substantial economic benefits. This study provides a robust framework for the broader application of VFD-based optimization strategies in high-rise and industrial water distribution systems.

Abstract

The purpose of this paper is to determine the number of proposed work stations based on Rank Positional Weight and to find out the results of the comparison between the initial work station conditions and the proposed work station conditions. The method used in optimizing Line Balancing is the Rank Positional Weight (RPW) method by calculating the amount of processing time, Balance Delay, Smoothness Index, the largest track efficiency, and station efficiency. The results of the comparison between the initial work station conditions and the proposed work station conditions using the RPW method in the total production process time of the S11038Z section from the initial conditions of 1060.23 seconds after analysis using the RPW method obtained a shorter processing time of 970.23 seconds or reduced by 90 seconds. The balance delay in the initial condition was 67.6% with the RPW method, the result was that the balance delay was better, namely 62.9%. The smoothness index in the initial conditions is 1059.79 to 857.88. The tracking efficiency increased by 4.7%, from 32.4% to 37.1%. The efficiency of the biggest workstations also increased, from 489 seconds to 399 seconds.

Abstract

Indonesia is one of the countries that have a fairly high level of consumption of fuel oil (BBM), based on data from BPH Migas (2018) throughout 2018 which reached 75 million kiloliters or an average of 1.6 million kiloliters per day. The consumption includes 16.2 million kiloliters of certain types of fuel (JBT), special types of fuel for assignment (JBKP), and general types of fuel around 51.3 kiloliters. The data is growing this study aims to measure the efficiency of reducing imports of fuel oil by utilizing solid waste of palm oil and to make proposals for the formulation of planning scenarios to optimize the functions of the Indonesian palm oil downstream industry. This research method combines quantitative and qualitative methods using the concept of efficiency and the Scenario Planning model. The method used in this paper is to calculate the level of efficiency using quantitative data on oil palm based on the amount of plantation area and the solid waste it produces. Then a mapping of the downstream palm oil industry will be carried out by reviewing the results of previous research as well as data and information obtained from accurate sources. The result is that by optimizing the utilization of palm oil solid waste, 7.4 billion liters of bioethanol can be obtained which can be used to produce biofuels to reduce the level of imports of fuel oil in Indonesia.

Abstract

This study evaluates the effectiveness of a laser marking machine in an instant noodle packaging line using a Total Productive Maintenance (TPM) framework and Overall Equipment Effectiveness (OEE) metrics over a 12‑month period. A mixed‑method design combined direct observation, semi‑structured interviews with operators and technicians, and a literature review to assess availability, performance efficiency, and quality rate. The machine achieved excellent availability, averaging 98.95%, reflecting the impact of preventive maintenance in reducing unplanned downtime. Performance efficiency varied substantially, ranging from 59.13% to 93.27%, indicating significant headroom for productivity improvement through cycle‑time stabilization and minor‑stoppage reduction. The quality rate averaged 89.21% and remained relatively stable, though still short of ideal benchmarks, suggesting the need for tighter in‑process quality control. The monthly OEE peaked at 84.77% in April, approaching the JIPM benchmark of 85%, while the period average was 60.38%, underscoring the need for sustained improvement initiatives. Among the three components, performance efficiency exerted the greatest influence on OEE due to its high variability across months.
