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

Corn cobs are a cultural problem in the NTB region because they are very influential at post-harvest harvesting. Poor handling of post-harvest corn cobs is a very serious problem in the area. Where corn cobs are only used by the community in general, making corn cobs as a mosquito repellent, by burning corn cobs. Corn cobs are corn residues resulting from shelling seeds which contain potential compounds that can be biologically transformed into other compounds, namely lignin, cellulose and hemicellulose. For example, making corn cobs chopper as a tool in handling post-harvest results. The purpose of this plan is to produce an efficient corn cob chopping machine so that it is useful for the community in NTB. The results of observations from the previous tool and processing data will be used to make the design size of the corncob chopper according to the real conditions of the previous tool. The results of the calculation of the transmission system of the corn cob chopper showed that the rotation of the electric motor was 1 HP = 1400 rpm, the shaft diameter was 20 mm, the seat belt used type A with a length of 828.4 mm. The materials used in this corncob chopping knife are as follows: knife = stainless steel material, bearing = cast iron, vant belt = rubber, pulley = aluminum, shaft = S35C-D. From the results of testing the corn cob chopper, 2 kg was obtained in 5 minutes.
