Abstract

The sole purpose of this analysis was to discuss the broader picture of fire incidents that occurred in industry due to electrical faults. Nowadays, fire incidents in industries as well as in residential and commercial buildings are a common case. Local and international print & electronic media report fire incidents every day. The fatalities are remarkable and also caused extensive property damage, and undoubtedly, it can be mitigated upon consideration of a few factors. This article identifies the exact causes of electrical faults, investigating previous fire incident reports in various industries and other possible reasons. During the past decades, there has been a noticeable change in infrastructure and industrial development worldwide. Because of land shortage and improper planning, the number of high-rise buildings in the industry sector increases without maintaining electrical standards, increasing fire incidents, fatality rates, and substantial property damages. Though strong laws, national and international standards, and regulatory measures existed, accidents occurred regularly. Also, there is no significant guideline for electrical product quality, run time, and materials selection, which plays a major role in fire incidents. This report anticipates understanding the lack in the existing system, considerable findings for installations, and extending to further studies to find out proper remediation.

Abstract

The primary focus of this study is to develop a ground-mounted solar power generation system with the optimal tilt angle and inter-row spacing to generate electricity in Indonesia, specifically in Lhokseumawe City. The research involves conducting simulation tests using Meteonorm software for solar resource assessment. Additionally, the HelioScope software is employed for modeling the ground-mounted solar power generation system, analyzing the PV system's performance in terms of annual generation, system losses, and performance ratio, as well as studying the solar panel's performance, current-voltage, and power-voltage curves for varying irradiance levels. The Single Line Diagram (SLD) reveals that 12 strings are connected to each inverter, and the output power of inverters is combined using 20.0 A circuit interconnects. The efficiency of solar power generation systems is influenced by the tilt angle and interrow spacing. Based on the simulation results for all scenarios, it is concluded that the solar power generation system installed at 0° tilt angle with a 0.9-meter interrow spacing outperforms other solar power generation systems. This is attributed to the maximum total collector irradiance of 1731.6 kWh/m2 compared to other tilt angles. At 0° tilt angle, the annual production of the solar power generation system is 14.77 GWh, with a performance ratio of 80.6%. This research aims to provide valuable insights for energy system designers, planners, and investors, guiding the development of strategies for the implementation of solar power generation energy systems not only in Indonesia but also globally.

Abstract

The rapid development of cloud computing has a significant impact on increasing the workload on resources, which is often excessive and a major challenge in computing environments.  Load balancing is key to avoid overloading or underloading virtual machines, given the high user demand for service availability. There are several types of load balancing techniques, and this diversity poses its own challenges in selecting the optimal technique to address workload issues. This research presents a systematic literature review with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify various load balancing techniques for server clustering in a cloud computing environment. The purpose of this research is to review previous research on load balancing techniques for server clustering in cloud computing by categorizing based on problems, solutions, research methods, objects, and research results. Research that uses the experimental method will be reviewed again to categorize the research results based on the load balancing matrix, namely response time, make span, resource utilization, migration time, fault tolerance, throughput, and cost. Various publishers, such as IEEE, Elsevier, Springer, Wiley, MDPI and Hindawi were explored as data sources. The research conducted generates more information about load balancing techniques for clustering servers in cloud computing and allows other researchers to fill the current research gap.

Abstract

The power generation sector contributes to climate change. Mitigation efforts are essential to ensure that the commitment to limiting the global temperature increase below 2°C stays on course. One option is to retrofit an existing power plant with new technology that allows integration with renewable energy. This study examines the incorporation of solar energy systems into the operational processes of coal-fired power plants. Utilizing solar energy to substitute steam extraction from high-pressure feed water heater No. 7. This study analyzes the performance of the power plant before and after the retrofit scenario within both power-boost (PB) and fuel-save (FS) modes. Performances under different load conditions also investigated. The results reveal that the thermal efficiency within both FS and power-boost (PB) modes increased up to 2 % compared to the base scenario. In both power-boost and fuel-save (FS) modes, there is a notable reduction in specific fuel consumption, with power-boost mode experiencing a decrease of 15.05 g/kWh and fuel-save mode showing a decrease of 15.75 g/kWh. Thus, the decreasing coal consumption implies reduced CO2 emissions within both FS and power-boost (PB) modes by 4.69 % and 4,94 %, respectively. Results under different loads show that the solar percentage and the rise in solar-to-electricity efficiency with decreasing loads. When operated in fuel-save (FS) mode, the proportions of solar electricity at VWO, 100%, 75%, and 50% load rates are 5.23 %, 5.53 %, 7.76%, and 11.92%, respectively. Moreover, the LCOE for solar electricity for both modes is 0.0267 USD/kWh, with expected investment returns of 5.87 years.

Abstract

Developing industrial standard induction motor control devices is inseparable from the advantages and ease of implementation. Induction motor control has developed rapidly since the development of semiconductor technology, which allows for more efficient, flexible, and accessible settings. The third industrial revolution makes it easier to control induction motors by meeting device standards and data communication systems. The development of cloud technology and the industrial Internet of Things in the fourth industrial revolution makes it easier to quickly control multiple induction motors from various places. Industry-standard devices such as human-machine interface, programmable logic control, and inverters are used to determine the performance of multiple induction motors using a scalar method based on PID controllers with a mobile phone remote control. PID performance is analyzed under transient conditions by measuring the rise time value and overshoot percentage. Meanwhile, the parameters measured in steady-state conditions are the average steady-state error values. The parameters on the PID controller are adjusted intuitively. The parameters used in data collection consist of the first parameter with the value of  Kp=26,  Ki=14, and  Kd=12, and the second parameter with the value of  Kp=29,  Ki=15, and  Kd=0. The rise time value will increase along with the given speed reference. The overshoot percentage value depends on the speed reference and the PID parameter value. At the same time, the average steady-state error value is below 5% for almost all speed references under loaded and unloaded conditions.

Abstract

Savonius wind turbines have better performance in locations with varying wind directions compared to horizontal axis wind turbines. However, their drawback lies in their low performance coefficient. The main objective of this study is to investigate the optimal design of a vertical axis wind turbine of the Savonius type. The parameters investigated include blade thickness and blade arc angle. This study was conducted using computational fluid dynamics (CFD) simulations with SolidWorks software. The simulation results show that at various blade thicknesses, there are significant differences in the obtained power coefficient () values. At a blade thickness of 2 mm, the highest power coefficient () reached 0.38 with a blade arc angle of 130º. Meanwhile, a blade thickness of 3 mm showed a maximum power coefficient () of 0.41 at a blade arc angle of 120º. However, at a thickness of 4 mm, there was a significant increase with the highest power coefficient () reaching 0.45 at a blade arc angle of 110º. This indicates that the most efficient shape for a Savonius wind turbine is with a blade thickness of 4 mm, a blade arc angle of 110º, a blade spacing of 3 cm, and an overlap ratio of 0.42, providing a maximum power coefficient () of 0.45.

Abstract

This paper aims to analyze the integrated management of water, energy, and food resources within the context of the Water-Energy-Food (WEF) Nexus in Magelang Regency, Central Java, Indonesia. The focus is on the projections for electricity demand, water needs, and potential electricity production from microhydro power plants (PLTMH) by 2030. The methodology involved simulation models using the LEAP and WEAP software to create a conceptual management model that promotes sustainable resource use. Our findings project electricity needs in Magelang Regency to increase significantly, estimated at 79,626.3 MWh under the baseline business-as-usual scenario, 90,281.53 MWh for a moderate scenario, and 92,201.78 MWh under an optimistic scenario, with the moderate and optimistic scenarios representing increases of 13.38% and 15.79%, respectively, over the baseline by the end of the projection period. Concurrently, water demand is projected at 349,953,115 m³ under the baseline scenario and slightly less at 339,542,991 m³ considering the impact of the new Yogyakarta-Bawen toll road, with a variance of 3.07% between the scenarios by 2030. Additionally, the potential electricity production from the proposed PLTMH is projected at 590.67 MWh by 2030. These projections underscore the critical contributions of sustainable infrastructural developments such as PLTMH, which, despite regulatory support, have not yet been constructed in the regency. This research illustrates the need for robust planning and integration of sustainable practices within local governance to achieve the objectives outlined in the Sustainable Development Goals (SDGs), emphasizing the importance of sustainable and innovative solutions to meet future demand for these interconnected resources effectively.
