Abstract

Inverter-based Heating, Ventilation, and Air Conditioning (HVAC) systems are increasingly utilized in industrial settings for their superior energy efficiency and controllability. Despite these advantages, nonlinear switching in inverters generates significant harmonic distortion, particularly at lower-order frequencies such as the 3rd and 5th, which can compromise power quality, reduce system lifespan, and lead to non-compliance with regulatory standards. This study proposes a hybrid passive filter solution—combining a Double Tuned Filter (DTF) and a High Pass Filter (HPF)—to mitigate harmonic distortion in an industrial HVAC system. Field data collected using a Power Quality Analyzer (PQA) revealed a 3rd-order Individual Harmonic Distortion of Current (IHDi) of 12.9%, far exceeding the 4.0% threshold specified in IEEE 519:2022. The hybrid filter was analytically designed and validated through MATLAB/Simulink simulation. Post-simulation results demonstrated effective mitigation of Total Harmonic Distortion (THD) to 3.45%, with the 3rd-order IHDi mitigated to 3.42%, achieving full compliance with IEEE 519:2022. Furthermore, the hybrid filter preserved voltage waveform quality and suppressed high-order harmonics without incurring additional energy losses or resonance issues. The combination of DTF and HPF offers wide-spectrum harmonic mitigation and enhanced power system stability. This solution is well-suited for high-load, scalable infrastructures aligned with Industry 4.0 requirements. The study concludes that passive hybrid filters are a reliable and cost-effective strategy for harmonic suppression, and future work should explore real-time adaptive control and hybrid active-passive configurations for enhanced dynamic performance

Abstract

The hydram pump is a simple technology that utilizes the kinetic energy of water to pump water to a higher elevation without requiring external energy sources such as electricity or fuel. This technology is highly suitable for rural areas, especially in regions with limited access to electricity and other resources. Cikupa Village, Karangnunggal District, is one of the areas that utilizes the hydram pump to support water needs for horticultural activities. The Community Service Program (PKM) aims to ensure that the hydram pump continues to function optimally through a series of maintenance activities. The methods employed in this program include thorough inspections of the pump components, identification of damages, replacement of non-functional components, and post-repair operational testing. In addition, the PKM team also provides training to the local community on how to operate the pump, basic maintenance techniques, and the importance of regular maintenance to ensure the long-term sustainability of this technology. Outreach efforts are carried out to raise awareness among the community about the benefits of the hydram pump and its impact on their well-being. The results of the program show that the hydram pump was successfully repaired, restoring its ability to produce sufficient water flow to meet the community's needs. Furthermore, the community now has the ability to perform maintenance independently, ensuring the sustainability of this technology in the future

Abstract

The rapid growth of electric vehicle (EV) adoption has increased the need for reliable public charging infrastructure in urban areas. In Indonesia, public charging stations are generally supplied by grid electricity (PLN), which may increase operational costs and emissions depending on the grid generation mix. Integrating solar photovoltaic (PV) into electric vehicle charging stations (EVCS) offers a cleaner option. however, it requires careful consideration of both spatial suitability and techno-economic feasibility at the planning stage. This study proposes an integrated GIS-based planning framework to identify priority areas for solar-powered public EV charging stations in Denpasar City, Indonesia. The approach combines GIS-based spatial suitability analysis and comparative techno-economic evaluation within a unified planning workflow. Spatial analysis is first applied to screen candidate zones based on accessibility, land use compatibility, population density, proximity to activity centers, and solar energy potential. Subsequently, a techno-economic assessment is conducted to evaluate the feasibility of renewable energy–powered EV charging systems in the shortlisted areas. The results indicate that central urban areas and commercial districts emerge as priority deployment zones, driven by high accessibility, stronger demand indicators, and favorable techno-economic characteristics. Mixed-use residential areas are identified as complementary options to expand service coverage, while peripheral and agricultural-dominated areas show limited suitability for early deployment. The proposed framework demonstrates how integrating spatial screening and techno-economic considerations within a planning-oriented workflow can support more informed decision-making for sustainable EV charging infrastructure development in urban environments.
