Abstract

Fires in densely populated areas are often difficult to handle due to limited access for firefighting vehicles, especially in narrow alleys. This research designs and tests a quadcopter drone as a solution to help the firefighting process in hard-to-reach areas. The drone was designed using a polyamide fiberglass F450 frame, Sunnysky 1250kv brushless motor, 10-inch propeller, 2200 mAh LiPo battery, and Pixhawk control system. The research method involves 3D design, component assembly, and testing the drone's performance against power consumption with and without load. The test results showed that the drone was able to fly stably with a lift of up to 5.3 kg and a flight duration of 45 minutes and was able to carry a sprayer with a hose length of 7 meters. Average battery consumption was in the range of 47–57% per 5 minutes, depending on the load. The drone proved effective in assisting firefighting in areas with limited access.

Abstract

The integration of Distributed Generation (DG) into modern power distribution networks plays a vital role in enhancing operational efficiency and driving global decarbonization targets. However, capturing the full technical and environmental advantages of DG requires precise multi-objective optimization. This study presents a systematic literature review aimed at evaluating, synthesizing, and quantifying the methodologies used for power loss minimization and carbon emission reductions within radial distribution networks. Adhering to the PRISMA 2020 framework, a rigorous bibliometric and content analysis was performed using Publish or Perish (PoP) and VOSviewer. Out of 323 initially screened articles indexed in the Scopus database from 2017 to 2025, 112 peer-reviewed papers met the strict inclusion criteria and were comprehensively analyzed. The synthesis reveals that optimal DG placement utilizing swarm intelligence techniques—predominantly Particle Swarm Optimization (PSO) and Genetic Algorithms (GA)—consistently achieves substantial improvements, yielding active power loss reductions between 40% and 94% and annual greenhouse gas emission mitigations ranging from 25% to 65%. Bibliometric mapping highlights a mature focus on voltage profile enhancement and network reconfiguration, while critical gaps remain in standardizing dynamic hosting capacity and life-cycle assessment (LCA) frameworks for emissions. Although simulation-based optimization models show high technical maturity, they still require real-world validation. Future research must prioritize dynamic operational strategies under stochastic renewable uncertainty to bridge this implementation gap.

Abstract

In the electric power system, insulating oil plays a pivotal role in separating two or more electrical conductors with different voltages. This separation is crucial to prevent unintended electrical connections or sparks that could compromise the system's safety and integrity. Mineral-based insulating oil is disadvantageous because it is classified as a mineral oil. This classification indicates that the waste is non-biodegradable, meaning biological processes cannot break it down. This characteristic can hurt the environment. Therefore, alternative efforts must be made to use liquid insulation, such as environmentally friendly vegetable oils. Vegetable oils are unsuitable as insulating oils due to their high viscosity, low oxidation stability, and good lubricity. A proposed solution to reduce palm oil viscosity involves adding additives. The dilution process can be enhanced by incorporating various additives, including butylated hydroxytoluene and butylated hydroxyanisole. The present study utilizes the Megger OTS80Af to assess the breakdown voltage and viscosity of the subject material.

The dilution process can be enhanced by incorporating various additives, including butylated hydroxytoluene and butylated hydroxyanisole. The present study utilizes the Megger OTS80Af to assess the breakdown voltage and viscosity of the subject material. The experimental findings indicate that crude palm oil, when augmented with butylated hydroxytoluene and butylated hydroxyanisole, is deemed unsuitable for utilization as a transformer insulation medium. This determination is predicated on its inability to comply with the stipulated criteria outlined in SPLN 49-91: 1982, specifically the minimum breakdown voltage of 30 kV/2.5 mm for transformer insulation oil.

Abstract

Deviations in chiller temperature can introduce significant technical risks in latex-based manufacturing processes, including premature coagulation and material degradation that directly affect product quality and production efficiency. Monitoring the water temperature in the cooling system (chiller) is therefore a crucial component in maintaining product quality in the latex-based industry. This study designs a temperature monitoring system based on the Internet of Things (IoT) that is able to display temperature data in real-time and provide automatic notifications if the temperature exceeds the threshold. The main devices include the DS18B20 sensor, ESP32 microcontroller, and Blynk application as a user interface. Testing was carried out on three chiller units at PT Medisafe Technologies for 48 hours. The results showed that the system worked stably with a measurement accuracy level of ±0.5 °C and an average notification response time of 3 seconds. This system provides an efficient, flexible, and easily accessible monitoring solution via smartphone devices.

Abstract

Landslides are a persistent geological hazard, especially in seismically active and high-rainfall regions such us Lombok Island, Indonesia. This study addresses landslide susceptibility in Sembalun Bumbung Village, located within the Rinjani Area, by integrating ground displacement monitoring with multi-parameter spatial analysis. Advanced image processing techniques were applied to Sentinel-1A Interferometric Synthetic Aperture Radar (InSAR) data, specifically processed using Differential Interferometric Synthetic Aperture Radar (DInSAR) technique, to observe and quantify annual ground displacement from 2019 to 2024. Simultaneously, a landslide susceptibility map was developed through the analysis of five key environmental parameters: rainfall, rock type, slope gradient, land cover, and soil type; each weighted and scored based on their empirical contributions to landslide risk. The DInSAR analysis revealed annual ground displacement values ranging from 0.030 to 0.105 meters, with the highest rates detected at points T6 and T7 in Benyer Hamlet. The resulting landslide susceptibility map categorized areas into five susceptibility levels (very low, low, moderate, high, and very high). Notably, points exhibiting a very high susceptibility (e.g., T1 in Bebante Daya Hamlet, T2 in Jorong Utara Hamlet, as well as T6 and T7 in Benyer Hamlet) consistently correlated with the highest annual displacement values observed from the DInSAR analysis. This integrated approach offers a solid basis for targeted mitigation strategies, including enhanced monitoring, risk communication, land-use planning, and potential early warning systems.

Abstract

Based on data from the Central Statistics Agency, most land in Indonesia has experienced degradation. Total area of critical land in Indonesia reaches 9,681,356 hectares, much of which is utilized for plantation activities. One of the regions significantly affected by this condition is Aceh Province, where extensive plantation areas are dominated by ultisol soils. The soil in this area is characterized by acidic conditions, low organic carbon content (approximately 0.5–2%), and moderate to very low total nitrogen levels (<0.50%), indicating inherently low soil fertility. These conditions ultimately result in reduced crop productivity, highlighting the urgent need for sustainable soil amendment strategies that can simultaneously improve soil chemical properties, enhance soil structure, and restore long-term soil fertility.  To address this issue, the utilization of biochar derived from biomass waste, such as coconut shells, is considered a promising solution. Biochar has been widely reported as an effective soil amendment capable of mitigating soil degradation, improving soil fertility, and supporting sustainable agricultural systems. However, the effectiveness of biochar is strongly influenced by its physicochemical properties, which are determined by both carbonization conditions and activation methods. In this study, the use of NaOH as an alkaline activator is expected to not only increase biochar surface area and reactive sites but also contribute to soil pH adjustment, which is particularly beneficial for acidic ultisol soils. This study aims to directly evaluate the effect of NaOH-activated biochar on plant growth and analyze the characteristics of the resulting biochar based on SNI 7763:2024. The biochar was produced through a carbonization process with varying residence times of 30, 45, 60, and 75 minutes at a temperature of 300 °C, followed by chemical activation using NaOH solutions with concentrations of 1, 1.5, 2, and 2.5 N for 3 hours to obtain optimal biochar characteristics. The results demonstrated that NaOH-activated biochar had a highly significant effect on plant height. The application of activated biochar improved soil structure by enhancing texture and porosity, reduced soil acidity, and promoted root development, which collectively increased nutrient availability and uptake by plants. The best moisture content and pH were achieved at 75 minutes of carbonization with 2.5 N NaOH, reaching 8.88% and 9.5, respectively. The highest C-Organic content was obtained at 30 minutes of carbonization and 2.5 N NaOH concentration, which was 55.80%. The relatively high C/N ratio indicates that the biochar is highly potential as a soil amendment to enhance soil fertility and crop productivity. Overall, NaOH-activated biochar had a highly significant effect on plant height by improving soil structure and creating more favorable conditions for plant growth.

Abstract

This study aims to analyze the performance of a solar-powered hydrothermal reactor with a capacity of 1 liter, utilizing a parabolic solar collector in the heating process of rice husk. The use of solar energy as an alternative heat source is expected to reduce dependence on fossil fuels and support the development of environmentally friendly technologies. This research employs an experimental method with a quantitative analysis approach. Two variations of raw material mixing ratios were tested: a 1:1 ratio (1 kg of water: 1 kg of rice husk) and a 1:2 ratio (500 grams of rice husk: 1 kg of water). Each ratio was tested three times, monitoring parameters such as material temperature, pressure, ambient temperature, and solar light intensity over a period of 3 hours. The results indicate that the hydrothermal device can achieve a maximum temperature of up to 135°C and a maximum pressure of 36 psi. The highest average temperature was obtained at the 1:1 ratio, measuring 95.46°C, while the 1:2 ratio yielded 85.80°C, demonstrating a significant difference in heating effectiveness. The effectiveness of the solar collector is highly dependent on solar light intensity and weather conditions. This study concludes that the parabolic solar collector is effective as a heat source in small-scale hydrothermal systems and has great potential for application in the processing of biomass waste based on renewable energy in tropical regions.
