Abstract

This research aims to enhance the performance of the Random Forest algorithm in classifying big data within the Internet of Things (IoT) domain, specifically for detecting botnet attacks. The study utilizes the N-BaIoT dataset, comprising 150,000 instances of IoT network traffic categorized into normal and anomalous (botnet) data. To optimize classification outcomes, a preprocessing technique—the “remove frequent values” filter—is applied to reduce redundancy and improve computational efficiency. Model performance is evaluated using accuracy, precision, recall, and F1-score. Experimental results demonstrate that this filter improves classification accuracy from 99.976% to 99.998%, with precision, recall, and F1-score all reaching 1.000. Cross-validation was conducted to ensure the robustness of these results. These findings suggest that even lightweight preprocessing techniques can significantly enhance machine learning performance in IoT big data classification tasks.

Abstract

This study presents the design of an IoT-based volcanic gas monitoring system powered by solar energy. The system integrates H₂S and CO₂ sensors with an ESP32 microcontroller, transmitting data in real time to a cloud dashboard via MQTT/HTTP protocols. A 100–300 Wp solar panel generated an average of 21 V and 2.1 A (≈529 Wh/day), significantly exceeding the sensor’s energy demand of ≈24 Wh/day. Field testing at Mount Bromo recorded average concentrations of H₂S = 0 ppm and CO₂ = 599 ppm, which are below hazardous thresholds but require continuous observation. The results demonstrate that the system is energy-efficient, stable under variable conditions, and effective in providing early warning alerts, thus supporting volcanic disaster mitigation and aligning with SDGs 9 and 13.

Abstract

Pemanfaatan minyak goreng bekas sebagai bahan baku biodiesel merepresentasikan pendekatan strategis. Hal ini dikarenakan dapat pengelolaan limbah dengan optimal menjadi penyediaan energi berkelanjutan. Akan tetapi, peran durasi reaksi dalam mengendalikan keterkaitan antara efisiensi konversi dan mutu bahan bakar masih belum dipahami secara komprehensif. Oleh karena itu, kajian ini menguantifikasi pengaruh waktu reaksi yang mendasari fenomena trade-off antara yield  dan karakteristik fisikokimia biodiesel. Eksperimen dilakukan pada variasi waktu reaksi 45–90 menit dengan evaluasi parameter yield , densitas, viskositas kinematikaa, dan flash point. Hasil menunjukkan bahwa yield  maksimum sebesar 85,64% dicapai pada 45 menit, kemudian menurun hingga 74,34% pada 90 menit. Sebaliknya, densitas dan viskositas meningkat secara bertahap, sementara flash point mengalami penurunan. Tren ini mengindikasikan adanya pergeseran komposisi produk yang dipicu oleh dominasi reaksi samping, termasuk reaksi reversibel dan akumulasi senyawa antara. Temuan tersebut menegaskan bahwa waktu reaksi berperan sebagai variabel pengendali distribusi komponen dalam sistem, yang secara simultan memengaruhi efisiensi konversi dan kualitas bahan bakar. Berdasarkan evaluasi terhadap parameter yield , densitas, viskositas kinematika, dan flash point, rentang waktu reaksi 45–60 menit menunjukkan keseimbangan terbaik antara efisiensi konversi dan karakteristik fisikokimia biodiesel sesuai SNI 7182:2024. Secara konseptual, studi ini memperkuat pemahaman mengenai mekanisme trade-off dalam proses transesterifikasi serta menawarkan pendekatan optimasi berbasis keseimbangan antara kuantitas dan kualitas produk

Abstract

This research aims to design and develop an advanced monitoring system for solar cells, incorporating solar tracking technology and equipped with an energy storage protection system. In Indonesia, the substantial potential of solar energy remains underutilized, despite the country's advantageous equatorial location, which provides a solar radiation intensity averaging 4.5 kWh/m² per day. The proposed system in this study seeks to maximize solar energy capture by employing a tracking mechanism that aligns the solar cells with the direction of sunlight throughout the day. Additionally, the system is designed with an integrated protection feature to prevent battery overuse, thereby extending the battery's lifespan and ensuring efficient energy storage. The research utilizes an Arduino Uno microcontroller, Light Dependent Resistor (LDR) sensors, and an INA219 sensor module as the primary components for accurate measurement and real-time monitoring. The system's effectiveness is evaluated based on its ability to optimize solar energy reception and maintain the longevity and efficiency of the energy storage system. Experimental results demonstrate that the developed system significantly improves the efficiency of solar energy capture by the solar cells and provides robust protection for the energy storage mechanism. This study contributes to the field of renewable energy by offering a practical solution for enhancing solar energy utilization in regions with high solar irradiance, thus promoting sustainable energy practices and reducing dependence on non-renewable energy sources.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.
