Abstract

This study investigates the dynamics of water level (TMA), electrical current, power, and battery voltage in a data loggerbased monitoring system designed for peatlands. Data collected from October 30 to December 4, 2024, highlight significant fluctuations influenced by environmental factors, load surges, and voltage disruptions. Scenario simulations, including changes in rainfall, sudden load increases, and voltage system disturbances, were performed to evaluate the system's operational efficiency and stability. The findings indicate that TMA is highly influenced by hydrological conditions, where a 50% reduction in rainfall significantly decreases TMA, impacting the stability of current and power. A 50% load surge drives the current and power close to the system's maximum capacity, while voltage disruptions lead to a 20% increase in current and a 20% reduction in power, revealing system imbalances. Energy efficiency remains stable under normal conditions (0.0022) but drops significantly during disruptions. The study underscores the need for integrating protective technologies, such as Automatic Voltage Regulators (AVR), Overcurrent Protection, and balanced load management, to mitigate risks and maintain system stability. Additionally, improved water management in peatlands contributes to stabilizing TMA and reducing environmental impacts on electrical parameters. This research highlights the importance of a holistic approach, combining technology, hydrological management, and data-driven simulations, for sustainable operations. The findings offer practical recommendations for system enhancement, risk mitigation, and the development of future energy monitoring tools. Opportunities for renewable energy integration are also explored to ensure long-term operational efficiency and environmental sustainability.

Abstract

This research aims to develop a prototype tool for measuring water level (TMA) in the peatlands of Central Kalimantan by utilizing renewable energy from solar panels and batteries as the main environmentally friendly power source. The system is designed based on the ESP32 microcontroller integrated with a submersible transducer sensor based on the hydrostatic principle to improve measurement accuracy and stability compared to ultrasonic sensors, which tend to be affected by temperature and humidity conditions. This device is also equipped with a data logger and IoT connectivity for real-time data monitoring through the Firebase platform, enabling remote supervision without the need for direct presence in the field. The research process includes the design of wiring diagrams and PCBs, physical assembly of components, system programming, as well as testing voltage, current, and power parameters to evaluate the efficiency and performance of the device's energy system. The test results show that the prototype is capable of operating independently, with a TMA measurement accuracy of ±2.5 cm and a high correlation between electrical parameters and system performance (R² = 0.94). This tool is expected to be an effective, cost-efficient, and sustainable solution for monitoring water surface levels in remote and hard-to-reach areas.

Abstract

An attempted crime refers to an effort to realize a criminal objective that ultimately fails. In Decision No. 3250/Pid.B/2021/PN Mdn, the perpetrator attempted murder by attacking the victim with blows and a knife aimed at the neck, causing life-threatening injuries. The act was halted when Sinuraya intervened, prompting the perpetrator to flee. The panel of judges imposed a five-year prison sentence; however, this study considers the punishment inappropriate, as sentencing must reflect the gravity of the offender’s actions. This research employs a normative juridical method with a descriptive-analytical approach. The findings indicate that the elements of attempted murder were fulfilled, including intent, commencement of execution, and interruption of the act due to external intervention. Thus, the perpetrator’s conduct constitutes a stopped attempt. Nonetheless, the five-year sentence is inconsistent with Article 338 in conjunction with Article 53(2) of the Indonesian Criminal Code. The proper sentencing calculation is two-thirds of the principal penalty for murder, amounting to ten years’ imprisonment. Therefore, the judicial decision should have more accurately reflected proportionality based on the form of attempted crime involved.
