The rise of renewable energy has led to growing interest among researchers in optimizing renewable energy systems to harvest the highest possible energy output, especially in photovoltaic (PV) systems. Photovoltaic systems generate energy from sunlight, but the intermittent nature of sunlight poses a challenge for providing constant power. Another problem is that the most affordable conventional Pulse-Width Modulation (PWM) controllers on the market are unable to provide a current monitoring system. This issue is critical when users require detailed data to perform diagnostics on their PV systems. In this study, a monitoring system using microcontrollers and the ACS712 current sensor was developed and implemented to observe the behavior and performance of a photovoltaic (PV) charging system based on the current output from a PWM controller. The primary objective of this system is to develop a solution that can identify PV modules operating under suboptimal conditions, which can be caused by various factors such as increased solar cell temperature, cloud cover effects, PV module degradation, and the performance of the Pulse-Width Modulation (PWM) solar charge controller (SCC). This is crucial because PV modules can be susceptible to various environmental and technical factors that may impact their efficiency and power output. By closely monitoring the performance of each PV module using the ACS712-based current sensing system, the researchers aim to promptly detect and address any issues that may arise, ensuring the overall optimal operation of the PV system.

Pancasila, as Indonesia’s foundational ideology, plays a central role in shaping the country’s legal framework. However, its application in contemporary legal reform presents significant challenges amidst evolving societal dynamics and international legal debates. This study critically evaluates the incorporation of Pancasila within Indonesia’s legal reform processes, emphasizing its relevance in addressing domestic and global tensions. The urgency of this research stems from growing critiques of Indonesia’s legal alignment with international standards while preserving its ideological roots. Concurrently, the rise of globalization and pluralism demands an adaptive yet principled approach to Pancasila’s integration into modern legal structures. This research provides a novel perspective by analyzing specific legal cases and policy reforms where Pancasila principles have been contested or reinterpreted. Through a doctrinal and socio-legal analysis, the study examines the compatibility of Pancasila with contemporary global legal norms, including human rights, environmental law, and economic governance. Furthermore, it explores Indonesia’s engagement in international debates on the role of ideology in law, offering insights into the challenges of balancing national identity with global expectations. The findings reveal that while Pancasila remains a unifying framework, its inconsistent application risks undermining its potential to guide inclusive and sustainable legal reforms. This study contributes to the broader discourse by proposing actionable recommendations for harmonizing Pancasila with international legal developments while safeguarding Indonesia’s ideological integrity. It serves as a critical resource for scholars, policymakers, and practitioners navigating the intersection of ideology, law, and globalization.

Background: Combat sports are competitive contact sports where two participants (one-on-one conflicts) battle. Rapid weight loss (RWL) with dehydration (a dangerous practice) followed by rapid weight gain (RWG) is a standard pre-competition protocol. To achieve pre-competition weight limits, combat athletes often use rapid weight loss techniques that, in addition to an unhealthy diet, play an essential role in their physical performance. Objective: This pilot study assessed the impact of these two factors on the perceived performance of combat athletes, such as speed, endurance, fitness, and more, in two Lebanese cities. Methods: We selected a group of 384 combat athletes aged 18-40 from 65 private clubs in Beirut and Mount Lebanon. All completed questionnaires about socio-demographics, BMI, rapid weight loss practices, diet, and perceived performance. Findings: Combat athletes who adopted adequate rapid weight loss practices were positively associated with a healthy diet (polycorrelation = 0.1894, SE = 0.0745, Wald chi-square statistic = 6.46320, p<0.0001). Also, adequate rapid weight loss (polycorrelation = 0.9667, SE = 0.0083, Wald's chi-squared statistics = 13565.23, p<0.0001) and healthy diet (polycorrelation = 0.3393, SE = 0.0700, Wald's chi-square statistics = 23.4948, p<0.0001) were positively associated with compatible perceived performance. Recommendation: There is a link between rapid weight loss practices, poor eating habits, and perceived performance. Rapid weight loss practices can prevent combat athletes from getting the nutrients they need, which can interfere with their performance, damage their immune system, and increase the risk of injury. Large-scale longitudinal studies are required to confirm the findings.

After the COVID-19 pandemic, global focus on health has increased, including mental health issues. However, many people in Indonesia still consider mental health to be a taboo subject. In reality, mental health has a significant impact on community life. Poor mental health, such as stress, anxiety, and depression, can negatively affect physical well-being and reduce the quality of life, particularly in large cities like Tangerang. Tangerang's numerous industrial factories contribute to air pollution, the lack of green spaces, and significant social pressures, all of which increase stress among its residents and can lead to mental health issues that may result in harmful actions toward themselves or others. In 2018, TangerangNews reported 15 suicide incidents in Tangerang City, Tangerang Regency, and South Tangerang, with causes ranging from economic factors to depression. According to Pasla (2023), several methods can prevent the negative impacts of mental health issues, including maintaining and improving mental well-being through actions that balance physical and spiritual conditions. In response to these challenges, the planning and design of a Wellness Center could be an inspiring solution with the potential to positively impact the community in Tangerang. Integrated with the Healing Environment approach, which creates a more healing and restorative building environment, this facility aims to enhance community wellness in a positive, targeted, and effective manner, reducing stress levels and preventing depression to improve the quality of life in Tangerang.

El Nino and La Nina events affect the conditions of the rainy season and dry season, especially as a cause of flooding in coastal areas. The North Coast of Java is a coastal area that is prone to disasters due to the influence of sea level anomalies caused by the interaction of the sea and the atmosphere. The northern coast of East Java, which is directly adjacent to the coast, has a high level of vulnerability to tidal flooding or rob disasters. This study aims to examine the effect of the Nino 3.4 index on the El Nino and La Nina phases in influencing rainfall on the northern coast of East Java, especially in the areas of Tuban, Lamongan, Gresik, Surabaya City, Sidoarjo, Pasuruan, Probolinggo, and Situbondo. The method used is a correlation analysis between rainfall parameters and the Nino3.4 index to determine the relationship between parameters. The results of the study on La Nina, El Nino, and Neutral conditions have a negative relationship in almost all research locations with moderate to very low correlation values. This study provides an explanation of the relationship between rainfall and ENSO to flooding events on the northern coast of East Java.
