The rapid growth of Solar Power Plant (PLTS) installations in Indonesia faces efficiency challenges due to the continuously changing position of the sun. Fixed panel systems cannot absorb solar radiation optimally throughout the day. This study aims to evaluate and compare the efficiency of various solar tracking system methods developed over the last five years using a simple literature review approach. The research method was conducted by collecting, screening, and synthesizing secondary data from five reputable scientific journals using a synthesis matrix. The review results indicate that single-axis tracking systems increase power efficiency by 15% to 24.5%. Meanwhile, dual-axis systems achieve higher efficiency, ranging from 30% to 35%, by tracking both horizontal and vertical solar movements. In terms of control systems, astronomical algorithms are found to be more reliable in cloudy weather conditions than pure light sensors. However, the internal power consumption of the actuator motors remains a critical factor that can reduce the system's net energy gain. The implication of this study emphasizes the importance of shifting future research focus toward energy-saving algorithm optimization to maximize net power yield in dynamic solar panel implementations.

Open burning of household waste remains the dominant waste disposal practice in rural areas of Indonesia, posing significant risks to public health and environmental quality. This community service activity aimed to provide an innovative, low-smoke waste combustion solution — the rocket stove incinerator — to the residents of Dusun Allukeke, Desa Belapunranga, Kecamatan Parangloe, Kabupaten Gowa. A baseline survey conducted during PBL 1 revealed that 87.6% of households disposed of waste through open burning. An asset-based community development (ABCD) approach was adopted, engaging community members at every stage from planning, construction, to utilisation. The rocket stove was constructed over three days using locally available materials and was demonstrated to significantly reduce visible smoke emissions compared to conventional open burning. The technology works through a vertically insulated combustion chamber that promotes near-complete combustion, reducing waste volume by 50–90% while suppressing particulate matter and hydrocarbon emissions. Community participation strengthened local ownership of the solution. This activity demonstrates that appropriate technology co-constructed with communities can serve as a practical, sustainable, and replicable model for rural waste management.
