Photovoltaic (PV) systems are a promising renewable energy source due to their ease of installation, eco-friendliness, and abundant solar radiation availability. Indonesia has a theoretical potential of 4.625 kWh/m² and a practical potential of 3.767 kWh/kWp; however, as of September 2021, its installed capacity was only 194 MW. Land constraints have led to the development of floating PV systems, which reduce land usage and enhance module efficiency due to lower temperatures above water. Nonetheless, PV systems face challenges from solar radiation intermittency, influenced by cloud opacity, causing output power fluctuations. This study maps cloud opacity patterns on Kodingareng Island based on dry and rainy seasons using 2020 BMKG data. Results indicate that output power during the dry season is more stable than in the rainy season due to lower cloud cover. Conversely, thick cloud cover during the rainy season reduces solar radiation reaching PV modules, resulting in fluctuating power output. Thus, floating PV systems demonstrate better energy availability during the dry season. This study highlights the importance of understanding cloud opacity patterns in planning floating PV systems to address the challenges of solar radiation intermittency.

Eco-pharmaceuticals are an emerging solution in the pharmaceutical industry, aimed at reducing environmental impacts through sustainable production, distribution, and disposal practices. The growing concern over pharmaceutical waste, especially in low-resource settings, highlights the need for greener alternatives. Pharmaceutical residues, often not fully removed during conventional wastewater treatments, contribute significantly to water pollution and disrupt aquatic ecosystems. Eco-pharmaceuticals address these issues by using biodegradable materials, environmentally friendly production methods, and safer disposal techniques, thereby reducing the persistence of pharmaceutical contaminants in the environment. Life-Cycle Assessment (LCA) is an essential methodology used to evaluate the environmental impact of pharmaceutical products, considering all stages from raw material extraction to end-of-life disposal. The results of LCA show that eco-pharmaceuticals significantly reduce water pollution potential and carbon emissions when compared to conventional drugs. Additionally, they offer a more resource-efficient alternative by minimizing waste generation during production and ensuring safer end-of-life disposal. Despite the clear environmental benefits, challenges remain in transitioning to eco-pharmaceuticals, particularly in low-resource settings where infrastructure for waste management is limited. Cost and availability of eco-pharmaceuticals may also pose barriers to widespread adoption. However, with appropriate policy interventions, public education, and technological innovations, these challenges can be addressed. This study underscores the potential of eco-pharmaceuticals in mitigating environmental degradation while offering a sustainable and cost-effective alternative to traditional pharmaceuticals, particularly in regions most vulnerable to pollution.

Drought is a hydrometeorological disaster that significantly affects water availability and agricultural activities. Pesisir Selatan Regency has diverse topographic conditions that influence the level of vulnerability to drought, thereby requiring a comprehensive spatial analysis. This study aims to map drought risk by integrating slope steepness with other biophysical parameters using Geographic Information Systems (GIS). The data employed include slope maps derived from DEMNAS, rainfall data (CHIRPS 2024), soil types, land use, and river networks. The analysis was conducted through scoring and overlay methods to produce a drought risk map. The results indicate that areas with very steep slopes (>45%) have a high level of vulnerability due to surface runoff dominance and low infiltration capacity, particularly in Bayang Utara District. In contrast, flat to gently sloping areas dominated by rice fields and forest cover are relatively low-risk. Overall, drought risk in the region is classified into three categories: low, medium, and high. The resulting maps can serve as a basis for local governments in developing spatial planning policies, water conservation infrastructure, and disaster mitigation strategies that are more adaptive and sustainable.
