Abstract

The increasing urgency of climate change mitigation and the global transition toward sustainable energy systems have accelerated interest in green hydrogen as a clean energy carrier. Green hydrogen produced through water electrolysis powered by solar energy offers a promising pathway to decarbonize industrial, transportation, and energy storage sectors. However, challenges related to energy conversion efficiency, production cost, and environmental sustainability remain major barriers to large-scale deployment. This study aims to analyze and optimize green hydrogen production from solar-powered water electrolysis by integrating technical, economic, and environmental perspectives. The research employs a qualitative literature review method, synthesizing peer-reviewed studies published between 2015 and 2025. Data were collected through a systematic review process following the PRISMA framework and analyzed using thematic content analysis. The findings indicate that technical optimization through high-efficiency photovoltaic systems, advanced electrocatalysts, and system integration can significantly improve solar-to-hydrogen efficiency. Economic analyses reveal that reductions in photovoltaic and electrolyzer costs, optimal system sizing, and strategic site selection are key to lowering the levelized cost of hydrogen. Environmentally, life cycle assessments demonstrate substantial greenhouse gas emission reductions compared to fossil-based hydrogen pathways. An integrative optimization approach is essential to ensure balanced performance, cost-effectiveness, and sustainability.

Abstract

The escalating buildup of petrochemical based plastic waste has intensified efforts to develop sustainable bioplastics derived from renewable materials. Accordingly, this research investigates how variations in carrageenan content influence the physical and mechanical characteristics of alginate carrageenan composite bioplastics formulated with glycerol as a plasticizer. Alginate was extracted from Sargassum sp. and carrageenan from Kappaphycus alvarezii. Bioplastics were prepared using carrageenan concentrations ranging from 1.5 to 3.5 grams and characterized for tensile strength, elongation, thickness, water resistance, biodegradability, and opacity. The results indicate that carrageenan concentration significantly affects tensile strength, elongation, thickness, biodegradability, and opacity, while water resistance is not significantly influenced. The optimal formulation was obtained at a carrageenan concentration of 1.5 grams, complying with Japanese Industrial Standard and SNI 7188.7:2016. Further studies are recommended to incorporate additional materials to improve water resistance and functional performance of the bioplastics.

Abstract

The petrochemical industry plays an important role in the supply chain of polymer-based products. In terms of raw materials, this industry still relies heavily on fossil-based feedstocks whose availability is gradually declining. On the other hand, the products generated from this industry contribute to the increasing accumulation of plastic waste due to their resistance to natural degradation. Nevertheless, the demand for industrial sustainability continues to rise along with the increasing needs of society. The development of bioplastics can serve as one of the diversification strategies to produce value-added materials, specifically in biodegradability. This study aims to produce bioplastics using various type of starch and fillers with propylene glycol as a plasticizer and to analyze their characteristics. The results of this study indicate that the appropriate combination of starch, filler, and plasticizer can enhance the physical characteristics of bioplastics. The bioplastics produced using various combinations of starch types and fillers in this study were able to degrade, which is better than standard commercial bioplastics that had not degraded within seven days. However, further optimization of the formulation is still required to achieve physical characteristics that approach or meet the Indonesian National Standard (SNI).

Abstract

Ammonia contamination in water poses serious ecological risks, while commercial bioremediation agents remain costly for widespread application. This study evaluated the technical and economic performance of a self-formulated biological agent made from golden apple snail shells and banana pseudostems for ammonia removal. A laboratory-scale preliminary experiment used 500 mL batch reactors containing synthetic wastewater in a 2 × 3 × 3 factorial design without replication, comparing EM4 and the self-formulated agent at initial ammonia concentrations of 10, 30, and 50 ppm over 1, 2, and 3 days. Ammonia was measured by the Nessler spectrophotometric method and analyzed using ANOVA GLM. The self-formulated agent showed performance comparable to EM4, with both achieving more than 80% removal under suitable conditions. Removal efficiency was influenced by the interaction between ammonia load and contact time, while cost analysis indicated a potential 92.1% saving. Further replicated pilot-scale studies with abiotic controls and real wastewater are recommended.
