This study presents a comprehensive bibliometric review of the scholarly literature on renewable energy financing and its link to sustainable development. Utilizing data from the Scopus database and analyzed through VOSviewer, the study maps thematic clusters, keyword co-occurrences, author collaborations, and country-level partnerships from 2000 to 2024. The findings reveal that "sustainable development" serves as the conceptual core of this research domain, closely associated with terms such as "green finance," "energy efficiency," and "climate change." Recent trends indicate a growing scholarly focus on financial instruments like green bonds and the broader policy landscape of energy transition. Co-authorship and country collaboration networks demonstrate strong regional concentrations, with China, the United States, and India emerging as key contributors. While the literature is rich in financial and technological insights, gaps remain in addressing social equity, regional financing models, and the integration of digital finance. This study contributes to the literature by offering a systematic overview of research developments, identifying influential contributors, and suggesting future directions for interdisciplinary inquiry into sustainable energy finance.

Utilizing technologies for processing fruits and vegetables is crucial for tackling major issues with contemporary food systems. In the supply chain for fruits and vegetables, this research examines the diverse effects of processing methods on sustainability, waste reduction, and nutritional improvement. Our study employs a mixed-methods approach that combines qualitative information from expert interviews with quantitative data analysis from 150 samples to provide a thorough evaluation of this topic. The results show that processing technologies have a considerable impact on waste reduction, energy conservation, and resource efficiency. These technologies are also crucial for extending product shelf life and raising marketable yield, which decreases food waste. Although some nutrients are lost during processing, cutting-edge methods have been shown to increase nutrient retention. This study not only clarifies the intricate relationships that exist between processing technologies and sustainability, but it also offers a foundation for future research in this vital area. The lessons learned from this study have significant significance for the creation of sustainable and nutrient-dense food systems as we struggle with the urgent challenge of feeding a growing global population while protecting the environment and enhancing nutrition.

This research investigates the impact of food packaging innovations on shelf life extension and food waste reduction within a leading Indonesian food company. Employing a quantitative approach, the study incorporates a diverse sample of products subjected to various packaging technologies. Descriptive and inferential statistics reveal a statistically significant increase in shelf life by 50% and a substantial reduction in food waste by 40%. Consumer surveys underscore positive perceptions, with 80% expressing a preference for sustainable packaging. Economically, a 15% reduction in costs associated with product losses supports the business case for innovative packaging. These findings contribute empirical evidence to the discourse on sustainable food systems, emphasizing the practical effectiveness and economic viability of advanced packaging technologies.

The circular economy approach has begun to be applied as a model for waste management in Indonesia. This approach is expected to improve environmental quality and increase economic value. The Anyelir Medan waste bank has implemented the application of circular economics in waste management with the concept of saving waste to gold. This study aims to analyze the operational activities of the carnation waste bank in realizing the circular economic model of waste management. The research method is descriptive research with observational research design. Data is processed using mass balance analysis. Through the Anyelir waste bank, savings can be collected into gold savings under the guidance of PT Pegadaian Persero. Waste managed at the Anyelir waste bank is 1640.94 kg per month with an average of 828.42 kg (50.48%) of plastic waste, 704.58 kg of paper (42.94%) and 107.92 metals (6.58%) . The results of the mass balance analysis show that the total reduction efficiency is 97.2% of the total waste that goes into bank waste. As much as 1450.97 kg (88.42%) of the waste was sold to recycling factories, 41 kg (2.5%) were used as recycled crafts and 103 kg (6.28%) were stored in stock. The rest goes to TPA as much as 45.95 kg (2.8%). The Anyelir waste bank does not only focus on economic value, but also tries to increase awareness of the environment, through education to improve the social life of the community and strengthen the economic pillars. The circular economy movement carried out by the Anyelir waste bank has produced processed waste into compost, recycled creations and raw materials for paper and plastic factories.

The increasing amount of organic waste requires special attention in its management. Efforts to conserve and manage organic waste in bioenergy are one of the current intensive efforts through the cultivation of BSF maggots. This study aims to see the effect of variations in waste composition on body weight growth in maggot growth, analyze fat, protein, and water content based on variations in waste composition decomposed by maggot, and determine the Waste Reduction Index (WRI). This research is a quasi-experiment with the pre-and-post Group Design method, using 5 variations of a waste composition consisting of catering waste, vegetable and fruit waste with washing or chopping treatment. The growth of magot larvae body weight was best in the variation of catering waste with slurry treatment, with the final weight of magot reaching 3025 grams from the initial weight of larvae weighing 50 grams. Proximate analysis was carried out on a maggot that was 21 days old, namely water content ranging from 60.73% to 65.42%, and fat content from 47.29% - 51.24%. The protein content is 19.11% - 42.76%. The results of one-way Anova analysis obtained Sig value. (0.000) < α then H0 is rejected, it can be concluded that the five variations of waste composition in maggot feed have a different average weight gain of maggot, and have different weight gain. The WRI value obtained is 2.4 - 2.99.
