Abstract

Used cooking oil, which is often thrown away after use, can have a negative impact on the environment if not managed properly. Through a community service program implemented in Sidomoyo Village, Godean, Sleman, efforts were made to convert used cooking oil into biodiesel as an environmentally friendly alternative fuel for household stoves. This program aims to empower the community by providing knowledge and skills in processing used cooking oil, so that this waste can be reused productively and reduce environmental pollution. The process of converting used cooking oil into biodiesel involves a simple method that can be implemented by village communities at an affordable cost. The use of biodiesel in household stoves is expected to be an alternative energy solution that is economical and environmentally friendly, as well as supporting efforts to reduce domestic waste. The results of this activity show the enthusiasm of the community in adopting this technology, as well as increasing awareness of the importance of managing used cooking oil waste. It is hoped that this program can become a model of curiosity that is implemented in other villages.

Abstract

This article examines the quality of GoTo Group's sustainability disclosure and its managerial implications for platform firms. The research uses a qualitative document-based case study drawing on GoTo Group's Sustainability Reports for FY2022, FY2023, and FY2024, all of which were audited or externally verified, including verification by the Science-Based Targets Initiative for the FY2023 report. The analysis is structured around three indicators: measurability, verifiability, and information depth across environmental, social, and governance dimensions. The findings show that GoTo has developed a strong sustainability narrative, but the quality of its disclosure remains uneven. Environmental disclosure still relies heavily on relative metrics without sufficient absolute baselines. The carbon offset initiative (GoGreener) is not fully supported by clear information on fund allocation and independent verification. Social disclosure emphasizes inclusion and partner support, yet provides limited evidence on structural impacts on income stability and risk distribution. Governance disclosure also remains constrained by limited transparency regarding algorithmic mechanisms that are material to platform accountability. These findings suggest that sustainability disclosure in platform firms should be assessed not only by the strength of narrative communication, but also by the quality of indicators, the traceability of evidence, and the clarity of governance arrangements. The article's conceptual contribution lies in showing that sustainability legitimacy in platform firms depends on measurability, verifiability, and information depth as the basis for evaluating disclosure credibility.
