Abstract

World seaweed production in 2020 published by the Food and Agriculture Organization of the United Nations (FAO), Indonesia was ranked second as the largest seaweed producer with production of 11.8 million tons. The aim of this research is: To analyze the characteristics of seaweed liquid waste at PT. XYZ. To design a seaweed liquid waste processing process at PT. XYZ based on physics-chemistry as recycled water. Methods include analysis and experiments. This method is used to analyze the characteristics of liquid waste and determine the design of the seaweed liquid waste processing process at PT. XYZ. Research results: The characteristics of the seaweed liquid waste produced do not meet the quality standards in Kep.08/Men. LH/2009 concerning Industrial Waste. A physic-chemical based liquid waste processing process with neutralization, filtering and aeration can be used as recycled water in the alkali treatment process.

Abstract

ISO 14001:2015 is an international standard issued by the International Organization for Standardization that regulates Environmental Management Systems (EMS) to help companies manage environmental impacts, comply with regulations, and achieve continuous improvement. Manufacture Industry, a foreign investment company engaged in diesel engine production, implements EMS as part of its commitment to environmental sustainability. This study evaluates the implementation of ISO 14001:2015 by comparing each clause of the standard with actual operational practices within the company. Data were collected through field observations and document reviews. The results show that Manufacture Industry has effectively implemented all clauses of ISO 14001:2015, particularly in waste management, air quality monitoring, and regulatory compliance. However, improvements are still needed in increasing employee awareness regarding the use of PPE in high-risk work areas. This study provides a more practical and structured approach to EMS evaluation by integrating clause-based ISO assessment with real industrial practices, which can serve as a reference for industries in improving EMS performance and operational control.

Abstract

This article critiques the effectiveness of the Sentra Kreasi Atensi (SKA) Program innovation, which shifts the paradigm of homelessness management from a repressive-charitable approach to empowering entrepreneurs through collaborative governance. Although conceptually progressive, the SKA carries the risk of systemic failure due to the dominance of centralized mega-infrastructure development, which is costly but low in scalability. This research uses a qualitative descriptive-analytical method based on secondary data, which is dissected through the Public Logic Framework instrument, Collaborative Governance theory, and the Innovation Policy framework. The analysis results show that SKA innovation has fundamental structural weaknesses: (1) reliance on a reactive emergency paradigm in the downstream sector; (2) absolute dependence on the state budget; (3) spatial inefficiency that triggers new social exclusion; and (4) bias towards manual vocational training that ignores integrated care and digital literacy. As an alternative policy, the government is recommended to transition from merely "patching the system" to structural transformation through the implementation of preventive safety nets in the upstream sector, Social Investment financing schemes, decentralization of micro-housing (tiny house villages), implementation of the Integrated Care Model, and adoption of blockchain-based transactional identity. Through this reorientation, state innovation can evolve into a sustainable ecosystem of self-reliance for marginalized groups.
