Abstract

This research aims to analyze the effectiveness of legal protection for local business actors in government procurement of goods and services following the implementation of Presidential Regulation No. 12 of 2021. The research method employs a normative juridical approach with descriptive-analytical qualitative analysis techniques on procurement regulations and their implementation. Data collection techniques were conducted through comprehensive literature studies on primary, secondary, and tertiary legal materials relevant to legal protection for local business actors. Research findings indicate a paradigm transformation from passive to active-affirmative approaches through layered protection mechanisms including price preferences up to 15% for domestic products, administrative procedure simplification, digital information access facilitation, and strengthened risk-based supervision systems. Implementation of this regulation successfully increased local business participation with a 35% increase in contract value and creation of 150,000 new jobs within two years of implementation. However, challenges remain in inter-agency coordination with implementation variance reaching 40%, limited human resource capacity, and suboptimal integration of supervision information systems. The research concludes the necessity for optimization strategies through strengthened real-time monitoring, integrated digital platform development, and systematic capacity building programs to ensure sustainable legal protection effectiveness

Abstract

Household waste management has become a serious issue in coastal areas, particularly in stilt-house settlements that lack a structured waste management system. RT 36 Gang Rakyat, located in Klandasan Ilir Subdistrict, Balikpapan Kota District, was chosen as the activity site because the community still tends to burn or dispose of waste indiscriminately and has a low level of awareness regarding waste separation. This community service activity aimed to increase residents’ awareness and skills in waste management. The implementation methods included field surveys, community clean-up and awareness campaigns, demonstrations of compost-making from organic waste, creative recycling training for inorganic waste, and evaluation of the results. The outcomes showed that residents became interested in sorting and processing waste. They successfully produced compost used for medicinal and vegetable plants around their homes and created simple products from inorganic waste, such as tissue holders. This community service activity transformed residents’ perceptions of waste from useless material into a valuable resource. The model has the potential to serve as a sustainable waste management approach that can be replicated in other coastal communities.
