Consumer dispute resolution in Indonesia is an increasingly relevant issue, considering the high dynamics of transactions that occur in the goods and services sector, including in the property sector. Consumers, as the weaker party in business transactions, often face problems related to the quality of goods/services received, delays, unilateral cancellations, or even failure in property development. Therefore, resolving consumer disputes is very important and requires adequate legal protection. This type of research is normative juridical research. Normative research is literature research by examining theoretical approaches and concepts that examine consumer disputes. Normative juridical research is legal research that places law as a building system of norms. Problems arise when consumers in good faith have paid all Down Payment obligations, but the business actor actually takes a unilateral decision to cancel the apartment construction project. Consumers who have invested funds amounting to IDR 307,530,900 are trying to get a refund, but the business actor does not show responsiveness and good faith in the refund process. This situation finally forced consumers to take legal action by filing a lawsuit with BPSK Medan City on December 5 2022. This case is a clear example of the application of consumer protection and the importance of BPSK as an alternative for resolving disputes outside of court. This decision also reflects the principles of justice and legal certainty in consumer disputes, where agreed consumers can obtain their rights through an arbitration mechanism.

That housing and settlement development by private business entities is compatible with the Sustainable Development Goals (SDGs) or can also be called Sustainable Development Goals (SDGs) is a sustainable development agenda initiated and agreed upon by the United Nations. Meanwhile, the construction of houses by individuals or individuals is very inconsistent with the programs or agendas set forth by the national and world governments. Of course, if we examine further, the development carried out by each person is very contrary to "participating in implementing world order" as described in the preamble to the 1945 Constitution of the Republic of Indonesia. The legal issue of this normative legal research: What is the government's authority in the implementation of housing development? How is the legal protection for people or entities that organize housing development in Law Number 1 of 2011 concerning Housing and Residential Areas? The government's authority in the implementation of housing development includes policy regulation, implementation supervision, housing provision facilitation, inter- government coordination, community empowerment, and education. Through this authority, the government seeks to create a decent and sustainable residential environment for all levels of society. Legal protection for persons or entities that organize housing development is comprehensively regulated in Law No. 1 of 2011 concerning Housing and Residential Areas. Legal protection includes: 1. Community Rights. 2. Developer's Obligations. 3. Sanctions for Violations. 4. The Role of the Government.

This study examines the construction of narratives on immoral issues in political discourse through a critical approach.

Indonesia, as an archipelagic country with over 17,000 islands, faces significant challenges in providing electricity access, particularly to small and remote islands. One promising solution is Solar Power Plants (PLTS), both land-based and floating solar plants that utilize water surfaces, suitable for areas with limited land availability. This study evaluates the economic feasibility of floating solar plants and land-based solar plants using the Levelized Cost of Electricity (LCoE) approach. LCoE encompasses all costs of construction, operation, maintenance, and energy production over the plant's lifespan, serving as a key benchmark in selecting power generation technologies. The findings show that the LCoE for floating solar plants is Rp11,197.00/kWh, lower than land-based solar plants at Rp11,769.00/kWh, although both exceed the electricity purchase price in Kodingareng, South Sulawesi, at Rp2,460.00/kWh. This difference is influenced by higher construction costs for floating solar plants but offset by greater energy output and lower operation and maintenance costs. This research provides a basis for developing solar power systems in archipelagic regions, emphasizing efficiency and sustainable energy solutions.
