The urgency of consumer protection in Sharia-compliant transactions has become increasingly prominent alongside the growth of the halal industry and rising public awareness of transactional justice based on Islamic principles. This study aims to formulate the theoretical and normative construction of consumer protection within the framework of Islamic law and to assess its compatibility with Indonesia’s positive legal system. Employing a normative juridical approach combined with a descriptive-analytical method, this research explores primary legal sources including Qur’anic verses, the hadiths of Prophet Muhammad (PBUH), and scholarly opinions found in classical and contemporary fiqh al-mu‘āmalāt literature, as well as secondary legal sources such as Law Number 8 of 1999 on Consumer Protection, fatwas of the National Sharia Council (DSN-MUI), and relevant academic literature. The analysis is conducted through content analysis to extract the values of justice, transparency, and balance of rights and obligations within contractual mechanisms. This study finds that core principles such as truthfulness (ṣidq), disclosure (bayān), and justice (‘adālah) constitute the essential foundation of consumer protection in the Islamic legal perspective. The prohibition of gharar (uncertainty), riba (usury), and tadlīs (fraudulent misrepresentation) is not merely a moral injunction but an integral safeguard mechanism for consumer rights. Furthermore, the institutional presence of supervisory bodies such as DSN-MUI and Sharia certification mechanisms has proven to be strategic, though they continue to face challenges in implementation, socialization, and consumer literacy. The findings also indicate a substantial opportunity for harmonizing Islamic legal principles with the national legal system within the framework of maqāṣid al-sharī‘ah. Therefore, this study recommends strengthening sectoral regulations based on Sharia principles, integrating fatwas into positive legal norms, and enhancing educational capacity for both business actors and consumers in order to realize ethical, equitable, and sustainable transactions.

This study explores the paradox of democracy in Muslim-majority societies, particularly how democratic political systems influence the role of religion and the construction of religious identity. Employing a qualitative-descriptive approach through literature review and case studies in Indonesia and Turkey, this article finds that democracy opens participatory space for religious expression while simultaneously enabling the domination of majoritarian Islamic identity in the public sphere. This transformation leads to the fragmentation and commodification of religious identity, shifting it from a spiritual-transcendent value toward a symbolic-political function. In Indonesia, post-Reformasi democracy has fostered the expansion of conservative Islamic movements via electoral and social mobilization. In Turkey, democratization under the AKP regime has turned into religious populism that undermines secularism. The study concludes that democracy in Muslim-majority societies holds a paradoxical potential: it can serve as a medium for religious reform or become a tool for identity-based hegemony. Hence, strengthening institutions, political ethics, and reflective religious narratives is essential to make democracy a just and inclusive arena.

Post-harvest handling of fish requires an effective cold chain system, including the availability of ice factories, to preserve the quality and freshness of catches. The presence of an ice factory enables fishermen to bring ice during fishing trips, ensuring the catch remains safe for consumption. The planning of a portable mini ice factory in Ciwaru Village, located within the Ciletuh National Geopark, aims to maintain fish quality along the southern coast of West Java. Although several ice factories exist in Sukabumi Regency, their availability at fish landing sites such as the Ciwaru Fish Auction Place (TPI) remains insufficient. According to the Regulation of the Minister of Marine Affairs and Fisheries No. 2 of 2021, assistance for ice factory construction is provided to fishermen groups following a feasibility study submission. This community service project aims to assist fishermen cooperatives in improving cold chain management and preparing a feasibility study for ice factory development. Key issues identified include limited human resource competence, hygiene and sanitation challenges, feasibility study preparation, and internal communication enhancement within cooperatives. Solutions are implemented through training programs, cold chain method applications, feasibility analysis for mini ice factories, and the development of an information system for fishermen. The planned ice factory unit has a capacity of 1 ton per 8-hour cycle, supported by three freshwater wells near the site. Economic analysis reveals an NPV of Rp1,170,676,141, an IRR of 10.91%, and a Net B/C Ratio of 1.64, with a BEP at 311 tons/year, well below the installed capacity of 788 tons/year, confirming its economic viability. The resulting feasibility study will serve as the basis for applying for government assistance, complemented by scientific publications, national media coverage, video documentation, and intellectual property registration.

Compensation is an effort to reduce the pollution load from other sectors to replace the wastewater load that will be discharged by businesses and/or activities due to river water quality being exceeded. Currently, most large rivers in Indonesia have exceeded the water quality standards set by the government. The one of the hospitals in Jember plans to discharge wastewater into the Bedadung River. However, the Biochemical Oxygen Demand (BOD) quality standard for the Bedadung River has been exceeded. Therefore, alternative compensation activities are needed to reduce the BOD levels of the Bedadung River. Bathing, Washing, and Toilet (MCK) facilities with biofilter septic tanks were chosen. This technology is considered to be able to effectively reduce the BOD concentration of domestic waste before being discharged into the environment. This study aims to calculate the potential for reducing the BOD pollutant load in Bedadung River water if compensation is carried out through the construction of MCK with a biofilter septic tank system, so that it is expected to provide a significant contribution to improving river water quality while supporting the sustainability of hospital activities.

In geotechnical engineering, building robust structures is crucial to ensure the bearing capacity of structures against external forces, so making sure soil strength and unreliable build cost and duration prediction are also very important and preliminary aspects of any construction project. Therefore, in this first-of-its-kind modern examine, the capability of various artificially intelligent (AI)-based models toward reliable forecasting and estimation of preliminary construction expenses, duration, and strength at shear is explored. First, background information about the revolutionary artificial intelligence (AI) technique along with its many distinct models ideal for geotechnical and building engineering problems is presented, The use of AI-based models in the literature for the aforementioned construction and maintenance applications is discussed in a number of current works, together with their benefits, drawbacks, and future directions.

The use of log wood as raw material for furniture and construction industry requires an optimal approach in the dimensions of management and production efficiency to increase economic value. This study aims to analyze the relationship between log wood dimensions (length, width, diameter) with the value of production results based on the percentage of efficiency (60%, 50%, 40%, and 30%). The data used are the results of observations of log wood dimensions from several types (unnamed and with codes: Piton, DL, UP, UD) along with the basic price value of the log. Calculations are carried out to determine the economic value of log wood based on the production efficiency scenario. The results of the study indicate that increasing production efficiency significantly affects the economic value obtained, with the UD log type providing the highest value at all levels of efficiency. This study provides recommendations for wood production optimization strategies based on comparisons of dimensions and efficiency as a basis for decision making in the wood resource-based industry.

The principle of proportionality plays an important role in ensuring the balance of rights and obligations between the parties in a reciprocal agreement. In the context of Indonesian contract law, this principle functions as a mechanism to prevent inequality that can harm one of the parties, especially in commercial and complex contracts. As stated by Hernoko (2016), the application of the principle of proportionality in commercial contracts aims to create substantive justice through a balanced exchange of rights and obligations between the parties. This study uses a normative legal approach with a literature study method, which involves an analysis of related laws and regulations and case studies. This approach allows researchers to explore the application of the principle of proportionality in various types of reciprocal agreements, including franchise agreements and construction service contracts. For example, a study by Susanto et al. (2021)1 highlights how the principle of proportionality is applied in construction service contracts to ensure a fair distribution of responsibilities between contractors and clients. The results of the analysis show that consistent application of the principle of proportionality can improve justice in contractual relationships. In franchise agreements, for example, Rahmawan et al. (2020)2 found that the application of this principle helps create a balance between the rights and obligations of franchisors and franchisees, who often have different bargaining positions. Thus, the principle of proportionality functions not only as a legal principle, but also as a practical tool to achieve justice in contractual practices.
