This research investigates the potential of integrating waste heat recovery and geothermal exchange within district heating systems as a carbon-neutral energy solution tailored to tropical urban settings. Tropical climates present unique challenges for heating, ventilation, and air conditioning (HVAC) systems, including high humidity, temperature fluctuations, and increasing energy demands, particularly for cooling. This study aims to address these challenges by proposing a hybrid district heating system that combines renewable energy sources to improve energy efficiency and reduce carbon emissions. The methodology includes thermal and hydraulic modeling, performance simulation of the hybrid system under tropical climate conditions, and emission and energy efficiency analysis. The results indicate that the hybrid system significantly reduces energy consumption and carbon emissions compared to traditional heating systems, with waste heat recovery optimizing energy use and geothermal exchange enhancing system efficiency. The comparison with conventional systems and other environmentally friendly alternatives reveals that the hybrid system offers a cost-effective, sustainable solution for tropical urban areas. The study concludes that integrating waste heat recovery and geothermal exchange is feasible and can contribute to the creation of carbon-neutral cities. Future research should focus on optimizing geothermal systems in tropical climates and exploring further integration with other renewable energy sources to enhance system performance and sustainability.

This study examines the ethics of social media use from the perspective of hadith and verses of the Qur'an with a focus on privacy and social responsibility. Social media, as a dominant communication tool, is often misused, resulting in privacy violations, the spread of inaccurate information, and other negative impacts. This study uses a literature approach to authentic hadiths and interpretations of verses of the Qur'an. The results of the study show that Islam prohibits the actions of tajasuss (spying) and ghibah (backbiting), as emphasized in the hadith: "Whoever spies on others, Allah will spy on him." In addition, QS. Al-Isra: 36 reminds us of the importance of verifying information before it is disseminated. The principle of amar ma'ruf nahi munkar requires social media users to encourage goodness, share positive content, and avoid destructive behavior, such as bullying or the spread of inappropriate content. The application of Islamic ethics in social media can reduce the negative impacts of technology while creating safer and more beneficial interactions in cyberspace.

This finding indicates a delay in the market response to public information related to the boycott call, which is characteristic of markets with lower efficiency levels. This research is expected to provide insights for the public and investors regarding the dynamics of the capital market in Indonesia in responding to a social event. In addition, the results of this study can also be taken into consideration for market authorities and related institutions in evaluating policies aimed at improving capital market efficiency in Indonesia.

Augmented Reality (AR) applications are rapidly gaining popularity across various industries, including education and marketing. By integrating real-world environments with virtual objects, AR enhances user understanding and information display for products. This paper explores Diminished Reality (DR) techniques, which are used to visually remove real objects from AR environments. Despite growing interest, much of the DR research predominantly focuses on maintaining consistency between real and virtual elements, particularly in texture handling on marker areas. Our study addresses the preservation of depth consistency using edge detection and planar segmentation to construct a depth map, essential for developing effective DR methods. We introduce a two-stage process involving depth mask construction, each stage equipped with error measurement for iterative refinement. Our proposed techniques, Planarity and Boundary Depth, are evaluated on a dataset of high-quality RGB images captured by digital cameras. Experimental results validate the effectiveness of our methods across various performance metrics, confirming the practicality of our approach in enhancing AR experiences.

The issue of land ownership disputes is a complex issue and often triggers prolonged conflicts in Indonesia. Land disputes can be caused by various factors, such as overlapping certificates, illegal land control, and weak law enforcement. In this context, legal politics becomes an important instrument in formulating policies to resolve land disputes fairly and efficiently. This paper aims to analyze the role of legal politics in resolving land ownership disputes, identify obstacles in policy implementation, and offer solutions to increase the effectiveness of dispute resolution. The research uses a normative approach with analysis of statutory regulations, official documents and academic literature. The research results show that existing regulations, such as the Basic Agrarian Law no. 5 of 1960, requires harmonization with other policies to overcome overlapping regulations. In addition, the role of mediation and arbitration institutions is considered crucial in reducing the burden on courts. However, weak legal dissemination to the community is a significant obstacle in policy implementation. This paper recommends strengthening regulations, increasing the capacity of mediation institutions, and legal education to the community as strategic steps to create a more effective land dispute resolution system.
