This study delves into the philosophical and theological core of the concept of ownership in Islamic economics, a paradigm fundamentally distinct from capitalism and socialism. We uncover the essence of ownership as a divine trust, categorized into individual, public, and state domains. Our findings demonstrate how each type of ownership is governed by clear boundaries and rights, tightly integrated with social responsibility to achieve universal well-being and distributive justice. This study also examines the dynamic harmonization between private and public ownership, achieved through vital instruments like zakat, infaq, sadaqah, and productive waqf, as well as the crucial role of government in providing public goods. Despite facing significant challenges such as the dominance of the global capitalist economy and low sharia literacy, we highlight digitalization as a strategic opportunity to boost the efficiency, transparency, and inclusion of sharia finance. This opportunity holds substantial potential to strengthen the harmonization of ownership within the broader Islamic economic ecosystem. In short, a deep understanding of this Islamic concept of ownership is key to formulating more just and balanced economic policies and community development in today's rapidly evolving modern era.

It is recommended that coffee shop MSME operators focus on long-term promotional strategies to build customer loyalty and increase income.

Cyber crime is increasingly prevalent with various modes, one of which is fraud under the guise of lottery prizes. This crime not only causes financial losses but also complicates law enforcement officials in terms of jurisdiction, especially if the perpetrators and victims are located in different regions, even across countries. This research aims to analyze how jurisdiction is enforced in dealing with cyber-based fraud crimes and examine the effectiveness of national legal instruments against the digital fraud mode. The research method used is a normative juridical approach with secondary data analyzed descriptively-analytically. The results show that jurisdictional enforcement in this case still faces technical and legal challenges, especially in the aspect of inter-state coordination and the limitations of domestic legal instruments in reaching cross-border perpetrators. Strengthening international cooperation and updating national regulations are needed to anticipate the dynamics of cybercrime.

This study uses a qualitative method to examine legal protection for female workers who experience discrimination in employment relationships. Discrimination against women in the workplace remains prevalent, taking forms such as unequal pay, limited opportunities for promotion, and sexual harassment, all of which affect their safety and comfort at work. Legal protection for female workers is regulated by various laws, including the Manpower Act, the Human Rights Act, and ILO conventions ratified by Indonesia. However, the implementation of these protections is often ineffective due to weak law enforcement, limited awareness among female workers regarding their rights, and the persistence of patriarchal culture. This study aims to analyze the extent to which legal regulations and their implementation function effectively, as well as the obstacles female workers face in claiming their rights. Data were collected through in-depth interviews, literature review, and document analysis. The findings indicate the need to strengthen labor inspection institutions and provide legal education for female workers to achieve justice in employment relationships.  

A landslide that occurred on May 24, 2024, in Pekon Datarajan, Ulubelu District, Tanggamus, Lampung, caused significant disruption to provincial road access and resulted in material losses. This study aims to assess the post-failure slope stability through field geotechnical investigation and numerical analysis using the Limit Equilibrium Method (LEM), and to propose immediate countermeasures. The slope materials consist of MH (inorganic silt) and ML (elastic silt) with high moisture content and moderate to high swelling potential. The lithology is dominated by montmorillonite clay, which has hygroscopic characteristics, making it highly vulnerable to water infiltration that reduces shear strength and increases the risk of slope failure. Stability analysis indicates a post-failure factor of safety (FoS) of 1.36 (static loading) and 1.03 (dynamic loading), which decreases to 1.07 beneath raised groundwater conditions. Recommended immediate mitigation includes surface runoff control, the construction of impermeable drainage systems, the sealing of cracks using impermeable materials, and the installation of temporary slope reinforcements such as sheet piles. The implementation of these measures increased the FoS to 1.61 (static loading) and 1.16 (dynamic loading). This study provides a technical basis for the rapid and effective mitigation of landslides in areas with similar geological and hydrological conditions.

In many wireless sensor network (WSN) applications, nodes are randomly deployed and self-organize into a wireless network to perform tasks. In practice, recharging the batteries of network nodes after deployment is often difficult. Network nodes often operate autonomously, so the main focus is on increasing the node lifetime. Data redundancy is another limitation that makes nodes inefficient. In most cases, densely deployed nodes in a monitoring area will have redundant data from neighboring nodes. Therefore, we propose a clustering technique to select the Cluster Head (CH) node in small-scale WSNs. Since transmission consumes more energy than data collection, this protocol enables reactive routing, where transmission occurs only when a certain threshold is reached. In addition, based on their heterogeneous energy levels, nodes can be grouped into three categories: Normal, Intermediate, and Advanced. Simulation results in MATLAB/Simulink show that, after approximately 3000 rounds, the proposed method successfully transmitted about 3.1 × 104 packets to the base station, compared to 2.3 × 104 packets for the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. In addition, the time when the last node died was approximately 3,500 rounds, whereas the LEACH protocol only maintained about 1,500 rounds. The results have shown the effectiveness of this technique in reducing the dead node rate and increasing packet transmission efficiency.

Cancer is a malignant disease caused by the abnormal growth of cells in body tissues, making it one of the leading causes of death worldwide. The high prevalence of cancer has driven the search for new, effective, and safe anti-cancer agents, one of which involves utilizing phytochemical compounds from plants such as Java plum (Syzygium cumini), which has attracted attention as a potential anti-cancer agent due to its therapeutic potential and low toxicity. This literature review examines recent studies on the anti-cancer activity of Java plum across various cancer types through in vitro studies. The results show that Java plum exhibits several key mechanisms in inhibiting cancer cell growth, including induction of apoptosis, cell cycle arrest, inhibition of cell proliferation, ROS production, targeting of cancer stem cells, anti-inflammatory effects, modulation of epigenetic changes, and antioxidant protection.
