Physical modification of starch using microwave heat treatment (MHT) technology serves as an efficient and environmentally friendly alternative to enhance the functional properties of starch without chemical additives. This article aims to examine the influence of microwave power and heating duration on the swelling power and solubility of various starch types, including tapioca, taro, sago, and lotus rhizome. A review of four studies revealed that power and time parameters significantly affect the crystalline structure of starch granules, resulting in either enhancement or reduction of their functional properties. High power or prolonged heating may decrease swelling power due to crystal restructuring and granule disruption, while solubility increases as a result of amylose and amylopectin degradation. MHT has proven to accelerate the heating process in a volumetric and efficient manner, improving water absorption capacity and viscosity. Despite its drawback of uneven heat distribution, this method remains relevant as a physical modification technique aligned with green processing principles in the food industry.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in supporting the national economy, particularly in the fisheries sector. This study was conducted through a direct interview with a fish farming MSME, GG Sawah Farm, managed by Legiono. The purpose was to explore the dynamics of catfish and pangasius farming businesses, including business history, capital needs, marketing strategies, and the challenges faced. The findings reveal that despite its promising economic potential, the business encounters various obstacles such as feed costs, seed availability, and climate changes. However, through innovations such as the use of alternative feed, social media marketing, and product diversification into the frozen food sector, the enterprise has managed to survive and grow. This study recommends improving production efficiency, increasing financial support, and encouraging collaboration with stakeholders to enhance the sustainability and development of small-scale fish farming businesses in Indonesia.

Along with the rapid advancement of digital technology, the practice of zakat payment has also evolved, such as by making non-cash zakat payments online. Online zakat payment offers the potential to reach zakat givers and recipients more broadly, as well as to increase efficiency in the collection and distribution of zakat funds through a digital system. However, this online zakat payment system still raises debates among the public regarding the validity of its implementation and the law, which is considered unclear because the method was not found in the time of the Prophet Muhammad SAW. Therefore, this research was conducted to examine the concept, Islamic legal review, advantages and disadvantages, as well as challenges and solutions in the application of the online non-cash zakat payment system from the perspective of Islamic law. This research uses normative legal methods in qualitative form and by conducting a literature study of literature or library materials. The findings of this research show that online non-cash zakat payments are sharia-acceptable as long as they fulfill the pillars and conditions of zakat and are carried out by official amil zakat institutions or platforms affiliated with amil zakat institutions.

The purpose of this study is to assess the computational thinking skills of fourth-grade elementary students within the framework of mathematics instruction. Computational thinking is a crucial 21st-century competency that should be cultivated from an early age, particularly in solving mathematical problems. This study adopts a descriptive quantitative method using a written test instrument developed based on four key computational thinking components: decomposition, pattern recognition, abstraction, and algorithmic processes. The participants in this research were fourth-grade students from a selected elementary school. The results indicate that most students demonstrate a moderate level of computational thinking. Among the assessed indicators, decomposition was the most successfully achieved, while algorithmic thinking was the least mastered. These results highlight the importance of integrating contextual and problem-based learning strategies to further enhance students’ computational thinking abilities in mathematics education.

This article discusses the importance of a multicultural approach in guidance and counseling, in a country rich in cultural diversity. Within this context, counselors are expected to understand and appreciate the cultural differences faced by clients, including different values, norms, and perspectives. Multicultural counseling not only increases the effectiveness of the counseling process, but also creates a safe counseling environment for clients to express themselves. By understanding the client's cultural background, the counselor can minimize potential conflicts and increase confidence in the counseling relationship. This research uses a qualitative method with a literature study to explore the challenges and solutions in multicultural counseling practice. The findings of this article suggest that sensitivity to cultural diversity is essential for successful inclusive and responsive counseling.

The 2024 data breach incident at Indonesia's National Data Center (PDN) marked a major crisis in the governance of national cybersecurity. This study examines the causes, threats, proposed solutions, and the roles of both the government and the public in responding to such breaches. The research employs a literature review and media framing analysis, focusing on news coverage and government policy responses. Findings indicate that systemic vulnerabilities, inadequate infrastructure readiness, and human factors are the primary causes of the breach. The resulting threats include economic and social losses, a decline in public trust, and the risk of data misuse. Proposed solutions involve strengthening regulations, enhancing technical capacity, and increasing public awareness through education. The active participation of civil society and swift government response are critical to restoring trust and preventing similar incidents in the future.
