Epistemology is a branch of philosophy that focuses on the nature, sources, methods, and limits of human knowledge. This article aims to examine the concept of epistemology within the context of the philosophy of science, its scope, and its relevance to the development of modern scientific thought. This study employs a descriptive qualitative approach using a literature review method thatdraws upon both classical and contemporary sources in the field of the philosophy of science. The findings indicate that epistemology encompasses four main domains: the sources of knowledge, the methods of acquiring knowledge, the validity and truth of knowledge, and the limits of human understanding. In the modern context, epistemology faces new challenges such as technological advancement, scientific interdisciplinarity, and the relationship between local and global knowledge systems. The practical implications of epistemology are also evident in education through constructivism, inquiry-based learning, and epistemological literacy. Therefore, a sound understanding of epistemology serves as a crucial foundation for developing an educational and scientific system that is critical, reflective, and contextually relevant.

The urgency of marriage as an effort to elevate human dignity and sustain life and progeny is regulated in Law Number 16 of 2019, which amends Law Number 1 of 1974 concerning Marriage. The state requires marriage registration to guarantee the validity and legal protection of the rights of married couples and their children. One important provision in this regulation is the determination of the minimum age for marriage, which is 19 years for both men and women. However, in practice, underage marriages, including unregistered marriages, still occur. This study uses a normative-empirical research method, combining written legal analysis with field data to examine the application of laws and regulations in community practice. The results show that underage marriages can be legalized by the Religious Court based on Minister of Religious Affairs Regulation Number 20 of 2019. This regulation provides legal certainty and protection of children's rights, but has also raised controversy regarding the potential legalization of early marriage. This regulation has had a significant impact on the practice of itsbat nikah anak kecil, especially at the Bulango Ulu Religious Affairs Office (KUA), by reducing unregistered marriages. However, challenges in verifying evidence, socio-cultural pressures, and the normalization of early marriage remain major obstacles that must be overcome through education and cross-sector collaboration.

This community service initiative was designed to increase students' enthusiasm for Arabic language instruction by applying singing techniques in co-curricular activities at Hasanka Islamic Elementary School.

MP3 audio files are often used in a variety of fields, but they are prone to security risks such as eavesdropping and illegal access. This study proposes a super encryption method by combining the algorithms of Rivest Shamir Adleman (RSA) and ElGamal to improve the protection of audio data. RSA was chosen for its efficiency and ease of implementation, while ElGamal offers a high level of security through discrete logarithmic complexity. The combination of the two is expected to address the weaknesses of each algorithm and strengthen file security. The system is developed using the Python programming language with the Visual Studio Code environment. The encryption process is done in layers: MP3 files are first encrypted with RSA, and then the results are encrypted again with ElGamal. The decryption is done in reverse order. Tests are conducted with various MP3 file sizes to measure the effectiveness and performance of the system. The results show that this method is able to secure audio files so that they cannot be accessed without the private keys of both algorithms. Although processing times are increased compared to single encryption, the level of security obtained is much higher. This approach can be an effective solution for protecting digital audio data, particularly MP3 format, and could potentially be applied to a wide range of other data types that require a high level of security.

This research analyzes the implementation of Occupational Safety and Health (K3/OSH) in the automation project of the Vacuum Pan machine at a sugar factory in Indonesia. The Vacuum Pan machine automation project poses high potential hazards due to its involvement with electrical systems, high-pressure pipes, and the installation of electrical and automatic control systems. The research methods used were daily direct observation in the field and interviews with the factory's safety (EHS) personnel, project workers, and interns for one month, from July 7 to August 8, 2025. The results show that K3 planning, such as the availability of HIRADC documents, SOPs, Safety Plans, and K3 facilities (APAR, evacuation routes, safety signs), has been well-implemented and adheres to applicable standards. K3 supervision activities include Safety Inspection (routine twice a week), Safety Patrol (daily and spontaneous), and Safety Talk or Toolbox Meeting (routine every Wednesday). However, the aspect requiring improvement is worker discipline, particularly in the use of Personal Protective Equipment (PPE) and adherence to Standard Operating Procedures (SOPs), which were recorded at compliance frequencies of 65% and 60%, respectively. Workers' response to hazardous situations was also found to be less responsive (50%). In conclusion, while K3 planning and facilities are adequate, the overall K3 implementation needs to be optimized through increased supervision and the establishment of a disciplined culture regarding PPE and SOPs.

The utilization of Quick Response Code Indonesian Standard (QRIS) by Micro, Small, and Medium Enterprises (MSMEs) in Indonesia has an important role in encouraging digitalization of transactions and improving financial recording and reporting. The background of this study is the need for MSMEs to adapt to the development of digital payment technology, especially in the midst of accelerated digitization triggered by the COVID-19 pandemic. Although QRIS provides various benefits, such as ease of transactions and automatic recording, there are still a number of obstacles such as limited digital literacy, uneven infrastructure, and concerns related to cybersecurity, especially in remote areas. This study uses a qualitative method with a case study approach to SMEs that have adopted QRIS in several regions in Indonesia. Data were collected through field observations, and documentation studies related to the use of QRIS in business activities. Data analysis was conducted thematically to explore in-depth understanding of the experiences, challenges, and benefits felt by MSME actors in the use of QRIS. The results showed that QRIS makes it easier for MSMEs to process payments and automatic digital transaction recording, thereby increasing the accuracy and transparency of financial statements. However, limited access to electricity, digital devices, and digital security literacy are significant barriers to optimal implementation of QRIS. The security aspect of digital transactions is an important concern for MSMEs, who need further education and technical support. Thus, strengthening digital literacy, improving infrastructure, and strict cybersecurity regulations are urgently needed to encourage wider and inclusive adoption of QRIS among MSMEs in Indonesia.

Puddles after rainfall remain a common environmental issue in urban areas, including in higher education environments. At Sultan Syarif Kasim State Islamic University (UIN Suska) Riau, post-rain flooding often disrupts academic activities and reduces comfort among campus residents. This study aims to identify the locations of post-rain flooding, analyze the contributing factors, and explore the perspectives and proposed solutions of the campus community through a participatory mapping approach. The study employed a qualitative descriptive method supported by Geographic Information System (GIS) spatial analysis. Data were collected through field observations, interviews with students, lecturers, and staff, and GPS-based flood point mapping. Results show that puddles frequently occur in main parking areas, inter-faculty roads, and flat areas around the Student Activity Center. The main causes include inadequate drainage systems, clogged channels due to waste, limited infiltration zones, and impervious surfaces. The campus community suggested solutions such as improving drainage, constructing infiltration wells, and adopting the green campus concept. Participatory mapping proved effective not only for identifying environmental problems but also for raising ecological awareness and shared responsibility among the academic community.

Artificial intelligence (AI) has developed rapidly in recent years, making judgments and executing tasks in ways comparable to decisions made by the human brain. These technological advances allow AI to replace or complement human work in various fields, but they also raise complex legal questions regarding accountability for the actions it performs. This study employs a normative juridical research methodology, which emphasizes the analysis of laws and regulations, concepts, principles, and legal theories, using literature as the primary data source. The findings show that AI, despite its advanced capabilities, remains a legal object rather than a legal subject. In accordance with Government Regulation No. 71 of 2019 on the Implementation of Electronic Systems and Transactions in Indonesia, AI cannot be considered a legal entity with independent rights and obligations. Consequently, AI cannot be held legally accountable for its actions, as it operates under human creation, programming, and direction. Responsibility for any consequences arising from the use of AI lies with the individuals or institutions that develop, operate, and control it. This study highlights the importance of establishing a clear legal framework to regulate AI applications, ensuring that technological innovation aligns with legal certainty and accountability. It concludes that while AI may imitate human decision-making, it lacks autonomy in the legal sense and therefore cannot bear responsibility under positive law.

Economic forecasting is becoming increasingly important year after year, especially during crises such as the pandemic of COVID-19 and the Russia-Ukraine war. Its development can be seen from the use of basic statistical models to the increasingly widespread use of machine learning technology. Economic forecasting plays an important role in helping to formulate policies and is also a reliable tool for researchers in dealing with uncertainty. Global crises, such as inflationary pressures due to the pandemic and supply chain disruptions from the Russia-Ukraine conflict, have prompted increased research in this field in an effort to anticipate economic shocks and emphasize the urgency of forecasting to prepare strategies for dealing with future uncertainty. This literature review uses the Scopus database with 2561 publications from 2020 to 2025, analyzed using R Studio with a bibliometrix approach (specifically biblioshiny) and VOSviewer to map relevant thematic connections. This analysis shows that economic forecasting is greatly influenced by market uncertainty and geopolitical factors, and at the same time influences public policy formulation and financial stability. Research contributions from Indonesia are still limited, with only 40 documents, thus emphasizing the need to strengthen economic forecasting studies in Indonesia to support monetary policy and national financial stability.

The integration of green marketing into corporate strategies represents a paradigmatic shift in responding to global sustainability issues while enhancing competitiveness and socio-ecological commitment.
