The development of science and technology generally brings positive impacts in terms of convenience in various human activities, but on the other hand, it also leads to negative consequences such as an increase in waste. One of the significant wastes produced from construction activities, including building and house construction, is feldspar, which typically comes from leftover ceramic materials. Feldspar is a type of waste that is difficult to decompose naturally and has no economic value, often accumulating and polluting the environment. Therefore, innovation is needed to utilize this waste to create value. This study aims to use feldspar powder as a replacement for fine aggregates in K-200 grade concrete mixtures. The research method involved mixing feldspar powder in specific proportions as a substitute for sand, followed by a series of tests, including compressive strength and flexural tests, to determine the feasibility and performance of the resulting concrete. The results indicate that the use of feldspar powder as a fine aggregate produces a concrete mixture with satisfactory mechanical characteristics, meeting the K-200 concrete standards. These findings not only provide an alternative environmentally friendly material but also offer a solution to reduce ceramic waste, contributing positively to sustainable construction.

The rapid growth of digital financial technology has introduced new economic instruments that require re-evaluation through the lens of Islamic economic law, one of which is Bitcoin. This study aims to analyze the legal standing of Bitcoin as a means of transaction and investment using a normative legal approach. Data were obtained through extensive literature review involving primary and secondary sources, including Islamic jurisprudence, maqāṣid al-sharī‘ah, qawā‘id fiqhiyyah, official fatwas, and contemporary technological and economic studies. The analysis employed normative and reconstructive methods to assess the compatibility of Bitcoin’s characteristics with the principles of Islamic law. The findings indicate that Bitcoin may be classified as a form of digital māl because it possesses utility, can be lawfully owned, and is tradable within open market mechanisms. However, its extreme price volatility, limited public acceptance, and absence of state-backed legitimacy make it unsuitable as a lawful medium of exchange in Islamic transactions. Conversely, Bitcoin may be permitted as an investment instrument under strict conditions, provided the activity avoids speculative motives, ensures transparency, and follows prudent financial conduct. Based on these assessments, this study concludes that Bitcoin is more appropriately categorized as a digital commodity rather than a transactional currency. This research contributes conceptually to the development of sharia-compliant crypto-asset regulations and opens avenues for further exploration on designing more stable and ethically aligned digital financial instruments.

Breakups often trigger psychological conflict ranging from stress, anxiety, depression, to risky behavior that have an impact on individual well-being and the social environment. This study explores the role of law in preventing, responding to, and recovering such psychological impacts through an interdisciplinary approach. The methodology used is a normative-juridical study combined with a literature review of clinical psychology and mental health policy. The findings show that the legal framework can function on three levels: (1) preventive, through the guarantee of the right to mental health, digital literacy, and platform governance to prevent post-breakup online harassment; (2) protective, through victim protection mechanisms against psychological violence, stalking, doxing, and the dissemination of non-consensual intimate content; and (3) curative, with a referral scheme for counseling services, the provision of legal aid, data confidentiality guarantees, and restorative justice instruments centered on victim recovery. However, there are implementation gaps, including the lack of standardization of psychological assessments in the legal process, limited access to services at the grassroots level, and coordination between institutions that are not optimal. This article recommends the integration of mental health protocols in the law enforcement process, evidentiary guidelines for psychological violence, as well as cross-sectoral collaboration with psychological service providers and digital platforms. The main contribution of this study is the mapping of a comprehensive legal intervention framework for post-breakup psychological conflicts.

The weakness of the scientific tradition among Muslims and the complex problems of Islamic education have left Islamic education consistently lagging behind, theoretically unable to provide answers to the demands of liberalism and humanization. A reconstruction of the epistemological structure appropriate to the current context is necessary. This paper aims to analyze and critique Ibn Rushd's epistemology. The article is a study of the figure to look specifically at his epistemology with critical reasoning to produce findings on the research questions. The results of the study show that Ibn Rushd's epistemology is a critical synthesis of Greek philosophy and Islamic religion, which places reason and revelation as complementary paths to true knowledge and happiness in the afterlife. He critiques the thought that separates the two, especially by emphasizing the importance of scientific methods and rational reasoning, and highlights its critical aspects through criticism of Al-Ghazali and the development of the theory of the unity of the intellect which has had a significant impact on philosophical thought and education. Ibn Rushd's thinking sparked the Averroist movement in Europe, which later ushered in the Renaissance. His epistemology had positive implications for the development of Islamic education, encouraging the development of reason-based knowledge and scientific analysis. His concept of the unity of philosophy and religion, along with his emphasis on the scientific method, inspired scientists in the development of general knowledge in the modern era .

Acne vulgaris (AV) is a common dermatological condition affecting adolescents and young adults, with multifactorial causes including hormonal influences, increased follicular keratinization, excessive sebum production, and colonization by Cutibacterium acnes. External factors, particularly skincare behavior, are also considered to play an important role. The use of skincare products that are unsuitable for skin type or contain comedogenic ingredients such as mineral oil, lanolin, and certain silicones may clog pores and exacerbate acne. This study aimed to analyze the relationship between skincare product selection and usage behavior, types of skincare products used, and frequency of use with the occurrence of acne vulgaris among female medical students of the Faculty of Medicine, Universitas Sumatera Utara, cohorts 2022–2024. An analytical observational study with a cross-sectional design was conducted. Primary data were collected through an online questionnaire, while secondary data were obtained from the student directory. A total of 90 respondents were selected using stratified random sampling. Data analysis was performed using the Chi-square test. The results showed a significant association between skincare product selection and usage behavior and the occurrence of acne vulgaris (p = 0.043), as well as between the type of skincare products used and acne incidence (p < 0.001). However, no significant relationship was found between the frequency of skincare product use and acne vulgaris (p = 0.116). These findings indicate that appropriate product selection and type are more influential in acne development than usage frequency.

Musculoskeletal Disorders (MSDs) complaints in muscles, joints, and soft tissues can be caused by poor posture, repetitive movements, and excessive physical load. In the wet cake-making industry, workers often sit or stand for long periods, bend, and perform monotonous hand movements, which increases the risk of MSDs. The impact includes decreased work comfort, productivity, and quality of life. This study aims to assess the ergonomic risk level in wet cake-making workers and identify the relationship between work activities and MSD complaints. The method used is descriptive quantitative research with a cross-sectional design, involving 45 workers at Kue X Silaberanti. Ergonomic risk was assessed using the REBA method, while MSD complaints were measured using the Nordic Body Map questionnaire. The results show that in the mixing process, 58.8% of workers experienced a very high risk of MSDs. In the molding and baking processes, 52.9% and 68.8% of workers, respectively, were at high risk. The most frequent complaints were pain in the back, neck, shoulders, arms, and wrists due to poor posture and repetitive movements. To reduce the risk of MSDs, workers need to improve their posture, use ergonomic aids, rotate tasks, and undergo training in safe working techniques.

Radiographic examination plays a crucial role in visualizing internal body structures for diagnostic purposes. One of the radiographic assessments frequently performed is the Acromioclavicular (AC) joint projection, which is used to evaluate abnormalities such as joint widening, subluxation, and dislocation. This study aimed to compare the image quality of the AC joint using the Anteroposterior (AP) projection with a 3-kg load and without load. The study was conducted in the Radiology Laboratory of STIKES Borneo Nusantara using a conventional X-ray system with a quantitative descriptive case-study approach. Data were collected through observation and questionnaires administered to 10 research subjects, including radiographers and patient participants. The findings demonstrated that the AP projection with a 3-kg load produced clearer visualization of the AC joint, particularly in widening of the joint space and separation between the humeral head and glenoid cavity. The average image quality score using load was 3.5 (good), compared with 2.9 (poor) for the projection without load. The study concludes that applying a 3-kg load improves anatomical visualization of the AC joint and is recommended for cooperative patients to enhance diagnostic accuracy.
