This study explores the development of low-carbon concrete by integrating industrial waste materials and CO₂-absorbing minerals to reduce carbon emissions in the construction industry. The research investigates various mix ratios involving fly ash, slag, and CO₂-absorbing minerals, aiming to optimize both performance and sustainability. Experimental methods included compressive strength testing, carbon emission measurement, and durability evaluation. The results indicate that low-carbon concrete formulations achieve up to 45% reduction in carbon emissions compared to conventional concrete, which uses Portland cement. Despite a slight decrease in compressive strength, the optimal mix reached 34 MPa, which is sufficient for structural applications. Durability testing revealed that concrete with CO₂-absorbing minerals showed improved long-term performance compared to other formulations. The findings highlight the potential of using industrial waste materials and carbon capture technologies to create more environmentally sustainable concrete while maintaining necessary structural properties. This study contributes to the growing demand for eco-friendly construction materials and supports the implementation of low-carbon concrete in large-scale industrial applications. Further optimization of mix ratios and long-term performance studies are recommended for broader adoption in the construction industry.

The apple cider vinegar fermentation process requires careful monitoring and control of variables such as pH, alcohol content, and amount of acetic acid.  This research adopts Fuzzy Logic Control by utilizing the MQTT communication protocol, pH, alcohol and water pump sensors, as well as solenoid valves and DC motors as actuators.  This Internet of Things (IoT) based solution provides real-time monitoring information on the fermentation process.  The results showed that the test system succeeded in maintaining a stable pH of around 3.9-4.0 during the initial stages of fermentation, while industrial data showed greater variations.  Alcohol content increased consistently in the test system, in contrast to the spike on day 7 in industry data.  At the formulation stage, the pH dropped to 3.68 in the test system, while the industry maintained 3.70.  At medium and slow mixing stages, the test system showed a significant decrease in pH and a consistent increase in alcohol.  At the harvest stage, the pH was lower in the test system compared to industrial, with slightly higher alcohol content.  Test results show that the implementation of this system can reduce the fermentation process time by up to 2 days faster compared to conventional methods.  This conclusion shows that IoT-based systems are able to provide better control and monitoring than conventional systems, so they have great potential for wider adoption in the apple vinegar fermentation industry to increase production effectiveness.

The aim of this study was to assess the impact of octopus fishing gear use on coral reef ecosystems in Simeulue District. The research was conducted in May 2024, with research methods combining in-depth interviews and field observations.

Although fishers recognize the importance of ecosystem sustainability, challenges in adopting environmentally friendly practices still exist, including a lack of law enforcement and education. The conclusion of this study emphasizes the need for collaboration between the government and fishing communities in formulating more effective fisheries resource management policies, as well as the importance of training in sustainable fishing techniques. The study provides recommendations for the implementation of stricter regulations on the use of fishing gear, as well as encouraging active participation of fishers in fisheries resource management.

Fiqh is not a revelation from heaven, but rather the result of ijtihad which is a product of human thought. Therefore, it is important to ask critical questions such as: who defined it, for what purpose, in what social context it was formulated, in which geographical area, and with what epistemological approach. These factors greatly influence the process of forming fiqh. In other words, fiqh was not born in a vacuum, but rather developed along with the course of history and was influenced by the dynamic interaction between thinkers and the socio-cultural and socio-political environment in which they were located. This article uses a literature review methodology to examine the historical and social dynamics in the formation of fiqh. Unfortunately, fiqh that is developing among Muslims today is still heavily influenced by medieval works, especially those from Middle Eastern scholars. This condition shows the need for renewal and reactualization of fiqh according to the context of the contemporary era and society.

Teacher competency is very important, so a teacher must have the ability to professionally improve the implementation of their duties in the field of education. This is useful for educating the nation's children. This feasibility study aims to formulate policies related to improving the quality of education which is focused on the conditions of adequate madrasah ibtidaiyah (MI) teachers based on the professional competence possessed by each teacher. This research uses qualitative methods with cross sectional techniques to analyze data for each MI teacher based on academic qualifications according to the field of study they teach. The findings of this research show that there are still many MI teachers who do not have undergraduate academic qualifications as stipulated in Law No. 14 of 2005 concerning Teachers and Lecturers. The ratio between the number of elementary schools (SD) and MI (both private and public) in Tampan District is 5:1; or the number of elementary schools is 41 consisting of 31 state elementary schools and 10 private elementary schools, while the number of new MIs is 8, all of them have private status. It can be argued that public interest and the government's response to MI is still relatively low due, among other things, to the relative lack of competent teachers.

Cosmetics have varied purposes, including cleansing, increasing brightness, changing appearance, and protecting or maintaining certain conditions. The applicable cosmetics regulations are explained in the BPOM provisions, which mandate registration before cosmetics can be used by consumers. In this research, the results of two literature reviews are presented that support this statement. The first study by (Chandra Adi Gunawan Putra, 2023) shows that the need for state involvement in protecting consumers arises because of the power imbalance between business actors and consumers. The second study by (Ribka Amanda Dera, 2019) the regulation of cosmetic products has been regulated by BPOM number 12 of 2020 article 2 paragraph 1 which emphasizes that cosmetics producers must ensure that their products which will be distributed both domestically and abroad meet the criteria, safety and security standards. benefits, quality marking, and claims. The results of both studies show that the importance of terms and conditions related to cosmetics are under law and regulated in the Republic of Indonesia Constitution, the Health Law, provisions issued by the Minister of Health and decisions taken by the Head of the Republic of Indonesia Food and Drug Supervisory Agency and in BPOM regulations starting from formulation to product withdrawal. So that any party who commits an illegal act by producing or distributing pharmaceutical or cosmetic products without a permit will receive applicable sanctions in accordance with legal provisions.    

Hypertension, often called the "silent killer," is a leading non-communicable disease contributing to high mortality and morbidity, particularly in the elderly. As individuals age, peripheral blood vessel elasticity decreases, increasing vascular resistance and leading to systolic hypertension, commonly seen in older adults. Hypertension requires long-term treatment, which can result in non-compliance among elderly patients. Family support plays a crucial role in assisting and encouraging adherence to treatment regimens. This quantitative correlation study, with a cross-sectional approach, aimed to examine the relationship between emotional family support and treatment compliance in elderly hypertensive patients. The study was conducted at the Sei Agul Health Center, with a sample size of 65 elderly individuals selected using the Slovin formula and purposive sampling technique in October 2023. The Morisky Medication Adherence Scale (MMAS-8) was used to measure treatment compliance, while the emotional support instrument was developed by the researcher. Data were analyzed using the chi-square test, showing a significant relationship between emotional family support and treatment compliance (p-value < 0.05). The findings conclude that emotional support from family positively influences the compliance of elderly patients undergoing hypertension treatment at the Sei Agul Health Center. Health workers are encouraged to involve families in supporting hypertensive patients to enhance treatment outcomes.

The United Islamic Cultural Center of Indonesia (UICCI) or the United Islamic Cultural Center Foundation in Indonesia is an Islamic organization that operates in the social and religious fields. This foundation is an Islamic social and religious institution that produces Al-Quran Hafiz who applies the Al-Quran and Sunnah in everyday life while directing them to do good deeds with their knowledge. The UICCI Foundation is better known as Pondok Pesantren Syarief Medan which is a branch of the IFA (International Fratenity Association) or international fraternity foundation in Turkey. The history of the founding of the Central UICCI Foundation in Turkey or the Sulaimaniyah Institute began after the fall of the Ottoman Caliphate in 1924, the Turkish regime under the leadership of the nationalist figure Mustofa Kemal Attaturk began to introduce the ideas of nationalism and secularism, or rather laicism. This is an interesting study considering that Islamic boarding schools are traditional Islamic educational institutions originating from Indonesia and UICCI is a branch of Islamic education from Turkey. Because it is a branch of the Turkish Islamic boarding school, it has its own way of learning which is different from Islamic boarding schools in Indonesia in general. The differences lie in the teaching system which is controlled by the center in Turkey, the rules are based on Sufism, the students' learning activities are integrated with the Turkish language, Turkish culture is introduced to the students and the full scholarship for further education in Turkey is given to the students. In this research there are three problem formulations, namely: History and development of the UICCI Syarief Medan Foundation, dynamics, and its contribution to students and society. The approach used by researchers is Sociology. The theory used is Continuity and Change by Jhon Obert Voll. The method used is the historical method, which includes four steps, namely heuristics, verification, interpretation and historiography. The results of this research show that the UICCI Syarief Islamic Boarding School in Medan has a distinctive form and is different from Islamic boarding schools in general. The differences can be seen from the activities at the boarding school which are based on Sufism and tarekat which are followed by Islamic boarding school students, an integrated teaching system with Turkish language and Tekamul education (scholarships for further Islamic education to Turkey). Apart from that, the dynamics that occur at the UICCI Syarief Islamic boarding school can be seen from an educational and economic perspective, namely making UICCI Syarief become the center of Tadris for the Sumatra Island branch and from an economic perspective it can be seen from what was initially free to paid. In terms of contribution, this foundation only focuses on students, preparing student go to Tekamul.

The creative industry is an industry that focuses on the creation and exploitation of intellectually owned works, one of which is fashion design, including t-shirts. The current condition of society, both individuals and groups, are now starting to build their brands with the innovation and creativity they build, including Ndlodok T-shirts. This community service is the second stage, namely to introduce ndlodok t-shirts to the community. The initial offer of the "Ndlodok" T-shirt was to formulate a library-based "Ndlodok" T-shirt with characteristics of the Mojokerto dialect with the hope of opening up a new market. Apart from that, the product would become a souvenir that consumers were looking for because it had become a characteristic of Mojokerto UMKM. In facing the rigors of UMKM businesses which are increasingly competitive, "Ndlodok" T-shirt products do not experience problems in the middle of their journey, at this early stage it is necessary to introduce them as a reference for "Ndlodok" T-shirts in carrying out promotional activities.
