This study aims to examine the role of Self-Determination in improving students' learning persistence in the digital era. Self-Determination Theory explains that long-lasting learning motivation arises from within the individual, which is influenced by the fulfillment of three basic psychological needs: autonomy, competence, and relatedness. Amidst the challenges of the digital era, such as social media distractions, students are required to have internal motivation to remain diligent in learning. Through a qualitative approach, the researcher interviewed five students in depth. The results showed that students were able to maintain learning persistence because of personal goals, parental support, and previous academic success experiences. The three aspects of Self-Determination have been shown to play an important role in shaping students' learning persistence despite facing digital disruptions. This study shows the importance of strengthening internal motivation to support learning success in the digital era.

The low learning outcomes of students in Biology learning at SMA Negeri 1 Tutuyan is the background for the need for learning innovations that are able to increase active participation and conceptual understanding. This study aims to analyze the effectiveness of the Group Investigation learning model in improving student learning outcomes in Cell materials. The research used a pseudo-experiment method with a one group pretest-posttest design. The research sample amounted to 35 students from class XI Science who were selected purposefully. The instruments used were multiple-choice tests, pre-tests and post-tests of 25 questions for each test. The results showed an increase in the average score from 23.14 in the pre-test to 83.14 in the post-test. Inferential data analysis using the t-test showed a t-calculated value of 89.55, far above the t-table at a significance level of 5%. The category of student learning outcomes has also undergone significant changes, from a very low majority to a high and very high majority. The application of the Group Investigation model encourages students to be active in investigation, group discussions, and independent learning, which strengthens their collective and individual mastery of the material. These findings prove that the Group Investigation model is effective in improving learning outcomes, and can be implemented as a learning strategy in the Independent Learning Curriculum. This study contributes to the development of cooperative learning models in the context of Biology learning at the high school level, and can be replicated in other materials and levels to strengthen its effectiveness.

The performance of the Hajj pilgrimage is one of the pillars of Islam that must be fulfilled by Muslims who possess the ability (istita'ah). Due to the overwhelming number of applicants and the restrictions on the number of pilgrims allowed to depart each year imposed by the Saudi Arabian government, the Ministry of Religious Affairs of the Republic of Indonesia has limited the departure of prospective Hajj pilgrims through a quota system and the allocation of waiting numbers known as "nomor porsi" (quota numbers). One consequence of this situation is that some prospective Hajj pilgrims who have registered and received their quota numbers may pass away before their departure. To address this issue, the Director General of Hajj and Umrah Implementation has issued Decree Number 130 of 2020, which allows for the transfer of quota numbers to one of the heirs of a deceased prospective Hajj pilgrim who did not have the opportunity to perform the pilgrimage. The findings of the study indicate that the Hajj quota of a deceased prospective pilgrim is part of their rights that fall into the category of inheritance. When such a right falls into this category, it can become an inheritance that must be divided among heirs who meet the requirements.

The community service activity was carried out in Lima Puluh Subdistrict, Batu Bara Regency. The partner in this activity was the Regional Development Planning, Research, and Development Agency. The main problem faced by the partner is the absence of an official slaughterhouse building in Batu Bara Regency. Until now, only independently managed slaughterhouses owned by the community have been used as animal slaughtering facilities. However, these slaughterhouses can only accommodate a limited number of slaughters. Moreover, issues related to poor meat hygiene and cross-contamination during slaughtering and packaging processes for consumer distribution are still frequently encountered. The solution to this problem is to establish an official slaughterhouse in Batu Bara Regency that meets both administrative and technical requirements. The purpose of this activity is to provide understanding to the community and stakeholders regarding the utilization of an official slaughterhouse and the importance of having a standardized slaughterhouse. The expected outcomes of this community service activity are: (1) to increase public knowledge in Batu Bara Regency regarding the importance of RPH utilization, (2) to enhance awareness of providing meat that is Safe, Healthy, Whole, and Halal (ASUH), and (3) to provide recommendations to the local government regarding the planning and development of an official slaughterhouse.

This study aims to examine the potential and challenges of utilizing Solar Power Plants (PLTS) in Medan City, which is geographically located near the equator and receives high exposure to sunlight throughout the year. The method used is a literature review with a narrative review approach that analyzes secondary data from various journals and relevant scientific articles. The results of the study show that Medan City has an average annual horizontal global solar radiation intensity of 463.61 W/m², with the potential for electrical power that can be generated from rooftop solar panels reaching 748.57 MW (monocrystalline), 598.85 MW (polycrystalline), and 299.43 MW (thin film). This potential is comparable to the capacity of large-scale power plants. The use of PLTS contributes to reducing carbon emissions, increasing energy security, creating jobs, and developing the local economy. However, challenges such as high installation costs, limited suitability of roof structures, and low public awareness are still major obstacles in the implementation of this technology. Therefore, synergy is needed between government policies, public education, and technological innovation to optimize the use of solar energy in urban areas such as Medan.

The transformation of the modern labor market has posed significant challenges for young people, particularly in the form of career uncertainty, excessive work flexibility, and the mismatch between education and labor market demands. This study aims to explore how Indonesian youth respond to these conditions through the lens of ambivalence and resilience theories by Colombo & Rebughini. The research uses a qualitative method with in-depth interviews involving two university graduates working in fields unrelated to their academic backgrounds. The findings reveal that the lack of job stability, economic pressure, and educational mismatch drive young people to develop various adaptive strategies. These include personal resilience such as introspection and optimism, as well as social resilience supported by family and peer networks. Furthermore, the meaning of work among youth is shifting—not merely as a source of income, but as a space for self-actualization, skill relevance, and psychological comfort. This is consistent with previous studies in SINTA-indexed journals, which emphasize that Indonesian youth today are redefining success and meaningful work within an increasingly ambivalent social landscape. The study concludes that youth are not merely passive victims of economic uncertainty but are also active agents in constructing their own narratives of work and life. Therefore, it is essential for educational institutions, industries, and the state to provide adaptive environments that allow youth to grow sustainably within a dynamic labor ecosystem.
