Abstract

Final-year students often experience high academic pressure, especially during the process of writing their thesis. In such situations, social support and hardiness are important factors that can help students manage academic stress. This study aims to examine the effect of social support on academic stress with hardiness as a mediating variable among students who are currently writing their thesis at Universitas Medan Area. This research employed a quantitative method using the Structural Equation Modeling (SEM) approach based on Partial Least Squares (PLS). The sample consisted of 250 students selected through purposive sampling. The instruments used were the adapted versions of the Academic Stress Scale (ASS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Revised Academic Hardiness Scale (RAHS). The results showed that social support had a negative effect on academic stress (β = -0.318, p < 0.05), hardiness had a negative effect on academic stress (β = -0.496, p < 0.05), and social support had a positive effect on hardiness (β = 0.440, p < 0.05).Mahasiswa tingkat akhir menghadapi tekanan akademik yang tinggi terutama saat menyusun skripsi. Dalam situasi tersebut dukungan sosial dan hardiness menjadi faktor penting yang dapat membantu mahasiswa mengelola stres akademik. Penelitian ini bertujuan untuk mengetahui pengaruh dukungan sosial terhadap stres akademik dengan hardiness sebagai variabel mediasi pada mahasiswa yang sedang menyusun skripsi di Universitas Medan Area. Penelitian ini diterapkan dengan metode kuantitatif menggunakan pendekatan Structural Equation Modeling (SEM) berbasis Partial Least Squares (PLS). Jumlah sampel sebanyak 250 mahasiswa yang dipilih melalui teknik purposive sampling. Instrumen yang digunakan terdiri dari Academic Stress Scale (ASS), Multidimensional Scale of Perceived Social Support (MSPSS), dan Revised Academic Hardiness Scale (RAHS) yang telah diadaptasi. Hasil penelitian menunjukkan bahwa dukungan sosial berpengaruh negatif terhadap stres akademik (β = -0.318, p < 0.05), hardiness berpengaruh negatif terhadap stres akademik (β = -0.496, p < 0.05), dan dukungan sosial berpengaruh positif terhadap hardiness (β = 0.440, p < 0.05). Selain itu, hardiness terbukti memediasi secara signifikan hubungan antara dukungan sosial dan stres akademik (β = -0.218, p < 0.05). Temuan ini menegaskan bahwa dukungan sosial dan hardiness memainkan peran penting dalam menurunkan tingkat stres akademik mahasiswa tingkat akhir.

Abstract

Sei Serdang Village, located in the Tangkahan Ecotourism area, is part of the Gunung Leuser National Park, a popular tourist destination. However, the Batang Serangan River, which runs through the village, poses a significant problem because its banks are filled with broken wood debris, creating a risk of flash floods. To address this, a program was initiated to train local souvenir and furniture craftsmen in Sei Serdang to manage the wood waste from the river. Through this waste management effort, production costs can be reduced, the river can be cleaned of wood debris, and the community's welfare can improve. The program employed a participatory approach, combining lectures, discussions, training, and monitoring. The stages included observation, wood waste design training, preservation, production, finishing, and final evaluation. Based on the evaluations, the craftsmen's understanding of wood waste management increased by 40%, business potential awareness by 10%, and river conservation awareness by 15%. Twenty out of forty participants successfully created innovative craft and furniture designs, while twenty-five participants utilized wood waste as production materials. Additionally, the use of wood waste led to production cost savings of up to 26.67% for souvenirs and 25% for more complex furniture items.

Abstract

The Indonesia Smart Card (KIP) Kuliah program is a government policy aimed at expanding access to higher education for students from underprivileged families. This study aims to analyze the implementation of the KIP Kuliah aspiration pathway program at Bina Prestasi Independent University, focusing on the selection process, aid distribution, and its impact on recipient students. A descriptive qualitative approach was used, with data collection through in-depth interviews, observation, and documentation. Research respondents included KIP Kuliah recipient students, supervisors, and university administrative staff. The results showed that the KIP Kuliah program has helped students from low-income families continue their higher education. The selection process is carried out transparently, but there are still technical obstacles, such as students' lack of understanding of administrative procedures and delays in fund disbursement. Additionally, students receiving the program stated that the assistance had a significant impact on reducing the economic burden on families, increasing motivation to learn, and encouraging academic achievement. This study recommends increased socialization of the program to new students, improvements in the fund disbursement mechanism, and enhanced coordination between the government, universities, and related parties. With these steps, the KIP Kuliah program is expected to operate more effectively and sustainably in supporting equitable access to higher education.

Abstract

This study aims to analyze the implementation of the Regulation of the Minister of Education and Culture (Permendikbud) No. 1 of 2021 concerning Online New Student Admissions (PPDB) at the secondary education level at SMAN 1 Sunggal. The Permendikbud is expected to increase efficiency, transparency, and equal access in accepting new students. However, in its implementation, there are various challenges that must be faced, such as limited technological infrastructure, public understanding of the online system, and inequality of internet access in several regions. This study uses a qualitative approach with a case study method that focuses on SMAN 1 Sunggal. Data were collected through interviews with the school, direct observation, and documentation related to the implementation of online PPDB. Data analysis was carried out using descriptive analysis techniques to identify various obstacles and solutions that can be applied in the implementation process of online PPDB. The results of the study show that although the online PPDB system at SMAN 1 Sunggal has been running relatively well, there are several challenges, such as inequality of internet access in certain areas and lack of public understanding regarding online registration procedures. However, this system has succeeded in reducing fraudulent practices and simplifying the administration process for accepting new students. Therefore, it is necessary to improve technological facilities and training for prospective students and parents to support the successful implementation of the online PPDB system in the future. This research is expected to contribute to the development of educational policies and improve understanding of the application of technology in the educational process in Indonesia.
