Abstract

Indonesia ranks second in the world and Bandar Lampung City is the region with the highest TB incidence in Lampung Province with a treatment success rate that is still below the national target. This study aims to analyze the risk factors associated with the incidence of pulmonary TB in the Kedaton Community Health Center Working Area of ​​Bandar Lampung City using a quantitative analytical study with a case-control design. The study sample consisted of 40 cases (smear-positive pulmonary TB patients) and 40 controls (closest neighbors without TB) taken using a consecutive sampling technique, where data were collected through interviews, observations, and measurements using questionnaires and physical measuring instruments at home. The results of the bivariate analysis showed that employment status (p = 0.024) and bedroom ventilation (p = 0.040) had a significant relationship with the incidence of pulmonary TB, while the results of the multivariate analysis using multiple logistic regression showed that gender (p = 0.015) and bedroom ventilation (p = 0.009) were significantly related variables. The conclusion of this study determined that bedroom ventilation was the most dominant variable associated with pulmonary TB incidence, with inadequate ventilation having a 3.91-fold increased risk (OR=3.91; 95%CI=1.41-10.94) compared to adequate ventilation after controlling for gender.

Abstract

This study examines the role of transformational leadership in improving the quality of students’ health services at Al-Jauharen Islamic Boarding School in Pelayangan District, Jambi City. The problem addressed in this research is the limited quality of health services for students, which is influenced by constraints such as inadequate facilities, limited medical personnel, and suboptimal sanitation conditions. The objective of this study is to analyze how transformational leadership contributes to enhancing health service quality, identify supporting and inhibiting factors, and explore the efforts undertaken by the boarding school leadership. This research employs a qualitative approach with a descriptive method. Data were collected through observation, in-depth interviews, and documentation involving key informants such as the head of the boarding school, administrators, students, and related stakeholders. The findings reveal that transformational leadership is reflected through idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. This leadership approach has successfully improved the quality of students’ health services through integrated health programs, the empowerment of student health cadres (Santri Husada), the promotion of clean and healthy living behaviors, and collaboration with external institutions such as community health centers and the local health office. However, challenges remain, including limited infrastructure and the absence of permanent medical staff. Overall, transformational leadership plays a significant role in creating a healthy, religious, and sustainable boarding school environment.

Abstract

Penelitian ini dilatarbelakangi oleh kebutuhan pengembangan sabun organik yang tidak hanya berfungsi sebagai pembersih, tetapi juga memberikan manfaat kesehatan kulit melalui kandungan bahan alami. Tujuan penelitian adalah menganalisis pengaruh variasi konsentrasi Virgin Coconut Oil (VCO) dan ekstrak kunyit terhadap kualitas sabun padat, serta mengevaluasi sifat fisik dan kimianya. Metode yang digunakan adalah pembuatan sabun dengan proses cold process menggunakan VCO, minyak zaitun, shea butter, madu, dan lemon sebagai bahan tambahan. Uji yang dilakukan meliputi organoleptik, pH, kadar air, tinggi dan stabilitas busa, serta kadar asam lemak bebas (ALB). Hasil penelitian menunjukkan bahwa peningkatan konsentrasi VCO memperbaiki tinggi dan stabilitas busa serta menurunkan kadar air, sementara penambahan ekstrak kunyit berlebih dapat meningkatkan kadar ALB karena mengganggu efisiensi saponifikasi. Nilai pH sabun berada pada kisaran 7–8, sesuai standar SNI untuk keamanan kulit. Formulasi optimal diperoleh pada penggunaan VCO 30–35 mL dengan ekstrak kunyit 1–3 mL, yang menghasilkan sabun dengan karakteristik fisik dan kimia paling stabil. Keterbaruan penelitian ini terletak pada formulasi sabun berbasis VCO dan kunyit dengan penambahan kombinasi bahan alami lain berupa minyak zaitun, shea butter, ekstrak lemon, dan madu, sehingga menghasilkan produk yang lebih kaya manfaat, lembut di kulit, serta ramah lingkungan.

Abstract

Korong Pasa Limau is one of the villages in Nagari Parit Malintang, where the village has a surau (prayer hall) that has just been built and is located among the Guci community. The problem faced by the residents of Korong Pasa Limau is the safety of residents who want to pray at the newly built surau, named Surau Sungsang. Before Surau Sungsang was built by the residents of Korong Pasa Limau, the korong already had a surau located downhill, so residents who wanted to pray had to walk down and were at risk of falling or slipping on the descending path leading to that surau. Student Real Work Lecture (KKN-PPM) community service activities are carried out to solve problems that occur in the environment. One of them is by providing public facilities in the form of lighting at Surau Sungsang for residents to be able to start worshiping there. Students from Group 22 of KKN-PPM UNES 2024 installed lighting for Surau Sungsang using an electric power source from PLN, with a total of 8 light installation points at Surau Sungsang, Korong Pasa Limau.

Abstract

Sustainable education has become one of the strategic agendas in global development, positioning education as a primary instrument for building an inclusive, equitable, and future-oriented society, as emphasized in the Sustainable Development Goals (SDGs), particularly Goal 4 on quality education. In the Indonesian context, Islamic education holds a strategic position as it not only contributes to the development of students’ intellectual capacities but also plays a significant role in character formation, moral values, and social sustainability. However, the implementation of sustainable education policies within the Islamic education sector continues to face various structural and conceptual challenges, including the dualism of the education system, policy fragmentation among institutions, disparities in educational quality and access, and the limited synergy among stakeholders in educational governance. These conditions indicate a gap between the paradigm of sustainable education, which requires a holistic approach, and the practice of Islamic education policy, which remains relatively partial and sectoral. This article aims to analyze the construction of Islamic education policy from the perspective of sustainable education and to formulate an integrative policy model that aligns with the characteristics and needs of Islamic education in Indonesia. This study employs a library research method using a conceptual approach and critical analysis of various academic literature, policy documents, educational regulations, and research findings related to sustainable education, Islamic education policy, systemic approaches, and the concept of multilevel governance. The analysis is conducted to identify the limitations of existing policy paradigms while exploring strategic principles for developing sustainable Islamic education governance. The findings reveal that Islamic education policies in Indonesia have not yet fully reflected the principles of sustainability, as they remain largely focused on institutional quality improvement, administrative management, and compliance with educational standards. Meanwhile, the aspects of value integration, system sustainability, and cross-stakeholder collaboration have not become the fundamental basis of policy development. Based on these findings, this article proposes an Integrative Model of Sustainable Education Policy built upon three main dimensions: (1) value integration, which connects Islamic educational principles with global sustainability values; (2) system integration, which harmonizes various educational subsystems through a holistic approach; and (3) policy integration, which strengthens coordination and collaboration among different levels of government and educational actors. This model is characterized as adaptive, value-based, collaborative, and long-term oriented, making it a conceptual framework for transforming Islamic education policies into a more responsive system that addresses social change, global challenges, and the needs of future generations.
