Coral reefs are vital habitats for numerous fish species, providing food, shelter, and breeding grounds. In Jepara Regency, Central Java, Indonesia, these ecosystems are threatened by human activities and natural disturbances. This study aimed to assess the biodiversity of reef fish in relation to coral health degradation. Researchers used the Line Intercept Transect (LIT) and Underwater Visual Census (UVC) methods to evaluate fish abundance and coral coverage across three locations with six sampling stations. 936 reef fish individuals, representing 35 species and 14 families, were recorded, with the Pomacentridae family being the most prevalent. The highest coral coverage, categorized as fair, was found at Location II (Blebak Beach) at Stations 3 and 4, with coverage of 27.93% and 25.61%, respectively. This coral coverage was positively correlated with reef fish abundance, with counts of 238 and 246 individuals (average ± SD: 242 ± 5.65). The biodiversity index indicated a dominance index (D) ranging from 0.05 to 0.14 (in the fair category), a high evenness index (E) between 0.75 and 1, and a low dominance index (D) between 0.05 and 0.14. A significant correlation was found between coral coverage and reef fish numbers (P < 0.05, R² = 0.8702), with a linear regression equation of y=6.26+67.71. The findings suggest that the health of coral reef ecosystems significantly affects reef fish populations. Hereafter, the healthiness of this ecosystem will support the scientific core development of Marine Sciences as well as fulfill society's need (economically).

This study aims to analyze the role of stakeholders in the organization of multi-event sports competitions and evaluate the model of rewarding athletes by the central government in Indonesia. Through a qualitative approach with semi-structured interviews, observation, and documentation, this study involved informants from the Indonesian National Olympic Committee and the Ministry of Youth and Sports. The results show that multi-event management is divided into three main stages, namely preparation, execution, and post-event evaluation, with the NOC playing a central role in the coordination and execution of these activities. On the other hand, the rewarding models applied by the government include medal bonuses, appointment as civil servants, and special access to state agencies. This research recommends the development of a more comprehensive and sustainable reward system, including career transition support and post-retirement mentoring. The findings emphasize the importance of collaboration between stakeholders and policy reforms to support the development of national sports.

Medical Physics is a branch of physics application that is developing very rapidly. Therefore, the contextualization of Medical Physics is crucial for future physics teachers. This research aims to implement Student-Teacher-Scientist Partnerships (STSP) in Medical Physics and explore students' perceptions of the learning experience through this program. STSP in this research involved prospective physics teachers as students, lecturers in medical physics courses as teachers, and medical physicists as scientists. The benefits of this research are to provide a learning experience of medical physics directly from experts (medical physicists) as a provision for prospective physics teachers to strengthen their knowledge of medical physics content and how to teach it, and to be a recommendation for learning strategies that support contextual physics learning. Implementing STSP in medical physics courses includes planning, implementation, and evaluation activities for one semester of lectures; lectures by the foremost scientists were held in 7 meetings (1 meeting = 2 x 60 minutes). The planning stage includes activities to equalize perceptions between scientists and related lecturers. The course was primarily student-centred, with case study discussions conducted online via Zoom meetings. The scientists were located in East Java Province, Indonesia, while the teachers and students were in East Kalimantan Province, Indonesia. The evaluation stage was carried out by exploring students' perceptions of the program implementation, the results of which can later be used as a reference for the continuation of the program implementation. Results indicated that STSP activities facilitated easier comprehension of medical physics, increased interest in further study, and highlighted connections between course topics and secondary school curriculum.   

Sports-based tourism can potentially be a tourism product that can provide high economic benefits for a region or even a country. Several types of sports tourism in Sumedang have the potential to be developed, but the local government needs to increase its budget for its development. The purpose of this study is to explore sports tourism, which has the most significant potential for the development of sports tourism, economic quality, regional image and human resources. The method used in this study is qualitative, with using the concepts of Marketability, Sustainability, Participatory, and Disaster Mitigation Management (MSPDM). The results of this study indicate that the marketing indicators of Golf are 100%, paragliding 93%, rafting 80%, and the rest are 50% - 60% each. In the sustainability indicator, paragliding is 96%, golf is 88%, rafting is 68%, and the rest is 48% -56%. In the participant indicator, paragliding 85%, rafting 70%, Golf 55%, and the rest 45% -50%. In the disaster mitigation indicator, paragliding is 100%, rafting is 90%, golf is 70%, and the rest is 40% each. The conclusion of this study shows that 3 potential sports tours were selected with the highest ranking, including Paragliding, Golf and Rafting.
 

Research on place attachment (an individual's emotional bond with their environment) and pro-environmental behavior (attitudes and actions to protect the environment) is important to understand how an individual's emotional bond with their environment can influence pro-environmental behavior, especially for students. This study aims to evaluate the level of place attachment and pro-environmental behavior among junior high school students in Samarinda and examine the correlation between the two variables. This study used a quantitative approach with survey techniques. The research sample consisted of 378 junior high school students in Samarinda who were randomly selected. Data were collected using questionnaires. The results showed that the level of place attachment of junior high school students in Samarinda was 3.75 which was categorized as moderate, while the level of pro-environmental behavior was 3.58 which was also categorized as moderate. A positive but very low correlation existed between place attachment and pro-environmental behavior. This study shows the importance of considering place attachment factors in developing approaches to improve pro-environmental behavior among secondary school students.

Jeruk Manis Village is a village resulting from the expansion of Kembang Kuning Village, after its expansion Jeruk Manis established itself with new branding as a tourist village that is already known for its natural beauty and green rice fields that refresh the eyes. In its efforts to build a tourist village that promises visitors, Jeruk Manis has not provided adequate facilities such as the lack of tourist information for visitors, as well as inadequate changing rooms in several tourist attractions. Therefore, the purpose of KKN PMD University of Mataram for the July-August 2024 period is to optimize tourism in Jeruk Manis Village through making Tourist Information and improving Changing Room facilities. The implementation method used is field survey, location planning, design or design, and program implementation (production and promotion). The results obtained from the making of Tourist Information and Changing Room improvements have a stronger impact on the progress of the branding of the Jeruk Manis Tourism Village, with Tourist Information being a reference for foreign visitors when visiting Jeruk Manis Village. In addition, the placement of the Changing Room made of bamboo which adds to the attractiveness also ensures the comfort of visitors.
