Abstract

Several compounds that can boost immune activity (immunostimulatory) include vitamin E, curcumin, flavonoids, and vitamin C. In this study, ascorbic acid or vitamin C, was used as one method to enhance the immune system. This study aims to determine the immunostimulatory effect of vitamin C on the phagocytosis activity of macrophages in mice induced by Staphylococcus aureus. The mice were divided into two groups: the control group, which received 0.3 ml of distilled water orally, and the treatment group, which received 0.036 mg/g BW of vitamin C orally for 14 days. On the 15th day, each mouse was intraperitoneally induced with 0.5 mL of Staphylococcus aureus bacterial suspension and left for two hours. The phagocytic activity value represents the percentage of active macrophage cells among all macrophages observed. The result showed that the value of % phagocytic activity in the control group was 21.43% ± 7.92, whereas the % phagocytic activity in the treatment group was 48.31% ± 22.27. The group of mice given vitamin C 0.036 mg/g BW orally showed increased phagocytic activity compared to the control group mice. This shows that vitamin C has potential as an immunostimulator.

Abstract

The research aims to determine the species richness, diversity and distribution of mangrove populations in forest areas, which is one of the parameters of forest health in the Passo Village’s mangrove forest. It was conducted from July to August 2023 on Ambon Island using the Forest Health Monitoring Field Methods Guide. The research covered 2 hectares of mangrove forest with 3 clusters of 12 observation plots. It was found that seven species of mangroves were found in the area, namely Sonneratia alba,  Rhizophorastylosa, Avicennia marina, Aegiceras corniculatum, Bruguiera gymnorrhyza and Bruguiera parviflora. Cluster 1 had 260 trees. Cluster 2 had 321 trees, and Cluster 3 had 193 trees. The highest value of mangrove species richness was at the sapling level of 1,003. Meanwhile, the species diversity was classified as low at only 0.701 at the seedling level. The highest density of the Sonneratia alba species was 4,290, the species dominance of the Sonneratia alba was 22,240, and the highest importance index occupied by the Sonneratia alba was 160.95. Considering the low level of mangrove forest biodiversity on Ambon Island, rehabilitation and reforestation efforts are needed to maintain the quality and health of the ecosystem, especially in facing the impact of climate change on small islands.

Abstract

This study examines the implementation of the traditional Balinese philosophy Tri Hita Karana within the modern corporate work culture of Medi Group, a locally owned business in Bali. Employing a qualitative descriptive approach, this research explores how Tri Hita Karana, which emphasizes harmonious relationships between humans and God (Parahyangan), among humans (Pawongan), and between humans and nature (Palemahan), can be integrated into modern organizational practices. Data were collected through in-depth interviews with key informants, including the CEO and Chief Human Officer of Medi Group, supported by observations and document analysis. Using Edgar Schein’s Organizational Culture Theory, the study analyzes the cultural layers of the company, specifically through its core corporate values known as "GREAT" (Grateful, Respectful, Empower, Abundance, Trust). The findings reveal that Tri Hita Karana principles have been effectively incorporated into Medi Group’s organizational culture, influencing company values, employee behavior, internal regulations, and visual symbols. This integration demonstrates that traditional philosophies can coexist with modern business practices, fostering both cultural preservation and sustainable corporate development. The study provides practical implications for other companies in Bali to adopt local wisdom in their corporate governance to enhance social and environmental harmony.

Abstract

This study aims to analyze the structural behavior of Modified T-Stub steel connections under cyclic loading, with the expectation that the results can be applied to steel construction in Indonesia, particularly for structures requiring high seismic performance. In this research, conventional 4ES and Double T-Connections were modified into Modified T-Stub configurations to improve their deformation capacity, strength, and energy dissipation performance. Experimental cyclic loading tests were conducted to evaluate the structural response of the modified connections, focusing on parameters such as strength, stiffness degradation, and drift capacity. Two test specimens were used, namely WF 450×200×9×14 and WF 500×200×10×16, which represent commonly used steel profiles in Indonesian construction practice. Numerical simulations were also performed to support and validate the experimental results. The test results indicate that both specimens exhibited stable hysteretic behavior and satisfactory performance under repeated cyclic loading. The numerical analysis showed that the connections were able to achieve drift ratios of up to 5% radian, while the experimental tests demonstrated drift capacities of approximately 4% radian without significant strength degradation or premature failure. These findings demonstrate that the Modified T-Stub connections meet the performance requirements for certified Special Moment Connections (SMC). This study provides valuable insights into the development of high-performance steel connection systems and contributes to enhancing the safety, efficiency, and structural quality of steel buildings in seismic regions of Indonesia.

Abstract

Occupational safety and health are crucial aspects in the implementation of construction projects, especially large-scale projects such as the construction of the Workshop Building in Cikarang. Workplace accidents that still frequently occur on-site highlight the importance of evaluating the implementation of the Occupational Safety and Health Management System (OSHMS). This study aims to measure the level of OSHMS implementation, identify the barriers to its implementation, and evaluate the strategies used to overcome these barriers. The method used in this study is descriptive evaluative with a quantitative approach, where data was collected through the distribution of questionnaires to 80 respondents consisting of workers and project management teams. The research instruments were tested using validity and reliability tests, and the results were analyzed using mean calculations and the Relative Importance Index (RII). Data was processed using SPSS software. The research results indicate that the level of SMK3 implementation is in the “Very Good” category, with the highest average score of 4.7 and an RSI of 0.94 on the indicator of understanding and implementation of safety procedures. The obstacles faced were categorized as “Less Hindering,” with the lowest average score of 1.89 and an RSI of 0.38 related to management commitment to SMK3. Meanwhile, strengthening strategies such as safety briefings and SOP evaluations were categorized as “Very Effective,” with the highest average score of 4.63 and an IKR of 0.925. The conclusion of this study is that the implementation of SMK3 in this project has been optimal, with minimal obstacles and effective control strategies
