Bajakah tampala (Spatholobus littoralis Hassk.) is a medicinal plant that is traditionally used by the Dayak people to overcome various diseases, including indigestion such as diarrhea and dysentery. This plant is known to contain secondary metabolites, including flavonoids, tannins, saponins, alkaloids, and phenolics, which have the potential to have antibacterial activity. This study aims to evaluate the antibacterial activity of pulp extract of patchy bajakah with n-hexane solvent against Escherichia coli ATCC 25922. The extract was obtained through the maceration method and tested using the well diffusion method at concentrations of 10%, 20%, and 30%. The results showed a relatively low yield of the extract (0.10–0.14%) with a reddish-orange color. The inhibition zones formed ranged from 4.28–5.55 mm with significant differences between concentrations (p = 0.000), but the antibacterial activity was relatively low. These findings indicate that the active compounds of the patch stalk are likely to be more polar or semi-polar, so they are less optimally extracted using the nonpolar solvent n-hexane. Therefore, further research with different solvent variations, particularly those that are polar, is urgently needed to uncover the greater antibacterial potential of these plants.

Enteric bacterial infectious diseases such as Escherichia coli are still a serious health problem in many countries, mainly due to the increasing cases of antibiotic resistance that cause the effectiveness of conventional therapies to decline. This condition encourages the search for safer and more effective natural alternatives, one of which is propolis produced by the Trigona sp. bee Trigona sp. Propolis is known to contain a variety of bioactive compounds, including flavonoids and phenolic acid, which act as antimicrobials. This study aims to test the antibacterial activity of propolis extract against E. coli by the sumpray diffusion method. The results of the study showed that there was an inhibition zone that varied according to the concentration of the extract. At a concentration of 10%, an average inhibition zone of 19.85 mm (strong category), a 20% concentration of 22.35 mm (very strong), and a concentration of 30% reaches 26.62 mm (very strong). In comparison, the positive control of ciprofloxacin produced 21.25 mm of resistance, while the negative control (DMSO) showed no activity. ANOVA analysis confirmed significant differences between treatments (p < 0.05). These findings confirm that propolis extract has the potential to be developed as an effective natural antimicrobial agent.

This community service activity aimed to control the population of Aedes aegypti mosquitoes, which are the main vector of Dengue Hemorrhagic Fever (DHF), through the making and utilization of ovitraps in Sawa Village, Sawa District, North Konawe Regency. The methods applied in this program included field observation and door-to-door socialization to the community regarding the function, benefits, and procedure of making ovitraps. The socialization was designed to provide practical knowledge and raise awareness among residents about the importance of preventing mosquito breeding as part of DHF control efforts. A total of 30 households were involved as direct participants in this activity, and 30 ovitrap units were successfully made and distributed evenly to each household. The results showed that the community responded enthusiastically and expressed interest in adopting the ovitraps as a preventive measure. In addition, participants reported gaining new understanding about their active role in maintaining environmental health and reducing the risk of DHF transmission. The involvement of the community not only ensured that the ovitraps were effectively utilized, but also encouraged sustainable behavior in mosquito control practices. Overall, this program demonstrated that simple, low-cost, and community-based interventions such as ovitraps, combined with education and awareness campaigns, can contribute significantly to reducing the breeding sites of Aedes aegypti mosquitoes and lowering the potential spread of DHF in endemic areas.

Pain is one of the main complaints experienced by postoperative patients, including those undergoing laminectomy, which can interfere with comfort, hinder mobility, and slow the healing process. Non-pharmacological nursing interventions such as relaxation techniques have become important alternatives for reducing pain holistically. This study aims to evaluate the effectiveness of the finger-holding relaxation technique in reducing pain in postoperative laminectomy patients. The study used a descriptive case study design involving a patient named Mrs. S in the Amarilis Ward of Prof. Dr. Margono Soekarjo Regional Hospital, Purwokerto. The intervention was carried out for three consecutive days, twice a day, with each session lasting 15 minutes. The results showed a marked decrease in pain score from a scale of 7 (severe pain) on the first day to 1 (mild pain) on the fourth day, accompanied by gradual improvement in physical mobility, absence of surgical wound infection, and better discharge readiness. This technique also had a positive impact on the patient’s emotional comfort. Therefore, the finger-holding relaxation technique is proven to be a simple yet effective intervention in supporting the holistic recovery of postoperative laminectomy patients.

Enhancing the efficiency of renewable energy on ships is crucial for reducing dependency on fossil fuels. This research employs the Research and Development (R&D) method, aiming to design and implement a solar panel optimization system for battery charging, with a focus on increasing power efficiency and providing real-time performance monitoring. The system is designed using Maximum Power Point Tracking (MPPT) technology to maximize the solar panel's power output. A 200Wp solar panel with dimensions of 1290 x 760 x 30 mm was utilized. Static testing results show that the deployed sensors possess a high degree of accuracy, with an average error of 0.71% for the temperature sensor and only 1.81% for the light sensor used to monitor environmental conditions. Dynamic and system integration tests prove that the MPPT implementation significantly increases power output efficiency by 30.83% compared to a system without MPPT. Furthermore, the system with MPPT charges the battery approximately 27% faster. Additionally, the developed Modbus protocol-based monitoring system enables comprehensive and remote monitoring of key parameters such as voltage, current, temperature, and light intensity via a cloud database. Data communication reliability tests confirmed the system's capability to transmit entire data packets to a Google Sheets database at a periodic interval of 15 seconds without failure. Based on these results, the developed solar panel optimization system is feasible for implementation in maritime environments to enhance the utilization efficiency of renewable energy and the operational reliability of onboard systems.
