Indonesia is a tropical country, which gets a lot of sunshine every year. Harvesting energy from solar heat is an alternative solution to obtain renewable and environmentally friendly electrical energy. The purpose of this research is to design and test the temperature and flow of the working fluid of a solar collector for energy harvesting. The method used is true experiment research by making a solar collector prototype. Measurement of the temperature and pressure of the working fluid is carried out by varying the power of the heating lamp as a substitute for sunlight in the test. The experimental results show that the greater the heat energy received by the solar collector, the higher the temperature of the working fluid and the resulting pressure during the same test. The highest temperature recorded for the liquid coming out of the solar collector reaches 63.6 oC with a maximum pressure difference of 19.6 Pascals. The results of this test will be followed by testing the flow rate of the working fluid to determine the power potential of the working fluid for harvesting energy. Highlights: Efficiency Enhancement: Optimizing solar collector design for increased heat energy absorption and efficient energy conversion. Temperature-Pressure Correlation: Investigating the relationship between heat energy, working fluid temperature, and pressure for better energy yield. Flow Rate Analysis: Assessing working fluid flow to gauge energy potential and inform effective energy harvesting strategies. Keywords: solar collector, temperature, fluid pressure, energy harvesting

Musculoskeletal disorders (MSDs) are prevalent concerns among the elderly, particularly in occupations involving prolonged repetitive activities such as fishing and farming. This observational cross-sectional study aimed to identify and assess MSD complaints among active elderly fishermen and farmers in rural communities. A total of 50 participants aged 60-65 were surveyed using the Nordic Body Map (NBM) questionnaire to analyze changes in the distribution and severity of MSDs. Results indicated that 70% of respondents were in the 60-65 age group, predominantly male (76%), with females accounting for 24% (12 individuals). The analysis revealed a substantial prevalence of severe MSD complaints (46%), primarily manifested as lower back pain (52%). These findings highlight the significant burden of MSDs among elderly agricultural workers, emphasizing the need for targeted interventions and preventive strategies to enhance their well-being and quality of life.

The Selagan Jaya River Estuary frequently undergoes shape changes, prompting this study to unravel the influence of currents and tides on its morphological evolution. Field measurements encompassing current and tidal data, supplemented by secondary tidal data from TMD and estuary morphology data from USGS, were employed. Findings reveal a mixed semidiurnal tide with a Formzhal value of 0.491 for the Selagan Jaya Estuary. The lowest ebb elevation stands at 0.0117 m, contrasting with the highest flood elevation of 0.6046 m. Flood current velocities range from 0.193 to 1 m/s, while ebb currents span 0.127 to 0.307 m/s. Validation between field and TMD tidal data attains a 98.44% accuracy. Importantly, currents and tides distinctly shape the Selagan Jaya River Estuary; during flood tides, sediment-laden currents ingress, while ebb tides with slower currents hinder sediment egress, underscoring their profound morphological impact. Highlight: Estuarine Morphological Dynamics: Investigates the dynamic nature of the Selagan Jaya River Estuary's shape changes and its underlying processes. Tidal and Current Influence: Unravels the intricate interplay between currents and tides, revealing their significant role in shaping the estuarine morphology.

The Western Sumatra Waters experience significant influence from mass differentials between the Indian Ocean and Pacific Ocean, resulting in intricate oceanic circulations. This study focuses on geostrophic currents, vital for global climate dynamics, aiming to analyze their distribution and extreme occurrences. Using monthly-averaged geostrophic current data from 2018 to 2020 obtained via Altimetry Satellite imagery, the analysis reveals variations in velocity, magnitude, and direction across months. A notable peak velocity of 1.2 m/s in May 2020 and a minimum velocity of 0.1 m/s in June 2020 are highlighted, offering insights into their complex dynamics and implications for the region's oceanic processes and global climate dynamics. Highlight: Oceanic Interplay: The study highlights the profound influence of mass differentials between the Indian Ocean and Pacific Ocean on intricate oceanic circulations in the Western Sumatra Waters. Geostrophic Current Dynamics: Examining geostrophic currents as a crucial element of global climate dynamics, the research reveals significant variations in velocity, magnitude, and direction across different months. Peak and Minimum Instances: Notable instances are identified, such as the May 2020 peak with currents dispersing from west to southeast, and the June 2020 minimum characterized by erratic directional behavior, shedding light on specific temporal patterns.
