The implementation of health information systems such as SIMKES (Sistem Informasi Manajemen Kesehatan) plays a crucial role in enhancing administrative efficiency and service delivery in primary healthcare centers. However, user satisfaction remains a key indicator of system effectiveness, especially in outpatient service units. This study aims to evaluate the satisfaction level of health personnel toward the implementation of SIMKES at the outpatient unit of Teguhan Health Center, Ngawi, Indonesia. Employing a descriptive quantitative method, this research involved a census of 17 respondents using a validated questionnaire based on the End-User Computing Satisfaction (EUCS) model, which comprises five dimensions: content, accuracy, format, ease of use, and timeliness. The data were analyzed using frequency distribution and mean scoring to categorize satisfaction levels. Results showed that the overall satisfaction score was 73.58, indicating that users were generally satisfied with the system. All five EUCS dimensions were categorized as satisfactory, with the highest rating in the format dimension and the lowest in timeliness. Despite the overall positive assessment, users reported issues related to system speed, technical bugs, and limited guidance for system navigation. The findings suggest that while SIMKES supports outpatient service delivery effectively, improvements are needed in system responsiveness and user support to enhance satisfaction and usability. This study contributes to the ongoing evaluation and development of health information systems in resource-limited primary care settings.

This study evaluates the implementation of Behavior Based Safety (BBS) in improving occupational safety compliance at PT Wichindo Pratama, a heavy equipment manufacturing company with high work risks. The topic was chosen due to frequent violations of safety procedures, such as the improper use of Personal Protective Equipment (PPE) and neglect of Standard Operating Procedures (SOP), which increase the risk of accidents. A qualitative method was used through direct observation, in-depth interviews with 12 shift workers, and field assessments of safety facilities. The findings show that although the company has an Occupational Health and Safety (OHS) management system, non-compliance still occurs. Issues include incomplete PPE usage, disorganized work tools, and unsafe rest habits. Observations revealed potential hazards such as physical (noise), chemical (oil exposure), ergonomic (awkward postures), mechanical (machine use without full PPE), biological, and psychological risks (stress from shift work). BBS is seen as a strategy to connect existing OHS policies with safe work behavior by focusing on mindset and daily habits. The implementation of BBS is expected to reduce accidents and support the creation of a safer, more sustainable workplace.

This study aims to examine the potential and challenges of utilizing Solar Power Plants (PLTS) in Medan City, which is geographically located near the equator and receives high exposure to sunlight throughout the year. The method used is a literature review with a narrative review approach that analyzes secondary data from various journals and relevant scientific articles. The results of the study show that Medan City has an average annual horizontal global solar radiation intensity of 463.61 W/m², with the potential for electrical power that can be generated from rooftop solar panels reaching 748.57 MW (monocrystalline), 598.85 MW (polycrystalline), and 299.43 MW (thin film). This potential is comparable to the capacity of large-scale power plants. The use of PLTS contributes to reducing carbon emissions, increasing energy security, creating jobs, and developing the local economy. However, challenges such as high installation costs, limited suitability of roof structures, and low public awareness are still major obstacles in the implementation of this technology. Therefore, synergy is needed between government policies, public education, and technological innovation to optimize the use of solar energy in urban areas such as Medan.

Abstrak:
This study aims to compare two main theories in modern cosmology, namely the Big Bang Theory and the Steady State Theory, using a descriptive cosmographic approach. This study is motivated by the lack of deep understanding as well as the limited Indonesian literature discussing the fundamental differences between the two theories. By employing a qualitative method through literature review, this research examines the characteristics, advantages, and limitations of each theory based on the latest scientific evidence and cosmographic perspectives. The analysis results show that the Big Bang Theory has strong support from observational evidence, such as cosmic microwave background radiation (CMB), galaxy redshift, and the distribution of light elements, which reinforces the narrative of the expansion and evolution of the universe. In contrast, the Steady State Theory is considered less relevant due to the absence of observational evidence for the creation of new matter and its inability to explain structure and the dynamics of the universe that are currently observed.

This study uses a qualitative method to describe the infestation of Oryctes rhinoceros beetles in oil palm plantations and its impact on crop productivity. This pest poses a major threat to oil palm cultivation due to its ability to damage the growing points of both young and mature plants, resulting in a significant decline in yield. The study was conducted through field observations and in-depth interviews with farmers and field technicians at an oil palm plantation in Sumatra. The findings reveal that Oryctes infestations are more prevalent in plantations with poor sanitation and limited implementation of regular biological control systems. Farmers predominantly rely on mechanical and chemical control methods, which have proven to be less effective due to the lack of coordinated and sustainable application. Therefore, an ecologically-based integrated pest management strategy is needed, combining biological control, cultural practices, and farmer education to effectively suppress pest populations and ensure the sustainability of oil palm production.
