Traditional markets play a central role in the local economic system and the social life of communities, particularly in Medan City. However, the dynamics of urbanization, competition from modern retail, and changes in consumer behavior have posed significant challenges to their sustainability. This study aims to analyze the relationship between the strategic location of traditional markets and their economic performance using a mixed-methods approach and spatial analysis. The research focuses on six traditional markets in Medan City: Petisah Market, Sukaramai Market, Beruang Market, Ikan Lama Market, Sei Sikambing Market, and Pringgan Market. Quantitative data were collected through questionnaires using a Likert scale and analyzed descriptively and correlationally, while qualitative data were gathered through field observations and in-depth interviews to interpret the socio-spatial context of each market. The key variables include accessibility, commodity diversity, and environmental comfort, which are linked to economic performance indicators such as visitor numbers, buyer loyalty, and sales stability. The results show that Petisah, Pringgan, and Ikan Lama Markets scored highest in these variables and demonstrated better economic performance. Correlation analysis identified commodity diversity as the most influential factor on economic performance, followed by environmental quality and accessibility. To strengthen the analysis, a SWOT model was also applied to identify the strengths, weaknesses, opportunities, and threats faced by traditional markets. This analysis reveals that the primary strengths of the markets lie in their location and social interaction, while the main challenges stem from a lack of modern management and pressure from digital markets. This study recommends development strategies based on local advantages, infrastructure modernization, market information digitalization, and cultural promotion as steps to sustainably enhance the competitiveness of traditional markets amid urban spatial changes.

Anemia is a global health problem affecting approximately 30% of adolescents worldwide, with the highest prevalence among women aged 15-49. In Indonesia, data from the Ministry of Health in 2019 showed that the prevalence of anemia in adolescent girls reached 32%, with cases higher than in adolescent boys (27.2% vs. 20.3%). Anemia in adolescent girls negatively impacts growth, increases susceptibility to infection, and affects concentration and academic performance.

These results indicate that consuming pandan leaf pudding is effective in increasing hemoglobin levels in the study group.

Preventing accidents during drilling and well service operations is a constant and primary concern for every company or contractor operating in the upstream business. Accident analyses often identify a number of causative factors and/or anomalies, where equipment-related items play a significant role. This article concentrates on the rig inspection process as a consistent method for detecting equipment-related anomalies before operations commence. These inspections allow necessary repairs to be made in a timely manner, thereby limiting the occurrence of accidents after the rig becomes operational. When thorough and systematic rig inspections are performed, the percentage of accidents where equipment failure is the primary cause remains very low. However, the factor of equipment condition contributing to accidents still persists in a significant number of cases. Drilling rig mast inspection is a crucial component in maintaining the safety and efficiency of drilling operations. This inspection process aims to detect structural anomalies and equipment conditions that could affect rig performance. In this study, we analyze the inspection methods applied to rig masts, including visual inspection, non-destructive testing, and condition monitoring. The results of these inspections are expected to identify potential risks and enable necessary repairs before operations begin. Through the implementation of systematic and standardized inspection procedures, companies can reduce the likelihood of accidents and equipment failures, thereby enhancing workplace safety. This study also discusses the importance of training for inspection personnel to ensure they possess the necessary knowledge and skills to detect potential problems that may arise. Thus, drilling rig mast inspection contributes not only to safety but also to overall operational efficiency.

Tennis elbow, or lateral epicondylitis, is an inflammatory condition of the lateral epicondyle commonly caused by repetitive overuse of the forearm extensor muscles. It is characterized by pain, limited joint range of motion, decreased muscle strength, and reduced functional capacity. Physiotherapy interventions, particularly ultrasound and exercise therapy, have been widely applied to reduce pain and restore functional performance. This study employed a case study design involving a 42-year-old female patient diagnosed with left-sided tennis elbow. The intervention was conducted over four therapy sessions. The modalities consisted of ultrasound, providing thermal and micromassage effects to reduce pain, combined with exercise therapy, including passive stretching to increase soft tissue flexibility and eccentric exercise to improve tendon strength and function. After four sessions, the patient showed significant improvement, including reduced pain during movement and palpation, increased joint range of motion in elbow flexion-extension, forearm pronation-supination, and wrist dorsiflexion-palmarflexion. Muscle strength, particularly in the extensors, pronators, supinators, and wrist dorsiflexors, also improved. Functional activity, measured using the PRTEE scale, demonstrated notable enhancement from mild disability to better functional independence. The combination of ultrasound, passive stretching, and eccentric exercise is effective in reducing pain, enhancing range of motion, strengthening muscles, and improving functional ability in patients with left-sided tennis elbow.

Memory is a vital biological system in the body that plays a role in storing, processing, and recalling information. Over time, due to aging or external factors, memory function may decline. One possible effort to maintain and improve cognitive performance is through the use of bioactive compounds with antioxidant properties. Avocado (Persea americana Mill.) leaves contain flavonoids, which act as antioxidants and possess neuroprotective effects that may enhance cognitive function, including memory. This study aimed to determine the effect of avocado leaf extract on the memory of male mice and to identify the most effective dose in improving cognitive performance. The extract was obtained using the maceration method with 70% ethanol as the solvent. Memory activity was tested on male mice, which were divided into five groups: negative control, positive control, and three treatment groups given avocado leaf extract at doses of 50, 100, and 200 mg/kgBW. The Y-Maze method was employed to assess memory through two parameters: latency time and error numbers. The results demonstrated that avocado leaf extract significantly improved memory in the test animals. Mice induced with 10% ethanol showed an increase in latency time and error numbers, while the groups treated with avocado leaf extract experienced reductions in both parameters. The most effective dose was 200 mg/kgBW, which produced a latency time difference of 19.5 seconds and an error number difference of 3.57. Therefore, avocado leaf extract shows potential as a natural agent to support and enhance cognitive function.

This study aims to analyze the influence of work discipline, job satisfaction, and motivation on the performance of billman employees at PT. PLN Electricity Services ULP Kediri City. Employee performance plays a strategic role in ensuring the company’s service quality and operational sustainability, particularly in the field of billing services which directly impacts customer satisfaction and company revenue. The research employs a quantitative approach with a multiple linear regression method to assess both partial and simultaneous effects of the independent variables. The population of this study consisted of all 33 billman employees of PT. PLN Electricity Services ULP Kediri City, and due to the small size, a saturated sampling technique was used so that the entire population served as respondents. Primary data were collected through questionnaires distributed to all employees and then analyzed statistically. The findings indicate that, partially, work discipline has a negative and insignificant effect on employee performance, suggesting that discipline alone does not guarantee productivity improvement. On the other hand, job satisfaction and motivation both have a positive and significant effect on employee performance, showing that intrinsic and psychological factors contribute more strongly to optimal work outcomes. Furthermore, when tested simultaneously, work discipline, job satisfaction, and motivation collectively exert a positive and significant influence on employee performance. The coefficient of determination (R²) of 0.786 indicates that 78.6% of variations in performance can be explained by the three variables, while the remaining 21.4% is influenced by other factors outside this research model. These findings emphasize the importance of fostering job satisfaction and motivation through supportive management policies to enhance employee contributions and organizational effectiveness.

This study examines the impact of workload and work stress on employee job satisfaction at PT Inhutani I UMI Gresik, a wood-processing company operating under Perum Perhutani. The research employed a quantitative design with an associative (causal) approach to identify the extent to which workload and stress contribute to variations in job satisfaction. Data were collected through questionnaires distributed to 48 employees selected using a simple random sampling method. The analytical process involved validity and reliability testing, classical assumption tests, multiple linear regression, as well as t-tests, F-tests, and the coefficient of determination (R²). The results indicate that workload and work stress, when considered simultaneously, have a significant influence on job satisfaction. However, partial testing revealed that workload did not exert a significant effect, while work stress had a statistically significant negative impact on satisfaction. Regression analysis further demonstrated that work stress emerged as the dominant predictor, accounting for a larger proportion of variance compared to workload, as reflected by the higher beta coefficient and partial determination value. These findings suggest that while workload may serve as a motivator when maintained within reasonable limits, unmanaged stress arising from role ambiguity, conflicting demands, and organizational pressures significantly undermines job satisfaction. The study underscores the importance of stress management strategies within organizations, particularly in high-demand industries such as forestry and wood processing. Practical implications include the need for supportive leadership, effective communication, realistic target-setting, and the implementation of employee assistance programs. By addressing stress more effectively, organizations can enhance employee well-being, foster greater job satisfaction, and ultimately improve overall organizational performance.
