research is to develop a mathematical model capable of converting analog values from the Analog-to-Digital Converter (ADC) into a numerical representation that reflects the actual water turbidity level in Nephelometric Turbidity Units (NTU). The calibration process was performed using a standard Hanna Turbidity Meter with water samples ranging from 0.56 NTU to 500 NTU. Measurement results demonstrated a strong linear relationship between the ADC value (495–686) and NTU, with an average system accuracy level above 90%. Comparison of sensor measurements with the standard instrument showed an error margin below 5%, confirming the reliability of the linear regression model in compensating for optical sensor nonlinearities.

-analytical stage, including the type of blood collection tube used. Two commonly used tubes are the plain vacutainer and the clot activator vacutainer, each with different additives that may affect blood clotting time and test results. This study aimed to determine the differences in uric acid test results and clotting time using these two types of tubes. A simple experimental method with a comparative design was conducted at Klinik Pratama Rawat Jalan Mambal Medical Care from March to April 2025. The sample consisted of 15 respondents, each undergoing two blood draws using both tube types. The results showed that the average clotting time for the clot activator tube was 9.27 minutes, while for the plain tube it was 24.67 minutes. The average uric acid level measured using the clot activator tube was 5.27 mg/dL, compared to 5.14 mg/dL using the plain tube. Statistical analysis using the Wilcoxon signed-rank test indicated a significant difference in clotting time but no significant difference in uric acid levels (p > 0.05). It can be concluded that the use of clot activator vacutainer tubes accelerates the blood clotting process but does not significantly affect uric acid levels compared to plain tubes.

This study analyzes the impact of PT. Jasa Raharja’s insurance on inpatient expenses for traffic accident victims in Pekanbaru City. The research applies a quantitative approach with descriptive analysis and simple regression. Data came from 120 respondents, consisting of victims and their families who received insurance benefits. The findings show that PT. Jasa Raharja’s insurance claims cover an average of 67% of total hospitalization costs, significantly reducing the victims’ financial burden. However, the coverage ceiling remains limited and does not fully meet medical expenses. This study concludes that PT. Jasa Raharja makes a substantial contribution to financing accident-related hospitalization, although increasing the claim ceiling would better align with current hospital costs.
