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.

The research instrument utilized the matching method, in which students were required to match pictures with the corresponding vocabulary items. The study was conducted at SMA YPPK St. Thomas Wamena, selecting the seventh-grade students as the population for the 2025/2026 academic year. The researcher applied a cluster sampling technique and selected 30 students as the research sample. Pre- and post-tests were given in order to gather data. Before and after the treatment, students' initial vocabulary mastery was measured with a pre-test, and their performance was evaluated with a post-test. The independent variable in this study was the use of posters, whereas the dependent variable was students’ vocabulary achievement. The findings of the data analysis of the students' vocabulary knowledge in the pre- and post-tests revealed that the t-test value was 17.40 and the t-table value was 2.045. Students' vocabulary competence improved significantly, as evidenced by the t-test value being greater than the t-table value (17.40 > 2.045). This result implies that the pre- and post-test results varied significantly.
