Abstract

Measuring land plots is the process of determining the location of the boundaries of land plots, which is part of the process of making land title certificates. The number of land plots in the Langsa City Land Office during December 2023 to November 2024 shows a fluctuating pattern. The aim of this analysis is to find out The results of forecasting the number of land plots at the Langsa City Land Office using the Adams Bashforth Moulton method. The data used is land plot measurement data with the type of data being secondary data obtained from the City Land Office Langsa. The type of analysis used is quantitative analysis using the Adams Bashforth Moulton method. The Adams-Bashforth-Moulton (ABM) method is used to determine the forecasting results on the number of measurements of land plots at the Langsa City Land Office. This method starts with an initial solution using fourth order Runge-Kutta, then substituted into the Adams-Bashforth predictor equation and corrected with the Adams-Moulton corrector equation. The iteration is stopped if the relative error is less than 5×10⁻⁷ after 15 iterations at the interval [0,15]. As a result, the number of land plot measurements in Langsa City increases every year, with 62 plots in December 2024, 63 plots in January 2025, 65 plots in February 2025, and 66 plots in March 2025.

Abstract

This study aims to examine changes in the number of companies paying groundwater tax in Labuhanbatu Selatan Regency in 2023 and 2024. Groundwater tax serves as one of the revenue sources for local governments and supports development as well as water resource management. The data were obtained from the Regional Revenue Agency of Labuhanbatu Selatan and analyzed using a non-parametric statistical method, namely the sign test, to evaluate the paired data from the two periods. The results indicate an increase in the number of companies paying the tax in 2024 compared to 2023. The significance value of 0,006, which is below the 0,05 threshold, confirms that the increase is statistically significant. Therefore, it can be concluded that company compliance with groundwater tax payments improved in 2024. This finding suggests the need for continuous monitoring and guidance from the local government to maintain and strengthen this positive trend.
