Abstract

This thesis research was carried out at the Sukabumi City Disporapar. The purpose of this writing is to determine the effect of budget planning and budget evaluation on performance accountability in the Sukabumi City Disporapar. The variables used are Budget Planning and Budget Evaluation as Independent Variables and Performance Accountability as Dependent Variables. The research method used is Quantitative with associative type. The scale of measurement used is the ordinal scale. The population used is the employees associated with the planning and finance section of the Sukabumi City Disporapar, with a purposive sampling technique. the number of samples is 40 employees. the types of data used are primary and secondary data. The data collected was analyzed using validity and reliability tests, data quality tests, classic assumption tests, hypothesis testing, namely the t test, F test and the coefficient of determination test. The results showed that in the independent variable validity test, 14 statements were declared valid, and the dependent variable contained 6 valid statements. the results of the reliability test show that the independent and dependent variable instruments are reliable. the results of testing the hypothesis show that budget planning and budget evaluation have a significant positive effect on performance accountability. and the results of the test of the coefficient of determination of the budget planning and budget evaluation variables are able to explain the performance accountability variable. The results showed that of the budget planning and budget evaluation had a significant positive impact on performance accountability at the Sukabumi City Disporapar. based on the results of the calculation of the coefficient of determination, it is obtained that the magnitude of the impact of budget planning and budget evaluation on performance accountability is 72.2%. while the remaining 27.8% is influenced by other factors not examined.

Abstract

Gold mining exploration causes extensive land degradation characterized by highly acidic pH (4.0–5.0), topsoil loss, and very low organic matter content, requiring sustainable revegetation strategies to restore ecosystem and land productivity. This research identifies local, adaptive plant species for the revegetation of former gold-mining exploration land in West Sumbawa, develops an integrated agroforestry-based revegetation system, evaluates revegetation success using a comprehensive scoring system, and designs optimal planting geometry based on topography. The method employs systematic sampling over 6.74 hectares, stratified by planting year (2021–2023), and primary data collection through vegetation inventory, plant growth measurement, health assessment, and analysis using descriptive statistics, ANOVA, Pearson correlation, and the Regulation of the Minister of Forestry P.60/2009 scoring system. Results demonstrate the gamal–mahogany agroforestry system achieved gamal survival rate of 96.3% and Mahogany 92.3%, height growth of gamal 2.5–3.0 m/year and Mahogany 3.1–3.5 m/year, increased C-organic by 105%, N-total by 167%, pH by 0.65, and P-available by 156%, with a success score of 21.8/25 in the "Highly Successful" category according to regulations.
