Abstract

Budget classification plays a crucial role in planning, management, and budgeting, from implementation to accountability. We create budgets by considering various types of expenditures and funding sources. Each type of expenditure, such as employee salaries, goods, capital, grants, social assistance, subsidies, interest, and non-tax revenue (PNBP) or public service agencies (BLU), has its own set of rules and methods for tracking money. This study aims to demonstrate how budget classification, based on expenditure types and funding sources, is applied in the implementation of the Revenue Budget. This study aims to assess the classification performance of two models, namely the Random Forest Classifier (RFC) and Support Vector Machine (SVM), based on historical data and evaluate the performance of each model. Tests show that the Random Forest model consistently outperforms the SVM model for each data proportion, with a ratio of 90:10 to 60:40. The Random Forest model achieved its best performance at the 80:20 data split, with an accuracy score of 94 percent, a precision score of 94 percent, a recall score of 94 percent, and an F1 score of 87 percent. The average accuracy score of the SVM test results was 80 percent.

Abstract

Penelitian ini memodelkan kecepatan angin harian pada jalur penyeberangan Gresik--Bawean periode Desember 2020 hingga November 2023 menggunakan Jaringan Saraf Tiruan (JST) dengan algoritma backpropagation. Data yang digunakan meliputi kecepatan angin, tinggi gelombang rata-rata, panjang gelombang, periode gelombang, dan tinggi maksimum gelombang. Model dievaluasi dengan skema \textit{walk-forward validation} dan dibandingkan dengan model baseline seperti \textit{persistence} dan SARIMA. Kinerja diukur menggunakan metrik MAE, RMSE, sMAPE, dan MASE dengan interval kepercayaan bootstrap, serta pengujian signifikansi menggunakan uji Diebold--Mariano. Hasil menunjukkan bahwa arsitektur terbaik JST (5--3--2--1) mampu menurunkan RMSE secara signifikan dibandingkan baseline (p $
