Abstract

The purpose of this study is to get an optimal forecasting model of CPI data in Yogyakarta using neuralnetwork models that is built with the involvement of the intervention effect. This case happens because of the policyof rising fuel prices. CPI education, recreation, and sport have a pattern like a step function, so that the exact RNNmodels are the models with the input as the truncated polynomial spline regression models. The results of modelpredictions both training and testing data showed high accuracy. Key words: neural network, intervention, CPI

Abstract

Student cognitive diversity can be a barrier to enhancing critical thinking and science process skills. The TaRL-based DSI model addresses this by facilitating learning for students at different cognitive levels. This research aims to determine the effect of the Differentiated Science Inquiry (DSI) model based on the Teaching at the Right Level (TaRL) approach on eighth-grade junior high school students’ critical thinking and science process skills in the context of vibration and wave concepts. A non-equivalent control group design was used to address varied learning needs, with 55 students purposively selected for experimental and control groups. Data were collected using essay-based critical thinking tests and multiple-choice science process skills assessments. The DSI model applied four inquiry levels: Demonstrated Inquiry, Structured Inquiry, Guided Inquiry, and Self-Directed Inquiry based on students’ initial abilities. Data were analyzed using descriptive and inferential methods. The average critical thinking skills in the experimental group after treatment were 13.04, and in the control group were 10.1. The average science process skills in the experimental group were 19.77, and in the control group were 18. The research results confirm that the TaRL-based DSI model significantly enhances students’ critical thinking and science process skills at a significance level of α = 0.05. This research is expected to help educators implement the DSI model to accommodate diverse learning needs and enhance crucial skills in science education.

Abstract

Payment delinquency of SPP is a commonly occurring issue in school. It affects the salary of teachers and staffs alongside school’s various development program. The study aims to classify payment delinquencies using Naïve Bayes and Support Vector Machine. Research methode is Cross-Industry Standard Process for Data Mining (CRISP-DM). Method testing was carried out with 5 trials. Based on the test results, the average performance of Naïve Bayes is accuracy (62,88%), precision (65,27%), recall (77,42%) dan f1-score (70,75%). Meanwhile, the average performance of the Support Vector Machine is accuracy 63,51%), precision (62,25%), recall (94,48%) dan f1-score (75,04%).
