Abstract

In the learning process, students must be able to regulate themselves. This is an effort to improve the quality of student learning, especially their learning achievement. The purpose of this study is to empirically analyze the characteristics of self-regulation skills in learning mathematics. The analysis was carried out by utilizing Item Response Theory (IRT) with a Partial Credit Model (PCM). This study is a descriptive quantitative study with the subjects of the study being 123 students of grade 10 of Senior High Schools in Yogyakarta. Data collection was carried out using a questionnaire that had been developed and its item characteristics were analyzed using IRT. The independent learning scale questionnaire in mathematics consists of 16 statement items and measures 5 aspects. Based on all the questions that are feasible to be analyzed using the PCM model, it is known that there are 5 aspects that fit, namely (1) self-confidence, (2) discipline in learning, (3) active in learning, (4) responsibility, and (5) motivation in learning. This instrument can be used to measure students' self-regulation skills in learning mathematics based on their ability level.

Abstract

Penelitian ini bertujuan untuk menentukan rute terpendek dari Stasiun Lempuyangan ke UIN Sunan Kalijaga Yogyakarta menggunakan algoritma Dijkstra. Data berupa jarak aktual antar lokasi diambil dari Google Maps dan direpresentasikan dalam bentuk graf berbobot, dengan simpul sebagai lokasi dan sisi sebagai jarak antar lokasi. Algoritma Dijkstra bekerja dengan mencari jarak terpendek dari simpul awal ke simpul lainnya secara iteratif hingga mencapai simpul tujuan. Proses perhitungan dilakukan dengan bantuan aplikasi berbasis VB.Net. Hasil penelitian menunjukkan bahwa rute terpendek dari Stasiun Lempuyangan ke UIN Sunan Kalijaga adalah melalui A → B → D → E → H → K dengan bobot total 3,45. Implementasi algoritma Dijkstra terbukti efisien dan akurat dalam menentukan jalur terpendek, sehingga dapat menjadi solusi optimal untuk sistem navigasi dan pemetaan
