Abstract

Saham merupakan bentuk investasi di pasar modal yang mampu menarik perhatian investor. Harga saham bersifat fluktuatif sehingga terjadi peningkatan dan penurunan harga. Model stokastik yang seringkali digunakan untuk memprediksi harga saham yaitu FTS-Markov Chain dan Geometric Brownian Motion (GBM). Penelitian ini bertujuan membandingkan kinerja dari model FTS-Markov Chain dan GBM dalam memprediksi harga saham. Kinerja kedua model prediksi dievaluasi dengan cara membandingkan nilai MAPE. Data yang digunakan adalah data harian harga penutupan saham BBRI sejak 01 November 2023 hingga 31 Oktober 2024 sebanyak 239 data. Data penelitian terbagi atas data training dan testing dengan proporsi masing-masing sebesar 80:20. Berdasarkan hasil penelitian, nilai MAPE yang diperoleh berdasarkan model FTS-Markov Chain dan GBM secara berturut-turut yaitu 1,19% dan 7,53%. Model FTS-Markov Chain menghasilkan nilai MAPE yang lebih kecil, sehingga dapat dikatakan bahwa hasil prediksi menggunakan FTS-Markov Chain lebih akurat dibandingkan GBM. Secara keseluruhan model FTS-Markov Chain mampu menangkap pola prediksi dan fluktuasi harga saham. Oleh sebab itu, model yang memiliki kinerja lebih baik dalam memprediksi harga saham BBRI adalah FTS-Markov Chain. Kata kunci: fuzzy time series Markov chain, harga saham, model GBM, prediksi

Abstract

Learning media plays a crucial role in helping teachers deliver material effectively, particularly at the elementary school level, which demands an active, enjoyable learning environment that is appropriate to students' developmental stages. However, many elementary schools still employ conventional learning methods that rely on lectures and simple media, leading to student boredom and a lack of motivation. This study aims to develop SmartEdu Games as a prototype for educational game-based learning media designed to increase student interest and engagement in thematic learning. The study employed the Research and Development (R&D) method with the ASSURE design model, but was only implemented up to the prototype development stage because the study did not involve expert validation or student trials. The prototype product was designed to include learning materials, interactive activities, and mini-games as practice tools. The results of the study indicate that SmartEdu Games was successfully developed as an initial prototype that has the potential to be used as an interactive learning medium at the elementary school level. This prototype can be an alternative digital media that supports independent learning and teacher mentoring, and has the potential for further development in the validation and trial stages

Abstract

This study aims to determine the effect of using digital mind mapping on students' reading comprehension ability in recount texts. This study uses a pre-experimental method with one group pre-test post-test. The research sample consisted of eighth-grade students at SMPN 2 Rambah Samo in the 2025/2026 academic year. The research instrument was a multiple-choice test consisting of 32 questions that had been tested for validity and reliability (Cronbach's Alpha = 0.974). The data were analyzed using normality tests, paired sample t-tests, and N-Gain. The results showed an increase in students' reading comprehension skills after using digital mind maps. The average pre-test score was 58.93, while the post-test score was 67.36. The Sig. value (two tails) was 0.000 < 0.05, so Ha was accepted. Thus, digital mind maps have a significant effect on students' reading comprehension ability.
