Abstract

Studi peramalan harga beras menengah di Jawa Barat selama ini sebagian besar mengandalkan pendekatan satu model tanpa evaluasi out-of-sample yang sistematis, sehingga kinerja prediktif komparatif dari berbagai model deret waktu yang bersaing dalam kondisi peramalan yang realistis belum diteliti. Penelitian ini mengatasi kesenjangan tersebut dengan membandingkan lima model deret waktu, yaitu Seasonal Naïve, ARIMA (1,1,1), Additive Holt-Winters ETS, SARIMA (0,1,1) (0,1,1,12), dan SARIMA (1,1,1) (1,1,1,12) untuk harga beras medium bulanan di Provinsi Jawa Barat. Data diperoleh dari Pusat Informasi Harga Pangan Strategis Nasional (PIHPS) yang mencakup periode April 2017 hingga November 2025, terdiri dari 104 pengamatan bulanan. Kinerja model dievaluasi menggunakan prosedur jendela yang diperluas selama periode uji 21 bulan (Maret 2024 – November 2025) berdasarkan tiga metrik akurasi: MAE, RMSE, dan MAPE. Hasil menunjukkan bahwa ARIMA (1,1,1) secara konsisten mengungguli semua model pesaing, dengan mencapai MAE sebesar Rp 92,63/kg, RMSE sebesar Rp 169,47/kg, dan MAPE sebesar 0,62%, yang diklasifikasikan sebagai sangat akurat berdasarkan kriteria Lewis (1982). Temuan ini menunjukkan bahwa, dalam periode evaluasi yang ditandai oleh gangguan pasokan akibat El Niño dan perubahan kebijakan HET pemerintah, spesifikasi ARIMA non-musiman mencapai akurasi out-of-sample yang lebih unggul dibandingkan model SARIMA yang memasukkan komponen musiman historis, pola ini sejalan dengan kemungkinan bahwa gangguan musiman selama periode anomali membatasi keunggulan prediktif spesifikasi model musiman. Model dengan kinerja terbaik kemudian diterapkan untuk meramalkan harga beras untuk periode Desember 2025 - November 2026, dengan proyeksi harga yang relatif stabil di sekitar Rp. 14.809/kg. Temuan ini memberikan informasi awal yang dapat ditindaklanjuti bagi pemangku kepentingan regional dalam pemantauan dan pengelolaan harga beras jangka pendek.

Abstract

Delayed graduation is one of the academic issues that can affect the effectiveness of higher education management and the quality of graduates. This problem is also experienced by students of the Mathematics Education Study Program at Universitas Nusa Cendana, where many students have not completed their studies on time. This study aims to identify the factors influencing the risk of delayed graduation among students of the Mathematics Education Study Program at Universitas Nusa Cendana using a binary logistic regression model, considering both academic and non-academic factors. It also aims to determine the most dominant factor contributing to delayed graduation and to evaluate the model’s ability to classify and predict students’ graduation status. The dependent variable is graduation status, categorized as delayed graduation and on-time graduation. The independent variables include academic and non-academic factors. This study uses primary data collected through questionnaires distributed to students of the Mathematics Education Study Program at Universitas Nusa Cendana. The sample consisted of 96 students from the 2021/2022 cohort. The results indicate that gender, the number of repeated courses, and learning motivation significantly influence delayed graduation. The binary logistic regression model was able to predict students’ graduation status with an accuracy rate of 88.5%.

Abstract

This study aims to analyze students' conceptual understanding of triangle concepts in Euclidean and Non-Euclidean geometry through the implementation of exploratory learning. The study was conducted using a quantitative descriptive approach involving 30 twelfth-grade students at SMA Methodist Antiokhia Pancur Batu. Data were collected through observation and a Likert-scale questionnaire consisting of 20 statement items based on four indicators, namely understanding of Euclidean geometry, understanding of Non-Euclidean geometry, conceptual understanding of triangles, and cognitive impact of learning. The data were analyzed using descriptive statistical techniques by calculating the mean score of each indicator, which generally fell into the high category (range 2.98–3.41), with understanding of Non-Euclidean geometry still slightly lagging behind the other three indicators. The key finding of this study is that exploratory learning effectively encourages students to build a deeper conceptual understanding of triangles through observation, analysis, and discussion, rather than relying on rote procedural memorization. More importantly, integrating Euclidean and Non-Euclidean geometry within a single learning sequence was shown to broaden students' way of thinking: students came to understand not only the properties of triangles on flat planes but also that these properties can change on curved surfaces, resulting in a more flexible and contextual understanding of geometry. These findings imply that an integrative approach combining Euclidean and Non-Euclidean geometry has potential as an alternative strategy for teaching geometry at the senior high school level to foster students' critical and analytical thinking skills, while also addressing the gap in Non-Euclidean geometry instruction that remains rarely introduced at the secondary education level.

Abstract

This study aims to compare the solution of systems of linear equations (SLE) using the Gaussian elimination method through Windows and Android-based applications. This study is a comparative study with a quantitative descriptive approach focusing on the analysis of calculation results and the efficiency of software usage in the context of numerical analysis. Data were obtained from two SLE problem scenarios involving fractional and decimal coefficients, which were then solved using several applications, namely Maple, Microsoft Excel, and the Gauss-Elim calculator. The analysis was conducted based on aspects of accuracy, efficiency, possibility of errors, and ease of use. The results show that Windows and Android-based applications produce the same solutions despite following different solution procedures. Maple demonstrates a high level of accuracy with a systematic and structured solution process. Microsoft Excel requires greater precision because most procedures are carried out manually through elementary row operations. Meanwhile, the Gauss-Elim calculator is the most practical and efficient application because it can display solutions automatically in a short time. Therefore, each application has its own advantages and limitations in supporting SLE solutions using the Gaussian elimination method.
