Abstract

The stock price is the stock price of a company are traded on the stock market. The stock prices can rise, fall, or remain stable. The stock price movements are important in the stock market because they provide information about company performance, market sentiment and other economic factors. This makes stock price movements important to monitored by investors, analysts and other market participants to make the right investment decisions when to buy or sell these stocks. In this research, will be carried out stock price forecasting PT. Bank Rakyat Indonesia (Persero) Tbk with the Auto Regressive Integrated Moving Average (ARIMA) method. The ARIMA method is a method that used in time series analysis to model and predict data that has certain patterns. The ARIMA method is used to predict future values based on historical data. The data used is the stock price data of PT. Bank Rakyat Indonesia (Persero) Tbk that obtained from the Yahoo Finance website. The results of this research produced the best ARIMA model, namely ARIMA (1,1,1).

Abstract

This research aims to develop a bilingual mathematics module for KSM in the field of integrated mathematics. The research method uses the Research and Development (RnD) method of the Borg and Gall model which is simplified in 4 stages, namely introduction, development, testing and dissemination. The results of the development of a bilingual (Indonesian-Arabic) mathematics module at KSM are suitable for use. The validation results from media experts have an average value of 3.69 and are in the suitable category for use. Media expert validation has an average value of 3.70 and is in the category suitable for use. The validation results by practitioners have an average value of 3.62 and are in the suitable category for use. Trials by subject teachers had an average score of 3.71 and were in the very interesting category. The individual trials had an average score of 3.61 and were in the very interesting category. Small group trials in each madrasah had an average score of 3.83 and were in the very interesting category and large group trials had an average score of 3.74 and were in the very interesting category. The final stage is dissemination carried out by distributing bilingual mathematics module books.

Abstract

In this paper discussed about ship heading control problem. Ship heading control is one of the ship control problem in the application in the marine field. With rudder angle as input control, the heading angle controlled therefore it can reach reference heading angle with minimum energy. Assume that is wave disturbance to the system. We compare two method for control the heading angle, that is Proportional Integral Derivative (PID) and Model Predictive Control (MPC). Proportional Integral Derivative (PID) is a controller that determine the presition of an instrumentation system with feedback characteristic on the system. MPC is a control technique, which embeds optimization within feedback to deal with systems subject to constraints on inputs and states. From the simulation result, MPC can compansate the disturbance better than PID. The time to reach reference angle when controlled using MPC faster than using PID. The change value of Np also almost give same result. But the change parameter PID can give very difference result seen from the rise time, the settling time, and the overshoot.

Abstract

Tujuan penelitian ini adalah untuk mendeskripsikan kemampuan pemecahan masalah mahasiswa dalam menyelesaikan masalah aljabar linier ditinjau dari gaya kognitif. Gaya kognitif yang dimaksud pada penelitian ini adalah gaya kognitif field dependent (FD) dan field independent (FI). Langkah yang digunakan dalam menyelesaikan masalah ini yaitu dengan menggunakan Langkah Polya dengan melalui empat tahap, yaitu memahami masalah, merencanakan penyelesaian masalah, melaksanakan perencanaan penyelesaian masalah, dan memeriksa kembali. Jenis penelitian ini adalah penelitian deskriptif kualitatif. Penentuan subjek dalam penelitian ini yaitu berdasarkan skor hasil tes Group Embedded Figures Test (GEFT) untuk mengetahui gaya kognitif mahasiswa dan hasil tes pemecahan masalah untuk melihat kemampuan pemecahan masalah mahasiswa. Subjek penelitian ini adalah satu subjek memiliki gaya kognitif field dependent (SFD) dan satu subjek memiliki gaya kognitif field independent (SFI). Hasil penelitian ini adalah SFI dapat memenuhi keempat langkah pemecahan masalah yaitu dengan memahami masalah, merencanakan penyelesaian masalah, melaksanakan penyelesaian masalah, dan memeriksa kembali hasil jawaban yang diperoleh dari masalah yang diberikan dengan baik. Sedangkan untuk SFD masih kurang lengkap dalam memahami masalah dan merencanakan penyelesaian masalah sehingga mengakibatkan kurang lengkap pula penyelesaian masalah yang diberikan. SFD juga tidak memeriksa kembali hasil akhir yang diperoleh.

Abstract

Penelitian ini bertujuan untuk menganalisis penerapan etnomatematika dalam pembelajaran matematika di sekolah dasar dengan mengintegrasikan nilai-nilai budaya lokal, khususnya budaya Aceh, guna meningkatkan pemahaman konsep matematika dan melestarikan warisan budaya. Pendekatan ini memanfaatkan elemen budaya lokal seperti motif kain songket, desain rumah adat, dan seni tradisional sebagai media pembelajaran matematika. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa etnomatematika mampu meningkatkan motivasi dan pemahaman siswa terhadap konsep matematika abstrak melalui konteks budaya yang familiar. Siswa merasa lebih terhubung dengan pembelajaran, sehingga mampu memahami konsep seperti simetri, pola, dan geometri secara lebih konkret. Selain itu, pendekatan ini berkontribusi terhadap pelestarian budaya lokal dengan mengenalkan siswa pada elemen-elemen budaya yang mulai jarang ditemui dalam kehidupan sehari-hari. Namun, tantangan yang dihadapi meliputi keterbatasan sumber belajar berbasis budaya lokal, minimnya pelatihan guru dalam memahami dan mengintegrasikan budaya ke dalam pembelajaran, serta kendala waktu dalam penerapan di kelas. Solusi yang disarankan meliputi pengembangan bahan ajar berbasis etnomatematika, pelatihan guru secara berkala, dan dukungan kebijakan dari pemerintah untuk memperkuat integrasi budaya dalam pendidikan. Penelitian ini menunjukkan bahwa etnomatematika tidak hanya berperan dalam meningkatkan kualitas pembelajaran matematika tetapi juga dalam membentuk karakter siswa yang mencintai dan bangga terhadap budaya lokal, sekaligus mendukung prinsip Kurikulum Merdeka.

Abstract

This study aims to investigate the effect of lecture timing on learning outcomes in Multivariable Calculus using One-Way ANOVA. The type of research is quantitative. The subjects of this study are students of the Mathematics Education program at Jember University from class of 2023, for the Academic Year 2024-2025, enrolled in the regular Multivariable Calculus course. The samples were purposively selected: Class A (morning class) with 35 students, Class B (afternoon class) with 37 students, and Class E (evening class) with 30 students. The sample data were free of outliers, normally distributed, and homogeneous. The results show that and p-value < 0.05, indicating that at a 95% confidence level, there is at least one pair of treatments with significantly different average learning outcomes. Based on the Post Hoc test, significant differences in average learning outcomes were found between Class A and Class B, and between Class A and Class E, while betweet Class B and Class E did not show significant differences in average learning outcomes. Keywords: learning outcomes, lecture timing, One-Way ANOVA
