Abstract

The prediction of sharia stock prices is currently an important concern for investors who want to invest according to Islamic principles. Investors generally invest to achieve profits, which are measured by the magnitude of returns or the rate of return on those sharia-compliant stocks. However, there is also a risk of loss if the investor makes the wrong decision. Often, investors simply guess whether the stock price will go up or down. In sharia stock analysis, accurate forecasting techniques are needed to help investors minimize risk and maximize potential returns. This research aims to predict the stock price of Bank Syariah Indonesia (BRIS. JK), which is one of the sharia stocks highly sought after by stock investors. The prediction for the next year is conducted using the multiplicative triple exponential smoothing method as a guide for investors in decision-making. This method was chosen because of its ability to capture seasonal patterns and trends based on historical stock data.  The forecasting results show that the price of BRIS.JK shares will continue to rise over the next year. This provides valuable information for investors to consider investing in that stock. Keywords: predictions, sharia shares, triple exponential smoothing.

Abstract

Monkeypox is an infectious disease whose spread is influenced by various epidemiological factors, one of which is the incubation period. This study developed a mathematical model of Monkeypox, SVEIR, by incorporating a time delay in the transition from an exposed individual to an infectious individual, representing the incubation period. Model analysis shows that the system has two equilibrium points: a disease-free state and an endemic state. Based on the simulation results, a threshold value (tau* ) is obtained, which plays a crucial role in disease control. If the incubation period is below the threshold ( tau<tau*), then R0>1 , and the disease will spread endemically. Conversely, if the incubation period exceeds the threshold (tau>tau* ), then R0<1 , and the disease will disappear from the population

Abstract

Program Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan kemampuan literasi numerasi siswa melalui pembelajaran matematika yang kontekstual dan berfokus pada siswa (student-centered learning). Kegiatan dilakukan melalui program dosen tamu di SMA Muhammadiyah Boarding School (MBS) Zam-Zam Cilongok. Kegiatan ini merupakan bagian dari pelaksanaan kerja sama antara FMIPA Universitas Jenderal Soedirman dengan sekolah mitra. Materi yang dijelaskan mencakup lima topik dalam pembelajaran matematika SMA, yaitu persamaan kuadrat, barisan dan deret, matriks, eksponen, dan sistem persamaan linier. Metode pembelajaran yang digunakan adalah pembelajaran kontekstual dengan pendekatan student-centered learning. Evaluasi dilakukan dengan kuis, pengamatan aktivitas siswa, dan umpan balik dari guru mitra. Hasil kegiatan menunjukkan bahwa lebih dari 80% siswa mampu memahami konsep matematika dengan lebih baik dan berpartisipasi aktif dalam kegiatan pembelajaran. Guru mitra juga memberikan tanggapan yang positif terhadap metode pembelajaran yang diterapkan. Program ini menunjukkan bahwa kerja sama antara perguruan tinggi dan sekolah bisa menjadi model yang efektif dalam mendukung pendidikan berkualitas di lingkungan sekolah.
