Abstract

Mathematics plays a crucial role in the modern financial world, where mathematical concepts are used to model and manage risk, optimize portfolios, and design complex financial instruments. This article discusses various applications of mathematics, ranging from probability theory and statistics to calculus and linear algebra, in the realm of finance. One of its main applications is in cryptography, which involves mathematical techniques to secure digital transactions and personal data. Additionally, mathematics-based trading algorithms, which utilize predictive models and big data analysis, are increasingly used by investors to maximize profits and minimize losses. The article also explores the relationship between option pricing theory and stochastic models used to predict stock price movements. Thus, mathematics not only provides a theoretical foundation but also practical tools that enable financial markets to operate efficiently and securely.

Abstract

Reproduksi merupakan kunci utama dalam pengembangbiakan ternak, karena proses reproduksi ternak yang normal diikuti oleh produksi ternak yang baik. Reproduksi dianggap sebagai salah satu aspek untuk meningkatkan produksi dan populasi ternak. Penelitian ini bertujuan untuk mengetahui efisiensi reproduksi Sapi Donggala di Kabupaten Donggala. Penelitian ini dilaksanakan di 5 kecamatan yaitu Kecamatan Tanantovea, Sindue Tobata, Sindue Tambosabura, Balaesang, dan Banawa Tengah . Penentuan lokasi menggunakan purposive sampling dan responden ditentukan secara accidental sampling. Pengambilan data menggunakan metode sampling terhadap peternak Sapi Donggala di 5 kecamatan tersebut. Data yang dikumpulkan adalah data Tahun 2022.  Variabel yang diamati berupa karakteristik peternak dan data reproduktivitas. Karakteristik peternak terdiri dari umur, pendidikan, dan pengalaman beternak. Sedangkan data reproduktivitas berupa umur pertama dikawinkan, lama kebuntingan, dan Calving Interval (CI).  Hasil penelitian diperoleh umur peternak terbanyak yaitu umur 15-65 tahun (96%), tingkat pendidikan terbanyak yaitu SMP (42%), pengalaman beternak tertinggi yaitu 3-10 tahun (67%), umur pertama dikawinkan tertinggi umur 1,6-2 tahun (46%), lama kebuntingan sebanyak 270-290 hari (69%), dan calving interval (CI) diatas 12 bulan (73%). Hasil penelitian menunjukkan bahwa efisiensi reproduksi Sapi Donggala di Kabupaten Donggala masih tergolong rendah

Abstract

This study was conducted to develop a Learning Module based on ARCS learning motivation model in informatics subjects for class VIII of junior high school. This study used a research and development method (Research and Development) with the ADDIE development model. The trial design used was a one-group pretest-posttest design. The results of the study showed that the learning module developed based on the ARCS model was categorized as very valid, with an average validation of construction experts and material experts obtained a percentage of 95.8% with a very valid category. In the effectiveness test of the learning module in the cognitive domain, there was an increase with an average gain value of 0.61, including the moderate category. So that the results of the validity and effectiveness test of the learning module, a conclusion was obtained that the development of a learning module based on ARCS motivation model in informatics subjects for class VIII of SMPN 15 Malang was declared feasible to use.
