Abstract

An option is a right by a person or institution to sell or buy an investment instrument at a certain price for a certain period. The point of view for way an option is exercised, there are two types of options known today, namely European options and American options. European options are characterized by option contracts that can only be exercised at the expiration date of the option. American options are indicated by option contracts that can be exercised at any time within the validity of the option contract. There are several methods that can be used in determining option prices, including the Black Scholes method which can be used to calculate the standard price of options. Monte Carlo simulation is a method that gives all possible values of a variable using the average as an estimator of its exact value. Quasi Monte Carlo simulation is an alternative to Monte Carlo simulation which uses quasi-random sequences instead of random numbers. In this article, the quasi-random sequence used is Van der Courput. Calculate option prices with Monte Carlo simulation and Quasi Monte Carlo simulation using MATLAB.

Abstract

Cryptography is a method for securing data or information from data leaks. In cryptography, there are two important processes, namely, the encryption and decryption processes. Encryption is the process of changing plaintext into ciphertext using certain keys and algorithms, while decryption is the process of changing ciphertext into plaintext using keys and algorithms that match the encryption. There is a cryptosystem that is well known, namely Cipher Hill. Cipher Hill uses a square matrix for the encryption and decryption process. In this research, an mxn-sized matrix will be used over the Direct Sum ring Z_p⨁Z_q⨁Z_r to expand the Cipher Hill algorithm. The author also uses the pseudoinverse concept to find the inverse of an mxn matrix. By using an mxn matrix, the encryption results allow the length of the plaintext to be different from the length of the ciphertext.Keywords: Cipher Hill, Cryptography, Decryption, Encryption, Direct Sum, Pseudoinvers

Abstract

Learning Management System (LMS) is an innovation in the learning process that allows online learning to be more effective and efficient. Like many other higher education institutions, Universitas Negeri Malang provides opportunities for innovation and easy access to knowledge by utilizing an LMS called the Sistem Pengelolaan Pembelajaran (SIPEJAR). SIPEJAR is an open-source system that can be modified according to the user's needs and desires. The aim of this research is to develop SIPEJAR content packages by using the ADDIE model for statistics for education courses with drone-based learning. SIPEJAR development products include lesson plans, textbooks, and SIPEJAR content packages for 16 meetings. Drone-based development is focused on developing explanatory videos, presentation slides, and student interaction with learning materials. The finding results indicated that the drone-based development of SIPEJAR content packages is valid with an average score of 3.77 out of 4, practical with an average score of 4.19 out of 5, and quite effective with classical completeness percentage obtained was 60% with an average score of 74.63. This means that drone-based SIPEJAR content packages have been well developed, even though they can be improved further. Our research findings indicated that the E-LKPD is valid with a percentage of 91.00%, practical with a percentage of 89.05%, and effective with a classical learning completeness percentage of 82.76%

Abstract

This community service program aimed to strengthen the capacity of elementary school teachers in integrating traditional games into mathematics learning to support students’ numeracy skills. The activities were carried out through workshops, mentoring in lesson plan development, and classroom implementation. The workshop was conducted on March 6, 2026, at SDN Merjosari 3 and was attended by 33 participants from nine schools in the Kombel Meriang community. The workshop activities included a pre-test, material enrichment sessions, discussions, the preparation of lesson plan mapping based on traditional games, and a post-test. The evaluation results showed an increase in teachers’ average knowledge scores from 94.67 to 97.67, with the minimum score increasing from 76 to 86 and the standard deviation decreasing from 6.6 to 3.8. The mentoring stage was conducted asynchronously from March 7–15, 2026, through the preparation, review, and revision of lesson plans until the final version was completed. The classroom implementation was carried out on April 16, 2026, in a fifth-grade class at SDN Merjosari 3 involving 28 students in a data processing lesson based on the traditional marble game. Data were collected through lesson plan reviews, classroom observations, reflection notes, documentation, and student responses. The observation results showed a learning implementation rate of 96.25%, categorized as very good. The use of games in learning reached 100%, while student engagement reached 97.5%. Student responses indicated that mathematics learning based on traditional games was enjoyable, meaningful, and worthy of further development. Reflection findings highlighted the need to improve the Two Stay Two Stray note sheet, revise the wording of formative assessment questions, strengthen social-emotional and character values, and simplify the game rules. Overall, this program demonstrated that traditional games can serve as an effective learning context to strengthen numeracy, collaboration, and more meaningful mathematics learning experiences in elementary schools.
