Abstract

A system of nonlinear equations is a collection of several interrelated non-linear equations. Currently, systems of nonlinear equations are used not only on crisp but also on fuzzy numbers. A fuzzy number is an ordered pair function that has a degree of membership [0,1]. Meanwhile, a fully fuzzy system of equations is a system of equations that applies fuzzy number arithmetic operations. The solution of non-linear equation systems is usually complicated to solve analytically, so numerical methods are used as an alternative to solve these problems. In this research, the steps to find the solution of nonlinear fully fuzzy equation systems using genetic algorithms are studied, which in the solution process is based on the theory of evolution and natural selection. The solution steps taken are first converting the fully fuzzy system of equations into a system of crisp equations, next constructing the system of strict equations as a multi-objective optimization problem, and lastly solving the optimization problem using a genetic algorithm which includes initialization, evaluation, selection, crossover, and mutation. As illustrations, several cases of nonlinear fully fuzzy and dual fully fuzzy systems of equations on triangular fuzzy numbers and trapezoidal fuzzy numbers are given. The approximate solutions obtained using genetic algorithms produce solutions that are close to their analytic solutions.

Abstract

Corn cobs are agricultural waste that can be processed into an alternative firewood. Carbonization (pyrolysis) followed by briquetting is one method to process biomass into solid charcoal. According to a survey conducted, the large amount of corn cob waste is due to a lack of knowledge in processing waste which causes health and environmental problems. Converting corn cob waste into briquettes transforms it into a valuable commodity. In fact, transforming corn cob waste is essentially applying the zero waste concept to agricultural production systems. Based on potential and agreements with farmer groups, community members, and local government, this service activity was carried out. The productivity of the briquette charcoal business made from corn waste is increased through training and assistance.

Abstract

Pola konsumsi masyarakat di Indonesia merupakan salah satu tolak ukur dalam menentukan indeks perekonomian masyarakat Indonesia. Daya konsumsi masyarakat Indonesia memiliki kontribusi yang sangat penting dalam kenaikan indeks perekonomian di Indonesia.  Dengan melihat faktor yang dapat menentukan pola konsumsi masyarakat Indonesia, pola konsumsi mampu mempertahankan daya konsumsi masyarakat.  Dalam penelitian ini akan dilakukan pencarian pola konsumsi masyarakat perkotaan di Indonesia menggunakan dua algoritma untuk mendapatkan algortima terbaik yang memiliki nilai support, confidence dan rule terbesar, yaitu FP-Growth dan Eclat.  Hasil yang diperoleh digunakan untuk melihat pola konsumsi masyarakat perkotaan di Indonesia.  Nilai support dan confidence terbesar dihasilkan oleh algoritma Eclat sebesar 10% dan 100% dengan rule sebanyak 15 dan pola terbaik yang dihasilkan adalah masyarakat yang mengkonsumsi makanan berdasarkan faktor agama adalah masyarakat yang berusia diantara 30 dan 50 tahun. Kata Kunci:  Association Rule, FP-Growth, Eclat, Support, dan Confidence.

Abstract

This study aims to describe the experiences of Islamic Religious Education teachers in implementing educational technology after participating in training. The research employed a descriptive qualitative approach, utilising data collection techniques that included observation, interviews, and documentation. The results indicate that educational technology training has a significant impact on improving the competency of Islamic Religious Education teachers. First, teachers become more skilled and confident in utilising digital media, such as interactive PowerPoint, Canva, Google Classroom, YouTube, Kahoot, and Google Forms, to present material in a varied and engaging way. Second, teachers are able to integrate technology into their lesson plans in a structured manner, resulting in more innovative and effective learning strategies. Third, the use of technology has been shown to increase student participation, foster creativity, and strengthen collaboration in learning activities. These findings indicate that educational technology training not only improves teachers' technical skills but also shifts the learning paradigm to become more modern, interactive, and student-centred.
