Abstract

This community service activity was carried out in the Bluluk sub-district, precisely in the Kuwurejo village, Bluluk sub-district. This activity aims to provide an understanding to the Kuwurejo village community about the utilization of cow dung waste by processing it into Bokashi organic fertilizer. The method used in this activity uses a material presentation approach and direct practice of making organic fertilizer from cow dung. The results of the training on making bokashi or organic fertilizers that have been carried out can be concluded that the activities went smoothly according to plan. In addition, the enthusiasm of the community is quite high, it can be seen during the training activities for making organic fertilizers, almost 70% of the participants filled the training venue.

Abstract

Understanding the principles of physics, especially in a 2-loop electrical circuit, requires applying Kirchhoff's Laws to form a system of linear equations. While substitution-elimination methods are commonly used to solve these systems, they become inefficient when dealing with more than three variables. As an alternative, Cramer's Rule, which involves using matrix determinants and the cofactor method, proves to be more effective, particularly for larger systems. The research shows that both Cramer's Rule and the matrix inversion method produce consistent results for current calculations. The current values obtained from the first and second circuits match those calculated using the cofactor method. These techniques are not limited to electrical circuits; they can also be applied in other engineering fields, such as dynamic systems analysis and mechanics. A solid understanding of Cramer's Rule, cofactors, and matrix inversion is essential for analyzing both physical and engineering systems. In the first circuit, the results are i₁ = 0.25 A, i₂ = 2.5 A, and i₃ = 2.75 A, while in the second circuit, the results are i₁ = 1 A, i₂ = 2 A, and i₃ = 1 A.
