Abstract

Applying a presidential democratic system to a multiparty system has become a fascinating and controversial topic in recent years. Several countries, including Indonesia, have implemented a presidential system accompanied by a multiparty system to improve the quality of democracy and government stability. This research examines the effectiveness of implementing a presidential democratic system in a multiparty system, focusing on government stability and implications for effectiveness. Using normative juridical legal research methods shows that implementing a multiparty system in a presidential government system weakens the presidential system and has implications for executive and legislative relations. Three things have repercussions: first, the many interests of political parties that conflict with government policy; second, the absence of a permanent coalition arrangement; and third, the weakness of the President's position. Ideally, implementing a multiparty system, stability, and effectiveness of government requires extra balance, firm government, and authority in developing the government system. It can be concluded that implementing a presidential democratic system in a multiparty system has several significant implications for the stability and effectiveness of government.

Abstract

In this study, we present a novel approach to model epileptic seizures using a perturbed Lorenz attractor combined with Bessel filtering. The Lorenz attractor, known for its chaotic behavior, is modified by introducing stochastic perturbations to simulate the irregular and complex patterns observed in epileptic EEG signals. By applying a Bessel filter, we enhance the signal’s temporal characteristics, ensuring the preservation of critical information. Our results demonstrate that this methodology effectively captures the chaotic dynamics inherent in epileptic episodes, providing a clearer and more accurate representation of the signal. This approach holds significant potential for improving the diagnosis and understanding of epilepsy, paving the way for advanced treatment strategies.

Abstract

Education is very important nowadays. Education plays an important role in improving human resources. Children are asked to be able to understand various sciences well, one of which is geometry in mathematics lessons. However, there are still many children who have difficulty getting a decent education, especially children with intellectual disabilities. This article aims to review effective learning methods for students with intellectual disabilities in understanding geometric material and being able to apply it in solving problems in real life contexts. One branch of mathematics that needs to be studied in depth is geometry. Since childhood, we have started to recognize objects that actually use geometric shapes. These objects are even simple objects that we often encounter around us. Apart from knowing the shapes and formulas in geometry, we are also expected to be able to apply geometry in everyday life. Students with intellectual disabilities are expected to have numerical abilities in solving geometry problems. This research uses a qualitative descriptive method by describing and analyzing data related to the discussion. Students with intellectual disabilities need learning media that can be more interactive and can increase understanding and creativity in thinking. By using artificial intelligence teachers can develop more effective learning media for students.

Abstract

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that is resistant to beta-lactam antibiotics. MRSA is transmitted through skin/object contact and is often found in health care and the community. MRSA infection has a high mortality and morbidity rate because it causes sepsis, septic shock, respiratory failure, and amputation. Lactobacillus plantarum produces bacteriocin. The growth of both gram-positive and gram-negative bacteria can be inhibited by this bacteriocin. Purpose: To determine the effect of pH on the activity of bacteriocins produced by Lactobacillus plantarum against MRSA. Method: This research used quasi-experimental methods. L.plantarum was grown in liquid MRS media for 48 hours. Bacteriocin was obtained by centrifuging an MRS broth containing bacteria at a speed of 6000 rpm for 40 minutes. Using the Kirby Bauer method, the liquid formed was tested for its antibacterial effect against MRSA bacteria. Bacteriocins were treated with different pH, namely, 2, 4, 6, 8, and 10. The diameter of the inhibition zone formed during the testing process is measured in millimeters. Data were analyzed using the ANOVA method. Finding: The bacteriocin activity produced by Lactobacillus plantarum against MRSA shows an average diameter of the inhibition zone of 3 mm. The optimum broadest spectrum of antibacterial activity was shown in bacteriocins treated with pH 2. Conclusion: This study shows the results that pH does not affect the antibacterial activity of bacteriocins produced by L.plantarum against MRSA. Originality/Implication: The results of this study prove that various pH treatments do not affect the ability of the bacteriocin produced by L.plantarum to inhibit/kill MRSA.

Abstract

This study aims to examine whether there are differences in management team compensation of different ownership types and their role in moderating the effect of political connections on management team compensation. The population of this study were all companies listed on the IDX in 2018-2022 with sampling techniques using purposive sampling. The test results using the Fixed Effect Model show that there is no difference in management team compensation in different ownership types. On the other hand, the type of company ownership strengthens the influence of political connections on team compensation management. These results strengthen the notion that non-SOE companies utilize political connections to sustain by providing higher rewards.
