Abstract

The SEIR (Susceptible-Exposed-Infectious-Recovered) mathematical model, represented as a system of nonlinear differential equations, has proven to be a powerful tool to describe the dynamics of the spread of infectious diseases such as COVID-19. The accuracy of the projection and understanding of this model relies heavily on the proper estimation of its parameters, such as transmission rate, incubation rate, natural birth rate, natural death rate, disease mortality rate, and recovery rate. This study focuses on the development and application of a new approach to estimate crucial parameters in the SEIR model by utilizing Particle Swarm Optimization (PSO). PSO is a metaheuristic optimization algorithm inspired by the social behavior of flocks of birds or schools of fish. PSO was chosen for its outstanding ability to find a global minimum in a complex search space, as well as its efficiency in handling nonlinear optimization problems. The advantage of PSO lies in its effective memory capacity, which allows the storage of previous best values, both individually and globally, thus accelerating convergence to the optimal solution. Through a simulation program, this study successfully identified the optimal set of parameters for the SEIR model. These estimated parameters were then carefully evaluated by comparing the model simulation outputs with available COVID-19 epidemiological data, demonstrating the model's ability to accurately replicate pandemic trends. The results of this study are expected to make a significant contribution to modelling and understanding the spread of COVID-19.

Abstract

This study is a systematic literature review (SLR). The purpose of this study is to determine research trends related to the use of augmented reality (AR) in biology learning from 2020 to 2024. The method used is the PRISMA method. The database used for article searches is Google Scholar. The keywords used in the article search are "augmented reality," "biology education," and "biology learning". From the search results, 300 articles were obtained. Then, these articles were selected according to the inclusion and exclusion criteria, resulting in 57 articles being reviewed. The reviewed article is an article that comes from both national and international journals. The findings reveal that the trend of research related to the use of augmented reality in biology learning has experienced a significant increase. The highest number of articles related to augmented reality were published in 2024. The trend of the most commonly used research methods is the quantitative method. Cells, viruses, the human skeletal system, and the human digestive system are the most commonly used topics in developing augmented reality for biology learning. Based on the dependent variables examined in this SLR study, the most investigated variables are students' cognitive learning outcomes, motivation, and critical thinking skills. In terms of data collection instruments, the most commonly used instrument is the test instrument. Through this SLR, we hope that future studies related to augmented reality will continue to develop considering the rapid advancement of technology. For researchers, they can develop AR research using qualitative or mixed methods to obtain more detailed information or develop other research methods such as CAR or DDR, as they are not yet widely encountered.

Abstract

This study aims to describe the Science Process Skills (KPS) of grade XI Science students at SMAN 5 Tuban through the practicum of making eco-enzymes made from organic waste. The research uses a descriptive method with a quantitative approach and will be carried out in May 2025. The subjects in the study were 30 students of class XI Science-2 who were determined by purposive sampling technique. The research instrument is in the form of a science process skill observation sheet that has been validated by experts, while the data is analyzed using descriptive statistics. The results showed that students' basic Science Process Skills (KPS) in eco-enzyme material in the observation indicator with a percentage of 62.5% in the very good category, a classification of 75% in the good category, and a measurement of 62.5% in the very good category. Meanwhile, predictive skills obtained a percentage of 68.1% in the good category, attracted conclusions obtained 56.3% in the good category, and communicated results with a percentage of 25% classified as in the good category. Nevertheless, overall students have been skilled and appropriate in carrying out eco-enzyme practicum.

Abstract

This study aims to analyze the suitability of the biology teaching module of class X at SMA Negeri 5 Tuban with the standard of teaching module components in the implementation of the Independent Curriculum. This study uses a descriptive method with a qualitative approach. The object of the research is in the form of biology teaching modules for class X odd semesters compiled by biology subject teachers. Data collection was carried out through document analysis and observation, while data analysis was focused on the review of general information components, core components, and attachments to teaching modules. The results of the study show that the teaching module as a whole has been made in accordance with the applicable provisions and is included in the appropriate category. Most of the components of the teaching module have been fulfilled well, although there are still some components that need to be improved, especially in the elaboration of student targets and enrichment and remedial planning. This study shows that the biology teaching module for class X is suitable for use as a learning tool in the Independent Curriculum, but still needs to be refined to be more adaptive to the learning needs of students.
