Abstract

One of the impacts of the Teacher Center Learning (CTL) learning model in the classroom is that students' thinking creativity is less developed and students ability to solve problems is low. This study aims to analyze the problem-solving ability of Animal Ecology Biology Education students based on field-dependent and field-independent cognitive styles. This research is a descriptive study using a qualitative approach. The subjects of this study were Biology Education students in the sixth semester (VI) who programmed animal ecology courses totaling 24 people. The research instrument was the Group Embedded Figure Test (GEFT) which amounted to 25 points. Problem-solving questions in the form of descriptions of 4 numbers and interview guidelines. Based on the results showed that the problem-solving ability of students with field-independent cognitive style is better than field dependent because students with field-independent cognitive style are able to separate themselves from their environment while students with field-dependent cognitive style are still influenced by the surrounding environment.

Abstract

Molecular simulation, a cornerstone of computational chemistry, has revolutionized the understanding and design of chemical reactions. This study explores the application of computational chemistry methods in elucidating reaction mechanisms and guiding molecular design. Employing diverse algorithms rooted in classical and quantum mechanics, molecular simulations unravel the dynamic behavior of molecules, offering insights into spatial arrangements and temporal evolution. A comparative analysis of simulation algorithms reveals their mathematical foundations, exemplary applications, and computational costs. Standard computational modeling methods, including Density Functional Theory and molecular mechanics, strike a balance between accuracy and efficiency. Case studies demonstrate the efficacy of molecular dynamics and quantum mechanics calculations in dissecting enzymatic, organic, and gas-phase reactions. Computational methods contribute to predicting reaction pathways and mechanisms, accelerating the discovery of novel reactions. In molecular design, simulations guide conformational analysis and electronic structure predictions, culminating in successful drug discovery, materials science, and catalysis outcomes. Challenges, opportunities, and practical applications in research and industry are discussed. This study underscores the transformative role of molecular simulation in shaping the future of chemical research and molecular design.

Abstract

Kelor merupakan tanaman endemik di Sulawesi Tengah. Khususnya di Kabupaten Sigi tanaman kelor dapat tumbuh dengan subur. Daun kelor dapat dimakan sebagai sayuran dan juga digunakan untuk tujuan pengobatan dalam keadaan segar, kering atau diolah menjadi bubuk. Diantarannya menjadi teh kelor untuk meningkatkan nilai ekonomis. Untuk itu dilakukan pelatihan pembuatan teh kelor pada kelompok masyarakat. Peserta pelatihan yaitu kelompok banua kelor “Yasmin” di Desa Beka Kabupaten Sigi berjumlah 30 orang. Pelatihan dilaksanakan dengan cara penyajian materi, praktek dan pendampingan pembuatan teh kelor, serta pemberian angket respon peserta. Hasil pelatihan yaitu; 96.67% peserta memahami dengan baik langkah pembuatan teh kelor, 86.67% dapat mengembangkan pembuatan teh kelor, 100% pelatihan sangat bermanfaat, dan 83.33% banua kelor perlu melakukan kerja sama dengan tim pengabdi dalam pengolahan produk kelor. Hasil pelatihan menunjukkan bahwa kelompok banua kelor mengikuti dengan baik pelatihan pembuatan teh kelor.

Abstract

This community service activity is motivated by the importance of improving elementary school teachers' competencies in designing differentiated learning, given the challenges faced in meeting the diverse needs of students. In Tanantovea District, many teachers do not fully understand the concept and application of effective differentiated learning. The purpose of this activity is to improve teachers' skills in designing and implementing differentiated learning through a learning community approach. Research focused on quantitative aspects aims to provide a systematic and factual overview of the factors, characteristics, and relationships between phenomena. Qualitative research is viewed as a process of exploring and strengthening predictions about phenomena based on field data. Following this activity, there was a significant increase in teachers' understanding and skills in designing differentiated learning. Teachers demonstrated improved skills in adapting teaching materials to the diverse needs of students in differentiated lesson plans using word walls. Furthermore, the former learning community strengthened collaboration among teachers and enabled them to share experiences and solutions to challenges. Post-test results indicated an increase in teachers' practical abilities in implementing more interactive and relevant differentiated learning techniques. This activity successfully improved elementary school teachers' competency in designing differentiated learning through a learning community approach, which has proven effective in supporting teacher professional development.

Abstract

Problem-Based Learning is a learning model that focuses primarily on problems in the learning process. It encourages students to collaborate in groups to solve problems through various activities. The purpose of this study was to determine the effect of the Problem-Based Learning (PBL) model on students' numeracy literacy skills in acid-base material. This study used a quantitative, true-experimental design. The research population consisted of 47 students. The research sample was obtained using purposive sampling, divided into an experimental class of 15 students from class XI MIA 2 and a control class of 16 students from class XI MIA 1. The research instruments included a literacy test comprising 20 multiple-choice questions and a numeracy test comprising five essay questions. Experts validated all instruments provided. Data analysis used the Mann-Whitney test. The results of the data analysis showed that the Mann-Whitney test p-value (0.000) was lower than the predetermined significance level of 0.05. Therefore, it can be concluded that the PBL learning model affects students' numeracy literacy skills.
