Abstract

The numerous applications of nanochitosan in a variety of sectors, including medicine, food, and agriculture, attract researchers to work toward the development of environmentally favorable, safe, and efficient synthesis methods. Currently, a biological approach is being developed to synthesize nanochitosan to address the limitations of conventional methods. The synthesis of biogenic pathways employs biological entities, including plant extracts and microorganisms, as nanoparticle-forming agents. The use of extracts is more desirable due to the simple working procedure, the absence of hazardous chemicals, the economic benefits, and the use of basic equipment. This article highlights the role of biomolecules in plant extracts, including polyphenols, terpenoids, citric acid, alkaloids, and polysaccharides, in the synthesis of nanochitosan. Nanoparticle preparation protocols and characterization using zeta potential analysis techniques, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-visible spectroscopy, and Fourier transform infrared spectroscopy (FTIR) are briefly described. The potential applications of green nanochitosan are also discussed, considering the results of biological activity testing and the potential mechanisms associated with these activities. According to the results of numerous studies highlighted in this review, nanochitosan synthesis utilizing plant extracts appears to be a promising alternative approach to conventional methods.

Abstract

Low science process skills contribute to a lack of learner autonomy among students. This research aims to develop teaching materials on elasticity and Hooke's law oriented towards learner autonomy to enhance science process skills suitable for the learning process. The study follows the ADDIE development model (analyze, design, develop, implement, and evaluate). The research subjects were 32 students from class XI MPA 1 at SMA Negeri 6 Banjarmasin. Data were collected through validation sheets, observation sheets on the implementation of lesson plans, observation sheets on science process skills, and learning outcome tests. Quantitative data analysis methods were employed. The results indicate that: 1) the teaching materials are highly valid according to validator assessments, 2) the materials are highly practical based on lesson plan implementation, 3) the effectiveness of the teaching materials is moderate, and 4) students' science process skills are categorized as good based on student activity sheets. In conclusion, learner-autonomy-oriented teaching materials are suitable for training science process skills in the topics of elasticity and Hooke's law.

Abstract

The Effect of Physics Modeling Learning Module to Improve Science Generic Skills on Momentum and Impulse Topics. The learning process dominated by lectures and the use of conventional teaching materials that are difficult for students to understand leads to low generic science skills in students. One-way, teacher-centered learning causes students to become passive. Meanwhile, abstract and quantitative material on momentum and impulse requires a conceptual and visual approach to make it easier for students to understand. Objectives: This study aims to determine the impact of using physics modeling learning modules on the improvement of generic science skills in impulse and momentum material. Methods: This study employed a quasi-experimental design with a one-group pre-test and post-test approach, applied to 34 students in class X.1, who served as research subjects at SMA Negeri 1 Alalak. The data were analyzed using n-gain scores and a paired sample t-test to determine the magnitude of the effect before and after treatment was administered. Findings: The analysis reveals that the use of effective physics modeling learning modules can enhance generic science skills, yielding an n-gain of 0.81. A substantial difference between the conditions before and after using the physics modeling learning module is also evident in the results of the paired sample t-test, which demonstrates how using the module affects students' development of generic science skills. Conclusion: Physics modeling learning modules have significantly and successfully enhanced students' generic science skills related to momentum and impulse content. Keywords: impulse, module, momentum, physics modeling learning, science, generic skills.

Abstract

Rice washing water contains carbohydrates, vitamins, and minerals that serve as potential substrates for the growth of Lactic Acid Bacteria (LAB). This study aims to isolate and characterize LAB from the traditional East Kalimantan rice variety Beras Mayas. LAB isolation was performed using De Man Rogosa and Sharpe (MRS) Agar, followed by successive purification to obtain pure cultures. Identification of the isolates involved macroscopic and microscopic observations, Gram staining, and a series of biochemical assays. Three distinct LAB isolates, designated A, B, and C, were obtained. Isolates A and B exhibited circular colonies with yellowish-white pigmentation and undulate margins, suggesting affiliation with the genus Lactobacillus. Isolate C formed circular white colonies with entire margins, indicating a possible relationship with the genus Streptococcus. Biochemical testing revealed that all three isolates were negative for catalase, gelatin hydrolysis, motility, and indole production. In the Triple Sugar Iron Agar (TSIA) test, all isolates fermented glucose, lactose, and sucrose, producing yellow coloration in both the slant and butt portions of the medium. These results suggest that the isolates are homofermentative LAB.

Abstract

The rapid advancement of technology has significantly influenced structural engineering, particularly in the design of complex geometries and the analysis of irregular load distributions. Conventional manual calculations often fail to provide precise and reliable results, especially when dealing with large-scale or intricate structural systems. To address these limitations, numerical methods such as the Finite Element Method (FEM) have been developed and widely implemented. FEM divides a structure into smaller elements interconnected through nodal points, enabling detailed analysis of displacements, stresses, and reactions. Alongside theoretical development, FEM has been integrated into computer-based applications that provide more efficient, accurate, and user-friendly tools for structural analysis and design. This paper reviews several widely used FEM-based applications, including SAP2000, ETABS, ANSYS, and ABAQUS. This article utilizes the Literature Review method to review and synthesize findings from four previous studies. Each software offers unique strengths: SAP2000 and ETABS are widely applied in building and general infrastructure design; ANSYS and ABAQUS are well-suited for nonlinear and advanced multiphysics analysis. By comparing these applications, this review confirms the key finding that software specialization (SAP2000/ETABS for infrastructure vs. ANSYS/ABAQUS for advanced non-linear analysis) is crucial. Ultimately, FEM-based applications not only improve the accuracy and efficiency of structural analysis but also enhance safety, reliability, and sustainability in modern construction practices.
