Abstract

Forest and land fires are a recurrent issue in several Indonesian regions, necessitating advanced technological solutions for early detection and monitoring due to their significant impact. This research project focuses on developing a prototype system utilizing IoT-based Wireless Sensor Network (WSN) technology to detect forest and land fires. The prototype offers real-time remote monitoring of temperature, humidity, smoke levels, and wind speed in the forest through an Android app or web interface. To validate its performance, the prototype was compared to existing BMKG tools, with results showing minor temperature errors (2.41%) and a humidity error of 17.68%. The anemometer sensor exhibited a slight 4-second data transmission delay. Importantly, the prototype excelled in fire detection, effectively identifying temperature and humidity changes within a 2-meter radius or more indicative of fire outbreaks. This pioneering prototype promises to significantly enhance early warning and response mechanisms for forest and land fires in Indonesia, contributing to more effective environmental conservation and disaster management.

Abstract

Achieving 21st century skills is anticipated by managing learning based on scientific literacy. This literacy is the life skills of students, so they can solve existing problems by collaborating in thinking scientifically. Scientific literacy is defined as an understanding of the characteristics of science as a form of knowledge, awareness, intellect, and culture that involves science. Low science learning can be indicated by students' low scientific literacy. To increase students' scientific literacy, a learning model that supports this is needed. One learning model that can be used is the cognitive conflict-based learning model. Considering the phenomena and demands of students, researchers want to develop an e-module based on cognitive conflict integrated with augmented reality to increase students' physical literacy in physics materials. The type of research conducted was Design Research (Design Research). The development model used in this study was the Plomp model. The data analysis technique used a validation sheet questionnaire, analyzed using presentation techniques, and the V-Aiken formula. The results of data analysis obtained a validity value of 0.93 with the valid category, this was obtained because the e-module developed was in accordance with material substance, learning design, visual communication display, and software utilization.

Abstract

Natural treatment is plant extract nanoemulsion. Forming nanoemulsions with a specific method may help skin wound healing. Fruit cardamom (Amomum compactum Sol. Ex Maton) was used as an antimicrobial, but its wound-healing activity was unstudied. This study compares nanoemulsion from cardamom seed ethanol extract to cardamom extract in suppressing bacterial growth, wound healing, and determining component makeup. Research methods with Lab experiments involve sampling, processing, extracting, and UV-VIS spectrophotometer testing secondary metabolite chemicals, creating nanoemulsions, and characterizing them with HPLC, FTIR, UV-VIS, and PSA. TPC and disc diffusion for antibacterial and wound healing characterization and SPSS analysis. The research results found high quantities of gallic acid, catechin, and epigallocatechin were found in 20% (v/v) cardamom extract nanoemulsion, with HPLC analysis showing levels of 4590.10 µg/mL, 2128.95µg/mL, and 755.42µg/mL, respectively. FTIR and UV-Vis tests indicate a single peak around the phenol compound's absorption area and describe its group by absorbing functional groups in the IR spectrum. Nanoemulsion suppressed E. coli and S. aureus better than cardamom extract. At 1% (v/v), nanoemulsion heals wounds faster than cardamom extract and gentamicin sulfate. The particle size of 53.13 ± 1.25 nm and particle size distribution of 0.56 ± 0.02 nm contribute to the stability and high activity of the nanoemulsion.

Abstract

Problems of kinematics of rectilinear motion in high-level cognitive level problems often display complexity in their solutions. This research aims to describe the use of computational thinking (CT) methods in helping students solve linear motion kinematics problems designed at a high cognitive level (analysis, evaluation, and creation). This research uses a descriptive quantitative method by using skills observation sheets and analysis of performance results as data collection instruments. The sample was 14 students from the Natural Sciences Tadris study program in introductory physics courses. This research's data analysis technique uses an interpretation of student performance results in solving linear motion kinematics questions at a high cognitive level using the performance stages of the CT method. Significant findings show that the average student cannot solve cases at a high cognitive level using CT skills. Students can only complete and pass the stages of computational thinking skills in the temporary decomposition and abstraction phases but have difficulties in the visualization and design stages at the analysis, evaluation, and creation levels.

Abstract

The difference in student’s needs and abilities in learning mathematics made teachers need to vary learning. This study aimed to describe the steps, implementation, and obstacles in the implementation of differentiated learning in mathematics learning in elementary schools. The location of this study was SDN 47/IV Kota Jambi. The subjects of this research were the principal, IVD class teachers, and IVD class students. Qualitative phenomenology was the type of approach used in this study. This study used interview guidelines, observation, and documentation. The data analysis technique used in this study consisted of three stages, namely data reduction, data presentation, and concluding. The results of the study found that differentiated learning in mathematics subjects begins with mapping students' mathematics learning needs, designing learning according to mapping results, and conducting evaluations on an ongoing basis. The implementation of differentiated learning does not mean that in the process it distinguishes all components of learning for one student at a time. The obstacles that are often faced are limited time and lack of experience so it needs adaptation.
