Abstract

Kota Baru is the satellite city of Bandar Lampung. The city is prepared for the expansion of the city of Bandar Lampung. Zonation map of earthquake risk is required for Kota Baru due to its location within the reach of earthquake energy of Semangko subduction fault. In this study, we model the earthquake-prone zone map based on the soil characteristics (site effect) combined with the underground layer model to get a detailed description of the horizontal and vertical soil character. The microtremor method is performed to obtain the zonation effect mapping. Whereas, the ground layer modeling is obtained using the geoelectrical method. The modeling results show that the study area is far from tectonic activity based on the history of past earthquake events. However, this area has a large sediment thickness and has a low dominant frequency value, so it is an area that is vulnerable to earthquakes.

Abstract

Research on the Effect of Learning Models (Visualization, Auditory, Kinesthetic) Assisted by the Crossword LABS Application to Improve Concept Understanding has been conducted. This study aims to determine the effect of the VAK learning model (Visualization, Auditory, Kinesthetic) assisted by the Crossword LABS application on students' conceptual understanding and to determine the improvement in students' conceptual understanding. The type of research used is an experiment with a research design used by researchers is a quasi-experimental design with a nonequivalent control group design. The population used is class X students of SMA which consists of 3 classes with a total of 75 people. The research sample is class X-2 students as the experimental class and class X-1 students as the control class. The average pretest result of students in the experimental class is 37.2 and the average posttest result is 77.2. Based on the Independent Samples Test, the posttest value with sig. (2-tailed) 0.004 <0.05. This means that H0 is rejected and Ha is accepted. The N-gain score for the experimental class was 64.54, which is categorized as moderate, with the interpretation of N-Gain being quite effective. Therefore, it can be concluded that the Crossword LABS application-assisted VAK (Visualization, Auditory, Kinesthetic) learning model has an impact on improving conceptual understanding.

Abstract

This study aims to determine the effect of using PhET (Physics Education Technology) simulation media on enhancing students’ conceptual understanding of heat and heat transfer at SMP Negeri 1 Cot Girek. The research employed a quantitative approach using a quasi-experimental design with a non-equivalent control group type. The sampling technique used was purposive sampling, involving a total of 50 students Class VII A as the experimental group and Class VII B as the control group, each consisting of 25 students. The instrument used was a multiple-choice test administered as both a pretest and a posttest to measure students' conceptual understanding. The results showed that the average posttest score in the experimental class was 71.4, while in the control class it was only 52.8. Hypothesis testing using an independent sample t-test on the posttest data revealed a significance value of 0.001 ( 0.05), indicating a significant difference between the two classes after the treatment. Meanwhile, the N-gain scores showed an improvement of 71% (high category) in the experimental class and 54% (medium category) in the control class. Thus, it can be concluded that the use of PhET simulation media is effective in improving students’ conceptual understanding of heat and heat transfer, especially in schools with limited laboratory facilities.

Abstract

Desa Keude Krueng kecamatan Kuta Makmur Aceh Utara merupakan desa yang sering mengalami ganguan pasokan gas LPG bersubdisi. Saat ini gas LPG merupakan bahan bakar utama untuk keperluan memasak rumah tangga. Sebagai alternatif solusi untuk mengantisipasi kelangkaan LPG sekaligus mengurangi ketergantungan terhadap satu jenis bahan bakar, maka dirancang sebuah kompor roket biomassa untuk kebutuhan rumah tangga yang berbahan ranting kayu dan limbah biomassa lainnya yang mudah diperoleh di lingkungan desa. Kompor roket merupakan kompor tungku yang terbuat dari besi dengan bentuk seperti cerobong asap dengan bahan bakar kayu/ biomassa. Pelaksanaan pengabdian ini dilakukan dengan memberikan edukasi dan bimbingan tentang cara penggunaan kompor roket biomassa sebagai pengganti bahan bakar fosil. Bimbingan yang dilakukan bertujuan agar masyarakat lebih menyadari akan pentingnya memanfaatkan limbah kayu ranting yang terdapat di desa mereka untuk dijadikan bahan bakar disaat LPG dan minyak tanah mengalami kelangkaan. Hasil dari kegiatan ini adalah tumbuhnya kesadaran masyarakat bahwa limbah yang berada disekitar mereka dapat dimanfaatkan secara efisien bagi kebutuhan rumah tangga secara aman dan ramah lingkungan.
