Abstract

Kalisalak Hamlet in Sukoharjo District is faced with the risk of landslides that can affect the structure of residents' houses. This study aims to identify potential landslide zones based on the parameters of Dominant Frequency (f_0), Amplification Factor (A_0), and Seismic Vulnerability (K_g)to determine areas that are potentially vulnerable to landslides. Microseismic measurements were carried out at 25 measurement points in the landslide zone. Measurements used a 3-component digital portable seismograph (North-South, West-East, and Vertical). Microseismic data were processed using Geopsy software with the HVSR (Horizontal-to-Vertical Spectral Ratio) method to obtain an H/V curve that provides Dominant Frequency (f_0) and Amplification Factor (A_0) values. The results showed that Kalisalak Village has a dominant frequency value between 3 Hz to 12.5 Hz and an amplification factor value between 1.4 to 6.8. This variation indicates that some areas are more susceptible to seismic vibration amplification. Based on the Dominant Frequency (f_0) value and Amplification Factor (A_0), a Seismic Vulnerability (K_g) microzonation map was created for Kalisalak hamlet with a value range of 0.2 to 7 with a high vulnerability value located in the landslide area south of the village. This map is important for disaster mitigation planning in Kalisalak hamlet.

Abstract

Pendidikan sains di tingkat dasar memiliki peran yang krusial dalam membentuk pemahaman yang kokoh terhadap dunia sekitar. Kebutuhan akan literasi sains yang inklusif semakin meningkat, menuntut pendekatan holistik yang memperhitungkan realitas sosial, budaya, dan lingkungan tempat siswa belajar. Dalam konteks ini, pendekatan etnosains menawarkan kerangka kerja yang berpotensi untuk memperkaya pengalaman belajar sains siswa dengan mempertimbangkan konteks budaya dan sosial mereka. Tinjauan literatur ini menyajikan temuan-temuan dari berbagai kajian penelitian terkait dengan pendekatan etnosains dalam pembelajaran IPAS di sekolah dasar. Analisis terhadap literatur menunjukkan bahwa implementasi pendekatan etnosains dapat membantu meningkatkan literasi sains siswa dengan memperhatikan kebutuhan khusus mereka, memfasilitasi pengembangan kemampuan berpikir kritis dan pemecahan masalah, serta memperkaya pengalaman belajar melalui integrasi pengetahuan lokal, tradisional, dan kontekstual. Namun, tantangan dalam implementasi pendekatan ini, seperti pemahaman yang mendalam tentang keberagaman budaya siswa dan pengembangan kurikulum yang relevan, juga perlu diperhatikan. Dengan memperhitungkan temuan-temuan ini, penelitian lanjutan dapat mengembangkan strategi dan praktik terbaik dalam penerapan pendekatan etnosains dalam pembelajaran IPAS di sekolah dasar, menciptakan lingkungan pembelajaran yang inklusif dan bermakna bagi semua siswa

Abstract

This study seeks to evaluate the efficacy of PowerPoint-based interactive multimedia in enhancing the cognitive skills of fifth-grade primary pupils. A quantitative experimental methodology employing a one-group pretest-posttest design is utilised. Tests are a data collection method applied in research. Data analysis through descriptive statistics and inferential statistics. The subject of this research is class V of SDN 26 Talang Ubi. The research results showed that the average score for the pretest of students' cognitive abilities = was 69.25, and the posttest for students' cognitive abilities = was 81.75. These results show that there has been an increase in students' cognitive abilities after using interactive multimedia in learning in class V of SD Negeri 26 Talang Ubi. The N-Gain test obtained an average score of 0.3913, which is in the medium category. In conclusion, the use of interactive multimedia has a significant influence on students' cognitive abilities, but its effectiveness is still relatively moderate.
