Abstract

The purpose of the activity is to provide experience and train participants to understand geoelectric theory, data collection and processing and analysis packaged in the form of reports, and specifically to obtain real input for curriculum development in universities to be more relevant to development needs. Based on the problems experienced by students of SMK Negeri 9 Energy and Mining Jayapura, a service activity was carried out that intends to explain geophysical methods related to groundwater utilization for agriculture. Students will receive material with a ratio of 50% theory and 50% practice. Through this activity, participants will better understand the concepts in searching for groundwater and be able to develop skills, especially in the development of geophysical tools and be able to interpret the measurement results and resistivity values accurately, measurably and integrated. The results of geoelectric data processing of VES 1-3 points show that VES.1 has a relatively larger specific resistance value when compared to the two measurement points VES.2 and VES.3. This difference is due to the structure of VES.1 in the form of hard rock part of the Ultramafic formation which is composed of rock types such as marl, fine sandstone, tuff, and tuff. The results of geoelectric data processing from the four measurement points show that the measurement points VES. 4, VES. 6 and VES. 7 have relatively low specific gravity values, in contrast to the relatively high value of VES. 5 which is relatively high. The difference in specific gravity values is very influential on the presence of aquifers at each measuring point. Based on the distribution of specific gravity values, the vertical lithology of the four measuring points is arranged by rock types, namely surface rocks, breccias, tuffs, clay stones, and siltstones.

Abstract

Scientific presentation is one of the essential skills that every individual should possess, particularly those involved in the fields of education and research. Classroom learning is often focused on children's ability to memorize. This study aims to determine how presentation skills use the GI type cooperative model. This study used two variables: the independent variable and the dependent variable. The independent variable was the learning model, specifically a cooperative learning model of the group investigation type. The dependent variable in this study was the ability to learn. The type of research used is descriptive qualitative, as the purpose of this study is to provide a comprehensive picture of the phenomenon. The study's results showed an average increase of 17 points, accompanied by a decrease in the standard deviation value from 5.86 to 3.64, indicating the development of presentation skills following participation in GI-type cooperative learning. The results of the normality test on the presentation ability data at the pretest stage showed that the significance value in the Kolmogorov-Smirnov test was 0.116 and in the Shapiro-Wilk test was 0.061, indicating that the pretest data did not deviate significantly from a normal distribution.
