Abstract

Research has been carried out using gravity methods to identify subsurface structures in the region of Kota Lama Semarang as a preliminary survey for disaster mitigation purposes. In processing gravity data to identify subsurface structures, several processing stages are carried out. The initial step is to make the initial correction in the form of tide correction and float correction then a further correction is performed until a complete Bouguer anomaly contour is obtained. From the complete Bouguer anomaly, regional and residual gravity anomalies can be separated. The separation of regional anomalies from Bouguer anomalies in this study uses the moving average method while residual anomalies are obtained by subtracting Bouguer anomalies from regional anomalies. In the study of identification of subsurface structures it is important to conduct regional and residual anomaly separations to interpret geological structures and obtain the targets sought. Regional anomaly values in the region of Kota Lama Semarang are between 28.0 mGal - 28.4 mGal while for residual anomalies have between 31.6 mGal - 32.8 mGal.

Abstract

Tujuan artikel ini untuk menganalisis literasi sains peserta didik pada mitigasi bencana alam yang terjadi di Kota Semarang berdasarkan lokasi kejadian, yaitu dekat dengan bencana dan jauh dari bencana. Metode penelitian ini adalah mixed methods sequential explanatory dengan desain penelitian one shoot case study. Pengambilan sampel menggunakan teknik purposive sampling di SMAN 7 Semarang sebagai sekolah dekat daerah bencana (SMA A), dan SMAN 11 Semarang sebagai sekolah jauh dari daerah bencana (SMA B). Pengumpulan data dilakukan menggunakan instrument tes berbasis literasi sains, angket, serta wawancara terhadap beberapa peserta didik yang mewakili kriteria aspek kognitif. Berdasarkan analisis data, ditunjukkan tidak adanya perbedaan literasi sains peserta didik yang berada dekat dan jauh dari lokasi bencana alam. Hal tersebut dilihat dari persentase rata-rata tiap aspek literasi sains SMA A dan SMA B yang termasuk kriteria kurang sekali. Dengan demikian dapat disimpulkan bahwa jarak sekolah dengan lokasi bencana tidak memengaruhi literasi sains peserta didik. Kata kunci: literasi sains, mitigasi bencana, tanah longsor  ABSTRACT The purpose of this article is to analyze students' science literacy in mitigating natural disasters that occur in Semarang city based on the location of the incident, which is close to the disaster and far from the disaster. This research method is a mixed methods sequential explanatory with a one shoot case study research design. Sampling using purposive sampling technique at SMAN 7 Semarang as a school near the disaster area (SMA A), and SMAN 11 Semarang as a school far from the disaster area (SMA B). The data was collected using a science literacy-based test instrument, a questionnaire, and interviews with several students who represent the criteria for cognitive aspects. Based on data analysis, it was shown that there were no differences in science literacy of students who were near and far from the location of natural disasters. This can be seen from the average percentage of each aspect of science literacy in SMA A and SMA B which is categorized as very poor. Thus, it can be concluded that the distance between the school and the disaster location does not affect students' science literacy. Keywords: disaster mitigation, landslide, science literacy

Abstract

This activity was motivated by the fact that Semarang district was declared by the National Disaster Management Agency (BPBN) as a drought-prone area. Plumutan Village became one of the villages in the Bancak sub-district, Semarang district in 2019 .. The methods used are lectures, discussions, and training. For training on the use of appropriate technology, Dowsing and Geoelectricity is carried out in practice in a predetermined location. The results of the activity showed that the participant's experience increased by being given the practice of making and using dowsing to obtain initial information on the position of areas that have groundwater potential, and experience in using geolistic tools assisted by the service team in several locations that had been determined by the Dowsing tool. The results of geoelectric measurements are then processed using the IP2Win device to obtain a cross-sectional map of the soil layer which shows that at point 1 the depth of the aquifer is 87.4 m and point 2 is at a depth of 83.6 m.
