Abstract

Wagir yang berada pada lereng Gunung Kawi mempunyai potensi tanah longsor. Guna memodelkan tingkat kerawanan tanah longsor di Kecamatan Wagir, parameter tanah longsor menurut Puslittanak Bogor tahun 2004 yang dijadikan acuan dalam penelitian ini. Parameter tanah longsor diolah  dengan software ArcGIS 10.8 menggunakan metode scoring dan overlay, sehingga tingkat kerawanan tanah longsor dapat terpetakan. Parameter yang digunakan dalam klasifikasi tanah longsor tersebut yaitu kemiringan lereng, tutupan lahan, dan jenis tanah yang ada. Peta yang dihasilkan menunjukkan tiga tingkat kerawanan tanah longsor di Kecamatan Wagir yaitu rendah, sedang, dan tinggi. Tingkat kerawanan tanah longsor rendah berada di bagian timur Kecamatan Wagir dengan luasan sebesar 1843 ha. Tingkat kerawanan tanah longsor sedang dengan luas 3820 ha berada di bagian tengah Kecamatan Wagir. Sementara itu, tingkat kerawanan tanah longsor tinggi berada di bagian barat Kecamatan Wagir dengan total luasan sebesar 466 ha. Dengan demikian, upaya-upaya dalam meningkatkan dan menjaga stabilitas lereng perlu dilakukan, khususnya di daerah dengan tingkat kerawanan yang tinggi.

Abstract

The guided inquiry (GI) model is one of the scientific learning models that is student centered and designed to stimulate spatial thinking skills through discovery activities under the guidance and direction of the teacher. In addition to the learning model, geoliteracy is another factor that influences students spatial thinking skills. This study aims to determine the effect of the GI model on spatial thinking skills and to examine the effect of the GI learning model on spatial thinking skills in terms of students geoliteracy. The research method is a quasi experimental design with a post test only design. The population of this study consists of eleventh grade students at SMAN 5 Malang and SMAN 6 Malang, with purposive sampling used to determine the control and experimental classes at each school. Data were collected using a test instrument to obtain spatial thinking ability scores and geoliteracy scores. Data analysis was carried out using independent sample t tests and two way anova. The results show that the GI model can affect the spatial thinking skills possessed by students, even though both experimental classes received the GI model treatment. Further results indicate that the GI model can affect spatial thinking skills in terms of students geoliteracy. However, there is a significant difference in spatial thinking skills based on geoliteracy between students at SMAN 6 Malang and students at SMAN 5 Malang, even though both experimental classes received the GI model treatment.
