Kekayaan alam Indonesia harus dijaga keberadaannya sebagai sumber kehidupan manusia. Tetapi saat ini banyak terjadi kerusakan lingkungan hidup di Indonesia akibat ulah manusia. Lingkungan hidup yang memberikan penghidupan justru menjadi ancaman untuk masyarakat karena kerusakannya. Beberapa kelompok masyarakat daerah ada yang terus berupaya menjaga lingkungan hidup mereka, salah satunya melalui kearifan lokal. Penelitian ini bertujuan untuk mengetahui bagaimana dampak kearifan lokal Ruwat Petirtaan Jolotundo pada kelestarian lingkungan hidup di sekitarnya. Penelitian ini menggunakan pendekatan kualitatif dengan teknik wawancara mendalam, observasi partisipasi, dan dokumentasi. Penelitian ini dilaksanakan di Desa Seloliman Kecamatan Trawas Kabupaten Mojokerto. Penelitian dilaksanakan selama  6 bulan, diawali dari persiapan, studi pendahuluan, wawancara, observasi serta mengikuti kegiatan Ruwat, hingga pengolahan dan analisis data. Hasil penelitian menunjukkan bahwa Ruwat Petirtaan Jolotundo memberikan dampak yang baik terhadap kelestarian sumber air, flora dan fauna di kawasan Jolotundo. Sumber air sangat terjaga kuantitas dan kualitasnya, tumbuhan pinus, mahoni, sengon, jati dan fauna seperti kera,anjing liar, dan babi hutan (celeng) dengan mudah dapat ditemukan. Ruwat Jolotundo mampu menyadarkan masyarakat akan pentingnya menjaga lingkungan. Kearifan lokal ini harus dijaga dan diturunkan kepada anak cucu sebagai penerus bangsa agar lingkungan kita tetap terjaga. Penelitian ini dapat dikembangkan pada tema urgensi Ruwat atau kearifan lokal sebagai alternatif menjaga lingkungan hidup.

There are no specific teaching materials that accommodate student learning needs, and learning materials are still scattered in various sources. This condition occurs in the Geography of Disaster course, which so far there is no teaching material. Therefore, it is necessary to study textbooks for the Geography of Disaster as an alternative to find a way out in overcoming and making it easier for students to study these subjects, the purpose of this research and development is to "develop teaching materials for the Geography of Disasters based on experience to improve student learning competencies". This research is a development research. This study aims to develop and produce learning materials in the form of textbooks for teaching and learning strategies courses, especially on the subject of cooperative learning strategies. The development of constructivist learning tools assisted by textbooks with the 4-D model is quite effective in increasing student motivation and participation to be actively involved in the learning process compared to conventional learning. As many as 86.75% of students are actively involved in cooperative learning assisted by textbooks while in conventional learning the activeness of students is 63.25%.

This study aims to analyze the effect of the TASC learning model on students' ability to solve problems in natural resource management material. This study uses an experimental method with the design of Non-equivalent Pretest-Postest Control Group Design. The results of this study indicate that the TASC learning model has an effect on students' problem solving abilities in natural resource management materials, where experimental class students who use the TASC learning model have better problem solving skills than the control class that uses the class discussion model. in natural resource management material. Based on the results of hypothesis testing, it was concluded that there were significant differences between students learning using the TASC learning model (Active Thinking in Social Context) with students learning to use cooperative type class discussion learning models to solve problems.

Understanding geomorphological characteristics must provide morphographic, morphometric,morphogenetic, and morphochronological information. This study aims to identify geomorphological characteristics in the Prambanan hills area compiled in the form of a geomorphological map. The research is based on maps, previous research reports, and field observations in the form of field checks on theelements studied. The geomorphological mapping system used is the ITC system. The main analysis in this research is spatial analysis in the form of overlapping spatial data. The relationship between landform units,lithology, and slopes is information that is analyzed descriptively. The results showed that on a map with a scale of 1: 30,000, 9 geomorphological units could be identified. The 9 geomorphological units are a combination of morphometry, genetics, and lithology. The combination consists of 2 landforms, namelytraditional and structural hills, and slopes; The lithology consists of 3 layers, namely the Lapili Formation of Semilir, Sand Formation of Kebo Butak, and Tuff Formation of Semilir. While the morphometry is in theform of slope units, namely 8-15%, 15-25%, 25-45%, and >45%. While the age based on lithology is Late Oligocene – Early Miocene in the Kebo Butak Formation and Early Miocene – Middle Miocene in theSemilir Formation.
