Abstract

Ijen caldera complex is a volcano that has a 7 km diameter elliptical caldera which only leaving a northern caldera wall curving towards the southward. Ijen crater as a youngest volcano and still active today stratigraphically composed of lava flow, pyroclastic flow sediments, and pyroclastic fallout. Threats that arise if an eruption occur is pyroclastic flow, pyroclastic fallout, lava flow, lahar flow, and water of ijen crater. The existance of vulcanic activity of Ijen crater impact positively to the society which live around the Ijen mountain region. Their economy rest on sulphur mining and the soil fertility which is used to potato, cabbage and coffee crop cultivation. If this happen it could be a serious threat for the environment, include the population settled around volcano and along the river upstream in the lake of this crater and is a catastrophe. The disaster can be huge because water volume of large enough crater lake and very acidic, besides the result of explotion such as hot clouds, phreatic eruption in the form of lava eruption is also possible to happen.

Abstract

The difficulties experienced by pre-service social studies teachers in mastering the pedagogical competencies that are essential for quality education are the urgent background for conducting this study. This study analyzes the difficulties of pre-service social sciences teachers in mastering and designing pedagogical competence, which is the essence of teacher quality. Using a qualitative approach and in-depth interviews with 23 UNESA Social Science Education students, this study identified a significant gap between campus theory and field practice. The main difficulties include adjusting materials and methods to diverse student characteristics, limited media and innovative learning resources, selecting appropriate learning methods, classroom management, and compiling comprehensive assessments. The main causal factors are the lack of direct teaching experience, limited PLP time, lack of practical guidance from lecturers, and self-confidence issues. Although lectures have provided a strong theoretical foundation, this provision is not enough to face classroom reality. These findings emphasize that pedagogical competence is applicative and requires intensive practice. Closer integration between theory and practice, improving the quality, duration of PLP, and contextual guidance are needed. Thus, it is hoped that pre-service social sciences teachers can become adaptive, innovative, and effective educators, contributing to improving the quality of national education.
