Abstract

Papandayan is an A-type active volcano located in the southern part of Garut Regency, about 70 km southeast of Bandung, Indonesia. Its earliest recorded eruption, and most violent and devastating outburst occurred in 1772 and the latest eruptions occurred in the period of 11 November to 8 December 2002, and consisted of freatic, freatomagmatic and magmatic types of eruption.During the latest eruption period, GPS surveys were conducted at several points inside and around the crater in a radial mode using the reference point located at Papandayan observatory around 10 km from the crater. At the points closest to the erupting craters, GPS displacements up to a few dm were detected, whereas at the points outside the crater, the displacements were in the cm level. The magnitude of displacements observed at each point also show a temporal variation according to the eruption characteristics. The results show that deformation during eruption tends to be local, e.g. just around the crater. Pressure source is difficult to be properly modeled from GPS results, due to limited GPS data available and differences in topography, geological structure and/or rheology related to each GPS station.

Abstract

This study aims to explore cognitive assessment techniques based on teaching experience. The method in this study uses a descriptive survey with data collection techniques using purposive sampling of tutors who have taught at PKBM for 5 years. The population in this study were PKBM (Pusat Kegiatan Masyarakat or Community Learning Center) tutors in Jakarta at Package A, Package B, and Package C, namely 158 tutors with details as follows; Package A 45 tutors, Package B 53 Tutors, and Package C 60 tutors. Data collection was done by using question forms and data analysis used descriptive translation to obtain an average frequency of learning assessment techniques. The statistical analysis used Confirmatory Factor Analysis, so that it can be seen directly and indirectly. The results showed that the dominant assessment technique used in non-formal science tutors was a written test that averaged 32 times in one semester. A group of tutors with 5 to 10 years of teaching experience using a variety of assessment techniques. Descriptively, it can be said that the use of the frequency spectrum of cognitive assessment techniques is coupled with experienced tutors with a tendency in written tests. In this study, the results show that the preparation of assessment in non-formal education there is an influence between the preparation of the assessment of the implementation of the assessment. So it is necessary to improve tutor assessment preparation.

Abstract

In environmental education, there have been many studies on learning multimedia, but the media used tends to be limited to the use of conventional media. In this study, we investigate the feasibility of Kamiholo, a combination between hologram and Kamishibai for environmental education in elementary school to improve the students' learning outcomes. To avoid bias and increase objectivity, the learning outcomes of Kamiholo utilization will be compared with those of conventional Kamishibai utilization. The experiments in the control and experimental groups both show good results. However, there is a significant difference in the improvement of the student achievement when learning using Kamiholo based on the N-Gain, where the N-Gain value of Kamiholo and Kamishibai are 0.69 and 0.49, respectively. Overall, we have successfully demonstrated the advantages of our new multimedia by combining holograms and Kamishibai for environmental education.
