Abstract

ABSTRACT. North Sulawesi is an area that has the potential for geothermal energy sources, characterized by the manifestation of hot springs, active volcanoes with temperatures ranging from 80-200 0C, one of which is in the eastern crater of Mount Amabang and the geothermal area of Lahendong. This research was conducted to calculate and determine the amount of natural heat loss (Heatloss) and electricity reserves from the manifestation of hot springs in the eastern crater of the threshold volcano and Lahendong geothermal area, also to find out the similarities and differences of these manifestations. The method used is direct observation and measurement in the field by measuring the parameters needed in this study. Based on the results of the study, the large natural heat dissipation from the manifestation of hot springs in the eastern crater of the threshold volcano by 0.1047 MW and the geothermal area of Lahendong by 0.0690 MW with electricity reserves in the eastern crater of the threshold mountain by 1,047 MW and the Geothermal Lahendong area amounting to 0.690 MW. Keywords: Threshold, Lahendong, heat loss, electricity.

Abstract

ABSTRACT. Research in the background by the lack of interest in student learning. The purpose of this study was conducted to determine the effect of problem based learning models with experimental methods on student learning outcomes. This study uses an experimental method, the population taken from all class X, which consists of science and social classes at Advent Klabat Manado High School, while the sample taken is 1 class as a subject class that is class X science consisting of 24 students. The date analysis technique used is descriptive technique with the assessment of PBL, attitude, psychomotor and is taken and collected from the assessment of the learning process and the results of the pretest and posttest on the material of Sight Sight and Optical Devices. Analysis of the results of this study shows that the application of PBL learning models using experimental methods in the Sense of Sight material and Optical Devices can improve student learning outcomes.Keywords : Learning Outcomes, Sense of Sight, Optical Devices, Problem Based Learning
