Abstract:
West Papua province has a geothermal resource that can be established as renewable electricity energy or tourism. One of the locations for geothermal prospects is in the Momiwaren district of South Manokwari regency. A preliminary study in form of a qualitative interpretation has been conducted through the analysis of high-resolution of earth gravity fields from the Global Gravity Map developed by Curtin University, Australia. This research was performed to increase the boundary of the geological structure which indicates the existence of a source of manifestation of hotsprings and the fault structures that control it. The study begins with the reduction of the gravity field data to obtain a complete Bouguer anomaly based on the SRTM2gravity terrain model correction. Furthermore, regional and residual gravity anomalies are separated, and vertical and horizontal gravitational gradient analysis using 2-D fast Fourier transform. Qualitative interpretation produces models and boundaries of the main structure and the corresponding Demini and Gaya Baru faults and the distribution of the geological rock formations in the study area. This interpretation provides useful information as a constraint for quantitative interpretation through subsurface inversion modeling to obtain detailed geothermal models in Momiwaren.

Abstract:
This study aims to determine the proportion of students' level of critical thinking skills on the subject of Impulse and Momentum, any difficulties experienced by students to reach the level of critical thinking skills, and solutions to overcome the difficulties of students achieving critical thinking skills. This research uses descriptive qualitative research methods. The subjects of this study were 27 students taken by purposive sampling technique. Data collection techniques in this study are tests of critical thinking skills, interviews, and observation. Data analysis techniques using descriptive statistics. The results showed that each student's ability, high ability students 36.84%, medium ability 34.50%, low ability 22.80% divided into two categories of KBK 2 with a percentage of 52.63% and KBK 1 with a percentage of 23, 94%. From the results of the study also obtained the achievement of students every KBK indicator. Student achievement in the Interpretation indicator of 51.58% Analysis 18.75% Evaluation 13.87% Inference 31.48% Explication 14.19% and Self Regulation 26.85%. So KBK students as a whole are in the low category with a percentage of 31.38%. The cause of students 'difficulties in fulfilling CBC indicators is the limited ability of students to formulate and find other alternatives, the completion of students' answers is difficult to draw conclusions and connect substance between materials, and has not been studied in depth so students tend to be careless in solving problems. The solution that can be used is to provide more experience to students in terms of critical thinking skills and additional learning outside school hours.
