This study aims to determine: (1) Is there a difference in influence between the Problem based learning and Discovery learning models on student learning outcomes (2) Are there differences in influence between students with high initial ability and low initial ability towards learning outcomes (3) Are there interactions between the Problem based learning and Discovery learning learning models with initial abilities towards learning outcomes? This study aims to examine the comparative learning model of problem based learning and discovery learning towards learning outcomes in terms of ability early.This study used an experimental method with the only group posttest design and factorial design with population of the whole MIPA class XI and sampling using purposive sampling, the selected sample was XI-MIPA 1 and XI MIPA 4. The instrument used was an initial ability test and a learning achievement test. The results of this study indicate that: (1) There is a significant difference in influence between problem based learning and discovery learning models on learning outcomes with a value of sig * 0,000 which means

The use of student's worksheets in biology physics lectures will contribute to optimizing the achievement of learning objectives in conveying material from lecturers to students and the achievement of scientific literacy skills to students. This article aims to describe the validation of student worksheets in Biology Physics courses to improve student scientific literacy. Development research was carried out in the Lambung Mangkurat University Physics Education Study Program 2019/2020. Validation is one of the processes at the part of the development stage. The validity of student's worksheets is measured using a validation sheet and then determined based on validation by experts which are stated as Valid or invalid. If valid, it will be categorized again as very good, good, enough, less, and not very good. The conclusion of this article is the Student Worksheet for increasing scientific literacy in Physics Biology courses is valid in both categories. Thus this Worksheet can be implemented for further testing at the dissemination stage.

This research is a Pre-experimental research with One Group Pretest-Posttest Design. This study aims to describe the students 'problem solving abilities during the learning process and determine the effect of CCM CCA learning models on problem solving skills and mastery of students' static fluid concepts. The study population was all students of class XI MIPA SMAN 4 Praya with a sampling technique using purposive sampling. The research sample was students in the three classes that were used as experimental classes that were given treatment in the form of learning using the CCM CCA learning model. Problem solving skills are obtained during the learning process by using LKPD which is equipped with problem solving ability instruments. The instrument used for problem-solving abilities uses test instruments in the form of test descriptions. Problem solving ability is measured by problem description. The conclusions obtained, namely 1) the level of problem-solving ability when the learning process is included in the medium category, 2) the CCM CCA learning model influences the ability of problem solving and mastery of students' static fluid concepts.

Research has been conducted which aims to determine the distribution of rocks containing iron ore using the geomagnetic method in the North Pringgabaya Village, East Lombok Regency, NTB. Retrieval of magnetic data was carried out with the Proton Precision Magnetometer (PPM) GEM-19T v7.0 in an area of 4 km2 with a measurement point spacing of 100 m and spacing between trajectories of 200 m. From the measurement data, daily and IGRF corrections were performed to obtain total magnetic anomaly contours. Upward continuation is carried out to separate regional and residual magnetic anomalies at an altitude of 200 m. The results showed that there were indications of iron ore in the area with magnetic anomaly data ranging from -147.6 nT to 594.8 nT. The results showed that the rocks identified as iron ore were sand which were mostly found in the eastern and western parts of the study area with a susceptibility value of 0.01634885 SI up to 0.02674884 SI at a depth of 153 m to 449 m..

This study aims to produce interactive physics learning media based on macromedia flash 8 straight motion material for Class VII Students of SMP / MTs. This type of research uses the Research and Depelopment (R&D) approach by adopting the ADDIE (Analyze, Design, Depelopment, Implementation, and Evaluation) development model. Design the learning media trial using the Post-Test Only Control Group Design. Data collection instruments in the form of material expert evaluation questionnaire, media expert evaluation questionnaire, science subject teacher evaluation questionnaire, student response questionnaire, multiple choice tests and student learning activity questionnaire, data collection techniques namely test techniques and observation techniques. Data analysis techniques are media feasibility test, normality test, variance homogeneity test and hypothesis test. The results of the study of the feasibility aspects of instructional media, media experts declared worthy of an actual score of 75, material experts declared worthy of an actual score of 73, the subjects of Natural Sciences stated worthy of an actual score of 66, and the average score of actual responses of 4 students was 58.25 . While the results of research on the aspect of learning media testing showed that interactive physics learning media based on macromedia flash 8 was effective on student learning outcomes with an average experimental class score of 70.38 and classical learning completeness of 71.42%. The percentage of active students in the good category with a percentage of 69.09%. When compared with the control class with an average value of 50.37 and classical learning completeness 22.22%. The percentage of active students in the category is sufficient with a percentage of 41.82%.

The effect of software tracker on learning coefficient restitution based inquiry guided on ability of multiple representations. Software tracker in learning the restitution coefficient can help to track the motion of objects at a more precise and accurate time, helping students get the track of objects that based on these tracks students can be guided to find concepts or equations of object motion. This study aims to describe how the influence of usingatrackeronguided inquiry based restitution coefficient learning on the ability of multiple representations ( MR ). The population of this research is all grade X students of Muhammadiyah 1 Purbolinggo Senior High School. The sample of thisresearch is students of gradeX MIPA 2 Muhammadiyah 1Purbolinggo Senior High School. The research design used is the One Group Pretest-Post testDesign.Learningis done by practicing guided inquiry of restitutioncoefficien practicum activities,then processing the experimental data byanalyzing the experimental video using a software of tracker. Ability MR of students is obtained from the learning process in the formofpretestand posttest. Analisis data is done using Paired Sample T-Test. Based on the results of the study obtained an average score of ability MR has increasedby 58,64 % with an average N-Gain in the medium category (0,68 ).
