Studies of correlations between students’ beliefs and various aspects of student learning become one of the fastest growing research areas in the field of education and psychology. The aim of the current research was to analyze the correlations between learning environments, students' beliefs, and self-regulation in learning physics through structural equation modeling (SEM). There were 1010 students from the existing five public high schools in Jambi city, Indonesia, participating in the research. Three self-report questionnaires including (1) WIHIC, (2) CLASS, and (3) MSLQ were used to collect the research data. The data analysis showed that students’ beliefs were significantly and positively correlated with multiple dimension of self-regulation in learning physics (critical thinking and peer learning); while the dimension of sense-making and problem-solving ability significantly related to the affective component of self-regulation (test anxiety). However, the dimension of students’ beliefs did not have any significant effect on all of the self-regulation components. Additionally, learning environment dimensions were significantly related to students’ beliefs about physics on the dimension of conceptual connection and related to all of the self-regulation dimensions. Keywords: learning environment, self-regulation, students' beliefs, structural equation modeling.

Purpose of the study: The purpose of this research is to know the science process skill and motivation of the basic science process from Physics education student. Methodology: The research design used in this study is the Associative Quantitative research method with a correlational research design. In the research using technique sampling used is Purposive Sampling. The instruments of data collection used are questionnaires motivation and observation sheet Sains Process Skills. Measurement of students' science process skill is done when students perform Basic Physics I practice on density topic. The criteria that researchers set were physics education students who had contracted basic physics courses. Main Findings: The result of the research stated that the basic science process skill of physics education student as a whole is not good because of lack of experience in doing a practicum and their understanding of lab topics. Applications of this study: When someone is highly motivated, they will not experience difficulties in mastering their science process skills and so if someone has low motivation, they will experience difficulties in their process skills. Novelty/Originality of this study: The renewal that is seen is whether there is motivation in the science process skills. There is motivation in student learning processes, one of the results is process skills. Process skills are the result of learning from these students. Because science process skills emphasize the learning process, accreditation, creativity, values ​​and also the attitude of a student who will later be applied in daily life. Therefore we can say that science process skills have a relationship with the motivation of a student.

This article presents researches conducted at Muaro Jambi high School 5, at Muaro Jambi High School 10, at Jambi City High School 5 and Jambi City High School 10 about the relationship between students' attitudes and learning styles and students' motivations towards physics subject. It can be concluded that attitude indicators, namely is an inquiry attitude indicators in physics have good criteria, attitude adoption indicators scientific has sufficient criteria and for indicators of interest in increasing the time to study has good criteria. Whereas the dominant learning style in the four schools studied was a visual learning style with a percentage of mastery of 46.7%. For students, learning motivation also has a high percentage of 41.4%. There is a relationship between learning styles and attitudes towards physics subjects at the significance of 0.44 and also there is a relationship between motivation and attitudes of students in the four schools studied.

The purpose of this study is to develop affective assessment of students in physics the form of interests students have using MySQL. There are 3 stages of the method used in this study, namely (1) Development, (2) Implementation, and (3) Evaluation. The subjects involved in this study were 265 students from Batanghari High School with 265 students using purposive sampling techniques. The results of this study are that the validator gives good results regarding the assessment of e-interest in the category given which is very feasible and obtained valid statements of 25 statements with a reliability value of 0.870. Then students' interest in physics dominated both categories was 54.4%. Student responses when using the e-interest assessment received a good response seen from the attitude of students, who were happy, excited and had a high curiosity towards this E-Assessment. It can be concluded that the e-interest assessment needs to be developed on a large scale.

This study aims to determine differences in mastery of process skills science student physics and chemistry education study programs both in the experimental class and control class. The experimental class uses a science process skill-based guide with the inquiry model, while the control class uses conventional guidance. This research is a quantitative type of experimental research with a group comparison design static. The research sample was 201 students. Observations are made by using the observation sheet instrument. The results of this study indicate that there are differences in the mastery of science process skills between students using an inquiry model practicum guide and students who use conventional practicum manuals in each study program. Based on the results of hypothesis testing using an independent sample t-test at a significance level of 5%, a significance value of 0.000 was obtained in the study program physics and chemistry education. Where based on statistical parameters used it can be concluded that the mastery of science process skills in the experimental class is better than the mastery of science process skills in the control class.

Retinal diseases are a visual disorder that can cause human vision problems, such as blindness and low vision. Early detection of this disease is important to prevent visual impairment. In ophthalmology, segmentation of blood vessels is a major component of color retinal fundus images analysis for monitoring and diagnosing retinal diseases, like diabetic retinopathy, hypertensive retinopathy, age-related macular degeneration and arteriosclerotic. This process is effective to identify retinal diseases more accurately. This paper using Gaussian Filter to segmenting blood vessel on retinal images because this method is effective to remove noise and make blood vessels on images more clearly. These methods are applied to color fundus images from DRIVE database. These databases contain color fundus image are used to evaluate this method. The performance is evaluated by accuracy, sensitivity and specificity. The proposed method has the average of accuracy, sensitivity and specificity at 95.72%, 96.90% and 82.10%.

The first-grade students of SMP Negeri 9 in Jambi City experience difficulties in understanding science concepts, especially temperature and heat. Their ability to process numbers has also not been optimally developed. There is a need for teaching materials in the form of a learning module that is easily accessible for students to learn independently and better. This study aims to produce a product in the way of guided inquiry-based electronic learning modules to contain instructional materials and learning media that are easy to use and contextual, with a clear and understandable language and delivery. The development model used is the ADDIE model. The study result has been analyzed using the descriptive qualitative method. The development process has been carried out a prototype electronic learning modules with a science literacy load on the learning material presented. The individual test results and small group trials show that the electronic learning module is easy to use and easy to understand with an attractive design. Furthermore, the electronic learning module has a positive impact on improving learning and reading motivation and the ability to process numbers. It is an electronic module that potentially enhances students’ science literacy.
