Abstract

Physics is one of the subjects considered heavy and avoided by some students, which is very challenging, frustrating, perseverance, perseverance, thoroughness and lots of practice so that in reality, not many students like physics. This study aims to determine the differences and the relationship between students' attitudes and self-efficacy in learning science. This type of research is quantitative with a comparative type. The number of respondents used as a sample is 74 students. The data collection technique used simple random sampling. The study results using the T-test showed significant differences in students' attitudes and self-efficacy in science lessons, both female and male students in grade 8A and grade 8B. The correlation test results between students' attitudes and self-efficacy towards science subjects in grade 8A showed that the second variable (attitude and self-efficacy) was related. Moreover, the correlation test results in class 8B showed that the two variables (attitude and self-efficacy) were related. The urgency of this research is that teachers can find out the differences in attitudes and self-efficacy between male and female students. Compared to previous research, the novelty of this study is to use Attitude and self-efficacy variables, with different indicators from previous studies.

Abstract

The purpose of this study was to determine the comparison of students' attitudes and self-efficacy based on gender, and to determine the relationship between students' attitudes and self-efficacy towards science subjects. This research uses quantitative research with survey method. The sample in this study was 74 students from SMPN 1 Muaro Jambi in Muaro Jambi district. The sampling technique used is purposive sampling. There are two instruments in this study, namely attitudes towards science and self-efficacy. The results of the T-test of student attitudes towards science subjects obtained were sig. (2-tailed) < 0.05, so there were differences in student attitudes towards science subjects, both female and male students in class VIII A and class VIII B. The results of the T-test of students' self-efficacy on science subjects obtained a value of sig.(2-tailed) < 0.05, so there are differences in student self-efficacy on science subjects, both female students and male students in class VIII A and class VIII B. While the results of the correlation test between attitudes and students' self-efficacy towards science subjects class VIII A and VIII B showed a value of sig. (2-tailed) < 0.05, then there was a relationship between students' attitudes and self-efficacy towards subjects’ science lessons, both female students and male students in class VIII A and class VIII B.

Abstract

The importance of students' interest in learning is learning skills, so research is carried out to assess students' interests and skills in depth based on grade level and gender in a school so that interests and skills can be known in depth based on the indicators tested. There has been no research that examines student interest and science process skills in detail based on grade level and generation in a school. So the autor make this study with purpose to analyze how the interest and science process skills between women and men compare in science subjects and to analyze how the relationship between students' interests and science process skills with science subjects. This study uses a quantitative method with a comparative type. Quantitative research is a field of inquiry that stands alone, is scientific in nature and aims to understand social reality. The instrument in this study used a questionnaire and an observation sheet, namely a student interest questionnaire and an observation sheet for science process skills. Based on the results of hypothesis testing, research testing and data analysis, the conclusion of this study is from the T-test there are differences in the interests of female students and male students in class VII A and VII B. From the results of the T test for students' science process skills there are differences in the interests of female students and male students in grades VII A and VII B. Based on the results of the correlation test between interests and science process skills of grade VII A students there is a relationship between interests and science process skills between female and male students as well as in class VII B. Students' interest and science process skills have a significant influence on curiosity, learning materials and teacher attitudes, student observation and communication.

Abstract

Tujuan penelitian untuk mensintesis nanokomposit dan mengkarakterisasi hidroksiapatit dari udang papai dan dikomposit untuk meningkatkan sifat mekanik tanpa mengubah biokompatibilitasnya. Komposit hidroksiapatit menggunakan bahan lain seperti alumina disintesis menggunakan metode hidrotermal dengan variasi konsentrasi 0,025; 0,05 dan 0,075 juta. Komposit HA/Al2O3 dikarakterisasi dengan FTIR, SEM, dan XRD. Hasil FTIR menunjukkan bilangan gelombang. HA/Al2O3 yang disintesis menunjukkan pita O-H yang khas pada kisaran bilangan gelombang 2361-3460cm-1. CO32- pada rentang bilangan gelombang 1380-1500 cm-1. Al-O pada rentang bilangan gelombang 901cm-1 menunjukkan bahwa HA telah didoping dengan Al2O3. PO43- pada bilangan gelombang 605;873 dan 1041 cm-1. Pola difraktogram menentukan bahwa semua puncak HA/Al2O3 yang diamati berada pada daerah 2theta 10-70° menurut database referensi dan derajat kristalinitas meningkat dengan konsentrasi tinggi alumina yang digunakan. Morfologi doping HA/Al2O3 berupa aglomerasi karena pada proses sintesis menggunakan metode hidrotermal tidak ada pengadukan sehingga bahan kurang homogen, analisis SEM menggunakan software origin dan image j menunjukkan presentase porositas lebih kecil sehingga memenuhi persyaratan untuk digunakan sebagai implan dan memberikan nilai ukuran semakin kecil dalam skala nano, yakni pada rentang 5-14,5 nm.
