This study aims to obtain information regarding the effect of the RPO on students' scientific literacy using global scientific literacy questionnaire (GSLQ) in terms of GSLQ dimension and gender differences. The quantitative research approach is used with experimental methods. The U Mann Whitney, Wilcoxon, T-Test, and descriptive statistics were used to determine whether there were differences in students' global scientific literacy between the control group and the experiment group. The results show that there are no significant differences in students' global scientific literacy between the control and experiment groups, nevertheless, the results in the experiment group show that RPO appears to have significant effects, especially in the habits of mind dimension and across students' gender. Male students in the experiment group are able to show better results on habits of mind dimension than female students. However, female students in the experiment group are able to show a higher increase than the students in the control group.

IntisariKajian ini bertujuan untuk mengetahui pengaruh variasi temperatur annealing dan holding time (waktu tahan) terhadap struktur kristal, ukuran partikel, dan ukuran butir lapisan tipis BaZr0,15Ti0,85O3. Penumbuhan lapisan tipis menggunakan metode Chemical Solution Deposition (CSD) atau Sol Gel di atas substrat Pt/Si dengan spin coater. Proses Sol Gel meliputi persiapan sol (koloid), gelation dari sol, dan penguraian pelarut. Penumbuhan lapisan tipis menggunakan variasi temperatur annealing 800 dan 900• C, dan variasi holding time 3 dan 4 jam dengan kecepatan putar 4000 rpm. Lapisan tipis dikarakterisasi dengan XRD dan dilakukan penghalusan menggunakan metode Rietveld dengan program GSAS. Ukuran partikel didapat dengan formula Scherer serta alat SEM untuk mengetahui ukuran butir. Berdasarkan hasil analisis didapatkan bahwa variasi temperatur annealing dan holding time mempengaruhi struktur kristal, ukuran partikel, dan ukuran butir lapisan tipis. Bertambahnya temperatur annealing dan holding time maka parameter kisi semakin besar dengan a = b = c yang berarti memiliki struktur kristal tertragonal. Ukuran partikel semakin besar seiring dengan bertambahnya temperatur annealing dan holding time. Namun, ukuran butir tidak berpengaruh terhadap penambahan temperatur annealing. ABSTRACTThis study purpose to determine the effect of variations of annealing temperature and holding time of the crystal structure, particle size, and grain size on BaZr0,15Ti0,85O3 thin films. Growth of BaZr0,15Ti0,85O3 thin filmsused Chemical Solution Deposition method (CSD) or Sol Gel on the substrate Pt/ Si were prepared by spin coater. These steps the preparation of CSD include sol (colloidal), gelation of the sol, and removal solvent. Growth of thin films using variation of the annealing temperature 800 and 900• CC, and variation of holding time 3 and 4 hours with a rotational speed of 4000 rpm. Thinfilmshave been made then characterized by XRD and refinement performed using the Rietveld method by the GSAS program for to determine the crystal structure. The particle size obtained by Scherer formula and SEM tool to determine the grain size. Based on the analysis it can be concluded that the variation of the annealing temperature and holding time affects the crystal structure, particle size and grain size of the BaZr0,15Ti0,85O3.thinfilm With increasing annealing temperature and holding time the greater the lattice parameters and a = b = c which means it havetertragonal crystalline structure. Particle size greater along with increasing annealing temperature and holding time. However, the annealing temperature variations for the grain size can not be determined.

This study aims to develop affective assessment instruments for practical assistants in physics laboratories. The development model used Plomp development model, consisting of five stages, namely: (1) the initial investigation stage; (2) Design; (3) Realization / construction stage; (4) testing, evaluation and revision; (5) implementation. The questionnaire is prepared based on theory and proven by its relevance (content validation) by experts. Collecting data in this study using non-test data collection techniques in the form of affective / attitude questionnaires. The affective score obtained will be analyzed the validity of the instrument construct using the analysis rash model theory with the winsteps program. Reliability using Alpha Cronbach. The attitude instrument was designed with reference to the criteria and indicators based on Rao's theory. Content validity by 7 experts showed that all items had good validity. The inter rater reliability of the questions was 0.8. Empirical validity shows that all items are valid. The instrument has item reliability 0.93 and person reliability 0.39 with good and moderate categories. This shows that the consistency of the answers from the subject is still weak, but the quality of the items in the instrument's reliability aspect is quite good. The instrument that has been developed meets the criteria of validity and reliability.
