KARAKTERISASI IMPEDANSI LAPISAN TIPIS ZnS:Mn YANG DIBUAT DENGAN CO-EVAPORASI ZnS DAN Mn

The aim of this research is to characterize impedance, capasitance and relative permitivity of the characteristics of electric thin film ZnS and ZnS:Mn. This research was started from making thin film with different deposition speed and with thermal co-evaporation method in vakum tubes.  The estimation is the characteristics of thin film ZnS impedance and ZnS:Mn was done outside this vacum with various frequency between thousaund to million hertzs, with different deposition speed and the same thickness. Defining impedance of ZnS thin film wich the most optimal frequency would influence capasitance and relative permittivity of the thin film on the characteristics of the electricity. Besides, capasitance and resitance values of ZnS:Mn thin film would change if given different Mn portion on that thin film. From the result of the research, it could be identified as follows. On the area of the thousand to ten thousand Hertz, it was know is that relative permitivity/constante static dielectrics K(0) ZnS:Mn thin film was not the frequency function that it could be regarded as constant like K(o) = 10. The price of capasitance ZnS:Mn was increasing with less Mn amount in that thin film. The price of ZnS:Mn electric resitance is reduced with less Mn amount on  that thin film. Key words: Impedance, thin film ZnS:Mn, co-evaporation

Remediasi Kesulitan Belajar Siswa Kelas XII IPA Man 1 Pontianak Pada Materi Dinamika Rotasi Menggunakan Model Learning Cycle 5e

The purpose of this research is finding out the effectiveness of learning cycle 5Es model in remediating learning difficulties faced by grade XII science students in MAN 1 Pontianak on rotational dynamics material. The method of research is Pre Experimental Design with One Group Pretest Posttest Design. The data was taken from the students in grade XII science class, which are chosen by using intact group. Multiple choices used to find out students difficulties in understanding concept and essay used to find out students difficulties in solving the question. Students difficulties of understanding concept was decreased by 24, 11% and in solving question was decreased by 57, 59% after remediation. Learning cycle 5Es model is effective to remediate the students\u27 learning difficulties in the rotational dynamics material with the average price of the proportion of the number of errors students in understanding the concept of 0.325 (moderate) and in solving problem proportion of 0,81 (high). This research is expected to be used as an alternative in remediation activity for the students in order to solve students learning difficulties

Integrasi Scramble dalam Pembelajaran Ulang Meremediasi Kesulitan Belajar Siswa Kelas VIII Materi Hukum Newton

This study is aimed to determine the effect of remediation by re-using the learning methods of scramble to lower the students' learning difficulties on class VIII K Immanuel II junior high school for Newton's law. It uses Pre-Experimental Design, which formed as One Group Pretest-Posttest Design with a total of 33 participants VIIIA class by selected intact group. The data collection tools used such as: Multiple-choice diagnostic tests to determine the average decline in the students' learning difficulties and the student interest questionnaire in a closed questionnaire to find a large increase in the student interest. Pretest and posttest results show a decline in the average percentage of students' learning difficulties each concepts by 5.90% and the average decrease in the percentage of students' learning difficulties by 9.78%. Wilcoxon test results show that there are differences between the students' learning difficulties while the remediation using scramble has been given and after in a re-learning method (Z count (2.43)> Z table value (1.96)) with the level of effectiveness about 0.3 (relatively low).The improvement of student interest are moderate ((g) = 0,37)
