Full text linkThe reasons of this research is to determine the results of a study about the ability of DESCA and self concept new students of Mathematics Education in the course geometry. The method which used in this research is descriptive analysis method. Subjects in this research are students of mathematics education 2014 which take a course of Geometry I in Faculty of Education at the University of Tanjungpura Pontianak. The results showed that among the five aspects of DESCA which gives a good change is the aspect of self-concept. So, it makes the increase of student's self-concept , such as the confidence to expression their ideas and the courage to self recognition and expression of self-concept in geometry classes. Other conditions which conducive to implementation is the correct or incorrect answer is not broken immediately, but for accommodated and analyzed together. Keywords: DESCA, self concept, optimizin
PENERAPAN STRATEGI PEMBELAJARAN MOTIVASIONAL DENGAN PERMAINAN KARTU BERTEMA PROTISTA PADA SISWA KELAS X SMA
Full text linkThis research is motivated tendency in the field of biology shows that learning outcomes in protists material has not achieved the expected results. This is because teachers are more active than the students, so that the learning-oriented teacher (teacher-oriented) whereas passive during the learning of their students as well as the presentation of learning materials in the classroom is still conventional. This type of research is Classroom Action Research (PTK). Data taken using test instruments, observation sheet and test evaluation of learning outcomes is a means of collecting qualitative data processed. The results showed that by application of learning strategy discovery learning using protists themed card game can improve motivation and results of students of class X MIA1 SMA 4 PontianakKeywords : Motivation, learning outcomes, card game, Discovery Learnin
PENINGKATAN AKTIVITAS DAN HASIL BELAJAR MAHASISWA PADA MATA KULIAH ANATOMI TUMBUHAN MELALUI MODEL PEMBELAJARAN KOMPARASI YANG BERBASIS LESSON STUDY
Full text linkThis study aims to improve the activity and results of student learning in the subject of Anatomy Plant through a comparative study model based lesson study. The method used is classroom action research with 4 cycles. Samples used in this study is the third semester students of regular education courses Biology FKIP Veteran Bangun Nusantara University Sukoharjo force 2012/2013 as many as 24 people. The study began in November 2013 and April 2014. The learning activities were observed in the form of discussion and presentation activities, while learning outcomes measured were the post-test results after completion of the learning process of each cycle. Data analysis techniques with comparative descriptive, comparing the results of learning and learning activity cycle with the cycle I to IV. From the results of this study concluded that the average post-test or study results from Cycle I to IV increased starting 3.47, 3.72, 3.73 and 3.85, though in terms of learning activities is still not satisfactory because it only categorized quite active for the first cycle to the active cycle III and cycle IV.

DESAIN PRIMER PCR SECARA IN SILICO UNTUK AMPLIFIKASI GEN COI PADA KUPU-KUPU Papilio ulysses Linnaeus DARI PULAU BACAN
Full text linkThe insillico research was conducted to produce primer sequence of COI gene in Butterfly species Papilio ulyses from Bacan Island that will be used in gene isolation. The COI sub-unit I is a barcode gene that generally have special purposes in animal identification. It is also available in phyilogenetic analysis. The first step of method is downloading the COI DNA sequence of Papilio ulysses from GeneBank (NCBI). Then the conserve region of COI sequence is identified to determine primer. Primer is designed with primer designer software (Genamics Expression) in two direction of DNA reading frame that are : forward primer (COI Pu-F) and reverse primer (COI Pu-R). The last step is primer confirmation with primer blast tool in NCBI. Primers of COI gene that are produced consist of two, that are CGAAAATGACTTTATTCAACA for forward primer (COI Pu-R) and AGCAGTAATTCCAACAGCTC for reverse primer (COI Pu-R). The optimal temperature of annealing is from 50,740 to 55,740 Celsius with PCR product around 567 base pair long. Key Words : PCR primer, in silico, COI gene, Papilio ulysses, Bacan island
KARAKTERISASI IMPEDANSI LAPISAN TIPIS ZnS:Mn YANG DIBUAT DENGAN CO-EVAPORASI ZnS DAN Mn
Full text linkThe 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
