    This research aims to find out that remedy using application of Children Learning in Science (CLIS) learning model assisted with concept cartoon worksheet is effective to correct misconception of VIII class students of SMP Muhammadiyah 1 Pontianak on Archimedes Law material. Research sample involves 19 students of class VIII C. Research design used is pre-experimental design with one group pre-test post-test design form. Collecting data tool consists of 9 questions which represent 3 Archimedes Law concept. According to the answer analysis of pre-test and post-test, the decline in number of students who have misconception before and after the remedy for each concept is averagely 64%, the decline of each student's misconception before and after the remedy is 57%. The remedy using application of CLIS learning model assisted with concept cartoon worksheet is effective to decline the misconception students have, so it is expected to become one of learning model alternative in learning physic

    This research aims to improve the mathematical communication ability of students on algebraic material in seventh grade of SMP Kemala Bhayangkari 1 Kubu Raya. This form of research is the pre-experiments with the design of One-group pretest-posttest design. The sample of this research was 30 students of class VII A. The sample is determined by simple random sampling technique. From the analysis of the data obtained, the students average pretest score is 16,11 while the students average posttest score is 41,39. The results of gain scores obtained an average gain index of 0.30, meaning that there is an increase in students\u27 mathematical communication abilities after learning through Realistic Mathematics Education approach to the medium category. Student response analysis results using Likert scale calculations indicate that the students gave positive response towards learning mathematics through realistic mathematics education approach

    This classroom action research aimed to improve students' outcomes and motivation in the static fluid material through quantum teaching model. This research was conducted in two cycles to the eleventh grade of natural science major 2 (XIIPA 2) of Public Senior High School 9 Pontianak with a total of 31 students. The data were collected through the learning outcome test, learning motivation questionnaire and learning observation sheet. The results indicated that there was an improvement in students' learning outcomes from the first to the second cycle by 3,22% from 70,97% to 74,19%, while the improvement in students' learning motivation from the first to the second cycle was 2,10% from 75,40% to 77,40%. Based on the research findings, it was concluded that the quantum teaching model could improve the students' learning outcomes and motivation particularly in the static fluid material. The application of this model should be designed with the best learning media preparation so as to increase students' interest in the material

    A survey to determined weaning weight, repeatability, and MPPA using 60 Ettawah Crossbreeddoe were held on Kelompok Tani Margarini, Sungai Langka Village, Gedong Tatanan SubDistrict, Pesawaran Regency. Data were taken from first and second offspring record onDecember 23rd, 2012, to January 17th, 2013.The corrected weaning weight, repeatibility, and MPPA resulted, i.e: 21,58 ± 1,03 kg; 0,31; and21,58 ± 0,49 kg, respectively. The best 5 MPPA were showed by doe number P1 (22,41 kg); G1(22,34 kg); B2 (33,232 kg); P2 (22,27 kg); and F1 (22,25 kg). The result also showed that 50% ofdoe have higher MPPA than that of the average

    Get PDF
    Penelitian ini bertujuan untuk mengetahui persentase bungkil kacang tanah terbaik yang dapat memberikan nilai laju pertumbuhan dan efisiensi pakan tertinggi pada ikan nila. Penelitian dilaksanakan dari bulan April sampai dengan bulan Mei 2015 di Laboratorium Akuakultur Gedung 4 Fakultas Perikanan dan Ilmu Kelautan Universitas Padjadjaran. Metode yang digunakan dalam penelitian ini adalah metode eksperimental Rancangan Acak Lengkap (RAL) dengan lima perlakuan dan tiga ulangan. Pakan diformulasikan pada persentase penggunaan 0%, 5%, 10%, 15% dan 20%. Parameter yang diamati adalah tingkat kelangsungan hidup, laju pertumbuhan harian, efisiensi pakan dan kualitas air. Hasil penelitian menunjukkan bahwa penggunaan bungkil kacang tanah dalam pakan dapat digunakan hingga taraf 20% dengan nilai laju pertumbuhan yang terbaik yaitu 0,7% dan efisiensi pakan 16,76%

    Makrozoobenthos sebagai Bioindikator Kualitas Air Sungai di Sub DAS Ciliwung Hulu

    Macrozoobenthos has a relatively sedentary nature and the very limited movement which will directly affected in the event of changes in water quality, therefore markozoobenthos often used as bio-indicators of water quality. This research was conducted form March to June 2015 in the Ciseuseupan sub watershed, Cisukabirus sub watershed and Cisuren sub watershed with the purpose of determining level of water quality and influence of land-use on the quality water by using macrozoobenthos community structure. Biological indices were used to analyze the macrozoobenthos are FBI and SIGNAL2. FBI values in the Ciseseupan sub watershed are 5,02 with criteria the quality of water moderate, in Cisukabirus sub watershed are 3,96 with criteria the quality of water very good and in Cisuren sub watershed 4,37 with criteria the quality of water good. Extensive use of forest land larger than the residential land use in Cisukabirus sub watershed were the major factor in the high quality in the sub watershe
