Abstract

This study was aimed at estimating true metabolizable energy (TME) and crude protein (CP) intake of Kerinci Duck reared under scavenging system in Kerinci District, Province of Jambi. Twovillages (Koto Majidin [KM] and Semerap [SP]) were selected for the study where ducks were the most common livestock kept by farmers. Koto Majidin was located deed in the land, whereas Semerap was close to a natural lake. Geographically, these villages had the same climate and constituted paddyproducingareas where at the time of the study, these locations were inharvesting season. Five mature 7 to 9-month old ducks (1 male and 4 females) were selected from each location and killed late afternoon after being scavenged for 9.0 (KM) to 11.5 hours (Semerap) for gizzard sampling. The results showedthat based on proximate analysis of gizzard contents and corrections made on scavenging time, TME intake by ducks in KM was not different from that in SP (618 vs. 996 kcal/kg), but CP intake was less in KM (3.90 vs. 7.28; P ≤ 0.01). Relative weights of gizzards of ducks were comparable in the twolocations. Thus, difference in body weight (1,352 [KM] vs. 1,579 kg [SP]; P ≤ 0.01) was likely in part influenced by different absolute weight of gizzard (55.6 vs. 78.0 g; P ≤ 0.01) and its contents (10.60 vs. 18.03 g; P ≤ 0.01). Scavenged feeds, which were similar in both locations, composed of grits, paddy,snails, and other unidentified ingredients. This study suggested that ducks scavenged feed in KM and SP had not got sufficient energy and protein for optimum production. Under the presencecircumstances, at least additional 20 g of feed composing of energy and protein source is required to meetnutrient requirements of a duck.

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan pemahaman konsep dan hasil belajar kognitif siswa pada materi hidrokarbon melalui penggunaan pengembangan bahan ajar modul. Pengembangan modul menggunakan model Hannafin and Peck yang terdiri atas tiga fase, yaitu fase analisis keperluan, desain, serta pengembangan dan implementasi. Penelitian ini menggunakan metode kuantitatif. Sampel diambil secara acak dan terbagi dalam kelas kontrol dan eksperimen. Penelitian dilaksanakan di kelas X SMA Negeri 11 Banda Aceh tahun pelajaran 2012/2013. Pengumpulan data untuk mengetahui peningkatan pemahaman konsep dan hasil belajar kognitif siswa dilakukan melalui tes awal dan tes akhir pada kedua kelas, dan untuk mengetahui tanggapan guru dan siswa terhadap penggunaan modul sebagai bahan ajar pada materi hidrokarbon digunakan angket. Pengolahan data dilakukan melalui beberapa tahapan, diantaranya uji tingkat kesukaran, daya beda, validitas, dan reliabilitas untuk instrumen yang akan digunakan dalam penelitian. Selanjutnya, untuk mengetahui peningkatan pemahaman konsep dan hasil belajar kognitif siswa dilakukan perhitungan N-gain dari hasil tes awal dan tes akhir siswa. Uji hipotesis menggunakan beberapa pengujian, diantaranya uji normalitas, homogenitas, dan uji kesamaan dua rerata. Berdasarkan hasil penelitian dapat disimpulkan bahwa penggunaan modul hidrokarbon dapat meningkatkan pemahaman konsep dan hasil belajar kognitif siswa. Di samping itu, guru dan siswa sangat setuju terhadap penggunaan modul tersebut.

Abstract

The results of previous studies show that students of Physics Education (S1 and S2), FKIP Syiah Kuala University more than 50% do not understand the programs and roadmap of Pilar ASEAN Socio-Cultural Community as a part of the ASEAN Economic Community (AEC). The inference of those results to the implementation of learning physics and science education system needs to be implemented through a link and match learning model that can improve the ability to think critically and creatively, and students need to be trained to be problem solvers, not the problem makers.Based on these problems, through this research has been applied physics learning by using Problem Solving strategies on 25 students of Master of Physical Education and Science. At the end of the implementation study measured the ability of students to apply problem-solving strategies in accordance with Answer Sections of Problem Solving adopted from previous research. The results showed that the majority of students (78%) are able to implement the stage I (Focus on Problem) with a complete, almost all respondents (91%) was only able to implement the stage II (Describe the Physics) of about 40%, almost all respondents (91% ) can apply for the stage III (Plan The Solution) approximately 80% of all respondents have been able to implement the stage IV (Excute the Plan) perfectly, and all respondents have been able to apply the stage V (Evaluate the Answer) completely. It is expected that all staff of teaching Science materials (Physics), they are recommended strongly to implement Problem Solving as an alternative strategy for preparing students to face global competition in the ASEAN Economic Community (AEC).

Abstract

The identification of misconception in the Physics or Science learning all this time mostly used the two-tier or three-tier diagnostic test. There were several reasons why both test forms used, such as to make sure whether the students guessed the answers or understood the concepts. Besides, through the use of both tests the students confidence in choosing the answers could be identified. However, there was no explanation or study on the most effective test to identify those misconceptions. The purpose of this study was to know the effect of the one-tier, two-tier and three-tier diagnostics test toward the students answer pattern, confidence level, and understanding on the concept of anatomic nuclear. The respondents which were used in this survey research were 88 the students attending Atomic Nuclear course in Physics Education Department, Faculty of Teacher Training and Education, Syiah Kuala University. Some tests were consecutively given to the 88 respondents, the test participants could continue to the next test if they finished all questions in the previous test. The data collection used the instrument of basic Physics preconception test (Tes Pemahaman Konsep Fisika Inti/TPKFI) in the form of one-tier, two-tier and three-tier multiple choice with eight multiple choice items. The test was developed by researchers with difficulty index = 0.35, discrimination index = 0.31, validity= 0.35, and reliability= 0.90. The data analysis result showed that even though the students answer patterns were the same for all types of diagnostic tests, there was a convincing change in the students concept understanding and confidence between the two-tier and three-tier. From this research, it could be inferred that the identification of the students misconception in the Science learning would be better (had high confidence), if the diagnostic test used was higher, that was three-tier, four-tier, and thus on.

Abstract

This study aims to determine the increasing of high school students’ motivation in learning physics through the use of computer simulation media in terms of parents’ employment background. The method used in this study is quasi-experimental method. This research was conducted in class X SMAN 1 Lhoknga Aceh Besar. The data collection was gathered by giving a pretest and posttest questionnaire of student motivation. Then, the administration of a questionnaire survey was conducted to find out the background of the parents’ employment. The results of the study showed that the use of computer simulations media could increase student motivation. The survey results showed that in the experimental class the student whose father works as a vegetable seller and his mother as a housewife got the highest increase of motivation. Furthermore, students who experienced the lowest increase of motivation both parents were victims of tsunami disaster in 2004. In the control class, students who experienced the highest increase of motivation came from a family whose father works as a fisherman and his mother is a housewife. Whereas, Students who obtained the lowest increase of motivation, his father has temporary jobs and his mother is a housewife.
