Abstract

The Use of Antagonistic Bacterial as Biocontrol Agents to Wilt Disease (Fusarium oxysporum f.sp.cubense) on Banana Susanna Jurusan Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Syiah Kuala Banda Aceh ABSTRACT             Fusarium wilt or panama disease caused by Fusarium oxysporum f.sp. cubense is on of the important disease on banana. Recently there is no such effective methode for controlling the disease. The use of fungicide to control the disease can make new races of the fungal pathogen is very virulent.  The use of biocontrol agent such as Pseudomonas fluorescens and Bacillus subtilis is alternative methode to control fusarium wilt.  The aim of this experiment was to find out the most effective antagonist bacterial to control fusarium wilt on banana.  The study was carried out in Mycology Laboratory of IPB and green house and Phytopathology Laboratory of Balitbio, Bogor from January to October 2001.  Six treatments in this experiment were arranged in randomized complete design with 3 replications.  The result showed that Pseudomonas fluorescens and Bacillus subtilis were reducing Panama disease fusarium wilt on banana. Both antagonistic bacterials were effective to control fusarium wilt.

Abstract

The Correlational research with this quantitative approach aims to determine the relationship between the ability to memorize the Al-Quran and the results of physics learning at the Ulumul Quran Senior High School Sigli. The sample in this study were students of Ulumul Quran State Senior High School class XI Sigli totaling 29 people. Data collection was obtained with documentation for the ability to memorize the Al-Quran and test instruments for the results of learning physics. Processing data using correlation coefficients and hypothesis testing through the product moment equation. The results of the correlation coefficient show the ability to memorize the Al-Quran with the results of physics learning students of Ulumul Quran Public High School Sigli with a calculation of 0.427 categorized as medium and the results of hypothesis testing obtained rcount rtabel that is 0.427 0.367 then the research hypothesis is rejected, meaning there is a significant relationship between the ability to memorize the Al-Quran and the results of physics learning of the students of the Ulumul Quran State High School Sigli.

Abstract

Students’ critical thinking skill of class X MIA-1 in SMAN 2 Bukit is very low. There is the effort to improve critical thinking of students applying Project Based Learning model (PjBL). The purpose of this research is to determine whether there is an enhancement in students’ critical thinking skills using the Project Based Learning model. This research is Classroom Action Research which was carried out as many as III cycles. The subjects in this research were all students of Class X MIA-1 in SMAN 2 Bukit, consisted of 16 students. The instrument used to collect the data was tests including pre-test, post-test, teacher and student activity sheets, and observation sheets of learning management using Project Based Learning model. The results showed that students’ critical thinking skill when Project Based Learning model applied was better than the learning which was not using The Project Based Learning model. It happened because using Project Based Learning model, the students played a role actively as learning center were given an issue in the project then they were asked to solve it.

Abstract

This study aims to identify and differentiate the level of understanding of the electrical concepts of students' Grade XII Senior High Schools in Central Aceh. The population of this study was all students of Science students Grade XII Senior High Schools in Central Aceh which consisted of 19 senior high schools. The sample in this study were 115 students from six senior high schools in Central Aceh. The determination of the sample is done by purposive sampling. The approach which used is a qualitative approach with the type of descriptive research. Data collection techniques in this study used the test method. The form of the test instrument used is in the form of a three-tier test with a total of 12 items. The technique of data analysis was used in this study is percentage analysis. The percentage of the results shows there were 7.72% of students understood the concept, 51.52% of students lacked understanding of the concept, and 40.72% of misconceptions students. Thus, it can be concluded that the level of understanding of the electrical concepts of students senior high school in Central Aceh is at level 5 means very poor. As further recommendation for similar research it is best to not only identify the understanding of concepts, but also to overcome the lack of understanding of concepts and misconceptions in students so that students' understanding of concepts increases, especially in electrical concepts.

Abstract

Physics is a science that discusses every result of studying the answers to the question of causes, as well as natural phenomena that can occur. The most complex problem experienced by students is the lack of skills in solving physics problems for students. The low problem solving ability of students resulted in the ability to master the basic concepts of students. This study aimed to observe the escalation of problem solving skills after the implementation of the PIL learning model in physics at MAN 6 Aceh Besar. This research is included in the type of quasi-experimental research by designing a nonequivalent control group using 2 class samples as the experimental class and the control class. The population of this study was 64 students with 43 students participating in the study. Purposive sampling method was used in order to select the study sample. The collected data was analyzed using an independent-t test technique. This study observed that PIL learning models gave a positive impact to student autonomous learning and problem solving skills. The escalation of both variables was observed from the N-Gain score. On the problem solving skills, the control group reached 0.50 N-Gain score and the eksperimen group reached 0.79.
