Abstract

ABSTRACTThis research focusesd on the low achievement of mathematical learning in problem solving, mathematical communication and students activity in mathematical learning was low, response to mathematical learning activity was low and mathematical learning which was applied less efficient. Therefore, it needs an effort to improve learning process, problem solving and mathematical communication. One of effort was the implementation of jigsaw cooperative learning. This research is class action research which applied on SMP Negeri 5 Padang Sidimpuan. The subject of this research was grade VII that consist of 40 students. This research was developed by teacher’s book, students’ book, LAS and instrument which consist of problem solving test and mathematical communication test. The study comprised two cycles and the test given at the end of each cycle. It concluded that the implemantation of jigsaw cooperative learning are able to improve the students’ ability in mathematical communication, active students activity, teachers’ ability in managing learning process and students’ positive response on learning devices.Keywords : Jigsaw Cooperative Learning, Problem Solving, Mathematical Communication.

AbstractAl-Quran and Hadis relied upon by Muslims to determine something of foods including halal or haram. The term halal and haram are both derived from Arabic, meaning lawful or permitted justified, while haram means not permitted or prohibited. Pigs are clear keharamannya for Muslims either fat or part resulting from an animal. Prohibition of pork has been scientifically proven / science, so that we as Muslims must eat halal food anymore either (thayyib). Key words: science, haram, halal, lard

Abstract

AbstractThe research of preparing biodegradable composite materials from polypropylene (PP) filled by fibre recovery (FR) from solid waste pulp and paper mill with meleic anhydride (MAH) as coupling agent and benzoil peroxide (BPO) as initiator has been examined. In this study, fillers composition were variaed (PP:FR)%. Composites were obtained by reflux at 170°C for 3 hour and formed to film. The charaterization were done by tensile test, DTA, FT-IR, SEM, and biodegradable test. The result showed that the optimum ratio of composite PP-FR was (90:10)% with tensile strength 17.7 MPa. The tensile strength increased by adding 3% MAH, obtained optimum tensile strength 20.9 MPa at ratio (60:40)% and by adding BPO, the tensile strength more increased to 24.0 MPa at optimum ratio (70:30)%. The reason for this improvement was detected by FT-IR studies of esterification reactions between PP-MAH with filler FR. SEM studies of the surface showed better dispersion of fibres in the matrix, a more effective wetting of fibres by the matrix, and a better adhesion between the two phases. DTA result showed decreasing of decomposition temperature of composite materials.Key words : Polypropylene, fibre recovery, meleic anhydride

Abstract

AbstractEducation aims at person’s potency development process. Here, potency turns to competence. The competence is a mirror of person’s ability and skill for work. Teacher needs to know students’ talents, and smartness. The smartness is a reachable thing. Additionally, it is not only a thing person was born with, but it might be gained through supported situation like closed-relation communication.There should be free time and opportunity for students to develop their own sense, creation and practice. Accordingly, mathematic students should stand alone to study through their potency. Being a primary subject, mathematic is not simple subject to study. Therefore, mathematic teacher should be creative and innovative. In conclusion, the teachers should have good technique and method to improve students’ multiple intelligences based on local and social characters for nation character.

Abstract

AbstrakAl-Quran as the words of God revealed to the Prophet Muhammad become a way of life to man is not only to teach about faith, worship, laws and morality, but the Quran also describes about things related to science. In the Quran there is the term al-nazhr, al-fikr,al-aql, and al-qalb which suggests some form of scientific methodology. Scientific methodology revealed this Quran has been practiced by the scientists and philosophers, the method of observation(al-nazhr), method of rational thinking(al-fikrand al-aql), as well as intuitive method(al-qalb). But according to the Quran, the use of these methods is to get the truth in order to strengthening the faith(dzikrullah).Kata kunci :al-Nazhr, al-Fikr, al-Aql, dan al-Qalb.

ABSTRACTThe position of information technology is important in all aspects of life. One of the developments that are rapidly from information technology becomes a trending topicPenggunaan Fasilitas Wifi...........Jelita 120is free Wi-Fi. In the world of lectures, students are the biggest consumer that uses Wi-Fi to work on tasks of lectures given by professors. However, the fact that the part of the students, take advantage of free Wi-Fi just to download a task without filtering or examining its contents as well as access to social networks like facebook. Conditions like this is what makes the student being lazy to think more creatively in the task portion. If a student was able to hone his thinking in doing tasks and associated costs by utilizing the free Wi-Fi, then then learning achievements obtained are very satisfactory and boasts. This research aims to know the use of the free Wi-Fi and the influence of the use of facilitiesIf students able to hone his mind in doing theirjobs perkuliahan by utilizing wi-fi, facilities and achievement iearn obtained be very gratifying and plume-. This study aims to know the use of facilities and influence from the use of facilities wi-fi. The facilities to take on duties wi-fi perkuliahan given by a lecturer. But the fact that, obtained part college students use facilities only to wi-fi m gonna download theirjobs without sift or review the content and access as social network facebook.This research uses a quantitative approach with a descriptive method. The population in this research is the entire semester 5 and 7 Mathematics Education Tarbiyah mayor STAIN Zawiyah Cot Kala Langsa 2012-2013 academic year, consisting of 412 people. The research sample is taken as a non-probability as many as 41 people with technical purposive sampling. Data collection techniques in this research is question form and documentation. Data analysis techniques were used to test the hypothesis is variance (Anava) Analysts and test t.Based on the analysis of test of normality on a variable (X) and (Y) variables have normal distributed data with simple linear regression coefficient results indicate Y = 0,452 X 27,075. from the results of the analysis using SPSS anava 20.0 retrieved Fhitung gt; Ftabel (12,517 gt; 4,09), it shows the influence of the use of u201CAda% Wi-Fi against an index of achievement students majoring in mathematics education Prodi Tarbiyah STAIN Zawiyah Cot Kala Langsa% u201D. And test results using SPSS t 20.0, retrieved thitung gt; ttabel (3,538 gt; 1,685). Thus it can be concluded that the use of Wi-Fi facilities significantly influential over student achievement index prodi mathematics education with contributions amounting to 24.3%. Therefore, it is recommended that students use Wi-Fi for things that are useful in particular in completing tasks and associated costs.
