Application of Constructivism Approach in the Learning of Initial Value Matter and Boundary Requirement Course

The purpose of this research is to repair the mathematic learning process of Initial Value Matter and Boundary Requirement (IVMBR) course. The variables which have been examined (1) the activities of lecturer and students in learning process, (2) the development of student grades, and (3) the completeness of student result in studying of IVBVP. These actions have been done in three cycles based on data's analysis, we get the result (1) the lecturer and students activities in learning process have been improved, (2) the development of student grades is rather the same in three of the cycles, and (3) the student who could reach the studying completely. After first cycle, these students get A or B increasing to 62,50,`4%, and after second cycle, the completeness of study has increased to 66,67%, and after third cycle, the completeness of studying have increased to 75,00%. Based on these informations, the constrctivism learning is good to use in learing of IVMBR course

Penerapan Project Based Learning (Pjbl) untuk Menigkatkan Hasil Belajar Matematika Siswa Kelas Vii4 SMP Babussalam Pekanbaru

This research is a class action research that aims to improve the learning process and to increase the student's mathematics learning outcomes by applying Project Based Learning (PjBL). The subjects of this research are the student of class VII4 SMP Babussalam Pekanbaru at second semester of academic years 2014/2015, which amounts to 19 students. This research consists of two cycles, each cycle consists of four stages: planning, implementation, observation, and reflection. Data collected through observation and learning outcomes test. Data analysis is done by observation data analysis and student's mathematics learning outcomes data analysis. The action is successful if the scores of teacher's activities and student's activities increase in every meeting and the number of students who reach Minimum Mastery Criteria increases in every cycle. Scores of teacher's activities from the first to the sixth meeting are 93.55, 94.45, 100, 100, 100, and 100. While the scores of student's activities from the first to the sixth meeting are 93.33, 95.24, 100, 100, 100, and 100. Percentage students that reach knowledge Minimum Mastery Criteria in base score is 42.11% increase to 57.89% at the first cycle and 68.42% at the second cycle. The result of this research showed that Project Based Learning improve the learning process and increase the mathematics learning outcomes the students of class VII4 SMP Babussalam Pekanbaru at second semester of academic years 2014/2015

Penerapaan Model Pembelajaran Kooperatif Pendekatan Struktural Think Pair Square Untuk Meningkatkan Hasil Belajar Matematika Siswa Kelas Ix.4 SMP Negeri 21 Pekanbaru

This research was based on the students' achievement in learning mathematics especially grade IX.4 of SMPN 21 Pekanbaru under the Mastery Minimum Criteria with percentage of 27,77%. The subject of basic competence were about triangle. The teacher-centered learning was still used to teach materials during the learning process. The research conducted was the Classroom Action Research. The aims of this research is to improve the learning process and results on the students learning mathematic by implementing cooperative learning model structural approach of Think Pair Square. There were 36 students in the class consisting 13 boys and 23 girls as the participant of this research. The instruments of data collection in this research were observation sheets and students Mathematic tests. The observation sheets were analyzed in qualitative desciptive, while the students' Mathematic tests were analyzed in quantitative desciptive. The qualitative desciptive showed an improvement of learning process prior to the action on the first and second cycles. The results of this research showed an increasing number of students learning Mathematic from the basic score with percentage 27,77% to 36,11% on the first test and 50% on second test. Based on the result of this research could be concluded that the implementation of Cooperative Learning Model structural approach of Think Pair Square can improve the students' achievement of learning Mathematic in grade IX.4 of SMPN 21 Pekanbaru in the first semester academic years 2014/2015

Penerapan Pembelajaran Kooperatif Tipe Student Team Achievement Division (Stad) Untuk Meningkatkan Hasil Belajar Matematika Siswa Kelas III SD Negeri 25 Bagan Melibur

This research was based on the mathematics learning outcomes of students at class III SDN 25 Bagan Melibur. There were only 13 of 24 students (54,17%) who achieve the Mastery Minimum Criteria on topic about using the measuring tool in problem solving and the learning process is still teacher centered. This research is action research which aims to increase the mathematics learning outcomes of students at class III SDN 25 Bagan Melibur through the implentation of cooperative learning in type student team achievement division (STAD). The subject is 24 students at class III SDN 25 Bagan Melibur which consist of 10 boys and 14 girls with the heterogenous ability level. The instruments of data collection were observation sheets and test of mathematic learning outcomes. The observation sheets were analyzed in qualitative desciptive, while the test of mathematic learning outcomes was analyzed in quantitative descriptive. The qualitative descriptive showed that there is an improvement of the previous learning process to the first and second cycle. The result showed an increasing number of students who achieve the Mastery Minimum Criteria from the basic score with the percentage 54,17% to 75% on the first daily test and 83,33% on the second daily test. Based on that result, it can be concluded that the implentation of Cooperative Learning in type student team achievement division (STAD) can improve the mathematics learning outcomes of students at class III SDN 25 Bagan Melibur on second semester academic year 2014/2015

Peningkatan Nilai Ekonomi Ekosistem Mangrove melalui Pengolahan Buah Api-Api (Avicennia SP) sebagai Bahan Makanan di Desa Sungai Kayu Ara Kabupaten Siak

Mangrove forests have many roles, which can be grouped into biological, physical-chemical, and economic roles. Grey mangrove (Avicennia sp) fruit has the potential as a raw material for cakes that are still underutilized. The purpose of community service is 1. To increase the value of mangrove ecosystems through the processing of grey mangrove as ingredients for making cakes in Sungai Kayu Ara Village, Sungai Apit District 2. To increase the types of cake making materials for communities around mangrove forests in particular, and 3. Improving the community's economy which continues to increase public awareness to preserve the mangrove ecosystem in Sungai Kayu Ara Village, Sungai Apit District. The results of this counseling activity showed that the participants seriously listened to the material delivered by the extension team from beginning to end. The participants can understand the material presented well and play an active role in the question and answer session, discussion, and directly involved with the speakers and students in making muffins and puddings. As many as 90% of participants who never knew the gey mangrove fruit could be turned into flour after counseling became all of them. Participants who previously only 15% knew of the potential of fires for baking ingredients after counseling activities became 100% understood. As many as 90% of participants believe that with the increased economic value of mangrove forests, mangroves can be sustainabl
