Abstract

Linear Algebra is a mathematics subject needed to be mastered well by mathematics education students. Mathematics student-teachers need to master it well as it is one of the basic of mathematics school. However, students’ achievement as the learning outcomes of understanding Linear Algebra is not maximized well due to limitations in exploring and elaborating the concepts in it. Therefore, the response/tutorial program is regarded as one of the solutions that can be used to maximize student understanding. Through the response/tutorial program, students can explore concepts and issues related more depth. Thus, this study aims to look at the effect on the response/tutorial program of students’ achievement in learning Linear Algebra of FIP UPH Mathematics Education. The findings showed that there is a significant effect on the application of response/tutorial program toward the learning outcomes of students of Mathematics Education at FIP UPH. Keywords: tutorial program, student’s achievement

Abstract

The research aims to determine the optimal dosage of sheep manure and the thickness of the bamboo leaf litter mulch on increase growth of Celery. The research method used by experimental method using group randomize block design, 5 x 3 factorial with 3 replication. The first factor was the adding of sheep manure (P), consist of five levels doses, i.e : without manure (p0); 2,5 g/kg of soil (p1); 5 g/kg of soil (p2)l; 7,5 g/kg of soil (p3) and 10 g/kg of soil (p4). The second factor was bamboo leaf litter mulch (M), consist of three levels, i.e : without mulch (m0); mulch with thickness 2,5 cm (m1); mulch with thickness 5 cm (m2). Parameter observed were the plant height, the number of leaf, the leaf area, the shoot dry weight and the root dry weight. The data obtained was analyzed using Anova and Duncan Multiple Range Test (α=5%). Commonly, sheep manure fertilizer dose 5 g/kg of soil (d2) and bamboos leaves litter mulch on the tickness of 5 cm (m2) was the optimum dose for growth of Celery. The result of this research showed interactions beetwen the adding of sheep manure and bamboo leaf litter mulch in increasing the average of the plant growth on the plant height (38 cm) and the number of leaf(34,67 leaves). Keywords : sheep manure, bamboo leaf litter mulch, celery

Abstract

Noise is one of the major environmental health problems in big cities. Noise is an unwanted noise that can interfere with and or endanger health. Road traffic is a major source of noise that disrupts most urban communities. The impacts of noise in the housing environment on public health include communication disturbances, psychological disorders, complaints and demonstration actions. The purpose of this research is to know the noise level at Flyover Pasar Rebo and HI Roundabout and to know whether the noise level in Flyover Pasar Rebo and Bundaran HI is still suitable for human hearing. Based on the research that has been done, obtained that the level of kebisisngan in Flyover Pasar Rebo is 62,25 dB. With the highest average noise level of 69 dB which occurred during the day at 11.30-12.00 WIB and at 12:00 to 12:30 pm. While the noise level at Roundabout HI is 61.50 dB. With the highest average noise level of 65 dB which occurred in the morning at 07.30-08.00 WIB. From the data it can be seen that the noise level in Flyover Pasar Rebo is higher than the noise level at Bundaran HI. This is due to the number of vehicles traveling on the highway Flyover Pasar Rebo more than at the HI Round about. Noise levels in the Pasar Rebo and HI Roundabout flyovers are already at "hard" levels and this is not good for health especially on human hearing.Keywords: Noise, Traffic, Flyover Pasar Rebo, HI Roundabout

Abstract

This research is based on the problem of low mathematical reasoning ability of high school students. This study aims to examine the improvement of mathematical reasoning ability among students who get Differentiated Instruction approach and conventional learning. The research design was quasi experiment with non-equivalent control group research design using Purposive Sampling technique. Instruments used include mathematical prior knowledge test, mathematical reasoning tests, observation sheets, and interview guides. Quantitative analysis was performed by using t-test and two-way anova test. The result of the research shows that (1) the improvement of student’s mathematical reasoning ability through DI learning is better than conventional learning, (2) The improvement of student’s mathematical reasoning ability through DI learning is better than the students who follow the conventional learning in terms of Mathematical Prior Knowledge. Keywords: Differentiated Instruction, Mathematical Prior Knowledge, Mathematical Reasoning.

Abstract

This research was intended to produce flipped classroom learning tools on impulse and momentum materials to help overcome insufficient time to get all students to understand the material well, and to know the validation of products by experts and practitioners and to seek out the attractiveness, convenience, and usefulness of the tools. The development model used in this research was the ADDIE model consisting of five phases: analysis, design, development, implementation, and evaluation, which were restricted to the development phase. In the analysis phase, it was done by doing requirement analysis by giving questionnaires to students and interviewing to a teacher in Metro 1 Public HighSchool. At the design phase, it was done by producing learning tools that include syllabus, lesson plans, lessons video, student’s worksheet for video’s companion, and student’s worksheet for classroom learning. At the development phase, it was done by testing the product. The result obtained from the expert validation test was 3.58 of the average product score with the qualification is very valid, the practitioners validation test result was 3.66 of the average score with qualification is very valid, and the result of the 1-1 test is 3.47 of the attractiveness average scores, 3.32 of the convenience average scores, and 3.70 of the usefulness average scores, with qualifications are very attractive, very convenient, and very useful. The conclusion from the results of this development research is the flipped classroom learning tools for impulse and momentum materials are worthy to betested in learning physics.Keywords: ADDIE, Development, Impulse and Momentum, Learning Tools.

Abstract

This research have been designed a structure of artificial neural network (ANN) with using backpropagation to recognize signal pattern of human voice. The signal should first be processed with Linear Predictive Coding (LPC). Linear Predictive Coding (LPC) used for extraction characteristic. Producing matrix with 24 x50 orde which is then becoming input data for Artificial Neural Network Backpropagation (ANN-BP). There nets consist of 4 layers. Those 4 layers are : 1 input layers with 24 neuron, 2 hidden layers which are devided as 15 neuron at the first hidden layer and 10 neuron at the second, The last output with 5 neuron.For 5 training data, parameter characteristic value of net such us: Learning rate value (alpha) = 0,05 and mu value (μ) = 10-3with using by sigmoid bipolar activation function. The result of the research shows that the nets can recognize as 100 % of 25 trainning data, 74 % of 25 testing data.Keywords : Artificial Neural Network, Back propagation, voice recognation

Abstract

The background of this paper is the defecient of the society’s recognition of geometry in mathematics. The purpose of this paper is to introduce closer the society to the uniqueness of geometry in mathematics, so that the community’s knowledge about the variety of geometry in mathematic will increase and grow broader. This is hope to benefit the society by increasing their intrest to learn deeper about mathematics. To solve this problem, the solution offered as follows: introducing one of the unique geometry of platonic solid, through everyday life objects. In this case, as the student of Mathematics Education Study Program Teaching and Science Faculty of Universitas Kristen Indonesia (UKI), is making platonic solid lantern to introduce platonic solid to the society. Platonic solid is the combination of five geometry shapes composed by tetrahedron, hexahedron, dodecahedron, octahedron, and icosahedron.Keywords: Platonic solid (tetrahedron, hexahedron, dodecahedron, octahedron, dan icosahedron).
