Abstract

Transportation is basic human need in supporting various aspects of life, even almost all human activities require transportation. Arrangement of good traffic light are very needed at every intersection of the road. One of the very strategic intersection in Mataram city is Ampenan intersection. One of the factors that affect the accumulation of vehicle queues is less than optimal time when the green light is on at the traffic light. Therefore, it is necessary to study the optimal time of traffic lights based on amount of vehicles that passing and time of the green light is on. One of method to determine the optimal time of traffic light using Monte Carlo simulation method. Monte Carlo method is an algorithm for solving a problem to get better results using the probability distribution. Study uses the distribution of arrival and passing vehicles. Observation the time of arrival and passing vehicles is done in each direction of the traffic light. Results of this study indicate that the optimum time for the green light for the west direction are 21 seconds, for the east direction 21 seconds, for the north direction 36 seconds, and for the south direction 36 seconds.

Abstract

This study aimed to describe the level of critical thinking skills in Year 7 students of SMPN 1 Narmada related to the subject of Algebra. This study was quantitative descriptive. The instruments of this study implemented the indicators based on Perkins and Murphy’s levels of critical thinking skills, which are (1) clarification, (2) assessment, (3) strategy, and (4) inference. There were 352 students in this study population with 64 students as the samples were obtained with a simple random sampling technique. Written test and interview was applied as the data collection technique with descriptive statistics as the data analysis technique. The results showed that 4,69% of the students grouped as having a high level of critical thinking skills had already had the ability to answer all questions completing all stages of critical thinking skills. While 4,69% of the students categorized as having the middle level had answered the questions using their level of critical thinking skill except for numbers 3 and 4 leaving some incompleted stages of critical thinking skill. Significantly, 90,62% of the students categorized as low level were not able to answer the questions with the stages of critical thinking skills. This concluded that the level of critical thinking skills on the subject of Algebra in Year 7 students of SMPN 1 Narmada is low categorized.

Abstract

This study aims to determine the effect of problem-based learning models on social arithmetic material on the achievement of mathematics learning for grade VII students of SMP Negeri 2 Lingsar for the 2021/2022 school year. This Quasi-Experimental Design research is designed by The Posttest Only Control Group Design. The population is all grade VII students of SMPN 2 Lingsar, as many as 278 students. Sample determination is carried out by the Cluster Random Sampling technique. Class VII.5 used a problem-based learning model with 31 students as an experimental class, and Class VII.9 used a direct learning model with 30 students as a control class. The data on the achievement of learning mathematics is obtained through the final test. The assumption tests in this study are the normality test and the homogeneity test. Data analysis in this study used descriptive statistical analysis and a t-test. The results showed that the average learning achievement of the experiment class was 79,10 greater than the average learning achievement of the control class, which was 70,23. In this study, the problem-based learning model had a moderate influence on 79% of the expectations of mathematics learning achievement of grade VII students

Abstract

Learning is an interaction process of students with teachers and the learning sources in a learning environment. Therefore, the planning is needed to ensure the learning process run properly, consisting of 3 stages namely designing/composing, the learning implementation, and the evaluation and reflection. Those three stages can be improved by the Lesson Study for Learning Community (LSLC) activity. Based on the discussion with some principals and mathematics teachers of SMP and MTs in Labuapi, West Lombok, it was revealed that: i) mathematics is a subject which attracts less interest of junior high school students in Labuapi, ii) some mathematics teachers still found difficulties in composing an innovative learning devices which can guide students to find out the concepts, principles, and the solutions from the mathematics problems, and also they still have difficulties in designing one-page learning scenario which can actively involve students in an enjoyable learning process. To solve the problems, the mentoring activity in composing the learning through the LSLC activity is urgently needed. The activity was carried out by utilizing some methods, namely: speech, question and answer, discussion, and conducted mentoring activity when mathematics teachers discussed about the composing of LSLC based learning devices. From the mentoring activity conducted in 3 and 10 until 13 of September 2022, it was concluded that the mentoring activity was able to improve some aspects as follows: i) the understanding of mathematics teachers of SMPN/MTs in Labuapi, West Lombok in composing an innovative learning device, consisting of lesson plan or lesson design, learning materials, learning media, and assessment instrument; ii) the skill of mathematics teachers in the level of junior high schools in Labuapi, West Lombok in designing the learning devices as set in the curriculum of 2013; iii) the collegiality among teachers of SMPN and MTs in Labuapi, West Lombok in teaching and fulfilling students’ right from the sharing of experiences through the LSLC activity.

Abstract

This study aims at determining the effect of the use of an active learning strategy type of giving questions and getting answers on the mathematics learning outcomes of elementary students. This research is under Non-equivalent Control Group Design of Quasi Experimental Design where purposive sampling is used as sampling technique. The population of this study consists of 44 students with observation, tests, and documentation used as the data collection technique. The research instrument used are test of learning outcomes and observation sheets. The normality test was done by calculating the data in the form of pre-test and post-test mathematics learning outcomes using the Kolmogorov Smirnov formula with a sig level of 5% (0.05), after the data was normally distributed, the homogeneity test obtained from the post-test calculations, then hypothesis testing with t-test using the calculation of students’ post-test data. The results of data analysis shows that the value of sig 2 tailed is 0.000, which is less than 0.05, thus, based on the research hypothesis, if the value of sig 2 tailed ≤ 0.05 t-table, then Ho is rejected and Hₐ is accepted. This shows that there is an effect of using an active learning strategy with the type of giving questions and getting answers on the mathematics learning outcomes of elementary students. The results of this research are expected to be used as a reference for further research on different subjects.

Abstract

Implementation of Mathematics Learning for Children with Special Needs at special school (SLB) Negeri 1 Mataram Academic Year 2021/2022. The subjects of this research are teachers and students of VIII grade of Tunagrahita at Children with Special Needs at special school (SLB) Negeri 1 Mataram. The two chosen subjects are the class teacher and the randomly chosen student. This research is a Descriptive qualitative research. The data were collected in three phases, which are observation, interview and documentary. The result of this research shows the learning process for Children with Special Needs at special school (SLB) needs special treats and patterns for each student, even in fact the teachers still use the conventional method to teach them. The students still need guidance every hour. The teachers use more than one method as in other schools. The mathematics learning process of Children with Special Needs at special school (SLB) is little bit different to public schools where the teachers here have to be really slow when explaining the materials to the students and the teachers need to repeat more than twice in order that students understand it well. This Children with Special Needs school (SLB) uses the same evaluation as public schools use.
