The aim of this study to determine: a) the consentration of carbon monoxide in the air in District Medan Sunggal, b) the relationship between traffic density and the concentration of CO (Carbon Monoxide) in Medan Sunggal, c) is there the relationship between the condition of physical and chemical environment on the concentration CO in Medan Sunggal. This study was conducted in December 2013- February 2014 in the three location, they are: 1) Jl. Arten Ringroad, 2) Jl. TB Simatupang, 3) Jl. Setia Budi, air analysis performed in BTKL PP Medan. The design of this study using the pearson product moment correlation. The parameter measured were the number of level of CO, the physical-ehemical properties and the totality of traffic density. The research findings indicated that: the highest level of CO was in Jl. Setia Budi with 17 ppm while in the Jl. TB Simatupang was 11 ppm and in the Jl. Arten Ringroad 8 ppm. There is a significant relationship between traffic density with the content of CO levels with the value r=0,9. The correlation is very high, the correlation is positive significant. By counting using the pearson product moment analysis was obtained tcont (5,4) ≥ t table(1,895). There is relationship between traffic density and the levels of CO in the air. While the dampness and wind speed on the consentration of CO is found negative correlation. The correlation of temperature on the concentration of CO is r=0,9, but there is not significant correlation by t hitung(2,1) ≤ dari t tabel (6,314).

Mind mapping (pemetaan pikiran) diadopsi untuk mencapai hasil pembelajaran yang baik. Peta pikiran ini menggambarkan ide menjelaskan, menerangkan defenisi dari suatu materi dan mencari solusi pada suatu masalah. Menempatkan informasi keluar dari otak dan mengambil informasi keluar dari otak merupakan cara yang tepat untuk mencatat materi yang kreatif dan efektif. Peta pikiran di terapkan dan digunakan untuk member pandangan secara keseluruhan pada suatu pokok permasalan dan membantudalam mengingat, mendapatkan ide, yang pasti memunculkan kreatifdan inovatif.

Students should have a good mathematical connection ability to support their learning success. Many factors affect the mathematical connection ability, including prior knowledge and emotional intelligence. This study aimed to describe the simultaneous and partial effect of students’ prior knowledge and emotional intelligence on mathematical connection ability. This study involved 34 ninth graders of one of the public junior high schools in Lembang Regency, Indonesia, as the sample. The data was collected using a test consisting of a prior knowledge test and a mathematical connection ability test on the circle topic, and a questionnaire to measure students’ emotional intelligence. We analyzed the collected data by descriptive statistics, multiple regression, and partial correlation. The results revealed that the prior knowledge and emotional intelligence together had a significant effect on mathematical connection ability, with a contribution of 23.6%. In addition, there was a significant positive effect between prior knowledge and mathematical connection ability with a contribution of 75.1% and a significant positive effect between emotional intelligence and mathematical connection ability with a contribution of 12.2%.

AbstractAnalysis of learning difficulties in mathematics in class X matrix material which is rarely done by teachers because of their busyness in fulfilling their teacher administration, is the reason for this research. The research method used is descriptive research with the aim of explaining the conditions of student learning difficulties that occur in understanding the matrix material. The instruments used were learning observations with a Likert scale, a matrix test with 20 multiple choice items and interviews with 10 questions. Before using these three instruments, expert validation was carried out, and trials for matrix test instruments were carried out to determine the level of reliability and validity of the instrument. The population of this study was 95 students and only 10 students were used as research samples, the sample selection was using the purposive sample method. The results obtained were 63.64% of students had difficulty mastering the matrix concept, due to insufficient prerequisite material.

The government limits the social activities during the Covid-19 pandemic; as a result, the learning process was no longer carried out face-to-face. Therefore, an appropriate alternative was needed to facilitate the learning process. This study aimed to design a valid Lectora Inspire-based matrix learning materials for grade XI high school students. This research was a part of development research utilizing 4D model by Thiagarajan. However, this study limited only on defining and designing stage. Defining and designing were conducted through a literature review followed by measuring the level of validation of Lectora Inspire-based learning materials. This research was conducted for three months, from July to October 2020. The instrument was the validation sheet given to 4 (four) material experts and 2 (two) media experts for Lectora Inspire-based learning materials. The results showed that the learning material developed based on Lectora Inspire had met the valid requirements. The results of observation from the validators towards the the materials and media showed a good score after the materials were revised as suggested by the validators. Lectora Inspire – based learning materials developed had many advantages compared to the learning materials created using other programming applications.
