Abstract

The equation of chemical reactions can be synchronized in several ways, including the mathematical equation of chemical reactions. In an equivalent chemical reaction, the relationship of any amount of product and reactant usually forms a ratio of a round number. An understanding of the chemical reaction equation is needed to understand the stoichiometric material, since stoichiometry is the basic material that must be well understood as the foundation for the understanding of subsequent chemicals. Stoichiometry can be used to calculate the amount of product that can be produced from a given number of reactants..

Abstract

The aims of this research are to know and to evaluate the process of Chemistry learning activities in high school. The research conducted on teachers (educators), students at SMA Negeri 1 Lueng Putu by giving questionnaires, observations and interviews. Learning is the most basic activity in the school so that the success or failure of the achievement of educational goals depends on how the learning process. It is expected to be a serious and maximum performance and supported by completing the inadequate infrastructure facilities. Based on the result of the students’ questionnaire, it found that the learning process of Chemistry activity was still not maximal. The population was all the students of class XI SMA Negeri 1 Lueng Putu which amounted to 3 classes. The sample used in this study was only 2 classes, where each class consisted of 40 students. Based on the result of questionnaire tabulation, it found that the learning process that was applied by teacher (educator) was 81,16% (good), and how the students’ learning was 66,78% (enough). Based on the results of observations on the schools, it found that the laboratories and libraries are not functioning. The results of interviews on teachers stated the use of less than the maximum media and student learning equipment is less complete. By looking at the learning process in schools, especially Chemistry less than the maximum, so it is needed to be improved to achieve the good results.

Abstract

A good teaching process is highly coveted by the community so that the achievement of results is maximum. Learning about biochemistry in high school must be done with teaching materials found in everyday life. Biochemical teaching material consists of carbohydrates which are divided into three groups, namely monosaccharide, disaccharide and polysarida. The second material is fat which is divided into two types when viewed from the source, namely animal fat (animal) and plant fat (vegetable). When viewed from chemical bonds also divided into two, namely saturated fat and unsaturated fat. The next material is a protein that functions to replace damaged cells, development in brain cells and as a biocatalyst.

Abstract

This research has aim to see the differences of learning achievement result by using lecture method and experimental method which applicated in redoks and electrochemistry discussions on students of SMA Negeri in Banda Aceh. In this research, the research used experimental method. As population is all of the students SMA Negeri Banda Aceh in class II Semester I 2008/2009 school year. Furthermore, as the sample of this research are SMA Negeri 1, SMA Negeri 2, and SMA Negeri 3. In addition, each of school taken two classes, that are the first class taught by using experimental method (experiment class), and the second class taught by using lecturer method (control class) and each class have 40 students. Thus, the total numbers of sampel in this research are 120 students in experiment class, and 120 students in control class. The instrument that used to know the students learning result is learning result test in redoks and electrochemistry discussions and it is multiple choice. Therefore, t-test of students learning result is used to examine the hypotheses both in experiment class and control class. The result of pretest that given are : the average of experiment class is 29,4 and for control class is 49,5. Moreover, the result of t-test both class are got t-count = 0,004 < t-table = 1,986 (α=0,005), in summary, there are no significant differences of result between experiment and control class. Furthemore, the result of posttest that given are : the average of the student experiment class is74,1, and for control class is 68,0. The t-test result of post-test for both classes are got t-count = 2,40 > t-table= 1,986 (α=0,05). Thus, there are significant differences of result between experiment and control class. It can be concluded that the student learning result of experiment class is higher than control class.

Abstract

Covid-19 (corona virus) can infect anyone, but the effect will be more dangerous or even fatal if it attacks the elderly, pregnant women, smokers, sufferers of certain diseases such as asthma, pneumonia, tuberculosis and diabetes mellitus and cancer sufferers. Because this disease is easy to transmit, there is also a high risk of infecting medical personnel who treat Covid-19 patients. In addition, the groups at risk of being exposed to Covid-19 are children, this is because the majority of Covid-19 sufferers are children aged 6-11 years. The purpose of the study was to determine the use of animated film promotion media in increasing knowledge about Covid-19 in class II and III students of SDN 50 Banda Aceh City in 2021. This research method is Correlative Descriptive with Random Sampling technique with a total sample of 71 students. . The time of this research was carried out on October 22-23, 2021. The results showed that of the 71 respondents before giving animated films, most of them had little knowledge about Covid-19 as many as 43 respondents (60.6%), while after giving animated films, most of them Most have good knowledge about Covid-19 as many as 53 respondents (74.6%). The conclusion is that before giving animated films, most of the students have less knowledge, while after giving animated films, most of them have good knowledge. It is hoped that respondents will increase their knowledge about Covid-19and continue to apply health protocols properly.

Abstract

Hypertension or high blood pressure is one of the main health problems in every country because it can cause heart disease and deadly brain stroke. Hypertension is seen as a serious health problem because we often don't realize it comes with few if any real symptoms. This disease can continue to get worse without realizing it to a level that threatens the life of the sufferer. Hypertension or high blood pressure is an increase in systolic blood pressure of more than 140 mmHg and diastolic blood pressure of more than 90 mmHg on two measurements with an interval of five minutes in a state of sufficient rest/calm. This study used a pre-experimental design method with the type of one group pretest-posttest design. The target in this study were the elderly in Jurong Binje Village, Jangka Buya District, Pidie Jaya Regency. The questionnaire in this study was used to examine the effect of counseling about hypertension on increasing the knowledge of the elderly in Jurong Binje Village, Jangka Buya District, Pidie Jaya Regency. The number of samples taken was 15 elderly people. It is known that most of the respondents were female as many as 10 respondents with a percentage of 66.7%, while most of them were aged 55-60 years as many as 9 respondents with a percentage of 60%. The highest level of knowledge of the elderly before being given counseling was in the moderate category, 5 people (33.3%). The highest level of knowledge of the elderly after being given counseling was in the high category, 15 people (100%). The average knowledge level of the elderly before being given counseling was 1.67 and after being given counseling was 1.00. From these results it can be concluded that there were positive results from the counseling process carried out.
