This research aims to determine learning media products based on e-learning in basketball game material. Development of e-learning based learning media uses a websitebased electronic circuit. Through e-learning students can simplify the learning process with digital concepts that make it easy for students to access the content that is on the website and students can learn wherever and whenever. In this study the researchers used the research and development (R&D) method steps. the research will be divided into three stages, namely analysis, design, evaluation and product trials. The study population was 12th grade students consist of 12 classes. The sampling technique was used by random sampling. Researchers took samples of class X Mia VIII of SMA Negeri 3 Medan totaling 34 students and 2 physical education teachers. Validity test is conducted by 1 material expert and 1 media expert. Product feasibility tests carried out 3 times the trials, namely individual group trials, small group trials and limited trials. The results of this study are learning media in the form of websites containing material, pictures, and videos about basketball games in accordance with the curriculum for class X students, which are able to do passing, dribling, and shooting. From the data it can be concluded that this media is appropriate to be used, able to attract students interest in learning the material so that it can improve students understanding of basketball subjects.
Abstract. Biobriquettes as alternative energy that can replace the role of kerosene. Biobriquettes made from agricultural waste biomass. Biobriquettes durian peel has been researched and developed continuously to obtain optimal quality in terms of calorific value, compressive strength and duration of ignition. In making durian peel biobriquettes needed other biomass mix to sustain duration of Ignition for biobriquettes durian skin quickly burned out. Stages of making biobriquettes durian skin are: material of drying, carbonization of biomass, grinding, mixing with adhesives, and printing. Carbonization process is a process that is important in obtaining the biomass charcoal. Carbonization is done by means of karbonisator pyrolysis. The purpose of this research is to study the process of carbonization to obtain biobriquettes durian skin that of quality in terms of value compressive strength, calorific value, and duration of ignition. Variations that done was kind mix of biomass,coconut shells and palm shells with the massa ratio 2 : 1, type of adhesive used tapioca powder and banana peels, carbonization of temperature 200" 300" " skin with a mixture of coconut shell and adhesive tapioca powder and carbonization temperature of 300 " ! cm 2 . The calorific value of the highest on the mix of skin durian with coconut shells and adhesive banana skin with temperature of carbonization 400 " g, and duration of ignition highest on a mixture of skin durian with coconut shell and adhesive banana skin at a temperature of carbonization 300 "
The purpose of this study was to determine the interests and factors that influence it to continue their studies to vocational high school. This type of research uses quantitative methods. The population in this study were all grade IX students, totaling 250 students. Data collection techniques using a questionnaire. Data were analyzed using descriptive statistics. The results showed that most of the IX grade students at SMP Negeri 1 Sikur had an interest in continuing their study at SMK with a percentage of 42%. And the factors that influence it are: (a) the factor of student interest in a particular department that has a percentage value of 78%. (b) the factor of school condition or image of SMK which is considered good by students has a percentage value of 48% (c) the socioeconomic status factor of parents who have a percentage value of 89%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
