Abstract

This research is a study of the effect of visual complaints on learning achievement. High and low visual complaints are strongly influenced by student mobility or motor activity. Mobility can also maintain concentration to be maintained at a certain time. Class mobility is carried out through simple interactive learning, which is an effort to invite students to always move and always be active in the learning process. The long-term goal of research is to obtain effective learning strategies in vocational universities, while the short-term goal of research is to obtain learning methods in English subjects that are best able to provide optimal results on student academic achievement. Departing from the problem that the concentration of students decreases in line with the length of the lecture and the lack of student interaction in the classroom, a strategy is made that allows the concentration of students to be maintained during the lecture process by increasing student mobility in the classroom. To find out the impact of the treatment/ intervention on the subject's condition, a real experiment will be conducted using the two period cross over design. The assessment of the quality of the learning process was carried out with 2 cycles of study, in which each cycle was ended by giving a test/questionnaire. Data were analyzed descriptively qualitatively. Student learning achievements in the form of final grades are calculated according to the grade with the following weighting: 10% daily quiz/test + 10% assignment + 10% report + 30% Middle Semester Exam + 40% Final Semester Examination. The results showed that high visual complaints can reduce concentration and reduce student achievement.

Abstract

Weeding rice in paddy fields is mostly done by female farmers, as it is done by farmers in Kebon Bantiran village, Bajera, Tabanan. The body position of the female farmers when weeding the rice in the paddy field is bent and both feet are buried in the mud. The purpose of this study was to find out and describe the workload of female farmers when weeding rice plants in the rice fields. The sample for this study is 10 female farmers. The method of this research is the measurement of pulse with the 10 pulse-method. Data collection is done twice, after-work and after a short break. The data obtained are analysed by a t-paired test. The calculation results obtained the mean after-work pulse rate of 115.25 pulse per minute, while the resting pulse rate was 95.50 pulse per minute, decreased pulse rate was 19.75 pulse per minute or decreased by 20.68 percent. In the statistical test, the t-paired test decreased significantly (p is less than 0.05). The workload of female farmers to weed rice is a mild category. The percentage of cardiovascular load (CVL) for female farmers when weeding rice was 19.99 percent which indicates the category required for work improvement. The percentage of CVL value is calculated from the level of workload classification based on the increase of work pulse compared to the Vanwonteghem maximum pulse and categorized it into the classification of light or moderate workloads, so this need improvement by taking a short break.

Abstract

Carburetors are one of the important components on motorcycles, through modification of replacing Standard Carburetor with Racing Carburetor is one of the ways to improve engine performance. There are several types and sizes of PE, namely PE 24, PE 28, PE 38. PE 28 carburetor is often used on racing motorbikes, both Drag bikes and Roodrace bikes, where this carburetor is able to produce maximum engine performance. By testing the maximum power using a standard carburetor found at 7000 rpm engine speed, which is 11.3 HP, while the maximum power testing using a PE 28 carburetor is found at 7000 rpm engine speed, which is 11.7 HP. For testing the maximum torque using a standard carburetor found at 6000 rpm engine speed, which is 11.7 N.m, while the maximum torque testing using a PE 28 carburetor is found at 7000 rpm engine speed, which is 11.8 N.m. The use of PE 28 carburetor on a 4 stroke motorcycle greatly affects the amount of fuel consumption, it is because the PE 28 carburetor is a racing carburetor that is very suitable for those who want top speed. In addition, the advantage of the PE 28 carburetor is that it is able to improve engine performance because the type of carburetor is different from the standard and there are changes in the dimensions of the venturi hole and intake manifold, so that it can fog up more air and fuel to be brought into the combustion chamber or into the engine cylinder.

Abstract

Acceleration is the change in speed in a certain unit of time. The method applied in this research is the experimental method. The purpose of the analysis of the modification of the automatic clutch system to the manual clutch system on motorcycle acceleration is to determine the results of the modification of the automatic clutch system to the manual clutch system on acceleration. The results of the first test showed that the average acceleration in the automatic clutch system was 101.05 m/s2, and the second an average acceleration was 101.14 m/s2, so the average acceleration was 101.095 m/s2. When using the manual clutch system, the first test results obtained an average acceleration of 77.87 m/s2, the second obtained an average acceleration of 78.51, so the average acceleration was 78.19 m/s2. So the average acceleration using the automatic clutch system is 101,095 m/s2, while those using the manual clutch system are 78.19 m/s2. There was a very significant difference of 101.095 m/s2 - 78.19 m/s2 = 22,905 or 22.65%. This means the use of the manual clutch system accelerates faster than the automatic clutch system.
