Abstract

Based on observations from motorcycle drivers with automatic transmissions, there are several commonly criticized complaints about the lack of responsiveness. There are many ways to improve motorcycle performance. One of them is to change the contact angle inclination of the primary he pulley of the continuously variable transmission (CVT) and change the mass of the pulley accordingly. The method used in this study is an experimental research method. This method works by directly testing the effect of one variable on another. The purpose of this study is to investigate the effect of varying primary pulley tilt on power, torque, slip ratio and fuel consumption of a 110cc bike when the primary pulley contact angle and roller mass tilt are varied. That's it. The primary pulleys have contact angles of 13.5° and 14°, and pulley masses of 13 and 15 grams. The subject of this study is a Honda Beat PGM-FI 110cc bike with an engine speed of 2000-4000 rpm. 500rpm According to the results of the studies conducted, a 13.5° primary roll and a 13 gram roll achieved the best results in all tests. Maximum torque is 24.95Nm at 2000rpm and maximum power is 8.0hp at 2500rpm.

Abstract

Parents' knowledge of children's littering behavior is an important thing that needs to be considered by every parent. That needs to be considered by every parent, because it can help children's behavior towards a positive direction, especially in disposing of garbage. The purpose of this study was to determine the relationship between the level of knowledge parents with children's behavior of throwing garbage. This research design uses correlation analytics with crosssectional approach. The sample of this study was 63 respondents using random sampling technique. The independent variable in this study is parental knowledge, while the dependent variable in this study is children's littering behavior. This study is the behavior of children to dispose of garbage. Data were collected using a questionnaire of parental knowledge knowledge questionnaire and observation of children's waste disposal behavior. Data were analyzed using the chi-square test with a significance level of p<0.05. p<0.05. The results showed that almost half (46.0%) of parents' knowledge was good, and more than half (66.7%) of children's behavior was good. More than half (66.7%) of children's behavior to dispose of garbage in its place with their own awareness. The results of data analysis the results of data analysis obtained a value of p = 0.000 <0.05, meaning that there is a relationship between parental knowledge and children's behavior. Behavior to dispose of garbage. The results of this study are expected to be used as information about development in the community in parental knowledge with children's behavior of throwing garbage.
