Abstract

Dengue haemorrhagic fever every year become a major health problem because many areas have free-larvae-index below the standard 95%. Counseling by teaching and in persuasive context need to be implemented to elementary school children, include for DHF problems. The purpose of this study was to reveal the knowledge level difference among the children between counseling with talking method and counseling with snake and ladder game with real object as a media. This quasi experiment was conducted following non equivalent control group design, with 37 fifth grade students of Jatisawit Elementary School, in Balecatur, Gamping as the respondents, on May 2018. They were allocated into two groups, i.e. 19 students in the experimental group and 18 in the control group. Descriptively, characteristics of respondents regarding to age and gender are no different between the two groups. The data analysis shows that the intervention media game with real object significantly increased the knowledge level (p value of 0,02), meanwhile in the control group the increased was not significant (p value of 0,747). With independent t-test, the knowledge level increase difference between the two methods is also confirmed (p value of 0,02).

Abstract

The machine has noise with a high-power sound, one of the negative impacts it causes is Noise Induced Hearing Loss (NIHL), for this reason it needs a material that can reduce noise. The result of the measurement of the noise level at this sawmill industry is 96.95 dBA which exceeds the TLV, according to Permenkes No. 70 of 2016 concerning Standards and Health Requirements for the Industrial Work Environment, which is 85 dBA. The purpose of this study was to determine the effect of using a mixture of rice husk ash, sawdust and coconut fiber in a diesel engine to reduce the noise level in the sawmill industry. This type of research is a True Experiment with a pretest – posttest design with a control group, with the object of the research being a diesel engine that will be repeated 16 times at one point for each group, namely the control and experimental groups. The average reduction in bulkhead noise level is 13.08 dBA or 14.03%, with the noise level after treatment is 80.14 dBA. The Wilcoxon test to test the pre data with the control group post and the pre data with the post experimental group, the value of p = 0.000 which means less than 0.05, it can be concluded there is a difference between the noise level. Pretest and posttest in the control and experimental groups, and the independent t test obtained p value = 0.000 it means that there is a significant difference between the control group and the experimental group. However, the percentage of reduction was higher in the experimental group, so it is still advisable to use a mixture of rice husk ash, sawdust and coconut husk.
