APPLYING THE DEMONSTRATION METHOD TO IMPROVE SKILLS OF DISTILLATION EQUIPMENT ASSEMBLY

Ateacher must be able to involveherstudents to find the materialsthat theyare studyingit mayencourage thestudents to apply the materialsintheir daily lives. The problemfaced by the studentsofsmk-smti pontianak concerned the misconceptions in the assembly of distillation equipment. They also got confusedwhen installing condenser hoses for the line and the direction of cooling water. It was identified that when doing their practicum, the students only read the work instruction on the jobsheet withoutanydemonstration. To overcome theproblem, the teacher needs toapplythe demonstration method. This research aimedtoinvestigate whether the demonstration method could improvethe students skill indistillation equipment assembly. It wasa classroom action research(car)that consistedof 2 cycles. The research subjects were 16studentsgrouped inxif. The technique and the instrument of the data collection were an observationtechniqueand test respectively. The data were analysed qualitatively. It is found out thatthe demonstration methodimproved the students skills inassemblingthedistillation equipment. The skill improved 18.75% from75% in cycle ito 93.75% incycle ii; or the averagescore increased 9, that is, of from 76 inthe firstcycle to 85 inthe secondcyclein conclusion, the application of demonstration method improvedthe studentsskillsof distillation equipmentassembly.
