Abstract

The purpose of this research was to investigate the effect of layers number towardflame resistance ofripoxy R-802 EX 800 gr/m2 woven roving e glass fiber glass composite. The flame resistance characteristic studied were the ignition time and the burn rate of ripoxy R-802 EX800gr/m2 woven roving e glass fiber glass composite with the number of fiber glass layers variation (up to 5 layers).The method which used  in this research was experimental method. The research was done at Engineering Materials Laboratory, Mechanical Engineering Department, Engineering Faculty, of Sebelas Maret UniversitySurakarta which located at Jalan Ir. Sutami No.36 A Surakarta. The equipment which used to study composite burning resistant was burn tester based on ASTM D-635. The specimens in this research was ripoxy R-802 EX800gr/m2 woven roving e glass fiber glass composite. Burning test was done based on ASTM D-635 standard (horizontal burning test). The data analysis which used in this research was descriptive analysis method.Based on experimental result can be concluded: (1) The effect of fiber glass layers number indicated more fiber glass layers number caused increasing of ingnition time and decreasing burn rate at composite. It was indicated that more fiber glass layers number will decreased composite burn rate. (2) 5 woven roving 800gr/m2 fiber glass layers caused this composite inflammable and the best variation of spessimen, because the fire extinguished before recommended distance based on ASTM D-635UL 94.

Abstract

This research is a Classroom Action Research which conducted in two cycles. Each cycle consists of planning, action, observation, and reflection stage. The research was conducted class XI Mechanical Engineering academic year 2014/2015. Data obtained through field observations, interviews, achievement test (pre-test cycle, the first cycle and second cycle) and documentation. This study uses comparative descriptive data analysis techniques. It shows that the implementation of cooperative learning model Think Pair Share (TPS) improves the student critical thinking skills and learning outcomes at class XI Mechanical Engineering academic year of 2014/2015 in the subjects of Lathe Machining. In the pre-cycle stage where conventional method was used, it is found that the critical thinking skills and learning outcomes is quite low. When the cooperative learning model Think Pair Share (TPS) was applied, the student critical thinking skills and student learning outcomes increase eventhough it was still under the research target of 70% on each of the indicators of critical thinking skills and a minimum of 70% of students completed the minimum mastery criteria (?75). The target value of critical thinking skills and learning outcomes in the second cycle until been reached the intended target. An increase in the percentage of students who passed the minimum mastery criteria of pre-cycle of 34.375% to 78.125% in the second cycle or an increase of 43.75%.

Abstract

The purpose of this research was to determine the influence of  feedrate variation, timing of cooling  variation, and the interaction between feedrate and timing of cooling to rate wear HSS end mill cutter in machining result CNC milling with ST 40 steel. This research is an experimental research using two factor independent variable (feedrate and timing of cooling) and one dependent variable (rate wear of HSS end mill cutter). The results data of this research described using descriptive analytic method. The results of discussion with this method was enhancement of feedrate and timing of cooling the rate wear cutter increases. Type of cutter wear that occurs is flank wear and began to grow relatively quickly then followed by a relatively slow growth to a certain cutting. The smallest edge of the cutter rate wear occurs when interaction feedrate 0.11  mm/rev with a timing of cooling 10 minutes value is 562.57 ?m, while the largest edge of the cutter rate wear occurs when interaction feedrate 0.15 mm/rev with a timing of cooling 20 minutes value is 958.65 ?m. This research suggests that interaction between feedrate and timing of cooling has a certain influence to rate wear of HSS end mill cutter in machining result CNC milling with ST 40 steel.
