Abstract

This research aims to enhance grade XI students? motivation and achievement at SMK Bhinneka Karya Surakarta by applying cooperative learning type think pair share (TPS) for automotive chassis learning process.This is an class action research (CAR). In the basis of data analysis, the application of cooperative learning type think pair share (TPS) was able to boost students? motivation and achievement. The increase of students? motivation in learning automotive chassis subject could be seen from motivation observation sheet. The preaction percentage of students? achievement at class XI TOA was 49.10% with less active category, the first cycle of 65.95% with moderately active category and the second cycle was 80.29% with good activity category. Meanwhile, in class XI TOB the percentage was 47.22% with less active category, the first cycle of 63.54% with moderately active category and the second cycle was 81.60 % by category of activity either. The accomplishment value of the students preaction as shown by prettest score was 0% of the total 63 students of of class XI of automotive engineering, then there was increase on cycle I results-posttest completion percentage of 47.62% with low criteria. Later in the second cycle averages the percentage who completed the posttest score of 82.54% with a high criteria.It then could be inferred that the application of cooperative learning type think pair share was proved effective in enhancing students? motivation as shown by the increase on each cycle in which the target achievement was set to 75%. The students? accomplishment also reached the minimum target that was 75% for automotive chassis learning process at SMK Bhinneka Karya Surakarta

Abstract

The purpose of this research was to determine the bending characteristics of composite sandwich cantula fiber using a cardboard core thickness variation of type BC - flute. This research uses descriptive quantitative method. The research began with the manufacture of sandwich composite material then the material given bending test using a Universal Testing Machine (UTM). Bending testing refers to ASTM C-393 which would result in another calculation, the bending stress and shear stress core face. Face is composed of a fiber composite cantula as filler, Unsaturated Polyester resin as a binder BQTN-EX Yucalac 157, and Metyl Etyl Ketone Peroxide (MEKPO) as a catalyst. Core uses cardboard type BC - Flute compiled by PV Ac - Fox with a thickness variation of 10 mm, 20 mm, 30 mm, and 40 mm. Epoxy adhesive using Versamid 140. The results showed that the thickness variation affects the bending stress composites, core shear stress and bending stress face. The addition ofthe composite thickness resulting impairment the composite bending stress, core shear stress and facing bendingstress. The highest average value occurs at a thickness of 10 mm with a core voltage of 17,47 MPa composite bending, shear cores of 0,75 MPa, and face bending stress of 18,84 MPa.

Abstract

The purposes of this research are: (1) to find out the effect of Alkali on the bending strength of human hair fibre composite. (2) to find out the time needed on the alkali treatment to reach an optimum bending strength on the human hair fibre composite. This research was conducted  in Material Laboratory of Engineering Faculty of Sebelas Maret University of Surakarta. The researcher used human hair fibre and polyester resin 157 BQTN which are added with MEXPO 1% catalyst as the main materials. Human hair fibre composite with variation of alkali treatment those are 0, 30, 60, 90 and 120 minutes was used as the research sample. The composite was made through press molding way with volume fraction ratio between matrix and filler in the amount of 60% : 40%. The composite was made based on ASTM D 790 standard. The results of this research show that alkali treatment give an effect on the bending strength of human hair fibre composite. Hair with longer alkali treatment shows higher bending strength. This is proven by the result of the research that shows the bending strengths without alkali treatment, within 30 minute of alkali treatment and within 60 minute of alkali treatment for each are 34,821 MPa; 38,012 MPa dan 43,679 MPa. Overlong alkali treatment (more than 60 minutes) will break the hair fibre thus it weakens the bending strength. This is proven by the result of the research that shows that the bending strength in 90 minute and 120 minute alkali treatment that is not higher than that reach 31,345 MPa dan 26,869 MPa. The conclution of this research are: (1) The longer of fibre alkali treatment is given, the stronger of bending strength of human hair fibre composite will be got. However, if alkali treatment is given too long (more than 60 minutes) it will decrease the bending strength of human hair fibre composite due to the damage of the hair. (2) The highest bending strength is reached when the alkali treatment up to 60 minutes that shows 43,679 MPa.

Abstract

The purpose of this research is to investigate the effect of the variation of core thickness on strength bending characteristic of cantulas? fiber sandwich composite  with the type combination C-Flute and A-Flute of cardboard honeycomb core.         Cantulas? fiber is used to make the skin by applied it in the same way and get alkali ( 2% NaOH ) in 6 hours. Hand  lay up method  is used in the production process by using fraction 40:60 resin BQTN 157 with the thickness of skin 4 mm. in  making  the combination between C-Flute and A-Flute core honeycomb used Horisontal Gelombang Dua arah ( HGD ) method  with the variation of the core thickness 10 mm, 20mm, and 40 mm. then , adhesive epoxy versamid 140 is used to glue between skin and core.  the mechanical test is conducted using bending test according to ASTM C 393 standart.  the failure observation of the bending test is done by makro photo. The result shows that the variation of core thickness influence the  strength of bending sandwich cantulas?  fiber  sandwich composite  with the type combination C-Flute and A-Flute of cardboard honeycomb core . the maximum weight of the bending sandwich composite is in the 10 mm of the core thickness with the value 14,800 MPa,  on  core shear stress and facing bending stress is in the 10 mm of the core thickness with the value 0,634 MPa and 14,271 MPa. the pattern of failure is  in the core failure, delaminasi, deformasi and in  the skin is causes of  load tensile.
