QUALITY CONTROL DEVELOPMENT BASED ON LEAN SIX SIGMA METHOD

Clutch noise that occurs in the engine is a major cause of decreased efficiency of the engine assembly. This phenomenon has been there in such a long time in the production line, and has created a complex cause that requires a structured and systematic method in terms of handling this problem so that it can be reduced or even be eliminated. On the Problem identification, it is known that clutch noise is the result of non standard backlash. By the IPO diagram and fishbone diagram, all the non standard backlash factors are sorted into man, machine, method, and material. For the primary clutch, the value of CP = 0.02 and CPK = –0.31, indicates that the average is outside lower limit and upper limit therefore special attention must be addressed to improve it. For the secondary clutch, the value of CP = 0.22 and CPK = 0.302, which implies that the value within 0 – 1 that described the average is in between upper limit and lower limit, but there are some variance outside lower limit and upper limit. For crankcase, the value of CP = 0,79 and CPK = 1.2 signifies that the process is in control. The CPK value is greater than 1 shows that the process in in between lower limit and upper limit. DPMO target is 50,000 and the actual DPMO is 32,201 and after Lean Six Sigma was implemented, the value has been reduced to 5,487.

Nerd Up: The Rise of Nerd Media and the Co-Optation of Narrative in Advertising

Nerd Up: The Rise of Nerd Media and Co-Optation of Narrative in Advertising Advertisements are rooted in the Narrative Paradigm; they produce a good story that is probable and relevant to the consumer’s life. In the interest of relevance, advertisers often borrow narratives from cinema which increases the probability of narrative recognition among the consumers. The construction of narrative is predicated upon the ability of the advertiser to create a protagonist or spokesperson that can satisfy audience expectations and inspire the viewer to accept the brand message. Thus, classic cinematic heroes or likenesses dominate the advertising world. In light of recent economic struggles and shifting modes of production, the successful and fiscally responsible nerd has stolen the spotlight from the classic Joseph Campbell hero/adventurer. Given the rise of the nerd in cinema, advertising narratives have started to include this atypical character. The nerds that are represented in advertising are not the same as the nerds in cinema. Nerds in film are often portrayed as Jewish or African Americans; in advertising, nerd qualities are co-opted into a character that is exclusively Caucasian and stripped of all religious identifiers for mass consumption. Yet, the nerd has the ability to appeal to white audiences as well as minority demographics such as African Americans, Jews, and Homosexuals because the character embodies semiotic signifiers of difference. This makes the nerd the most versatile spokesperson because he can reach broad demographics without incriminating the brand

THE EFFECTIVENESS OF CONTEXTUAL TEACHING AND LEARNING TO TEACH READING COMPREHENSION VIEWED FROM STUDENTS’ INTELLIGENCE (An Experimental Study in SMPN 14 Surakarta in the Academic Year of 2009/2010)

The objectives of the research were to examine: (1) whether the contextual teaching and learning method was more effective than grammar translation method in teaching reading for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010; (2) whether the students having high intelligence quotient had better reading comprehension than those having low intelligence quotient for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010; and (3) whether there was an interaction between teaching methods and the students’ intelligence in teaching reading for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010. The research was carried out at SMPN 14 Surakarta, from November 2009 to August 2010. The method used for the research was experimental study. The population of the research was the eighth grade students of SMPN 14 Surakarta. The sampling technique used was cluster random sampling. The sample of the research was two classes; they were experimental class which was taught using contextual teaching and learning method and control class which was taught using grammar translation method. The number of sample used in the research was 36 students from experimental class and 36 students from control class. The technique of collecting data was documentary and test technique. The first was used to collect the data of students’ intelligence scores. The latter was used to know the students’ ability in reading comprehension. The reading test was in the form of multiple choices with four options. It had been tried out first, in order to know the validity and reliability of instrument. Meanwhile, to analyze the data, Multifactor Analysis of Variance (ANOVA) test of 2x2 and Tukey test were used. Before conducting the ANOVA test, normality and homogeneity test were conducted. The result of data analysis showed that: (1) contextual teaching and learning method was more effective than grammar translation method in teaching reading for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010; (2) the students having high intelligence had better reading comprehension than those having low intelligence for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010; and (3) there was an interaction between teaching methods and students’ intelligence in teaching reading for the eighth grade students of SMPN 14 Surakarta in the academic year of 2009/2010. Seeing the result of the research, it could be concluded that contextual teaching and learning method was an effective method to teach reading comprehension. The research also showed that the effect of teaching methods depended on the degree of intelligence. Therefore, the English teachers were recommended to apply the seven components of contextual teaching and learning method in the classroom, particularly in teaching reading comprehension
