Abstract

This paper presents an experimental investigation of effect of variety lobe separation angle camshaft  to engine power. Lobe separation angle (LSA) camshaft variation used is LSA standart camshaft (104o), LSA widened camshaft (107o), and LSA narrowed camshaft (101o). Camshaft of Honda Supra X 125 is used for this research. This research at some speed of engine, these are 4000, 4500, 5000, 5500, 6000, 6500, 7000, 7500, 8000, 8500, 9000 and 9500 rpm.  Based on the data analysis it may be concluded  that the change of LSA narrowed camshaft (101o) produces a maximum power of increase. While the change of LSA widened camshaft (107o) produces a maximum power of decreases. LSA narrowed camshaft which impact on engine speed 4000 rpm ? 5500 rpm generated power falls below the standard camshaft, while the engine speed above 6000 rpm increased power over standard camshaft. Differences that occur in this research is a positive effect because the engine power can be increased on a lap top.

Abstract

The purpose of this research is to determine the factors of students learning difficulties and to find out how much each of these factors causing student learning difficulties Mechanical Engineering Education FKIP UNS Academic Year 2011/2012. The research was conducted in the Campus V Pabelan Study Program Mechanical Engineering Education FKIP UNS. The research was conducted using a quantitative descriptive. Subjects in this study were students of Study Program Mechanical Engineering Education FKIP UNS following courses in the second semester that the practice amounted to 215 students and is divided into four practice courses. Samples were taken with a proportionate stratified random sampling technique as many as 175 students. Techniques of data collection in this study is the documentation, questionnaires, and interviews. The validity of the data using the method of triangulation techniques. Test the validity of the study was conducted based on numerical correlation figures Pearson's Product Moment Correlation with SPSS 15 For Windows. Reliability test of this research using Cronbach Alpha with SPSS 15 For Windows. The method of analysis used a quantitative descriptive analysis. Based on the results of data analysis can be taken a conclusion Factors Contributing  to the difficulty of learning is divided into two major lines are a) Internal factors originating from with in the student sare divided into six indicators are physical state, a state of bodily function, intelligence, interest, motivation, and talent. b) External factors that originate from outside of a student include family factors, campus factors, and community factors are divided into ten indicators that concern the elderly, the house, the family's economic situation, lecturers, practice tools, books supporting the practice, the conditions of space workshops, hanging out friends, activities in the community, and neighborhood. However, based on several factors mentioned above the most dominant factor was the cause of learning difficulties of students interests, talents, workshop space conditions, and practices supporting books. This can be seen from the results of research that proves there are several factors that cause learning difficulties of students in practical courses.

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.
