Abstract

The problem faced by students is the difficulty of understanding on metal casting topic in the lesson of Materials Technology which is conducted by lectures only. The research objective is to find out the improvement of score on metal casting topic for 1G students from Mechanical Engineering Department, State Polytechnic of Malang (Polinema) in odd Semester, Academic Year 2016/2017. Research method were facilitation of applied metal casting through pretest of metal casting, added a description of the design and modification of metal mould for Aluminium, visit to a home industry of Aluminium casting, students practice of Aluminium casting in a home industry, student groups presentation and discussion in the subtopics of (1) design and mould manufacture, (2) Aluminium casting practice, and (3) tensile testing with cast Aluminium specimen, as well as posttest on metal casting. The research result is an increasing in average score from 46.56 to 53.6 (22%) that means by adding the practice to the theory involved is increase a significant impact on understanding of Aluminium casting for students.

Abstract

The number of blades factor and the blade angle factor on the propeller turbine will be affect to the performance, and one of these factors is dominant affected for the turbine performance. To optimize the design of propeller turbines, must be known the factors that most influence its performance. This study aims to investigate the significance test of difference value in shaft power due to the number of blade factor and the blade angle factor, and to determine the most dominant influence of these factors. Hypothesis test method of these factors on this study using analysis-of-variance or ANOVA with SPSS 17.0 software. The results of this study indicate the significant test in shaft power value in the number of blades factor and the blade angle factor, and there is a relationship between both factors influences in shaft power value significantly. This study also shows the blade angle factor has the most dominant effect in shaft power value, beside the number of blade factor.

Abstract

A field evaluation was conducted to study the genotypic correlation between yield potentials and resistance level to the late leafspot of peanut. The experiment was carried out at Muara experimental-field from October 1994 to January 1995 using 100 genotypes with natural late leafspot inoculation. The result showed that the resistance level to late leafspot, wish was quantitatively reflected by the fresh-leaves percentage has negative genotypic correlation with total and filled-pod numbe1: The negative genotypic correlation were also found between resistance level and the weight of total pod, filled pod, as kernel, although not significant.
