The objectives of this research are to investigate: (1) the effect of the number of inlets on the toughness in the pulley; (2) the effect of the number of inlets on the toughness in the casting of pulley from gray cast iron; (2) the effect of the number of inlets on the hardness in the casting of pulley from gray cast iron; and (3) the effect of the number of inlets on the micro structure in the casting of pulley from cast iron and sand mold. This research was conducted in the Engineering Material Laboratory of Diploma Program of Vocational School, Gadjah Mada University. Three types of number of inlet were used in the casting of pulley from gray cast iron, namely: one-inlet type, two-inlet type, and three-inlet type by using wheel (ring) gate in the casting inlet system. The parameter of input in the data analysis consisted of the tests on toughness, hardness, and micro structure. The data of this research were analyzed by using the descriptive data analysis in which the results of the experiment were observed directly and analyzed and then the conclusion of this research was drawn. The results of this research are as follows: (1) the toughness of pulley with one-inlet type is higher due to slow congealment in such a way that more ferrite is collected; (2) ferrite has soft and ductile characteristics; (3) the hardness of pulley with three-inlet type is 205.8 VHN which is higher than that of pulley with two-inlet type (201.8 VHN) and that of pulley with one-inlet type (196.8 VHN); (4) the hardness of pulley with three-inlet type is higher due to quicker congealment in such a way that the perlite formed is spread more evenly and the amount of graphite formed is getting smaller; (4) perlite has hard and brittle characteristics. The microstructure of pulley specimen in this research is hard and strong perlite matrix. The structure of graphite and ferrite in the pulley specimen with one-inlet type is greater in amount than that in the pulley specimen with two-inlet type and that in the pulley specimen with three-inlet type. On the basis of the results of the research, a conclusion is drawn that the value of toughness of pulley with one-inlet type is 0.055 J/mm2 which is greater than that of toughness of pulley with two-inlet type (0.053 J/mm2) and that of toughness of pulley with three-inlet type (0.052 J/mm2).

The aims of this research were: (1) To examine the effects of variated composition of corncob powder, brass powder (Cu-Zn), magnesium oxide (MgO), and polyester resin composites on the friction coefficient value in brake pads braking performance test by using Prony brake engine; (2) To investigate which brake pads compositions of corncob powder, brass powder (Cu-Zn), magnesium oxide (MgO), and polyester resin composites that has the highest friction coefficient value; (3) To compare the braking performance of corncob powder brake pads with Nissin brake pads. This research used descriptive and quantitative method. The sampling process was done by making three variations of brake pads compositions. Data were obtained by braking performance test using Prony brake engine then calculated using Prony brake formula. The calculation results were presented in tables and graphs, and then analyzed. The conclusions based on this research were: (1) The variated material compositions of brake pads gave effects on the friction coefficient value of the brake pads. This was indicated by the difference values of friction coefficient values for each brake pads compositions. The friction coefficient value of brake pads composition I which consisted of 20% corncob powder, 40% brass powder, 20% MgO, and 20% polyester resin was 0.342. The friction coefficient value of brake pads composition II which consisted of 30% corncob powder, 30% brass powder, 20% MgO, and 20% polyester resin was 0.395. The friction coefficient value of brake pads composition III which consisted of 40% corncob powder, 20% brass powder, 20% MgO, and 20% polyester resin was 0.354; (2) The most optimal brake pads composition which had the highest friction coefficient value was composition II 0.395 with a composition of 30% corncob powder, 30% brass powder, 20% MgO, and 20% polyester resin; (3) The brake pads with corncob powder material had a good braking performance. The friction coefficient values of all brake pads with corncob powder compositions were higher than Nissin brake pads.

This study was conducted because of the differences in students' interest in the practice and theory subjects. Students are more interested in the practice than theory lessons. According to Muhibbin Syah interest is a great inclination toward something. Interest is something that are influenced by internal factors and external factors in human beings. The purpose of this study was to describe the factors that influence students' interest towards practical subjects and the reasons why students are less enthusiastic on the subjects of theory. This study was held at SMK Negeri 2 Karanganyar. This study used a qualitative research with a descriptive approach. Sources of data in this study were the teacher, the eleventh grade students and learning environment in SMK N 2 Karanganyar. The data collection technique were using the questionnaire, observation, interviews, documentation or records. The validity of the data were using triangulation methods and sources. Analysis of the data in this study was the interactive analysis model. The results showed that some of the internal factors that affect student interest are attention span which is high with 57,14%, curiosity which is high with 54.76%, motivation which is very high with 52.38% and the students? needs which is high with 70.24%. External factors that affect student interest are support from parents which is high with 61.91%, teachers which is high with 66.67%, friends which is 53.57% or high, school?s facilities is moderate with 40,48% and social environment which is high with 64.29%. The reason students are less interested in the theoretical lessons are (1) teachers, teachers are often too monotonous in teaching, are underestimating students, and are too rapid in conveying the learning materials, (2) motivation, most of the students assume the practice is more important, (3) friends, students are easily affected to their friend demeanor.
