Abstract

Learning mathematics at SMA Negeri 7 Palu is generally dominated by teachers, causing low student learning outcomes. The purpose of this study was to improve the results of learning mathematics in the matter of trigonometry ratios in Cartesian coordinates and angles of trigonometric relations through the application of the cooperative script learning method. This research is a class action research (PTK) in class X IPA.4 SMA Negeri 7 Palu, totaling 32 students. This research was conducted in three cycles and data was collected through observation sheets from teacher activities and student activities, as well as action results tests. The results of the research on teacher and student activities increased from cycle I to cycle II and cycle III and were in the good and very good categories. Analysis of learning outcomes obtained from student data in cycles I, II and cycle III experienced an increase, the classical absorption value of cycle I (73.51%), and cycle II (74.59%) and cycle III (80.22%) as well as The classical completeness obtained from the data of students in cycle I, II and cycle III has increased, the classical absorption value of cycle I (59.38%), cycle II (71.88%) and cycle III (84.38%). Based on the indicators of the success of this study, if the percentage of classical absorption and classical mastery reaches 80%, it can be concluded that the application of the cooperative script learning method can improve mathematics learning outcomes in the matter of trigonometry ratios in Cartesian coordinates and angles of trigonometric relations in class X IPA.4 SMA Negeri 7 Palu.

Abstract

Motor travel serves as a steering and braking system, driving the unit forward, backwards and to the side with the help of a hydraulic system. The hydraulic system plays a very important role in the operation of the machine. The fundamentals of hydraulic and advanced hydraulics, and applied failure analysis support the knowledge of engineering students. The method used is to carry out the disassembly and analysis of the travel motorbike with the aim of identifying the damage that occurred. Visual analysis of traction motors, head/valves, brake valves, brake pistons. These components can be reused after cleaning the components. There is also such a type of damage to traction motor components as wear and tear. This wear is found in retaining shoes, port plates, cylinders, pistons, camshafts, and shafts. . After visual analysis, the next step is measurement. The measured part is a spring. The results of the analysis proved that the measurement of this spring does not correspond to the information provided in the literature.

Abstract

One of the Study Programs in the Poliban Mechanical Engineering Department is the Heavy Equipment Study Program. One of the courses contained in the Heavy Equipment Study Program Curriculum is Basic Welding which is taken in semester IV with a weight of 2 credits. To find out whether students really master their field, a reliable evaluation tool is needed, because this evaluation tool must really be able to reveal whether the results of student practice have met the criteria or not. The purpose of this study was to determine the quality of the welds on the practical results of semester IV students of the Mechanical Engineering Department, Heavy Equipment Study Program, using tensile and macro testing. It is hoped that the target of student lectures can be achieved. This research took the population of the Poliban Heavy Equipment Study Program Semester IV. While the research sample was taken 18 students who carry out welding practice. Based on the yield stress obtained, there are 2 specimens or the equivalent of 11.11%, which is below the standard of the Yield Strength of ST-37 steel or the equivalent of AISI 1045, which is ≥ 310 N/mm2, so the percentage of acceptable student welding results is 88. 88%. Based on the results of the visual inspection, there were four specimens that broke off in the weld area or equivalent to 22.22% of the test results, so that the percentage of acceptable student welding results based on the visual inspection results was 77.78%.

Abstract

Physics learning at SMA Negeri 5 Palu is generally dominated by teachers, causing low student learning outcomes. The purpose of this study was to improve the learning outcomes of physics on work and energy through the application of the Thinking Aloud Pair Problem Solving (TAPPS) learning model for class X MIPA students. 1. This research is a class action research (CAR) in class X MIPA students. 1 SMA Negeri 5 Palu with a total of 33 students. This classroom action research was conducted in two cycles with material on work and energy. In this study, data were collected through observation sheets from teacher activities in managing the TAPPS learning model and student activities, as well as tests of the results of each cycle's actions. From the results of the study showed that the activities of teachers and students experienced an increase from cycle I to cycle II and were in the very good and very good categories. Based on the analysis of learning outcomes, it was obtained that student data from cycle I to cycle II increased, where the classical absorption value of cycle I was 66.88%, and cycle II was 79.19%, an increase of 12.31%. For classical learning mastery it increased by 21.21% with the classical mastery value of cycle I was 60.61% and cycle II was 81.82%. Based on the indicators of the success of this study, namely if the percentage of classical absorption was 80% and classical completeness was 80%, it was concluded that the application of the TAPPS learning model could improve the learning outcomes of physics on work and energy in class X MIPA students. 1 SMA Negeri 5 Palu.

Abstract

Wheel loader is one of the heavy equipment units used to move materials. One of the parts of concern for the machine unit is the differential which functions to move the rotational power from the propeller shaft to the rear wheel axle. This study aims to find the cause of damage to the differential components of Caterpillar's 914G unit. The method used is library research which begins with taking data from the Service Information System (SIS) as standard data and various modules related to the object of research, field observation by disassembling, visual inspection of objects, and ending with measurements that will be compared with standard data. The results of this study showed that measurements on the backlash component between the bevel gear and pinion shaft were 0.31 mm with standard specifications of 0.18-0.36 mm (in spec), damage to the ring gear due to contact stress fatigue wear, scratches due to abrasives on the side gear, and there was spider gear damage due to contact stress fatigue wear.
