Problems in accuracy top throws are often carried out by students in softball games so the need for alternative methods to improve them are the method massed practice and distributed practice. This study aims to find out: (1) effect of learning methods massed practice and distributed practice on the accuracy in conducting top throws on male students of extracurricular softball class X at Bhina Karya Karanganyar Vocational School 2014/2015 Academic Year, and (2) the influence between the method of practicing massed practice and distributed practice on the accuracy in carrying out throws on male students. This research is an experimental research using pre-test-post-test design with technique pairing ordinal. The sample groups of this study were 30 male students of extracurricular softball class X. Data analysis used different tests: (1) before being given treat; (2) after being treat; and (3) differences in percentage increase between groups. The results of the study are (1) the effect of learning massed practice and distributed practice on the ability of the accuracy of throws on balls of softball, with the results of count = 4.740 > t table = 2.145; and (2) the learning method massed practice has a better effect than the exercise of distributed practice on the ability to accurately throw balls of softball, with an increase massed practice = 29,054%> distributed practice = 14,085%. The conclusions of the study are (1) there are differences in the influence of learning massed practice and distributed practice on the ability of the accuracy of the throws on balls softball; and (2) learning method massed practice has a better effect than exercises including distributed practice on the ability to accurately throw balls of softball.

<p><em>This study aims to (1) produce a practical teaching material in the form of a practicum e-module for advanced fuel motor practice courses in the Mechanical Engineering Education Study Program which is declared feasible (2) find out the practicality of practicum e-modules in advanced fuel motor practice courses in the Mechanical Engineering Study Program.This research uses the type of research development or Research and Development (R&amp;D). The development model used is the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The instruments used in this study included practicum e-module requirement sheets, practicum e-module validation sheets by experts, research sheets for lecturers in advanced fuel motor practice courses and student response sheets. Trials of the practicum e-module product were carried out for students of the Mechanical Engineering Education study program class of 2021 who are currently taking an advanced fuel motor practice course. Data analysis used in this research is descriptive quantitative and descriptive qualitative.Based on the results of the analysis of the validation sheet by the experts, it was found that the practicum e-module was declared feasible to use with a score of 88.8% for the results of material experts in the very feasible category, 86.4% for media experts in the very feasible category, and linguists showing a percentage score of 97.5% very decent category. Based on the results of the analysis of the practicum e-module practicum sheet by student responses and the assessment of lecturers supporting advanced fuel motor practice courses, it shows that the practicum e-module is stated to be practical with an average result of student response percentage scores of 88.9% in the very practical category and the assessment of supervising lecturers shows a score of 85.3% with the very practical category. So that the practicum e-module is declared feasible and practically used by students as teaching material in supporting the learning of advanced fuel motor practice course.</em></p>
