Bulletproof vests are outer clothing commonly used to protect military personnel from projectile attacks and explosion material distributions. In this study the bulletproof vests were made of composite particles composed of an epoxy matrix with a Hollow Glass Microsphere (HGM) amplifier and carbon fiber. The study was conducted by doing simulation analysis using Finite Element Method in accordance with NIJ (National Institute of Justice) of American Standard 0101.06 for class IIIA weapons category. The thickness of bulletproof vest was varied from 1 to 20 mm in order to obtain the optimal thickness. After obtaining optimal thickness of the bulletproof vest, then verification with experimental will be done to validate the simulation result. The results showed that the increase in the thickness has increase the toughness and rigidity of a bulletproof vest. A bulletproof vest with a thickness of 20 mm able to absorb bullet energy of 348.27 Joule and kinetic energy which passed the body of 138, 77 Joule with a penetration depth of 5.54 mm. Thus, it has met the NIJ Standard 0101.06 standard of U.S. The energy passed to the body is smaller than 170 Joule.

Research is included into the type of descriptive study using quantitative and qualitative approaches. The research procedure includes stage 1) initial observation, 2) preparation, 3) implementation, 4) evaluation, and 5) final results. The subjects in this study were the second semester students of Mechanical Engineering Study Program, totaling 24 people. Data collection techniques used 1) test questions, 2) interviews, 3) documentation, and 4) field notes. Data analysis techniques mastery level of the material were analyzed using the percentage formula. Interview data were analyzed in stages 1) reducing data, 2) presenting data, and 3) summarizing data. Instrument documentation and field notes were analyzed narratively. The results of data analysis on the level of student mastery of composite material shows that the group of students in the category of mastery is very mastering (SM) 0 students (0%), the category of mastery mastering (M) is 9 students (23.68%), the category of mastery is less mastering (KM ) 16 students (42.11%), mastery category not mastered (TM) 13 students (34.21%). Students who mastered the mastery-1 category were 15 students (39.47%), who mastered the mastery-2 category by 22 students (57.89%), who mastered the mastery-3 category by 9 students (23.68%) and categories mastery-4 as many as 0 students (0%). Interview results obtained by some students 'mistakes in mastering composite material courses, namely a) errors in the use of formulas or concept errors, b) errors in algebraic fraction operations, c) students' lack of attention to the tests conducted, d) errors in inputting parameter values, e) errors in the operation of exponential numbers, f) errors in formulating problems in the form of formulas (mathematical modeling), and g) principle errors.

Students graduating with a minimum score of C in the 2018/2019 even semester is 47%. Given the importance of the course objectives and the low learning outcomes achieved, a learning approach is applied which is expected to create active learning for students. To present active learning, the learning approach used must be familiar with students' daily lives. One learning approach that can emulate the daily lives of students is the Contextual Teaching and Learning (CTL) learning approach. The formulation of the problems in this study are a) is the application of CTL able to improve the learning outcomes of students in semester II of the Computer Engineering Study Program in Discrete Mathematics courses ?, b) how do lecturers manage learning with the CTL approach ?, and c) how are student learning activities using CTL? The purpose of this study was to a) determine the improvement of student learning outcomes, b) to determine the ability of lecturers to manage learning activities, and c) to determine student activities in learning. The research approach used in this research is quantitative and qualitative approaches, while the type of research is classroom action research (PTK). The subjects of this study were 16 students in the second semester of the Computer Engineering Study Program. The data collection techniques used in this study were a) test questions, and b) observation sheets. The study consisted of 2 (two) cycles, where the first cycle consisted of 3 meetings, while the second cycle consisted of 2 meetings. The results showed that the ability of lecturers to manage learning in cycles I and II was in a good category and the ability of lecturers to manage learning had increased when compared to cycle I to cycle II, from 3.88 to 4.06. Student learning activities in cycle II increased when compared to cycle I. The results of the first cycle test showed that 11 students completed, while in cycle II the results obtained 12 students completed. The percentage of student learning completeness during the first cycle to the second cycle was 68.75% and 75%. The increase in student learning completeness between cycle I and cycle II is 75% - 68.75% = 6.25%.

Mathematical Association material becomes difficult for students to learn since it is described in the form of set-forming notation and story-based questions (applied). Moreover, they find it difficult to determine the number of subsets with several determined members. The author's observations while teaching at the South Aceh Polytechnic Computer Engineering Study Program for the 2018/2019 academic year obtained data that students did not master Discrete Mathematics subjects, especially the material of the Association. This can be seen in daily assignments, midterm exams, and final semester exams. The author as a lecturer in the Study Program was disappointed with the results obtained. The approach and type of this research is a quantitative approach and a pure experimental type of research. The research sample of the second-semester students of the South Aceh Polytechnic Computer Engineering Study Program for the 2019/2020 academic year was 16 students. The research data was the test scores collected from students. The instrument in this study was a test question. The data collection technique in this research is a written test. Data analysis used t-test at a significant level α = 0,05, dk = 4, with standard value of = 69. Based on the analysis gained and . Thus, the result turns out or 1.83 > 1,75. Thus it is concluded that the mastery of Computer Engineering Study Program students at the Polytechnic of South Aceh for the 2019/2020 academic year in understanding the set material has reached a level of success.
