Tes latihan siswa adalah 89,9%. Dengan demikian penelitian ini telah menghasilkan media pembelajaran Trainer Pembelajaran Mikrokontroler yang valid dan praktis Kata Kunci: Media Pembelajaran Mikrokontroler Trainer, valid dan praktis.
Tujuan pembuatan alat ini adalah untuk menghasilkan perangkat keras (hardware) dan perangkat lunak (sofware) sistem keamanan sepeda motor untuk mencegah tindak kejahatan yang dapat dikendalikan melalui perangkat smartphone dengan koneksi nodeMCU sebagai pemancar WiFi. Perancangan dan pembuatan sistem secara keseluruhan menggunakan metode reverse engineering dengan tahapan mempelajari prinsip komponen, menganalisa pemasangan komponen, membandingkan keunggulan, kelemahan produk sejenis, dan melakukan perancangan produk baru. Pada smarthpone android dihasilkan aplikasi remote motor yang telah dibuat di MIT Inventor2, yang mana terdapat dua mode sistem keamanan sepeda motor. Pertama mode aman dan yang kedua mode normal. Mode aman yaitu apabila kenoksi hotspot WiFi terputus sepeda motor akan otomatis tidak bisa dihidupkan walaupun menggunakan kunci T. Mode normal yaitu kondisi motor akan dikembalikkan seperti awal, tanpa pengaman yang bisa dihidupkan dengan kunci kontak walaupun koneksi hotspot WiFi smartphone terputus.
This study aims to ascertain the Forming Factors of Business Interest of Students in the Department of Light Vehicle Engineering at Vocational High School 2 Payakumbuh based on the internal factors: (1) Education, (2) Personality, (3) Motivation, (4) Experience, (5) Knowledge, (6) Opportunities, (7) Commitment, (8) Discipline, and (9) Leadership. This type of study was quantitative descriptive. The study population was all TKR Department students in the academic year 2019/2020 consisting of 110 students. Then, there were 85 students as samples, using the Slovin formula with a precision of 5%. Data analysis techniques are descriptive analysis and confirmatory analysis for hypothesis testing. Confirmatory analysis there are 9 independent variables analyzed through Anti Image Matrix Analysis, from the results of the research trial there are 2 variables: Education and Knowledge have MSA scores that do not meet the requirements: 0.338 <0.500 and 0.353 <0.500 so only 7 variables for further analysis. In the analysis of communilities there are 3 variables which have values below 0.500, namely Personality: 0.477, Experience: 0.306 and Commitment: 0.475, then this variable is discarded. The results of the analysis of the research trials formed a factor group of 3.128 which means that the factor was able to explain 78.2% of the 4 variables, and 21.8% of the other variables. It can be concluded that there are 4 variables: motivation, opportunity, discipline, and leadership which are the most dominant factors.
This need analysis research consists of observations and literature studies. This research aims to 1) describe student learning outcomes in the learning process. 2) find the problems faced by students in Computer and Basic Network subject. 3) find Evaluation media solutions needed in conducting the assessment. This research was a descriptive quantitative research. The subjects of this research were 31 students of Grade X TKJ in Vocational High School 2 Lubuk Basung. The data were obtained from questionnaires and analysis through the ADDIE model (Analyze, Design, Development, Implementation, Evaluation) to get conclusions. The results of the research showed that: 1) there were still many students who had not yet reached the Minimum Learning Standard. 2) the learning media used did not make it easy for students to understand the material. 3) the evaluation media used took a long time to get results.
This needs analysis research consists of field studies and literature studies. Where the purpose of this research is; 1) description of student achievement values and learning processes, 2) the uses and constraints faced by students in the use of learning media Computer Network Installation, 3) formulation of instructional media needed in learning computer network installation. This research belongs to the type of qualitative descriptive research. The subjects of this study were 29 students of Informatics Engineering Education study programs and 2 lecturers of computer network installation courses. Data obtained using a questionnaire and analysis qualitatively through stages; arranging, tabulating, analyzing qualitative data and making interpretations of the results of the analysis according to the problems and objectives of the study which then makes conclusions. The results showed that; 1) there are still many students who have not reached the score above the minimum criteria and fail in carrying out the practicum process, 2) the biggest obstacle faced by students in implementing Computer Network Installation learning is the limitations of using instructional media that are less effective to support independent learning, 3) the media that need developed for learning Computer Network Installation which is learning media based on Augmented Reality (AR).
This research is motivated by the problem of low learning outcomes in the Basic Electricity and Electronics subject at SMK Negeri 1 Sumbar. The purpose of the study was to reveal how much the contribution of the family environment and how to learn about learning outcomes. The research method used in this study is descriptive correlational. The study population 96 people and the sample 49 people. The research sample was determined using simple random sampling technique. The results of data analysis showed that (1) the family environment and the way of learning of students together contributed significantly to student learning outcomes by 37.99%. (2) family environment significantly contributes to student learning outcomes by 23.88%, (3) student learning methods contribute significantly to student learning outcomes by 26.39%. So it can be concluded that he better the family environment and effective and efficient ways of student learning, the higher the learning outcomes.

The purpose of this research is to design and make a real tool in the form of a drying cabinet for cocoa beans. Because this solution can relieve the farmers who previously drained the cocoa beans in the sun. This drying cabinet uses the Arduiono Uno 328P control and heater element as a heater. This cabinet is also equipped with a DC motor mechanical device to drive the cocoa drying container. This tool is also equipped with a DHT12 sensor which is a resistive sensor whose value changes depending on the water content of the cocoa beans. The sensor plays a role in detecting the temperature and humidity of the seeds in the cacao drying room. Then the output inverting amplifier voltage is read by the ADC Arduino UNO 328p microcontroller, which is then processed and displayed on the LCD. The test results showed that the measuring instrument made was able to measure the amount of water contained in cocoa beans in the range of water content measurement from 60% to 7.5%.

The study was to test the learning effectiveness of a program simulation method by using the trainer kit in Microcontroller System courses. The study was conducted to the students who took the microcontroller system courses in the academic year of 2013/2014. The students who took the course were divided into three groups each of which served as: (1) the experimental group, (2) control group, and (3) test instrument group. The learning outcome variables (Y2) and the awareness of thinking (Y1) served as the dependent variable; on the other hand, the motivation (X1) and the creativity (X2) served as independent variables. The data analysis was done by performing the Analysis of Variance (ANOVA) and the Multivariate Analysis of Variance (MANOVA) in order to see the differences in the learning outcomes and the level of students" thinking. The results of the study showed that there were significant differences in the level of metacognition and learning outcome competence between the group which conducted program simulation learning by employing the trainer kit and the group not employing it.
