Variable speed control of wind turbine generator systems have been developed to get maximum output power at every wind speed variation, also called Maximum Power Points Tracking (MPPT). Generally, MPPT control system consists of MPPT algorithm to track the controller reference and generator speed controller. In this paper, MPPT control system is proposed for low speed wind turbine generator systems (WTGs) with MPPT algorithms based on optimum tip speed ratio (TSR) and generator speed controller based on field oriented control using type-2 fuzzy system (T2FS). The WTGs are designed using horizontal axis wind turbines to drive permanent magnet synchronous generators (PMSG). The simulation show that the MPPT system based optimum TSR has been able to control the generator output power around the maximum point at all wind speeds.

Based on the researcher's experience in taking PLC and Pneumatic courses in the fifth semester of 2018, the engineering faculty of the State University of Padang still uses manual books in printed form assisted by media in the form of power points where the media is less interactive and does not increase interest student self-study. Advances in information technology have enabled researchers to develop learning in changing the presentation of teaching materials, in this case, printed modules, into modules that are packaged in digital format, or known as electronic modules (e-modules). The research method used is R&D (Research & Development) and the model is 4D (Define, Design, Develop, and Disseminate). The research was conducted on students in the PLC and pneumatic courses at Padang State University. The questionnaire used in the study was a validation questionnaire and a student practicality questionnaire. In the distribution of validation questionnaires, the average results were obtained with a very valid category, on the distribution of practicality questionnaires to students, the scores were obtained in the practical category and some gave values in the very practical category. With the average value obtained, the module media is said to be very practical. Based on the results of the research data, it is stated that the module is very valid and practical.

This research is motivated by the lack of active role of students in the learning process due to the limited learning media used in learning. Lecturers are more likely to use printed learning resources that are not able to present the material required for simulation so that it is difficult for students to understand and is not interactive yet. Therefore, it is necessary to develop interactive learning media using Adobe Flash CS6 software which is designed to help students in more active learning. This study aims to produce interactive learning media using adobe flash CS6 software that is valid and practical. This study uses a Research and Development (R&D) method with a 4D development model which is divided into the stages of defining, designing, developing, and disseminating. The subjects of this study were students of semester 3 class 2TEIA Diploma-4 Electrical Engineering, Padang State University, 2020/2021 academic year. Based on the research results, testing the validity of interactive learning media obtained an average value of 0.81% with the valid category. The results of the practicality test for lecturers were obtained by 92.6% in the very practical category and the results of the practicality test by students were obtained by 83.4% with the practical category. It can be concluded that the resulting interactive learning media using Adobe Flash CS6 software is valid and practical for use in the teaching and learning process in Digital Engineering subjects.

This study aims to determine whether the Creative Problem Solving learning model can improve the competence of class XI TITL students at SMK Negeri 1 Lembah Melintang West Pasaman. This research is classroom action research. The research was carried out in each cycle of three meetings. Each cycle consists of four stages, namely planning, acting, observing, and reflecting. Data collection used the pretest, posttest instrument, last year's student score document to determine the increase in cognitive aspects, observation sheets to determine the increase in affective aspects, and student activity sheets to determine the increase in psychomotor aspects. The data analysis used is descriptive quantitative. The success criteria established for each assessment indicator reached a class average score with a minimum score of 76. The results showed that with the application of the Creative Problem Solving learning model, the competence of student groups had increased. This can be seen with an increase in the affective aspect of the first cycle, the average value of 53.46%, and an increase in the second cycle of the third meeting to 88.68%. The cognitive aspect of students has increased, seen from last year's class score of 63.83, decreasing in posttest cycle 1 to 55.1, increasing in posttest cycle II to 80.1. The average psychomotor score also increased, the psychomotor score in the first cycle of the first meeting was 81.2, increasing to 91.9 in the second cycle of meeting 3. The results of the student's learning achievement had met the minimum completeness criteria.

Solar panel merupakan sumber energi terbaru yang efisien dan ramah lingkungan. Prinsip kerja solar cell yaitu melewati efek fotolistrik dimana bahan-bahan tertentu menciptakan aliran listrik pada cahaya matahari dan menghasilkan arus searah (DC). Sistem pengisian baterai solar cell dengan memanfaatkan cahaya matahari, Watt Peak (WP) adalah satuan yang menyatakan daya produksi tertinggi yang dapat dihasilkan oleh panel surya per satuan waktu. Satuan ukuran panel surya ini didapat dari jumlah produksi daya yang didapat ketika matahari bersinar dengan tingkat radiasi tertinggi. Penyinaran matahari tidak selalu stabil dalam satu hari, matahari mengalami puncak hanya 3 – 5 jam/hari tergantung lokasi. Waktu ideal panel surya menghasilkan daya terbaik (Pmax), yang ditunjukan dalam Wp. Sedangkan untuk menghasilkan daya yang maksimum dibutuhkan pengontrolan tracker panel surya diantara nya maximum power point tracker (MPPT). Dengan menggunakan pengontrolan tracker panel surya yaitu maximum power point tracker (MPPT) maka daya keluaran panel surya akan semakin maksimum.

Nilai tahanan pentanahan yang baik agar dapat terhindar dari gangguan adalah < 5 Ω. Penelitian ini bertujuan untuk mengukur tahanan pentanahan dan menganalisa nilai tahanan serta merancang sistem pentanahan. penelitian dilakukan di Gedung Olahraga Universitas Negeri Padang. Penelitian ini menggunakan metode 3 titik dengan Earth Tester untuk mendapatkan hasil nilai tahananya. Berdasarkan pengukuran yang dilakukan didapatkan rata-rata nilai tahanan pentanahan yang ada di Gedung Olahraga Universitas Negeri padang sebesar 26.54 Ω .nilai tahanan pada Gedung Olahraga Universitas Negeri Padang ini sangat tidak layak, sehingga untuk memperbaiki nilai tahanannya maka dilakukan perancangan ulang. Jenis tanah yang ada di sekitar Gedung Olahraga Univeristas Negeri padang merupakan tanah rawa yang memiliki nilai tahanan jenis tanah sekitar 10-30 Ω. Untuk mendapatkan angka tahanan yang bagus maka dibutuhkan pentanahan yang memiliki kedalaman 12 Meter dan dibuatkan sebuah kotak kontrol supaya memudahkan dalam melakukan pemeliharaan sistem pentanahan.

Setiap gedung yang memiliki instalasi listrik baik untuk penerangan serta labor komputer dan perangkat elektronik harus memiliki dan terkoneksi dengan sistem pembumian. Sistem pembumian ini bertujuan agar manusia ,instalasi listrik, peralatan listrik dan komputer pada bangunan tersebut dapat terhindar dari bahaya konsleting listrik yang disebabkan oleh adanya sambaran petir. Menurut standar peraturan umum instalasi listrik (PUIL) untuk mengindari bahaya sambaran petir pada sebuah gedung dibutuhkan nilai resistansi petanahannya < 1Ω.Beberapa faktor yang memperngaruhi nilai sistem pentanahan diantaranya jumlah batang elektroda yang ditanam, kedalaman menanam elektroda ,jarak antar elektroda yang ditanam, kondisi jenis tanah dan ukuran batang elektroda. Pada pengukuran nilai tahanan grounding di Gedung Fakultas Ilmu Keolahragaan Universitas Negeri Padang menggunakan elektroda batang dengan diameter 5/8 inch atau 0,0158 m didapatkan nilai hasil pentanahannya sebesar 27,5 ohm dengan kedalaman elektroda 0,5 meter dan pada kedalaman 1 meter didapatkan nilai pentanahan sebesar 16,21 ohm. Untuk mendapatkan nilai tahanan grounding yang sesuai dengan standar peraturan umum instalasi listrik (PUIL) yaitu < 1Ω maka dilakukan analisa dan perhitungan dari nilai resistansi tanah yang telah di ukur dan didapatkan hasil perancangan sistem grounding di gedung Fakultas Ekonomi dirancang dengan metodhe multi rod dengan memasang tiga buah elektroda batang secara paralel pada kedalaman 8 meter..
