The results obtained from this research are as follows: (1) the learning media validity of the web-based learning media is declared valid with value of 85.99%, and on aspects of the material declared valid with a value of 87.7%; (2) the media practicalities of web-based learning media on the teacher's response stated the practical value of 81.7%, and based on the response of the students stated the practical value of 88%; (3) the media effectiveness of the web-based learning media was declared effective in improving student learning outcomes
Implementation of the Sun Tracker System with fuzzy logic on solar panels
Full text linkTo get the optimal solar energy requires solar Tracker system which can keep the solar panel is always perpendicular to the direction of sunlight. Solar Tracker systems using Fuzzy logic implemented using Field-Programmable Gate Array to control the movement of the frame of the solar panel with feedback to suit the direction of arrival of the Sun. Four smaller solar cells are used as sensors for controlling DC motor which is connected to the frame of the solar panels. From this study indicated that the solar panels generate greater energy by using solar Tracker systems 2.062% greater than the solar panels without a tracker
Development of project based learning tool using PLC trainer to improve creativity and self-reliance
Full text linkThis research aims to analyze: (1) quality of project based learning tool with trainer PLC, (2) the creativity of students after following the learning to use project based learning tool with trainer PLC, and (3) self-reliance learn student after following learning using project based learning tools with trainer PLC. This research is a research and development (R&D) using One Group Pretest Postest Design. The results showed that (1) the learning tools of project based learning with PLC trainer shows excellent quality with a score of 81.4%; (2) the creativity of students after implementing learning using learning tools of project based learning with PLS trainer has increased with the average value of N-gain of 0.60 criteria medium; (3) the self-reliance of the student learning increased after implementing learning using project based learning tools with PLC trainer, indicated by the average value of N-gain of 0.55 with medium criteria
Rancang Bangun Alat Meteran Air Digital Menggunakan Sensor Aliran Air SEN-HZ21WA
Full text linkTujuan penelitian ini adalah merancang meter air menggunakan sensor aliran air SEN-HZ21WA, kemudian diuji dengan cara membandingkan antara meter air analog PDAM dengan meter air Z3002. Meter air digital dapat menampilkan keluaran data berupa debit air, tekanan air, dan volume air yang mengalir pada LCD (Liquid Crystal Display). Meter air yang dikalibrasi memiliki batas pengukuran debit air yaitu 0,8-28,1 liter/menit, rata-rata kesalahan pengukuran volume air pada gelas ukur sebesar 4,5 %, dan rata-rata kesalahan debit air pada meter air Z3002 yaitu 0,063 %. Meter air yang dirancang dan meter air milik PDAM memiliki selisih rata-rata kesalahan pembacaan debit air 0,0181 liter/detik, tekanan air 0,1365 Bar, dan volume air 0,743 liter
Development of learning module through e-learning on semiconductor power components and systems inverters material
No full textLearning modules through E-Learning is designed to be able to improve the results of student learning motivation and learning. This study use Research and Development method and procedure development Plomp (preliminary research, prototyping phase, the assessment stage). The results obtained from the study of the development of the learning modules through E-Learning expressed by experts as valid media, practical response based on faculty and students, as well as effective in improving learning outcomes and motivation student learning. Based on the findings of this study it was concluded that learning modules through E-Learning can be used as learning materials on power semiconductor components and material system of inverter
Development of mobile-based e-modules integrate learning model vak (visual, auditory, kinesthetic) to foster self-reliance of learning basic programming on the students of Vocational High School
No full textThis research aims to develop mobile-based e-Module that serves as the supporting media on subjects with Basic Programming using VAK (Visual, Auditory, Kinesthetic) model learning. This research using model ADDIE (Analysis, Design, Develop, Implement, Evaluate). The results of the development of E-Module is declared valid, so worthy of use in the learning process. It is supported through results percentage of validation by an expert media amounted to 96%, the result of the validation by the percentage of material of 88%, the result of the percentage of test products amounted to 89%, the result of the percentage of trial usage of 88% and for learning independence grade and tastefully. This is supported through the research results of 80%
Analysis of Maximum Power Reduction Efficiency of Photovoltaic System at PT. Pertamina (Persero) RU III Plaju
Full text linkThe purpose of this research was to review the power output generated during the operation of the solar panels. Data that used to be taken of the Solar Power Plant or PLTS that operate PT. Pertamina (Persero) RU III Plaju observed data starting from January 2017 until December 2017 PLTS system installed in PT. Pertamina (Persero) RU III Plaju is a kind of photovoltaic grid connected (on grid). The results obtained that in manual calculations obtained fill factor of 0.7594 and output power of 250.884 Watts. Whereas the data in real time in the field fluctuating occurs at any time. This is because the weather was overcast, the lack of sunlight and shadow position (shading) that occurs due to the PLTS clouded by trees or buildings around also affects the results of the output voltage of the PLTS

No full textApplication of fuzzy logic and social media on flood hazards early warning system
Full text linkThis research aims to reduce losses that arise because of the flood in a way create a notifier flooding as flood detection. Sensors Ultrasonic sensors measure distance as can be applied as a water level detector, while the sensors used to detect flow velocity of the water flow. Research methods used in the form of literature reviews and making hardware and software using sensors SR04-HC. Applica-tion of fuzzy logic is used as a data processing of the ultrasonic sensor and flow sensor. Fuzzy logic will result in a decision on environmental conditions. With the decision made by fuzzy logic, early warning against the danger of flooding, in the form of an alarm and display the text that indicates a likelihood of flooding, as well as to social media news delivery can be carried out
