One of Sustainable Development Goals (SDGs) declared by United Nation is Climate Action. Integrated climate change measurement is one of the point in this goal. The solution in this form is low cost and open source hardware to monitor weather and air quality real time. This study goals is developing Arduino platform to monitor wind speed, air temperature, air humidity, and smoke. All circuit board, electronic component specifications, and programming software are open source and freely available for anyone to use and modify. Inexpensive sensors and Arduino Uno were used to develop low cost system. This system send data to Thingspeak as Open Internet of Things (IoT) platform which provide real time data collection, data processing, and data visualization to users. This system provide a low cost solution (system cost around one million Rupiah) to monitor weather and air quality that easily deployed in the desired geographical area. The results are plotted in graphs to ease the users monitor data both locally and remotely. This system use Arduino Uno as main processor, Real Time Clock DS3231 to provide time information, anemometer to provide wind speed, DHT22 used as humidity and temperature sensor, MQ-2 used for smoke detection and CO level, and SIM900 as GSM shield for sending data to server. Results of measurements demonstrate the usefulness of this system in weather and air quality monitoring.

The DC motor is one component of robot, the main function of a DC motor is as a driver, whether it's a legged robot or not, as used in a mobile robot. DC motor control is necessary to be one thing that must be considered, because if the motor does not run properly, it will renew the purpose of the motor when it is created. The ability to control a DC motor is needed when building a robot. Many things can affect a person’s ability to design DC motor controller, one of which is the development of science, especially computer science, the use of algorithms to achieve the effectiveness of DC motor movements is very necessary today, so that the robot can move well and according to what is desired. The algorithm requires some information from the system that is built either as input or output so that the algorithm can perform the control process properly. in this study the motor speed controller circuit has been designed using transistor IR630 (n-channel mosfet), in this study the motor speed controller circuit has been designed using transistor IR630 (n-channel mosfet), the potentiometer is used as an analog input on the microcontroller and then converted to a PWM signal which will be used as input to the controller circuit to drive a DC motor. In the tests that have been carried out, the results obtained that the motor can be controlled properly, the use of resistors with a certain amount (220 ohms) can increase the resulting motor rotation and at what voltage the motor starts to spin at a voltage of 0.436 volts, and continues to increase and the maximum voltage recorded at 6.40 Volts.

Pengukuran suhu, kelembaban, dan kecepatan angin sangat penting untuk dilakukan di pulau sebagai informasi cuaca kepada masyarakat. Sistem monitoring ditambahkan perangkat pengiriman data menggunakan kartu GSM agar dapat ditampilkan datanya ke dalam dashboard platform online. Penelitian ini bertujuan melakukan pengembangan sistem monitoring kecepatan angin, suhu, dan kelembaban berbasis web yang dapat diterapkan di daerah kepulauan, pemantauan data secara realtime yang terkirim ke platform, dan pengukuran konsumsi daya pada perangkat. Metode penelitian ini dilaksanakan dengan melakukan studi literatur,  observasi, perancangan, dan pengujian sistem. Pada penelitian ini GSM Shield SIM900 digunakan sebagai perangkat pengiriman data, DHT22 sebagai perangkat sensor suhu dan kelembaban, perangkat anemometer sebagai pembaca kecepatan angin, platform Thingspeak sebagai penampil data, dan micro SD Card sebagai penyimpanan data cadangan. Hasil penelitian didapatkan bahwa pengembangan sistem monitoring suhu, kelembaban, dan kecepatan angin telah berhasil dilakukan dengan pengiriman data menggunaakan GSM yang ditampilkan ke dalam platform Thingspeak. Data yang tidak terkirim ke server diduga karena kualitas sinyal GSM pada saat pengiriman data tidak cukup kuat atau karena adanya timeout. Sistem monitoring ini menghabiskan daya sebesar 0,977 Wh.

Pendidikan pada usia dini menjadi sebuah fenomena menarik pada saat ini di Indonesia,dapat dilihat dari menjamurnya taman pendidikan untuk anak yang belum  bisa masuk sekolah. Provinsi Kepulauan Riau (Kepri) yang lokasinya berbatasan langsung dengan Gerbang Internasional Singapura dan Malaysia secara tidak langsung diminta untuk mampu berkompetisi secara secara softskill dan hardskill. Untuk menghadapi kesempatan tersebut dan menciptakan generasi yang mampu bersaing secara global, jurusan Teknik Elektro Universitas Maritim Raja Ali Haji (UMRAH) melalui tridharma perguruan tinggi, bekerjasama dengan bagian Corporate Social Responsibility (CSR) Banyan Tree Hotel and Resorts Bintan, menghasilkan sebuah program bernama Edutech for Children (EfC). EfC adalah program untuk meningkatkan kemampuan siswa berpikir secara kritis dan analisis pada usia dini melalui pengenalan proses perancangan rekayasa dan pelatihan pola pikir insinyur untuk siswa di sekolah. Dimulai dari proses etnografi, brainstorming, menentukan permasalahan dan solusi utama dan merancang menggunakan perangkat lunak 3 dimensi Autodesk inventor. Sebuah inovasi yang merupakan luaran dari proses desain rekayasa adalah merupakan hasil dari proses rancangan yang berbasiskan kepada pengguna dengan menggunakan pendekatan etnografi, oleh sebab itu melalui pelatihan yang diberikan siswa akan diajak untuk mampu memahami bahwa sebuah inovasi tersebut membutuhkan integrasi kemampuan berpikir secara luas terhadap permasalahan yang ada di masyarakat. Dengan kegiatan ini didapatkan hasil memuaskan yang dibuktikan dengan meningkatnya kemampuan teknis dan munculnya pola pikir inovatif sehingga siswa mampu untuk menemukan dan merancang teknologi yang sesuai untuk kebutuhan setempat. Kata kunci: Berpikir, Kompetisi, Kemampuan, Siswa, Teknologi ABSTRACT Education at an early age is an interesting phenomenon at this time in Indonesia, can be seen from the mushrooming of educational parks for children who have not been able to go to school. Riau Islands Province (Riau Islands) whose location is directly adjacent to the International Gates of Singapore and Malaysia is indirectly requested to be able to compete in soft skills and hard skills. To face this opportunity and create a generation that is able to compete globally, the Department of Electrical Engineering, Raja Ali Haji Maritime University (UMRAH) through the three-tridharma of higher education, in collaboration with the Corporate Social Responsibility (CSR) section of the Banyan Tree Hotel and Resorts Bintan, produced a program called Edutech for Children (EfC). EfC is a program to improve students 'ability to think critically and analyze at an early age through the introduction of the engineering design process and training of engineers' mindsets for students in schools. Starting from the ethnographic process, brainstorming, determining the main problems and solutions and designing using Autodesk Inventor's 3-dimensional software. An innovation which is an outcome of the engineering design process is the result of a design process based on the user using an ethnographic approach, therefore through training provided students will be invited to be able to understand that an innovation requires the integration of broad thinking skills towards problems exist in the community. With this activity, satisfying results are evidenced by increasing technical ability and the emergence of innovative mindsets so that students are able to find and design technologies that are suitable for local needs.
