Research has been carried out on the use of the Internet of Things in smoke density levels monitoring and camera movement control. Internet of Things as long distance communication for monitoring and control systems. In this research, the system can detect smoke levels and can monitor it via an android phone, besides this system is equipped with camera movement control so that the camera position can be controlled remotely to be positioned towards the center/source where smoke is detected, so this system is needed as building and industry security as a fire prevention. This study uses a smoke density detection sensor type MQ-2, Arduino Uno as a controller, Esp8266 as a Wifi module and a servo motor as a camera driver. The results of the tests that have been carried out prove that the system has been successfully integrated and works according to the target, which is to detect the concentration of smoke and monitor remotely via an android phone and camera movement control properly.
Crisis of energy that hit the world had an impact on high world crude oil prices, thus directly affecting economic activity. The wealth of energy resources, especially the new and renewable energy sources that we have, needs to be considered to be used as alternative energy, replacing and reducing the role of fuel oil for energy consumption in Indonesia. The testing of this tool aims to produce hydrogen gas which can be used as an alternative fuel and provide an innovation in the form of control to obtain data from the hydrogen gas production. The method of obtaining hydrogen gas by electrolysis is applied to the reactor using Stainlees Steel as the cathode-anode and Na2CO3. as a catalyst solution in the experimental process. The voltage source used in the reactor is 675 volts DC with a current of 10 A and the Arduino control system is used as an automatic control system. Furthermore, after the production process, the hydrogen gas produced from the electrolysis process is inserted into the hydrogen gas storage tube through the manifold hose. The results of the implementation carried out in producing hydrogen gas using the Arduino control system during the 2-minute experiment obtained a gas volume of 30.22 KPa, then the results of data analysis were carried out after production was running for 1 hour, which obtained 5.06 liters of hydrogen gas.

Abstrak Krisis energi yang melanda dunia berdampak pada tingginya harga minyak mentah dunia, sehingga berpengaruh langsung terhadap kegiatan perekonomian. Kekayaan sumber daya energi, khususnya sumber energi baru dan terbarukan yang kita miliki, perlu dipikirkan untuk dimanfaatkan sebagai energi alternatif, menggantikan dan mengurangi peran bahan bakar minyak untuk konsumsi energi di Indonesia. Adapun pengujian alat ini bertujuan untuk menghasilkan gas hidrogen yang dapat digunakan sebagai bahan bakar alternatif dan memberikan suatu inovasi berupa kontrol untuk mendapatkan data-data dari hasil produksi gas hidrogen tersebut. Metode pemerolehan gas hidrogen dengan proses elektrolisis yang diterapkan pada reaktor dengan penggunaan Stainlees Steel sebagai katoda-anoda dan Na2CO3.sebagai larutan katalis pada proses percobaan. Sumber tegangan yang digunakan pada reaktor adalah 675 Volt DC dengan arus 10 A serta penggunaan sistem kontrol arduino sebagai sistem kendali otomatis. Selanjutnya setelah proses produksi berlangsung gas hidrogen yang dihasilkan dari proses elektrolisis dimasukkan ke dalam tabung penampung gas hidrogen melalui selang manifold. Adapun hasil dari pelaksanaan yang dilakukan dalam menghasilkan gas hidrogen menggunakan sistem kontrol arduino selama percobaan 2 menit diperoleh volume gas sebesar 30.22 KPa, kemudian hasil analisa data dilakukan setelah produksi berjalan selama 1 jam akan diperoleh gas hidrogen sebesar 5.06 liter.

The Advantages of electronics equipment requires the increased efficiency and technology to reduce the use of electrical energy. The electrical equipment in residential energy consumption is the dominant burden on electricity supply service. Audio Amplifier is a widely used household appliance in general based on the linear transformer. A Linear transformer has much deficiency such as dimensions of equipment and the use of technology control systems which less of good and large voltage drop. Because of that, the design of Switch Mode Power Supply (SMPS) model would be a replacement linear transformer. In this research, we will compare the performance of Linear Trafo with SMPS specification +/- 35VDC - 350W. By making modifications to SMPS on the transformer windings which could be seen as the significant comparison to the use of equipment.
The increasing use of electrical energy in society in 2020 is closely related to the pandemic problem that is occurring. Increased household activity causes a surge in energy in the household sector. This increase in energy consumption needs to be balanced by providing exposure to the utilization of existing electrical equipment in households. The lighting system give an important role in energy consumption in the household sector. The dedication carried out is by providing knowledge on the use of the lighting system, the rules in PUIL 2000 and the calculation of the Basic Electricity Tariff (TDL) in 2020. Submission of this will certainly increase public understanding of energy savings so that it can contribute to overcoming the problem of electricity devisit occur.
Berkembang dan bervariasi, untuk memenuhi kebutuhan tersebut industri membutuhkan suatu alat yangdapat mengontrol dan mengendalikan proses permesinan secara otomatis sehingga mempermudah danmenghemat tenaga manusia. sebagian besar industri menerapkan sistem control menggunakanMikrokontroller sebagai alat kontrol kerja produksi, seperti alat conveyor untuk pemilahan buah berdasarkan ukuran yang dikendalikan oleh Mikrokontroller ATMEGA16, dengan menggunakan sensorultrasonic sebagai pengukur ukuran objek dan kombinasi photodioda dan motor servo dapat mendeteksikeberadaan objek lalu dapat mensortirnya. Perancangan conveyor pada penelitian ini menggunakan jenis Belt Conveyor dengan komponen utama roller dari bahan pvc, kerangka dari bahan akrelit, sabuk (Belt) dari bahan lakban, motor dc sebagai penggerak sabuk juga roda gigi (pulley) dan Terdapat 3 buah motor servo yang difungsikan untuk memilah buah jeruk berdasarkan ukuran kecil, sedang, dan besar. Perancangan conveyor yang dilengkapi pemilah benda ini dapat dibuat dengan menggunakan ATMEGA 16 sebagai kontrolernya. Sensor ultrasonic HC-SR04 berfungsi dengan baik untuk mengukur ukuran objek, dan kombinasi photodioda dan motor servo dapat mendeteksi keberadaan objek lalu dapat memilahnya. Kemudian data dicacah oleh mikrokontroller dan ditampilkan pada layar LCD.
