Abstract

Smart Home is a residence or dwelling where electrical appliances are connected to a communication network for control, monitoring, or remote access. One of the technologies used in creating a smart home is the Internet of Things (IoT). In this research, a prototype of a smart home was designed using the DHT11 Sensor and RFID (Radio Frequency Identification) Sensor. The controlled appliances include lights, fans, and a door lock. In the design of this IoT-based smart home, the results showed that the Internet of Things system functions optimally on the controlled hardware. The switching relay works well, where when the status in the application is ON, the lights will turn on, while when the status is OFF, the lights will turn off. In the automation of the DHT11 Sensor, when the room temperature exceeds 30°C, the fan will turn on, whereas if the room temperature is below 30°C, the fan will turn off. And in the automation of the RFID-RC522 Sensor, when a registered tag card is placed on the RFID reader, the door lock will open, but if an unregistered tag card is placed on the RFID reader, the door lock will remain locked.

Abstract

A line follower robot is a robot that works along a line. This robot is a very simple type of robot, so it is often used as training material for students who are new to robots. One of the indicators for assessing the performance of a line follower robot is the travel time achieved by the line follower robot in covering various trajectories correctly. The average speed of the robot at 90% and 75% PWM settings is almost the same with a value of around 41 cm/second, while at 50% PWM settings it is much reduced to 35.63 cm/second. At the 90% PWM setting, it can be seen that the path length ratio is 4.32: 2.06: 1, while the travel time ratio is 4.44: 2.66: 1. At the 75% PWM setting, it can be seen that the path length ratio is 4.32: 2.06 : 1. while the travel time ratio is 4.38 : 2.41 : 1. At 50% PWM setting, it can be seen that the path length ratio is 4.32 : 2.06 : 1. while the travel time ratio is 4.09 : 2.09 : 1

Abstract

ABSTRAK Penelitian ini membahas perancangan dan pengaplikasian implementasi teknik pendinginan pada prototipe data center. Seiring perkembangan teknologi maka kebutuhan atas ketersediaan infrastruktur yang memadai sangatlah penting. Data center merupakan infrastruktur yang penting dalam perkembangan teknologi. 30% dari penggunaan listrik keseluruhan pada data center digunakan untuk pendinginan. Oleh karena itu penelitian ini membahas teknik pendinginan mana yang tepat untuk di gunakan pada data center agar mendapatkan efesiensi dan peformansi maksimal. Prototipe dirancang menggunakan Arduino Mega sebagai mikrokontroler, LM35 sebagai sensor suhu, lampu bohlam sebagai sumber panas, dan kipas berukuran 8 dan 2,5cm sebagai sistem pendingin buatan. Dari hasil penelitian yang dilakukan diketahui bahwa cold aisle containtment system lebih baik dalam hal karakteristik suhu. Sedangkan dalam hal karakteristik ketahanan suhu sistem tanpa containtment lebih baik. Berdasarkan hasil penelitian diketahui bahwa untuk data center tingkat 1 dan 2 tidak direkomendasikan menggunakan cold aisle containtment system karena dapat mencapai suhu panas lebih cepat ketika terjadi pemadaman pendingin, sedangkan untuk data center tingkat 3 dan 4 lebih direkomendasikan menggunakan cold aisle containtment system karena menghasilkan efesiensi pendinginan lebih baik di banding sistem tanpa containtment.

Abstract

Speech recognition technology makes human contact with the computer more accessible. There are two phases in the speaker recognition process: capturing or extracting voice features and identifying the speaker's voice pattern based on the voice characteristics of each speaker. Speakers consist of men and women. Their voices are recorded and stored in a computer database. Mel Frequency Cepstrum Coefficients (MFCC) are used at the voice extraction stage with a characteristic coefficient of 13. MFCC is based on variations in the response of the human ear's critical range to frequencies (linear and logarithmic). The sound frame is converted to Mel frequency and processed with several triangular filters to get the cepstrum coefficient. Meanwhile, at the speech pattern recognition stage, the speaker uses an artificial neural network (ANN) Madaline model (many Adaline/ which is the plural form of Adaline) to compare the test sound characteristics. The training voice's features have been inputted as training data. The Madaline Neural Network training is BFGS Quasi-Newton Backpropagation with a goal parameter of 0,0001. The results obtained from the study prove that the Madaline model of artificial neural networks is not recommended for identification research. The results showed that the database's speech recognition rate reached 61% for ten tests. The test outside the database was rejected by only 14%, and 84% refused testing outside the database with different words from the training data. The results of this model can be used as a reference for creating an Android-based real-time system.

The movement of the sun from east to west that periodicity in every day is a problem at  the  optimization generation of electricity at  Solar Power Plant   if using solar panel that motionless. This is because the solar cell panel can not catch the maximum sun exposure. To solve the above problem then designed a solar cell panel  tracker  capable of follo-wing the movements of the sun. Then conducted a test to see the performance of solar cell pa-nel  tracker  and compare it with the performance of solar cell panel was motionless. The testing doing along 6 days, with way to irradiate the panel of solar cells  tracker  and panels of solar cell motionless with sun exposure  along a  full day. Then the electric current generated each panel were recorded. The comparison of current then generating comparison of electric power delivery. The result show that the solar cell panel  tracker  produce the average current is 2.19 A whereas solar-cell panel still 1.97 A.  This result   indicate that average power for solar cell panel  tracker  39.41 W while for solar cell panel that motionless is  35.46 W. These results indicate that the performance of solar cell panel  tracker  better than  solar cell panel motionless.

Abstract

Dalam proses pasteurisasi jamur tiram, pengontrolan suhu media tanam jamur tiram biasanya masih dilakukan secara konvensional. Cara yang biasa dilakukan ialah dengan  memperbesar atau memperkecil api yang digunakan dalam proses pemanasan atau pengukusan. Proses pengontrolan secara konvensional dirasakan tidak efektif karena membutuhkan perhatian serius agar suhu ruangan pasteurisasi tetap stabil sekitar 70ºC . Faktor kelupaan manusia, sebagai operator pengontrolnya  disamping menyebabkan proses pasteurisasi tidak berhasil juga akan menyebabkan pemborosan penggunaan bahan-bakar. Untuk mengantisipasi hal tersebut diatas, maka pada penelitian ini mencoba untuk merancang suatu alat yang dapat mengontrol suhu pasteurisasi secara elektronik, yang kemudian  dapat  mengontrol aliran bahan bakar yang digunakan sesuai kebutuhan. Prinsip pengontrolan didasarkan pada logika fuzzy yang diaplikasikan pada  Mikrokontroler AT89S52. Dari hasil pengujian yang dilakukan, suhu pasteurisasi yang diinginkan  dapat tercapai dalam waktu sekitar 19 menit dan peralatan yang dibuat dapat menjaga suhu ruangan stabil sekitar 70ºC selama proses pasteurisasi berlangsung.

Abstract

The issue of waste management has become increasingly important alongside the growth of population and public consumption. Improper disposal of waste types leads to environmental and health problems. To address this, it is necessary to develop technology that can aid in the efficient sorting of waste. This study aims to: first, design and build a waste sorter for organic, metal, and non-metal waste using the ESP32 microcontroller; and second, understand the operating system of the organic, metal, and non-metal waste sorting device. This research utilizes a design and implementation method for the waste sorter based on the ESP32 microcontroller. The device is equipped with capacitive and inductive proximity sensors to detect waste types, as well as a servo motor to direct waste into the appropriate collection bins. The results of this study indicate that: first, the designed waste sorter can sort waste into three categories: organic, metal, and non-metal. Second, the capacitive and inductive proximity sensors can effectively detect waste types at a range of 2-6 cm. Third, the servo motor can drive the sorting mechanism to direct waste to the appropriate collection bins. Fourth, this waste sorter can help improve efficiency and accuracy in waste management.
