Abstract

Saat ini harga bahan bakar seperti batu bara dan minyak bumi semakin mahal, salah satu penyebabnya ialah melemahnya nilai rupiah terhadap mata uang asing. Tingginya biaya bahan bakar yang harus ditanggung oleh pembangkit termal, telah mendorong peneliti untuk membuat optimasi penjadwalan pembangkit termal. Penelitian ini bertujuan memperoleh penjadwalan dan pembagian beban pembangkit tenaga listrik, guna mendapatkan biaya bahan bakar yang minimum, dengan tetap memperhatikan batasan equality dan inequality. Saat ini perkembangan teknologi soft computing semakin berkembang, terlihat dari banyaknya para peneliti menggunakan teknologi tersebut. Soft computing banyak digunakan karena kemampuannya dalam hal meniru akal manusia serta bersifat adaptif. Komponen utama soft computing dengan mengintergrasi sistem fuzzy dan jaringan syaraf tiruan. Metode hybrid neuro-fuzzy diterapkan pada pembangkit termal sistem interkoneksi 500 kV Jawa-Bali. Hasil optimasi hybrid neuro-fuzzy tersebut dibandingkan dengan kondisi riil di lapangan. Berdasarkan hasil optimasi didapat bahwa metode hybrid neuro-fuzzy tersebut lebih ekonomis dibandingkan dengan kondisi riil sistem.

Abstract

ABSTRAKRobot bermanfaat untuk membantu manusia dalam mengerjakan pekerjaan yang berbahaya contohnya pemadam kebakaran. Oleh karena itu perlu dikembangkan robot cerdas pemadam api yang mampu mencari sumber api dan kemudian memadamkannya. Penelitian ini bertujuan membuat rancang bangun robot cerdas pemadam api menggunakan mikrokontroler ATmega128 sebagai pengendalinya. Proses pencarian sumber api dilakukan dengan cara memeriksa tiap ruangan apakah terdapat sumber api atau tidak. Pencarian titik api dilakukan dengan mendeteksi pancaran sinar ultraviolet yang dipancarkan api dengan menggunakan sensor UVTron flame detector. Untuk memadamkan api digunakan kipas yang digerakkan oleh motor DC. Robot bergerak secara otomatis menggunakan aplikasi dari motor DC. Robot menggunakan sensor PING ultrasonic range finder untuk memandu navigasi robot dalam pencarian ruangan, menghindari halangan, mendeteksi arah gerak dan untuk kembali ke posisi start robot. Hasil penelitian menunjukkan bahwa robot cerdas pemadam api dapat dibuat dengan menggunakan perangkat keras dan perangkat lunak yang dikontrol menggunakan mikrokontroler ATmega128. Dari pengujian yang telah dilakukan dapat disimpulkan bahwa robot cerdas pemadam api ini dapat memdeteksi api hingga jarak 5 meter dan dapat memadamkan api dalam waktu rata-rata 38.6 detik.

Abstract

Fish management systems have an important role in fish farming. One aspect of fish management is water quality which includes several things such as temperature, pH, oxygen levels and also feeding. So far, monitoring of water quality and feeding of fish has been done manually. This study aims to design a control-monitoring system for oxygen levels, pH, temperature and automatic feeding based on IoT. The reading data from the sensor and also the RTC will be forwarded by the microcontroller to the server to be displayed to the user. This system is automated with actuators in the form of aerators and motors, so that feeding and adding oxygen levels to the pond will be automatically carried out by the microcontroller. The results of this study indicate the system can work, temperature data, oxygen levels, pH can be monitored through the server and feeding can also be done.

Abstract

During the pandemic situation, laboratories with a limited number of equipment cannot be used to their full capacity to avoid over crowded. Thus, innovation is needed in the design and arrangement of laboratories so that they can be accessed remotely with flexible schedule. However, when the community service team studied cases of teaching and learning practices during the pandemic, problems were found, among others, the imbalance between the number of tools and users, as well as limited practical opportunities in online-based learning. Therefore, in this community service a remote laboratory which could be accessed from where the users were as long as they connected to the internet was designed to provide solution to the problems. The designed remote laboratory utilized the Internet of Things (IoT) to help students do practicum on the topic Microspcope by using a remote desktop employing TeamViewer technique as a tool to access the lab computers with the users’ device. As expected, it is proven that remote laboratory can be used to overcome the imbalance between the number of laboratory equipment and laboratory users, and to avoid dangerous crowds during the pandemic as it can be accessed from where the users are located as long as they are connected to the internet.

Abstract

Nowadays, water faucets play an important role in controlling water flow. Besides that, faucets are generally moved manually by every human activity by turning or moving the faucet up or down. This manual faucet system has weaknesses, namely water wastage and easily damaged faucets. The use of automatic faucets in public facilities can minimize waste their use because generally people often forget to close the faucet again. Besides, using Arduino-based automatic water faucets can reduce the transmission of Covid 19 for the community, especially during the current pandemic. This activity aims to design Arduino-based automatic water faucets at public facilities to reduce the spread and transmission of COVID-19, especially in the Girimekar Village area, Bandung Regency. The target of this activity is youth and cadets in the area. The implementation of the Arduino-Based Automatic Water Faucet design in training resulted in a prototype unit of Arduino-based automatic water faucet using the ultrasonic sensor HC-SR04 as detection and use of an electric solenoid valve as a form of direct water control.

Abstract

One of the user interface problems in an internet of things (IoT) system is influenced by monitoring which is easy to access, flexible and efficient in its use, has been discussed a lot but the problem is still unresolved, one solution to this problem is by presenting the Adafruit mqtt, which by using the mqtt Adafruit user interface for monitoring on an internet of things system can facilitate control and remote control. In this case the use of Adafruit mqtt is used to monitor electrical loads and improve power factor. This research presents an internet of things system that is capable of monitoring electrical load and improving power factor that already uses the Adafruit mqtt as its user interface. The method used is through the Analysis, Design, Development, Implementation, Evaluation (ADDIE) approach. The results showed that this system is feasible to use because based on the experimental results this system is able to work well and provide convenience for users and can monitor in real time current, voltage, energy, frequency, power factor, real power, apparent power, and reactive power. only by using smartphones, laptops, tablets, or computers. It is hoped that in the future this research will be able to continue to be developed so that the use of electrical energy in industry can be much more effective and efficient.

Abstract

The development of an urban area should be followed by the arrangement of adequate infrastructure. One of the important needs in an urban area is transportation. An increase in the number of means of transport often creates congestion, especially at intersections. The timing of cycles that do not lead tothe number of vehicles lining up but only based on a balanced division of time is one of the causes of congestion. Based on this background, a system of setting the flame cycle of the lamp u basedon the length of the queue is needed. This study aims to implement the Sydney Coordinat Adaptive Traffic System (SCATS) application as a solution to overcome traffic congestion in DKI Jakarta. The method used is to use quantitative methods with the 1997 Indonesian Road Capacity Manual (MKJI) approach. The results obtained include, the SCATS application can adaptively adjust the cycle time of sensor-based traffic lights. Traffictraffic settings can be manually controlled by the operator remotely using an internet communication network and can be conditioned with special cases or emergencies. Based on the results of the study, the SCATS application is expected to be implemented in all major cities in Indonesia.
