Abstract

INTERACTION OF MOLTEN URANIUM WITH ELECTRICAL PENETRATING TUBE OF A BOILING WATER REACTOR DURING SEVERE ACCIDENT. Fukushima accident was the first severe accident of a BWR type which the core was melted leading to RPV failure at the bottom head. Regarding its complex structures of the bottom head, the scheme of failure is different from that of previous reactor severe accidents that ever happened (i.e. TMI-2 and Chernobyl accidents). There is a lot of penetration tubes through the bottom head leading to a complex interaction between corium and the structures. Eutectic reaction is possible to happen due to high temperature leading to a rapid failure of the RPV. Therefore, it is important to understand the phenomenon of interaction between corium and the structures. In this study, an interaction between molten uranium and structure of electrical tube, one of the penetration tubes, was analyzed by using MPS-LER method. Fluid dynamics of the MPS-LER simulation was validated by experiments of fluid flow by using water and oil.Calculation results of the fluid flow showed a good agreement with that of experiments.The MPS-LER was applied to calculate the penetration rate of molten uranium which flowed through the wall of the electrical tube at the bottom head of a BWR. The penetration rate was high due to eutectic reaction. The rate achieved 555.56 µm/s. Conservatively, it took less than 1 minute of time for the molten uranium to melt the tube wall with a thickness of 1.232 cm.

Abstract

Abstract: Maintaining health is very important for life especially in the current Covid-19 pandemic. One of the protocols imposed by the government for people who do in public spaces or open facilities is to check body temperature. In this study, arduino-based body temperature gauges were designed to have reminder alarms if the body temperature was above 37.30 and connected to a computer device via bluetooth. This body temperature gauge utilizes the DS18B20 sensor to measure temperature in celsius (0C). Body temperature data is also displayed on the 16x2 (cm) LCD found on the appliance. The test results of body temperature measuring instruments compared to thermo guns and have a deviation range of 1.16% - 2.02%. This body temperature gauge is expected to be installed in public places that need to conduct checks on the people who will be active in the room, the operator can stand at the control table so that it does not come into direct contact with the community.Abstrak: Menjaga kesehatan merupakan hal yang sangat penting bagi kehidupan terutama di masa pandemi Covid- 19 sekarang.

Abstract

In this pandemic era, doors in public places are one of the objects that can be an intermediary for the transmissionof the Covid-19 virus. That's why various kinds of developments in the field of technology are designed to provide an alternative in avoiding the transmission of the Covid-19 virus through doors in public places.The purpose of this study is to design an Arduino Uno-based automatic door simulator using Proteus software. The sensor used in this system is a PIR (Passive Infra Red) sensor. The way the system works is that when the PIR sensor detects someone's movement, the Data OUT Pin will be HIGH. Because this pin is connected to the Arduino, it will detect this HIGH Signal and detect that someone is approaching the door and will provide input to the DC motor, then the DC motor will move to the right or left to pull the door. From the simulation results, the delay between sensor readings and the movement of the DC motor is about 3 to 5 seconds.

Abstract

The HPGe detector is a device that should be cooled when used and can be operated at room temperature. For this reason, it is necessary to monitor the temperature and humidity in the HPGe detector storage area to produce optimal performance. This research was focused on designing a Smart Detector Environment System as a means of monitoring and automatic control of temperature and humidity in the HPGe detector storage. Temperature and humidity detection in the system was carried out by the DHT22 sensor connected to Arduino Uno and the motor driver module. Arduino uno gave the command "00000011" to detect the temperature in the chamber, and "00000101" to start the detection of humidity in the chamber, then the data generated by the DHT22 sensor would be displayed and processed by LabVIEW, which was used to move the fan to regulate the temperature and humidity in the system with the condition that the lamp on the chamber was left on (manual).  The results obtained were in the form of a design and automatic control of temperature and humidity monitoring and control in the HPGe detector storage whose temperature could be adjusted automatically according to the needs of the HPGe detector.

Abstract

Desa Sinarancang Kecamatan Mundu, Kabupaten Cirebon adalah salah satu desa penghasil pertanian terbaik di Kecamatan Mundu. Agriculture is becoming more productive today as a result of advances and new technologies such as sensors, devices, and information technology, which help generate a large amount of data penyiraman secara manual tersebut dirasa kurang efesien, dikarenakan membutuhkan banyak waktu, tenaga, finansial berupa uang, dan pemilik tanaman tidak bisa meninggalkan tanaman dalam kurun waktu yang lama. Oleh karena itu Sistem Irigasi Otomatis berbasis solar panel dibuat dan diimplementasikan. Pada alat ini digunakan RTC sebagai alat hitung waktu. RTC yang digunakan adalah jenis RTC DS 1307 compitable Arduino. Solar Panel digunakan sebagai catu daya pengganti PLN. Komponen sistem terdiri dari solar panel, control box, pompa, dan keran nozzle. Sistem sudah dilakukan pengujian dan tegangan untuk mengaktifkan pompa adalah sekitar 12 volt. Selang waktu untuk mengalirkan air pada keran nozzle saat pompa sudah aktif sekitar 6- 10 second. Sistem diimplementasikan dilahan kering dengan memanfaatkan sumber air disekitar lahan yang berasalal dari dataran yang lebih tinggi sehingga menjadi efektif untuk sistem penyiraman.

Abstract

BUMDes Rancang Jaya has several activities such as a cafe business unit, village water management business unit, agricultural product management business unit, handicraft and industrial business unit. On agricultural land, there are several obstacles, one of which is the lack of resources to manage agricultural land. Automating plantation irrigation activities can change the paradigm from a manual and static system to a more dynamic system that leads to increased water use efficiency and leads to higher production yields. Application of solar panel-based PETIS Technology applications to increase the efficiency and effectiveness of farmers in managing their crops. Especially in surface water utilization systems as irrigation water and in the consistency of giving water to plants because PETIS Technology uses the RTC system, which is automatic watering based on the desired time based on solar panels. The method used is advocacy. Starting with conducting surveys and observations to analyze partner problems, assembling and testing tools, installing tools, and providing community assistance. Solar panel-based PETIS technology can be utilized for an automatic watering system on agricultural land in Sinarancang Village, which has a high level of efficiency because the electricity comes from solar panels that are free of charge.

Abstract

Bermain layang-layang disekitar saluran transmisi dilarang, Hal itu tertuang dalam PerMen ESDM Nomor 02 Tahun 2019 tentang Ruang Bebas dan Jarak Bebas Minimum yang diijinkan pada Saluran Udara Jaringan Listrik. Untuk membersihkan layang-layang dengan cara konvensional mengharuskan tim pemeliharaan menggunakan tongkat pembersih sampah yang menyangkut di jaringan konduktor atau cara tertentu lainnya. Alat tersebut berguna untuk membakar sampah layang-layang yang tersangkut pada saluran transmisi yang pengendaliannya menggunakan dua Controller yaitu transmitter dan receiver dengan arduino sebagai pusat kontrol. Hasil dari penelitian ini menunjukan bahwa berdasarkan hasil pengujian, hingga jarak 20 meter drone flamethrower ini dapat mengirim dan menerima perintah sesuai dengan yang diinginkan dan berhasil membakar layang-layang pada jaringan sistem tenaga listrik dengan ketinggian 17 meter dan rata-rata waktu pembakaran untuk membakar 1 layang-layang selama 13 detik. Maka dapat disimpulkan bahwa perancangan alat drone flamethrower dapat berjalan dengan baik.
