Rancang Bangun Smart Home Berbasis Internet of Things
Full text linkTechnological developments continue to develop rapidly until the generation of the Internet of things (IoT). IoT is a collection of objects, in the form of physical devices (hardware / embedded systems) that can exchange information between operators or other devices connected to the system. One of the benefits that can be felt is a smart home or smart home, which is a term used to describe a modern residence, with remote control such as controlling electronic goods. This control is intended for savings in electricity use. By using the ESP32 which functions as a liaison between the device and the internet network so that electronic goods that are available from home can be controlled by using an application installed on the smartphone. Based on tests carried out for the same network with a distance of 20 meters the device is successfully controlled, namely turning on and off the electronic device with a response time of 5s for the fastest time and 40s for the longest time, then for different networks, the control can still be done. So that with this smart home application, electricity costs can be saved
Antarmuka Mikrokontroller IoT (ESP32) Dengan USB Host max3421e
Full text linkElectronic equipment made using old technology or electronic equipment in the entry-level category has not been supported by networking equipment, so for the data communication process, the microcontroller requires interfacing facilities that are in accordance with the electronic equipment used, such as a USB port. With the microcontroller that supports IoT, it allows electronic equipment to communicate over the network. An IoT microcontroller such as the ESP32 is equipped with a WiFi feature but is not equipped with a USB controller feature, while the USB Host max3421e supports the communication process using SPI, so that those two microcontrollers can be used to form an interface using the SPI bus. This interface can be applied to electronic equipment with old technology and entry level electronic equipment for wireless communication. For the needs of making an interface between the ESP32 and max3421e, a software was developed by analyzing the SPI features of the ESP32 and the USB protocol according to the USB device state diagram. The results obtained are the handshake process between systems developed with USB devices in the Low-Speed and Full-Speed categories such as printers, flashdisk, bluetooth mouse and external hard disk, and the device descriptor data of each device tested can be read properly
Pengembangan Game Molemash di Android Menggunakan Metode Rapid Application Development
Full text linkAs we know the game is one of the interesting applications found in gadgets. Many people who play games use their gadgets. The fans of this game come from various age segments. Although the majority is dominated by children and adolescents. Molemash is one of the popular games since time immemorial. This Molemash game is played by touching certain characters that appear on the gadget\u27s screen. The aim of developing this Molemash game is as a media to entertain children during the Covid-19 pandemic. Another goal is to introduce programming to today\u27s parents. The development method used is Rapid Application Development (RAD). One application that supports the RAD method is MIT App Inventor 2. MIT App Inventor 2 is one of the tools that supports the RAD method because it implements block programming so that it allows efficiency in terms of program lines that must be written. One block at MIT App Inventor 2 represents dozens or even hundreds of program lines. Users only need to arrange the blocks according to the desired logic flow. Therefore MIT App Inventor 2 is suitable for rapid software development. The result of developing this Molemash game is that children get alternative entertainment during the Covid-19 pandemic. Whereas in terms of parents get new knowledge related to game development on Android
Implementasi Algoritma Naive Bayes Untuk Memprediksi Tingkat Penyebaran Covid-19 Di Indonesia
Full text linkThe COVID-19 pandemic is the first and foremost health crisis in the world. Coronavirus is a collection of viruses from the subfamily Orthocronavirinae in the Coronaviridae family and the order of Nidovirales. This group of viruses that can cause disease in birds and mammals, including humans. In humans, coronaviruses cause generally mild respiratory infections, such as colds, although some forms of disease such as; SARS, MERS, and COVID-19 are more deadly. Anticipating and reducing the number of corona virus sufferers in Indonesia has been carried out in all regions. Among them by providing policies to limit activities out of the house, school activities laid off, work from home (work from home), even worship activities were laid off. This has become a government policy based on considerations that have been analyzed to the maximum, of course. Therefore this research was carried out as an anticipation step towards the Covid-19 pandemic by predicting the spread of Covid-19, especially in Indonesia. The research method applied in this research is problem analysis and literature study, collecting data and implementation. The application of the naive bayes method is expected to be able to predict the spread rate of COVID-19 in Indonesia. The results of the Naive Bayes method classification show that 16 data from 33 data were tested in Covid-19 cases per province with an accuracy of 48.4848%, where of the 33 data tested in the Covid-19 case per province tested there were 16 data that were successfully classified correctly
Aplikasi Penentuan Program Studi Calon Mahasiswa Menggunakan Simple Additive Weighting
Full text linkDecision support systems are part of computer-based information systems that are commonly used to support decision making in an organization or company. The decision support system is used as an alternative system that helps in making decisions to recommend the selection of study programs to prospective engineering faculty students. This decision support system uses the Simple Additive Weighting (SAW) method. The SAW method in this study uses five criteria, namely the value of mathematics, the value of English, the value of technology education, the value of cultural arts, and the income of parents. There are four alternatives used, namely Informatics, Civil Engineering, Architecture, and Urban and Regional Planning (PWK)

A mobile robot manipulator is a combination of a robot arm and a mobile robot so that this type of robot can combine the capabilities of the two robots. This paper discusses the design of a robot manipulator to be used in agriculture to replace farmers in the harvesting of agricultural products, such as tomatoes. This paper presents a mechanical, electrical design and uses the Fuzzy Logic Controller as artificial intelligence. The feasibility of the proposed method is demonstrated by simulation in Mobotsim
Analisa Dan Evaluasi Kinerja ATS Pada Pelanggan Premium Tegangan Menengah di PT. PLN UP3 Gresik
Full text linkIn an effort to meet customer needs on supplying electricity in the industrial era 5.0, it needs to have good services which keep growing up and be innovative. One of them is running a premium service which guarantees better quality of service than that of the regular. This research will discuss all of the obstacles that can disrupt the continuity of electricity supply to the customer with premium services, starting from the disruptions at the supply side until at the installation owned by the customer. From the analysis result, ATS (Automatic Transfer Switch) failed several times on working so that caused a black out at the customer side which it should be avoided. Therefore, it is necessary to make some adjustments on setting and wiring to some problems which may arise so that the potential disruption of the ATS or equipment failure can be suppressed. This research aims to minimize and even eliminate ATS performance failures due to system disturbances by implementing rewiring, adding a permissive interlocking system and adding a PLC with a time delay setting
