This online complaint or information submission application is a web-based application which is useful to assist employees obtain information online. Currently, the complaint and information submission are still using the old method by asking the question through the relevant employees manually. This way is inefficient in terms of time due to some employees are not always available in place. Therefore, with the development of technology, it encourages the researcher to design web-based application system which is useful for assisting employees to submit complaint and information. This design process using a Navigation Structure, Unified Modeling Language and Forward Chaining method as a data processor. Out of the two technology that have been tested (laptop and smartphone), this application works well on laptop, while on smartphone, the button layout does not appear, as well the display it does not respond horizontally or vertically. This application will be assist the pharmaceutical company employees to submit information and complaints anytime and anywhere easier.
The Internet of Things (IoT) aims to expand the benefits of being connected to the Internet network continuously. It functions as a control system that has been widely applied in various fields because in certain case people are not allowed in certain rooms for security reasons. The research aimed to create a temperature and humidity monitoring system using as many fan controls as expected by utilizing IoT. The model used input in the form of temperature and humidity sensors. The output was a motor driver that drove a fan and used a microcontroller as the main processor. IoT-based systems consisted of hardware and software. Hardware included NodeMCU ESP8266 V3, DHT22 sensor, L298N motor driver module, fan, and computer. Meanwhile, the microcontroller software was made using Arduino IDE. From the test results, the system model works well. Fan control is set manually based on desired room temperature and humidity monitoring based on IoT. A mobile phone can also monitor temperature and humidity and control fans. The DHT22 sensor can read temperature and humidity every two seconds so that the resulting data is stable to display. Then, the L298N motor driver can adjust the fan speed with Pulse Width Modulation (PWM) using analog data ranging from 1 to 1.024.
Saat ini, banyak sekali permainan-permainan dengan grak yang sangat canggih dan telah menjadi permainan sehari-hari bagi masyarakat. Namun sayangnya, permainan-permainan berkualitas tinggi masih dirasa kurang mendidik dan merusak perkembangan jiwa bagi anakanak. Berdasarkan pengamatan tersebut maka dirancanglah sebuah aplikasi permainan sederhana. Aplikasi permainan sederhana yang dirancang dalam penelitian ini adalah aplikasi permainan OXTOE, sebuah perangkat lunak permainan tradisional Tic-Tac-Toe yang sederhana namun memiliki banyak sekali manfaat bagi pemainnya. Aplikasi Permainan OXTOE ini ditujukan bagi pengguna segala usia dan segala gender. Aplikasi Permainan OXTOE dibuat bertujuan untuk memperkenalkan dan mempopulerkan kembali permainan tradisional Tic-Tac-Toe yang pernah berkembang kepada masyarakat dan mendigitalisasikan permainan tradisional yang mengasah otak (tic tac toe) sehingga dapat dikenal dengan baik oleh anakanak di era digital. Aplikasi program Permainan OXTOE ini berbasis Visual Studio 2010 dengan bahasa pemrograman Visual Basic.NET.
