Abstract

Student motivation at class takes major role on achieving courses’ learning outcomes. Multimedia based content, game-based quiz, or self-assessment can maintain student interest to follow the learning process. Apart from the individual solution, working in group is one way to improve student motivation, however without proper arrangement, putting students in groups can degrade the competitive atmosphere of class, as less-smart students hang up to the more-smart students. Another alternative is implementing collaborative learning such as peer assessment that allows students to grade their fellows. However, objectivity between students must be concerned as students tend to give high-grade for their fellows. Combining group mode and peer assessment, this work proposed group peer assessment to improve student motivation on e-learning. Proposed method started by teacher open a group assignment on e-learning. Students then work on group to create solution. After the solutions are submitted, the extra-group peer assessment begins, where each group examines another group work. To maintain the objectivity of the peer assessment, final grade of each group obtained by combining grade from another group and grade from teacher. In the meantime, cooperation atmosphere in each group is maintained by intra-group peer assessment, where each member asses all his/her teammates in terms of intra-personal and inter-personal skills.

Abstract

Technological developments in the field of electronics to date have made the humanmindset advanced in the application of electronic equipment. One example of its development isremote control of electrical equipment. Many people use these developments as a means offacilitating life activities in solving problems that occur. The use of the internet in life can beused as an example in the use of technological developments. The internet is one of thecommunication media that has many benefits in increasing effectiveness, work efficiency, andmonitoring. The internet can be used as a transmission medium for control and monitoringsystems. With the internet, one can control electrical equipment and monitor the condition of thehouse. The concept originated from the Internet of Things or IoT. IoT is a concept where alltools and services in the system are connected to each other using internet media. Based onthese problems, a smart home system was created that functions as control of electricalequipment, smoke detection, monitoring of temperature and humidity in the room. Themonitoring and control system is integrated with Android applications and based on the Internetof Things.

Abstract

The Indonesian Wheeled Football Robot Contest (KRSBI Beroda) is one of the divisions of the Indonesian Robot Contest (KRI). At KRSBI Beroda robots are expected to be able to move automatically by using the Base Station as a communication center between robots in the same team. Base Station has a function to forward orders from the referee or RefBox (Referee Box) to the robot. This study aims to add features to the Base Station by displaying the position of two robots in the field in animation using the multi-thread method to facilitate strategy formulation. The result is that the Base Station that is made can display the position of two robots in the field without any errors.

Abstract

These days technology has developed rapidly, almost covering all aspects in humas life for example is automation system. The automation system works without human intervension and complete all works independently. Existing technology can already be connected to each other via the internet network so that it can transmit or receive data automatically. The Internet of Things (IoT) can support automated systems by providing real-time information so that users can monitor the performance of these automated systems. This research was to develop rabbit cage by utilizing microcontroller as monitoring system. The system utilizing Internet of Things (IoT) as monitoring medium between users and devices to help users monitor their rabbit cage remotely. The design installed several sensors such as ultrasonic, temperature, load cell sensors, DS18B20 and water level sensors. This research used Arduino Mega 2560 as main microcontroller and NodeMCU ESP8266 as communication device between the tools and database. The tools use android application on user smartphone that fuctions real time monitoring for the cage. Based on the results of this research by using Arduino Mega as microcontroller board to controlling and monitoring rabbit’s cage has succesfully in monitoring the cage via internet through the NodeMCU ESP8266 intermediary according to the design.

Abstract

The existence of Public Electric Vehicle Charging Stations (SPKLU) is increasing alongside the rise in electric vehicle usage in a certain area. EVCS is equipped with devices that directly interact with electric vehicles (EVs) during charging; this device is called Electric Vehicle Supply Equipment (EVSE). Both EVSE and EV require protocols to communicate with each other aimed at exchanging information such as readiness for charging between EVSE and EV. The communication protocol used in this research is the SAE J1772 protocol. This study focuses on designing a hardware prototype of EVSE based on the principles of the J1772 AC Type 1 connector as the transmission medium to electric vehicles (EVs). The design of EVSE communication simulation uses the Falstad Circuit Simulator platform, and the PCB layout design uses the EasyEDA platform. The hardware prototype of EVSE is controlled using a Raspberry Pi 3B mini PC as the core management, then integrated with the initial terminal block, power supply block, PZEM-004T sensor module, J1772 communication block, 2-channel solid-state relay (SSR) module, and J1772 terminal.
