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— In the development of technology, the application of automated systems began to bloom applied in various fields. The automatic system is able to provide convenience in its application, both in terms of time and energy efficiency. In general, an automatic system can be interpreted as a system that is capable of carrying out a job without human intervention. researchers designed a device that is able to work automatically to water the plants based on the soil conditions of the plants. an automated system designed by researchers using the Arduino Mega 2560 microcontroller as the main control and soil moisture sensor to detect soil moisture levels. The process of watering plants occurs based on the level of humidity that has been detected by a soil moisture sensor. Result of the tests on this research, the watering process is carried out when the soil moisture level is less than 20%. Meanwhile, when the soil moisture level is more than 20%, the watering process will stop.

The aquarium monitoring system in the maintenance of ornamental fish is fundamental to maintaining the survival of the aquatic biota in it. In this study, a prototype of a water condition monitoring system such as turbidity and water temperature in freshwater ornamental fish aquariums was designed and integrated with IoT technology so that it could make it easier for ornamental fish owners to maintain freshwater ornamental fish remotely. In the prototype tool, there is a turbidity sensor SEN0189, a temperature sensor DS18B20, and an HC-SR04 sensor, which function to measure changes that occur in each parameter. Each sensor data will be processed by the Arduino Uno microcontroller, which is then sent to the NodeMCU ESP8266 (Wi-Fi module) via serial communication so that sensor data readings can be displayed on the Blynk application. As a result of the tests, the system can monitor the turbidity of the water and drain the water if the turbidity reaches >= 25 NTU and refill the aquarium with clean water. In addition, the system can also monitor and control the water temperature in the aquarium. The aquarium water temperature level is maintained in the range of 24°C – 28°C.

Aquaponics is one of the methods of farming in urban areas that produces fish and vegetables at the same time. One aspect that can improve the quality of aquaponics products such as catfish and water spinach in a short period of time is the addition of Internet of Things (IoT) systems. This technology allows farmers to automate work and monitor aquaponics media remotely. Before applying this technology, it is necessary to analyze to what extent each aquaponics system improves the quality of fish and vegetables. The purpose of this study is to compare the productivity of materials needed to grow catfish and water spinach in IoT-based aquaponics and conventional aquaponics. The parameters studied to support the results of the analysis are fish weight and vegetable weight after 14 days. The results show that the weight of fish and vegetables produced by IoT aquaponics is heavier than that produced by conventional aquaponics, which leads to a higher number of production units. It makes the IoT aquaponics productivity percentage value greater with a productivity difference of 112%, which indicates that the IoT aquaponics system manages the required materials more efficiently in a short period of time.
