Rancang Bangun Sistem Telemetri Multi-channel Untuk Monitoring Suhu Dan Ph Air Menggunakan Jaringan Wifi

Water quality monitoring is very important to know condition of the water in a sector location. The water quality monitoring can anticipate a decrease of water quality by knowing water condition in real-time, in that way can be determined what factors that causes a decrease of water quality. The method used for water quality monitoring system in this paper is telemetry system (remote measurement) with the wifi network. Telemetry system choosed because its more efisien than the other, measurement can be remotely and in real-time. The test of water quality is bad or good can be known from the elements of test parameters. Parameters sample tested of this research are temperature and pH of the water. To respon physical symptom of changes in amount of water temperature used temperature sensor RTD (resistance temperature detector), and a pH sensor to respon condition of pH of the water. Both of the sensor\u27s reading are converted from analog to digital (ADC) using microcontroller ATmega8535. Microcontroller ATmega8535 has USART feature (Universal Synchronous and Asynchronous Serial Receiver and Transmitter) as a serial communication mode. Serial communication technique in a multi-channel is done by using the RS-485 protocol as a communication link beetwen one unit to another until can connect 32 and using the RS-232 protocol to connect serial communication data to personal computer (PC). The data that has been obtained is sent to the monitoring station by a telemetry technique using the wifi network. Results of the data acquisition system RTD temperature sensor against a standard thermometer has a linear correlation coefficient R = 0.998. And the results of the data acquisition pH sensor against a standard pH meter has a linear correlation coefficient of R = 0.994. Results of the comparison between the data sent and received data has errors = 0 so that it can be ascertained no data is lost or gained

Learning Models in Educational Game Interactions: A Review

Educational games have now been used as innovative media and teaching strategies to achieve more effective learning and have an impact that tends to be very good in the learning process. However, it is important to know and systematically prove that the application of the learning model in the interaction of educational games is indeed feasible to be adopted and has an effect. This paper aims to present empirical evidence of the current situation regarding the application of learning models in the flow of educational game interactions. The method used is a systematic literature review by adopting three main stages, namely: 1) Planning; 2) Implementation; 3) Reporting. Then recommend the ten steps in the systematic literature review process along with the selection process through the test-retest approach. The initial search obtained 1,405,310 papers, then go through the selection stage. The selection process took place at stage B1 with the number of papers that successfully passed 198, at the B2 selection stage there were 102 papers, and we focus 75 papers that have passed a fairly rigorous screening and selection process on the quality assessment process for primary studies, used to answer research objectives and questions. We can confirm and conclude that 75 papers have applied the learning model in educational game interactions. The dominating domain is Education, the type of game that dominates is Educational Game, for the most dominating subjects are Programming, Student Learning Motivation as the most dominating impact, Experimental Design as a trial technique, the most widely used evaluation instruments are Questionnaires and Tests, a population that dominates between 79-2,645 people, and 8 papers to support learning in vocational education

Intelligent Sensing Using Metal Oxide Semiconductor Based-on Support Vector Machine for Odor Classification

Classifying odor in real experiment presents some challenges, especially the uncertainty of the odor concentration and dispersion that can lead to a difficulty in obtaining an accurate datasets. In this study, to enhance the accuracy, datasets arrangement based on MOS sensors parameters using SVM approach for odor classification is proposed. The sensors are tested to determine the sensors' time response, sensors' peak duration, sensors' sensitivity, and sensors' stability when applied to the various sources at different range. Three sources were used in experimental test, namely: ethanol, methanol, and acetone. The gas sensors characteristics are analyzed in open sampling method to see the sensors' performance in real situation. These performances are considered as the base of choosing the position in collecting the datasets. The sensors in dynamic experiment have average of precision of 93.8-97.0%, the accuracy 93.3-96.7%, and the recall 93.3-96.7%. This values indicates that the collected datasets can support the SVM in improving the intelligent sensing when conducting odor classification work
