Abstract

This research is motivated by the many cases of theft of assets that occur. Property theft cases continue to occur even though the authorities have been to anticipate criminal acts of theft through existing laws and regulations. Therefore an alternative security system is needed that can reduce cases of theft of property. This research is one of the alternatives for anticipating theft cases. The purpose of this research is making and test a prototype of home door security system based on solenoid door lock, magnetic sensor, NodeMCU ESP8266 microcontroller and Blynk applications. Making the system is divided into two, namely making hardware and software. Making hardware system has three stages. The first stages is to make home mokup, the second stage is connect the sensor to the components use and the last stage is pair the system that has been created into the home mokup. Making software system has two stages. The first stages is make widget in Blynk application and the second stages is make sketch program use Arduino Software. System testing has two variations for finding the percentage of success a system. The two variations are keystrokes test and breaking door test. The result is prototype of home door security system based solenoid door lock, magnetic sensor, NodeMCU ESP8266 microcontroller and the Blynk application have been built and tested for success. The results of testing the success of the door security system obtained a success percentage of 100% for door 1, 2 and 3.

Abstract

Calcium wave propagation pattern modeling has been successfully carried out in astrocyte network using Brian2 simulator. The astrocyte model is defined by the Li-Rinzel equation which involves the IP3Rs (q) activation fraction. IP3Rs activation fraction parameter (q) affects the value of calcium concentration in astrocytes. The connection between astrocyte is in the form of Gap-Junction Channels (GJCs). The variation in this modeling is the number of astrocyte cells stimulated by external currents in the astrocyte network being modeled. The modeling results show that the IP3Rs (q) activation fraction can affect the propagation of calcium waves in astrocytes through activation of IP3 receptors

Abstract

The modeling of neuron-astrocyte interactions in neural networks has been successfully carried out using the Brian2 simulator. The neuron model used is Integrate and Fire, while the astrocyte network model is defined by the Li-Rinzel equation which involves the IP3Rs (q) activation fraction which affects the value of calcium concentration in astrocytes. Interaction modeling between neuron networks and astrocytes involves four types of connections, namely connections between neurons connected by synapses, connections between astrocytes in the form of gap-junction channels (GJCs), synaptic connections to astrocytes and astrocyte connections to synapses. The synaptic connection to the astrocytes is made to trigger the activation of the astrocytes by releasing the neurotransmitter. The astrocyte connection to the synapses is established as a route for the production of the gliotransmitter. The modeling results show that the information transfer mechanism carried out by neurons is in the form of electric current wave propagation, while the information transfer carried out by astrocytes is in the form of calcium wave propagation.

Abstract

Electronic nose (e-Nose) has successfully classified the aroma of horse hide and pigskin. The sensor used by e-Nose consists of eight Taguchi Gas Sensor (TGS) sensors. This study uses a baseline reduction and feature extraction method with an average maximum value. The classification results between the two skins are shown by a graph plot. There is one TGS which shows no difference between the smell of horse skin and pork rind. The other TGS responds and shows the difference between the two skin scents.

Abstract

Research on installation and evaluation of early warning systems based on the HC-SR04 ultrasonic sensor and the Internet of Things (IoT) has been successfully carried out. This study aimed to install and evaluate a flood early warning system based on the ultrasonic sensor HC-SR04 and IoT at a flood monitoring post, Boyong River Yogyakarta. Installation of a flood early warning system based on the HC-SR04 and IoT ultrasonic sensor was carried out by preparing tools and materials, connecting WiFi, and installing the system. Evaluation accuracy of the system was carried out by varying the distance between the sensor and the water surface, namely 5 cm - 200 cm with 5 cm intervals, while testing of precision and success were done by 10 times repeating for each distance variation. The results showed that flood early warning system based on ultrasonic sensor HC-SR04 and IoT has been successfully installed at the flood monitoring post, Boyong River Yogyakarta. In addition, the flood early warning system based on ultrasonic sensor HC-SR04 and IoT was successfully evaluated with an accuracy value 99.95%, repeatability precision 98.75%, reproducibility 99.27%, and success 89.50%.
