Abstract

The digestive system in humans is one of the materials taught in biology subjects. Submission of material about the digestive system in humans is still through conventional media such as blackboards and pictures contained in biology books. While this material about the digestive system is difficult to see directly because most of it occurs in the body. Augmented Reality is a technique that combines two-dimensional and three-dimensional virtual differences into a real sphere. Augmented Reality can be one of the effective teaching materials in elementary schools because of the rapidly advancing technology.

Abstract

Internet of Things (IoT) and smart city ecosystem, smart parking is an innovative solution that is relevant in developing a better future city. Along with the growth in the number of vehicles, parking spaces are available in public places such as development centers, airports, stations, and others whose capacity is increasingly limited. This research is to design an application and tool with the aim of arranging parking space reservations so that it is easy for drivers to get a spot. This design includes hardware and an Internet of Things connection with the designed application. This system connects IR Sensor to Arduino and NodeMCU wifi module. The NodeMCU chip consists of a SOC (system on a chip) with integrated TCP/IP protocol that allows Arduino to access the network. The cloud acts as a database to store all data related to parking areas and users who have access to the system. This component is placed in the parking area. The design results found that if there is a parked vehicle 2 LEDs will light up green, if obstructions or vehicles are not found, set to only 1 LED lit and a message is sent to the smartphone app informing them of unavailable parking. While the ultrasonic proximity sensor does not detect anything within 50 cm, on the app a white LED indicates that a parking space is available. A parking system that can provide parking location recommendations for checking sequences by a microcontroller program.

Abstract

In the context of fulfilling food, especially for agricultural and plantation commodities in East Kalimantan and fulfilling the Agriculture Polytechnic of Samarinda research strategic plan on Strengthening the Application of GIS and Remote Sensing for Land Management in the Agro-Ecosystem Zone, it is necessary to conduct studies related to determining suitable locations for smart farming in the location of the Agriculture Polytechnic of Samarinda. The closest technique in this study is to make a land model that is suitable for smart farming. The model was created by utilizing spatial data derived from remote sensing data, and also analyzed using GIS techniques. Several agricultural and plantation commodities have criteria as conditions for growth that must be met for each commodity. These parameters are conditions of humidity, temperature, and intensity of sunlight, where these data can be extracted from remote sensing data. By utilizing the NDVI, NDMI, and LST algorithms, as well as shadow analysis at the time of irradiation, it will be possible to model an area suitable for smart farming. By using spatial data from sentinel 2 and applying the NDMI, NDVI, and LST algorithms, it can be determined specifically which areas are suitable for several agricultural and plantation commodities. From the results of this study, it was found that several commodities could grow optimally in almost every location at the Agriculture Polytechnic of Samarinda, such as for the commodities of strawberry, rubber crop and robusta coffee. As for the commodities of Mustard Greens, Pepper, Cocoa, and Arabica Coffee, they are not suitable for planting in the Agriculture Polytechnic of Samarinda.

Abstract

Some plant species can move rapidly in response to various stimuli (e.g. touch). Some of these plant species are Mimosa Pudica L (Putri Ashamed) and the Venus Fly Trap plant. Previous electrophysiological studies have shown that electrical signals travel long distances and quickly through the Mimosa pudica plant (Putri Malu). Thigmotactic or seismonastic movements in Mimosa pudica, such as responses to touch, Mimosa pudica are electrically and mechanically analyzed using matlab software, i.e. if the voltage of the electric signal the output is 506mV-800mV or higher. Venus Fly Trap plant in response to mechanical stimulation. Electrical signaling and rapid closing of the Venus flytrap plant that electrically stimulated between the sheath and lobe closes the Venus flytrap leaf by activating a mechanically stimulated motor call from the trigger hair. Biologically closed electrical circuits operating over long distances in biological networks are electrically and mechanically analyzed using matlab software i.e. the generated electrical voltage signal is 512mV-555mV or higher. Activation of such a circuit can cause various physiological and biophysical responses. Here, we analyze the biologically open and closed electrical circuits of sensitive plants Venus’s fly trap and shy daughter by data acquisition with the measurements taken on this assay taking a time duration of approximately 9 s per test.

Abstract

This research aims to evaluate and implement the utilization of JSON Web Token (JWT) to verify the authenticity of letters in the letter system at the University of Muhammadiyah in East Kalimantan (UMKT). The previous method relied solely on QR code signatures, which were susceptible to copying and manipulation, thus posing vulnerabilities in the letter verification process. Therefore, this study used JWT tokens as a more secure and effective verification mechanism. The research involved creating JWT tokens containing important information such as UUID, letter number, subject, content, sender, and recipient. These JWT tokens were inserted into the letters as part of the verification mechanism. The Muhammadiyah University of East Kalimantan letter system was updated to verify JWT tokens by extracting the token from the letter and checking the UUID against the database. The research results demonstrate that utilizing JWT tokens as a method for verifying the authenticity of letters provides advantages in terms of efficiency and accuracy. The letter system, which previously relied solely on QR code signatures, can be enhanced by using JWT tokens. The updated letter system can verify letters' authenticity more reliably and dependably, reducing the risks of manipulation or forgery. The utilization of JWT tokens in the Muhammadiyah University of East Kalimantan letter system offers significant benefits in improving the efficiency of the verification process and enhancing the accuracy of letter identification. In this context, this research provides a safer and more effective solution for ensuring the authenticity of letters, thereby enhancing the security and integrity of the letter management system at Muhammadiyah University of East Kalimantan.
