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

Access to global information online is essential for an institution or group. Users who use web-based apps from their homes or other locations may meet their requirements without traveling to the designated institution. This study aims to determine if stakeholders' demands can be met by the web-based application for tuition fee management at the Islamic boarding school "Bilal Bin Rabah" in Sukoharjo. Both documentation and UML (Unified Modeling Language) modeling techniques were employed in this study. The purpose of this application is to make it simpler for administrative staff to handle information on student fee payments and to evaluate financial information for associated parties. Three people may use this application's payment system: the administrator, the head of the Islamic boarding school, and a parent of a student. The administrator may handle student information, and payment information, charge the student’s parents, and print the necessary reports for the Islamic Boarding School. The school's headmaster has access to student data and may generate reports and examine student invoices. The invoices and transaction history of payments that have been made are visible to parents/guardians of students. The website will continue to be developed to support the mobile platform, allowing users to access the school fee management system via mobile more conveniently. Based on the test results, users of the SPP payment system application are quite satisfied.

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.

Abstract

Grass is a one-piece plant with thin, tapering leaves that grow from the base of the stem. Grass is one of the most common types of plants on earth, but not all types are the same. Some need regular care, while others can grow without ever being touched. There are various types of grass, but only a few types of grass are suitable as ornamental plants. Currently, garden construction service providers still use a manual system to determine the type of grass, so errors can occur, resulting in damage to the garden and a decrease in the artistic value and selling price of the grass. A technology can help determine the type of grass for making a garden, namely a decision support system. This system was built on a web basis using the Multi-Objective Optimization on the Basis of Ratio Analysis method to recommend types of grass for making gardens. This research uses 17 types of grass as alternative data and five selection criteria, namely leaf shape, growth rate, weather resistance, leaf color, care, leaf texture and price per meter. This method's research shows Japanese grass as the best alternative with the highest optimization value, namely -0.02499. The results of system validation using the Confusion Matrix method to compare system calculations with manual calculations obtained an accuracy value of 71%.
