SIGEMPA, sebuah sistem peringatan dini gempa bumi berbasis IoT dengan ESP32, diinisiasi sebagai respons terhadap kebutuhan akan peringatan dini yang efisien dan mudah digunakan bagi masyarakat Indonesia yang sering terdampak oleh bencana alam, termasuk gempa bumi. Meskipun negara telah menyediakan alat Sistem Peringatan Dini (Early Warning System/EWS), namun penggunaannya belum merata dan seringkali mengharuskan masyarakat untuk menunggu informasi dari instansi terkait. Dalam konteks ini, SIGEMPA dirancang sebagai solusi yang dapat memberikan peringatan dini secara real-time dan mudah diakses oleh masyarakat.
 
 Penelitian ini mencakup perancangan dan implementasi sebuah perangkat pengukur gempa bumi yang menggunakan ESP32 dan Telegram berbasis IoT, dengan tujuan mengikuti arus digitalisasi era 4.0. Melalui studi eksperimen yang dilakukan, perangkat ini berhasil diprogram dan diuji coba, menggunakan komponen seperti sensor gempa dan ESP32. Dengan bantuan ESP32, SIGEMPA mampu mendeteksi aktivitas gempa bumi dan mengirimkan notifikasi peringatan secara real-time melalui Telegram. Perangkat juga dilengkapi dengan kategori peringatan "GEMPA" dan "AMAN", yang diindikasikan oleh parameter tertentu, sehingga memungkinkan pengguna untuk mendapatkan informasi terkait risiko gempa bumi dengan lebih jelas dan cepat.

Student graduation becomes a separate assessment reference in a higher education institution. Things that are taken into consideration are efforts to carry out assessments to determine the best students. The data used comes from the graduation achievements of students from the Nursing Profession Study Program, Faculty of Nursing, Muhammadiyah University, East Kalimantan, which consists of four criteria. Based on these problems, the author conducted research aimed at analyzing the use of Decision Support System methods. The method used in this research uses a combination of AHP-SAW and AHP-TOPSIS. The results obtained explain that both methods obtain ranking results in the same order even though the Priority value of each method is different. Where rank 1 for each method is A1 with an AHP-SAW Priority Value of 100 and AHP-TOPSES of 1, likewise in the next ranking order.

The development of technology and the internet has triggered a significant transformation in consumer behavior, especially in the context of electronic commerce. This research aims to address growing market needs by developing a web-based online sticker shop application. This application is designed to provide convenience in the process of selling and purchasing stickers, optimize user experience, and increase product accessibility via online platforms. The development method used in this research involves the application of web technologies such as HTML, CSS, JavaScript, and PHP. This approach allows building systems in a structured and organized manner, with a focus on features that support intuitive user interaction. Some of the key features implemented include informative product pages, an efficient shopping cart system, and transaction history to provide transparency and order tracking for consumers. The result of this research is an online sticker shop application that not only makes the sales process easier for sellers, but also provides a comfortable online shopping environment for buyers. It is hoped that this application can increase efficiency in sales management, increase the competitiveness of the sticker business, and make a positive contribution to the growth of the e-commerce industry. As an innovative solution, this application is expected to be able to keep up with market trends and provide a satisfying online shopping experience for users.

PT. Sinar Kencana Jaya Abadi is a company engaged in sanitary sector since 1995. With advances in technology, of course, marketing is not only in physical form, but also in digital forms, such as websites. Created a useful website to increase sales. The website was created so that people can find out more about what field this PT is engaged in, as well as the background of this PT. Sinar Kencana Jaya Abadi. This website was developed using the CodeIgniter framework, and the use of MySQL as a database. This research is useful for introducing PT Sinar Kencana Jaya Abadi to various external customers, so that it can be easier to find out what is being traded. The results of the study found that the application system functions properly and properly so that the application system can be checked out and stored shipping data into a database.

Learning is the result of an interactive process that takes place between educators and students in a learning environment. For students, a learning tool is needed to help them prepare and improve the various types of material that will be studied directly at school. One form of learning facility is tutoring or usually abbreviated as tutoring. Tutoring is an effort provided by guidance teachers in dealing with and solving learning problems experienced by students. Tanry Education Center is a tutoring institution that offers various levels of education, from kindergarten to high school/vocational school. However, Tanry Education Center has so far still used conventional methods in conducting test, so students have to wait a few days to get their exam results due to time constraints and there are times when students cannot know the correct answer to the given questions. To overcome this problem, research was carried out with the aim of developing and building an online exam system application. The purpose of this application is to assist users in measuring the level of understanding of students' material in Tanry Education Center using a Web-based platform. This research will use the Prototype development methodology and be implemented using the PHP programming language utilizing the CodeIgniter 4 framework. A black box approach will be used to carry out application testing, with a focus on evaluating software functionality.

Mushrooms, as eukaryotic organisms that dominate the kingdom Fungi, play a crucial role as decomposers of organic matter in ecosystems. The diversity of mushrooms encompasses a variety of species, ranging from microscopic to macroscopic, widely distributed in various environments. Superficial fungal infections, or superficial mycoses, focus on fungal infections limited to the surface of the skin, nails, or hair. Such infections are typically localized, not penetrating deep into tissues and remain primarily a local condition. In the context of this study, the optimal model developed through training successfully achieved a validation accuracy of 92.590% and a training accuracy of 88.933%. Evaluation results indicate a precision value of 94%, a recall value of 93%, and an F1-score value of 92%. These findings highlight the success of the model in classifying and evaluating superficial fungal infections with high precision.

The proposed office door security system combines RFID (Radio-Frequency Identification) Sensor and PIR (Passive Infrared) Sensor technology with Telegram-based communication. The design of this system requires RFID and PIR sensors to be formed in order to produce a system design that is made to meet the needs of system users. The aim of this system is to increase the security level of access to office space by combining identification of access owners via RFID cards and motion detection using PIR sensors. Communication through the Telegram platform is used to provide real-time notifications to access owners when there is activity at the office door. The control system for this device is controlled by the Esp32 Microcontroller, using 4 inputs, namely Rfid, PIR, Keypad and telegram sensors, as well as 5 outputs, namely Selenid Doorlock, Buzzer, LCD, Relay and telegram. By using the esp32 microcontroller to process data and the telegram application for IoT as a link between devices and smartphones. With 2 sensors as logic inputs for the esp32 microcontroller, the number of outputs that occur is 5, namely in the form of a sound from a buzzer as a warning, and a PIR as a sensor to open the door from the inside. When opening the RFID with a card tag, then the selenoid doorlock will open. Overall, the design of this office door security system has the potential to improve security and monitoring in the office space. By combining the technology of RFID sensors, PIR sensors and Telegram-based communication, this system enables accurate identification, real-time motion detection and fast interaction between the security system and the access owner. So that Telegram is successful in sending notifications if someone enters, that is, they will appear. "User Name Open Door: according to the registered UID", but if it fails "Unregistered User Failed Login Attempt" The LCD will also issue an output if someone has registered their RFID tag or not
