Nowadays, increasingly rapid technological developments encourage learning progress. However, the method still used remains the same, namely using textbooks and modules. Actually, this method is quite good because the learning system is more technical and structured. In reality, what happens is the opposite, because the increasingly rapid development of technology makes children lazy to read books and more interested in playing games on smartphones. So there is no interest in children learning. Therefore, the author took the initiative to create an interactive and efficient learning media application that can be accessed from a smartphone. It is hoped that this application can increase children's desire to learn starting from an early age, especially at the Coastal Children's Education Center (REDAKSI). The application created is a Reading, Writing and Counting (calistung) learning application aimed at children under the age of ten. This application was created using Unity and contains several learning menus in the application.

Abstrak Alat kontrasepsi adalah suatu cara atau metode yang bertujuan untuk mencegah pembuahan sehingga tidak terjadi kehamilan. Permasalahan yang terjadi pada pasangan usia subur saat ini cukup banyak, sementara pertumbuhan penduduk tidak seimbang dengan pertumbuhan lapangan kerja, maka seharusnya pasangan usia subur tersebut mengenal alat kontrasepsi untuk tindakan atau usaha mencegah terjadinya kehamilan dan jarak antara anak yang pertama dengan yang berikutnya. Saat ini ada banyak alat, metode dan jenis alat kontrasepsi. Berdasarkan masalah tersebut, perlu dicarikan upaya untuk memecahkan masalah tersebut. Sehingga penulis ingin memecahkan permasalahan yang terjadi, yaitu membangun sistem pendukung keputusan untuk membantu peserta program keluarga berencana dalam memilih alat kontrasepsi. Dalam perancangan sistem penulis menerapkan metode untuk mendapatkan hasil output atau keluaran yang maksimal. Metode yang digunakan oleh penulis adalah metode Profile Matching (PM) adalah adalah sebuah mekanisme pengambilan keputusan dengan mengasumsikan bahwa terdapat tingkat minimal yang harus dipenuhi atau dilewati. Hasil penelitian ini mencapai beberapa temuan penting dalam pengembangan sistem pendukung keputusan untuk memilih alat kontrasepsi dalam konteks program keluarga berencana. Diharapkan hasil penelitian ini dapat berkontribusi pada pengurangan angka kehamilan yang tidak diinginkan, peningkatan pemahaman masyarakat tentang metode kontrasepsi, serta memberikan kendali lebih besar kepada individu dalam perencanaan keluarga mereka, mendukung tujuan program keluarga berencana secara efektif.

As the field of information and communication technology continues to evolve, the potential for digital crimes increases significantly. Information technology plays a key role in facilitating various human activities in the fields of communication and data exchange. The use of digital data, such as documents, photos, videos, and audio, still creates many challenges in proving ownership.. The proliferation of social media platforms like Facebook, Instagram, and TikTok has made it easier for individuals to duplicate, damage, or even steal content, often for malicious purposes related to copyright infringement.To secure digital image data, the technique of fidelity watermarking using Discrete Fourier Transform (DFT) and cryptographic authentication with the Rivest-Shamir-Adleman (RSA) algorithm can be utilized. Watermarking is a technique that embeds information into an image, serving to provide identification marks and secure copyright information. This process does not damage the original image quality. DFT is a watermarking technique that has the capability to convert the image back to the spatial domain after embedding the watermark. On the other hand, RSA is a cryptographic technique that enables data encryption using a public key and decryption with a private key. In the context of image watermarking, RSA is used to secure the watermark information embedded within the image. Watermark information that is encrypted using the public key can only be accessed or decrypted by the party possessing the private key. This enhances the security of the watermark and ensures that the information embedded within the image remains safe, even if the image is shared.

The rapid development of technology has influenced various aspects of education, including data management in schools. One of the key aspects of vocational education is efficient data processing to support administrative and academic activities. This community service program was conducted to provide students of SMK Swasta Nur Azizi with knowledge and skills in utilizing MySQL as a database management system for data processing. MySQL was chosen for its capability to efficiently manage and process data, making it highly relevant to industry needs. This program employed a qualitative approach with a case study method, focusing on the implementation of MySQL in student data processing. Data were collected through interviews, observations, and documentation to analyze the effectiveness of MySQL in school operations. The activities included socialization sessions covering theoretical explanations of MySQL fundamentals, software installation, and hands-on practice in database creation and SQL queries. The results of this program indicate that students were able to understand the basic concepts of MySQL, create databases and tables, and process data using fundamental SQL commands such as SELECT, INSERT, UPDATE, and DELETE. Thus, this initiative is expected to enhance students' data processing skills, enabling them to apply these competencies in various fields and strengthen their qualifications in the job market.

The advancement of digital technology has driven the development of Internet of Things (IoT)-based learning systems to enhance efficiency and interactivity in the teaching and learning process. IoT implementations is the development of a sensor-based keyboard learning system. This system is designed to help users improve their typing skills through monitoring parameters such as typing speed, keypress patterns, and usage duration. This data becomes an important asset that requires protection due to its connection to user privacy and personal performance evaluation. In IoT-based systems, data is typically transmitted through networks that are potentially vulnerable to security threats, such as eavesdropping, modification, or theft of data or information. The development of this system is carried out in a sensor-based keyboard learning application with IoT integration, which is equipped with data security features using steganography techniques. Steganography is a technique used to hide data or information within a digital medium so that it cannot be accessed by others. The method used is the Most Significant Bit (MSB), a simple steganography algorithm that utilizes significant bits from image files to embed secret messages. This research aims to analyze the effectiveness of the MSB method in protecting user data stored and transmitted through IoT system. The implementation is carried out on a sensor-based keyboard learning system, where the data collected from the sensors is used to track typing speed, keypress patterns, and typing duration. This data is encrypted using MSB steganography and embedded into a cover image before being transmitted through the IoT network.
