Abstract

Dalam pertanian jagung, sering ditemukan biji jagung yang rusak, yang kusam, yang kotor, dan yang patah akibat proses pengeringan dan pemipilan. Biji jagung yang berukuran lebih kecil dari semestinya juga dapat memperburuk kualitas. Penentuan kualitas biji jagung biasa dilakukan secara manual dengan pengamatan visual. Pemilihan manual membutuhkan waktu yang lama dan menghasilkan produk dengan mutu yang tidak konsisten karena keterbatasan visual, kelelahan, dan perbedaan persepsi masing-masing pengamat. Pada penelitian ini dirancang sebuah sistem klasifikasi untuk mengetahui kualitas biji jagung dengan menggunakan analisis tekstur berbasis pengolahan citra digital, untuk mendapatkan hasil yang tepat dan objektif. Data citra yang diambil yaitu sampel biji-biji jagung menggunakan kamera digital. Algoritma yang digunakan untuk ekstraksi ciri dan klasifikasi kualitas biji jagung menggunakan K-Nearest Neighbour (K-NN). Berdasarkan simulasi secara keseluruhan, maka dapat disimpulkan bahwa sistem dapat mengklasifikasikan biji jagung berdasarkan tiga tingkat kualitas, yaitu kualitas satu, kualitas dua, dan kualitas tiga. Hasil akurasi tertinggi diperoleh pada saat k=3 yaitu sebesar 91,85%.

Abstract

In the era of the industrial revolution 4.0, the development of technological advancements is transforming increasingly sophisticated. The involvement of technology is felt from various aspects of activities and services that utilize information systems through the implementation of using a system. It becomes a threat that creates a crime that places a target on the security of personal data. So that provision and a strong foundation are needed to ensure the integration of data security and confidentiality in responding to threats of attacks and exploitation of information system security from irresponsible parties. Cryptography is a science that studies security techniques in information consisting of various algorithms such as ROT13 and Caesar Cipher. This study used the observation method through community service conducted at SMKN 13 Medan, literature study and mixed methods. The results of this study are able to provide an understanding regarding the security of students' personal data by optimizing the use of the ROT13 and Caesar Ciper algorithms. Through this research, it is hoped that it can become a source of reference on the importance of understanding personal data security so as to increase anticipation of information system security concerning personal data

Abstract

Educational training regarding information technology crime (cyber crime) and its handling is an important step in facing increasingly complex cyber threats. This article discusses the types of cyber crime, its impact, as well as effective handling strategies and methods. This research uses observation methods through community service carried out at SMKS Bina Satria Medan, literature studies and mixed methods. This research uses a qualitative approach with case study methods at several institutions that have implemented this training. The results of this research show an increase in participants' awareness and ability to identify and deal with cyber crime.

Abstract

The digitalization era has brought significant changes in how information is collected, processed, and utilized. One of the key fields in managing this information is data mining. However, many individuals, particularly in educational environments and the general public, still lack a proper understanding of the concepts and practical applications of data mining. This community service activity aims to provide training and basic knowledge about data mining and its benefits in data-driven decision-making. The training targeted teachers and high school students, using a combination of lectures, interactive discussions, and hands-on practice with simple data mining tools. The results showed an increased understanding among participants regarding data mining concepts, workflows, and real-world applications, particularly in education and social contexts. This training is expected to serve as an initial step in building strong data literacy within the community to face the challenges of the digital era intelligently and productively.
