Abstract

Face recognition has become a common thing used in the field of surveillance and security in computer technology and image devices. This study aims to identify the usefulness of a person's face on 3 test images. This study examines the methods of cropping techniques, image enhancement through intensity measurement, and histogram analysis to improve the contrast and distribution of image intensity. In addition, the Viola-Jones algorithm is used to detect key facial features such as eyes, nose, and mouth. The results of the analysis are then applied in the feature evaluation stage, where usually between facial features are applied to measure the ratio of facial proportions. Furthermore, the comparison of proportional ratios of several images was analyzed using bar graphs and line graphs to evaluate the trend and stability of facial proportions. The results showed the best ratio stability with a smaller variation of the on-off ratio of image 2 which is 0.4762 pixels to 0.4983 pixels. Image 2 is the most ideal for face measurement systems based on geometric ratios because it provides more consistent and visible results.

Abstract

Perkembangan kecerdasan pada siswa sekolah dasar terutama dalam aspek daya ingat dan kecepatan respons merupakan fondasi penting dalam proses pembelajaran. Namun, metode konvensional yang bersifat monoton dan kurang melibatkan aspek sensorimotor seringkali menurunkan motivasi dan minat belajar siswa. Untuk itu, penelitian ini merancang dan membangun sebuah permainan interaktif “Simon Says” berbasis mikrokontroler yang dirancang khusus untuk meningkatkan daya ingat dan kecepatan respons siswa SD. Mode pertama berfokus pada peningkatan respon dan fokus melalui rangkaian perintah yang harus dilakukan. Mode kedua menitik beratkan pada peningkatan daya ingat. Terakhir mode 3 menggabungkan focus dan daya ingat. Diharapkan inovasi ini tidak hanya meningkatkan aspek kognitif siswa meliputi working memory dan reaksi sensorimotor tetapi juga memacu minat belajar anak yang selama ini rendah akibat metode tradisional yang membosankan

Abstract

Abstrak: Varietas padi Cisokan Kubang merupakan komoditas unggulan daerah Nagari Kubang yang memiliki potensi ekonomi tinggi, namun pemanfaatan teknologi digital oleh petani masih terbatas, terutama dalam akses informasi pertanian, pemasaran, dan pengelolaan usaha tani secara modern. Harga komoditas pertanian yang cenderung fluktuatif, keterbatasan akses ke pasar yang lebih luas juga menjadi kendala, di mana hasil pertanian hanya dipasarkan di sekitar daerah tanpa ada pengembangan distribusi yang lebih besar. Tujuan dilakukannya pengabdian ini yaitu meningkatkan literasi digital, kemampuan branding dan pemasaran produk secara online melalui sosialisasi dan pelatihan kepada kelompok tani yang terdiri dari 10 anggota dalam meningkatkan produktivitas hasil komoditas unggulan daerah. Metode pelaksanaan meliputi pelatihan penggunaan smartphone secara efektif, pemanfaatan internet untuk memperoleh informasi pertanian, pembuatan konten promosi digital, serta pengenalan marketplace dan media sosial sebagai sarana pemasaran. Evaluasi dilakukan menggunakan angket dan wawancara pasca kegiatan. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan petani menggunakan literasi digital untuk meningkatkan produktivitas sebesar 85%. Program ini menunjukan peningkatan kemampuan kelompok tani dalam menerapkan teknologi digital.Abstract: The Cisokan Kubang rice variety is a superior commodity in the Kubang Nagari region with high economic potential. However, farmers' use of digital technology is still limited, especially in accessing agricultural information, marketing, and modern farming management. Fluctuating agricultural commodity prices and limited access to wider markets are also obstacles, where agricultural products are only marketed within the surrounding area without any development of wider distribution. The purpose of this community service is to improve digital literacy, branding skills, and online product marketing through outreach and training for farmer groups consisting of 10 members in increasing the productivity of the region's superior commodities. Implementation methods include training in effective smartphone use, utilizing the internet to obtain agricultural information, creating digital promotional content, and introducing marketplaces and social media as marketing tools. Evaluation was conducted using questionnaires and post-activity interviews. The results of the activity showed an increase in farmers' knowledge and skills in using digital literacy to increase productivity by 85%. This program demonstrated an increase in the ability of farmer groups to apply digital technology.

Abstract

Waste is a very serious environmental problem commonly faced by Indonesians. According to data from the National Waste Management Information System (SIPSN), Indonesia's waste volume reached 20.02 million tons in 2022. In Indonesia, the amount of waste generated reached 65 million tons per day in 2016 and increased to 66.5 million tons in 2018. The amount of waste in Indonesia continues to increase annually. In large cities, waste management is an increasingly pressing challenge, given the negative impacts caused by improper management, such as waste accumulation in landfills (TPA), water and air pollution, and public health issues. This study aims to design and implement an automatic waste classification system based on Computer Vision technologies as a solution for urban waste management. The system utilizes an Arduino Mega 2560, camera, ultrasonic sensor, servo motor, and conveyor to detect and classify five main types of waste: plastic, paper, glass, metal, and organic materials in real time. The camera captures images of waste, which are then analyzed using a Computer Vision model, while sensors and actuators control the flow and physical sorting process. This research seeks to improve waste processing efficiency by reducing human involvement in hazardous tasks and to promote the application of intelligent technologies in supporting sustainable recycling systems and reducing the burden on final disposal sites (landfills). The system created can detect and classify waste types well.
