Abstract:Mango Gadung Clonal 21 (Mangifera indica L.) is the result of crossbreeding between Gadung Mango and Arumanis, acknowledged as a native fruit of Pasuruan Regency. However, the sales of this fruit decline during the peak…
harvest season, causing difficulties for farmers in processing ripe fruit. Therefore, technology is needed to enhance shelf life and create innovative products using Mango Gadung Clonal 21 (Mangifera indica L.) as the base ingredient, with the addition of antioxidants from red dragon fruit peel. The aim of this research is to assess the physicochemical and organoleptic characteristics and identify the best combination of adding dextrin and red dragon fruit peel to Mango Gadung Clonal 21 (Mangifera indica L.) powder. This study employed a randomized block design with two main factors: the addition of red dragon fruit peel extract (M) with 2 levels (15 grams and 20 grams) and the addition of dextrin (D) with 3 levels (15 grams, 20 grams, and 25 grams). The study was repeated three times, resulting in a total of 18 treatments. Analysis encompassed antioxidant activity, water content, solubility, as well as organoleptic evaluations of color, aroma, taste, and texture. The best results were observed in the M1D3 treatment (15 grams of red dragon fruit peel and 25 grams of dextrin), with an antioxidant activity of 58.96 mg/ml, water content of 9.15%, solubility of 79.31%, color rating of 3.56 (liked), taste rating of 3.8 (liked), aroma rating of 3.04 (somewhat liked), and texture rating of 3.76 (liked).

tion of sustainable lifestyles; however, its dissemination is often presented in a textual manner that is less engaging for the general public. This study proposes an interactive visual approach utilizing projection mapping technology through Resolume Arena software to create an immersive educational stage performance. The animated visuals are narratively designed to enhance audience understanding of the 3R concept. The simulation results indicate that this approach has strong potential to improve audience engagement and information retention across diverse age groups.

Abstrak: Pendidikan lingkungan menjadi salah satu pilar penting dalam membentuk kesadaran masyarakat akan isu keberlanjutan. Konsep 3R (Reduce, Reuse, Recycle) telah lama menjadi strategi utama dalam mengelola sampah dan mendukung gaya hidup berkelanjutan. Namun, penyampaian informasi mengenai 3R masih sering bersifat tekstual dan kurang menarik bagi masyarakat umum. Dalam studi ini, dikembangkan pendekatan visual interaktif melalui teknologi projection mapping menggunakan perangkat lunak Resolume Arena untuk menciptakan pertunjukan panggung edukatif yang imersif. Visual animasi dirancang secara naratif untuk menstimulasi pemahaman audiens terhadap konsep 3R. Hasil simulasi menunjukkan bahwa pendekatan ini berpotensi besar dalam meningkatkan keterlibatan dan retensi informasi pada audiens dari berbagai usia.

Abstract:Abstract: This study aims to classify the nutritional status of toddlers based on anthropometric data using the K-Nearest Neighbor (KNN) algorithm. Data were obtained from 20 Integrated Health Posts (Posyandu) in Rumbai…
Timur District, including Lembah Sari Village and Limbungan Village with a total of 1,000 toddler data. After cleaning and preprocessing, 782 data were obtained ready for use. The preprocessing stages include data cleaning and transformation, outlier removal, minority class handling, and data normalization. Next, data balancing was carried out using the Synthetic Minority Oversampling Technique (SMOTE) to address class imbalance. The data was divided into 80% training data and 20% test data, then the K parameter was tested from 1 to 15 using 5-fold cross-validation. The results showed that the value of K = 1 provided the best performance with a macro recall of 0.8827 and an accuracy of 86.26%. These results indicate that the combination of the KNN algorithm with the SMOTE method and Min-Max normalization is effective in improving classification performance on imbalanced data and producing accurate and balanced predictions of toddler nutritional status between classes.

Abstrak: Cyberbullying telah menjadi isu yang semakin mendesak di kalangan remaja, yang menggeser banyak interaksi sosial ke platform digital. Penelitian ini menyelidiki faktor-faktor yang berkontribusi terhadap cyberbullying dan dampak jangka panjangnya terhadap siswa di SMAN 15 Batam. Dengan menggunakan pendekatan deskriptif kuantitatif, data dikumpulkan melalui survei yang dilakukan terhadap 52 siswa dari berbagai kelompok umur dan tingkat kelas. Temuan menunjukkan bahwa sebagian besar siswa telah mengalami dampak negatif yang signifikan dari cyberbullying, yang berdampak pada kesehatan mental, kinerja akademik, dan hubungan sosial mereka. Faktor-faktor utama yang berkontribusi terhadap hal ini adalah ketidakstabilan emosi, tekanan teman sebaya, stres akibat pembelajaran jarak jauh, dan terbatasnya aktivitas sosial selama pandemi. Studi ini menyoroti bahwa bentuk-bentuk cyberbullying yang paling umum melibatkan pelecehan verbal, ejekan terhadap penampilan fisik, dan peniruan identitas. Mengingat besarnya dampak terhadap kesejahteraan siswa, program intervensi yang lebih kuat yang melibatkan sekolah, keluarga, dan komunitas sangat penting untuk mengurangi dampak berbahaya dari cyberbullying dan menciptakan lingkungan digital yang lebih aman bagi remaja.

he authority of the Province of North Sumatra, has 111 students across elementary, junior high, and senior high school levels. SLBN Tanjungbalai is led by Mrs. Resti, S.Pd., supported by 13 teachers and 1 administrative staff member. This media integrates an interactive kinesthetic system, binary Braille sensors, and artificial intelligence (AI) capable of recognizing Braille letter patterns based on tactile input and providing real-time voice feedback. Braille letters are converted into six-dot binary codes (Braille-cell), such as A (100000), B (110000), C (100100), D (100110), up to Z (101011). These binary combinations are detected by tactile sensors or push buttons, then processed by an ESP32S connected to a 2004 LCD with I2C, a DFPlayer Mini, and a speaker to produce the corresponding letter sounds. The socialization activity was conducted at SDLB Negeri Kota Tanjungbalai, involving companion teachers and eight blind students. The activities included device demonstration, usage training, and interactive trials. The results show positive responses from both teachers and students, as the media enhances motivation, accuracy, and speed in learning Braille letters. RICKI-Braille proved to be more interactive and adaptive compared to conventional Braille learning media.

Abstrak: Media Reading And Interaction Console With Kinetic Intelligence – Braille versi prototipe bertujuan memperkenalkan inovasi teknologi pendidikan bagi peserta didik tunanetra di SLB Negeri Kota Tanjungbalai. Sekolah yang berada di bawah naungan Provinsi Sumatera Utara ini memiliki 111 siswa dari jenjang SD, SMP, hingga SMA. SLBN Tanjungbalai dipimpin oleh Ibu Resti, S.Pd., dengan dukungan 13 guru dan 1 tenaga tata usaha. Media ini memadukan sistem kinestetik interaktif, sensor Braille biner, dan kecerdasan buatan (AI) yang mampu mengenali pola huruf Braille berdasarkan input titik-titik taktil, kemudian memberikan umpan balik suara secara real-time. Huruf Braille dikonversi menjadi kode biner enam titik (Braille-cell), misalnya A (100000), B (110000), C (100100), D (100110), dan seterusnya hingga Z (101011). Sensor taktil atau push button membaca kombinasi biner tersebut, lalu memprosesnya melalui ESP32S yang terhubung dengan LCD 2004 + I2C, DFPlayer Mini, dan speaker untuk menghasilkan suara huruf yang sesuai. Sosialisasi dilakukan di SDLB Negeri Kota Tanjungbalai dengan melibatkan guru pendamping dan delapan siswa tunanetra. Kegiatan mencakup demonstrasi alat, pelatihan penggunaan, serta uji coba interaktif. Hasilnya, guru dan siswa memberikan respons positif karena media ini meningkatkan motivasi, ketepatan, dan kecepatan belajar huruf Braille. RICKI-Braille terbukti lebih interaktif dan adaptif dibanding media Braille konvensional.
