far the teaching carried out by the teachers of SMA 2 Kisaran is more dominant in learning done face-to-face in the classroom, so that learning requires the mind and energy that is extra because it is done repeatedly in the classroom and the hours that different. Starting from the above, the dedication team sought solutions so that teaching can be acculturated by online learning using blog media to publish teachers' teaching materials to the internet. It is expected that online-based teaching techniques, one of which is outlined in the making and utilization of blogs can stimulate interest from students to access teaching materials that have been published online, both in the form of text, images, audio and learning videos that have been recorded and uploaded by the teacher into his blog whenever and wherever it is, so that it will create student centered learning and learning objectives can be achieved.

Abstrak: Sebagai institusi pendidikan formal maka diperlukan akulturasi teknik dalam Kegiatan Belajar Mengajar (KBM) yang dilakukan oleh masing-masing guru pelajaran untuk dapat mentransfer ilmu pengetahuan kepada peserta didik secara maksimal dan optimal. Selama ini pengajaran yang dilakukan oleh guru-guru SMA Negeri 2 Kisaran lebih dominan ke-pembelajaran yang dilakukan secara tatap muka di dalam kelas, sehingga pembelajaran membutuhkan pikiran dan tenaga yang ekstra karena dilakukan secara berulang-ulang pada kelas dan jam yang berbeda. Berawal dari hal diatas maka tim pengabdian mencari solusi agar pengajaran dapat diakulturasi dengan pembelajaran secara online menggunakan media blog untuk mempublikasikan bahar ajar para guru ke internet. Diharapkan dengan teknik pengajaran berbasis online salah satunya yang dituangkan dalam pembuatan dan pemanfaatan blog dapat merangsang minat dari para siswa untuk mengakses bahan ajar yang telah dipublikasikan secara online baik informasi berupa text, gambar, audio maupun video pembelajaran yang telah direkam dan diupload oleh guru ke dalam blognya kapan dan dimanapun berada, sehingga akan tercipta pembelajaran berpusat pada siswa (Student Centred Learning) dan tujuan pembelajaran dapat tercapai.

e the economy of the people in an area because the yields produced can provide economic benefits. The Asofa Foundation tried to capture this opportunity in the context of developing a masjid-based economy through hydroponic training for the surrounding community. Therefore, a series of training was conducted to improve the capacity of the community. The training included training on seeding vegetables in rockwool, training on transplanting, and training in preparing and mixing hydroponic fertilizers. The results of the training were that residents were able to cultivate plants using hydroponics. However, the boundary was the environmental conditions (in this case water) in Bekasi which were not good enough so that the seedlings died after being transplanted into the hydroponic kit. Further training needed can be in the form of training fruit plants using hydroponics which can withstand inadequate water conditions. Another training that can be carried out is training in vegetable cultivation with planting methods other than hydroponics that are able to accommodate environmental conditions

Abstrak: Pertanian perkotaan adalah menanam dan memelihara binatang ternak di dalam atau sekitar kota. Beragam jenis tanaman dapat dibudidayakan terutama tanaman sayuran dan buah. Pertanian perkotaan mampu membantu peningkatan ekonomi rakyat di suatu daerah karena hasil panen yang dihasilkan dapat memberikan keuntungan ekonomis. Peluang inilah yang berusaha ditangkap oleh Yayasan Asofa dalam rangka pengembangan ekonomi berbasis masjid lewat pelatihan hidroponik untuk masyarakat sekitar. Oleh karena itu, dilakukanlah serangkaian pelatihan untuk meningkatkan kemampuan masyarakatnya. Pelatihan yang dilakukan antara lain pelatihan penyemaian tanaman sayuran di rockwool, pelatihan pindah tanam, dan pelatihan meracik pupuk hidroponik. Hasil dari pelatihan tersebut adalah warga mampu melakukan budidaya tanaman dengan menggunakan hidroponik hanya saja kondisi lingkungan (dalam hal ini air) di daerah Bekasi kurang baik sehingga tanaman semaian mati setelah dipindahkan ke dalam kit hidroponik. Pelatihan lanjutan yang diperlukan dapat berupa pelatihan tanaman buah dengan menggunakan hidroponik yang tahan kondisi air yang kurang memadai. Pelatihan lain yang dapat dilakukan adalah pelatihan budidaya tanaman sayuran dengan metode tanam selain hidroponik yang mampu mengakomodasi kondisi lingkungan.

achine learning algorithms Support Vector Machine (SVM), Random Forest, and Naive Bayes for automated sentiment classification of Indonesian-language mobile application reviews. A dataset of 3,000 user reviews from the RupaRupa application on the Google Play Store was collected and preprocessed through normalization, tokenization, stopword removal, and stemming. TF-IDF vectorization was applied for feature extraction, while the Synthetic Minority Over-sampling Technique (SMOTE) was used to address class imbalance across three sentiment categories: positive, negative, and neutral. The results show that SVM achieved the highest accuracy of 90.02%, while Random Forest obtained the best F1-score of 88.08% when sufficient training data were available. Naive Bayes demonstrated relatively stable performance across varying training data sizes. Furthermore, TF-IDF keyword analysis revealed that negative reviews were primarily associated with delivery issues, technical problems, and pricing concerns. These findings demonstrate the effectiveness of machine learning approaches for sentiment classification and provide practical insights for improving mobile application services.

e commonly used for image upscaling; however, these approaches often produce blurred images, lose fine textures, and fail to reconstruct complex visual structures. This study aims to enhance digital image resolution by employing a deep learni based approach using a Low-Light Convolutional Neural Network (LLCNN) built upon a Deep Neural Network (DNN) architecture. The dataset used in this study is the DIV2K dataset, which consists of 1,000 high-resolution images. These images were downsampled using scaling factors of ×2, ×3, and ×4 to generate paired Low Resolution–High Resolution (LR–HR) data for training and evaluation. The proposed LLCNN is designed to extract important features such as edges, textures, and local patterns through multiple convolutional layers, followed by non-linear mapping to reconstruct high-resolution images more accurately. Quantitative performance evaluation was conducted using the Peak Signal-to-Noise Ratio (PSNR) and the Structural Similarity Index (SSIM). Model performance was evaluated quantitatively using the Peak Signal-to-Noise Ratio (PSNR) metric. Experimental results showed that the proposed method improved image quality compared to the bilinear method. These results indicate that the deep learning based approach effectively improves image sharpness and structural fidelity, thereby demonstrating its potential for digital image resolution enhancement.

Abstrak: Permasalahan utama dalam pengolahan citra digital adalah keterbatasan resolusi yang menyebabkan detail visual sulit dipertahankan ketika citra diperbesar. Metode konvensional seperti Bilinear Interpolation masih banyak digunakan, namun sering menghasilkan citra buram, kehilangan tekstur halus, serta tidak mampu merekonstruksi struktur visual yang kompleks. Penelitian ini bertujuan untuk meningkatkan kualitas resolusi citra digital dengan memanfaatkan pendekatan deep learning berbasis Low-Light Convolutional Neural Network (LLCNN) yang dibangun di atas arsitektur Deep Neural Network (DNN). Data yang digunakan dalam penelitian ini berasal dari dataset DIV2K, yang terdiri dari 1000 citra beresolusi tinggi. Citra tersebut diturunkan menjadi resolusi rendah menggunakan faktor downsampling ×2, ×3, dan ×4 untuk membentuk pasangan data Low Resolution–High Resolution (LR–HR) sebagai data pelatihan dan pengujian. LLCNN dirancang untuk mengekstraksi fitur-fitur penting seperti tepi, tekstur, dan pola lokal melalui beberapa lapisan konvolusi, kemudian melakukan pemetaan non-linear guna merekonstruksi citra resolusi tinggi secara lebih presisi. Evaluasi performa model dilakukan secara kuantitatif menggunakan metrik Peak Signal-to-Noise Ratio (PSNR). Hasil eksperimen menunjukkan bahwa metode yang diusulkan mampu meningkatkan kualitas citra dibandingkan metode bilinear. Hasil ini membuktikan bahwa pendekatan berbasis deep learning efektif dalam meningkatkan ketajaman dan kesesuaian struktur citra digital.
