Abstract

Desa Tlogopranoto, Kabupaten Kebumen, merupakan daerah sentra cabai rawit yang memiliki kondisi lahan pasiran sehingga penguapan tinggi dan air mudah terserap. Hal pengairan menjadi tantangan dalam budidaya, mengingat cabai membutuhkan cukup air sedangkan irigasi tidak bertahan lama. Kondisi ini menuntut irigasi yang lebih intensif, yang selama ini mengandalkan listrik konvensional dengan biaya tinggi. Selain itu letaknya yang di pesisir menyebabkan sumber air cukup jauh. Untuk mengatasi tantangan ini dan mendukung keberlanjutan produksi, program pengabdian masyarakat melalui KOSABANGSA dari Universitas Ma'arif Nahdlatul Ulama Kebumen dan Universitas AKPRIND Indonesia memperkenalkan Teknologi Tepat Guna (TTG) berupa Pembangkit Listrik Tenaga Surya (PLTS) atau solar cell untuk sistem irigasi sprinkle pada lahan cabai seluas satu hektar. PLTS ini mengurangi ketergantungan pada listrik konvensional, memudahkan budidaya dan mendukung praktik pertanian ramah lingkungan dengan mengandalkan energi terbarukan. Kegiatan ini mencakup peninjauan kondisi lapang, pemasangan PLTS, pemasangan sprinkle, sosialisasi perawatan PLTS, dan praktek irigasi. Materi lainnya yaitu mengenai efektivitas irigasi pada budidaya cabai lahan pasiran, sehingga didapatkan pengetahuan bagi anggota kelompok tani berupa manfaat adanya teknologi tepat guna dibandingkan cara budidaya sebelumnya. Hasil dari program ini menunjukkan peningkatan kapasitas petani dalam mengelola teknologi irigasi dan budidaya modern, yang diharapkan dapat meningkatkan produktivitas cabai dan pendapatan petani. Secara keseluruhan, penerapan PLTS sebagai solusi irigasi ini menjadi contoh nyata penerapan teknologi berkelanjutan di sektor pertanian, mendukung upaya mitigasi perubahan iklim dan pencapaian target Sustainable Development Goals (SDGs).

Abstract

Abstrak - Penelitian ini bertujuan untuk mengembangkan sistem klasifikasi gerakan semaphore berbasis computer vision dan machine learning yang mendukung pembelajaran visual secara mandiri. Sistem memanfaatkan MediaPipe Holistic untuk mendeteksi titik-titik landmark tubuh dan tangan, serta menggunakan algoritma Random Forest sebagai metode klasifikasi. Dataset dikumpulkan secara langsung dengan merekam gerakan semaphore huruf A hingga Z, kemudian digunakan untuk pelatihan dan pengujian model. Hasil evaluasi menunjukkan performa model yang sangat tinggi, dengan akurasi, precision, recall, dan F1-score mendekati 100% pada kondisi pencahayaan optimal. Namun demikian, hasil ini masih perlu dikaji secara kritis karena keterbatasan variasi data dan perangkat keras, seperti kualitas kamera dan lingkungan pengambilan gambar. Sistem diuji secara real-time dan mampu mengenali pose secara akurat dalam kondisi terang, meskipun akurasi cenderung menurun dalam pencahayaan rendah. Penelitian ini memiliki potensi untuk mendukung pembelajaran semaphore dalam konteks pendidikan kepramukaan, pelatihan militer, maupun inklusi komunikasi visual. Untuk pengembangan ke depan, sistem ini dapat dikombinasikan dengan teknologi text-to-speech (TTS) atau Augmented Reality (AR) guna meningkatkan pengalaman pembelajaran.Kata kunci: MediaPipe Holisti; Random Forest; Semaphore; Computer Vision; Pembelajaran Visual Abstract - This study aims to develop a semaphore gesture classification system based on computer vision and machine learning to support self-directed visual learning. The system utilizes MediaPipe Holistic to detect body and hand landmarks and employs the Random Forest algorithm for classification. The dataset was collected through direct recordings of semaphore gestures from letters A to Z, then used for training and testing the model. Evaluation results show that the model achieved high performance, with accuracy, precision, recall, and F1-score approaching 100% under optimal lighting conditions. However, these results require critical interpretation due to limitations in data diversity and hardware quality, such as camera resolution and environmental conditions. The system was tested in real-time and demonstrated reliable pose recognition in bright environments, although performance decreased in low-light settings. This system shows potential to support semaphore learning in scout education, military training, and visual communication inclusion. Future development may include integration with text-to-speech (TTS) or augmented reality (AR) technologies to enhance the learning experience.Keywords: MediaPipe Holistic; Random Forest; Semaphore; Computer Vision; Visual Learning

Abstract

Dalam era modern, kecerdasan buatan (AI) dan machine learning, khususnya teknik machine learning, telah menjadi integral dalam perkembangan teknologi. Implementasi Convolutional Neural Network (CNN) dalam klasifikasi gambar sering mengalami masalah overfitting, di mana model terlalu beradaptasi dengan data latih dan kurang mampu menggeneralisasi data uji. Untuk mencegah overfitting, penelitian ini menggunakan callback, seperti Early Stopping, Model Checkpointing, dan CSV Logging. Dataset gambar batu-kertas-gunting diperoleh dari Github Dicoding dan diproses dengan pembagian subset, augmentasi data, dan generator data. Model CNN dirancang dengan lapisan konvolusi, lapisan pooling, dan lapisan Dense. Optimizer, fungsi loss, dan metrik evaluasi dipilih sesuai tugas klasifikasi gambar. Melalui pelatihan model, akurasi meningkat dari 48.75% menjadi 98.75%, sementara loss menurun dari 0.9794 menjadi 0.0448. Evaluasi pada data validasi juga menunjukkan peningkatan konsisten. Pelatihan dihentikan pada epoch ke-18 setelah mencapai akurasi di atas 98%, untuk mencegah overfitting dan mengoptimalkan waktu pelatihan. Kesimpulan menunjukkan bahwa penggunaan callback efektif dalam mencegah overfitting dan meningkatkan akurasi model CNN dalam klasifikasi gambar batu-kertas-gunting. Ini menjadi strategi penting dalam meningkatkan kualitas hasil akhir model.
