Abstract

Sasirangan as the Banjar people's creative work is a typical icon of South Kalimantan and Widely known for its patterns and uniqueness which highly demanded by local, national and foreign people. Sasirangan textile marketing using the marketplace, Sasirangan image with patterns of different colours have large storage capacity, as well as uploading images of Sasirangan patterns in e-commerce requires large bandwidth, while the constraints on MSME entrepreneurs have limited Internet bandwidth access. Image compression aims to convert data files into smaller files for efficient storage and effective data transmission. The vector quantization method is a mapping of image data in the form of irregular bits, so the mapping uses the fuzzy C-mean algorithm. The achieved compression kulat kurikit.jpg is higher than that of other images, with a compression ratio of 88.5233600% and a file size of 566 KB. a better quality than the others due to its more uniform grey scale colour composition for the same block vector and codebook.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan literasi teknologi melalui pelatihan troubleshooting dan perbaikan laptop bagi anggota Pergerakan Mahasiswa Islam Indonesia (PMII) Banjarbaru. Seiring dengan perkembangan teknologi, laptop menjadi alat penunjang utama dalam aktivitas akademik dan organisasi. Namun, minimnya pemahaman tentang perawatan laptop dan penanganan masalah teknis seringkali menghambat produktivitas. Berdasarkan observasi awal, banyak anggota PMII Banjarbaru yang mengalami kesulitan dalam mengatasi masalah teknis pada laptop, seperti gangguan hardware (misalnya, baterai lemah, layar blank, atau keyboard rusak) dan masalah software (misalnya, sistem operasi error, virus, atau kinerja lambat). Hal ini menyebabkan ketergantungan pada layanan servis yang mahal dan tidak selalu tersedia di Kota Banjarbaru. Pelatihan ini dirancang untuk memberikan pengetahuan praktis dan keterampilan teknis kepada peserta melalui metode ceramah interaktif, demonstrasi, dan praktik langsung. Materi pelatihan mencakup: (1) pengenalan komponen hardware dan software laptop, (2) teknik dasar troubleshooting untuk mengidentifikasi masalah, (3) langkah-langkah perbaikan masalah umum pada laptop, dan (4) tips perawatan laptop untuk mencegah kerusakan. Peserta juga akan diberikan panduan tertulis yang dapat digunakan sebagai referensi mandiri.
