Klasifikasi Citra Alat Musik Marakas, Gitar, dan Drum Menggunakan Metode K-Means dan GLCM
Full text linkThe development of digital image processing technology enables automatic object identification with high accuracy. This study aims to classify images of musical instruments, namely maracas, guitars, and drums, using a combination of K-Means-based color segmentation and Gray Level Co-Occurrence Matrix (GLCM) feature extraction. The process begins with converting RGB images into the Lab color space, followed by object segmentation using the K-Means clustering algorithm to separate the main object from the background. Subsequently, shape features (metric, eccentricity) and texture features (contrast, correlation, energy, homogeneity) are extracted using GLCM. The extracted features are then compared with a feature database using a distance-based approach to determine the object class. Experimental results show that the system can successfully recognize maracas, guitar, and drum images with a satisfactory accuracy level. This research demonstrates that the combination of K-Means and GLCM methods can serve as an effective approach for musical instrument image classification and has the potential to be further developed for object recognition in other fieldsPerkembangan teknologi pengolahan citra digital memungkinkan dilakukannya identifikasi objek secara otomatis dengan tingkat akurasi yang tinggi.

Analisis Perbandingan Kompleksitas Waktu Algoritma Mst Dalam Penyusunan Jaringan Pipa Air Bersih
Full text linkThe availability of clean water is the top priority for the survival of the community. Therefore, efforts are needed to distribute clean water evenly, including by building a pipeline network that reaches every house in an area. The Drinking Water Supply and Sanitation System Management Group (KPSPAMS) of Ulakan Village, Karangasem Regency, built a water pipeline network to overcome the problem of lack of clean water experienced by local residents, especially during the dry season. However, development is still often not optimal because there is a pipe rotation (circuit) that causes the length of the pipe not to be optimized and the overall cost to be higher. Thus, the preparation of an efficient and effective pipeline network is the main focus. The location studied is part of Ulakan Village, Manggis District, Karangasem Regency. This study aims to find the most optimal pipeline network arrangement through a comparison of three Minimum Spanning Tree (MST) algorithms, namely the Kruskal, Prim and Sollin algorithms. This study represents the pipeline graph into an edge list. Furthermore, with the three algorithms, the list is analyzed based on the complexity of time and computer programs to find the Minimum Spanning Tree (MST). This research seeks to provide a practical solution of the comparison of the three algorithms with a focus on theoretical understanding and experimental results.Ketersediaan air bersih menjadi prioritas utama bagi keberlangsungan hidup masyarakat.
