Abstract

Lontar is a traditional Balinese manuscript with a Balinese script in it. Balinese traditional manuscripts can be more than 100 years old. The age factor of the Balinese manuscript has an impact on the Balinese script in it. Balinese script that has been written more than 10 years tends to be darker. This makes Balinese script not visible well, and this affects the image quality of the manuscript. This thing becomes the main issue in this research, Balinese script detection on Balinese manuscript images. the first of all is image processing using edge detection, canny and Sobel becomes the main algorithm of this process. After image processing, the Balinese manuscript will be processed with the findcontour method to detect an object that contains in it. The final process of this detection system is to separate detected objects into three main groups namely noise object, Balinese script object, and hole object. Application (Balinese script object detection system) is more accurate in detecting Balinese script objects in Balinese script under 1 year (new script), it tends to be more likely to find noise/dirt. This is because the writing of the lontar using a pencil first before using the knife media. This adds to the noise or dirt detected by the application The findcontour method can detect Balinese script objects with a detection result of 30% - 70% Balinese script objects.

Abstract

Keterbatasan sarana dalam pembelajaran kimia dapat mempengaruhi proses pembelajaran yang dilakukan kurang maksimal, sehingga penting untuk melakukan inovasi untuk keterbatasan laboratorium tersebut. Penelitian ini bertujuan untuk menghasilkan media pembelajaran berupa laboratorium virtual untuk kegiatan pembelajaran praktikum kimia. Responden yang dilibatkan dalam penelitian ini adalah mahasiswa jurusan teknik mesin, program studi teknik pendingin dan tata udara serta program studi teknologi rekayasa utilitas. Metode penelitian yang digunakan adalah metode penelitian dan pengembangan dengan model Lee & Owens, yang terdiri dari 4 tahap, yaitu: (1) Need Assessment/Analysis , (2) Instructional Design , (3)Pengembangan dan Implementasi , dan (4) Evaluasi . Analisis data menggunakan teknik analisis deskriptif kualitatif dan analisis statistik deskriptif. Berdasarkan analisis data terhadap hasil validasi isi dan media diperoleh nilai 89,13% dan 87,50%, yang dapat diinterpretasikan sangat valid atau tidak perlu dilakukan revisi terhadap produk yang dikembangkan. mahasiswa memberikan respon positif yakni 76,28%, terhadap implementasi laboratorium virtual sebagai media pembelajaran kimia.
