Abstrak: Batur sheep wool can be used as handicraft with high economic value. All this time, during the processing of turning wool into handicraft, syntetic color is still used. Syntetic color has side effects to both health and environment. The aim of this research was to study Batur sheep wool quality given natural dyes treatment. The measured variables consisted of water absorbance, dimensional stability, color intensity, and color fade resistance. Repetition was done 3 times to observe water absorbance, dimension stability, color intensity, and color fade resistance. Data were analyzed using T-test. Result showed that comparison between natural and synthetic dyes in water absorbance and shrinkage of Batur sheep wool were not significantly different (P>0.05). Color intensity showed that wool given natural dyes treatment appeared darker than wool given synthetic dyes. Color fade resistance of wool given yellow natural dyes is the best from the other

Abstrak: The wool of local sheep is still a by-product that can be used for some craft products. The aims of this research were to study the wool weight yield during the processing and to know quality of the wool yarn. Parameters were consisted of wool weight yield percentage during sorting I, washing, sorting II, carding and during spinning, and the quality of yarn, i.e, strength and elongation of the yarn. This research used the T-test analysis. There were 5 repetitions for observed wool weight yield during the process; 2 repetitions for strength and elongation of the wool yarn from garut sheep; and 5 repetitions for strength and elongation of the wool yarn from batur sheep. The results showed that percentage of wool weight yield from garut and batur sheep was not significantly different, except for the yield in spin stage that tended to be different. The yarn quality was statistically similar between two types of wool, but for the elongation they tended to be different. Sheep breed difference was not significant on wool weight yield and yarn quality. It is concluded that wool of garut sheep can be processed to make yarn, as same as wool of batur sheep.

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
