Abstrak: Sheep is the one of many leather product. Mostly, leather of sheep have size more small and thin than cow and buffalo. Leather of cow and buffalo can make the leather light. The observation consists of experiment using six sheets of sheep leather, respectively. The observation design used on experiment has Direct Randomized Complete Design with three repeatations. Variable analysis of experiment consists of tensile strength and elongation of leather, and torn strength. The experiment result showed that tensile strength value of chrome tanned leather of Javanese fat-tailed and local Javanese thin-tailed not clear different were respectively 42.86 ± 2,12 kg/cm3 ; 38.56 ± 2,16 kg/cm3. The elongation value of chrome tanned leather of Javanese fat-tailed and local Javanese thin-tailed not clear different were respectively 99.25 ± 36,59 % ; 104.03 ± 21,71 %, whereas the torn strength given were respectively 3.57 ± 0.9194 kg/cm3 ; 3.475 ± 0.2947 kg/cm3. The tensile strength, elongation, and torn strength value of chrome tanned leather of Javanese fat-tailed were not clear different than leather of local Javanese thin-tailed.

Abstrak: Tanning is the process of converting protein rawhide into leather which stable and not easily decompose. Tanning can be performed on the skin of chicken claw because it has a protein content that is not different from the protein skin of cattle about 23%. The use of chromium can be overcome with vegetable tanning materials that derived from plants and environmentally friendly. The purpose of this study was to determine the characteristics of the tanned skin of chicken claw with a combination of chrome, mimosa and guava leaf extract. Observed variables consisted of tensile strength, elongation, and tear endurance with repetition performed 3 times. The results showed that the concentration of guava leaf extract different effect on tensile strength, but has no effect on elongation and tear endurance of leather. Chrome and mimosa still give effect to the tanning process, but the addition of guava leaf extract as much as 10% showed optimum ability to help increase the tensile endurance of leather.

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%.
