Abstract

Optical Character Recognition merupakan sebuah teknologi yang digunakan untuk mengekstrak teks dari suatu objek atau gambar. Aplikasi Optical Character Recognition digunakan pada saat validasi surat ukur di kantor Badan Pertanahan Nasional Kabupaten Karangasem. Dimana proses validasi berkas perlu melakukan penyesuaian data dari data digital berupa hasil scan surat ukur kedalam data baru yang akan divalidasi. Aplikasi ini menggunakan bahasa pemrograman python yang terdiri dari fitur snip and copy untuk menangkap teks pada gambar, teks yang berhasil ditangkap bisa diedit atau langsung di paste pada tempat yang diinginkan. Aplikasi ini dapat meningkatkan efisiensi waktu dalam melakukan proses validasi surat ukur. Kata kunci : Optical Character Recognition , Python, Badan Pertanahan Nasional Kabupaten Karangasem.

Abstract

Negative Binomial Regression is a statistical modeling approach used to analyze count data with overdispersion, where the variance exceeds the mean. This study applies the method to examine the influence of weather factors on the daily number of cyclists crossing the Williamsburg Bridge in New York City. The independent variables used in the analysis include maximum temperature, minimum temperature, and precipitation. The dataset was obtained from the NYC Department of Transportation through the Kaggle platform and covers the period from April 1 to April 30, 2016. The analysis began with a Poisson Regression model; however, the presence of overdispersion was identified, indicated by a high AIC value of 8598.19, suggesting that the model was not suitable. The alternative Negative Binomial Regression model was then employed and produced a significantly lower AIC value of 518.77, demonstrating a superior fit. The findings indicate that maximum temperature has a positive effect on the number of cyclists, while precipitation shows a significant negative effect. Conversely, minimum temperature does not exhibit a meaningful influence. These results highlight the importance of considering weather conditions when planning bicycle-based transportation systems and support the development of sustainable mobility strategies in urban environments.

Abstract

Hepatitis is an inflammation of the liver which is often caused by a virus. Hepatitis that lasts less than 6 months is called "acute hepatitis", hepatitis that lasts more than 6 months is called "chronic hepatitis" Hepatitis consists of various types starting from hepatitis A, B, C, D and E. This study will discuss the classification Hepatitis C is classified as blood based (blood donor), suspected blood donor, fibrosis (moderate to severe hepatitis) and cirrhosis (chronic hepatitis). Classification uses the Support Vector Machines (SVM) algorithm with Confusional Matrix testing. The dataset used was obtained from the kaggle.com site with a total of 590 data consisting of 14 features or attributes. This study produces an accuracy of 93%
