Abstract

PT XYZ is an agri-food company that has used the information technology for its company's operations. Information technology management at PT XYZ requires an audit to determine the level of information technology capability on PT XYZ and it provides a recommendations for business process improvements to achieve the business objectives of the company. Since this audit is intended to assess the managerial and technical aspect of information technology, audit of PT XYZ is conducted by applying COBIT 5 framework. Procedure of COBIT 5 consists of audit plans, audit preparation phase, the implementation phase of the audit, and audit reporting stage. This audit measures the capability level of information technology management at the sub-domain Manage Strategy (APO02) Manage Enterprise Architecture (APO03) Manage Relationships (APO08) Manage Suppliers (APO10) Manage Requirements Definition (BAI02) Identification Solutions Manage and Build (BAI03), and Manage Knowledge (BAI08). Based on evaluation using COBIT 5, PT XYZ is in the level 2.6 out of 5. Due to the rounding index value, the measurement results are at level 3 (Established Process) while the company's expectation level is at level 5. The level difference occurs because PT XYZ has not conducted a review, evaluation, and report of the settlement. Therefore, companies need to improve information technology management in achieving the company's business goals.

Abstract

one of Indonesia's cultures on October 2, 2009. Lampung initially did not have a batik tradition but there is a legacy that is referred to as the first batik worn by Lampung people, namely sembagi cloth. Batik Siger is a business that produces batik typical of Lampung which originated from a course and training institution and was established in 2008. LKP Batik Siger provides services to the community in the field of written batik. This research discusses the performance of backpropagation and convolutional neural networks that will be used for the classification of Lampung batik image patterns. The Lampung batik motifs used are sembagi, pakjimo, granitan, soga, siger tangkup betik, jung agung, kembang cengkih and siger ratu agung. The stages that will be carried out are scaling, grayscale, thresholding and classification. The comparison of training data, testing data and validation used is 70:20:10 with the needs of backpropagation and convolutional neural network, namely epoch = 100, learning rate = 0.01. Backpropagation classification resulted in an accuracy of 96.25% and a classification error of 3.75%. The convolutional neural network classification resulted in an accuracy of 99.37% and a classification error of 0.63%. The performance of the CNN method has 3.12% higher accuracy compared to the performance of convolutional neural network.
