Abstract

The implementation of the service of making E-KTP (Electronic Identity Card) in some areas has problems such as data filling, fingerprint recording, retina, photo taking, the reason for blank E-KTP blanks and the bureaucratic structure of E-KTP publishing is often problematic because of the server system . Government agencies in the Pagar Merbau District Head Office do not know specifically the level of community satisfaction in managing the E-KTP. SPK application is used in decision making. The SPK application uses a flexible, interactive, and adaptable CBIS (Computer Based Information System) developed to support solutions to specific, unstructured management problems. The Analytical Hierarchy Process (AHP) method is a method of decision making in solving multicriteria problems. From the AHP calculation, the final result is obtained with the condition that if the value is ≥ 0.4, then the information is Satisfactory Service if 0.4, then the information is Poor Service.

Abstract

Daun srilanka dikenal dengan nama daun sirsak, berbentuk bulat lonjong. Identifikasi citra berdasarkan tepi (outline) objek dalam Pengolahan citra menggunakan edge detection. Operasi pelacakan tepi untuk menemukan perubahan intensitas lokal yang berbeda dalam sebuah citra. Penerapan Sobel dan Prewitt adalah untuk mengurangi noise sebelum melakukan perhitungan deteksi tepi sehingga tepi-tepi yang dihasilkan lebih banyak. Deteksi Tepi Sobel dan prewitt dapat mendeteksi tepian yang sebenarnya dengan tingkat error yang minimum. Sobel dan Prewitt mampu mengidentifikasi tepi dengan sumbu-sumbu yang digunakan, memiliki intensitas bilangan acak yang hasilnya berupa angka 0 dan 255 secara menyebar. Sistem yang dibangun menampilkan konversi citra RGB, Grayscale, Sobel dan Prewitt dan Histogram dari proses citra yang dilakukan. Hasil analisa metode Sobel dan Prewitt ditampikan dalam grafik histogram.

Abstract

The movement of the eye ball affects the condition of the pupil to dilate to become smaller or vice versa, it indicates a person's mood changes very quickly. The image of the eyeball is not necessarily in accordance with the condition of a person's heart, so it is necessary to analyze the movement of the pupil of the eye. Facial expression using the Hough Transformation Method focuses on the movement of the pupil of the eye. The Hough transform works by looking for the neighbor relationship between pixels using straight line equations to detect lines and circular equations to detect circles. Hough line transform is a technique most commonly used to detect curved objects such as lines, circles, ellipses and parabolas. The detection accuracy of the pupil is influenced by the accuracy of the extraction of the edges of the eye. If the outer circle identification is not detected, Hough Transform will be identified. The segmentation step carried out can identify the pupil circle region with a detection success of 80-85%.

Abstract

Data security and confidentiality is currently a very important issue and continues to grow. Several cases concerning data security are now a job that requires handling and security costs that are so large. To maintain the security and confidentiality of messages, data, or information so that no one can read or understand it, except for the rightful recipients, a data security system application with an encryption method using an algorithm is designed. The SHA-1 cryptographic hash function that takes input and produces a 160-bit hash value which is known as the message iteration is usually rendered as a 40-digit long hexadecimal number.
