Abstract

In line with the growing use of computers in medicine, the perceived needs of the image data in digital format. The digital format allows for storage of image data in the computer and processes for further image analysis. Available images today are analog images, the necessary process of digitization with digitizer equipment.The image obtained is not necessarily as expected. Supporting equipment, film, and the scanner has a part in creating the image.Quality of image enhancement is needed to create a quality image allows physicians in diagnosing and minimize the possibility of error analysis.?One of the digital image processing techniques is improving the quality of the image (image enhancement). This is done to obtain a good image after a loss of quality during the process of digitizing the image. Image enhancement techniques are divided into two parts. They are spatial domain and frequency domain. This study uses the spatial domain technique which consists of two stages, such as point operation and mask operation. Image experiments performed with several samples such as thorak, collar bone, bone, body tissue, and the image of the hand. Some sample images have different characteristics but the process of image enhancement have in common that will be improving the image brightness.?Combining the methods of image enhancement performed to get the final digital image that has good qualities, such as histogram function,sharpen function, and continued with the function of a negative image.

Abstract

Magnetic Resonance Images (MRI) marupakan mesin terbaik dalam mendiagnosa tumor otak. Namun Interpretasi MRI membutuhkan waktu lama, dan sulitnya mendeteksi adanya edema. Edema adalah jaringan yang berada di dekat sel tumor aktif dan tumpang tindih dengan jaringan normal. Saat ini proses diagnosa citra MRI masih mengandalkan kemampuan pakar radiologi secara manual. Hal ini membutuhkan waktu lama, dan keputusan yang diambil dapat bersifat subjektif.  Sehingga dibutuhkan sistem yang mampu melakukan segmentasi citra MRI untuk membagi daerah-daerah citra menjadi beberapa bagian yang homogen. Pada makalah ini akan dijelaskan metode-metode segmentasi citra pada MRI tumor otak. Penjelasan akan dimulai dari pemahaman tumor otak, peralatan penghasil citra otak seperti MRI, dan metode-metode segmentasi yang pernah dilakukan peneliti sebelumnya. Metode pengklasteran dapat menjadi salah satu pendekatannya. Dan pengklasteran fuzzy merupakan metode yang unggul untuk segmentasi citra tumor otak. Kata kunci: MRI, segmentasi, tumor otak

Abstract

Indonesia is one of the countries that have many scattered areas. One of the issues of the many scattered areas is the development of underdeveloped areas. Scientific research can be used as a reference for increasing the development of an area based on the frequency of an area being the object of research by representing the data represented in maps and statistics. A histogram map will help in the process of analyzing areas and topics that are not covered by the research. The data collection technique used is distributed parallel web scraping to speed up the collection process from 46,280 regions in Indonesia. The system development method used is the SDLC (Software Development Life Cycle) waterfall starting from requirements analysis, system design, development, testing, and maintenance. The results are that the distributed scraping process generates data faster than running a single scraper. Scraping result data will be processed into maps and statistics that can assist researchers in interpreting and figuring out underdeveloped areas in Indonesia.

Abstract

Observing the great potential of the internet in rural environment, village government in Kragan, Gondangrejo District, Karanganyar Regency, has established internet network that residents could use with relatively lower price compared to that of other internet providers. Even though the internet connection has adequate speed, it still has obstacles specifically in managing the internet subscribers. Every villager who will subscribe to the internet must go to the village office and fill out a registration form and then the form is archived. Although the method is effective, it is vulnerable to customer data and information loss and is not flexible for residents who carry out their daily activities in a place that is relatively far from the village office. In addition, when there is an internet interruption, customers must send short messages to administrator, and then it will be inspected by a technician. Every reported problem is not stored properly, as a result, administrators cannot monitor whether customer complaints have been resolved. To overcome these two problems, a web-based application that is flexible and can be used by users with various computer platforms is proposed. The application development follows the waterfall model. The results of testing using black-box technique show that the functionality of the application is running with a failure percentage of 0%. Meanwhile, the test to determine usability level of the application using the System Usability Scale (SUS) method showed an acceptance rate of 66,2%, meaning that the application is suitable for use even though training for the users is needed.

Abstract

Penggunaan teknologi pada era globalisasi saat ini telah membentuk ruang kehidupan baru sehingga menyebabkaan peningkatan pengguna aktif internet. Internet selain menghadirkan kemudahan bagi penggunanya, juga memberikan dampak negatif yang cukup berbahaya. Tingginya angka pengguna aktif internet seharusnya dibarengi dengan tingkat keamanan cyber yang tinggi. Akan tetapi, pada prakteknya kondisi keamanan cyber di Indonesia masih tergolong lemah. Menurut Pusat Operasi Keamanan Siber Nasional (Pusopskasinas), Badan Siber dan Sandi Negara (BSSN) mencatat hampir 1 milyar serangan cyber telah terjadi sejak januari hingga desember 2022. Oleh karena itu, untuk mengetahui kualiatas keamanan dan pentingnya fungsi serta performa yang ada pada website pengelolaan internet di Desa Kragan, maka perlu diterapkan pengujian keamanan (penetration testing). Pengujian menggunakan metode Penetration Testing Execution Standard (PTES) yang merupakan panduan metodologi tentang apa yang diperlukan untuk uji penetrasi yang efektif. Hasil yang didapat setelah uji penetrasi testing yaitu terdapat 14 celah keamanan dimana 3 celah diantaranya menjadi bahan untuk di eksploitasi. Ketiga celah keamanan tersebut yaitu SQL injection, Absence of Anti-CSRF Tokens, dan Missing Anti-clickjacking Header. Hasil SQL injection tidak dapat dilakukan karena website telah menggunakan Secure Socket Layer (SSL) untuk mendukung keamanan website, sedangkan hasil 2 eksploitasi lainnya adalah bahwa celah keamanan tersebut berhasil dieksploitasi dan dapat menjadi ancaman cyber apabila tidak segera diperbaiki.
