IMPLEMENTASI QUICK RESPONSE (QR) CODE PADA APLIKASI PRATINJAU KONTEN KOMIK CETAK

Indonesia menduduki peringkat kedua di dunia untuk jumlah pembaca komik dengan nilai rata-rata seseorang membaca 3,11 buku komik, atau sekitar 3 buku per orang. Indonesia berada di bawah Finlandia sebagai pembaca komik terbanyak dengan jumlah rata-rata satu orang membaca hampir empat buku komik. Dibalik tingginya jumlah pembaca komik di Indonesia, ada masalah pada komik baru. Calon pembaca ingin tahu seperti apa konten yang tersaji di dalam komik yang akan dibaca, tetapi tidak bisa melihat-lihat isi komik atau meninjau terlebih dahulu isi komik yang masih baru karena komik tersebut selalu disegel atau dibungkus dengan plastik. Apabila calon pembaca membuka segel komik tersebut, maka komik itu harus dibeli. Tujuan penelitian ini menyediakan fasilitas dalam mengelola konten pratinjau komik dan memudahkan calon pembaca untuk mengakses pratinjau dengan implementasi QR code. Hasil dari penelitian ini yaitu calon pembaca dapat mengakses pratinjau komik dengan memindai QR Code pada komik, kemudian path URL muncul dan mengarahkan calon pembaca ke halaman pratinjau komik secara online

Stateless Authentication with JSON Web Tokens using RSA-512 Algorithm

Today's technology needs are getting higher, one of the technologies that continues to grow now is Web Service (WS). WS can increase service flexibility on a system. However, security at WS is one of the things that needs attention. One effort to overcome this problem is JWT (JSON Web Token). JWT is one of the authentication mechanisms in WS, with a standard signature algorithm, HMAC SHA256, RSA-256 or ECDSA. In this research we will discuss the performance of JWT RSA-512 which is implemented on SOAP and RESTful. Because based on previous research the speed performance of the 512-bit algorithm is better, but it is not yet known if applied to JWT. The test results show that the speed of the JWT RSA-512 token on the RESTful process is superior to 24.69% compared to SOAP. Then the speed of the authentication of JWT RSA-512 tokens, RESTful is superior to 11.64% compared to SOAP. Whereas in testing the size of JWT RSA-512 generated tokens, RESTful is only 1.25% superior to SOAP.Today's technology needs are getting higher, one of the technologies that continues to grow now is Web Service (WS).

Application of the Finite State Machine Algorithm on 2D Platformer Rabbit Games vs Zombies

This research develops Android games by applying the FSM Algorithm (Finite State Machine) for the movement of NPC (Non-Player Character) to produce dynamic movements. The popular and legendary game with the appearance of side scroller is Super Mario Bross and Shovel Knight, the game is the most preferred game of its time to the present, but the game does not apply AI (Artificial Intelligence) so the game seems less challenging. The game is a concept game that is currently rarely used. Based on this, a side scroller-based survival game was created by implementing AI on NPCs on the Android platform. The AI used is the FSM Algorithm which functions to regulate enemy movements. The method used in developing multimedia products of this game uses MDLC (Multimedia Development Life Cycle). Based on the tests that have been carried out, the alpha test results are functionally appropriate and the results of beta testing using UserAcceptence Test (UAT) obtained a value of 86.40% which is declared feasible to use and can be developed. The advantages of this game are the presence of shock elements in the form of landslides, bursts of water, rock rain, and attacks by eagle

Designing UI/UX For SDN 1 Sukamulya Ciamis Website Using the Five Planes and WEBUSE Methodologies

The web-based information world is currently experiencing rapid growth, encompassing interactive, dynamic, and static elements, with educational institutions being one of its prominent users. It provides swift and precise information services, contributing significantly to the fundamental development of the education sector. The school profile website from the Ministry of Education and Culture (KEMENDIKBUD) currently only provides basic profile features. Due to the lack of information and features on the website, a redesign and further development are necessary. Therefore, this research, based on interviews with relevant parties such as SDN 1 Sukamulya, calls for a redesign and development of the website. The approach taken in this redesign and development utilizes the Five Plans method. The creation of a website that aligns with user preferences, combines an attractive design, and offers an experience that meets user needs. The design and development of this website will be evaluated using the WEBUSE method. WEBUSE (Web Usability Evaluation) is a method for assessing the extent of usability based on a comprehensive usability criteria questionnaire. In the UI/UX design phase, the Five Planes method was applied, and after the design phase, the website's feasibility was assessed using the WEBUSE method. This research successfully designed a website for SDN 1 Sukamulya by applying the Five Planes method in the design process. Based on the comparison of evaluations using the WEBUSE method, the usability score of the website improved from a usability score of 0.657, falling into the "good" range (0.6 - 0.8), to a usability score of 0.829, falling into the "excellent" range (0.8 - 1). This score indicates that the website's usability level is excellent, demonstrating that the design and development efforts have successfully provided an outstanding user experience
