Abstract

One of the technologies that can be used as an attraction in Purbalingga Regency is Augmented Reality (AR) merging virtual objects with real objects, where those objects can be seen in real-time. And using the Location-Based Service (LBS) method, this method is a service with the main parameters being the position and location of the user. LBS Location Based Service will be enhanced with Google Maps and GPS (Global Positioning System) to find its user position and information about several locations to be visited. Virtual Reality (VR) brings users can interact in a virtual world environment simulated by a computer, so that users feel they are inside. The appearance of the Image object using 3600 panoramic so that it can display images indefinitely and not cut and can look around the image. Application creation is done by Multimedia Development Life Cycle (MDLC) and Unity3D. The application has been successfully operated on the Android operating system with minimum specifications of 2GB RAM and KitKat version 4.4 OS. The results of the study have been conducted through a questionnaire to 15 respondents with 15 questions earned an The total value of the frequency of each question gets a score of 1,009 or a percentage of eligibility of 89,68% starting that the application is well worth using. Based on the black-box test, the application has been running properly and can display Location Based Service and 3600 panoramic and its information.

Abstract

Purbalinga adalah salah satu kabupaten di Provinsi Jawa Tengah yang menarik untuk dikunjungi wisatawan. Potensi wisata dapat meningkatkan pendapatan dan memberi pengaruh penting dalam perkembangan daerah apalagi jika didukung oleh promosi yang menarik.  Salah satu teknologi yang dapat digunakan sebagai penarik minat adalah tersedianya Virtual Reality (VR) yang membawa pengguna dapat berinteraksi dalam lingkungan di dunia maya yang disimulasikan oleh komputer, sehingga pengguna merasa berada didalamnya. Penelitian ini melakukan perancangan dan implementasi aplikasi promosi obyek wisata Kabupaten Purbalingga menggunakan teknologi VR berbasis Android. Penampilan obyek gambar menggunakan panorama 360o sehingga mampu menampilkan gambar tanpa batas dan tidak terpotong serta dapat melihat sekeliling gambar. Pengguna membutuhkan VR Headset untuk menampilkan obyek secara virtual. Pembuatan aplikasi dilakukan dengan metode Multimedia Development Life Cycle (MDLC) dan Unity3D. Aplikasi telah berhasil dioperasikan pada Sistem Operasi Andorid dengan spesifikasi minimal RAM 2GB serta OS Versi 4.4 Kitkat. Hasil penelitian telah dilakukan pengujian melalui kuesioner kepada 10 responden dengan 11 pertanyaan didapatkan rata-rata skor 488 atau persentase kelayakan sebesar 88,72% yang menyatakan bahwa aplikasi sangat layak digunakan. Berdasarkan pengujian black box didapatkan bahwa aplikasi telah berjalan dengan baik dan dapat menampilkan 3600 panorama beserta informasinya.

Abstract

The hotel is a building that provides lodging services, restaurants, and other services that provide commercial for visitors. The use of hotel services that are still manual will be handled on the effectiveness of excellent service in hotel management. Computer technology support can be a solution in optimizing administrative activities, improving information, and making decisions. Hotel XYZ as one that still uses a manual transaction system. Then it is necessary to integrate data for each transaction using an interconnected database. Steps in the development of information systems need to be considered in improving the services of each hotel. The technique by collecting data to produce literature studies is an appropriate step to analyze the old system while developing the expected system. The results will be made on the design of the system for the database so that they are interconnected and the interface is easily understood by the user so that it facilitates the process of system implementation. After doing research, the black box test with a value of 100% with the results as expected is done. Comparison of the old system can be made by Microsoft Excel with interconnected databases presenting reports in printed form. It can meet the level of user satisfaction with a value of 95.3% of the results of the questionnaire from the five respondents involved.

Abstract

Data security is becoming increasingly crucial in information system management, especially in academic environments that handle sensitive information. The reliance on digital systems demands the protection of data integrity, confidentiality, and availability. High-level data security is also required in the Decision Support System (DSS) application for selecting Teaching Assistants at Universitas PGRI Yogyakarta. The DSS helps determine candidates based on GPA, experience, and skills. However, this system is vulnerable to threats such as unauthorized data modifications, access abuse, SQL Injection, and cyber-attacks that can impact decision-making. Stored Programs in databases provide an effective solution to enhance data security. This research aims to design Stored Programs as a security strategy for data input into database tables. The types of Stored Programs designed in this study include Stored Procedures, Functions, and control programs. The design methodology for the Stored Programs follows the waterfall method. The test results indicate that the Stored Programs function as expected and execute in a very short time. The execution of Stored Programs takes only 0.0059 seconds.

Abstract

Data security is increasingly crucial in managing information systems, especially in academic environments handling sensitive data. The reliance on digital systems demands protection of data integrity, confidentiality, and availability. Educational institutions must secure student, faculty, and administrative data to prevent unauthorized access and manipulation. One system requiring high security is the Decision Support System (DSS) for Teaching Assistant selection. DSS helps determine candidates based on GPA, experience, and skills. However, it is vulnerable to unauthorized data changes, access abuse, SQL Injection, and cyber threats that may affect decision accuracy. Stored Programs in databases provide an effective solution for enhancing data security. With Stored Procedures, Functions, Triggers, and Events, data management becomes more secure and structured. These features enable stricter access control, database operation automation, and direct validation to reduce errors and misuse. In the DSS case study, Stored Programs ensure that only authorized users can access and modify data. Authentication and authorization mechanisms restrict access based on user roles. This study analyzes security risks, system architecture design, Stored Program implementation, and its effectiveness in maintaining data integrity. Research results confirm that the developed Stored Programs meet expectations. The CRUD feature operates optimally with a processing time of 0.0059 seconds.
