Abstract

Dalam lingkungan bisnis modern, informasi dan data memiliki peran penting dalam pengambilan keputusan serta operasional perusahaan. Salah satu tantangan yang dihadapi adalah sinkronisasi data, terutama bagi perusahaan besar seperti PT XYZ, yang merupakan salah satu pemain terbesar industri ritel di Indonesia. Permasalahan muncul karena infrastruktur teknologi informasi mereka sedang dalam proses pergantian dan belum dapat sepenuhnya digantikan oleh yang lebih modern. Oleh karena itu, diperlukan proses sinkronisasi yang efektif untuk memungkinkan integrasi yang lancar antara perangkat lunak yang lama dan yang baru. Penelitian ini bertujuan untuk mengoptimalkan sinkronisasi data antara DBMS Oracle dan PostgreSQL dengan menggunakan Non-Cryptographic Hash Functions (NCHFs). Sebanyak tujuh NCHFs dievaluasi dalam eksperimen, dengan mempertimbangkan waktu eksekusi, penggunaan sumber daya, serta keberhasilan dan akurasi sinkronisasi. Hasil penelitian menunjukkan bahwa MetroHash secara konsisten memberikan kinerja terbaik. Dibandingkan dengan fungsi hash kriptografis standar seperti SHA-256, MetroHash berhasil mengoptimalkan waktu eksekusi hingga 29% lebih cepat. Ketika dibandingkan dengan NCHFs terbaik lainnya, seperti CityHash, MetroHash masih unggul dengan selisih waktu eksekusi sebesar 5%. Namun, pilihan penggunaannya harus disesuaikan dengan kebutuhan aplikasi dan situasi perusahaan. Selain MetroHash, CityHash juga merupakan alternatif yang layak dipertimbangkan. Di sisi lain, FNV-1a tidak disarankan karena kinerjanya yang kurang memuaskan.

Abstract

Indonesia is the biggest maritime country that has big marine resources too. It needed a good strategy so the marine resource usage can be managed well. Now, it can be helped by using information technology. The purpose of this research is to create a Geographic Information System for knowing potential marine resources in Daerah Istimewa Yogyakarta Coast. The result of this paper is a Geographic Information System that will runs in Android devices. The test results show 82,93% of users already satisfied with this application. It indicates that this application is in a Very Good category.

Abstract

PT XYZ is a retail company using Cloud Computing to support its business operations. The company requires the back-end application deployment process to be done automatically on each server computer. The problem occurs insecure in the process of the back-end application deployed manually causing human error vulnerabilities and inefficient when the version of application change occurs to operate on each server computer takes time as long as the number of server computers that need to be configured. The research aims to design a deployer system that help company to deploy back-end applications on each Ubuntu server computer automatically efficiently and securely. The research method uses Research and Development to create system. The research produces a design and build of an automated deployer system using Jenkins to create data configuration that aim the version of back-end application as target deploy and stored in the Cloud Firestore database. The stored data causing deployer system change version back-end application as stored data using GIT command and provide application to operate as service on each server computer. Operation result of application recorded as data deployment that stored in the Cloud Firestore then Jenkins detect it to store data as deployment log. Based on the results, the deployer system considered is able to operate back-end application automatically according the target version on each server computer as eficient and secure deployment process. This conclusion is supported by the results of the questionnaire, which obtained a 85% percentage and was classified as "Strongly Agree" with the created system.
