King Royal Hotel Restaurant still applies manual sales transaction recording, causing data management and revenue report preparation to be less than optimal. This study aims to design and implement a Flutter-based sales and revenue reporting application that utilizes local storage as a data storage mechanism on the device. The system development method used is the Waterfall method, which includes the stages of requirements analysis, design, implementation, testing, and maintenance. The application was developed using the Flutter framework with the Dart programming language and utilizes the shared_preferences and hive packages for local data management on the device without requiring an internet connection or external database server. In addition, the application is designed to be easy for restaurant employees to use in recording daily transactions more quickly and accurately. Testing was conducted using the Black Box Testing method, which showed that all application features functioned according to functional requirements. The results of the study indicate that the Flutter-based application with a local storage approach is capable of improving transaction recording efficiency and generating revenue reports automatically at King Royal Hotel Restaurant.

While TLS 1.3 is the latest standard, TLS 1.2 remains widely implemented in many cloud infrastructures. The selection of cipher suites in TLS 1.2, particularly between AES-128-GCM and AES-256-GCM, presents a trade-off between cryptographic strength and system performance. This research aims to analyze the performance comparison of these two algorithms on an Nginx server to determine the optimal configuration for cloud storage services. The study uses a quantitative experimental method by benchmarking two scenarios: (A) Strict (AES-256-GCM), and (B) Balanced (AES-128-GCM). Performance metrics measured include Requests Per Second (RPS), Latency, and Throughput. The results show that handshake performance (RPS and Latency) is nearly identical across all scenarios. However, in large file transfer tests, the AES-128-GCM algorithm (Scenario B) achieved a throughput of 32.4 MB/s, which is 12.5% faster than AES-256-GCM (28.8 MB/s). This study concludes that AES-128-GCM provides the best balance of security and efficiency for data-intensive environments.

In the modern computing era, servers face significant challenges in data storage due to hardware failures, cyber attacks, or human errors. The problem highlighted focuses on the impact of file systems on three critical aspects: data integrity (accuracy and consistency of data without corruption), data recovery (the ability to restore data after a failure), and failure resilience (fault tolerance, such as redundancy and journaling to prevent downtime). The main issue is that traditional file systems like FAT32 or NTFS are often susceptible to fragmentation, metadata loss, or long recovery times, which can lead to data loss of up to 20-30% on enterprise servers, especially in high-traffic environments like cloud computing.A simple problem-solving process is conducted through a straightforward comparative analysis approach: (1) A literature review of popular file systems (ext4, ZFS, Btrfs); (2) Failure simulations using tools like fsck and stress testing on virtual servers (e.g., via KVM or Docker); and (3) Measuring performance metrics with benchmarking tools like Bonnie++ for I/O throughput, recovery time, and error rates. This process is designed to be simple, requiring only a virtual lab setup without expensive hardware, and is analyzed quantitatively with descriptive statistics.The solution to the problem indicates that advanced file systems like ZFS or Btrfs provide significant improvements: data integrity is up to 95% more secure through automatic checksums, data recovery is achieved in minutes through snapshots and RAID integration, and failure resilience is higher with copy-on-write features. The main recommendation is to migrate to journaling-based file systems for servers, combined with automated backups, which can reduce the risk of downtime by up to 50%. This research provides practical guidance for system administrators to enhance server reliability without excessive additional costs.

This study aims to examine in depth the level of effectiveness and obstacles faced in the use of RME. This study uses a qualitative descriptive approach that aims to describe in depth the effectiveness and obstacles in the use of RME at the Baleendah Health Center. Data collection techniques were carried out through triangulation, namely, observation, interviews, and documentation. The informants in this study consisted of three people, namely the Head of the Puskesmas, medical records officer, and a doctor. Overall, the results showed that the implementation of RME at the Puskesmas received full support from the management, including aspects of funding, training, technology, and regular evaluation of the problems faced. RME has become the main focus because it is considered more effective and efficient than manual systems, especially in accelerating and improving the accuracy of services. However, the implementation still encountered a number of obstacles, such as internet network disruptions in the early stages, which have now been resolved by adding devices at certain points. The limited number of IT experts is also an obstacle because it slows down the handling of technical problems. In addition, server disruptions still occur because data storage is centralized at Diskominfo along with 62 other Puskesmas in Bandung Regency, which causes delays in data access.

Rapid developments in digital technology have increased the complexity of cybercrime and posed new challenges in its detection. Unlike traditional crimes, evidence in cyber cases relies on electronic evidence that has special characteristics, such as digital formats that are susceptible to change, storage on remote servers, and connections to aspects of digital forensics. The aim of this research is to analyze the evidentiary mechanism in cybercrime cases based on the Criminal Procedure Law (KUHAP), the Electronic Transaction Information Law (UU ITE) and other related laws and regulations. The research methodology used is normative law with case studies of legislative approaches and court decisions regarding the validity of electronic evidence. The study found that although electronic evidence is recognized as valid evidence in Indonesia's criminal justice system, obstacles to its implementation remain, including inconsistent legal interpretations, a lack of operational standards for digital forensic investigations, and limited human resources in law enforcement agencies. Therefore, to ensure the validity of evidence in cyber crimes, it is necessary to harmonize laws and regulations, increase the capacity of law enforcement officials, and strengthen cooperation between institutions.
