Abstract

The digitalization of production data monitoring for rubber seedlings and plants is important for supporting effective cultivation processes and plantation management. However, the recording process at PT. Kendi Arindo is still performed manually, causing several problems, including reporting delays, data inaccuracies, and difficulties in archiving and reviewing production information. This study aims to develop an Android-based application for the digitalization of production data monitoring for rubber seedlings and plants to improve the efficiency, accuracy, and organization of field recording processes. The system development method used in this study is Design Thinking, which consists of the empathize, define, ideate, prototype, and test stages. This method was applied to understand user needs and design an application that addresses problems encountered in the field. The developed application enables officers to record, manage, and monitor production data quickly and systematically through Android devices. System testing was conducted using white-box testing to evaluate program logic and ensure that each function operated according to the designed specifications. The testing results showed that the application's main features functioned properly and met user requirements. The implementation results show that the application provides integrated features for recording, managing, validating, monitoring, and reporting production data. White-box testing showed that the program logic of the tested functions operated according to the system design. Therefore, the developed application provides a more structured and integrated system for managing production data and can be used as a digital medium for recording, monitoring, validating, and reporting production information at PT. Kendi Arindo.

Abstract

Digitalization of the employee information and attendance system is needed to support attendance management, which previously used a fingerprint machine. The existing system at PT Kendi Arindo still has several weaknesses, such as the potential for proxy attendance, delays in data recapitulation, and limited access to information for management. This study aims to develop an employee information and attendance system using a QR Code-based android application that integrates employee data management with centralized attendance recording. The study uses a qualitative approach with data collection techniques through observation, interviews, documentation, and literature review. The system development method used is design thinking, which consists of the empathize, define, ideate, prototype, and test stages. The application was developed using flutter and firebase with features for employee data management, QR Code generation and scanning, selfie and GPS verification, submission of leave, sick leave, and annual leave requests, request approval, and attendance reports. The system has three user access levels, namely HRD, management, and employees, with functions tailored to each role. Data management is carried out through centralized storage so that employee and attendance information can be managed, searched, and displayed in a more structured manner. The development results in an application that integrates employee information management and attendance into a single digital platform. The developed system is designed as an alternative to support the recording, management, monitoring, and reporting of attendance in a more structured manner at PT Kendi Arindo.

Abstract

The advancement of information technology encourages improvements in internet network management in educational environments. At SMK Negeri 3 Prabumulih, all users still use a single Wi-Fi password, which poses a risk of unauthorized access, suboptimal bandwidth management, and unequal internet access. This study aims to design a MikroTik Hotspot to support network security and equitable internet access. The research method used is the Network Development Life Cycle (NDLC), consisting of the Analysis, Design, Simulation Prototype, and Monitoring stages. The design includes user authentication through the Hotspot feature, bandwidth management, the addition of access points, restriction of administrator access based on MAC address, website blocking, and the implementation of client isolation. The test results showed that Hotspot authentication successfully provided access to users with the correct username and password. Bandwidth allocation operated according to the configured limits, with download and upload results of 4.83 Mbps and 4.81 Mbps, respectively, in the office, and 2.88 Mbps and 2.91 Mbps, respectively, in the TSM and TKR rooms. Testing of administrator access restrictions through Winbox using registered and unregistered MAC addresses showed that access could be restricted according to the configuration. Website blocking and client isolation testing also showed results consistent with the applied configuration. The proposed design can serve as a recommendation for the development of the internet network at SMK Negeri 3 Prabumulih.

Abstract

The management of medical records at Belida Darat Community Health Center is still carried out manually, resulting in several challenges, including slow healthcare services, difficulties in retrieving patient data, and the risk of data loss or damage. This study aims to develop an Android-based patient medical record application to improve the efficiency of healthcare service data management. The system was developed using the Rapid Application Development (RAD) method, which consists of requirements planning, user design, construction, and implementation stages. The research data were obtained through observation, interviews, and documentation, while the system functionality was evaluated using Black Box Testing. The results show that the developed application integrates patient registration, medical record management, examination data management, and report generation into a single Android-based system, making the data management process more effective and organized. In addition, the results of Black Box Testing indicate that all major system functions operate according to the predetermined functional requirements and are considered valid. Therefore, the developed application can be used to support medical record management and contribute to the digital transformation of healthcare services at Belida Darat Community Health Center.
