Abstract

BPS West Sumba Regency still manages mail manually, facing issues of efficiency, transparency and accuracy. Manual processes risk document loss and recording errors. This research aims to identify problems and recommend an integrated information system. This innovation is expected to increase productivity, reduce errors, and speed up decision-making at BPS. Rapid Application Development (RAD) is a software development model that focuses on accelerating processing time. This approach combines object-oriented development methods and structured techniques to accelerate the process of creating a system or application. The research showed that the implementation of the new information system at BPS West Sumba Regency improved operational efficiency. Mail processing time dropped from 3 hours to 1 hour, and the error rate was reduced from 15% to 2%. User satisfaction increased from 60% to 90%, which had a positive impact on employee motivation. User satisfaction increased from 60% to 90%, which had a positive impact on employee motivation and collaboration. The system also strengthened and improved transparency.

Abstract

The nutritional status of toddlers is an important indicator in assessing the health of a community, especially during the growth period of childhood. Nutritional problems that are not handled properly can have an impact on the physical and cognitive development of toddlers. Therefore, a method is needed that can help health workers classify the nutritional status of toddlers quickly and accurately. This study aims to apply the C.45 algorithm in classifying the nutritional status of toddlers at the Wairasa Health Center. The data used in this study included the age of toddlers, weight, and height, with the output class in the form of nutritional status of toddlers consisting of good nutrition, poor nutrition, and severe malnutrition. The research methods used included data collection, pre-processing of data, application of the C.45 algorithm, formation of a decision tree, and evaluation of the model using a matrix of confusion and accuracy values. The results of the study showed that the C.45 algorithm was able to produce decision trees and classification rules that were easy to understand and had a fairly good level of accuracy in classifying the nutritional status of toddlers. Thus, the application of the C.45 algorithm can be used as a decision support tool for health center staff in determining the nutritional status of toddlers objectively and efficiently.

Abstract

This research aims to design and implement a web-based personnel information system for the West Sumba Regency Education, Youth and Sports Service (DPKO) using the Laravel framework. This system is designed to make it easier to manage personnel data which includes employee data, attendance, payroll and various other personnel-related information. By utilizing the Laravel framework, this system is expected to be able to provide convenience in managing data efficiently, structured and securely. The use of Laravel was chosen because of its advantages in developing web applications that are fast, safe, and supported by complete features. The results of this research show that the personnel information system being developed can speed up the process of processing employee data, reduce errors in data input, and provide convenience in making data-based decisions. Evaluation of this system was carried out through functionality and performance testing, which showed that this system worked well in accordance with the needs of the West Sumba Regency DPKO.

Abstract

This research aims to design and implement a web-based administrative service information system at the West Umbu Ratu Nggay District Office using the Waterfall method. This information system was developed to increase efficiency and effectiveness in managing administrative services, such as writing letters, archiving documents and other administrative processes which often take a long time if done manually. By applying the Waterfall method, system development is carried out in stages, starting from requirements analysis, design, implementation, testing, to maintenance. This method was chosen because of its ability to ensure that each stage of system development is carried out in a structured and detailed manner. The research results show that the information system developed is able to automate various administrative processes at the Umbu Ratu Nggay Barat District Office, making it easier for employees to carry out their duties and improving the quality of service to the community. Evaluation of this system was carried out through functional testing and user trials, which showed that the system functions well and meets the administrative needs of the sub-district office.
