One of the junior high schools in West Sumba is SMP N 5 Loli. The study period here lasts for 3 years, like other schools in Indonesia. Based on findings from interviews conducted at SMPN 5 Loli, alumni tracing will be done by sending letters to students to answer questions with their signatures. Tracking or tracing alumni is one of the methods used by some schools in Indonesia to get answers from their graduates. The answers obtained from the graduates are very important for the school in their efforts to improve and enhance the quality and education system. Therefore, an internet-based system will be developed that allows alumni to access information via the internet using mobile phones, gadgets, laptops, or other devices according to their wishes and needs. The system also has the ability to store existing alumni search data and automatically generate reports containing the percentage of alumni responses so that administrators can compile alumni search reports without having to re-enter or move the search data to another system. The method used by the author in modeling this system is waterfall. Waterfall is one of the simple system development methods consisting of 5 stages: software requirements analysis, system design, system implementation, testing, and maintenance. The system testing used in the research on modeling this system is Black Box. Based on the research results and discussion, it can be concluded that this research produces a model of the alumni tracer study system and the system can display alumni data based on the year of the alumni batch.

The Final Project is an official work that consists of a thesis or an artwork, which is the result of research or scientific creation by students, conducted through a series of steps and procedures in accordance with the Final Project (TA) guidelines set by each faculty. One strategy to encourage students to complete their studies as quickly as possible is to require students who are working on their Final Project (TA) to attend campus at least once a week to report on their progress while bringing their Final Project guidance card. Interviews are conducted with students to find a supervising lecturer, students hold proposal guidance, after which the proposal is validated, students then register for the proposal seminar, students conduct the proposal seminar, a decree (SK) is issued, students continue with Final Project guidance, the documentation of the Final Project is validated, students register for the results seminar and final defense, as well as students undergoing plagiarism checks. This is due to the lack of application platforms that can monitor students' completion of their final projects online. Therefore, research on an information system application to supervise students' final projects is very much needed.

Wewewa Timur District is an administrative area in Southwest Sumba Regency that has great potential to improve the quality of public services. However, in practice, services at the sub-district level are still faced with various obstacles, such as slow administrative processes, manual data recording, and lack of coordination between service departments. This makes it difficult for government officials to cause problems and has a direct impact on public satisfaction as service recipients. As a solution, the development of a Web-Based Integrated Service Information System is the right step to address community needs and support government performance in Wewewa Timur District. Through this system, the public can access various services on a single digital platform without having to come directly to the sub-district office, and helps officials in accelerating administrative processes. This study uses a software engineering approach to design and implement a Web-Based Integrated Service Information System in Wewewa Timur District. The method used is the Waterfall method, which is a classic method in software engineering with sequential and systematic stages, from needs analysis to system maintenance. Test results using the black box method showed that the software could identify malfunctioning functions, interface errors, data structure errors, and access to external databases, while also producing expected output. Therefore, this system is considered effective in improving the quality of public services in Wewewa Timur District.

This study aims to evaluate the quality of public services at the Department of Population and Civil Registration of West Sumba Regency following the implementation of digitalization through the use of electronic signatures. A quantitative approach was employed, with data collected through questionnaires distributed to 100 respondents. Data analysis was conducted using the Importance Performance Analysis (IPA) method to identify gaps between the level of importance and service performance. The results indicate that, overall, service quality can be categorized as fairly good, as reflected by performance levels that are relatively close to public expectations. However, several service attributes remain in the priority quadrant, particularly in terms of system usability, service stability, and accessibility. Meanwhile, attributes such as service speed, data security, and staff responsiveness demonstrate satisfactory performance and should be maintained. These findings suggest that the implementation of electronic signatures has improved service efficiency and effectiveness, although further improvements are still required, particularly in technical aspects and system usability. Therefore, continuous improvement efforts are necessary to enhance public service quality, making it more responsive and oriented toward user satisfaction.
