Abstract

A house is a building that functions as a residence or residence and a means of fostering a family. In rural areas there are still many residents' houses that are uninhabitable and this is caused by the standard of living of people who still live modestly and have incomes below the average, these conditions make many residents' houses uninhabitable that need to be renovated through house renovation assistance. Decision making is a system that is able to provide both problem-solving abilities and communication skills for semi-structured problems. This research system aims to design a system for determining recipients of home surgery assistance using the method, Weighted product which is one of the methods in SPK which uses a weighting method with a rating of an appraisal variable. The programming language used in making the system is PHP with a MySQL database. The results of the implementation of the system that has been made show that Parasman (A1), Hendra (A9), Ferdinand (A4) are candidates for receiving surgical assistance in Siantar Narumonda District.

Abstract

This research discusses the creation of a website and Field Person application designed to assist the management of construction project data processing. This system allows company leaders to monitor projects in real-time and assist field heads in compiling work reports. The main functions implemented include material management, shopping data, equipment data, work progress data, incoming funds, material usage, material requests, wage requests, and wage payments. This research uses an object-oriented software development methodology with an Agile approach to ensure flexibility and responsiveness to changing user needs, and offers innovative solutions in construction project management by utilizing technology to improve efficiency and accuracy in project data management.

Abstract

The digital transformation of lecturer performance evaluation systems in higher education has improved efficiency in data collection and reporting; however, system effectiveness depends significantly on its usability. A system that is difficult to use may reduce student participation and compromise the quality of evaluation data. This study aims to evaluate the usability level of an online lecturer performance assessment questionnaire system using the System Usability Scale (SUS). The research employed a descriptive quantitative approach involving 30 active students as respondents who had completed the online questionnaire. Data were collected using a 10-item SUS instrument with a five-point Likert scale and analyzed according to standard SUS scoring procedures, followed by descriptive interpretation and validity testing using Pearson correlation. The results showed that the average SUS score was 49.75, which falls into the “Poor” category, indicating that the system’s usability level has not yet reached an acceptable standard. Although the system is generally accessible and relatively easy to learn, several aspects—particularly navigation clarity, interface consistency, and user feedback mechanisms—require improvement. The validity test confirmed that all questionnaire items were statistically valid. These findings imply that systematic redesign and iterative usability evaluation are necessary to enhance user experience, increase student participation, and strengthen the effectiveness of lecturer performance evaluation as part of sustainable academic quality assurance in higher education institutions.
