Abstract

Today’s most common Positioning System applied is the Global Positioning System (GPS). Positioning System is considered accurate when outdoors, but it becomes a problem when indoors making it difficult to read the GPS signal. Many academics are actively working on indoor positioning solutions to address GPS's drawbacks. Because WiFi Access Point signals are frequently employed in multiple studies, they are used as research material. This study compares the classification algorithms KNN, SVM, Random Forest, and C 4.5 to see which algorithm provides more accurate calculations. The fingerprinting method was employed in the process of collecting signal strength data in each room of the Terpadu Laboratory Building at UIN Sunan Kalijaga using 30 rooms and a total dataset of 5,977 data. The data is utilized to run experiments to determine the location using various methods. According to the experimental data, the Random Forest algorithm achieves an accuracy rate of 83%, C4.5 81%, and KNN 80%, while the SVM method achieves the lowest accuracy rate of 57%.

Abstract

The food security, fisheries and agriculture services work with local government to help the community. In carrying out its work, the government applies information technology to achieve the goals. Therefore, it is necessary to have an IT governance design to ensure the alignment of the government’s objectives and the use of IT. Governance is an important asset to measure the effectiveness and efficiency of work process improvement using IT. This research is conducted because there has never been an IT governance design assessment. The analysis and design of IT governance at government agencies are carried out using the COBIT 2019 framework to measure the level of IT capability. The research method used is descriptive qualitative by conducting interviews with influential government parties. This study obtained an IT governance design and detected important processes for the domains used, namely EDM04, APO04, APO07, APO08, APO11, BAI03, BAI08, BAI10.
