Abstract

Ruang kelas merupakan tempat diadakannya proses belajar mengajar. Dalam ruang kelas terdapat berbagai macam fasilitas pendukung proses belajar mengajar. Kerusakan fasiltas yang ada diruang kelas akan mengganggu proses belajar mengajar. Kerusakan fasilitas ruang kelas tersebut antara lain infocus rusa, ac mati, kabel rusak dan lain sebagainya. Kerusakan kerusakan tersebut karena sering pakai oleh mahasiswa dan dosen secara bergantian sehingga kalau terjadi kerusakan akan mengganggu mahasiswa dan dosen lain yang akan mengajar berikutnya. Untuk melaporkan kerusakan ruang kelas tersebut agak susah karena sebagian besar mahasiswa dan dosen tidak tahu pihak yang berwenang untuk menangani kerusakan fasilitas ruang kelas tersebut. Masalah tersebut perlu dicarikan solusinya agar kerusakan dapat terselesaikan dengan cepat dan tidak mengganggu mahsiswa dan dosen lain yang akan menggunakan ruang kelas tersebut. Solusi dari permasalahan tersebut dengan cara mengembangkan aplikasi berbasis android untuk melaporkan setiap kerusakan fasilitas yang ada diruang kelas. Penelitian ini akan mengembangkan sistem untuk mengatasi permasalahan tersebut.

Abstract

Variants of covid in Indonesia continue to grow and make people required to stay at home and are not required to go out if they don't have important things, therefore many people who stay at home often play social media such as twitter, it is possible that many irresponsible people make opinions or hoaxes with a specific purpose to make tweets that are not in accordance with the facts, which are feared to make the public more panicked about the increase in this covid-19 variant. Therefore this study was conducted to classify tweets as positive, negative, and neutral. The methodology used is a text mining process with 4 modelings using Support Vector Machine and Particle Swarm Optimization. The results obtained from the 4th modeling produce an accuracy of 83% on the linear kernel. While the PSO modeling in scenario 4 with 90:10 data division resulted in the highest accuracy in linear and polynomial kernels of 86% and 87%, respectively. Other evaluation values ​​also improved, such as precision to 90%, recall to 83%, and f1-score to 86%.
