Abstract

Campus is a place which is teaching and learning process occur. One factor that support a good learning environment is to avoid noise problems. The object of the research is the campus of Semarang University located on Jalan Arteri Soekarno-Hatta, it is located on the edge of the Kaligawe-Gayamsari toll road. Both roads includes the most crowded transportation routes in Semarang City.Campus area requires a quiet and silent environment. It is difficult for the urban areas to get a quiet campus environment. The study tries to reveal the evaluation on how the noise factors that occur during teaching and learning process. The study was conducted at Semarang University. The research method used is descriptive analytic method. The research was conducted by measuring the noise level using Sound Level Meter (KRISBOW) type KW08-291, several data collection points was taken at Semarang University, both open and closed environments around campus. The results of noise measurements would be carried out in noise mapping to know the noise distribution map in the campus area. The noise level in the campus is still above 55 dB on average. It shows that the noise level in the environment of Semarang University has not been in line with the predetermined standard that is still greater than (40 - 50 dBA) in accordance to the decree of the State Minister of the Environment number 48 of 1996.Keywords: noise, sound level meter, noise threshold value, decree of the State Minister of the Environment number 48 of 1996

Abstract

Perkembangan ilmu pengetahuan dan teknologi yang semakin maju telah menghasilkan berbagai macam peralatan canggih yang dapat menunjang terpenuhinya kebutuhan hidup. Oleh sebab itu diperlukan generasi penerus yang pandai dan kreatif. Hal ini yang menyebabkan kebutuhan pendidikan yang semakin tinggi dan permasalahannya semakin kompleks. Pembelajaran tentang gelombang sudah didapatkan sejak duduk di bangku SMP, tetapi pemahaman tentang hal ini masih kurang. Oleh karena itu, dengan memanfaatkan fasilitas-fasilitas yang diberikan komputer, perumusanperumusan gelombang elektromagnetik yang abstrak akan lebih mudah dipahami. Visualisasi dari grafiknya dapat memberikan kemudahan bagi mahasiswa untuk lebih memahami materi yang diberikan. Penelitian ini dilaksanakan dalam dua tahapan, tahapan yang pertama dimulai dari studi pustaka pendukung terutama yang berkaitan dengan superposisi gelombang. Langkah selanjutnya adalah menurunkan rumusan superposisi dua gelombang dengan variasi frekuensi, amplitudo, dan fase yang berbeda-beda. Tahapan kedua yang dilakukan hampir sama dengan tahapan pertama yaitu studi pustaka, namun cukup dengan memperoleh fungsi gelombang tunggal. Selanjutnya berdasarkan fungsi gelombang dengan variasi frekuensi, amplitudo, dan fase. Proses superposisi gelombang dilakukan dengan cara menjumlahkan data sintetik fungsi gelombang 1 dan 2, menghasilkan data sintetik fungsi gelombang hasil superposisi. Data sintetik ini kemudian divisualisasikan dalam bentuk grafik Penelitian ini menghasilkan visualisasi konsep perlayangan gelombang yang diungkapkan dalam grafik hubungan antara simpangan terhadap waktu dengan frekuensi berbeda, amplitudo dan beda fase yang berbeda. Kata kunci : perlayangan gelombang, superposisi, spreadsheet

Abstract

Optimal teaching or learning activities require a conducive and quiet environment because the high concentration required on its’ process. Campus area requires a quiet and silent environment. It is difficult for the urban areas to get a quiet campus environment. The study tries to reveal the evaluation on how the noise factors that occur during teaching and learning process. The study was conducted at Semarang University. The research method used is descriptive analytic method. Research shows that the building of engineering faculty (the A building) at Semarang University shows the proper noise level in line with the standard (School Acoustic Quality Standards). Besides, Semarang University must establish rules and policies to control the noise levels, to intensify the comfort of the lecture process. Based on the research results, the noise level on the Engineering faculty building of Semarang University has not been in line with the predetermined standard, which is more than (55 dB).Keywords: noise, lecture activities, acoustic quality standards of school buildings
