Abstract

Penelitian ini membahas pengaruh posisi jari pada fretboard gitar akustik terhadap frekuensi yang dihasilkan, dengan tujuan utama menentukan posisi jari optimal berdasarkan
hukum Mersenne. Metodologi penelitian melibatkan pengambilan data frekuensi dan panjang senar pada setiap titik pada fretboard, serta analisis tegangan senar menggunakan hukum Mersenne. Penelitian ini fokus pada variabel-variabel seperti panjang senar, tegangan pada senar, densitas senar, dan luas penampang senar yang berpotensi mempengaruhi frekuensi yang dihasilkan oleh senar gitar. Pengambilan data frekuensi dilakukan dengan menggunakanfretboard gitar yang memiliki titik-titik yang ditempatkan dengan jarak 0,5 cm satu sama lain. Setiap titik pada fretboard tersebut ditekan secara individual dengan melakukan 5 kali pengulangan. Data frekuensi kemudian direkam dalam bentuk rekaman suara, dan nilai frekuensi tiap iterasi setiap titik akan menjadi data untuk dirata-rata untuk diolah. Hasil penelitian menunjukkan bahwa semakin mendekati fret selanjutnya, frekuensi yang dihasilkan oleh senar semakin mendekati frekuensi ideal yang diinginkan. Selain itu, penelitian ini juga menunjukkan bahwa posisi jari pada fretboard berpengaruh pada panjang efektif senar, yang mengubah frekuensi yang dihasilkan. Penerapan hukum Mersenne dalam analisis tegangan senar memberikan pemahaman tentang hubungan antara tegangan senar dan frekuensi yang dihasilkan.

This study discusses the effect of finger position on the acoustic guitar fretboard on the frequency produced, with the main objective of determining the optimal finger position based on Mersenne's law. The research methodology includes data collection on frequency and string length at every point on the fretboard, as well as analysis of string tension using Mersenne's law. This study focuses on variables such as string length, string tension, string density, and string cross-sectional area which have the potential to affect the frequency produced by guitar strings. Frequency data collection is done by using a guitar fretboard which has dots placed 0.5 cm apart. Each point on the fretboard is pressed individually by doing 5 repetitions. The frequency data is then recorded in the form of a sound recording, and the frequency value for each iteration of each point will be the data to be averaged for processing. The results show that the closer to the next fret, the frequency produced by the strings is closer to the desired ideal frequency. In addition, this study also shows that the position of the fingers on the fretboard affects the effective length of the strings, which changes the frequency produced. The application of Mersenne's law in the analysis of string tension provides an understanding of the
relationship between string tension and the resulting frequency.
