Mochamad Rafif Rabbani, 26050117170001, Analisis Hubungan Environmental
Sound Noise (ESN) Terhadap Kondisi Kondisi Gelombang Permukaan Di Selat
Lombok, Nusa Tenggara Barat (Prof. Dr. Denny Nugroho Sugianto dan Teguh
Arif Pianto)
Perairan Selat Lombok merupakan salah satu perairan di Indonesia yang memiliki
manfaat yang penting bagi masyarakat sekitar dan faktor alamnya yang kompleks
seperti Oseanografi, misalnya terkait dengan noise. Akustik Tomografi Pantai
menjadi salah satu teknologi mampu merekam gangguan berupa gangguan
lingkungan sekitar atau noise telah dipasang pada 3 lokasi di Perairan Selat Lombok
dengan keluaran data berupa data RAW (Read After Write) dan ESN
(Environmental Sound Noise). Data ESN digunakan untuk melakukan monitoring
terhadap kondisi lingkungan di sekitar tranduser dengan hanya melakukan proses
receive tanpa adanya proses transmit dari stasiun pasangan akustik tomografi yang
kemudian dikonversikan menggunakan MATLAB dengan satuan std ESN (Standar
Deviasi ESN). Perbandingan nilai ESN dilakukan untuk mengamati bentuk
lingkungan di sekitar alat tranduser dipasang dengan menggunakan 3 Variabel
pembanding, yaitu, Kecepatan Angin, Curah Hujan, dan Tinggi Gelombang
Signifikan. Pengolahan dilakukan dengan menggunakan analisis regresi polinomial
dan Principal Components Analysis. Hasil menunjukkan bahwa nilai regresi pada
bulan Desember jauh lebih besar dibandingkan pada bulan Januari di ketiga stasiun.
serta verifikasi model terhadap tinggi gelombang menunjukkan nilai RMSE sekitar
0.75 m hingga 0.78 m. Adanya banyak faktor yang sangat kompleks mempengaruhi
nilai ESN diperlukan studi lebih lanjut.
Kata kunci : angin, curah hujan, environmental sound noise, selat lombok, tinggi

ABSTRACT
Mochamad Rafif Rabbani, 26050117170001, Analysis of the Relationship of
Environmental Sound Noise (ESN) to Surface Wave Conditions in the Lombok
Strait, Nusa Tenggara Barat (Prof. Dr. Denny Nugroho Sugianto dan Teguh
Arif Pianto)
Lombok Strait waters is one of the waters in Indonesia that has important benefits
for the surrounding community and its complex natural factors such as
oceanography, example related to noise. Acoustic Beach Tomography is a
technology capable of recording disturbances in the form of environmental
disturbances or noise. It has been installed at 3 locations in the Lombok Strait
with data output in the format of RAW (Read After Write) and ESN (Environmental
Sound Noise) data. The ESN data is used to monitor environmental conditions
around the transducer by only receiving the process without transmitting from the
tomographic acoustic pair station which is then converted using MATLAB with std
ESN units (Standard Deviation ESN). A comparison of ESN values is carried out
to observe the shape of the environment around the transducer installed using 3
comparison variables, namely, Wind Speed, Rainfall, and Significant Wave Height.
Processing is done using polynomial regression analysis and Principal
Components Analysis. The results show that the regression value in December is
much larger than in January at the three stations. as well as model verification of
wave height shows RMSE values around 0.75 m to 0.78 m. The existence of many
very complex factors that affect the value of ESN requires further study.
