ABSTRAK
Arbi Wahid. 26050118130064. Analisis Komponen Harmonik Pasang Surut
Dengan Metode Admiralty Dan Least Square Di Pantai Gesing, Kabupaten Gunung
Kidul, Daerah Istimewa Yogyakarta (Dwi Haryo Ismunarti dan Gentur
Handoyo).
Nhjb ZZZZZGunung Kidul, Yogyakarta. Secara faktual saat ini Pantai
Gesing telah dimanfaatkan sebagai tempat kegiatan tambat labuh perahu/kapal
perikanan guna mendaratkan hasil tangkapan, atau melakukan persiapan untuk
melaut kembali (memuat logistik perahu dan awak perahu) oleh lebih kurang 100
perahu nelayan setiap harinya. Ketersediaan data pasang surut yang akurat dan
kontinu di perairan Pantai Gesing Kabupaten Gunung Kidul Yogyakarta masih
sangat terbatas. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik
dan tipe pasang surut serta elevasi muka air rencana berdasarkan data pasang surut
pengamatan dengan metode admiralty dan least square. Hasil penelitian ini
menunjukkan bahwa tipe pasang surut perairan Pantai Gesing adalah campuran
condong ke harian ganda dengan nilai bilangan formzahl sebesar 0,59 dengan
metode admiralty dan hasil dari metode least square menunjukkan bilangan
formzahl sebesar 0,85. Nilai elevasi muka air yang dapat digunakan untuk bidang
acuan referensi yang dimana dengan metode admiralty menunjukan hasil nilai
HHWL sebesar 1,61 meter; MHWL sebesar 1,22 meter; MSL sebesar 0,81 meter;
MLWL sebesar 0,4 meter LLWL sebesar 0 meter; dan nilai tunggang pasang surut
sebesar 1,423 meter. Analisis menggunakan metode least square menunjukan nilai
HHWL sebesar 2,305 meter; MHWL sebesar 1,695 meter; MSL sebesar 0,81 meter;
MLWL sebesar -0,035 meter LLWL sebesar -0,645 meter; dan nilai tunggang
pasang surut sebesar 2,95 meter.
Kata Kunci : pasang surut, admiralty, least square, Pantai Gesing

ABSTRACT
Arbi Wahid. 26050118130064. Analysis of Tidal Harmonic Components
Using Admiralty and Least Square Methods at Gesing Beach, Gunung Kidul
Regency, Special Region of Yogyakarta (Dwi Haryo Ismunarti and Gentur
Handoyo).
Gesing Beach is located in Girikarto Village, Panggang District, Gunung
Kidul Regency, Yogyakarta. Factually, currently, Gesing Beach has been used as a
place for mooring activities for boats/fishing vessels to land the catch, or make
preparations for returning to sea (loading boat logistics and boat crew) by
approximately 100 fishing boats every day. The availability of accurate and
continuous tidal data in the waters of Gesing Beach, Gunung Kidul Regency,
Yogyakarta is still very limited. The purpose of this study was to determine the
characteristics and types of tides and the design water level elevation based on tidal
observations using the admiralty and least square methods. The results of this study
indicate that the tidal type of Gesing Beach waters is a mixed inclined to double
daily with a formzahl number value of 0.59 using the admiralty method and the
results of the least square method showing a formzahl number of 0.85. The value of
the water level elevation that can be used for the reference reference area where
the admiralty method shows the HHWL value of 1.61 meters; MHWL of 1.22
meters; MSL of 0.81 meters; MLWL is 0.4 meters, LLWL is 0 meters; and the value
of the tidal ride is 1,423 meters. The analysis using the least square method shows
the HHWL value of 2,305 meters; MHWL of 1,695 meters; MSL of 0.81 meters;
MLWL is -0.035 meters; LLWL is -0.645 meters; and the tidal value of 2.95 meters.
