ABSTRAK&#13;
 &#13;
Teluk Ulee Lheue yang terletak di Kecamatan Peukan Bada yang merupakan&#13;
salah satu wilayah pesisir dari Kabupaten Aceh Besar yang berbatasan dengan&#13;
Kota Banda Aceh. Teluk ini terkena dampak tsunami pada tahun 2004.&#13;
sedimentasi merupakan permasalahan yang berdampak terhadap majunya garis&#13;
pantai secara bertahap di pantai Teluk Ulee Lheue. Hasil analisis ukuran ukuran&#13;
butir rata-rata sedimen berkisar antara 0.083-0.217 mm dengan rentang klasifikasi&#13;
dari pasir halus sampai pasir sangat halus. Hasil analisis nilai penyortiran sedimen&#13;
berkisar antara 0.898-3,367 (?) dengan rentang klasifikasi tersortir sangat baik&#13;
sampai tersortir sangat buruk. Hasil analisis kemencengan (skewnees) berupa&#13;
kemiringan negatif dan kemiringan sangat positif berkisar antara -0.111 sampai&#13;
0.971 (?), hal ini menjelaskan energi yang bekerja terkandang lemah dan&#13;
terkadang kuat. Hasil analisis nilai kurtosis berkisar antara 0,84 – 4,39 (?) dengan&#13;
rentang klasifikasi sangat platikurtik (datar) sampai sangat leptokurtik (sangat&#13;
tinggi memuncak). Hasil analisis tegangan dasar kritis di Teluk Ulee Lheue&#13;
berkisar antara 0,011-0,443 N/m&#13;
2&#13;
 Hasil analisis dapat disimpulkan energi&#13;
bertambah searah dengan pertambahan kedalaman, semakin besar nilai tegangan&#13;
dasar kritis maka Teluk Ulee Lheue cenderung mengalami sedimentasi. Gaya&#13;
hidrodinamika berupa gelombang memberikan energi yang lemah terhadap&#13;
pergerakan sedimen, namun pergerakan arus memberikan dampak yang cukup&#13;
relevan terhadap proses pergerakan sedimen di sekitar pantai. arus Vew memiliki&#13;
nilai yang lebih besar dari arus Vns. Hasil pengukuran batimetri pada 2006, 2012,&#13;
2015 dan 2017 menunjukkan pola kontur yang menggambarkan dampak tsunami&#13;
yang masih berproses untuk pulih ke posisi yang stabil. &#13;
Kata kunci : Teluk Ulee Lheue, sedimentasi, hidrodinamika pantai, karakter&#13;
sedimen. &#13;

ABSTRACT&#13;
 &#13;
Ulee Lheue Bay is located in Peukan Bada District which is one of the coastal&#13;
areas of Aceh Besar Regency bordering with Banda Aceh City. This bay was&#13;
affected by the tsunami in 2004. Sedimentation was a problem that affects the&#13;
gradual rise of the coastline on Ulee Lheue Bay. The result of grain size analysis&#13;
is 0.083-0.217 mm with classification from fine sand to very fine sand. The&#13;
analysis of sediment sorting value is 0.898-3.367 (?) with sorting range from very&#13;
good sorted to very poorly sorted. The result of skewness analysis is a negative&#13;
slope and a very positive slope from -0.111 to 0.971 (?), this explains that energy&#13;
sometimes weak and sometimes strong. kurtosis value from 0.84 - 4.39 (?) with&#13;
classification range is very platikurtik (flat) to highly leptokurtic (very high peak).&#13;
The result of critical shear stress analysis at Ulee Lheue Bay is between 0,0110,443&#13;
&#13;
N/m&#13;
2&#13;
, the result of analysis can be concluded that energy increase in the&#13;
same direction by increasing depth, so Ulee Lheue bay have sedimentation.&#13;
Hydrodynamic forces in the form of waves provide a weak energy to the sediment&#13;
transport, but the movement of the current provides a sufficient  relevant impact to&#13;
the process of sediment transport around the coast. The Vew current has a bigger&#13;
value than the Vns current. The bathymetry measurement results on 2006, 2012,&#13;
2015 and 2017 has shows the contour pattern that describes the impact of the&#13;
tsunami are still in process to recover to a stable position.&#13;
