Abstract
Reklamasi merupakan upaya manusia untuk menjawab keterbatasan lahan yang
ada di perkotaan. Dalam perkembangan selanjutnya kawasan tersebut
dimanfaatkan untuk pembangunan fasilitas perkotaan, permukiman atau
pelabuhan. Rencana pengembangan Teluk Lamong yaitu peningkatan kapasitas
bongkar muat, terminal peti kemas dan terminal multipurpose dikhawatirkan akan
berdampak negatif terhadap pola arus dan sedimentasi di Teluk Lamong. Dampak
dari sedimentasi ini dikhawatirkan akan menyebabkan pendangkalan alur
pelayaran sungai di Selat Madura. Tugas akhir ini meneliti tentang perubahan pola
arus yang terjadi di Teluk Lamong akibat adanya reklamasi dengan parameter
kecepatan arus yang terjadi pada tiap titik tinjauan dan tiap alternatif desain
reklamasi yang dimodelkan dengan SMS 11.1. Pola arus dan transpor sedimen
yang terjadi di Teluk Lamong mengalami perubahan. Besarnya sedimen pada
kondisi eksisting yaitu -638.33 m3. Selisih volume sedimentasi sebelum dan
sesudah dilakukannya reklamasi di Teluk Lamong dibagi dalam beberapa
alternatif desain, untuk alternatif desain 1 didapatkan selisih -20.9 m3, untuk
alternatif 2 didapatkan -41.7 m3. Walaupun sedimentasi bernilai negatif atau
dengan kata lain terjadi erosi, namun angka yang terjadi tidak signifikan.

Reclamation is a human attempt to address the limitations of existing urban land.
In a further development of the region used for the construction of urban facilities,
residential or ports. Lamong Bay development plans that increase the capacity of
loading and unloading, container terminal and multipurpose terminal is feared to
have a negative impact on the pattern of flow and sedimentation in the Lamong
Bay. The impact of sedimentation is feared to cause silting of river shipping
channel in the Strait of Madura. This final project examines changes in flow
patterns that occur in the Lamong Bay as a result of reclamation with parameter
flow velocity that occurs at each point and each alternative design review
reclamation is modeled with SMS 11.1. The pattern of flow and sediment
transport that occurred in the Lamong Bay change. The amount of sediment in the
existing condition -638.33 m3. Sedimentation volume difference before and after
reclamation in the Lamong Bay divided into several alternative designs,
alternative design 1 obtained difference -20.9 m3, and -41.7 m3 obtained for
alternative 2. Although sedimentation is negative, or in other words erosion, but
the number that occurred is not significant.
