“…The more tightly contour shows deepened. On the contrary increasingly rare contour showed shallow depth (Indrayani et al, 2015;Suprobowati, 2012;Ridoan et al, 2016). In the southeast and west parts clearly seen the contours are very rare because at that location is an area of shallow with a depth of only up <3 m. Based on Figure 3 a, b, c above shows that there is a tidal influence on the condition of the bathymetry of the lake at high tide, low tide, and MSL.…”

Siombak lake (28 ha area) was a salty lake located in Medan coastal, Indonesia. Water fluctuation influenced by the sea tide. Therefore, it needed to do morphometry dynamical study as the first impression of lake physical characteristic. The purpose of this study was to understand the dynamical of Siombak lake morphometry. The research was done in September 2016. Lake mapping was done by making 100 line zig zag and draw with ArcMap. Bathymetry showed that the bottom of the lake was sloping at the center part of west and southeast of the lake, and steeping at north, south and east. Siombak Lake has shoreline length 2,535.78 m, with SDI value 2.70. Maximum length 756 m, with maximum width 246.15 m. Lake maximum depth was 17.7 m at MSL, 18.98 m at highest tide and 16.71 m at lowest tide, with average depth 5.33 m at MSL, 6.30 m at highest tide and 4.30 m at lowest tide. Lake volume was 783,607.16 m3 at MSL, 829,395.52 m3 at highest tide and 355,544.14 m3 at lowest tide, with water debit around 32.50 – 50.17 m3s-1. Water retention time was ± 4.33 – 6.75 hours

“…Peta batimetri umumnya digunakan untuk menentukan jalur pelayaran atau navigasi (Ismail, 2014). Selain itu, data batimetri juga dapat digunakan dalam penyusunan rencana tata ruang dan pengelolaan kawasan perairan (Indrayani et al, 2015). Penelitian ini bertujuan untuk memetakan kedalaman Perairan Bangsring, Kabupaten Banyuwangi sehingga akan dihasilkan peta batimetri.…”

The objective of the present research was to map the bathymetry of the Bangsring coastal area, Banyuwangi. Depth data obtained are used to consider the suitable location for fish apartment placement. The depth of the water was measured using a single beam echosounder with a frequency of 50 Hz. The data obtained by sounding process corrected by Tidal data. The tidal data measured during sampling with the observation interval of 30 minutes. The tidal correction was performed to get the depth value relative to lowest Water Surface (LWS). The results showed the depth of the Bangsring coastal area ranged from 2-49 meters. The deepest region is in the southeast of the research area. Based on the depth of the waters, the locations that can be an alternative placement of fish apartment is located by distance of 200- 250 meters in front of Bangsring coastal area with total area approximately 30 HaPenelitian ini bertujuan untuk memetakan kedalaman perairan Bangsring, Banyuwangi. Data kedalaman yang didapat dari pemeruman selanjutnya digunakan sebagai pertimbangan untuk mencari alternatif lokasi penempatan fish apartment. Kedalaman perairan di ukur menggunakan Single Beam Echosounder dengan frekuensi 50 Hz. Pemeruman dilakukan selama 2 hari yaitu pada tanggal 17 dan 18 Maret 2016 dengan metode zig zag . Hasil pengukuran kedalaman selanjutnya di koreksi terhadap pasang surut. Pasang surut diukur selama pelaksanaan pemeruman dengan interval pengamatan 30 menit. Koreksi pasang surut dilakukan untuk mendapatkan nilai kedalaman relatif terhadap Lowest Water Surface (LWS). Hasil penelitian menunjukkan kedalaman Perairan Bangsring Berkisar antara 2-49 meter. Wilayah terdalam berada dibagian tenggara area penelitian. Berdasarkan kedalaman perairan tersebut, maka lokasi Perairan di Bangsring yang dapat dijadikan alternatif penempatan fish apartment adalah di perairan depan pantai bagian timur dengan jarak sejauh 200-250 meter dari garis pantai Bangsring dengan luas 30 Ha

“…Soeprobowati (2012) menyebutkan bahwa peta batimetri menunjukkan relief dasar danau dengan garisgaris kontur kedalaman, sehingga memberikan informasi tambahan untuk navigasi permukaan. Batimetri diperlukan untuk memahami hidrodinamika suatu perairan (Indrayani et al, 2015). Selain itu, data batimetri juga sangat penting untuk pengelolaan dan pemanfaatan berkelanjutan suatu perairan.…”

Abstract. Kelapa Gading Lake is an artificial lake located in Asahan of North Sumatera. Data on the lake morphometry is needed to determin the level of water fertility, and to know ability of lake in accepting the pollutant load. The purpose of the study was to examine aspects of the lake morphometry. The research was conducted from February to April 2016. Data collected in this research were depth, water flow, the width of the lake and around the lake. The data were processed using ArcMap. The result showed that Kelapa Gading Lake has an area approximately 11931.37 m2, with the maximum length of 161.14 m, a the maximum width of 124.72 m, and the circumference of 688.50 m. The maximum depth of 2.15 m, with the shape of the lake bottom is flat. The water volume is approximately 15033.52 m3, and the water discharge of about 0.74 to 0.92 L s-1, with a stay of lake water ± 225-226 days, the brightness of the water ranges from 0.37 to 0.48 m with the compensation depth of about 0.98 to 1.07 m, and Kelapa Gading Lake has low stability.Keywords: ArcMap, bathymetric, compensation depth, lake, morphometry Abstrak. Danau Kelapa Gading merupakan danau buatan yang berada di Kabupaten Asahan, Sumatera Utara. Data mengenai morfometri danau sangat diperlukan untuk menentukan tingkat kesuburan perairan dan juga mengetahui seberapa besar kemampuan danau dalam menerima beban pencemar. Tujuan dari penelitian ini untuk mengetahui aspek morfometri danau Kelapa Gading. Penelitian ini dilaksanakan dari Februari-April 2016. Pengambilan data yang dilakukan dalam penelitian ini adalah data kedalaman, debit air, lebar danau, dan keliling danau. Data-data tersebut diolah dengan menggunakan ArcMap. Hasil penelitian menunjukkan bahwa Danau Kelapa Gading memiliki luas sekitar 11.931,37 m2, dengan panjang maksimum 161,14 m, lebar maksimum 124,72 m, keliling 688,50 m. Kedalaman maksimum 2,15 m, dengan bentuk dasar danau rata. Volume Danau Kelapa Gading adalah 15.033,52 m3, debit air sekitar 0,74-0,92 L/s, dengan masa tinggal air danau ±225-226 hari, kecerahan air berkisar 0,37-0,48 m dengan kedalaman kompensasi sekitar 0,98-1,15 m, dan Danau Kelapa Gading memiliki stabilitas yang rendah dan akan mudah mengalami pengadukan.Kata kunci: ArcMap, batimetri, danau, kedalaman kompensasi, morfometri
