“…Gastropods are found more often in muddy substrates because they can bind higher organic materials (Ulmaula et al, 2016;Zamkowski et al, 2013). A sandy substrate cannot be a place to strengthen the gastropod because the current can move the substrate particles so that the substrate can be shifted and moving in the other direction (Puspasari et al, 2012) and the sand substrate is more easily fragmented than the mud substrate (Sahidin et al, 2014). The organic material that settles on the substrate is the foodstuffs source for macrobentos (Shalihah et al, 2017).…”

Sedati is one of the Sidoarjo Regency's Coastal Areas, which has potential resources in capture fisheries. Many industries in Sedati have caused a decrease in the aquatic productivity and aquatic organism conditions, including gastropods. Gastropods are easy to find in various habitats, but their distribution is highly dependent on the habitat conditions such as physical, chemical and biological factors. Gastropods are sensitive to environmental changes and can withstand the environmental changes that are not too wide to be used as indicators of environmental pollution. This study aims to determine the structure of the gastropod community in the Sedati Waters. The research was performed using an observation method. The gastropod samples were taken using a dredge net, while the substrate samples were collected using Ekman grab. The gastropods found in Sedati Waters from October to December are nine species from 2 orders and six families. The species most commonly found in R. venosa, while the least is C. ventricosa. The abundance index of gastropods every month shows a marked difference between stations but not the other main parameters. The diversity index value was between 1.4846-2.0897. The evenness index value reached between 0.8284 and 0.9548. The dominance index ranged from 0.16 to 0.2299. The community structure of gastropods in the Sedati Waters, Sidoarjo, East Java shows a significant difference (p<0.05) between stations and belongs to the medium category.

“…Namun, dengan tingginya kandungan bahan organik dalam perairan akan memberikan tempat yang nyaman dan rumah yang kaya akan nutrien untuk kehidupan makrozoobentos di perairan tersebut, sehingga makrozoobentos tersebut dapat hidup dengan baik meskipun dalam perairan tersebut terkandung banyak unsur logam. Menurut Sahidin et al (2014), kehadiran karbon organik pada sedimen berbanding lurus dengan jumlah bahan organik pada sedimen. Makrozoobentos jenis polychaeta menyukai perairan dengan substrat berlumpur karena mengandung bahan organik dan karbon organik tinggi.…”

Penelitian ini bertujuan untuk mengetahui tingkat pencemaran Pb dan Cd yang terjadi di perairan Teluk Semarang. Penelitian dilakukan di 2 (dua) stasiun penelitian berbeda yaitu perairan Tambak Lorok (stasiun I) dan perairan Mangunhardjo (stasiun II). Analisa kandungan logam berat pada sedimen dilakukan dengan menggunakan AAS. Perhitungan kandungan bahan organik dilakukan dengan metode Gravimetri. Perhitungan kandungan karbon organik dilakukan dengan mengonversi dari kandungan bahan organik. Karbon merupakan unsur yang dapat mengikat unsur-unsur lain di perairan. Proses identifikasi makrozoobentos dilakukan dengan metode check list. Rata-rata konsentrasi logam berat Pb dan Cd yang didapatkan di stasiun I sebesar 15,709 mg/kg dan <0,004 mg/kg, sedangkan rata-rata konsentrasi logam berat Pb dan Cd di stasiun II sebesar 12,283 mg/kg dan <0,004 mg/kg. Famili makrozoobentos tertinggi yang didapatkan pada kedua stasiun adalah famili Archidae dan Nereidae. Analisa makrozoobentos menghasilkan nilai keanekaragaman pada stasiun I sebesar 1.3008 dan pada stasiun II sebesar 1.00424; nilai keseragaman pada stasiun I sebesar 0.80823 dan pada stasiun II sebesar 0.9141; dan nilai dominasi pada stasiun I sebesar 0.32426 dan pada stasiun II 0.38776. Nilai korelasi antara logam berat dengan karbon organik sebesar 0,632, logam berat dengan kelimpahan makrozoobentos sebesar 0,591, dan karbon organik dengan kelimpahan makrozoobentos sebesar 0,496. Nilai korelasi tersebut menunjukkan bahwa adanya hubungan yang cukup kuat antar ketiga variabel tersebut. Nilai keseragaman makrozoobentos mendekati 1 yang menunjukkan spesies cukup beragam dan tidak terjadi dominasi di kedua stasiun. Nilai keanekaragaman makrozoobentos pada kedua stasiun berada pada nilai 1>a< 3 yang menunjukkan bahwa terjadi pencemaran sedang pada kedua perairan tersebut. This research supposed to know the level of Pb and Cd pollution that occurred in Semarang Bay waters. The research was conducted in 2 (two) different research stations that were in Tambak Lorok (station I) and Mangunhardjo (station II) waters. Analysis of heavy metals in organic contents used AAS. Calculated the organic matter contents used Gravimetri method. Calculated the organic carbon with covertion from organic matter contents. Carbon is an element that can bind other elements in the water. Macrozoobenthos identify processed used check list method. The average concentration of heavy metal of Pb and Cd from station I 15,709 mg/kg and <0,004 mg/kg, and average of heavy metal concentration of Pb and Cd from station II 12,283 mg/kg and <0,004 mg/kg. Macrozoobentos analysis resulted value of diversity in station I was 1.3008 and in station II was 1.00424; uniformity value in station I was 0.80823 and value from station II was 0.9141; and dominance value from ststion I was 0.32436 and value of dominance from station II was 0.38776. Correlation value between heavy metal and organic carbon is 0,632, heavy metal and macrozoobenthos abundance is 0,591, and organic carbon and macrozoobenthos abundance is 0,496. Those correlation value indicated that there is a relation between the three variables. Uniformity value approached to one (1) that means existence of species good enough diverse and that mean there was no domination in those two (2) stations, and macrozoobenthos diversity’s value in the two (2) stations was 1> a <3 that mean there was indicated moderate pollution in both of research station.

ABSTRAKPolychaeta merupakan organisme benthos yang memiliki peran penting dalam siklus nutrien, dekomposisi, mineralisasi, magnifikasi dan penyedia makanan bagi organisme dasar laut. Penelitian ini bertujuan untuk menentukan kepadatan dan distribusi spasial Polychaeta di Pesisir Tangerang, Banten. Penelitian dilaksanakan pada bulan April-Agustus 2014 di sepanjang Pesisir Tangerang, Banten. Penelitian terdiri dari 52 stasiun terbagi ke dalam tiga lokasi berbeda (Kronjo, Cituis dan Tanjung Pasir). Hasil penelitian ditemukan 5454 spesimen yang tersebar ke dalam 25 spesies Polychaeta. Kepadatan tertinggi ditemukan pada lokasi Tanjung Pasir (151 Ind/m 2 ), diikuti Kronjo (105 Ind/m 2 ) dan terendah pada lokasi Cituis (25 Ind/m 2 ). Distribusi spasial berdasarkan analisis claster Bray-Curtis menunjukkan lokasi Kronjo membentuk satu kelompok (76,47%), Cituis membentuk lima kelompok dan Tanjung Pasir membentuk satu kelompok (72,6%). Canonical Correspondence Analysis (CCA) hubungan sebaran fraksi sedimen dengan Polychaeta menunjukkan Sternapsis scutata merupakan Polychaeta deposit feeder mendominasi pada substrat lumpur dan Exogone naidin, Capitella capitata, Scoloplos armiger, Aphrodate aculeate dan Glycera capitata merupakan Polychaeta predator mendominasi pada substrat pasir, sedangkan Ophryotracha puerilis merupakan Polychaeta cosmopolitan yang tersebar pada setiap lokasi dan stasiun. ABSTRACT Polychaeta is the benthos organisms that have an important role in nutrient cycling, decomposition, mineralization, magnification and caterers to the seabed.
