Abstract

ABSTRAKMakrozoobentos merupakan organisme yang sebagian hidupnya berada di dasar perairan, bersifat menetap, hidup relatif lama, dan bergerak relatif lamban. Makrozoobentos dapat berfungsi sebagai indikator biologi di wilayah perairan yang tercemar. Pada Kalimati Pamarayan terjadi kerusakan habitat yang ditandai dengan terjadinya ledakan jumlah ganggang (blooming algae). Dikarenakan adanya gangguan terhadap habitat makrozoobentos maka perlu dilakukan penelitian mengenai sebaran makrozoobentos sebagai data pendukung untuk pengelolaan di Sungai Kalimati Pamarayan. Penelitian dilaksanakan pada bulan November 2022. Pengambilan sampel menggunakan metode purposive sampling pada 5 stasiun pengamatan. Analisis data yang dilakukan meliputi kelimpahan makrozoobentos, indeks keanekaragaman, indeks keseragaman, indeks dominansi, indeks morisita dan tekstur sedimen. Makrozoobentos yang berhasil didapatkan terdiri atas 3 kelas invertebrata yaitu bivalvia (2 spesies), gastropoda (7 spesies), dan malacostraca (1 spesies). Parameter fisika dan kimia yang didapatkan yaitu suhu 28o-30 oC; pH air 7,1-8,1; pH sedimen 6, dan DO 6,2-8,7 mg/l. Sebaran makrozoobentos yang terdapat di lokasi penelitian yaitu mengelompok,seragam dan acak dengan tekstur sedimen silt loam dan sandy loam. Kelimpahan tertinggi yaitu 42,86 ind/m²diperoleh pada stasiun 1. Pada kelima stasiun memiliki nilai keanekaragaman sedang, nilai keseragaman tinggi, nilai dominansi rendah pada Sungai Kalimati Pamarayan.Kata Kunci: habitat, makrozoobentos, Kalimati Pamarayan, sebaranABSTRACTMacrozoobenthos are organisms that live partly at the bottom of the water, are sedentary, live relatively long, and move relatively slowly.  Macrozoobenthos can serve as a biological indicator in polluted water areas. In Pamarayan, there is habitat destruction characterized by the occurrence of blooming algae. Due to the disturbance of macrozoobenthos habitat, it is necessary to conduct research on the distribution of macrozoobenthos as supporting data for management in the Pamarayan River. The research was conducted in November 2022 through purposive sampling method at 5 observation stations. Data analysis included macrozoobenthos abundance, diversity index, uniformity index, dominance index, morisite index and sediment texture. Macrozoobenthos that were successfully obtained consisted of 3 invertebrate classes namely bivalves (2 species), gastropods (7 species), and malacostraca (1 species). Physical and chemical parameters obtained were temperature 28o-30 oC, water pH 7.1-8.1, sediment pH 6, and DO 6.2-8.7 mg/l. The distribution of macrozoobenthos found in the study site is clustered, uniform and random with silt loam and sandy loam sediment textures. The highest abundance of 42.86 ind/m² was obtained at station 1. The five stations have moderate diversity value, high uniformity value, low dominance value in Pamarayan River.Keywords: habitat, macrozoobenthos, Kalimati Pamarayan, distribution.

Abstract

ABSTRAKTeripang dan kerang merupakan organisme laut yang banyak ditemukan di Perairan Socah, Bangkalan, Madura. Kajian fenotipe dan morfometrik teripang dan kerang di Perairan Socah Bangkalan Madura diperlukan untuk memperoleh data fenotipe dan morfometrik teripang dan kerang sehingga dapat mengidentifikasi kedua biota tersebut secara spesifik dan dapat dijadikan acuan penelitian lanjutan ke arah genetik. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif dengan teknik pengumpulan sampel random sampling. Hasil penelitian menunjukkan dua jenis teripang yang berasal dari Perairan Socah memiliki nama latin Phyllophorus sp. dan Phyllophorella spiculata. Phyllophorella spiculata memiliki bentuk bulat tidak sempurna, berbeda dengan spesies Phyllophorus sp. yang memiliki bentuk bulat sempurna. Kedua spesies ini memiliki papila di seluruh tubuhnya yaitu berupa tonjolan-tonjolan kecil. Selanjutnya, kerang yang terdapat di Perairan Socah adalah Perna viridis, Anadara granosa, dan Meretrix meretrix. Ketiga kerang ini memiliki warna dan corak yang berbeda-beda. Perna viridis cenderung berwarna hijau dan hijau kehitaman, Anadara granosa berwarna kuning dengan pinggiran berwarna coklat, dan Meretrix meretrix berwarna putih polos dengan sedikit corak kekuningan. Saran dari penelitian ini adalah untuk hasil yang lebih akurat terkait penentuan klasifikasi taksonomi dari masing-masing spesies, perlu penelitian lanjutan ke arah identifikasi secara genetik.Kata kunci: biodiversitas, fenotipe, kerang, morfometrik, teripangABSTRACTSea cucumbers and shellfish are marine organisms that are often found in Socah Waters, Bangkalan, Madura. Phenotypic and morphometric studies of sea cucumbers and shellfish in Socah Bangkalan Madura waters are needed to obtain phenotypic and morphometric data on sea cucumbers and shellfish so that they can identify these two biota specifically and can be used as a reference for further genetic research. The method used in this research is a qualitative descriptive method with random sampling technique. The results of the research show that two types of sea cucumbers originating from Socah Waters have the Latin name Phyllophorus sp. and Phyllophorella spiculata. Phyllophorella spiculata has an imperfect round shape, different from the species Phyllophorus sp. which has a perfectly round shape. Both species have papillae all over their bodies, which are small protrusions. Furthermore, the shellfish found in Socah Waters are Perna viridis, Anadara granosa, and Meretrix meretrix. These three shells have different colors and patterns. Perna viridis tends to be green and blackish green, Anadara granosa is yellow with brown edges, and Meretrix meretrix is plain white with a slight yellowish pattern. The suggestion from this research is that for more accurate results regarding determining the taxonomic classification of each species, further research is needed towards genetic identification.Key words: biodiversity, phenotype, shellfish, morphometrics, sea cucumbers

Abstract

ABSTRAKKualitas perairan Sungai Siak tergolong dalam kategori tercemar. Hal ini dikarenakan banyaknya sumber polutan yang masuk ke perairan sungai. Penurunan kualitas air akan berpengaruh terhadap mahluk hidup didalamnya. Meskipun Sungai Siak telah tercemar, keberadaan ikan juaro (Pangasius polyuranodon) masih banyak ditemui. Penelitian ini akan melihat hubungan panjang berat ikan juaro yang hidup di perairan Sungai Siak yang telah tercemar. Penelitian ini dilakukan pada bulan Desember 2016 di perairan Sungai Siak dengan pengambilan sampel dilakukan sebanyak 4 kali. Metode yang digunakan dalam penelitian ini adalah metode survey. Hasil analisis menunjukan persamaan hubungan panjang-berat ikan juaro jantan W= 0,013L2,899 sedangkan pada ikan betina W= 0,017L2,805. Hubungan panjang dan berat jenis ikan jantan dan betina yang tertangkap menunjukkan pola pertumbuhan yang tidak jauh berbeda. koefisien determinasi (R2) yaitu 0.9793 ikan betina dan 0.9219 untuk ikan Jantan, ini mengartikan bahwa pertumbuhan ikan juaro di Sungai Siak menunjukan sifat alometrik negatif. Meskipun telah tejadi penurunan kualitas perairan sungai siak yang melebihi baku mutu kualitas air namun kondisi tersebut masih sesuai untuk pertumbuhan panjang-berat ikan juaro yang mendukung ketersediaan makanan ikan juaro, yang mana ikan juaro memiliki sifat oportunis, sehingga ikan ini bisa memanfaatkan semua ketersediaan makanan yang berada di perairan Sungai Siak.Kata Kunci; Alometrik, hubungan panjang berat, korelasi, pangasius polyuranodon. ABSTRACTThe water quality of the Siak River is classified as polluted. This is due to the many sources of pollutants that enter river waters. The decrease in water quality will affect the living things in it. Although the Siak River has been polluted, there are still many juaro fish (Pangasius polyuranodon) to be found. This research will look at the long-weight relationship of juaro fish that live in polluted Siak River waters. This research was conducted in December 2016 in the waters of the Siak River with 4 samplings. The method used in this research is a survey method. The results of the analysis showed the similarity of the length-weight relationship for male juaro fish W = 0.013L2.899 while for female fish W = 0.017L2.805. The relationship between length and specific gravity of male and female fish caught showed a growth pattern that was not much different. the coefficient of determination (R2) is 0.9793 for female fish and 0.9219 for male fish, this means that the growth of juaro fish in the Siak River shows negative allometric properties Even though there has been a decrease in the waters quality of the Siak River which exceeds the water quality standards, these conditions are still suitable for the growth of the length-weight of the juaro fish which supports the availability of food for the juaro fish, which the juaro fish have opportunistic characteristics, so that these fish can take advantage of all the available food availability. located in the waters of the Siak River.Keyword: Alometric, correlation, length-weight relationship, pangasius polyuranodon.
