Kandungan nutrien yang ada di sedimen berpengaruh terhadap keanekaragaman dan kelimpahan makrozoobentos jika semakin berlimpah dan beranekaragam maka sungai itu memiliki kesuburan yang tinggi. Tujuan penelitian ini untuk mengetahui tekstur, konsentrasi nitrat dan fosfat pada sedimen, kelimpahan dan keanekaragaman makrozoobentos serta hubungan antara kesuburan pada sedimen dengan kelimpahan dan keanekaragaman makrozoobentos di Sungai Banjir Kanal Barat, Semarang. Penelitian ini dilaksanakan pada bulan April-Mei 2019 menggunakan teknik purposive sampling dengan total 5 stasiun. Sampel yang diambil berupa sedimen dan makrozoobentos. Metode penentuan sedimen menggunakan metode pemipetan, nitrat fosfat menggunakan spektrofotometri, untuk mengetahui hubungan antara kesuburan dengan kelimpahan dan keanekaragaman menggunakan metode PCA. Hasil penelitian yang telah dilakukan menerangkan bahwa fraksi sand berkisar 10,84-92,04%; fraksi silt berkisar antara 0-70%; fraksi clay berkisar antara 2,80-25,48%. Genus makrozoobentos yang ditemukan dikelompokan menjadi 2 kelas yaitu: Gastropoda ( Afropomus sp., Melanoides sp., Terebia sp., Terebra sp., Urosalpinx sp.) dan Bivalvia ( Anadara sp., Corbicula sp., Leiosolenus sp.). Keanekaragaman jenis makrozoobentos berkisar antara 0,45-1,96 dan termasuk dalam kategori rendah. Kelimpahan individu berkisar antara 15200-42800 ind/m³ dan kelimpahan tertinggi terdapat pada stasiun IV dan stasiun II merupakan kelimpahan terendah. Konsentrasi nitrat dan fosfat sedimen berkisar antara 0,04-0,60 mg/l untuk nitrat lalu konsentrasi fosfat berkisar antara 0,03-1,33 mg/l. Analisis PCA menyatakan konsentrasi nitrat pada sedimen berpengaruh terhadap makrozoobentos. konsentrasi nitrat di sedimen cukup berpengaruh dengan keanekaragaman jenis dan kelimpahan makrozoobentos yang ada diperairan, dan memiliki nilai koefisien korelasi sebesar 0,99 dan 0,87. The Banjir Kanal Barat River needs serious attention from various elements of the community, because the river is widely used by the community. Nutrient content in sediments affects the diversity and abundance of macrozoobenthos. The concentration of nitrate and phosphate in the sediment are used phytopentos, phytopentos is benthic food. macrozoobenthos is a bioindicator of water, if it is more abundant and diverse, the river has high fertility. The purpose of this study was to determine the texture, nitrate and phosphate concentrations in sediments, abundance and diversity of macrozoobenthos and the relationship between fertility in sediments with abundance and diversity of macrozoobenthos in the West Flood River Canal, Semarang. This research was conducted in April-May 2019 using a purposive sampling technique with a total of 5 stations. Samples taken in the form of sediments and macrozoobenthos. The results of the research that have been done explained that the sand fraction ranged from 10.84 to 92.04%; silt fraction ranges from 0-70%; clay fraction ranged from 2.80-25.48%. The macrozoobenthos genus found was classified into 2 classes, namely: Gastropods (Afropomus sp., Melanoides sp., Terebia sp., Terebra sp., Urosalpinx sp.) And Bivalvia (Anadara sp., Corbicula sp., Leiosolenus sp.). Diversity of macrozoobenthos types ranged from 0.45 to 1.96 and included in the low category.

Nitrate and phosphate sediment concentrations ranged from 0,04 to 0,60 mg / l for nitrates and then phosphate concentrations ranged from 0,03 to 1,33 mg / l. PCA analysis resulted that the concentration of nitrate in the sediment affected macrozoobenthos. Nitrate concentration in sediments is quite influential with the diversity of species and abundance of macrozoobenthos in the water, and has a correlation coefficient of 0,99 and 0,87. }, issn = {2721-6233}, pages = {300--308} doi = {10.14710/marj.v8i4.26548}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/26548} }
