ANALISIS KONDISI PERAIRAN DITINJAU DARI KANDUNGAN KLOROFIL-a, NITRAT, FOSFAT DAN TOTAL SUSPENDED SOLID (TSS) DI PERAIRAN BEDONO DEMAK Analysis of Water Conditions Based on Chlorophyll-a, Nitrate , Phosphate and Total Suspended Solid (TSS) in the Coastal waters of Bedono Demak

Abstract


ABSTRAK

 

Perairan pesisir Bedono Demak mendapat masukan dari buangan berbagai aktivitas manusia (pemukiman, pertambakan dan jalur transportasi perahu nelayan) yang mengalir ke sungai Bedono dan juga adanya hutan mangrove mengakibatkan terjadinya perubahan kualitas air pada perairan tersebut karena perairan berpotensi menjadi kaya bahan organik. Tujuan dari penelitian adalah untuk mengetahui status kesuburan perairan Bedono Demak serta mengetahui hubungan konsentrasi klorofil-a, nitrat, fosfat dan total suspended solid. Penelitian dilakukan pada bulan Desember 2018. Metode yang digunakan pada penelitian adalah metode deskriptif kuantitatif. Penentuan lokasi dilakukan secara purposive pada 3 stasiun, sedangkan sampling yang digunakan mengacu pada teknik random sebanyak 3 titik. Analisis status kesuburan perairan dengan metode TSI dan analisa data untuk mengetahui hubungan antar variabel menggunakan regresi linear berganda. Hasil dari penelitian menunjukkan bahwa konsentrasi klorofil-a berkisar antara 0,007-0,012 mg/l, nitrat 0,031-0,934 mg/l, fosfat 0,291-1,732 mg/l dan TSS 320-440 mg/l. Status kesuburan perairan Bedono termasuk kategori eutrofik sedang. Hubungan klorofil-a dengan nitrat, fosfat dan TSS di perairan Bedono menunjukkan tidak berhubungan signifikan.

 

ABSTRACT

 

The Coastal waters of Bedono Demak gets input from discharges of human activities (residential, aquaculture and fishing boat transportation lines) which flows into the river and also the existence of mangrove forest so resulted in a change of water quality in the waters because the waters enriched with organic matters.  This research aims to know the category of trophic status in Bedono Demak also to understand the correlation of chlorophyll-a, nitrate and phospate and Total Suspended Solid. This research was conducted on December 2018. The method used in this research was quantitative descriptive method. Location determination is done purposively at three stations, while the sampling used refers to a random technique of three points Trophic State Index (TSI) was used to analyze the trophic status in the coast of Bedono and data analysis to find out the correlation among variabels used multiple linear regression method. The result of this research shows that the concentration of chlorophyll-a ranged from 0,007-0,012 mg/l, nitrate 0,031-0,934 mg/l, phosphate 0,291-1,732 mg/l and TSS 320-440 mg/l. The trophic status in the coast of Bedono is categorized as moderate eutrophic. The correlation between chlorophyll-a with nitrate, phosphate and TSS had not significantly related in the Coastal waters of Bedono Demak.
