STUDI KANDUNGAN NITRIT & NITRAT SUNGAI CEBONG, SUNGAI KREO KECAMATAN MIJEN DAN AIR SUMUR GALI DI DUSUN GISIKSARI KECAMATAN GUNUNGPATI SEMARANG.

Abstract

Tempat pembuangan akhir sampah Jatibarang merupakan salah satu tempat untuk menampung , mengolah sampah sehingga dampak sampah bisa dikurangi. Sistem pembuangan akhir sampah merupakan sanitari landfill. dalam praktek nya adalah Modified control landfill.Tujuan penelitian ini adalah mengukur kandungan nitrit & nitrat pada air sungai Cebong & sungai Kreo dan sumur gali dusun Gisiksari Kecamatan Gunungpati semarang. Jenis penelitian ini adalah Explanatory research, metode survey dengan pnedekatan Crossectional.Sampel air Cebong di ambil setelah melewati IPAL pertama. Air sungai Kreo di ambil setelah IPAL ke dua dan air sungai Kreo yang berdekatan dengan lokasi sumur gali di dusun Gisiksari,air sumur gali di ambil pada jarak 95 m sampai dengan lebih dari 95 meter dari sungai Kreo sebanyak 20 (total populasi). Hasil penelitian menunjukan kandungan nitrit dan nitrat di sungai Cebong sebesar 32.88 mg/l dan 3.17 mg/l. Di sungai Kreo bagian hulu kandungan nitrit dan nitratnya sebesar 42.19 mg/l dan nitrit sebesar 4.11 mg/l. sedangkan kandungan nitrit dan nitrat sungai Kreo bahian hilir sebesar 27.66 mg/l dan 2.68 mg/l. Hasil Uji Korelasi Product moment menunjukan ada hubungan bermakna antar ajarak sungai Kreo dengan kandungan nitrit dan nitrat pada air sumur gali di dusun Gisiksari Kec. Gunungpati Semarang. Untuk kandungan nitrat hubungannya sangat kuat dan nitrit hubungannya Kuat. Kata Kunci: Jarak, Lindi, Nitrit, Nitrat, TPA Jatibarang A SUTDY OF NITRIT & NITRATE CONTENTS IN CEBONG RIVER, KREO RIVER MIJEN SUBDISTRICK AND DRILLER WELL WATER AT GISIKSARI VILAGE GUNUNGPATI SUB DISTRICT SEMARANG The solid waste Disposal of Jatibrang is one place to hold an process garbages, so that the impact of those garbages can be reduced.The solid waste final Jatibrang is sanitari landfill, but for modified controll landfill. The aim of the reearch is to measure nitrit & nitrate contents in Cebong and Kreo river and drilled wel at Gisiksari vilage Gunungpati sub District. Kid of the research was and explanatory reseach using survey methode with crossectional approach.The reseach sampel Cebong river water was taken after lindi passed throught the first IPAL. Kreo river water was taken after the second IPAL and Kreo river water adjacent to drilled well location at Gisiksari vilage, Gunungpati subistric. The water of drileed well was taken in the distance of 95 meters and more than 95 meters from Kreo river, the taken sample were the amount of 20 samples. The result of this resech indicated nitrit and nitrate content at Cebong river was in the amount of 32.88 mg/l and 3.17 mg/l. In the upper resech Kreo river its nitrate content was in the amount of 42.19 mg/l and its nitrit content was in the amount of 4.11 mg/l Mean while in the down stream of Kreo river , its nitrit and nitrate content were in the amount of 27.66 mg/l and 2.68 mg/l. The corelation test of the Product Momment obtained of resulth that there is significant corelation between the distance of Kreo River and nitrit and nitrate content in the driled well water at Gisiksari vilage Gunungpati Subdistric Semarang. For the nitrate content , its corelation was very strong, meanwhile the nitirs corelation was very strong. Keyword : The Distance, Leachite, Nitrit, Nitrate
