Abstract

Kadmium merupakan bahan beracun yang menyebabkan keracunan kronik pada manusia, maka tingkat maksimun yang diperbolehkan di perairan adalah 0,01 mg/L (PP No 82 Th 2001 Tentang Kualitas Air). Penelitian ini bertujuan (1) mengidentifikasi gambaran umum kualitas air Sungai Kaligarang, (2) Mengidentifikasi konsentrasi logam berat Kadmium (Cd) di Sungai Kaligarang, serta (3) mengidentifikasi akumulasi logam berat Cd pada ikan wader merah (Puntius bramoides C.V) yang hidup di Sungai Kaligarang. Penelitian ini merupakan penelitian observasi eksploratif dengan pendekatan kuantitatif yang bertujuan untuk menggambarkan kandungan logam berat Cd pada air dan ikan wader merah di Sungai Kaligarang. Penentuan lokasi pengambilan sampel secara purposif sampling. Hasil penelitian menunjukkan bahwa parameter lingkungan berupa Suhu, pH, BOD, DO di Sungai Kaligarang tidak melebihi baku mutu berdasarkan mutu air penggolongan kelas I. Parameter logam berat Cd dalam air tidak melebihi aturan yang ditetapkan PP Nomor 82 Th 2001 tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air. Kadar logam berat yang terkandung pada ikan wader merah masih berada di bawah baku mutu yang ditetapkan baik dari FDR New Zealand, FAO, Serta SNI. 7387.2009, Tentang Batas Maksimum Cemaran logam Berat Dalam Pangan.Cadmium is a toxic substance that causes chronic poisoning in humans and the maximum permissible level in the water is 0.01 mg / L. (Th Government Regulation No. 82 of 2001 on water quality). This study aimes to (1) identify general description of Kaligarang water quality, (2) heavy metalconcentrations of Cadmium (Cd ) in Kaligarang river and (3) identifying Cd accumulation of heavy metal in red Wader fish. This research is an observational exploration with a quantitative approach that aims to describe the level of heavy metal Cd in water and wader in Kaligarang. The location is determined by sampling study with purposive sampling. The result shows that the environmental parameters such as temperature, pH, BOD, DO of Kaligarang does not exceed the quality standard as applied by the classification of water quality class I. Parameter of heavy metals Cd in the water does not exceed the rules as set by the PP . No. 82 Th 2001 on management of water quality and red water pollution control. Heavy metal levelcontained in red wader is still below the quality standard as set by both FDR New Zealand, FAO, and SNI.7387.2009 about maximum level of heavy metal pollution in food.

Abstract

The groundwater condition at converted agricultural land has decreased water quality because of previous agricultural processes, so the water quality index is essential to know. This study aims to measure the groundwater quality index in residential wells on the converted agricultural land, determine the dominant parameters that form the Water Quality Index (WQI) in dug wells and drilled wells on the converted agricultural land, and determine the effect depth and age of wells on WQI. The research design was descriptive exploratory with WQI as the dependent variable and the depth and age of the well as the independent variable. With purposive sampling, 32 points of dug and drilled wells in different locations were chosen. Multiple linear regression was applied for data analysis. From the findings, it can be concluded that the minimum WQI value in dug well water is 76.9, and the average maximum WQI value in dug well water is 92.3. There are 8 points in dug well water with WQI in a good category or quality-2 category (71-90), and 15 dug well points have WQI in a very good quality category or quality-1 category (91-100). This value indicates that the dug well water quality in the research location is still classified as eligible for consumption. The dominant parameters that form WQI values in dug and drilled wells are manganese, cadmium, iron, with a value of -0.918 -0.886 -0.790. The depth and age of the well affect the water quality index. The depth of the well has a stronger effect on the water quality index than the age of the well.
