KAJIAN KERENTANAN AIR BAWAH TANAH DAN AIR PERMUKAAN
TERHADAP PENCEMARAN LIMBAH CAIR

INTISARI
Seluruh kegiatan manusia akan menghasilkan entropi seperti halnya industri
tahu dan peternakan babi di Desa Ngestiharjo yang menghasilkan limbah padat dan
cair yang dapat meningkatkan risiko pencemaran air bawah tanah akibat infiltrasi
limbah cair dan pencemaran air permukaan dari aktivitas pembuangan limbah cair ke
lingkungan. Perlindungan sumber daya air bawah tanah dan air permukaan menjadi
sangat penting mengingat kebergantungan masyarakat Desa Ngestiharjo terhadap
fungsi air tersebut. Pembuatan zonasi kerentanan air bawah tanah dan air permukaan
sebagai bentuk usaha untuk melindungi sumber daya air dari potensi pencemaran.
Penelitian ini bertujuan untuk untuk mengetahui kualitas air limbah industri tahu dan
peternakan babi serta status mutu air bawah tanah dan air permukaan dan menganalisis
tingkat kerentanan pencemaran air bawah tanah dan air permukaan di Desa
Ngestiharjo serta membuat arahan pengelolaannya.
Penelitian ini menggunakan metode kombinasi kualitatif dan kuantitatif.
Metode pengumpulan data penelitian menggunakan metode survei lapangan dan
pemetaan serta uji laboratorium dengan parameter BOD, COD, TDS, TSS, Ammonia,
Sulfida, Nitrat dan Fecal Coliform. Teknik sampling yang digunakan purposive
sampling. Analisis dan evaluasi penelitian ini menggunakan metode DRASTIC dalam
menganalisis kerentanan air bawah tanah dan PCSM untuk menganalisis kerentanan
air permukaan serta metode Indeks Pencemaran untuk mengetahui status mutu air.
Metode analisis deskriptif digunakan dalam evaluasi dan arahan pengelolaan dalam
penelitian dalam bentuk perancangan desain IPAL Komunal Contructed Wetland.
Hasil penelitian menunjukkan bahwa kualitas air limbah industri tahu dan
peternakan babi melebihi baku mutu limbah yang ditentukan. Nilai indeks pencemaran
seluruh sampel air bawah tanah tercemar ringan dan air sungai tercemar sedang. Hasil
analisis kerentanan air bawah tanah menghasilkan satu tingkat klasifikasi yaitu sangat
tinggi dengan klasifikasi nilai >172 yang dipengaruhi oleh banyaknya parameter
dengan nilai sejenis. Kerentanan air permukaan menghasilkan dua tingkat kerentanan
yaitu rentan dan cukup rentan dengan parameter penggunaan lahan menjadi parameter
yang paling berpengaruh. Arahan pengelolaan berupa rancangan IPAL Komunal
Contructed Wetland dengan sistem sub-surface flow dan menggunakan tanaman
Cattail (Typha angustifolia) serta waktu tinggal selama 1,54 hari.
Kata Kunci: Kerentanan air; kualitas air; DRASTIC

ABSTRACT
All human activities will produce entropy such as the tofu industry and pig
farms in Ngestiharjo Village which produce solid and liquid waste which can increase
the risk of groundwater pollution due to infiltration of wastewater and surface water
pollution from wastewater disposal activities into the environment. Protection of
groundwater resources and surface water becomes very important considering the
dependence of the people of Ngestiharjo Village on the function of the water. The
creation of groundwater and surface water vulnerability zoning as a form of effort to
protect water resources from potential pollution. This research aims to determine the
quality of wastewater from the tofu industry and pig farm as well as the status of
groundwater and surface water quality and to analyze the level of vulnerability to
groundwater and surface water pollution in Ngestiharjo Village and to make
management directives.
This study uses a qualitative and quantitative combination methods. Methods
of collecting research data using field survey and mapping methods as well as
laboratory tests with parameters BOD, COD, TDS, TSS, Ammonia, Sulfide, Nitrate
and Fecal Coliform. The sampling technique used was purposive sampling. The
analysis and evaluation of this study uses DRASTIC method to analyze groundwater
vulnerability and PCSM method to analyze surface water vulnerability and the
Pollution Index method to determine the water quality status. Descriptive analysis
method is used in the evaluation and management directive in the research and
continued with the design of communal constructed tetland WWTP.
The results showed that the quality of the waste water quality test of the tofu
industry and pig farms exceed the specified waste quality standards. The pollution
index value of all underground water samples is lightly polluted and also river water
is moderately polluted. The results of the groundwater vulnerability analysis resulted
in one classification level, which is very high with a classification value of > 172 which
is influenced by the number of parameters with similar values. Surface water
vulnerability resulted two levels of vulnerability, namely vulnerable and moderately
vulnerable with land use parameters being the most influential parameter. The
management directves is in the form of a Communal Constructed Wetland WWTP
design with a sub-surface flow system and using Cattail (Typha angustifolia) plants
and a detention time of 1,54 days.
