INTISARI
TPA Sampah Mojorejo di dalam operasional kegiatannya telah memiliki fasilitas
untuk mengolah lindi, akan tetapi proses pengolahan lindi di dalamnya tidak
difungsikan. Kondisi tersebut tentu dapat menimbulkan dampak negatif terhadap
komponen lingkungan di sekitarnya apabila air lindi yang dibuang belum terolah
dengan optimal. Tujuan dilakukan penelitian ini yaitu untuk menganalisis kualitas air
lindi, air sungai dan air tanah di sekitar TPA Sampah Mojorejo, mengevaluasi kriteria
desain eksisting instalasi pengolah lindi dan memberikan rekomendasi arahan
pengendalian pencemaran air lindi di TPA Sampah Mojorejo.
Metode pengumpulan data dilakukan dengan cara survei, pemetaan, uji
laboratorium dan percobaan laboratorium. Pengambilan sampel dilakukan secara
Purposive sampling. Metode laboratorium dilakukan untuk mengetahui nilai kualitas
air. Percobaan laboratorium dilakukan dengan cara mengolah air lindi menggunakan
metode aerasi dengan variasi waktu tinggal 1 jam dan 2 jam untuk mengetahui
efisiensi penyisihan parameter BOD, COD dan TSS pada air lindi. Metode analisis
data dilakukan secara matematis dan deskriptif.
Kualitas air lindi dari outlet IPL melebihi baku mutu untuk parameter BOD, COD,
TSS, dan TDS. Kualitas air sungai semakin menurun pada aliran sungai setelah outlet
air lindi dengan tingkat tercemar yaitu cemar sedang, akan tetapi kondisi air sungai
sebelum outlet air lindi juga telah tercemar.. Hasil perhitungan evaluasi standar
stream, konsentrasi percampuran antara air lindi dengan air sungai masih melebihi
baku mutu pada kualitas BOD, COD dan TSS. Kualitas air sumur di sekitar TPA
sampah tergolong dalam kondisi baik-tercemar sedang. Kondisi eksisting kriteria
desain IPL tidak memenuhi kriteria desain pada parameter kedalaman kolam (kolam
aerasi), dan parameter waktu tinggal (kolam ekualisasi dan kolam pengendapan). Hasil
percobaan mengolah lindi dengan metode aerasi didapatkan hasil efisiensi paling baik
pada variasi waktu tinggal 2 jam dengan efisiensi pengurangan BOD mencapai 66 %.
Rekomendasi pengendalian pencemaran air lindi yang diberikan yaitu dengan
mengoptimalkan instalasi pengolahan lindi dari fungsi, kriteria desain dan lokasi
penempatan. Optimalisasi IPL diterapkan pada kolam ekualisasi, aerasi dan
pengendapan.

ABSTRACT
The Mojorejo landfill in its operational activities already has facilities for
processing leachate, but the leachate treatment process in it is not enabled. This
condition can certainly harm the surrounding environmental components if the
leachate that is discharged has not been optimally treated. The purpose of this study
was to analyze the quality of leachate, river water, and groundwater around the
Mojorejo landfill, evaluate the existing design criteria for the leachate processing
installation and provide recommendations for directives on controlling leachate
pollution in the Mojorejo landfill.
Methods of data collection are carried out using surveys, mapping, laboratory
tests, and laboratory experiments. Sampling was done by purposive sampling.
Laboratory methods are carried out to determine the value of water quality.
Laboratory experiments were carried out by treating leachate using the aeration
method with variations in residence time of 1 hour and 2 hours to determine the
efficiency of BOD, COD, and TSS removal in leachate. The method of data analysis is
done mathematically and descriptively.
The quality of leachate from WWTP outlets exceeds the quality standards for BOD,
COD, TSS, and TDS parameters. The quality of river water is decreasing in the river
flow after the leachate outlet with a polluted level, namely moderately polluted, but
the condition of the river water before the leachate outlet has also been polluted. The
results of the calculation of the standard stream evaluation, the concentration of the
mixture of leachate and river water still exceeds the standard. quality on the quality
of BOD, COD, and TSS. The quality of groundwater around the landfill is classified
as good to moderately polluted. The existing conditions of the WWTP design criteria
do not meet the design criteria for the parameters of pond depth (aeration ponds) and
residence time parameters (equalization ponds and settling ponds). The experimental
results of treating leachate with the aeration method showed the best efficiency results
at a 2-hour residence time variation with a BOD reduction efficiency of up to 66%.
The recommendations for controlling leachate pollution are given by optimizing the
leachate treatment plant in terms of function, design criteria and placement location.
WWTP optimization is applied to equalization, aeration and settling ponds.
