ABSTRACT
DESCRIPTION OF Chemical Oxygen Demand (COD) LEVELS IN LIQUID
WASTE OF THE SASIRANGAN INDUSTRY AFTER ADDING
PROBIOTIC SOLUTION
Researcher: Nova Salsa Bella
Supervisor: Haitami, Tini Elyn Herlina
Sasirangan is a traditional fabric industry typical of South Kalimantan
which also drives the regional economy. The Sasirangan industry involves coloring
and dyeing processes which if not handled properly can produce environmental
pollutant waste containing high levels of COD. COD is the amount of oxygen
needed to chemically oxidize organic substances in liquid waste by utilizing an
oxidizer, namely potassium dichromate as a source of oxygen. Waste with high
COD levels can interfere with the health of humans and aquatic animals so it must
be processed first in order to meet the COD quality standard for textile liquid waste
according to Pergub Kalsel No. 36 of 2008 which is 150 mg/L. One of the waste
treatment methods is the bioremediation method with probiotic solutions. The
purpose of this study was to determine the description of COD levels in the liquid
waste of sasirangan industry after adding probiotic solution. This type of research
is descriptive analytic with a cross-sectional research design. Sasirangan waste
samples were taken from Sasirangan Village, Sungai Jingah, Banjarmasin City,
then measured and obtained COD levels of 378,1 mg/L. After that, they were treated
with 0.5% and 1% probiotic solutions for 3 days. Then the results obtained of COD
levels of 347,5 mg/L at a concentration of 0.5% and 189.5 mg/L at a concentration
of 1%. It was concluded that probiotic solutions can reduce COD levels with the
largest percentage decrease of 49.9% at a concentration of 1%. It is recommended
in later studies to examine the effectiveness of probiotic bacteria and increase
variations in the length of soaking and concentration of probiotics. In addition,
research can be carried out with other parameters such as Pb, Cr, and Cd.

ABSTRAK
GAMBARAN KADAR Chemical Oxygen Demand (COD) PADA LIMBAH
INDUSTRI SASIRANGAN SETELAH PEMBERIAN
LARUTAN PROBIOTIK

Sasirangan adalah industri kain tradisional khas Kalimantan Selatan yang
turut menggerakkan roda perekonomian daerah. Industri sasirangan melibatkan
proses pewarnaan dan pencelupan yang apabila tidak ditangani dengan baik dapat
menghasilkan limbah pencemar lingkungan yang mengandung kadar COD yang
tinggi. COD merupakan jumlah oksigen yang diperlukan untuk mengoksidasi zat
organik dalam limbah cair secara kimiawi dengan memanfaatkan oksidator yaitu
kalium dikromat sebagai sumber oksigen. Limbah dengan kadar COD tinggi dapat
mengganggu kesehatan manusia dan hewan perairan sehingga harus diolah terlebih
dahulu agar memenuhi baku mutu COD limbah cair tekstil menurut Pergub Kalsel
No. 36 Tahun 2008 yaitu 150 mg/L. Salah satu metode pengolahan limbah yaitu
metode bioremediasi dengan larutan probiotik. Tujuan penelitian ini adalah untuk
mengetahui gambaran kadar COD pada limbah industri sasirangan setelah
pemberian larutan probiotik. Jenis penelitian ini adalah deskriptif analitik dengan
rancangan penelitian cross sectional. Sampel limbah sasirangan diambil dari
Kampung Sasirangan Sungai Jingah Kota Banjarmasin kemudian diukur dan
didapat hasil kadar COD sebesar 378,1 mg/L. Setelah itu diberi perlakuan
perendaman dengan larutan probiotik konsentrasi 0,5% dan 1% selama 3 hari.
Kemudian didapat hasil kadar COD 347,5 mg/L pada konsentrasi 0,5% dan 189,5
mg/L pada konsentrasi 1%. Disimpulkan bahwa larutan probiotik dapat
menurunkan kadar COD dengan persentase penurunan terbesar sebanyak 49,9%
pada konsentrasi 1%. Disarankan pada penelitian selanjutnya untuk meneliti
mengenai efektivitas bakteri probiotik dan menambah variasi lama perendaman dan
konsentrasi probiotik. Selain itu, dapat dilakukan penelitian dengan parameter lain
seperti Pb, Cr, dan Cd.
Kata Kunci: Limbah Industri Sasirangan, COD, Probiotik
