Hubungan Indeks Keanekaragaman Makrozoobentos dengan

Kualitas Air Sungai Juri Pasuruan yang Tercemar Limbah

Pemotongan Ayam

Correlation between Macrozoobenthos Diversity Index and Water Quality of

Pasuruan Juri River Polluted by Chicken Slaughterhouse Waste

Sungai Welang merupakan sungai yang mengalir dari Pegunungan Arjuna

dan bermuara di pantai Utara Pulau Jawa yang memiliki beberapa anak sungai salah

satunya yaitu Sungai Juri. Berdasarkan letaknya Sungai Juri melewati banyak

permukiman sehingga banyak sampah yang dibuang di aliran Sungai Juri, salah

satunya yaitu limbah pemotongan ayam yang dibuang langsung di salah satu aliran

sungai Juri. Limbah pemotongan ayam berbahaya untuk lingkungan karena

mengandung banyak senyawa organik yang dapat memberikan dampak bagi kulitas

air sehingga dapat memengaruhi keanekaragaman makrozoobentos di perairan

tersebut. Tujuan penilitian ini yaitu untuk mengetahui kualitas air Sungai Juri yang

tercemar limbah ayam potong berdasarkan parameter kimia, biologi, dan fisika dan

indeks keanekaragaman makrozoobentos sesuai dengan PP Nomor 22 Tahun 2021,

Sungai Juri termasuk dalam kelas 3. Makrozoobentos diidentifikasi berdasarkan

karakter morfologinya berdasarkan buku Dharma (2005) dan Edmondson (1966)

serta jurnal terkait identifikasi makrozoobentos yaitu Hernawati (2019),

Jeratthitikul, dkk., (2022), dan Lentge, dkk., (2021). kemudian ditinjau indeks

keanekaragaman menggunakan indeks Shannon Winner. Analisis data

menggunakan analisis statistik deskriptif. Hasil penelitian menunjukkan adanya

hubungan indeks keanekaragaman makrozoobentos dengan kualitas air yang yaitu

korelasi positif pada parameter suhu, sedangkan parameter pH, DO, BOD, dan

COD menunujukkan adanya korelasi negative. Hal ini menunjukkan adanya bahan

pencemar pada Sungai Juri seperti limbah pemotongan ayam.

Welang River is a river that flows from the Arjuna Mountains and empties

into the North coast of Java Island, which has several tributaries, one of which is

Juri River. Based on its location, the Juri River passes through many settlements so

that a lot of garbage is disposed of in the Juri River flow, one of which is chicken

slaughtering waste which is disposed of directly in one of the Juri river flows.

Chicken slaughtering waste is dangerous for the environment because it contains

many organic compounds that can have an impact on water quality so that it can

affect the diversity of macrozoobenthos in these waters. The purpose of this

research is to determine the water quality of Juri River polluted by slaughterhouse

waste based on chemical, biological, and physical parameters and the

macrozoobenthos diversity index in accordance with PP No. 22 of 2021, Juri River

is included in class 3. Macrozoobenthos were identified based on their

morphological characters based on Dharma (2005) and Edmondson (1966) books

and journals related to macrozoobenthos identification, namely Hernawati (2019),

Jeratthitikul et al, (2022), and Lentge, et al. (2021). then the diversity index was

reviewed using the Shannon Winner index. Data analysis using descriptive

statistical analysis. The results showed a relationship between the

macrozoobenthos diversity index and water quality, namely a positive correlation

in the temperature parameter, while the pH, DO, BOD, and COD parameters

showed a negative correlation. This indicates the presence of pollutants in the Juri

River such as chicken slaughtering waste.
