EVALUASI TINGKAT POLUTAN DARI KEGIATAN PENGELOLAAN SAMPAH DI RUMAH KOMPOS SRIKANA DAN KEPUTRAN KOTA SURABAYA

Abstract

Garbage materials are able to contaminate the environment in three ways:
physically, chemically, and biologically. The large composition of garbage require management
and processing to reduce garbage load entering the TPA. In relation to this, Dinas Kebersihan
dan Pertamanan Kota 5urabaya has initiated composting of organic wastes partly to reduce
their volume. This study was aimed at measuring pollutants in compost materials especially in
terms of CO, 502, and H25 parameters. This activity was carried out in Composting Houses of
5rikana and Keputran 5urabaya.
This descriptive study was performed by measuring CO, SOb and H25 and
laboratory examination. The population under study was composting houses (18 sites) and the
sample size was 2 composting houses.
Results showed that pollutant level of CO, 502 and H25 in the air was not exceeding
the quality standard being implemented in East Java. The CO level in 5rikana Composting
House was 4.21 «(JgjNm3) and in residential area was 3.37 «(JgjNm3). 502 level in composting
house was 12.04 «(Jg/Nm3), while outside of house of 16.71 «(JgjNm3) and in residential area
was 4.16 «(Jg/Nm3). The H25 level in composting house was 9.13 «(Jg/Nm3), outside the house
was 6.54«(JgjNm3) and in residential area was 3.22 «(JgjNm3). The CO level in Keputran
Composting House was 9.66 «(Jg/Nm3), in outside of the house was 15,74 (uq/Nrn") and in the
surrounding market was 4.18 «(Jg/Nm3). The 502 level in composting house was 6,88
«(Jg/Nm3), outside of compost house 19.38«(Jg/Nm3), and in the surrounding market was 2,76
«(Jg/Nm3). H2S level in composting house was 16,14 «(Jg/Nm3), in outside of the house was
4,49 «(JgjNm3) and in the surrounding market was 1.97 «(Jg/Nm3). Temperature, humidity, and
wind velocity lase have some influence as well but not too significant to increase pollutant
level.
It is suggested to Dinas Kebersihan dan Pertamanan Kota Surabaya to add
composting house in its list of air pollution monitoring station.
