2023-12-31T03:16:43+00:00

Limbah cair rumah makan atau warung harus dikelola untuk mengurangi
pencemaran lingkungan badan air. Pengolahan limbah cair rumah makan dapat dilakukan dengan
berbagai cara, salah satunya dengan metode biofilter anaerobik. Pada metode ini, terdapat
mikroorganisme yang tumbuh dan berkembang di permukaan suatu media dengan membentuk lapisan
biofilm. Proses pengolahan dengan biofilter anaerobik dipengaruhi oleh beberapa faktor yakni waktu
detensi dan jenis media. Penelitian ini bertujuan untuk mengetahui pengaruh waktu detensi terhadap
penurunan konsentrasi BOD, COD, dan TSS serta kinerja proses pengolahan air limbah rumah makan
dengan media bioball. Waktu detensi yang digunakan yaitu 24, 36, dan 48 jam. Metode batch
dilakukan pada penelitian ini dengan melakukan seeding dan aklimatisasi selama 18 hari secara
keseluruhan sebelum media dikontakkan dengan limbah cair rumah makan. Penelitian menggunakan
satu reaktor dengan media bioball dan dilakukan pengambilan sampel sesuai dengan waktu detensi
yang ditentukan. Hasil penelitian menunjukkan bahwa waktu detensi mempengaruhi hasil pengolahan
yakni semakin lama waktu detensi maka semakin besar penurunan konsentrasi parameter. Hasil
efisiensi optimum dicapai pada waktu detensi 48 jam dengan penurunan BOD, COD, dan TSS berturut
turut sebesar 77% dari konsentrasi awal 562,9 mg/L, 83% dari konsentrasi awal 878,9 mg/L, dan 73%
dari konsentrasi awal 462 mg/L. Hasil penurunan terbaik ketiga parameter masih belum memenuhi
baku mutu Peraturan Gubernur Jawa Timur No. 72 Tahun 2013. Pengolahan limbah cair rumah makan
dapat dilakukan dengan kombinasi anaerobik dan aerob agar memaksimalkan penurunan konsentrasi
pencemaran.

2023-12-31T03:19:05+00:00

TPA Regional Talumelito is a final solid waste disposal place that has an operating system
using the Sanitary Landfill system which has been in operation since 2012 and has 4 cells to accommodate
the waste that enters the TPA. The source of the waste that goes to the TPA Regional Talumelito comes
from Gorontalo City, Gorontalo Regency and Bone Bolango Regency. The increasing volume of waste that
goes to the landfill causes a reduction in the capacity of the waste storage. The increase in population and
percentage of service area coverage and the potential for development land are also the reasons for the
need for additional TPA areas in the Talumelito Regional TPA. Therefore, a new cell is needed which aims
to help extend the operational life of the TPA in accommodating the volume of waste that enters the
Talumelito Regional TPA. After conducting a survey of waste generation in the service area of the
Talumelito Regional TPA using the SNI 19-3964-1994 method, a projected volume of waste that enters the
Talumelito Regional TPA for the next 10 years is projected to reach 368,966.98 tons. To be able to
accommodate the volume of incoming waste for up to 10 years, a landfill area of 1.66 ha is needed. The
available land area that can be used for additional cells at the Talumelito Regional TPA site is 5.5 ha.

EVALUASI KEBISINGAN AKIBAT AKTIVITAS TRANSPORTASI TERHADAP KENYAMANAN MASYARAKAT (STUDI KASUS JALAN SUNAN KUDUS – JALAN KUDUS JEPARA KM 1 KABUPATEN KUDUS PROVINSI JAWA TENGAH)

2023-12-31T01:45:47+00:00

ABSTRACT: Transportation activities on the main road are unavoidable. One of the impacts
that occur from transportation activities is the increase in noise pollution in the form of noise in the
area. Noise that is continuously exposed can cause health problems for people around him. The main
purpose of the study was to analyze the level of noise generated by vehicle activity as well as analyze
the comfort response of the surrounding community to the noise generated.
Noise measurement is done by taking three sampling points along Sunan Kudus street –
Kudus Jepara Km 1 street Kudus Regency. Analyze the results of noise level measurements using the
Sound Level Meter (SLM) tool and adjust the Decree of the Minister of Environment No. Kep.48 /
MENLH / 11/1996.
The average level of Day and Night (LSM) noise level averaged 86.9 dB(A). This exceeds the
standard value of noise levels that have been set for residential areas and settlements that are very
unnatural with a tolerance value of 3 dB(A) stated in the Decree of the Minister of Environment
Number: 48MENLH/11/1996 which is 55 dB(A). There is a response from residents who feel
disturbed when communicating, at rest, and disrupt the productivity of the community around the
road. This becomes a benchmark for people to feel less comfortable with the noise that occurs due to
transportation activities on Sunan Kudus Street – Kudus Jepara Km 1 Street Kudus Regency.

Abstract, Tofu waste water is waste obtained from the tofu production process in the form of liquid.
The tofu waste generated from the home industry "Pak Mul Tofu Factory" is in solid form in the form of
dregs which is the dirt from soybean cleaning, while the liquid waste produced is in the form of soaking
water, and turbid liquid waste. which is yellow-gray which if left unchecked will turn black and cause a
foul odor. The wastewater produced has COD (Chemical Oxygen Demand) content of 8740 mg/l and a TSS
(Total Suspended Solid) concentration of 477.7 mg/l. Therefore, treatment efforts are needed before waste
water is discharged into water bodies in order to overcome environmental problems caused by tofu waste
water.
In this research, the processing used is biosand filter processing using tofu dregs media, fine sand,
coarse sand and gravel. This study aims to determine the ability of the tofu dregs biosand filter as an
additional medium in reducing the concentration of COD and TSS in tofu wastewater. The variable used
in this study is the thickness of the different media in each reactor.
The results showed that the treatment of tofu waste water using a biosand filter media tofu waste was able to reduce the concentration of COD and TSS with decreasing efficiency in reactor 1 with the
composition of tofu dregs activated charcoal media, fine sand, coarse sand and gravel (10:40:20:10) cm
are 87.44% and 79.26%, respectively. In reactor 2 with the composition of tofu dregs activated charcoal
media, fine sand, coarse sand and gravel (20:10:30:2 0) cm, the efficiency values for reducing COD and
TSS concentrations were 87.44% and 79.26%, respectively. and 90.04%.
