Abstract

Air limbah rumah tangga sering kali menimbulkan permasalahan ketidakseimbangan ekosistem apabila tidak dikelola dengan baik. Tujuan penelitian ini adalah untuk mengetahui efisiensi penyisihan konsentrasi air limbah domestik grey water terhadap parameter BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), dan Amoniak. Penelitian ini dilakukan pada bulan 1 Juni – 13 Agustus 2021 di Laboratorium Lingkungan Universitas Trisakti, dengan menggunakan 1 (satu) unit reaktor Lahan Basah Buatan terbuat dari kaca berukuran ukuran: panjang x lebar x tinggi = 90 cm x 30 cm x 50 cm menggunakan tanaman Pakis Air (Azolla pinnata) sebagai fitoremedian dengan waktu tinggal 2, 4, 6, 8 dan 10 hari. Hasil analisis yang diperoleh diketahui efisiensi penyisihan setiap parameter (BOD, COD, dan Amoniak) menggunakan lahan basah buatan dengan tanaman Pakis Air (Azolla pinnata) adalah 32,83% untuk BOD, 29,72% untuk COD, dan 18,01% untuk Amoniak. Hasil penelitian ini diketahui bahwa tanaman Pakis Air mampu mereduksi pencemar pada air limbah domestic khususnya terhadap jenis grey water. Hasil penelitian ini memberikan kontribusi teknologi tepat guna dalam bidang bioteknologi lingkungan yaitu pengolahan air limbah dengan sistem yang mempunyai teknologi sederhana, biaya murah, hemat energi dan ramah lingkungan yang mampu menciptakan tingkat higienis dan kenyaman masyarakat serta menjaga keberlangsungan lingkungan dimasa depan

Abstract

Household wastewater consists of 80% grey water and 20% black water. The decline in water quality can have adverse impacts on well-being. Constructed wetland is an engineered system designed to harness the ecological principles of natural wetlands to address water pollution issues. The Free Water Surface system within the constructed wetland involves the flow of water on the surface. An appropriate plant example for use in a constructed wetland is Salvinia rotundifolia. Plant acclimatization was carried out for 12 days. The reactor operation continued for 12 days using a continuous system. The percentage removal of parameters in the constructed wetland reactor were as follows: COD 23.40-84.38%, BOD 37.93-72.73%, TSS 43.24-85%, phosphate 59.47-65%, and nitrate 10.99-31.08%. The values of areal removal rate constant (kA) and volumetric removal rate constant (kV) for the constructed wetland reactor were as follows: for COD, 1.48-3.75 m/day and 0.80-22.28 /day; for BOD, 1.70-3.73 m/day and 1.43-15.59 /day; for TSS, 2.11-8.83 m/day and 1.70-22.77 /day; for phosphate, 1.40-6.61 m/day and 2.89-11.20 /day; and for nitrate, 0.18-2.32 m/day and 0.58-1.54 /day. This study demonstrates that the constructed wetland reactor with Salvinia rotundifolia plants achieves removal efficiencies of up to 85%, thus meeting the standards set by the Minister of Environment and Forestry Regulation No. 68 of 2016 regarding Domestic Wastewater Quality Standards.

Abstract

This study analyzes the application of the Job Order Costing method in determining the Cost of Goods Manufactured (COGS) at SME J'rami Farm in Bogor using a case study approach with data collection methods through interviews, observation, and document analysis. The results showed that the application of the Job Order Costing method provides a more accurate calculation compared to the method that has been used so far, thus enabling the company to set a more optimal profit margin and helping the company improve production cost efficiency. The application of this method also provides opportunities for SMEs to develop their business and be able to compete better in the market
