Abstract

Pertumbuhan manusia yang semakin meningkat seiring bertambahnya waktu menyebabkan pertumbuhan infrastruktur fasilitas umum dan sosial juga terus ditingkatkan. Sekolah sebagai salah satu fasilitas sosial masyarakat juga terus bertambah, hal tersebut menuntut tersedianya fasilitas dan kebutuhannya. Air menjadi salah satu kebutuhan mendasar manusia yang pasti digunakan setiap hari. Dengan keterbatasan alam dan permasalahan keairan menuntut sekolah untuk menyediakan alternatif penyediaan air. Pemanenan air hujan menjadi salah satu alternatif yang ramah lingkungan dan ekonomis. Selama ini kebanyakan orang mengambil air tanah, baik sumur gali atau bor, yang dapat mengakibatkan penurunan tanah dan kerusakan alam. Pemanenan air hujan diharapkan dapat menjaga air tanah dan meminimalisir kebanjiran. Sistem ini dinilai ekonomis karena sumbernya yang gratis dan instalasi sistemnya yang tidak terlalu rumit dan memakan biaya. Selain berkontribusi bagi alam, adanya instalasi pemanenan air hujan diharapkan menjadi sosialisasi secara tidak langsung bagi masyarakat umum dan dapat dicontoh bagi fasilitas sosial lainnya dalam penyediaan air.

Abstract

The aim is to analyze water quality and determine the pollutant load of the Musi River in Palembang City using the QUAL2K model. The method involved collecting water-quality data (TSS, NH₃, COD, and pH), calibrating and validating the model using hydraulic and water-quality parameters, and simulating the burden on the power capacity of the polluted river. The research results show that the QUAL2Kw model has high accuracy and performs well under representative field conditions. As for the spatial distribution, TSS and NH3 concentrations tend to increase from upstream to downstream due to anthropogenic activity, but they remain within safe limits. For COD, conditions tend to exceed the river’s capacity, with marked negative values. This indicates a high organic pollution pressure and the potential to degrade the quality of the aquatic ecosystems. This model can be used as a good basis for sustainable management of river water quality.

Abstract

The increase in laundry service activities in Indonesia has an impact on the high water pollution due to the disposal of laundry waste containing chemicals such as COD, TDS, and Phosphate. Laundry waste, which is discharged directly into the environment without treatment, can lead to eutrophication, deterioration of water quality, and the death of aquatic biota. Phytoremediation with a constructed wetland system using genjer plants (Limnocharis flava) was chosen as an environmentally friendly, and low-cost treatment alternative. This study aims to analyze the effectiveness of reducing COD, TDS, and Phosphate levels of laundry waste with genjer plants in the constructed wetland system, as well as to analyze the relationship between the 0, 4th, 8th and 12th day stay time on the reduction of parameters before and after treatment. Preliminary experiments used a control reactor (without plants) and a treatment reactor (10 plants). The results of this study showed the ability to set aside the largest removal in the treatment reactor at COD levels of 88,147%, TDS of 12,776% and phosphate of 14,911% on day 12.. This shows that the constructed wetland method is relatively effective to be applied as laundry waste treatment.
