Abstract

Penggunaan deterjen di Indonesia telah menjadi kebutuhan sekunder namun pembuangan limbahnya dialirkan ke badan air setempat, dan menyebabkan pencemaran khususnya eutrofikasi. Eutrofikasi disebabkan oleh unsur P (phosphorus) yang berlebih, dan juga terkandung dalam deterjen. Pengolahan P dapat dilakukan secara biologis, karena mikroba membutuhkan P sebagai unsur yang esensial. Kompos memiliki kandungan unsur hara dan mikroba, sehingga dapat dimanfaatkan untuk pengolahan biologis. Oleh karena itu penelitian ini menggunakan kompos matang dengan rasio C/N < 20 sebagai media untuk meremoval P. Penelitian ini menggunakan variasi media (25% kompos : 75% pasir, 50% kompos : 50% pasir, 75% kompos : 25% pasir) dan variasi rasio C/N (10, 15, 20). Reaktor dijalankan selama 7 hari dan secara triplikat. Hasil dari penelitian adalah reaktor dengan komposisi 50% kompos : 50% pasir, C/N = 10 memiliki rata-rata removal tertinggi yaitu 47,7%. Sedangkan untuk removal harian tertinggi adalah reaktor dengan komposisi 25% kompos : 75% pasir, C/N = 10, dengan removal 76,2% pada hari ke-2.

The use of detergent in Indonesia has become a secondary need but its waste flows to water resources. It makes water become polluted, especially becoming eutrophication. Eutrophication is caused by P (phosphorus) > 0.02 mg/L (Muller dan Hessel dalam Murphy, 2007), and detergent is one of P sources. P removal can be treated by biological treatment, cause microorganism needs it as an essential element. Compost contains essential elements and microorganisms, so it can be used for biological treatment. This research uses compost, especially matured compost with C/N ratio < 20 to remove P with microbiological attached growth. This research uses variations such as media variations (25% compost : 75% sand, 50% compost : 50% sand, 75% compost : 25% sand) and ratio C/N variations (10, 15, 20). Reactors are running for 7 days and with three times repeating (triplicate). The result of this research is a reactor with optimum composition (50% compost : 50% sand, C/N = 10), it has a removal mean 47.7%/day. And compost that has highest removal is UDPK Compost which has big porous.
