[ABSTRAK
Limbah lumpur yang dihasilkan dari Instalasi Pengolahan Air Limbah (IPAL) Domestik dapat dimanfaatkan melalui pengomposan karena mengandung kandungan organik yang tinggi. Namun, kandungan logam berat pada limbah lumpur dapat menjadi penyebab utama timbulnya dampak negatif pada lingkungan dan kesehatan manusia. Tujuan dari penelitian ini adalah untuk menganalisis perubahan parameter fisik-kimia, konsentrasi dan spesiasi kimia logam Cu dan Pb pada dua campuran kompos sebagai penilaian kelayakan kedua kompos untuk digunakan sebagai pupu. Hasil penelitian menunjukkan bahwa parameter suhu, pH, dan rasio C/N pada kedua kompos telah memenuhi kualitas kompos sesuai SNI 19-7030-2004. Konsentrasi logam Cu pada kompos 1 dan kompos 2 berturut-turut adalah 150 mg/kg dan 237 mg/kg, sedangkan konsentrasi logam Pb sebesar 224 mg/kg dan 183 mg/kg. Besar konsentrasi kedua logam pada kedua kompos menghasilkan faktor resiko ekologi yang masuk ke dalam kategori resiko rendah (Er < 40). Selain itu, proses pengomposan pada penelitian ini telah mengurangi efek toksisitas kedua logam. Pada akhir pengomposan, fraksi logam Cu pada kedua kompos dominan pada fraksi organic bound yaitu sebesar 63,50% untuk kompos 1 dan 56,20% untuk kompos 2. Sedangkan logam Pb dominan pada fraksi residual yaitu sebesar 62,10% pada kompos 1 dan 71,50% pada kompos 2. Kedua fraksi ini merupakan fraksi stabil sehingga keberadaan logam Cu dan Pb tidak memberikan dampak negatif bagi lingkungan jika kedua kompos diaplikasikan ke tanah.

ABSTRACT
Sewage sludge generated from Waste Water Treatment Plant (WWTP) can be reused by composting because it contains a high organic content. However, the content of heavy metals in sewage sludge can be a major cause negative impacts on the environment and human health. The purpose of this study is to analyze the changes in the physical-chemical parameters, concentration and chemical speciation of Cu and Pb in two compost mixtures as an assessment of the feasibility of both composts to be used as fertilizer. The result showed that the parameters of temperature, pH, and C/N ratio in both compost met the standard quality of compost according to SNI 19-7030-2004. Concentration of Cu in compost 1 and compost 2 were 150 mg/kg and 237 mg/kg respectively, while the concentration of Pb were 224 mg/kg and 183 mg/kg respectively. The concentration of both metals in two composts resulted Ecological Risk factor (Er) that go into a low risk category (Er < 40). In addition, the composting process in this study reduced the toxicity effect of two metals. At the end of composting, fractions of Cu in two composts were dominant in organic bound fraction in amount of 63.50% for compost 1 and 56.20% for compost 2. While Pb were dominant in the residual fraction that is equal to 62.10% for compost 1 and 71.50% for compost 2. These fractions are the stable fracion so that the existence of Cu and Pb in two compost do not give negative impact to the environment if two composts will be applied to soil.;Sewage sludge generated from Waste Water Treatment Plant (WWTP) can be reused by composting because it contains a high organic content.

Timbulan sampah DKI Jakarta yang terus meningkat dan belum dapat tertangani dengan baik memaksa tiap sumber sampah untuk melakukan pengelolaan sendiri. Pengelolaan sampah di sumber bertujuan untuk mengurangi sampah yang diangkut dan dibuang ke TPA. Salah satu sumber sampah yang paling dominan dalam menyumbang sampah kota adalah pemukiman. Namun hingga saat ini masih banyak kawasan pemukiman yang belum melakukan pengelolaan sampah dengan baik. Hal ini dapat disebabkan oleh beberapa faktor, salah satunya adalah kondisi dari pemukiman tersebut. Rumah Susun Pinus Elok merupakan rumah susun yang ditujukan bagi masyarakat relokasi dengan tingkat ekonomi menengah kebawah. Dengan segala keterbatasan fasilitas dan pelayanan persampahan menyebabkan masalah sampah yang cukup serius di rumah susun ini. Penelitian ini bertujuan untuk mengetahui jumlah timbulan dan komposisi sampah sebagai dasar alternatif perencanaan sistem pengelolaan sampah yang dapat diterapkan di rumah susun ini. Dari hasil penelitian diperoleh bahwa rata-rata berat timbulan sampah di Rumah Susun Pinus Elok sebesar 0,229 kg/orang/hari dengan volume 1,829 L/orang/hari. Adapun komposisi sampah yang dihasilkan terdiri dari organik (65,03%), lain-lain (14,03%), plastik (12,56%), kertas (6,06%), kaca (1,37%), dan logam (0,95%). Potensi reduksi sampah di Rumah Susun Pinus Elok berkisar antara 60% - 62%. Rekomendasi sistem pengelolaan sampah yang diajukan dititikberatkan pada aspek teknis operasional. Aspek teknis operasional yang direncanakan meliputi pewadahan, pengumpulan, pemindahan, pengolahan dan pengangkutan. Konsep perencanaan aspek teknis operasional rumah susun didukung oleh aspek peraturan, peran serta masyarakat, pembiayaan, dan lembaga.

Increasing of solid waste generation in DKI Jakarta encourages the waste sources to manage their own garbage. Waste management in source will reduce the amount of solid waste disposed to landfill site. One of the most dominant source of waste in the municipal solid waste is settlement area. However, there are many neighborhoods that have not done its solid waste management. This can be caused by several factors, one of them is a condition of that settlement. Pinus Elok is a flats that intended for the relocation of the middle-low economy level. With all the limitations of facilities and waste service, it causes a serious waste problem in this flats. This study aims to determine the solid waste generation and composition as a basis for planning alternative waste management system that can be applied in this flats. The result showed that the generation of solid waste in Pinus Elok Flats is 0,229 kg/person/day with a volume of 1,829 L/person/day. The composition of waste generated consists of organic (65,03%), others (14,03%), plastics (12,56%), paper (6,06%), glass (1,37%), and metals (0,95%). Potential waste reduction in Pinus Elok Flats is in a range of 60%?62%. Recommendations of solid waste management system focused on the technical aspects of the operation. Technical aspects of the operation include storage, collection, processing, and transportation. The concept of the technical aspects of operation supported by regulatory aspects, community participation, financial, and institutions.
