Research has conducted as an alternative form of advanced treatment in order to eliminate copper (Cu2+) heavy metal contained in electroplating industrial wastewater. The process is conducted biologically by utilizing the ability of mixed cultures of freshwater microalgae immobilized. The purpose of this study was to determine the removal efficiency for copper (Cu2+) using microalgae single and microalgae cultures mixed, determine the removal efficiency for copper (Cu2+) using mixed cultures microalgae which immobilized by alginate, and determine the influence of temperature and initial concentration of wastewater on the efficiency removal of copper metal (Cu2+) by mixed cultures of the immobilized microalgae. Microalgae are isolated from Setiabudi Reservoir, and purified in order to obtain Ankistrodesmus sp and Chlorella sp. These biosorbents then immobilized by adding alginate to form beads with a diameter of ± 0.5 cm. Artificial biosorbent cultivated in a growth medium Phovasoli Haematococcus Medium (PHM) in a series of batch cultures. The study consisted of three phases, namely the determination of biosorbent mobile and immobilized, optimization of temperature variations (25oC, 30oC and 35oC), and optimization of the initial concentration of wastewater (3 mg/l, 5 mg/l, 10 mg/ l, 15 mg/ l, and 15 mg l) at pH 4 and 120 minutes contact time. These used biosorbent was a single microalgae Ankistrodesmus sp and Chlorella sp and mixed cultures consisting of microalgae Ankistrodesmus sp and Chlorella sp with 1:1 ratio. The results prove that the removal efficiency for copper (Cu2+) by mixed cultures of microalgae was higher than either mobile or single immobilized. Copper (Cu2+) removal efficiency was proof depend on temperature process and the initial concentration of the wastewater. The optimal removal of copper (Cu2+) with immobilized biosorbent occurred at 30 °C with an initial concentration of waste by 17.808 mg /l with a value of 82.54% ± 0.11 for Ankistrodesmus sp; 83.66% ± 0.15 for Chlorella sp; and 86.39% ± 0.34 for a mixed cultures.

Grey water atau air yang ditimbulkan dari kegiatan mandi dan cuci merupakan proporsi terbesar dalam air limbah domestik. Pada umumnya, grey water secara langsung melewati saluran drainase tanpa pengolahan terlebih dahulu dan masuk ke Sungai Ciliwung, sehingga menyebabkan penurunan kualitas air sungai. Tujuan penelitian untuk menganalisis kadar pencemaran air pada sistem drainase, di 6 kelurahan pada segmen 2 Sungai Ciliwung (Kota Bogor). Parameter yang dianalisis adalah TSS, BOD, COD, dan Total Coliform yang dibandingkan dengan 2 baku mutu yakni berdasarkan Peraturan Menteri Lingkungan Hidup No.68 tahun 2016 dan Peraturan Pemerintah No.82 tahun 2001. Pengambilan sampel dilakukan pada pagi dan sore hari yang dianggap mewakili jam puncak timbulnya air limbah domestik. Hasil analisis menunjukkan parameter TSS berkisar 0,004-0,835 mg/L, BOD 184,260-89791,670 mg/L, COD 25,600-528,000 mg/L, dan Total Coliform 8,350x105-4,380x108 jumlah/100 mL. Parameter TSS di seluruh titik pengambilan sampel tidak melebihi baku mutu. Adapun parameter BOD dan COD ditemukan melebihi baku mutu pada titik Sukasari dan Babakan Pasar 2. Khusus parameter Total Coliform, ditemukan melebihi 3x104 jumlah/100mL di seluruh titik. Tingginya parameter BOD, COD, dan Total Coliform menunjukkan ada kecenderungan pencemaran oleh limbah domestik baik grey water maupun black water.

Tujuan Program Pengabdian kepada Masyarakat Multi 2-1 adalah perbaikan kondisi lingkungan di wilayah Kelurahan Krendang, Kecamatan Tambora, Jakarta Barat. Mitra dari kegiatan ini adalah pengelola non profit RPTRA (Ruang Publik Terpadu Ramah Anak) Krendang. Permasalahan yang dihadapi RPTRA Krendang dengan banyaknya pengunjung adalah tingginya konsumsi air yang berkorelasi dengan tingginya tagihan/rekening PDAM. Saat ini RPTRA menggunakan air dari saluran drainase sekunder untuk menyiram kebun/tanaman sebagai upaya dalam mengurangi pemakaian air PDAM, namun masuknya pencemaran air limbah domestik maupun non domestik ke saluran drainase menyebabkan penggunaan air dari saluran drainase berpotensi untuk menyebarkan logam berat dan bakteri pathogen ke dalam tanah. Metode pelaksanaan pengabdian ini yaitu (i) survey melalui wawancara untuk mengetahui kebutuhan pengelola RPTRA, (ii) pendampingan pada pengelola RPTRA agar dapat merencanakan dan membangun konstruksi sederhana guna memanfaatkan air bekas pakai (reuse) untuk menyiram tanaman, dan (iii) memberikan materi edukasi hemat air yang ditujukan pada warga/pengunjung RPTRA. Adanya pemanfaatan air bekas pakai sebagai air penyiram tanaman melalui implementasi konstruksi sarana dalam pemanfaatan air bekas pakai, yaitu tangki penampung dan pengalihan saluran air, pemasangan pembatas aliran yang dapat mengurangi konsumsi air di kran hingga 40%, serta pemasangan poster di RPTRA Krendang yang dapat memberikan edukasi kepada masyarakat agar berperilaku hemat air, terbukti hal-hal tersebut dapat memperbaiki kondisi lingkungan di RPTRA Kelurahan Krendang, Kecamatan Tambora, Jakarta Barat
