Abstract: Phycoremediation of acid mine drainage (AMD) is an alternative to AMD treatment but has limited applications. 4% and had a pH of 7.2, 5.6, 5.1, 4.8, 4.3, 0%, 3.5%, 4% is 1.403 d -1 ,1.374 d -1 ,0.0862 d -1 ,0.0738 d -1 , and 0.0616 d -1 concentrations of 2.15 mg.L -1 and 0.62 mg.L -1 highest values of 84.28% and 98%, respectively. The obstacle in the application of AMD phycoremediation is that the characteristic of wastewater which limits the growth of microalgae, where AMD has a high metal content and low pH. In this study, Botryococcus braunii was cultured on media with variations in the addition of AMD of (v/v) 0%, 2.5%, 3%, 3.5%, respectively, on the photobioreactor. Botryococcus braunii growth rate was analyzed, as well as the effect of metal exposure and pH variations on the growth of Botryococcus braunii. Botryococcus braunii showed different growth rates, sequentially from the highest rate in the media with addition of AMD (v/v) 2.5%, 3%, . It is known that the highest growth rate of Botryococcus braunii is obtained in media with 2.5% (v/v) AMD with an initial pH of 5.6, and Fe and Mn , respectively. It is also known the ability of Botryococcus braunii to adapt to acidic conditions with Fe and Mn content, where Botryococcus braunii plays a role in increasing media pH and is able to remove Fe and Mn with the

“…Pembuangan air limbah yang masih banyak mengandung senyawa nutrisi ke badan air dapat mengakibatkan terjadinya pertumbuhan fitoplankton yang tidak terkendali (phytoplankton bloom) (Cai, Park and Li, 2013). Asthary et al (2013) menjelaskan bahwa meskipun air limbah sudah mengalami proses pengolahan, air limbah terolah (efluen) industri kertas masih mengandung senyawa organik dan unsur hara nitrogen dan fosfor yang berpotensi menyebabkan eutrofikasi apabila langsung dibuang ke badan air. Gude, Kokabian and Gadhamshetty (2013) menjelaskan bahwa dengan memanfaatkan energi dari bahan kimia (senyawa organik dan nutrisi) yang terkandung dalam air limbah, pengolahan air limbah dapat berubah dari proses yang memerlukan energi menjadi proses yang menghasilkan energi selain untuk menghilangkan polutan yang membahayakan lingkungan.…”

“…Hasil penelitian yang telah dilakukan oleh Asthary et al (2013) dan Setiawan et al (2014) menunjukkan bahwa air limbah terolah dari industri kertas dapat dijadikan media alternatif pertumbuhan S. platensis bahkan sampai komposisi 100%. Kemampuan S. platensis untuk dapat tumbuh dalam media air limbah terolah disebabkan oleh kelebihan yang dimiliki oleh S. platensis, yaitu dapat tumbuh pada kondisi media yang bersifat alkali seperti air laut dan air limbah (Kim et al, 2013) dan relatif tahan terhadap kontaminasi dari mikroorganisme lain yang dapat menggangu pertumbuhan S. platensis (Eriksen, 2008) serta fleksibel dan resisten terhadap kondisi pertumbuhan suboptimal (Rodrigues et al, 2010).…”

“…Pemanfaatkan kandungan nutrisi pada air limbah terolah dan air limbah wet scrubber sebagai media pertumbuhan S. platensis tidak hanya akan mengurangi beban biaya karena harga bahan kimia untuk pembuatan media yang mahal, tetapi juga dapat menjadi alternatif pemanfaatkan kedua air limbah tersebut yang selama ini belum optimal. Selain itu, hal ini juga dapat membantu mengatasi potensi terjadinya eutrofikasi apabila air limbah terolah dibuang langsung ke lingkungan (Asthary et al, 2013).…”

Industri kertas menghasilkan air limbah dari kegiatan produksi dan proses flue gas desulphurization (air limbah wet scrubber). Senyawa nutrisi (senyawa karbon, nitrogen, dan fosfat) yang masih terdapat dalam air limbah terolah dan air limbah wet scrubber belum dimanfaatkan secara optimal dan berpotensi sebagai media pertumbuhan Spirulina platensis. Penelitian dengan variasi komposisi air limbah dan fotoperiode (24 jam terang dan 12 jam terang/12 jam gelap) telah dilakukan dalam skala laboratorium selama 9 hari. Pengukuran pH media, pertumbuhan S. platensis (konsentrasi biomassa, laju pertumbuhan spesifik, dan waktu penggandaan), dan kandungan fikosianin dilakukan setiap hari untuk melihat pengaruh komposisi media dan perlakuan fotoperiode terhadap pertumbuhan S. platensis. Hasil menunjukkan bahwa S. platensis dapat tumbuh dengan baik pada semua komposisi air limbah terolah dan air limbah wet scrubber yang diujicobakan. Konsentrasi biomassa tertinggi sebesar 831 mg/L dan laju pertumbuhan spesifik tertinggi sebesar 0,52 hari-1 dengan waktu penggandaan 0,4 hari diperoleh dari perlakuan fotoperiode 24 jam terang. Komposisi air limbah terolah dan air limbah wet scrubber tidak memberikan pengaruh yang nyata terhadap konsentrasi biomassa, tetapi perbedaan fotoperiode sangat berpengaruh terhadap konsentrasi biomassa sehingga dalam aplikasi skala lapangan perlu mempertimbangkan sistem pencahayaan untuk pertumbuhan S. platensis yang optimal.Kata kunci: Spirulina platensis, media pertumbuhan, fotoperiode, air limbah terolah, air limbah wet scrubberThe Effect of Composition of Paper Industry Wastewater as A Growth Medium and Photoperiod on The Culture of Spirulina platensisAbstractThe paper industry produces wastewater from its production activities and the flue gas desulphurization process (wet scrubber wastewater). Nutritional compounds (carbon, nitrogen and phosphate compounds) which are still in treated wastewater and wet scrubber wastewater have not been utilized optimally and have potential as growth media of Spirulina platensis. Research on wastewater compositions and photoperiod variations (24 hours light and 12 hours light/12 hours dark) was carried out on a laboratory scale for 9 days. Measurements of medium pH, growth of S. platensis (biomass concentration, specific growth rate, and doubling time), and phycocyanin content were carried out every day to study the effect of wastewater composition and photoperiod treatment on the growth of S. platensis. The results showed that S. platensis can grow well on all compositions of treated wastewater and wet scrubber wastewater. The highest biomass concentration of 831 mg/L and the highest specific growth rate of 0.52 days-1 with a doubling time of 0,4 days is obtained from 24-hour light photoperiod treatment. The composition of treated wastewater and wet scrubber wastewater has no significant effect on the biomass concentration but the photoperiod differences greatly influence the biomass concentration so that in the field scale application it is necessary to consider the lighting system for optimal S. platensis growth.

Microalga Navicula sp., Spirulina platensis, and Chlorella vulgaris have the prospect of being a source of biofuel producers. Rapid cell growth, coupled with the ability to produce large lipids and less pollution, can be used as an alternative to biofuel development. Microalgae cultivation can utilize tapioca liquid waste. Addition of NaCl to regulate salinity, so optimum for microalgae growth. In addition it can reduce toxins by binding to dissolved cyanide acid present in the waste. This study aims to determine the effect of NaCl concentration on tapioca liquid waste on growth and lipid microalgae content. This study used an experimental method with a complete random factorial design. The first factor tested three species of microalgae. The second factor tested seven NaCl concentrations on tapioca liquid waste media. The results showed that the concentration of NaCl 35% in tapioca liquid waste culture media capable of producing biomass of C. vulgaris cells with the highest lipid content. The NaCl concentration capable of producing the highest microalgae biomass from the study can be developed to design more effective and efficient tapioca industrial waste treatment without damaging the environment but more productive, as a biofuel producer.
