“…Mikroalga (fitoplankton) merupakan organisme berukuran renik yang hidup di wilayah perairan, baik air tawar maupun air laut (Prihantini et al, 2005). Mikroalga merupakan produsen primer di wilayah perairan dengan kemampuan fotosintesis.…”

“…Salah satu hal yang perlu diperhatikan adalah faktor derajat keasaman (pH) agar metabolisme sel mikroalga tidak mengganggu. Perubahan nilai pH yang drastis dapat mempengaruhi kerja enzim serta dapat menghambat proses fotosintesis dan pertumbuhan beberapa mikroalga (Prihantini et al, 2005). Menurut Widianingsih et al (2007) menyatakan bahwa, derajat kadar pH kultur mempengaruhi tingkat fotosintetik mikroalga, dan kinerja enzim dalam proses metabolisme sel.…”

Bioflok is a microbial community consisting of bacteria, protozoa and zooplankton, as a shrimp feed supplement containing amino acids methionin, vitamins, minerals and enzymes that can help the process of digestion of feed on shrimp. Bioflux is a suspension contained in water consisting of microalgae, and bacteria that are potentially developed in the field of aquaculture that is as natural food because of high protein content as well as an alternative solution to the problem of cultivation waste. This study aims to find out how optimization of biofloc formation from Skeletonema sp., Nitzschia sp. and probiotic bacteria through the optimum salinity level used on the Walne medium. This research was conducted at Biology Laboratory of Makassar State University. This research was an experimental research using Completely Randomized Design (RAL) consisting of 5 treatments and 3 replications, ie treatment with pH 9, treatment with pH 8,5, treatment with pH 8, treatment with pH 7,5, treatment with pH 7 , pH 6.5 treatment, pH 6 treatment, and pH 5 treatment, on Walne medium using a combination of inoculant Skeletonema sp., Nitzschia sp. and probiotic bacteria. Parameters observed were biomass (dry weight) floc, floc volume, floc activity, temperature, pH, light intensity, and aeration rate. Data were analyzed using Analysis of Variance (ANOVA) and continued by Duncan test (α 0,05). The results showed that the treatment with pH 6.5 was the optimum salinity for biofloc formation shown by the highest floc biomass, the highest floc volume, and the highest floc activity with the floc volume indicator 0.01278 ml, dry weight (biomass) 0.00733 g / ml and floc activity 83.45 ml.Abstrak. Bioflok merupakan komunitas mikroba yang terdiri dari bakteria, protozoa dan zooplankton, sebagai suplemen pakan udang mengandung asam amino methionin, vitamin, mineral dan enzim yang dapat membantu proses pencernaan pakan pada udang. Bioflok merupakan suspensi yang terdapat di dalam air yang terdiri dari mikroalga, dan bakteri yang berpotensi dikembangkan dalam bidang akuakultur yaitu sebagai pakan alami karena kandungan protein yang tinggi juga sebagai alternative pemecahan masalah limbah budidaya. Penelitian ini bertujuan untuk mengetahui bagaimana optimasi pembentukan bioflok dari Skeletonema sp., Nitzschia sp. dan bakteri probiotik melalui tingkat salinitas optimum yang digunakan pada medium Walne. Penelitian ini dilakukan di Laboratorium Biologi Universitas Negeri Makassar. Penelitian ini merupakan penelitian eksperimen menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 5 perlakuan dan 3 ulangan, yaitu perlakuan dengan pH 9, perlakuan dengan pH 8,5, perlakuan dengan pH 8, perlakuan dengan pH 7,5, perlakuan dengan pH 7, perlakuan pH 6,5, perlakuan pH 6, dan perlakuan pH 5, pada medium Walne dengan menggunakan kombinasi inokulan Skeletonema sp., Nitzschia sp. dan bakteri probiotik. Parameter yang diamati yaitu biomassa (berat kering) flok, volume flok, aktivitas flok, suhu, pH, intensitas cahaya, dan laju aerasi. Data dianalisis dengan...

“…Before being used as a culture medium, tapioca liquid waste was aerated and given 5 ml of M-Bio, then incubated for one (Prihantini et al, 2005;Ikhlas et al, 2014). Furthermore, tapioca liquid waste was made according to the research treatment, which was with the concentration level of NaCl of 20, 22.5, 25, 27.5, 30, 32.5, and 35%, each treatment needed as much as 800 ml.…”

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.
