“…R 2 values greater than 0.7 indicated a satisfactory model fit, implying that the response model in this study could adequately explain the dye removal, with an R 2 value of 0.84%. Additionally, statistical significance was attributed when the p -value and F -value were below 0.0001 and 123.7, respectively . Confirming statistical significance, the p -value and F -value of the studied model were found to be <0.0001 and 6.31, respectively.…”

In this study, electrochemical removal of methylene blue (MB) from water using commercially available and low-cost flexible graphite was investigated. The operating conditions such as initial dye concentration, initial solution pH, electrolyte dose, electrical potential, and operating time were investigated. The Box-Behnken experimental design (BBD) was used to optimize the system’s performance with the minimum number of tests possible, as well as to examine the independent variables’ impact on the removal efficiency, energy consumption, operating cost, and effluent MB concentration. The electrical potential and electrolyte dosage both improved the MB removal efficiency, since increased electrical potential facilitated production of oxidizing agents and increase in electrolyte dosage translated into an increase in electrical current transfer. As expected, MB removal efficiency increased with longer operational periods. The combined effects of operating time–electrical potential and electrical potential–electrolyte concentration improved the MB removal efficiency. The maximum removal efficiency (99.9%) and lowest operating cost (0.012 $/m 3 ) were obtained for initial pH 4, initial MB concentration 26.5 mg/L, electrolyte concentration 0.6 g/L, electrical potential 3 V, and operating time 30 min. The reaction kinetics was maximum for pH 5, and as the pH increased the reaction rates decreased. Consequent techno-economic assessment showed that electrochemical removal of MB using low-cost and versatile flexible graphite had a competitive advantage.

“…Pada kondisi kekurangan nitrogen, sel mikroalga menjadi lebih sensitif terhadap kondisi lingkungannya, sehingga sel mikroalga memodifikasi biosynthetic pathway untuk memproduksi dan mengakumulasi lipid netral, umumnya dalam bentuk triacylglycerol atau TAG (Binnal dan Babu, 2017;Fakhry dkk, 2015 2017) menjelaskan bahwa pada kondisi konsentrasi nitrogen yang kecil mikroalga akan mensintesis karbon terlebih dahulu melalui proses glikolisis.…”

Mikroalga memiliki kandungan lemak (lipid) dan asam lemak (fatty acid) yang dapat dikonversi menjadi salah satu energi alternatif biodiesel. Biodiesel adalah bahan bakar alternatif yang tidak beracun dan dapat terurai secara alami. Kelimpahan dan pertumbuhan mikroalga Chorella sp. yang sangat cepat dinilai ideal dan potensial untuk dijadikan sebagai bahan baku produksi bioenergi. Disisi lain mikroalga membutuhkan nutrisi seperti karbon dan nitrogen untuk pertumbuhannya.

“…Several studies reported the influence of cultivation conditions on microalgal lipid productivity (LP) using RSM approach [26]. Kiran et al [27] used RSM alongside CCD aiming for improved biomass and lipid yield of microalgae ( Oocystis sp.) by seeking the optimization of nutrient levels (namely, nitrate and phosphate) and temperature.…”
