Abstract

Research has been carried out on the characterization of biochar pores produced from bagasse through a pyrolysis process at a temperature of 110oC for 4 hours, using the Scaning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) method. The biochar of sugarcane pulp produced is then tested for its ability to absorb nitrogen content (% N-total), with the source of N is urea fertilizer through the Kjedhal method based on SNI (2801: 2010), and the source of nitrogen from a solution of ammonium sulfate (NH4)2SO4 by the titrimetric method. The SEM measurement results showed that the biochar pores were uniform and micro-sized, while the peat pores were macro in size and irregular. EDX results show that biochar is composed of 100% carbon, while peat soil consists of carbon compounds (C), Oxygen (O) Silica (Si) and Aluminum (Al). Both of biochar and peat have moisture content of 0.38% and 11.79%, ash content of 2.42% AND 24.44%, volatile content of 0.53% and 5.23% of bound or fixed carbon (cf) of 97.02% and 58.53%. The results of the biochar capacity test applied to peat soils can increase the pH of the peat from 5 to 6.5 with the ability to absorb N-total from urea (NH2)2CO and N-total fertilizer sources from ammonium sulfate (NH4)2SO4 solution of 38% - 66%, and 56.5% -84.5%.

Abstract

Dunaliella salina is a green microalgae that has the ability to produce β-carotene used in various fields, such as food supplements, natural colorant, antioxidants, anti-cancer, and anti-aging. D. salina is capable of producing large amounts of carotenoids under stressful conditions, including light and nutrient. Light is the main factor that stimulate the production of carotenoid pigments and media composition plays an important role for growth, biomass, and β-carotene production. The accumulation of β-carotene in microalgae is closely related to the type and quality of light and the composition of the culture media. This study aimed to determine the production of β-carotene in microalgae D. salina using LEDs and different culture media to select the best culture conditions for producing high value compounds. The results showed that D. salina cultured using red LED light and technical Walne media was able to produce β-carotene with the highest amount of 767,499 mg/100 g. In blue LED light and Walne Pro-analysis media, the β-carotene content was 380,522 mg/100 g, while the ZA+NPK media has the lowest value. In this study, Walne Pro-analysis media became the best culture medium for D. salina. Therefore, natural sources of β-carotene can be obtained from D. salina, so it could reduce the use of synthetic carotene in meeting global demand.
