“…The sucrose content of OPF juice is quite low, while glucose content is very high. Instead of making sugar from OPF juice, it is much easier to convert sucrose and glucose into ethanol via fermentation process [31]. Extracting sugar from oil palm frond and fermenting into alcohols as presented in Figure 4 is ideal solution to utilize the OPF juice.…”

Sap from various species palm trees in which known as neera generally produced by traditional technology in Indonesia. There are 5 well known palm species that produce Neera in Indonesia such as arenga palm, coconut tree, doub palm, nipa palm and palm oil. Neera can be utilized as raw material for various derivatives such as palm sugar, sweet palm toddy, and alcoholic toddy. Tapping of neera is a crucial step because neera prone to immediately degrade and causing poor quality of palm sugar. Traditional sugar processing has some drawbacks for example: low energy efficiency processing and off-specification products. On the other side, sugar palm neera has important antioxidant component which benefits for human that unavailable in normal white sugar from sugarcane. In this current review, characterization of neera from various palms in Indonesia and available technology on sugar palm processing such as spray dryer and membrane ultrafiltration will be discussed.

“…2C2H5OH + 2CO2 Mikroorganisme yang paling banyak digunakan untuk memproduksi bioetanol adalah ragi, khususnya Saccharomyces cerevisiae. Saccharomyces cerevisiae sering dipilih untuk produksi etanol karena sangat baik dalam melakukan fermentasi dan kemampuannya untuk tumbuh dengan cepat dibawah kondisi anaerobik dan toleransi yang tinggi terhadap etanol [22].…”

Bioethanol was an alcohol substance which can be obtained by biomass fermentation process. The purpose of this study was to determine the effect of agitation and volume of starter on yield and concentration of bioethanol produced from palm juice (Arenga pinnata Merr). Catalyst used was Saccharomyces cerevisiae. Observed variables were agitation and volume of starter in anaerobic fermentation. The experiment started with preparation of a starter followed by fermentation process. The product obtained from distillation process at temperature of 88 °C. The results showed that the higher agitation speed and volume of starter, yield and concentration of bioethanol will be higher. The highest concentration and yield obtained on the condition at a agitation of 100 rpm and 35% starter amounted to 47.618% (v/v) and 48.1411%. If it exceed that point, the changes of agitation and the addition of starter did not increase the concentration and yield of ethanol produced.

“…The sugars were rapidly consumed by cells during exponential phase for growth. The increasing of glucose and fructose indicated that sucrose was hydrolysed into its monomer which composed of glucose and fructose (Shahirah et al, 2014). During the first 3 h slightly increased in fructose while sucrose were slightly decreased but as for glucose there were no increasing occurred since the cells were intensively consumed by S. cerevisiae HC10 for the growth.…”

“…But the concentration was started to decrease after 15 h. This is because the total sugar concentration became substrate limiting factor in the system and the higher ethanol concentration gave inhibitory effect to the system itself. Apart from that, reduction in ethanol concentration may due to evaporation of ethanol from time to time during fermentation (Shahirah et al, 2014).…”

Aims:Bioethanol is an environmental friendly energy source with a lot of great prospective and become an alternative to fossil fuels .Oil palm frond juice (OPFJ) is a potential sources of sugars for bioethanol production. The present study aimed to optimize bioethanol production. Methodology and results: Bioethanol fermentation was carried out by Saccharomyces cerevisiae HC10 using OPFJ as substrate in bioreactor with 1.5 L working volume. Growth profile was performed for 42 h with sampling every 3 h interval. Effect of agitation speed (rpm) and volume of OPFJ were screened to select significant factor for high production of bioethanol. Agitation speed at 175 rpm and volume of oil OPFJ; 40% gave 5.25 g/L and 4.52 g/L of ethanol and biomass concentration, respectively. These parameters were further investigated via central composite design (CCD) of Response Surface Methodology (RSM) to maximize bioethanol production. The suggested optimum conditions for bioethanol production were agitation speed at 152 rpm and volume of OPFJ at 39.71% in which giving ethanol concentration of 4.79 g/L. Growth profile after optimization indicated that the highest ethanol concentration (5.75%) was achieved after 15 h of fermentation. Kinetic studies indicated that ethanol yield coefficient (Yp/s) due to consumption of OPFJ and productivity of ethanol was 3.5 fold and 25% increased compared to before optimization, respectively. While, in term of ethanol yield about 9% increased was observed. Conclusion, Significance and Impact of study: This showed that OPFJ can be an alternative new feedstock for bioethanol production using S. cerevisiae HC10.
