“…The environmental and global warming consciousness has become an important policy in all countries around the world. Furthermore, the fossil fuel use has been related to some alarming environmental problems such as global warming and climate change (Tsai et al 2016 ; Vu et al 2017 ). These increasing demands for energy, together with the weakening and limited source of fossil fuels, together with the harmful impacts in the environment, are the reasons industries and governments worldwide are pursuing renewable alternatives.…”

Biomass from wetland aquatic grass and buffalo grass can be exploited for biogas production, because this substrate is plenteous and does not compete with food production. In this study, the grass substrate was physically pretreated by boiling with different retention time to increase its biodegradability and was examined in batch mode. Boiling pretreatment suggested that 100 °C with 2 h retention time was the best condition. The results showed that the optimum grass concentration in the 1:1 ratio of co-digestion mixture with manure produced the highest methane yield. The results suggested that co-digestion of buffalo grass and buffalo dung was a promising approach for improving biogas production. This study was achieved the upgraded biogas through biological purification contained 90.42% CH4 8.04% CO2 1.43% O2 and 0.11% other trace gases—a remarkable performance based on an efficiency criteria. Furthermore, the digestate has high nutrient concentrations that can potentially use as fertilizer.

“…Due to the complexity and variability of biomass chemical structures, the optimal pretreatment method and conditions depend on the types of lignocellulose present. Several structural and compositional properties were found to have impacts on the biodegradability of lignocellulosic biomass, including cellulose crystallinity, accessible surface area, degree of cellulose polymerization, presence of lignin and hemicellulose, and degree of hemicellulose acetylation (Van Soest et al, 1991;Tang et al, 2011;Saha et al, 2013;Teghammar et al, 2013;Vázquez-Rowe et al, 2015;Tsai et al, 2016;Unpaprom et al, 2017;Vu et al, 2018;Tran et al, 2019;Manmai et al, 2020). The goal of pretreatment is to alter such properties to improve biomass amenity to enzymes and microbes.…”

Pruning fruit trees is improving their full health and harvest. Fruit tree pruning leaves waste to represent an abundant amount of organic materials, and these produced during a short period. The basic fuel properties of lignocellulosic biomass from orchards were evaluated on the following fruit tree leaves obtained from pruning operations. Biomass has become a vital source of renewable energy. Biogas is one the renewable energy which can be produced by anaerobic fermentation of biomass. In this study, mango, longan and lychee trees pruning leaves waste was utilized for biogas production. These leaves were examined on proximate analysis and ultimate analysis contents are considered as carbon (C), hydrogen (H), oxygen (O), nitrogen (N) and sulfur (S). In this study, pretreatment was performed using a sodium hydroxide solution (w/v) at different concentrations as above (1, 2, 3, and 4%). For the best feedstock screening, the theoretical biochemical methane potential was confirmed. Mango leaves biomethane content was higher compared to longan and lychee leaves. Finally, this biomass was suggested further large-scale studies. Digestate from biogas system is a highly valuable nutrient and rich fertilizer.

“…Di sisi lain, penggunaan energi fosil yang masif memberikan dampak negatif bagi lingkungan. Pembakaran bahan bakar fosil melepaskan CO 2 ke atmosfer, menyebabkan peningkatan gas rumah kaca dan mengakibatkan pemanasan global serta perubahan iklim (Tsai et al, 2016). Oleh karena itu pengembangan energi alternatif sangat dibutuhkan.…”

Nowadays, the demand on fossil energy is increasing in number whereas its availability is decrease. People are still reckoned on it, despite of its rareness. Fossil energy utilized must be banned due to its negative effect. It is time for us to use renewable and eco-friendly energy (biofuel). Biogas is one of biofuel produced from anaerobic decomposition of organic matter by microorganisms. Organic waste as a by-product of our daily activities can be used as raw material to produce biogas. To use waste, means to decrease the environmental pollution problem. This research is aim to study the type of organic waste as a raw material to produce biogas through anaerobic digestion and its retention time. Organic wastes that were used in this research are domestic waste (food waste), agriculture waste (corn leaves) and industrial waste (solid and liquid waste of tofu). All of these wastes were mixed with cow dung as the starter/inoculum. As a control, the starter was used without organic waste addition. The testable retention times were 1st week until 9th week. The experimental design was Factorial Complete Randomized Design with confidence level 95%. The result showed that all the type of organic waste can be used to produce biogas through anaerobic digestion. Statistically, the average volume of biogas produced from industrial waste per week, 5794,3 ml was significantly different from any other organic waste (P=0,000). The best retention time was found on 8th week with the average volume of biogas was 3675,6 ml (P=0,006). There was no interaction between these two factors (P=0,1). This research is expected to open the people’s awareness about the management of useable organic waste as a raw material to produce biogas.
