“…Two-phase AD technology with modifications to apply in household biogas digesters using DH-JcL as feedstocks has been reviewed [18,21,26,37,38,[42][43][44][45][46]50]. Therefore no single pretreatment technology is suitable for all AD systems and substrates [100], it has been also reviewed several combination techniques for enhancing biogas production [104] made from DH-JcL, i.e : use of additives [18,21,26,42,45,46]; recycling of slurry and slurry filtrate [18,37]; variation in operational parameters [37,38,42,43,44,50]; and use of fixed film / biofilters [44].…”

Jatropha curcas Linn. capsule husk (DH-JcL) is a residu from the manufacture of Crude Jatropha Oil. Biorefinery as part of the "four R's" was required in DH-JcL for anaerobic digestion feedstock. Analysis result and literature study was concluded that DH-JcL is a material that can be managed as biogas substrate, though the nutrient levels relatively low, and a number of other material such as volatile solid, carbohydrates, cellulose ad lignin was relatively high. The establishment of DH-JcL required two phase digestion as anaerobic microbial pretreatment and pre-acidification. The efficiency of two-phase digestion was able to increase the number of technology i.e. additives; recycling of slurry; variation in operational parameters and fixed film or biofilters utilization © 2015 PG Adinurani, RS Hendroko, A Nindita, SK Wahono, M Maizirwan, A Sasmito, YA Nugroho, T Liwang.Published by Elsevier Ltd.

“…The ratio of CH4 to CO2 volumes is associated with the stages of the AD process, namely the microbial activity in biogas production [12]. A higher CH4 content will lead to a more efficient energy utilization from the AD process [14]. The stages of organic matter degradation in the AD process can be observed in The initial stage of anaerobic degradation involves microorganisms that operate through a series of fermentation processes to hydrolyze solid residues, yielding simpler organic acids that are subsequently digested to produce acetic acid [13].…”

Wasted activated sludge (WAS) a byproduct of wastewater treatment, holds significant untapped energy value. Conventional practice in DKI Jakarta involves collecting and directly disposing of WAS into landfill sites, overlooking the potential benefits of the sludge. Anaerobic digestion (AD) is a sustainable process that converts organic matter in the absence of oxygen offering a promising solution to harness this potential. The study aims to emphasize waste into energy by analyzing the volume of biogas through the Biochemical Methane Potential (BMP) value of WAS from the domestic WWTP in Setiabudi, South Jakarta. Characterization of WAS and its suitability for AD will be explored using DIN standards for 21 days. The experiment was duplicated into variants I1 and I2 and the parameters tested were pH, COD, TKN, VS, TS, concentration and volume of methane gas. In this study, the biogas yield from WAS obtained at 54,98 and 89,62 ml CH4/g VS along with the composition of biogas determined through GC readings at 61,78% CH4 and 56,08% CH4 from I1 dan I2, respectively. By optimizing AD processes, this study seeks to contribute to sustainable waste management and renewable energy production. Further research is needed regarding pre-treatment that may influence the formation of biogas.

“…Several wastes, such as pulp, wastewater, and parchment, can be used as raw materials for energy production. All mentioned wastes can be used as raw material for biogas production through anaerobic fermentation (Adinurani et al 2013;Novita et al, 2021;Setyobudi et al, 2018Setyobudi et al, , 2021bSetyobudi et al, , 2022Syarief et al, 2012) and bio briquettes through pyrolysis processes (Harsono et al, 2019;Tandiono and Endah, 2020;Yandri et al, 2021b), which can be used directly as fuels.…”

Carbon dioxide (CO2) in the atmosphere occurs as the result of various chemical, physical, and biological processes. The presence of CO2 around atmosphere greatly affects the agroforestry and agroindustry of coffee. This study aimed to describe the CO2 cycle in agroforestry and agroindustry of Gayo Arabica coffee (Coffea arabica) and net CO2 ha -1 of coffee plantation. CO2 cycle was analyzed based on the movement of CO2 around the agroforestry and agroindustry of coffee. CO2 cycle model describes net CO2, CO2 emission, CO2 reduction, and CO2 sequestration. Net CO2 ha -1 of coffee plantation was 162.75 × 10 -2 t CO2 e ha -1 , with CO2 emission was 203.84 × 10 -2 t CO2 e ha -1 , CO2 reduction was 3.10 × 10 -2 t CO2 e ha -1 , and CO2 sequestration was 363.49 × 10 -2 t CO2 e ha -1 . This research formulates the calculation of equivalent carbon emissions in the arabica coffee production system in the field and primary processing, using various methods (remote sensing analysis and calculation of direct and indirect equivalent carbon emissions). The CO2 cycle positively impacts the sustainability of agroforestry and agroindustry of Gayo Arabica coffee.
