The Potential of Sustainable Biogas Production from Macroalgae in Indonesia

Abstract

Indonesia is the second world’s major macroalgae producer after China, contributing to 28% of the global macroalgae production. Indonesia increased its macroalgae farming output from less than 4 million tons in 2010 to over 9.9 million tons in 2019. It is expected to continue rising to 13 million tons by 2024. The contribution of macroalgal products is quite significant, 60.7% of the total national aquaculture production. To achieve sustainable energy development goals in many developing countries, including Indonesia, biomass to energy technology such as the production of biogas form macroalgae has been considered one of the best options. Therefore, we aim to investigate the potential application of biomass to energy technology via the production of biogas from macroalgae as an alternative source of local power generation. Indonesia’s energy mix and several issues regarding macroalgae production are comprehensively reviewed. Additionally, we also discussed the process of macroalgal biogas production.

Trend Research Sustainable Developments Goals in Indonesia within ASEAN Nations from 2015 to 2023: A Bibliography Analysis

“…Even regionally in ASEAN, Indonesia and Malaysia appear to be actively discussing issues related to "sustainable development" in various aspects such as "sustainable biogas production" (Farobie et al, 2022); "Application of the SDG principles interior architecture" (Affandi et al, 2022); "Sustainable interior economy planning" (Marsahala et al, 2023); "ecolabel and certification (Rais & Suzianti, 2021) and so on. As we move towards the achievement of the SDGs by 2030, themes related to "sustainability" "climate change" and "environmental protection" are increasingly popular for study.…”

Extraction of Pigments and Antioxidant Activity from the Red Macroalgae Eucheuma cottonii

“…Briefly, a UV-Vis Spectrophotometer (Type U-2900, HITACHI, Japan) was used to analyze the products of the bio-pigments at wavelengths of 750, 651, 618, 614, 565, and 498.5 nm. The phycoerythrin content was calculated following a previous study [11], as shown in Equation (1).…”

“…Indonesia is a maritime country with a broader water area than land. Indonesia also has abundant marine resources consisting of animal and vegetable resources, such as coral reefs and marine macroalgae, commonly called seaweed [1]. Marine macroalgae are large algae, ranging from several centimeters (cm) to many meters.…”

Dietary macroalgae Chaetomorpha linum supplementation improves morphology of small intestine and pectoral muscle, growth performance, and meat quality of broilers

“…A combination of Undaria pinnatifida and Hizkia fusiformis has also been shown to improve overall body weight Available at www.veterinaryworld.org/Vol.17/February-2024/27.pdf gain and egg-laying performance in laying hens [16]. Considering that Indonesia is one of the world's major macroalgae producers with more than 500 macroalga species [17], the prospect of utilizing macroalgae as animal feed is promising. A locally available and easily accessible natural ingredient may be a good alternative to animal feed.…”
