“…Therefore, the low carbon society program needs to be integrated into the international community to achieve sustainable development (Nakata et al, 2011). The efforts related to this vision have been widely studied all over the world (Ali et al, 2013;Gan et al, 2013;Lutfi et al, 2018;Soccol et al, 2019;Yamin et al, 2018).…”

Mangrove forest in the coastal area in the Suli subdistrict is one of the sources of livelihood for the local people. The objective of this research is to analyze the public perception of the coastal community towards mangrove forests. The analysis was carried out using a questionnaire-multilevel scale with the level of assessment that refers to the Likert scale. The questionnaires, which were disseminated to 100 respondents, contained questions about the public perception in the coastal mangrove area. The questions were divided into 5 part questions, namely: 4 questions for the public perception towards ecological functions, 7 questions for community participation, 5 questions for economic benefit, 5 questions for social and culture, and 5 questions for government regulation. The results revealed that the average public perception towards the ecological functions of mangrove was good, with a value of 4.11 (in category 4). The public perception towards public participation was also good, with a value of 3.69 (in category 4). Moreover, the public perception about the economic benefits of mangrove was quite good, with a value of 3.37 (in category 3). The social and culture was quite good, with a value of 3.32 (in category 3). Finally, the public perception towards government regulation (law enforcement) was good, with a value of 3.57 (in category 4). Based on the results, the average value was 3.61, which means that mangroves management is good (in category 4) based on the perceptions of a coastal community in the Suli Subdistrict. The level of education does not affect the perception of the importance of mangrove management. This was caused by the existence of local wisdom, which considers that mangroves are the nails of the earth that can prevent coastal abrasion. This local wisdom is maintained up to now, where the local community formed a group of mangrove lovers that aims to plant and conserve mangroves.

“…One of the problems arising from this policy is the increasing waste of palm oil products [10,11] in the form of used cooking oil which is frying waste. Used cooking oil can cause water and soil pollution if it is disposed of carelessly [12], but it can be used as "an environmentally friendly fuel".…”

Indonesia is committed to accelerating the clean energy transition through the biodiesel policy to achieve net zero emission. The commitment to use palm oil as a biofuel base material will support Indonesia in achieving its energy security and energy mix target of 23% in 2025. This article discussed the characteristics of the blended fuel between biofuel from used cooking oil and Dexlite from PERTAMINA products. The blending process is carried out with the biofuel: Dexlite ratio as follows: 5:95, 10:90, 15:85 20:80, 25:75 and 30:70. The results revealed that the best experiments for acid number were obtained at the B5 blending ratio of 0.039 mgKOH/(g sample), saponification number at the B5 blending ratio of 1.066 mgKOH/(g sample), flash point at the B20 blending ratio at a temperature of 101°C, 90% distillation at the B10 blending ratio at a temperature of 213°C, and the density at the blending ratio B15 is 837 kg/m3. From these results, only the density parameter does not meet the biodiesel quality standards based on SNI 7182:2015. These results indicate that the addition of 30% biofuel to Dexlite can still be used as a fuel for diesel vehicles by applying a better washing method for KOH catalyst residue and unreacted methanol residue.

“…Agricultural wastes such as oil palm empty fruit bunches (OPEFB) and rice husks are abundant in South East Asian countries such as Indonesia and Malaysia [6,7]. Indonesia, as an agriculture country, produced 28 million tons of palm oil [8] and 70 million tons of rice annually resulted in the high rate of agricultural waste [9]. The waste becomes a social problem that has to manage immediately.…”

Biomass-based energy from agricultural wastes is a promising alternative energy source since its abundant supply and renewable. Biomass is converted into gas and liquid fuel through biochemical or thermochemical treatments. In this work, oil palm empty fruit bunches (OPEFB) and rice husk are pyrolyzed to produce gas and liquid fuel. The reactor temperature and feed mass are varied to obtain the best operating condition in a semi-batch pyrolysis reactor. The experimental results showed that the best operating temperature in pyrolysis process to produce bio-oils from OPEFB and rice husk was at 500 °C with 4.3 % (w/w) and 2.6 % (w/w) of bio-oil yields, respectively. The pyrolysis product distribution and their chemical composition are strongly affected by operating condition and the types of biomass. The GC-MS analysis results showed that the primary pyrolysis products components consist of hydrocarbons and oxygenated compounds such as carboxylic acids, phenols, ketones and aldehydes. Thermodynamic properties such as thermal conductivity of the biomass also influenced the product distribution of the biomass pyrolysis.
