ABSTRACT
Activities of street vendors in the Riau Main Stadium Area, Pekanbaru City,
generate various types of waste, notably biomass waste comprising sugarcane
bagasse and corn cobs. The generation rate of this biomass waste reaches 117.2
kg/day of sugarcane bagasse and 12.5 kg/day of corn cobs. The carbon content
within this biomass waste can be utilized as renewable energy in the form of
biopellets, processed through pelletization and torrefaction to produce highquality,
standard-compliant energy. This study aims to identify the physical
characteristics of the resulting torrefied biopellets, analyze the effect of varying
the mass mixture ratio of the two biomass wastes on biopellet quality, combustion
characteristics, and the resulting concentrations of CO and CO2 gas emissions.
The methodology involved preparing mass mixture variations of sugarcane
bagasse and corn cobs (100%, 75%, 50%, 25%, and 0%), followed by
torrefaction at 300°C for 30 minutes. Subsequently, the biopellets were combusted
using a TLUD (Top-Lit Updraft) type gasification stove, and emissions were
tested using an air quality detector. The results indicated that the variation in
biomass waste mass influenced the physical characteristics of the torrefied
product, biopellet quality, combustion characteristics, and gas emission
concentrations. The optimal biopellet quality was observed in KSP 3, exhibiting a
moisture content of 4.95%, ash content of 3.75%, volatile matter of 51.30%, fixed
carbon of 40%, density of 0.60 g/cm³, and a calorific value of 5,480.57 kcal/kg.
These values comply with the biopellet standards stipulated by SNI 8675:2018.
The CO gas emission test results were 0.76 ppm, and CO2 gas emissions were
328.10 ppm; these concentration levels meet the ambient air quality standards
according to the Minister of Health Regulation (PERMENKES) No. 2 of 2023.
Furthermore, the combustion efficiency value was 0.0023, which complies with
SNI 7926-2013.
Keywords: biopellets, renewable energy, biomass, emissions, torrefaction
