“…In order to create a more sustainable society, biomass is one of the prominent renewable energy sources in the future [3]. Biomass is an organic matter formed from living species, such as wood [4], agricultural crop residues [5], animal waste [6], municipal solid waste [7], algae [8], and some kind of organic waste. Indonesian biomass from the forestry sector has the potency to be developed as a bioenergy source [9], one of which is Ulin wood.…”

Biomass as a renewable and sustainable energy source is expected to solve the energy crisis problem. Ulin wood residues as a biomass source could be converted into bioenergy utilizing the pyrolysis process since its primary component is a hydrocarbon. Pyrolysis process has received many interests for bioenergy production from biomass, elevating the importance of the kinetic study of pyrolysis. The kinetic study of pyrolysis is related to the beginning stage behavior of gasification and combustion process. The kinetic mechanism of pyrolysis is analyzed using Thermogravimetry Analysis (TGA), by estimating the mass decomposition at solid-state that shows TG and DTG curve. The TG and DTG curves were analyzed to see the effect of heating rate on decomposition temperature. This experiment was performed by heating 10 mg of Ulin wood sawdust from ambient temperature to 1473 K utilizing 100 mL/min of nitrogen (N 2) gas as carrier gas at various heating rate: 5, 10, 20, and 50 K/min. The kinetic parameters were determined by applying the iso-conversional methods, the Kissinger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO) methods, and then compared the results with the non iso-conversional method, using Kissinger method. The average value of activation energy calculated using the KAS and FWO methods are 253.5514 and 245.2512 kJ/mol, with the average value of constant coefficient square (R 2) of 0.9848 and 0.9859, respectively, whereas the calculated activation energy and R 2 using the Kissinger method are 237.4478 kJ/mol and 0.8520, respectively.

“…Aliran udara dari tungku ini mengadopsi rekomendasi desain tungku ecocina (MacCarty, 2008) agar udara masuk dari bawah kayu seperti juga pada (Raman et al, 2014). Di tengah tungku diatas bahan bakar kayu adalah ruang pembakaran yang relatif tertutup agar proses pembakaran tidak dipengaruhi oleh kondisi di luar tungku dan panas di ruang pembakaran tidak hilang ke luar (Kshirsagar & Kalamkar, 2014;Woolf et al, 2017;Pasymi et al, 2018;Pradana et al, 2018).…”

<p>Keumamah is made from the preservation of eastern little tuna (Euthynnus affinis). For keumamah production, boiling of fresh eastern little tuna in water, is one of the main process which requires a lot of energy. The keumamah producers utilize three-stone like stove with wood biomass as the fuel. The stove adoption is economically motivated since the fuel is cheaper than other form of commercial energy and relatively easy to obtain. However, the stove is inefficient and wasting the wood. Inefficient burning of wood releases smoke and volatile organic compounds (VOC) which are dangerous to human health and harmful for the environment. Therefore, in this community development program, two keumamah producers, located near Lampulo fish harbour - in Banda Aceh, were introduced to better practices in utilizing biomass wood as energy source. They were firstly given the information on the reverse impacts on health and environment introduced by three-stone like stove. The team has developed an improved biomass stove with improved efficiency, less fuel consumption and much cleaner combustion. Later this clean better design biomass stove with its advantages was introduced. From the test of performance, the stoves showed: 1) faster cooking time; 2) reduce fuel consumption by nearly 30%; 3) reduced smoke; and 4) flexible usage of working space with modular design. It is the intentions of this program for the stove to benefit the keumamah producers and their workers with less expending for fuel and cleaner work environment. </p>

Experimental Research to Increase the Combustion Efficiency in the Top-Lit Updraft Principle Based Gasifier

et al. 2023

The recovery of vegetal waste for energy purposes is one of the ways to increase the amount of energy obtained from renewable sources. The Top-Lit Updraft (TLUD) gasification and combustion process is recognized as the least polluting of all other combustion processes, resulting in a sterile charcoal called biochar, which can be used as an amendment in agricultural soils. The purpose of this research was to determine the influence of excess air in the combustion area compared to the (theoretical) calculated requirement for a TLUD energy module. Most scientific publications on this topic recommend primary/secondary air flow rate ratios of 1/3 or 1/4. In this study, the two recommended ratios were tested, and it was found that better energy results correspond to the ratio of 1/3. For this 1/3 ratio, the investigations continued in order to optimize the combustion process. The results achieved demonstrate that the excess combustion air flow of 30% improves the performance of the energy module due to the increase in oxygen supply and the increase in air speed in the combustion area of the syngas resulting from gasification. Increasing the excess combustion air flow rate by +50% had the effect of lowering the temperature in the flame due to the cooling of the combustion gases caused by a too high rate of excess cold air flow.
