“…Applying the Kissinger method, they were able to determine the activation energies for the decomposition of hemicellulose (24.65 kJ.mol -1 ), cellulose (78.98 kJ.mol -1 ) and lignin (183.07 kJ.mol -1 ). The first two values heavily contrast with the reported results of Adhityatama et al [15] In the present work, four different methods were used to disclose the kinetics of decomposition of ground date kernels, namely, the Kissinger, Flynn-Wall-Ozawa, the Coats-Redfern methods and a multi-regression analysis technique.…”

Abstract: The kinetics of pyrolysis of ground date kernels was investigated using thermogravimetric analysis in order to provide the necessary information for proper biochar formation and bioreactor design. Pyrolysis was carried out at heating rates of 5, 10, 15 and 20 o C.min -1 in a flow of nitrogen. One main DTG peak was obtained that corresponded to formation of bio-char. A second diffuse peak corresponds to constant rate cracking of the char formed and complete elimination of carbon leaving an ash residue. The composition of biochar was determined using EDX . Four different methods were used to follow up the kinetics of the three steps, namely, the Kissinger, the Flynn-Wall-Ozawa, the Coats-Redfern methods and multi-regression analysis. The activation energy of the main decomposition step was determined and the values obtained using different kinetic models compared. The decomposition step simply followed first order kinetics.

“…Biomassa juga didefinisikan sebagai total jumlah materi hidup di atas permukaan pada suatu pohon dan dinyatakan dengan satuan ton berat kering per satuan luas (Brown, 1997). Biomassa merupakan bahan bakar menjanjikan untuk suplai energi terbarukan yang bisa diperoleh dengan mudah sebagai solusi untuk menggantikan permintaan energi non-terbarukan yang berlebihan seperti bahan bakar fosil (Yokohama, 2008;Adhityatama et al, 2017).…”

Biomass waste potential from tea pruning was high, however the utilization of the waste still low. Forming pellet from the waste was one of means for utilizing it to have value-added. Pelletization is a process of compressing the material to increase density value, calorific value, and to uniform the particle size. The method in tea pruning waste pelletization used because the waste is consists of dry twigs and leaves so it was easier in reducing the particle size as pellet raw material. This research purpose was to identify the wood pellet characteristics of various particle size from tea pruning waste, consisted of water content, ash content, and wood pellet density against calorific value produce. The material used in this research was tea pruning waste available all years in the experimental plantation of Reserach Institute for Tea and Cinchona Gambung that has been dried for three days. Pelletization process starts with reducing the tea pruning waste particle using Chopper machine to acquire dust particles. Afterward, those dust was separated into three treatments, which are, passed sieve number 7 mesh, 14 mesh, and 18 mesh. Calorific value produced from the wood pellet was the main factor from all pelletization process, the result show that the dust passed sieve number 18, which is the smallest particle size, has the highest calorific y value produced in the amount of 4.431 cal/g

The abundance of biomass in Indonesia are potential to be utilised as a material for biofuel production. Pyrolysis can be employed to convert biomass into syngas that can be condensed into pyrolysis oil or known as bio-oil. Biomass as a material for biofuel production is available in a large quantity thus avoid the competition with materials for food source, and inexpensive. Current bio-oil research mainly studies the process of converting biomass into bio-oil from inexpensive sources, such as food crops, timber waste and agro-industrial waste. The components of bio-oil are water and organic compounds (hydrocarbons), which are traditionally produced from petroleum. Due to the depletion of petroleum reserves, bio-oil has the potential to be developed into a source of petroleum-supporting fuels. The present study reviews the status of bio-oil research and development in Indonesia, including the potential biomass sources, the latest technologies to convert and utilise bio-oil as a fuel, and government policies on the application of bio-oil in Indonesia. This review is expected to be used as a basis for the development of bio-oil policy and scientific and technological utilisation of bio-oil in Indonesia.
