Making briquettes from biomass feedstocks is expected to address environmental concerns as well as a solution to the scarcity of fuel. One type of waste that is produced is a lot of sawdust powder one of which sanggai sawdust powder type other than that which is not less generated is rice husk waste. Where from the two raw materials can be processed into charcoal briquettes. The objectives of this research are to know the characteristics of borang mixture of sungkai wood powder and rice husk, including: water content, density, ash content, airborne content, carbon content and calorific value. In addition to knowing the quality of charcoal briquette quality produced compared to the standard include: ASTM, SNI, JAS and BSI. This research used raw material of sungkai wood powder and rice husk with 3 replications and 5 treatments, namely: 100% sungkai wood powder, 75% sungkai wood powder: 25% rice husk, 50% sungkai wood powder: 50% rice husk, 25% Sungkai wood powder: 75% rice husk and 100% rice husk using 10% tapioca adhesive. Variation of charcoal briquettes mixture of sungkai wood powder waste and rice husk in making charcoal briquettes have significant effect on water content, ash content, content of fly content, bound carbon content and calorific value. The results showed that water content meets ASTM standards but does not meet SNI, JAS and BSI standards. Airborne content meets ASTM and JAS standards but, does not meet SNI and BSI standards. While the rest for density, ash content, bound carbon content and heating value all do not meet the standards of ASTM, SNI, JAS and BSI.Keywords: Characteristic of bioarang briquettes; Sungkai wood charcoal; Rice husk charcoal

Gemor (Nothaphoebe coriacea) is one of the plants of Non-Timber Forest Product typical of wetlands with secondary metabolite compounds such as alkaloids, steroids, flavonoids, triterpenoids, and phenolics. Besides being used as an insecticide, gemor bark also has antioxidant activities, anti-influenza, antivirus, antiherpes, and anti-inflammatory. This study aimed to encapsulate gemor bark extract using cetyltrimethylammonium bromide (CTAB)-modified nanocellulose to increase the effectiveness of its use. The result showed that gemor bark extract had an IC50 value of 39.97 ppm. In comparison, encapsulated gemor bark extract (Gemor-Nc-4 mM CTAB) had an excellent antioxidant activity with an IC50 value of 98.41 ppm and encapsulation efficiency of 53.70 %.

Production of galam wood produces bark waste that is disposed in around of the production site without processing. The use of galam bark waste is very necessary to reduce waste and its problems in the environment and optimize the potential of galam wood as a typical Kalimantan plant. In this research, modification of galam bark biomass (Malaleuca leucadendra) into hydrochar through a hydrothermal process with variations of hydrothermal time and its use for methylene blue adsorbent has been done. The hydrothermal process was carried out at the temperature of 200˚C for 3 hours, 6 hours, and 12 hours. The characterization of hydrochar substrate using FTIR (Fourier Transform Infrared Spectroscopy) showed the decrease in absorption intensity of 47% and a shift in several wavenumbers. The characterization using SEM (Scanning Electron Microscope) showed that there are morphological changes on the surface of the hydrochar become to more holes after the hydrothermal process. The optimum condition for adsorption occurred at pH 7 for 10 minutes. The adsorption capacity of methylene blue increased from 44.70 mg/g to 45.82, 46.17, and 46.90 mg/g after hydrothermal process. The results also showed that the adsorption followed the Freundlich isothrm which showed a tendency for multilayer interactions on the surface of the galam barks after the hydrothermal process.

Abstract: Sago bark biomass waste was modified into biochar through pyrolysis with temperature variations of 500 ℃, 600 ℃ and 700 ℃ for 2 hours to increase the adsorption capability. This research aims is to know the adsorption isotherm model of methylene blue on sago bark biochar. The results showed that the adsorption capability of biochar increased comparing to the adsorption capability sago bark without pyrolysis process dan reached optimum adsorption condition at pH 9 for 10 minutes. The results of the analysis show that the adsorption of methylene blue on biochar is closer to the Freundlich isotherms model than to the Langmuir isotherm model. The adsorption capacity of methylene blue on pyrolysis biochar at temperature of 500 ℃, 600 ℃, and 700 ℃ respectively were 45,86; 46,22 and 46,90 mg/g.Abstrak: Limbah biomassa kulit sagu dimodifikasi menjadi biochar melalui pirolisis dengan variasi suhu 500 ℃, 600 ℃, dan 700 ℃ selama 2 jam untuk memperbaiki kemampuan adsorpsinya.

This research aims to evaluate the suitability of sago palm waste as a fiber raw material in terms of its chemical content and anatomical characteristics. The chemical content analysis of its extractive components, lignin, holocellulose, α-cellulose, and hemicellulose, was carried out using sago frond powder with a size of 40–60 mesh. Subsequently, functional group analysis was performed using Fourier Transform Infra-Red (FTIR), while anatomical characterization was carried out by calculating the fiber length and diameter, lumen diameter, fiber derivative values, and wall thickness using a microscope connected to a digital camera. Scanning Electron Microscope (SEM) pictures were taken in different magnifications. The results showed that sago frond contains 31.6% α-cellulose and 38% lignin. The α-cellulose content was within the standard range for non-timber forest products, but the lignin content had a relatively high value. Based on the derived value, namely class II, sago frond can be used as pulp and paper raw materials.
