The production volume or amount of Acacia wood used is generally low compared to thevolume of wood harvested. Not a few woods that are cut cause wood harvesting wastesuch as branches and twigs. One of the uses is processing the waste into activatedcharcoal. Activated charcoal is charcoal whose cavities or pores are cleaned from othercompounds so that the adsorption power of liquids and gases increases. This researchuses the Acacia wood of the stem, branches and twigs which is first through thecarbonization process and then used as activated charcoal. The active charcoal testsinclude yield, moisture content, volatile matter content, ash content, carbon boundcontent, absorption of benzene, absorption of iodine and absorption of methylene blue.Acacia quality test results of the stem, branches and twigs show that the activatedcharcoal of the stem has better quality than the active charcoal of branches and twigs.Overall the results of testing the quality of activated charcoal not all treatments meet therequirements of SNI 06-3730-1995, but when compared with the requirements of thequality of pharmaceutical chemistry, all tests for each treatment meet the qualitystandard requirements. The application of activated charcoal to drilled well water doesnot all improve water quality but still qualifies the drinking water quality standardsMinister of Health Regulation No: 416/Menkes/Per/IX /1990.Keywords: Active Charcoal, Acacia, Trunk, Branches, Branches, Drilling Well Water

Abstract Bambusa blumeana BI. Ex. Schult. F. is a non-timber forest product used as building material by the people of Lombok. The utilization of bamboos leaves their branches as a waste that has not fully utilized. One way to take advantage of this waste is to use it as a raw material to make activated charcoal. The purpose of this study was to determine the effect of variations activation temperature, the concentration of phosphoric acid (H3PO4), as well as interactions between variations of the activation temperature and the concentration of phosphoric acid (H3PO4) on the quality of activated charcoal of B. blumeana branch. This study employed a factorial completely randomized design (RAL) with two (2) factors. The first factor (A) was activation temperature i.e. 600oC (A1), 700oC (A2), and 800oC (A3), meanwhile the second factor (B) used the concentration of phosphoric acid (H3PO4), namely 10% (B1) and 20% (B2). The results showed variations in the activation temperature significantly affected the yield and iodine adsorption. Based on the results, the best treatment was obtained at a temperature of 700oC with an H3PO4 concentration of 10% (A2B1) with the yield value of 76.04%, moisture content of 2.12%, volatile matter content of 32.70%, ash content of 8.15%, fixed carbon content of 59.15%, and sodium adsorption of 599.63 mg/g. Abstrak Bambu duri (Bambusa blumeana BI. Ex. Schult. F.) merupakan hasil hutan bukan kayu yang dimanfaatkan sebagai bahan bangunan oleh masyarakat Lombok. Pemanfaatan bambu tersebut meninggalkan limbah cabang yang belum dimanfaatkan secara maksimal. Salah satu pemanfaatannya adalah menjadi arang aktif. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi suhu aktivasi, konsentrasi asam fosfat (H3PO4), serta interaksi antara variasi suhu aktivasi dan konsentrasi asam fosfat (H3PO4) terhadap karakteristik arang aktif cabang bambu duri (B. blumeana). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor, faktor pertama (A) menggunakan suhu aktivasi yaitu 600oC (A1), 700oC (A2), dan 800oC (A3), sedangkan faktor kedua (B) menggunakan konsentrasi asam fosfat (H3PO4) yaitu 10% (B1) dan 20% (B2). Hasil penelitian ini menunjukkan bahwa variasi suhu aktivasi berpengaruh nyata terhadap nilai rendemen dan daya serap iod. Berdasarkan hasil pengujian, perlakuan terbaik diperoleh pada suhu 700oC dengan konsentrasi H3PO4 10% (A2B1) yang menghasilkan nilai rendemen sebesar 76,04%; kadar air 2,12%; kadar zat terbang 32,70%; kadar abu 8,15%; kadar karbon terikat 59,15%; dan daya serap iod 599,63 mg/g.

Abstract- A research on the utilization of ulin wood waste (Eusideroxylon Zwageri T) has been conducted as an active charcoal to adsorb Iron (Fe) and Manganese (Mn). The purpose of this research is to know and study the potential of activated charcoal from Ulin wood waste as adsorbent of Iron (Fe) and Manganese (Mn) in well water, knowing optimum time to adsorb Iron (Fe) and Manganese (Mn) and to know the concentration of Iron (Fe) and Manganese (Mn) after adsorbed by activated charcoal from Ulin wood waste. Charcoal is obtained from Ulin wood with burning for 9 hours, then activated chemically and physics. The parameters studied were pH, optimum time determination, Iron (Fe) and Manganese (Mn) concentration after adsorption. The results showed that the optimum time (toptimum) to adsorb Iron (Fe) and Manganese (Mn) was at minute 30 and obtained the optimum concentration of Iron (Fe) of 0,22 mg / L and Manganese (Mn)  concentration of 0,174 mg / L . Keywords: Ulin Wood, activated charcoal, Fe and Mn adsorption, filtration.

AbstractThe present work analyzed the energy generation potential of Buriti (Mauritia flexuosa L. f.) by thermochemical reactions. The experimental part of the study performed immediate analyses, elemental analyses, lignocellulosic analysis, thermogravimetric analysis, calorific values, and syn gas concentrations measurements of the gasification of Buriti in a fixed-bed reactor. Additionally, numerical simulations estimated the syn gas concentrations of the gasification reactions of Buriti. The immediate analysis showed that Buriti has the highest ash content (4.66%) and highest volatile matter content (85%) compared to other Brazilian biomass analyzed, but the higher heating value was only 18.28 MJ.kg−1. The elemental analysis revealed that the oxygen to carbon ratio was 0.51 while hydrogen to carbon ratio was 1.74, indicating a good thermal conversion efficiency. The Lignocellulosic analysis of Buriti resulted in a high content of holocellulose (69.64%), a lignin content of 28.21% and extractives content of 7.52%. The thermogravimetry of the Buriti indicated that the highest mass loss (51.92%) occurred in a temperature range between 150 °C and 370 °C. Lastly, the experimental gasification study in a fixed-bed updraft gasifier resulted in syn gas concentrations of 14.4% of CO, 11.5% of CO2 and 17.5% of H2 while the numerical simulation results confirmed an optimal equivalence ratio of 1.7 to maximize CO and H2 concentrations. Therefore, based on the results presented by the present work, the gasification process is adequate to transform Buriti wastes into energy resources. Graphic abstract
