This research paper presents the preparation and characterization of activated charcoal derived from palm coir (Borrassus flabellifer L.) that was activated using potassium hydroxide (KOH). The objective of this study was to assess the key characteristics of the activated charcoal, including moisture content, ash content, and surface area, and to determine the optimal conditions for the adsorption process of Rhodamine B dyes, such as adsorbent mass, contact time, and adsorbate concentration. Additionally, the surface morphology of coir charcoal before and after activation was investigated. The carbonization process was conducted at 300°C for 30 minutes, followed by activation using 1 M KOH for 24 hours. The resulting activated charcoal was subjected to various characterization techniques, including moisture content and ash content analysis, surface morphology examination using scanning electron microscopy (SEM), surface area determination using the Brenauer-Emmet-Teller (BET) method, and functional group identification through Fourier-Transform Infra Red (FTIR) spectroscopy. The findings revealed that the activated charcoal exhibited a water content of 1.537%, an ash content of 16.653%, and a surface area of 36.084 m2/g. The optimal conditions for the adsorption process were determined as follows: 1.0 gram of activated charcoal mass, 30 minutes of contact time, and a rhodamine B concentration of 30 ppm, resulting in adsorption efficiencies of 94.46%, 95.75%, and 94.42%, respectively. Furthermore, the surface morphology analysis demonstrated that non-activated charcoal exhibited irregular particle sizes and small pore sizes, while KOH-activated charcoal displayed an enhanced carbon pore surface and larger pore sizes.

“…Hal itu dimungkinkan karena pada saat pembilasan dengan akuades, karbon aktif dengan aktivasi asam fosfat 8M lebih banyak terkontak dengan akuades dibanding yang lain sehingga kadar air menjadi lebih tinggi. Tujuan dari pengukuran nilai kadar air ini adalah untuk mengetahui kemampuan higroskopis dari karbon aktif [17] .…”

Rice husk is an organic material that has a high lignocellulosic content so it has the potential to be turned into activated carbon. One method of making activated carbon is activation with a phosphoric acid activator (H3PO4). The purpose of this research was to study the effect of varying concentrations of H3PO4 as an activator on the characteristics of rice husk-activated carbon. The characterization refers to SNI 06-3730-1995 regarding the technical quality requirements of activated charcoal. Activation of rice husk carbon was carried out by contacting the carbon with H3PO4 for 24 hours and shaking it. The H3PO4 consisted of 3 concentration variations, namely 4M, 6M, and 8M. From the research results, the water content was 3.936%; 4.037%; 4.070%, the absorption of iodine has met the character of activated charcoal according to SNI, namely 1217.204 mg/g; 1204.255 mg/g; 1184.832 mg/g while the ash content value does not meet the SNI standard, which is still above 10%. The highest adsorption capacity and adsorption efficiency could be activated with 8M H3PO4, namely 22.42 mg/g and 89.68%. IR spectra on activated carbon with three variations of H3PO4 concentration showed the presence of aromatic C-H, C=C, and C-O anhydride functional groups.
