“…The carbon of the palm kernel shell before activation still contains tar and other substances, so that the ashing process produces a higher ash content. The resulting volatile matter content (14.31%) is in accordance with the results of previous studies using activated carbon of 100 mesh palm kernel shells and 5% H3PO4 activated [20]. Measurement of volatile matter content on activated carbon of palm kernel shells activated by NaOH with a carbonization temperature of 400 -600 o C obtained volatile matter levels of 10 -15% [26].…”

One method to reduce the content of heavy metal mercury in wastewater is adsorption. Several media materials have been investigated for use as adsorbents. In this study the characteristics of the palm kernel shell were analysed so that it could be used as an adsorbent. In addition, it also analysed its ability to reduce levels of mercury in wastewater. Palm kernel shells were activated using two types of activators, namely H3PO4 and NaOH and variations in adsorbent sizes of 50 mesh and 100 mesh, as well as variations in contact time for 30 and 60 minutes. Based on the results of this study, it was obtained that the characteristics of the adsorbent of palm kernel shells with the use of H3PO4 and NaOH activators met the quality based on SNI 06-330-95. The adsorption efficiency of mercury (Hg) removal can reach 99.7% with a contact time of 60 minutes and an adsorbent size of 100 mesh activated by NaOH.

“…A previous study conducted by Hendra reported that the highest quality absorbent could be made from palm kernel shell at a temperature of 850 o C [8]. In order to increase the adsorbent's adsorption capacities and efficiency, chemicals including phosphate acid (H3PO4) [9], chloric acid (HCl) [10], sodium hydroxide (NaOH), and potassium hydrogen oxide (KOH) [11] have also been used in the activation process. Specifically, H3PO4 activator has shown the ability to effectively produce chemical reactions in the synthesis of organic compounds [12], increasing final product yield to ensure better adsorption with enhanced physical and chemical stability.…”

Palm kernel shell is solid waste produced from the processing of crude palm oil (CPO). In this context, phosphoric acid (H3PO4) serves as an essential activator for producing an adsorbent with maximum micropore under operating conditions at a temperature of <450oC. Therefore, this study aimed to determine the optimal adsorbent condition of the palm kernel shell using H3PO4activator. The production process was optimized using Response Surface Methodology (RSM) and Central Composite Design (CCD) methods with activator concentration variations of 4%, 5%, and 6%, at activation times of 23 hours, 24 hours, and 25 hours, respectively. The quality of the adsorbent produced fulfilled SNI standard 06-3730-1995, characterized by water content of 1.001%, ash content of 5.767%, missing substance level of 18.932%, and fixed carbon content of 75.301%. Furthermore, this work effectively optimized the RSM and CCD adsorbent production process, achieving 4.785% variation in activator concentration and 24.679 hours activation time.

Abstract. Acid mine water is water that has a low pH (pH<5) which contains various dissolved metals such as iron (Fe), manganese (Mn), and other sulfate compounds. Acid mine water has an impact in the form of environmental pollution, so it is necessary to handle Acid Mine Drainage using activated carbon so that it does not affect the surrounding environment. The research method used in this study is the active method by mixing activated carbon into 6 settling ponds, it aims to be able to determine the effect of activated carbon on settling ponds in the form of pH and Fe and Mn levels based on standard water quality standards.The rate of decrease in Fe metal content and Mn metal content after mixing using activated charcoal was 76,0% for Fe metal content and 18,60% for Mn metal content. The need for activated carbon for 31 days for the purpose of neutralizing acid mine water is 154790,8 kg/liter. Abstrak. Air asam tambang merupakan air yang memiliki pH rendah (pH<5) yang mengandung berbagai logam terlarut seperti besi (Fe), mangan (Mn), serta senyawa sulfat lainnya. Air asam tambang menimbulkan dampak berupa terjadinya pencemaran lingkungan sehingga perlu dilakukannya penanganan air asam tambang dengan menggunakan Karbon aktif sehingga tidak mempengaruhi lingkungan sekitar. Metode penelitian yang digunakan pada penelitian ini yaitu metode aktif dengan cara mencampurkan Karbon aktif kedalam 6 kolam pengendapan, hal tersebut bertujuan untuk dapat mengetahui pengaruh karbon aktif pada kolam pengendapan berupa pH serta kadar Fe dan Mn dengan berdasarkan standar nilai baku mutu air. Laju penurunan kadar logam Fe dan kadar logam Mn setelah pencampuran dengan menggunakan Karbon aktif yaitu sebesar 76,0% untuk kadar logam Fe dan 18,60 % untuk kadar logam Mn. Kebutuhan karbon aktif selama 31 hari untuk keperluan penetralan air asam tambang sebesar 154790,8 kg/liter.
