Abstract

Oil palm bunches Empty fruit bunches are the main lignocellulosic solid waste that has not been optimally utilized, so many empty bunches are not processed. Unprocessed EFB causes a foul odor and becomes a place for flies to nest. Thus, it is considered as waste that pollutes the environment. Adsorption is a popular new method to reduce heavy metal content and waste in water, in addition the adsorption method is also effective and efficient in terms of the absorption process, and can also be a regeneration adsorbent. This study began with the preparation of empty oil palm bunches which were then carbonized and activated with H3PO4, then synthesized with MOFs-Cu(TAC). The final stage was tested for absorption by optimizing mass and time. The XRD pattern shows sharp peaks that appear on the graph indicating metal contact and the KA-Cu(TAC) composite has a good and regular crystal structure. The KA-Cu(TAC) composite has great potential as an alternative adsorbent to improve the quality of palm oil because it has good absorption.

Abstract

The rapid expansion of oil palm plantations in North Sumatra, from 31,730,961 hectares in 2016 to 41,667,011 hectares in 2018, has resulted in significant solid waste generation, particularly empty fruit bunches (EFB). This study aims to utilize EFB as a precursor for activated carbon production and evaluate its effectiveness in adsorbing beta-carotene from crude palm oil (CPO). EFB was processed through carbonization and activation to create a composite adsorbent KA-Fe(TAC) synthesized with metal-organic frameworks (MOFs). Characterization using X-ray diffraction (XRD) confirmed the crystalline structure of the composite. Results indicated that the optimal adsorption efficiency for activated carbon was 8.925%, while the KA-Fe(TAC) composite achieved 21.645%. The findings suggest that the KA-Fe(TAC) composite significantly enhances beta-carotene adsorption capacity compared to conventional activated carbon. Additionally, the optimal contact time for adsorption was found to be 60 minutes for activated carbon and 150 minutes for the KA-Fe(TAC) composite, indicating improved efficiency over time.
