Analisis Kandungan Lignin, Sellulosa, dan Hemisellulosa Serat Sabut Kelapa Akibat Perlakuan Alkali

Abstract

The long-term goal of this research is to makecoconut fiber composite as one of the technical material, forbuilding material such as ceiling board or for automotivematerial such as bumper. While the specific target to be achievedin this research is to determine the influence of the concentrationof alkali solution on soaking coconut fiber to the content of lignin,cellulose, and hemicelluloses of coconut fiber. To achieve theobjectives and targets, the method of implementation of thisresearch is divided into 4 (four) steps, namely (1) preparation, (2)immersion, (3) testing, and (4) analysis. Coconut fiber is treatedby soaking coco fiber for 3 hours in sodium hydroxide (alkali)solution with concentrations of 5%, 10%, 15%, 20%, 25%, 30%,35%, 40%, 45%, 50%, and 55%. Once soaked, the coconut fiberis rinsed with aqua, then dried in an oven at 60°C for 4 hours.After that, a composition test with hydrolysis method todetermine the content of lignin, cellulose, and hemicelluloses.Each variable will be tested 3 (three) times. The data obtainedwill be analyzed statistically by applying descriptive method,where all data obtained will be presented in table, graphic, orimage form. Based on the tables, graphs, and images will beanalyzed and drawn conclusions. The results to be achieved inthis study is to determine the content of lignin, cellulose, andhemicelluloses coconut fiber due to alkali treatment for 3 hourswith a variable concentration of alkali solution. Based on theresults and discussion it can be concluded that soaking coconutfiber in alkaline solution degrades the content of hemicelluloses,cellulose and lignin.

Pemanfaatan Sabut Kelapa Sebagai Bioadsorben Logam Berat Pb(II) Pada Air Limbah Industri

“…Pada umumnya sabut ini dimanfaatkan sebagai kayu bakar [19]. Struktur sabut kelapa tersusun atas selulosa 37,9%, lignin 33,5%, dan hemisellulosa 15,5% [31]. Secara alami, sabut kelapa akan memberikan struktur berpori, sehingga dapat digunakan sebagai bioadsorben tanpa pengarangan.…”

Kinetic Study of Blue Methylene Adsorption Using Coconut Husk Base Activated

“…In addition, alkali treatment or base activated can cause damage to the lignin structure, cellulose, and hemicellulose, decreasing adsorption at high pH. The most considerable adsorption occurred at 7 of solution pH because a balance of H + and OHions amount in the solution did not affect the interaction between active sites in the solution and the adsorbent (Kondo & Arsyad, 2018).…”

Effect of Delignification Process on Cellulose, Hemicellulose, and Lignin Content on Liquid Glucose Production from a Mixture of Corn Cobs (Zea mays) and Sugar Cane Bagasse (Saccharum officinarum)

“…Making bioethanol is quite affordable because the raw materials are plentiful and easy to find in everyday life [3]. Corn cob [4] and bagasse [5] can be utilized because it contains a lot of lignocellulose, cellulose, hemicellulose, and lignin [6]. Lignocellulose can become glucose because cellulose forms straight and branched chains from a combination of glucose by releasing water [6].…”

Lignocellulose can become glucose because cellulose forms straight and branched chains from a combination of glucose by releasing water [6]. Extraction of materials is possible from sugarcane and sweet corn wastes, which are thrown away due to a lack of understanding about their processing and utilization.…”
