Abstract

Due to the rising demand for motor vehicle fuel, Indonesia's requirement for fossil fuels rises by an average of 10% annually. The supply of fossil energy, which serves as the primary raw material for generating fuel oil, is negatively correlated with the demand for fuel (BBM). Fresh Fruit Bunches (FFB), Empty Fruit Bunches (EFB), and fiber were the types of oil palm bunches employed in this investigation. EFB and fiber are industrial by products that are currently being used inefficiently and frequently pollute the environment. This trash is still only very minimally processed; it is still stored, burned in the incinerator, used as mulch on oil palm fields, and composted. 51.2 percent cellulose and 16.30 percent lignin are both present in EFB. Lignin makes up 20.0 percent of fiber, whereas cellulose makes up 57.0 percent. Through chemical and enzymatic procedures, this cellulose content may be exploited as a source of reducing sugars. FFB is used as a benchmark to evaluate how effectively the prototype tool works. Different kinds of high-quality bioethanol are produced from each raw source. Different kinds of high-quality bioethanol are produced from each raw source. Fresh Fruit Bunches (FFB), which have a refractive index of 1.35676 and a volume of 2,192 ml, are the best quality of bioethanol made from raw materials. The findings demonstrated that varied volumes and refractive indices were produced depending on how raw materials were treated. The quality generated improves with increased treatment volume. Alkaline delignification was followed by acid delignification to get the optimum grade. Empty Fruit Bunch (EFB) material, which had a refractive index of 1.34376, 2,105 ml of bioethanol, and a 68.15 percent ethanol concentration. This study is unique in that it includes a bioethanol trap to quicken the conversion of steam into liquid bioethanol. Condensation is completed in 15–20 minutes less time thanks to the bioethanol trap.

Abstract

ABSTRAK Hidrogen merupakan salah satu sumber energi potensial yang berkelanjutan dan bersih dengan kepadatan energi tinggi (140 MJ/kg). Abu berat merupakan limbah padat yang sulit larut dan menguap serta memerlukan pengolahan khusus. Pembakaran batubara di PLTU menghasilkan limbah berupa fly ash dan bottom ash dalam jumlah besar setiap tahunnya, yang berpotensi mencemari lingkungan jika tidak dimanfaatkan dengan tepat. Pada tahun 2021, Indonesia menghasilkan sekitar 9.7 juta ton limbah abu terbang (fly ash dan bottom ash). Tujuan dari penelitian ini adalah memanfaatkan kandungan 53-70 Si pada abu terbang untuk meningkatkan gas hidrogen dengan menambahkan zat pereduksi aluminium dan memvariasikan konsentrasi katalis KOH. Katalis KOH digunakan karena KOH menghasilkan lebih banyak gas hidrogen dibandingkan NaOH. Penelitian ini dilakukan dengan mereaksikan 3 sampai 6 gram aluminium: silikon dengan air suling dan katalis KOH 4,5 M - 5M dan ini dilakukan pada temperatur 50°C selama 15 menit. Dengan berat auminium:silicon 6 gran dan konsentrasi KOH 5.5 M menghasilkan produksi gas hydrogen sebesar 68%. Semakin banyak penggunaan aliminium:silikon dan semakin tinggi konsentrasi KOH yang digunakan maka gas hidrogen yang dihasilkan akan semakin banyak. Kata kunci: Aluminium, bottom ash batubara, hidrogen, silikon ABSTRACT Hydrogen is a potential sustainable and clean energy source with a high energy density (140 MJ/kg). Heavy ash is a solid waste that is difficult to dissolve and evaporate, requiring special treatment. In 2021, Indonesia produced approximately 9.7 million tons of fly ash and bottom ash. This study aims to utilize the 53–70% Si content in fly ash to enhance hydrogen gas production by adding aluminum as a reducing agent and varying the concentration of KOH catalyst. KOH was selected as the catalyst because it generates more hydrogen gas compared to NaOH. The experiment was carried out by reacting 3 to 6 grams of aluminum:silicon with distilled water and KOH catalyst at concentrations ranging from 4.5 M to 5 M, maintained at 50°C for 15 minutes. The highest hydrogen gas production of 68% was obtained with 6 grams of aluminum:silicon and a KOH concentration of 5.5 M. The results showed that increasing the amount of aluminum:silicon and the concentration of KOH led to greater hydrogen gas generation. Keywords:  Aluminum, coal bottom ash, hydrogen, silicon

Abstract

Peat water is surface water or ground water which is found abundantly in tidal, swampy and lowland areas. It has a reddish-brown color, with an acerbic taste (high acidity), and has a high organic content. Peat water can be treated using the adsorption method. Adsorption is a physical phenomenon in which the molecules of the adsorbed material are attracted to a solid surface, which acts as an adsorbent. In this study, the authors used the adsorption method to reduce the color concentration of peat water using activated chicken bones powder as an adsorbent and observing the changes that occur when mass of powder to the amount of 0.1, 0.2, 0.3, 0.4, 0.5, 1.0, 1.5 and 2.0 grams were added to 50 ml of peat water with contact time that varied from 20, 30, 40, 50 and 60 minutes. From this study, we conclude that the optimum yield was obtained when the mass and contact time were at 0.5 grams and 40 minutes, which yield a percentage of reduction of 95.59%, wherein the initial color concentration of peat water at 337.816 was reduced to 14.89 Pt-Co, which is in line with the standard color for clean water as specified in a Regulation by the Minister of Health of the Republic of Indonesia No. 492/MENKES/PER/IV/2010, which state the standard color for clean water is 15 Pt-Co.

Abstract

One of Indonesia's greatest waste crops, rice husk, has not yet been fully exploited. Rice husk has a high lignocellulose content, increasing its potential as a renewable energy source, particularly in the form of biopellets. The procedure of creating biopellets is the focus of this study. biopellets made from rice husk and evaluate their quality using proximal, ultimate, value, density, and heat criteria. The study's stages include drying the raw material, milling it to a uniform size, using a pellet mill for pelletisation, and testing the biopellets for quality in compliance with SNI 8951:2020. The study's findings revealed that rice husk biopellets have sufficient calories and low water content after undergoing optimal drying. However, the high relative ash content is the main problem in using it as a feedstock for co-firing, necessitating quality enhancement through chemical treatment or blending with other biomass. Overall, biopellets derived from rice husks have the potential to serve as an environmentally acceptable and cost-effective alternative energy source for household and industrial use.

Abstract

This research investigates the effectiveness of a Diethanolamine (DEA) promoted potassium carbonate (K₂CO₃) solution for capturing carbon dioxide (CO₂) from flue gas generated by the carbonization of coconut shells. The study aimed to evaluate the influence of absorption column packing height and absorbent flow rate on CO₂ removal efficiency. The absorption process was conducted in a counter-current packed column using a solution composed of 30% wt K₂CO₃ and 3% wt DEA. Key process variables included packing heights of 10, 20, 30, and 40 cm, and absorbent flow rates of 0.5, 1.0, and 1.5 L/m. The results demonstrated that the combined DEA and K₂CO₃ solution is highly effective, achieving a maximum CO₂ removal efficiency of 97.81% at a packing height of 40 cm and a flow rate of 1.5 L/m. Analysis of the absorbent solution revealed a corresponding decrease in carbonate (CO₃²⁻) concentration and an increase in bicarbonate (HCO₃⁻) concentration, confirming the chemical absorption of CO₂. The process kinetics were found to align with a pseudo-second-order model. This study concludes that a packed column absorption system with a DEA-promoted K₂CO₃ solution presents an effective and viable method for mitigating CO₂ emissions from biomass processing.
