Abstract

Durian peel is one of the agricultural wastes that has not been utilised optimally and has the potential to be used as an alternative to biomass-based activated carbon. This study was conducted to study the optimisation process of making activated carbon from durian peel using H3PO4 activator. The optimisation process was carried out using Response Surface Methodology (RSM) to optimise the variables that affect the quality of activated carbon using the Box-Behnken method. The variables used were 20% v/v, 25% v/v, and 30% v/v H3PO4 concentrations, activation time of 12 hours, 24 hours, and 36 hours, weight ratio of activated carbon to H3PO4 activator 1:2 m/v, 1:3 m/v, and 1:4 m/v. The optimization using RSM method results showed an iodine absorption capacity of 790.139 mg/g obtained under the following conditions, H3PO4 concentration of 30% v/v, activation time of 34.78 hours, and weight ratio of activated carbon to H3PO4 activator of 1:4 m/v. Activated carbon from durian peel with optimum conditions obtained surface area value of 2.407 × 10-11 m2 and activated carbon diameter of 4.878 μm using Scanning Electron Microscopy (SEM) analysis test

Abstract

Petroleum is one of the energy sources that currently has very wide uses. In addition to the fact that petroleum is a non-renewable resource, the use of fuel oil has also affected emission levels. Biofuel is an alternative fuel in solid, liquid or gas form that can be obtained from animals, plants, or agricultural waste. The process of making biofuel can be done by several methods, namely by thermal cracking, hydrocracking, and catalytic cracking. Thermal cracking is a simple process where heat is used to cut long hydrocarbon chains. Catalytic cracking is the process of breaking hydrocarbon chains using a catalyst. This study aims to determine the effect of Mg(OH)2/γ-Al2O3 catalyst (2 and 6)% and to determine the effect of the ratio of Mg(OH)2/γ-Al2O3 catalyst (1, 2, 3 and 4)% on the yield and selectivity of biofuel products from catalytic cracking of palm oil. The process of making biofuel through catalytic cracking process using Mg(OH)2/ γ –Al2O3 catalyst as much as 1% of the volume of material with a temperature of 370℃ on a hotplate magnetic stirrer and reactor for ±3 hours. The biofuel results were analyzed by Gas Chromatography Mass Spectrophotometry (GCMS). The highest biogasoline was obtained using Mg(OH)2/γ-Al2O3 catalyst 2% with a ratio of 2% which was 16.6%. While the highest biodiesel was obtained using Mg(OH)2/γ-Al2O3 catalyst 6% with a ratio of 2% which was 42.7%.

Abstract

National salt production capacity is dominated by smallholder salt production through the crystallization process in traditional salt ponds. One of the salt producing areas in South Sulawesi Province is located in Jeneponto Regency. Salt farmers in Jeneponto Regency produce salt through traditional salt ponds. Jeneponto Regency is also one of the main coconut producing areas. Coconut coir from the people's plantation industry is currently only used as fuel in small and medium home industries or is simply thrown away as waste. Coconut coir has the ability to absorb water. The aim of this research is to innovate the use of coconut coir waste to increase the surface area for water evaporation in traditional laboratory-scale salt ponds. This research was also carried out by conducting analysis on traditional ponds to study the factors that influence the salting process. Next, the salting process was carried out on a laboratory scale by making a replica of the traditional pond salting process which was equipped with the addition of coconut coir to increase the evaporation surface area. The results of the research show that the salting process in traditional salt ponds is greatly influenced by the season. The sun plays a very important role in the evaporation process in traditional salt ponds until salt crystals form in the ponds. Laboratory scale salt pond equipment shows that the use of coconut coir plays a very important role in speeding up the evaporation process and has the potential to increase salt production in traditional salt ponds.

Abstract

Sugarcane bagasse (Saccarum officinarium) is a byproduct of the sugar production process and holds potential as a raw material for bioethanol production due to its lignocellulose content. Lignocellulose contains important components such as cellulose, hemicellulose, and lignin. This study focuses on the delignification of sugarcane bagasse (Saccarum officinarium) through a combination of mechanical and autoclave treatments, with variations in particle size and heating time. The goal of this study is to reduce the lignin content and increase the proportion of cellulose and hemicellulose, key components for producing valuable products  for instance bioethanol. In this research, sugarcane bagasse was processed with particle sizes of 60, 70, and 80 mesh, and heated in an autoclave for 30, 45, and 60 minutes. The Chesson-Datta method was used to analyze the lignocellulose content of the bagasse after the delignification process. The results showed that the best outcome was achieved with a particle size of 80 mesh and a heating time of 60 minutes, yielding the lowest lignin content at 14.27%, while cellulose and hemicellulose reached 44.3% and 26.75%, respectively. This indicates that variations in particle size and heating duration significantly affect the effectiveness of the delignification process. Optimizing these two parameters is crucial for increasing cellulose and hemicellulose content while reducing lignin. Further research is expected to develop more effective pretreatment techniques to enhance the efficiency of sugarcane bagasse biomass conversion for industrial applications

Abstract

Empty Oil Palm Bunches (EOPB) are waste products from palm oil mills, the waste is produced in large quantities, but most palm oil mills have not utilized this waste product adequately. There are several contents of EOPB, namely cellulose, hemicellulose and lignin, each of which has economic value so that it can be utilized further. One significant opportunity is that cellulose in EOPB will be converted into glucose or bioethanol. Bioethanol is one of the options in supporting the availability of renewable energy resources. The bioethanol production process consists of initial pretreatment, hydrolysis, fermentation and purification. The delignification process of Empty Oil Palm Bunches (EOPB) using physical and chemical pretreatment can break down lignin and hemicellulose so that cellulose can be converted into glucose in bioethanol production. The pretreatment procedure with H2SO4 solvent is used to increase cellulose content. The purpose of this study was to determine how different concentrations of H2SO4 affect the amount of cellulose in the EOPB pretreatment process. Additional studies on bioethanol can be done with this cellulose content. There is an experimental component in this study, namely through direct observation and testing of materials containing different concentrations of H2SO4, namely 3%, 5%, and 7%, data were collected through laboratory experiments. The cellulose content for 0% H2SO4 concentration was 16.15%, 3% H2SO4 was 30.00%, 5% H2SO4 was 36.35%, and 7% H2SO4 was 41.09% indicating that the H2SO4 solvent can increase the cellulose content.

Abstract

The use of disposable face masks can reduce the transmission of Covid-19 through saliva splashes from infected patients. However, the use of these masks causes waste generation that has the potential to release microplastic fibers into the environment. Biodegradation by freshwater microalgae can be a solution to handling disposable face mask waste. Microalgae were isolated from retention ponds in Institut Teknologi Sumatera using Walne fertilizer and pineapple liquid waste (LCN) as alternative growth media. Selected isolate was used to degrade three-ply mask pieces with Walne:LCN media ratios of 1:0,; 0:1, and 1:1 as well as Walne media without the addition of isolate as a control. Analysis of the masks degradation results was carried out using gravimetric and Fourier Transform Infraredmethods. Gravimetric analysis showed a decrease in mask mass after degradation for the control, 1:0, 0:1, 1:1 treatments, which were 0.0004grams, 0.0054grams, 0.0088grams and 0.0193grams, respectively. FTIR analysis showed new functional groups (O-H), increased C=C, and decreased C-H % transmittance of the masks after degradation. It can be concluded from the analysis that microalgae isolated from ITERA’s retention basin was able to degrade disposable masks, which is characterized by a decrease in mask mass and changes in % transmittance of C=C and C-H functional groups. The addition of LCN did not show a significant effect on mask degradation compared to variations without LCN, as evidenced by the FTIR results in the 1:1 variation where no alkene groups appeared and the alkyl group spectrum peaks were not much different from the control

Abstract

Paper waste is one type of waste that is quite abundant. Effective processing of paper waste can be done using hydrolysis process because this process can decompose lignocellulose compounds in paper waste into simpler compound such as glucose and other derivative products. Hydrolysis process was generally carried out using chemical catalysts such as acids, bases and enzymes. In this study, paper waste hydrolysis was investigated using base catalysts such as potassium hydroxide (KOH) from palm oil empty fruit bunches (POEFB) ash and commercial KOH. The research stages began with the preparation of POEFB ash, KOH production from POEFB ash, paper waste preparation, and the hydrolysis process of paper waste using KOH from POEFB ash and commercial KOH. This study uses variations in hydrolysis time were carried out to evaluate the hydrolysis conversion. Based on the research, it was showed that KOH catalyst from POEFB ash contain potassium compounds in the form of 5.87% potassium oxide (K2O) and 31.45% potassium carbonate (K2CO3). Comparison of catalyst performance between KOH catalyst from POEFB ash and commercial KOH catalyst showed that commercial KOH catalyst was better than KOH catalyst from POEFB ash. The effect of hydrolysis reaction time was directly proportional to the conversion value that the highest conversion was 12.11% at 90 minutes using commercial KOH catalyst.

Abstract

Shallots are an important food commodity for the needs of various Indonesian cuisines and other uses that are widely utilized. However, currently shallot farmers complain about post-harvest shallots that are easily damaged such as rotting, wrinkling, porous, root growth and fungal growth. To reduce this damage, preservation is needed. One alternative technology is Co-60 Gamma Ray Irradiation based on the principle of electromagnetic radiation that produces high-energy photons that cause ionization and excitation in the material it passes through. The nature of Gamma rays used in the preservation process has great penetrating power and does not cause temperature changes in the irradiated food. The purpose of this study was to determine the effect of Co-60 gamma ray irradiation on the optimization of the shelf life of post-harvest preservation of shallots with variations in control doses: low, medium and high, variations in temperature and quality parameters. The method of this research stage is: 1) Sample preparation. 2) Gamma Ray Irradiation of Co-60 with variation of control dose: low, medium and high 3) Analysis of temperature measurement and measurement of quality parameters (water content, weight loss, damage and hardness) against the irradiation dose. The results showed that gamma ray irradiation of Co-60 affected the length of shoots based on variation of dose and temperature, namely on day 1 and day 14 the combination of 650Gy treatment at 350C had the smallest shoot length, water content was relatively high, weight loss was relatively small, damage was relatively small and hardness was relatively high.

Abstract

Household liquid waste, which is rich in organic matter such as detergents and food waste, is one of the main causes of water and soil pollution. Household waste contains organic substances that pollute water and soil. Moringa seeds, as a natural coagulant, effectively bind suspended particles in water to be clean and safe for the environment. Moringa seeds, with their high protein content, act as a natural coagulant that is effective in settling pollutants in water. In addition, moringa seeds are rich in polar groups which have been proven to be effective as natural coagulants in lowering pH, Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) in liquid waste. This study aims to analyze the chemical parameters of the influence of moringa seeds on pH changes, decrease in BOD and COD levels in household liquid waste. In this study, liquid waste samples obtained from households around Banta Bantaeng, Rappocini Village, Makassar City were used. The chemical parameters analyzed include pH, BOD, and COD. The research was conducted using the jar test method to measure parameter changes before and after the coagulation process. The concentration of moringa seed coagulant was optimal at a concentration of 2–15 gr/L with a decrease in BOD of 95% and COD of 86%. The results of the study show that moringa seeds are effective in reducing the level of organic matter in household liquid waste. With its effectiveness and environmentally friendly nature, moringa seeds can be a sustainable alternative solution for household liquid waste treatment.
