Abstract

The use of soilless planting media is currently increasingly in demand because land for agriculture is decreasing as a result of it being used for residential and industrial construction. One of the preferred planting media options is fiber, both natural and synthetic. This research aims to analyze publication trends regarding the use of fiber as a soilless planting medium, using bibliometric methods and mapping with the VOSviewer application. Publication data was taken from Google Scholar between 2019 and 2024, and a total of 942 documents were found during that period. Publication trends regarding the use of fiber as a soil-free planting medium fluctuate, increasing and decreasing every year. The number of documents in 2019 decreased, although not too significantly. But from 2019 to 2023 there was a soaring increase. At the beginning of 2024, interest in research on the use of fiber as a soil-free growing medium will increase rapidly, as shown by the publication of 52 publications at the beginning of the year. The results of three types of mapping show that research on fiber continues to develop along with the various types of fiber used as planting media. Therefore, further research regarding the development of fiber as a soilless growing medium is still relevant and very necessary and could be a driving force for further research to find innovations in this field.

Abstract

The establishment of metabolic equilibrium in the soil ecosystem the following insolation is a prerogative of soil communities. These communities comprise microorganisms of diverse species and populations. The hydrocarbon-degrading communities (i.e., hydocarbonclastics) are found in petroleum or crude oil, polluting soil ecosystems. Others, the non-petroleum degrading microbial communities are diverse in nature and occur in soil, water, and air ecosystems. In the event of oil pollution with inherent disequilibrium in the ecosystem, the prejudicial nature of the petroleum will reduce the biomass of the non-hydrocarbon degrading organisms. Consequently, there will be an insurgence of the hydrocarbon degraders to metabolize the xenobiotics and bring the affected ecosystem to a balance and equilibrium. This is the hallmark of the entire ecosystem function. For other non-petroleum degraders in an ecosystem insolted with xenobiotics except petroleum, they will consolidate in their degradative activity to bring the affected ecosystem to a balance and equilibrium.  Overall, the insolation of an ecosystem with any xenobiotics results in a disequilibrium, in which the indigenous microbial communities through their metabolic activities will bring the affected ecosystem to a balance and equilibrium.

Abstract

In the world of the chemical industry which continues to develop, factory design is the first step that determines the success of a project. However, to ensure that sustainability, efficiency and a positive impact on the economy can be achieved, economic evaluation is a critical aspect that must be considered carefully. Economic evaluation has a central role in the design stage of industrial chemical plants. However, until now, there is still no research that explains step by step how to calculate economic evaluations, especially in the field of industrial chemistry. Based on this, the aim of this article is to demonstrate how to calculate economic evaluations in chemical plant design. To provide a detailed understanding, we present a step-by-step example of calculating an economic evaluation of the design of a gold mining using amalgamation method. It is hoped that this article can have a significant impact by illustrating effective ways to optimize financial sustainability, make wise data-based decisions, and manage risk carefully in the design of industrial chemical plants through in-depth analysis using economic evaluation. Here, this article not only serves as an important basis for corporate decision-making, but also provides valuable guidance for the chemical industry in designing efficient and economically sustainable production facilities.

Abstract

The study evaluates the potential of rice husk (RH) and sawdust (SD) as energy sources by analyzing their physicochemical properties and combustion efficiencies. These common waste materials from Gwagwalada, Abuja, Nigeria, were processed into briquettes at varying ratios. Proximate analysis showed moisture content of 7.5–9.2% and ash content of 2.1–3.5%. Calorific values ranged from 18,509.84 kJ/kg (100% SD) to 22,658.77 kJ/kg (100% RH). The burning rate (BR) correlated with calorific value, with the 50:50 SD/RH mixture having the highest BR (0.003 g/min), indicating rapid combustion, while 100% SD had the lowest BR (0.0015 g/min), supporting slower combustion. All briquettes exhibited smokeless behavior, reducing greenhouse gas emissions and offering a clean energy alternative. This study highlights the potential of agricultural waste for energy security, environmental management, and rural economic development in Nigeria.

Abstract

Azo compounds possess the R-N=N-R’ functional group are used as dyes and from the literature survey, their biological activities are enhanced when coupled with other transition metal complexes of Co(II), Cu(II), Mn(II), Ni(II) and Zn(II) with a novel bis azo dye 2, 2 1 [benzene-1, 3-diyl di(E) diazene 2,1-diyl] bis (4-chloroaniline) derived from mphenylenediamine and p-chloroaniline were synthesized. Data were supported by characterizations using UV-Vis spectroscopy and these compounds have been done based on elemental analysis, electronic data, Fourier Transform Infra-Red (FT-IR), 1H Nuclear Magnetic Resonance (NMR), powder X-ray diffraction and thermal analysis, and magnetic data. From the analytical and thermal data, the stoichiometry of the complexes is 1:1 (metal: ligand). Based on physicochemical data octahedral, tetrahedral, and square planar geometries were assigned for the complexes. The ligand and metal complexes were screened for their antimicrobial activity. The azo of 2-aminopyridine with its cobalt (II) complex exhibited antimicrobial activity at higher and lower concentrations.

Abstract

In the framework of international efforts to achieve carbon neutrality, this research investigates the potential of petroleum reserve residue as a sustainable energy source, focusing on unconventional crude oils. The discovery of alternative resources, such as bitumen, heavy crudes, and high-acid crudes—which combined make up almost two-thirds of the world's oil reserves—has become necessary due to the depletion of traditional oil stocks. This study looks at the difficulties in processing these non-conventional oils, especially their high acidity, which poses environmental risks and severely corrodes refinery equipment. The article discusses a revolutionary method for upgrading and treating these unconventional crudes without the need for external catalysts or molecular hydrogen, utilizing supercritical fluids (supercritical methanol and water). The evaluation emphasizes how well this process works to produce synthetic crude oil that is appropriate for use in refineries that are currently in operation by lowering asphaltenes, contaminants, and total acid numbers (TAN). There are suggestions for more study into low-temperature, low-pressure catalytic alternatives, although the economic feasibility of high-temperature, high-pressure processes is questioned. One important step in striking a balance between technical growth and environmental preservation is the emphasis on the potential of this methodology in promoting sustainable energy production and lowering environmental pollution.

Abstract

The synthesis of zeolite from fly ash has been investigated. The method used for the synthesis of zeolite in this research is the smelting method followed by a hydrothermal process. The zeolite synthesis was characterized using XRD and SEM. Based on the research results, it was found that fly ash can be synthesized into Na-P zeolite with morphology like coral, and cancrinite zeolite and sodalite with morphology like seaweed. The optimum condition for zeolite synthesis occurred at a hydrothermal process at 160°C for 24 hours with the formation of cancrinite zeolite. The synthesized zeolite resulting from the separation of 4 M of HCl formed Na-P zeolite and silica phase crystals which had the most optimum absorption of ammonium with an adsorption capacity of 18.025 mg/g with the adsorption kinetics model in the form of pseudo-second-order with a constant rate of 0.557 h-1 .

Abstract

Indonesia is committed to achieving net zero emissions by 2060 through short-term policies. The focus includes energy efficiency, renewable resources in the electricity sector, and transportation electrification. Transportation electrification leads to increased use of lithium-ion batteries, predicted to grow at a CAGR of 25.45%. The installed capacity of lithium-ion batteries is expected to reach 10.5 TWh, with 8.1 TWh in electric vehicles by 2030. The waste from lithium-ion batteries in Indonesia is estimated to be 250,000 tons by 2020, increasing with electric vehicle policies. By 2040, it is projected to require 0.2 million tons of cobalt and 1.3 million tons of nickel. Recycling support to address domestic lithium unavailability results in a circular economy worth US$ 49,767,416 and reduces emissions by 7,472 tons of CO2 from devices sold in 2022.

Abstract

The objectives of the study were to characterize natural zeolites from Cikalong, Tasikmalaya, Indonesia, and test for ammonium removal. Characterization was performed by using X-ray fluorescence (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope (SEM). According to XRF analysis, the ratio of Si/Al was 6.8. The XRD pattern revealed that the zeolites were mordenite dominant phase. The SEM images showed the needles shape of mordenite typical morphology. Ammonium removal test was performed in the batch reactor with a variation on natural zeolite mass loading and adsorption time. Various isotherm models, i.e., Langmuir, Langmuir-Vageler, Freundlich, and Tempkin were fitted with the kinetic data by using optimization of the sum of the least square method. The Langmuir-Vageler model was best fitted with the error sum of squares 0.01. Furthermore, the study on kinetic models such as Lagergren’s 1st order, Pseudo 2nd order, Elovich, and Intraparticle diffusion was fitted with the ammonium adsorption isotherm data by using optimization of the sum of the least square method. The Pseudo 2nd order showed the smallest error sum of squares 0.007.
