Abstract

Moa Island is one of the remote Indonesian Islands that face the difficulty in accessing clean water, especially during the dry season. One way to get clean water is by drilling for groundwater. The drilled groundwater in Kaiwatu Village on Moa Island, Southwest Maluku Regency, Maluku Province, was analyzed for its content to obtain primary data. Primary data related to the quality of drilled groundwater sources includes chemical, physical, and microbiological parameters. The results of chemical parameters obtained from the test results were <0.01 mg/L fluoride, total chromium, nitrite, nitrate, iron, manganese, zinc, cyanide, lead, <0,001 mg/L cadmium, 17.9 mg/L hardness, sulfate 147.55 mg/L, pH 7.50, and organic substances 2.8 mg/L.  The physical parameter analysis showed a turbidity level of 3.71 NTU, a temperature of 26.8 °C, and a color of 5 TCU. The microbiological parameters obtained by the analysis were 0/100 mL. Primary data was then compared with secondary data, namely environmental health quality standards and air health requirements from Minister of Health Regulation No. 32 of 2017 for chemical and physical parameters, as well as water quality requirements and monitoring from Minister of Health Regulation 416/MENKES/IX/1990 for microbiological parameters. The analysis results using a comparison of primary and secondary data showed that all parameters contained in the primary data had values below the safe limits set by the requirements in the secondary data.

Abstract

Fly Ash and Bottom Ash (FABA) is the waste from burning coal in coal-fired power plants and consists of chemical compounds, such as SiO₂, Al₂O₃, Fe₂O₃, and CaO. This waste poses an environmental challenge and an opportunity for the construction industry. This study conducted a comparative analysis of the composition of FABA from several coal-fired power plants in Indonesia and other countries, such as Thailand, China, Malaysia, France, Italy, and Portugal. In particular, this study assessed the XRF data from several other references. The XRF test data showed significant variations in the FABA content, influenced by coal type, combustion method, and emission management technology. The high SiO₂ content in the Cirebon and Teluk Sirih coal-fired power plants showed potential for pozzolanic applications. Meanwhile, the high Fe₂O₃ in Tanjung Enim and Sudimoro had the potential for metallurgical applications. In addition, the high CaO content of Teluk Sirih allowed its use in lime production and soil stabilization. However, high levels of SO₃, especially in Cirebon, required more attention in processing because of its impact on concrete quality and environmental pollution. With proper processing, FABA could be a valuable resource in various industries, reducing reliance on natural raw materials. This study highlighted the potential for the sustainable use of FABA and proposed management measures to address environmental challenges. The optimal use of FABA reduced negative environmental impacts and opened up significant economic opportunities, supporting the circular economy in the energy and construction sectors.

Abstract

In the post-pandemic era, many interactive activities have been flexibly generated through virtual conditions. Accordingly, some problems could appear in terms of leadership, such as difficulties in maintaining the audience’s attention during the event. Thus, the utilization of a command-based leadership style that could straightforwardly maintain audience focus ought to be considered to be adopted. However, both the command-based leadership style and its prospective aspects have not been widely understood by society. This community service aims to deliver a proper understanding of the command-based leadership style through interactive virtual discussion between experts in teaching activities of defense-based science and society consisting of Indonesian teachers, high school students as well as academics. Statistical results of pre-test and post-test scores showed enhancement of the participants’ understanding of command-based leadership. Hopefully, some relevant aspects of their new perspective of command-based leadership can be properly adopted and effectively implemented to answer current challenges, such as in terms of managing people in virtual conditions.

Abstract

This study investigates the synthesis and characterization of radar absorbing material (RAM) of spinel ferrite based (Ni₁₋ₓMnₓFe₂O) has been performed by hydrothermal method using Mn(NO₃)₂·4H₂O, Fe(NO₃)₃·9H₂O, Ni(NO₃)₂·6H₂O, and CTAB as a precursor. The effect of Mn doping on the structural, optical, and magnetic properties was examined by varying the Mn concentration (x=0-1). X-Ray Diffraction (XRD) analysis confirmed a single-phase cubic spinel structure for all samples, with a shift in diffraction peak observed as the Mn concentration increased, attributable to the difference in ionic radii between Ni2+ and Mn2+. The band gap value decreased with increasing Mn doping, which enhanced electron hopping within the lattice and consequently contributed to the observed dielectric loss. Magnetization tests indicated an increase in magnetization at low doping levels (3 wt%), which strengthened the magnetic loss mechanism, while excessive doping led to a reduction in ferrimagnetic properties, approaching paramagnetic behavior. FESEM revealed agglomerated nanoparticles with sizes ranging form 11–27 nm, this nanoscale dimension is advantageous as it increase the specific surface area for enhanced  interaction with electromagnetic waves. Conclusion, Mn doping successfully enhanced the performance of NiFe₂O₄ system as a candidate for new radar-absorbing materials, with the optimum composition achieved at low doping levels. In practical terms, this material can be applied as a lightweight coating in stealth aircraft technology or as electromagnetic interference (EMI) shielding in modern telecommunications devices.

Abstract

This study reports the synthesis and characterization of SnO and SnO₂ catalysts for biodiesel production from crude palm oil (CPO) via interesterification. SnO was synthesized using the hydrothermal method, while SnO₂ was prepared through the sol–gel route. The catalysts were applied in the interesterification of refined bleached palm oil with methyl acetate at an oil : methyl acetate molar ratio of 1:9, catalyst loading of 0.25 wt%, reaction temperature of 65 °C, and reaction time of 3 h. X-ray diffraction (XRD) analysis confirmed the formation of tetragonal SnO and rutile tetragonal SnO₂ phases. Biodiesel quality was evaluated according to SNI 7182:2015 parameters. Biodiesel produced using SnO showed density of 861 kg/m³, viscosity of 3.09 cSt, water content of 0.25%, free fatty acid (FFA) of 0.66%, and iodine value of 44.04. Meanwhile, SnO₂-catalyzed biodiesel exhibited density of 886 kg/m³, viscosity of 3.12 cSt, water content of 0.22%, FFA of 0.56%, and iodine value of 36.03. GC–MS analysis identified methyl oleate as the dominant compound in SnO-catalyzed biodiesel, while methyl palmitate was dominant in SnO₂-catalyzed biodiesel. These results indicate that both catalysts have potential as alternative heterogeneous catalysts for biodiesel production from palm oil via interesterification.

Abstract

Fly ash, a byproduct of coal combustion, has attracted increasing attention as a low-cost adsorbent for environmental remediation. This study aims to investigate the effect of alkali activation on the structural and surface characteristics of fly ash and to evaluate its potential for oil remediation. In this work, fly ash was activated using sodium hydroxide (NaOH) followed by thermal treatment at 250 C. The structural and surface properties of the materials before and after activation were characterized using Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), and Brunauer–Emmett–Teller (BET) surface area analysis. FTIR analysis indicated changes in the surface functional groups of fly ash after alkali activation, while hydrocarbon-related bands observed after contact with used oil suggested the presence of oil-derived compounds on the adsorbent surface. XRD results showed that the activated fly ash retained a predominantly amorphous phase with slight changes in crystallinity. BET analysis revealed only a slight increase in specific surface area from 22.71 to 23.53 m2g-1, accompanied by a small increase in average pore diameter from 5.49 to 5.77 nm, indicating limited modification of the mesoporous structure after alkali activation. These structural modifications suggest that alkali activation alters the surface characteristics of fly ash and may support its potential use in oil remediation. The findings indicate that alkali-activated fly ash has potential as an economical and sustainable adsorbent for environmental remediation applications, particularly for the treatment of oil-contaminated waste.Keywords: alkaline activation, adsorbent, BET, FTIR, XRD
