Abstract

The relatively large band gap energy of SnO₂ semiconductors limits their ability to absorb visible light, resulting in suboptimal photocatalytic activity. Although modification of SnO₂ band gap energy through transition metal doping has been widely studied, research that specifically combines nickel doping with the addition of monoethanolamine (MEA) using the sol–gel method remains limited. This study aimed to analyze the effect of nickel doping and MEA addition on the band gap energy of SnO₂ synthesized via the sol–gel method. A quantitative approach with a laboratory experimental design was employed, in which pure SnO₂ and nickel-doped SnO₂ with MEA addition were synthesized as research samples and subsequently characterized using a UV–Diffuse Reflectance Spectrophotometer (UV–DRS). Reflectance data were analyzed using the Kubelka–Munk approach and Tauc plot method to determine band gap energy. The results showed that pure SnO₂ had a band gap energy of 3.59 eV, whereas nickel-doped SnO₂ with MEA addition exhibited a reduced band gap energy of 2.33 eV. These findings indicate that the combination of nickel doping and MEA additive is effective in modifying the optical properties of SnO₂ and extending its light absorption into the visible region, thereby enhancing its potential as a visible-light-driven photocatalytic material. This study contributes to the development of modification strategies for SnO₂-based oxide semiconductors and opens avenues for further research on optimizing dopant and additive compositions as well as directly evaluating the photocatalytic performance of the material.

Abstract

The Jambi Residency held a strategic role in the Indonesian National Revolution (Revolusi Fisik, 1945–1949), particularly in maintaining political authority, organizing military resistance, and controlling vital economic assets, yet narratives about key local actors remain relatively marginalized in national historiography. This study aimed to examine the multidimensional role of Raden Soedarsono in the Physical Revolution in Jambi by analyzing his integrated involvement in civil administration, military affairs, and the management of the petroleum industry. Using the historical research method, which includes heuristics, source criticism, interpretation, and historiography, this study analyzed archives, family documents, museum collections, and oral testimonies to reconstruct Soedarsono’s activities and influence. The findings show that Raden Soedarsono played a central role as Resident of Jambi, Titulair Lieutenant Colonel, and Director of PERMIRI (Perusahaan Minyak Republik Indonesia), with active involvement in political and military decision-making, coordinating the management of oil refineries to support the logistical needs of the Republic of Indonesia, including fuel supplies for AURI (the Indonesian Air Force), and implementing a scorched earth (bumi hangus) policy at the Kenali Asam oil refinery on 29 December 1948 to prevent the reappropriation of strategic assets by the Dutch. This scorched earth policy significantly weakened Dutch economic capacity in Jambi and represented a form of strategic sacrifice for national sovereignty. The study concludes that Soedarsono’s integrative leadership model, which combined civil, military, and economic authority, was crucial for sustaining the revolutionary struggle at the regional level. His leadership legacy offers important lessons on resource sovereignty, ethical leadership, and the significance of local narratives in national historiography, while also underscoring the need to decentralize historical writing beyond Java-centric perspectives and enriching understanding of regional resistance dynamics and technocratic populism in Indonesia’s independence revolution.

Abstract

Silica xerogel is a porous material with a high surface area and active silanol and siloxane groups, making it a promising candidate for use as an adsorbent material. This study aimed to synthesize silica xerogel from palm shell ash as an alternative silica source, characterize its functional groups, and determine its surface area using the methylene blue adsorption method. Silica xerogel was synthesized via a sol–gel method followed by a drying process to obtain the xerogel. Functional group characterization was carried out using Fourier Transform Infrared Spectroscopy (FTIR), while the surface area was determined based on methylene blue adsorption analyzed using UV–Vis absorbance data. The results showed that the synthesized silica xerogel possessed characteristic silica functional groups, namely siloxane (Si–O–Si) and silanol (Si–OH). The methylene blue adsorption process showed a decrease in concentration from 25.7912 mg/L to 2.06 mg/L, with an adsorption efficiency of 92%, an adsorption capacity of 5.9328 mg/g, and a silica xerogel surface area of 21.96032 m²/g. These findings indicate that silica xerogel synthesized from palm shell ash has surface characteristics that support the adsorption of cationic dyes and has potential for use as a biomass waste-based adsorbent material.

Abstract

This study was motivated by the limited number of in silico investigations examining the anti-inflammatory potential of bioactive compounds from Crotalaria medicaginea Lamk, despite the fact that inflammation is a pathological condition largely mediated by the cyclooxygenase-2 (COX-2) enzyme. The study aimed to analyze the potential interactions and binding affinities of bioactive compounds from Crotalaria medicaginea Lamk toward COX-2 as an anti-inflammatory target. A computational research design was employed using an in silico molecular docking approach. The research samples comprised the COX-2 enzyme structure obtained from the Protein Data Bank and bioactive compounds identified from the phytochemical data of Crotalaria medicaginea Lamk. Data were generated through ligand and protein preparation and subsequently analyzed using docking software to determine binding energy values and interaction patterns of amino acid residues at the active site of the enzyme. The results showed that one of the bioactive compounds exhibited stable binding affinity and was able to form interactions at the COX-2 active site, thereby supporting the theory that COX-2 inhibition can attenuate inflammatory responses. The study concludes that the bioactive compounds of Crotalaria medicaginea Lamk have the potential to be developed as anti-inflammatory candidates, with theoretical implications for enriching the literature on the use of medicinal plants based on in silico studies and practical implications as a basis for developing natural anti-inflammatory drugs. This research also opens up opportunities for further in vitro and in vivo studies to confirm the computational findings.

Abstract

Textile dye wastewater contamination, particularly by Rhodamine B, is a serious environmental problem because it is toxic and difficult to degrade naturally. This study aimed to synthesize and evaluate the photocatalytic performance of pure CuO nanoparticles and Ag-doped CuO for the degradation of Rhodamine B. The materials were synthesized using the sol–gel method with an Ag doping concentration of 0.2 mmol. The optical properties were characterized using UV–Diffuse Reflectance Spectroscopy (UV-DRS) in the wavelength range of 185–1100 nm to determine the bandgap energy values using the Kubelka–Munk equation. Photocatalytic activity was tested through the degradation of Rhodamine B under visible light irradiation, with absorbance measurements obtained using a UV–Vis spectrophotometer at a maximum wavelength of 554 nm. The results showed that Ag doping reduced the CuO bandgap from 1.4819 eV to 1.2539 eV. Photocatalytic tests revealed that Ag-doped CuO exhibited higher activity than pure CuO, with Rhodamine B degradation reaching 60.55% at 90 minutes of irradiation, compared with only 32.72% for pure CuO at the same reaction time. This enhanced photocatalytic activity is associated with the role of Ag in suppressing electron–hole recombination, increasing light absorption through the surface plasmon effect, and providing more active sites on the catalyst surface. These findings confirm that Ag-doped CuO has promising potential as an effective photocatalyst for the treatment of textile dye wastewater and the control of environmental pollution.

Abstract

Waste management is one of the most pressing environmental issues in developing cities, including Bukittinggi City, and therefore requires governance that is effective, sustainable, and compliant with regulatory frameworks. The Dinas Lingkungan Hidup (DLH) of Bukittinggi, as the competent authority, plays a strategic role in directing and coordinating various solid waste programs. This study aims to analyze the role of DLH Bukittinggi in waste management, encompassing its functions in planning, implementation, supervision, environmental education, and cooperation with communities and third parties. The research employed a descriptive qualitative approach through literature review, document analysis, and policy analysis related to local waste governance. The results indicate that DLH Bukittinggi has implemented several waste management programs, including the development of waste banks (bank sampah), the provision of waste management facilities and infrastructure, waste reduction at the source, and transportation and final processing at the Tempat Pemrosesan Akhir (TPA) facility. Nevertheless, the implementation of these programs still faces multiple challenges, such as limited waste collection fleets, low community participation in waste sorting, and the need to strengthen education and supervision. The study concludes that optimizing the role of DLH Bukittinggi requires strengthening institutional capacity, fostering multisectoral collaboration, and enhancing public awareness so that the waste management system can operate more efficiently and sustainably. These findings are expected to serve as a basis for evaluation and recommendations to improve waste management policies in Bukittinggi City.

Abstract

Students often struggle to generate ideas, articulate their thoughts, and cope with speaking anxiety, resulting in suboptimal development of their writing and speaking skills. The integration of digital media such as podcasts with structured instructional models is considered a promising approach to address these barriers. This study aimed to evaluate the effectiveness of an AI-assisted ROAr method in improving the targeted skills among senior high school students. A quantitative approach was employed using a one-group pre–post design (without a control group) with a sample of 43 students. The instructional method combined digital authentic materials and observational practice, while data were collected through pre- and post-intervention scores and analyzed using a paired-samples t-test. The results showed significant and consistent improvements in post-intervention scores, indicating that the AI-assisted ROAr method was statistically effective in enhancing students’ performance on the measured variables, likely through reducing speaking anxiety, strengthening ideation, and increasing exposure to authentic input. These findings are consistent with the literature highlighting the benefits of podcasts and learning approaches that connect instructional content with real-life experiences. Future research is recommended to employ experimental designs with control groups, larger sample sizes, measurements of affective variables (anxiety, motivation), and mixed-methods approaches to explore the mechanisms of change more comprehensively. In practical terms, educators are encouraged to systematically integrate digital media and observational strategies, with appropriate adjustments to frequency and supporting activities, to optimize learning outcomes.

Abstract

The development of practical instructional media in building engineering education is essential for supporting students’ understanding of reinforced concrete structural concepts in accordance with applicable construction standards. However, studies that specifically develop learning media in the form of physical replicas of sloof and column reinforcement based on the Indonesian National Standard (SNI) 2847:2019 remain limited. This study aimed to develop and test the feasibility of instructional media in the form of sloof and column reinforcement replicas based on SNI 2847:2019 for use in the Praktek Dasar Batu dan Beton (Basic Masonry and Concrete Practice) course. The research employed a research and development (R&D) approach using the ADDIE development model. The study participants comprised four validators—two subject-matter experts and two media experts—and twenty-three students of the Building Engineering Education Study Program as media users. Data were collected using validation and practicality questionnaires and were analyzed using Aiken’s V index and percentage analysis. The results showed that the replica media achieved a high level of validity, with average Aiken’s V values of 0.86 from material experts and 0.94 from media experts, as well as a practicality level of 90%, which falls into the “highly practical” category. These findings indicate that the replica media are feasible and effective as practical instructional media to help students understand sloof and column reinforcement details in a concrete and standard-compliant manner, and they offer practical contributions to the development of experience-based learning media in building engineering education.

Abstract

Exposure to chromium(III) ions in liquid waste can have adverse impacts on human health and the environment, thereby necessitating treatment methods that are effective, economical, and environmentally friendly. Various natural materials have been investigated as heavy metal adsorbents; however, studies that specifically evaluate tanah napa from Pesisir Selatan Regency as an adsorbent for Cr³⁺ in a column (continuous) system remain limited. This study aimed to determine the material characteristics and the optimum conditions for Cr³⁺ ion adsorption using activated tanah napa. The research employed an adsorption method in a continuous system, in which the adsorbent with a particle size of 200 mesh (70 µm) was prepared through calcination at 750°C and activation using 1 M KOH. Material characterization was carried out using X-ray Fluorescence (XRF) and Fourier Transform Infrared (FTIR) spectroscopy, while Cr³⁺ ion concentrations were analyzed using an Atomic Absorption Spectrophotometer (AAS). The results showed that the activation process increased the SiO₂ content to 65.781% and enhanced the presence of silanol and siloxane groups that play a role in the adsorption mechanism. The optimum conditions for Cr³⁺ adsorption were achieved at pH 4 with a capacity of 1.0686 mg/g, an initial concentration of 200 mg/L with a capacity of 0.3343 mg/g, and a flow rate of 20 drops/min with a capacity of 1.8464 mg/g. The decrease in adsorption capacity at higher pH values was associated with the formation of chromium hydroxide precipitates, whereas the increase in flow rate reduced the contact time between adsorbate and active sites on the adsorbent. These findings indicate that activated tanah napa has promising potential to be developed as a low-cost alternative adsorbent for heavy metal waste treatment in continuous systems.

Abstract

Although soft soil stabilization has been widely studied, research that specifically examines the use of ceramic waste as a subgrade soil stabilization material on the Proyek Pembangunan Jalan Tol Trans Sumatera Ruas Betung (Simpang Sekayu)–Tempino–Jambi Seksi 2B remains limited. This study aimed to analyze the effect of adding ceramic waste on improving the bearing capacity of soft soil based on California Bearing Ratio (CBR) values. A quantitative approach with a laboratory experimental design was employed, using soft soil samples taken at STA 110+600 in Musi Banyuasin Regency through purposive sampling. Ceramic waste was used as a stabilization material with dosage variations of 5%, 10%, 15%, and 20% of the soil weight. Data were collected through tests of physical soil properties, standard Proctor compaction, and CBR tests under unsoaked and soaked conditions, then analyzed quantitatively and supported by a One Sample t-test using SPSS software. The results showed that the addition of ceramic waste significantly increased the soil CBR values, with the highest value obtained for the 20% ceramic waste mixture. In addition, ceramic waste was found to reduce soil plasticity and increase the density achieved by compaction. These findings indicate that ceramic waste has the potential to be utilized as a relatively low-cost stabilization material for clayey soils to support more sustainable road construction and provide an empirical basis for the use of construction waste in improving subgrade performance in pavement structures.
