Abstract

Purpose: Potentiality of six reclaimed mine sites for crop production at Goldfields Ghana Limited, Tarkwa Mine was holistically assessed. Research methodology: Soil pH was traced using HI 9017 microprocessor meter while total nitrogen (TN), organic matter (OM) and organic carbon (OC) were determined by Kjeldahl digestion, distillation and Walkley-Black Methods. Calcium (Ca), magnesium (Mg), potassium(K), sodium (Na), were further determined in 1.0 M ammonium acetate (NH4OAc) extract, using hydrogen and aluminum in 1.0 M KCl, by EDTA titration and flame photometry.  Results: Optimum soil pH, compared with other parameters down the trend was less than 4.33. In cmolkg-1, OM at Ajopa natural forest soil (2.52) was greater than West Heap (2.08). TN differed significantly (p ? 0.001) such that, Ajopa natural forest (0.13%) was greater than West Heap (0.11%). West Heap Ca (3.52) was greater than Bridge Dump Ground (BDG’s) (1.78) while Mg (1.25) at BDG was greater than West Heap (1.22). West Heap’s K (0.16) was greater than BDG’s (0.13). Sodium was entirely low (< 5 %). But acidity of Ajopa natural forest (1.90) was greater than BDG’s (1.89) while effective cation exchange capacity (ECEC) of West Heap (5.95) was greater than BDG’s (4.68). Conclusions: The study assessed reclaimed mine soils in Tarkwa, Ghana. Findings show highly acidic pH and low nutrients, limiting crop productivity. Soil improvement with lime, organic matter, and suitable crops is required for sustainable livelihoods. Limitation: Study sites sparsely located and require more experience to locate sampling points. Contribution: Analyses clearly revealed poor agglomeration of cation exchange capacities due to inadequate fertility of the seven-year old reclaimed mine sites. Hence, it may not give good crop yields for sustainable economic livelihoods strategies without long-term augmented fertilization and liming.

Abstract

Purpose: High-voltage electrical equipment requires grounding installation to protect lives in freshwater swamps with a hydrogen potential of 6.75. To build a grounding structure, it is necessary to know the resistance value and grounding materials, namely, copper-coated rod electrodes at different depths. Research methodology: The research was conducted in a freshwater swamp close to the shampooing substation using field observations and direct measurements of soil resistance values, followed by a literature review and comparisons using COMSOL simulation and FEM Analysis. Results: The results of direct research and simulations indicate that to accomplish a grounding resistance value < 5 ? according to the PUIL 2011 standard for a single-rod system made of copper, it is necessary to optimize the depth of the grounding electrode within a range of 10 m, which differs from the simulation results of ground resistance measurement and the Comsol application. The percentage error was 1.05%. Conclusion: The findings demonstrate that increasing electrode depth effectively reduces grounding resistance in freshwater swamp environments, though variations exist between field and simulated data. Limitations: This study analyzed the results of measurements and grounding analysis using COMSOL Multiphysics at a depth of 1 m for a particular type of copper-coated round rod electrode at depths of 1, 1.5, and 2 m. Contributions: The results of this study offer information on the usefulness of grounding resistance in freshwater wetlands with a pH greater than 6, where several rod electrode types can be utilized for comparison in future research.

Abstract

Purpose: This study investigated the effects of process variables on the proximate, functional, and sensory properties of plantain flour. Research Methodology: The plantain fruit was sorted and hand-peeled using kitchen knives. It was then cut into various slices of 2 – 6 mm and steeped in citric acid solutions with concentrations ranging between 1 – 5 %. The steeping time varied between 30 – 120 min. The pretreated plantain slices were processed into flours. Process parameters were analyzed using the response surface methodology of Design Expert software. Results: The proximate composition showed no significant differences (p > 0.05), but functional and sensory properties varied significantly (p < 0.05). Flour samples exhibited desirable bulk density, high water absorption capacity, and favorable swelling power, indicating potential for bakery and complementary foods. Sensory analysis revealed that citric acid pretreatment improved moldability, texture, and overall acceptability, with the best results at citric acid concentration of 2.79%, slice thickness of 5.63 mm, and steeping time of 50.41 minutes. Conclusions: Citric acid treatment significantly enhanced functional and sensory properties of plantain flour, making it suitable for diverse food applications Limitations: This study did not consider the application of other optimization methods, such as genetic algorithms and particle swarm optimization, to estimate the optimum points. Future studies could focus on these areas Contribution: The validation of the optimization processes showed success in the application of citric acid in the production of novel plantain flour.

Abstract

Purpose: This model aims to solve a Green Heterogeneous and Stochastic Capacitated Vehicle Routing Problem that considers risks and environmental hazards. Research Methodology: Regarding an NP-hard and complex problem, and after confirming the accuracy of the problem-solving in smaller dimensions by GAMS software, the problem is solved by the metaheuristic algorithm of multi-objective particle swarm optimization (MOPSO) and its coding in MATLAB software. Results: The results urge that using random sampling and probability The findings indicate that MOPSO effectively produces optimal or near-optimal solutions with significantly reduced computational time compared to GAMS. In small-scale cases, results matched the exact solutions, while larger-scale instances demonstrated the efficiency of the algorithm in handling complex routing problems. Sensitivity analyses revealed that prioritization of objectives—such as environmental impact, reliability, or routing cost—led to different but balanced routing strategies, confirming the model’s adaptability. Conclusions: The proposed model ensures reliable and environmentally conscious waste transportation by integrating cost, risk, and time-window considerations. It demonstrates strong performance in optimizing multi-objective routing problems under uncertainty. Limitation: The proposed method is a routing problem and has been applied for the Green Heterogeneous and Stochastic Capacitated Vehicle Routing Problem. Future researchers may work on real data sets and hazardous biomedical waste data. Contribution: Based on the results presented, the model derived in this study can support decisions such as routing, prioritization, and time to reach each node, so that the costs of routing, system reliability, environmental issues, and penalties for violation of the priority and maximum time elapsed for vehicles are considered.

Abstract

Purpose: This study aimed to explore the effectiveness of ultraviolet (UV) radiation in the conservation of palm wine by reducing its microbial load, specifically mold, yeast, and bacteria. Research Methodology: Palm wine was conserved by sterilization with ultraviolet rays. The time of contact of the rays and the intensity of the rays with palm wine were varied. The microorganisms considered include molds, yeasts, and bacteria. Results: The results showed that the microbial load of sterilized palm wine decreased with time of contact with the rays. The microbial load of the wine before and after sterilization was determined. Moreover, the microbial load further decreased during the storage of the sterilized samples. In fact, sterilization time of 240 seconds (4 minutes) reduced the mould and yeast from  to  and then to zero after 10 days of preservation. Conclusions: UV radiation is an effective method for reducing microbial contamination in palm wine, with an optimal sterilization time of 240 s providing the best results. This sterilization process not only reduced microbial presence immediately but also extended the shelf life of palm wine during storage. Limitations: This study did not examine the impact of stirring palm wine during sterilization on microbial load reduction, which could potentially influence the treatment’s effectiveness. Contribution: This study established an ideal sterilization time of 240 s (4 min) for palm wine, providing an effective method for its preservation and ensuring its safety for consumption.

Abstract

Purpose: The Indonesian government has set a new renewable energy target of 23% by 2024, which will play an important role in the energy transition program, particularly in rural areas. This study describes the village government's perception of energy transition through the energy-independent village program in Mojokerto Regency. Research methodology: This article examines village government perceptions of energy transition using descriptive qualitative research, and the theory of social capital is an analytical tool for viewing village perceptions in Mojokerto Regency in realizing an energy-independent village. Results: Findings revealed that most village governments in Mojokerto Regency do not prioritize energy transition, perceiving it as secondary to poverty reduction, infrastructure improvement, and economic empowerment. Although some villages have initiated renewable energy projects, such as biogas in Pacet and micro-hydropower plants in Seloliman, Jembul, and Kebontunggul, these initiatives remain limited and fragmented. Village governments still view energy transition as resource-intensive, requiring substantial funding, technology, and external support. Conclusions: This study concludes that traditional development perspectives emphasizing physical infrastructure and economic growth dominate village agendas, thereby sidelining renewable energy programs. Without alignment between central, regional, and village policies, the realization of energy-independent villages will remain slow and ineffective. Contribution:  This research will be input to the government of Mojokerto Regency on the issue of energy transition, as well as for the central government through the Ministry of Villages in assessing the village's ability to face the energy transition process. Limitations: Because only a few villages are discussed in this study, this limitation will be balanced with an overview of other villages.

Abstract

Purpose: This study aims to determine the effects of transfer pricing, thin capitalization, deferred tax, and inventory intensity on tax avoidance. Method: This study uses a quantitative approach with a sample of all companies listed on the Indonesia Stock Exchange (BEI) from 2018 to 2022. A purposive sampling technique was used for sample selection, and a sample of 107 companies was selected. This study uses a panel data analysis. The results of the analysis show that thin capitalization and deferred taxes have a negative effect on tax avoidance, while transfer pricing and inventory intensity have no effect on tax avoidance. Results: The findings reveal that transfer pricing and inventory intensity have no significant effects on tax avoidance. Thin capitalization shows a negative and significant effect, suggesting that higher debt usage reduces tax avoidance due to creditor scrutiny and compliance pressure. Deferred tax also negatively affects tax avoidance, indicating that higher deferred tax expenses reflect greater compliance and lower avoidance. The model’s adjusted R² was 7%, implying that most variations in tax avoidance are explained by other unobserved factors. Conclusions: Deferred tax and thin capitalization serve as deterrents to tax avoidance, whereas transfer pricing and inventory intensity are not significant drivers. Limitations: This study relies on publicly available financial reports, limiting the measurement accuracy of hidden tax-avoidance practices. It also covers a period influenced by Covid-19 tax incentives and voluntary disclosure programs, which potentially affect behavior. Contribution: This study extends the literature by integrating inventory intensity into tax avoidance models and providing evidence from Indonesian firms, offering insights for policymakers and regulators to strengthen anti-avoidance measures.

Abstract

Purpose: This study aimed to analyze the knowledge, attitudes, and compliance with antiretroviral (ARV) antidotes among HIV patients at the Central Bangka Regional General Hospital. Research Methodology: This study used a qualitative method with a phenomenological approach. The technique for selecting respondents was a non-probability sampling technique, purposive sampling. Nine informants participated in 9 people. Data were collected using an in-depth interview guide. Results: Findings from the research show that several informants had insufficient knowledge about compliance in taking ARV antidotes. Even though the informants' attitude towards compliance with antiretroviral (ARV) antiretrovirals was relatively good, several key informants stated that they had stopped taking antiretroviral (ARV) antidotes for several months because they felt healthy. However, several months later, they experienced adverse effects that resulted in declining health. Conclusions: The study concludes that Inadequate knowledge and misconceptions about ARV therapy remain significant obstacles to sustained adherence. Strengthening education, family involvement, and consistent supervision are essential for enhancing compliance and improving health outcomes for people living with HIV. Limitations: The study was limited to a small number of participants from a single hospital, which restricts broader generalization. Contribution: This research provides practical insights for healthcare providers and policymakers to design targeted interventions, improve supervision, and foster cross-program collaboration to ensure consistent ARV adherence among patients with HIV, ultimately supporting public health goals in HIV management.
