Abstract

Geostatistic is a statistical tool used in the mining sector to estimate and classify mining resources at a specific location. The purpose of this study was to evaluate the distribution or model of nickel resources, as well as estimate and classify nickel resources using a geostatistical approach. This study used data from exploration drilling at one of the nickel mining concessions in Sulawesi, Indonesia. The data set included 464 drill holes with an average distance of 50–100 m. The initial stage in this study was to develop a geological model, followed by descriptive statistical analysis, with the results of the variance coefficient ranging from 0.5 to 1.5 and normal distribution, indicating that the ordinary kriging method can be used and is considered adequate to produce sound and consistent findings. The values obtained from the variogram analysis on the spherical model will be used as parameters in the ordinary and efficiency kriging processes. Based on the estimation and classification of nickel resources using ordinary and efficiency kriging, the total measured, indicated, and inferred nickel resources are 39, 1.25, and 3 million tons, respectively, with an average Ni content of 1.16%.

Abstract

The negative effects of increased radiation dose can impact healthy tissue surrounding the target area, necessitating careful management to minimize side effects and meticulous planning in radiation therapy. This study aims to determine the peripheral dose of a 6 MV photon beam and compare the measured values with the estimates from the Treatment Planning System (TPS). Dose calculations were performed using the Analytical Anisotropic Algorithm (AAA) in the ECLIPSETM TPS on a virtual water phantom with a 6 MV photon beam, delivered by a Clinac CX linear accelerator (LINAC) at Unand Hospital. Photons were used with variations in target depth of 1.5, 5, and 10 cm, as well as variations in measuring distances of 3, 5, 7, 10, and 15 cm outside the irradiation field. The area of irradiation used varied of 5×5 and 10×10 cm2. The measurement results based on the distance of the field edge showed that the dose percentage decreased below 10% when passing a distance of 5 cm for a field area of 5×5 cm2, and for a field area of 10×10 cm2, the dose percentage decreased below 10% after passing a distance of 7 cm from the edge of the irradiation field. The peripheral dose intensity in the area outside the target will decrease along with the increasing measurement distance from the edge of the field and the depth due to the interaction of radiation with the medium, which causes the spread and absorption of photons in the medium.

Abstract

Our study investigates the remarkable capacitance performance of a supercapacitor cell featuring electrodes synthesized through the liquid-phase exfoliation (LPE) method using environmentally friendly linear alkylbenzene sulfonate (LAS) surfactant. We explored different synthesis temperatures (15, 30, and 90 °C) to evaluate their impact on reducing sonication time. The electrodes, created by drop-casting graphene onto a silver plate substrate and heated at 50 °C, demonstrated exceptional cyclic voltammetry (CV) and charging-discharging (CD) results. Notably, the graphene synthesized at 90 °C exhibited a maximum capacitance of 59 F/g at a 13 mV/s scan rate in a 1.3 M KOH electrolyte gel, leading to superior energy density as shown in the Ragone plot. Our findings highlight the crucial role of increased synthesis temperature in LPE, enhancing supercapacitor cells through the expansion of sp2-ordered grain size, evident in the Raman shift data's ID/IG increase.

Abstract

Star pomfret (Trachinotus blochii) is one of the most sought-after types of marine fish in Indonesia. The production of feed for star pomfret fish is an important factor because it is related to their survival and ability to grow well.  Therefore, formulating the feed formulation for star pomfret (Trachinotus blochii) is very important to minimize feed production costs and ensure the nutritional adequacy of the fish. Therefore, we change the feed for star pomfret fish as a linear programming (LP) problem and solve it using the Hybrid Differential Evolution-Wolfe Algorithm (HWDEA).  HWDEA combines the Wolfe method, which efficiently transforms constraints into a system of linear equations, with the use of the Differential Evolution Algorithm (DEA) to find a global optimization solution, which is a solution that is not trapped in a local minimum.  We improve accuracy and efficiency by using HWDEA to find the optimal solution for this fish feed production. Our HWDEA can also overcome the limitations of traditional methods such as the simplex algorithm.  Thus, we can show that HWDEA successfully reduced feed production costs from 12,353 IDR to 9,035 IDR per kg while maintaining nutritional balance.  We can conclude that the HWDEA method successfully adapted to price fluctuations and raw material availability, allowing it to produce an optimal raw material composition in feed production.  Therefore, HWDEA can be used as an efficient tool to provide significant cost savings for supporting sustainable and profitable fish farming.

Abstract

This study contributes to understand the medicinal properties of Silybum marianum L., commonly known as milk thistle. The result demonstrates the plant's antioxidant and antibacterial activities have the potential to significantly impact the fields of botany, pharmacology, and medicine. The study was initiated by culturing different parts (root, stem, cotyledonary leaves, and leaves) on a Murashige and Skoog (MS) medium supplemented with benzyl adenine (BA) and naphthalene acetic acid (NAA) for callus induction. One of the key findings of this study is the effectiveness of the 0.5 mg L-1 BA and 2.0 mg L-1 NAA combination for callus initiation. As revealed by the results, this combination was the most effective among the various combinations tested. The study involved extracting the explants: the leaf, cotyledon, stem, root, callus of the leaf, and cotyledon of S. marianum L. The extraction process used a hexane solvent to remove fat. An ethanol solvent for phenolics separation after hexane was applied to the same sample. The high-performance liquid chromatography (HPLC) results showed that all the explants contain various phenolic compounds. The antibacterial activity has also been identified at 200 µg/mL concentrations against four pathogenic bacterial strains: Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus by using the agar dilution method. The results showed significant cotyledonary leaf callus extract showed antibacterial activity, notably against E. coli, with a zone of inhibition measuring 31 mm. These extracts were also used as antioxidants. The root extract has antioxidant activity with a percentage of 79.0%. These extracts and their compounds could be used as a natural antioxidant and antibacterial source. As we unravel the full potential of plant tissue culture and the conventional antibiotics and antioxidants become less effective and the side effects of synthetic compounds rise, exploring plant-based solutions like those from the tissue culture of S. marianum could provide valuable and eco-friendly alternatives, and contribute to developing novel therapeutic agents from natural sources.

Abstract

This research aims to obtain biodiesel by transesterification of coconut oil with MgO/SiO2 as a catalyst, with the objective to examine the effect of MgO loads on the performance of the catalysts expressed in terms of oil conversion. The MgO/SiO2 composites with different mass ratios of 1:1, 1:2, 1:3, 1:5, and 1:10 were synthesized from Mg(NO3)·6H2O and SiO2 extracted from rice husk silica using sol-gel method and followed by calcination at 800 °C for 6 h. The produced catalysts were then tested in the transesterification of coconut oil to investigate the effect of catalyst composition, oil to methanol ratios, and reaction times. The experiments were carried out using a fixed catalyst load of 10% oil (w/v) and at 70 °C. The catalyst with the highest performance was then characterized by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to confirm the formation of crystalline MgO/SiO2. The highest conversion of the transesterification product was analyzed using gas chromatography-mass spectrometry (GC-MS) technique to confirm the biodiesel production. The XRD diffractogram of the synthesized sample is characterized by the presence of sharp peaks confirming the existence of the sample as crystalline material attributed to the pyroxene-ideal (MgO3Si) phase. The existence of the sample as crystalline material is also supported by the absence of a broad diffraction peak attributed to amorphous rice husk silica, and SEM image of the sample which is characterized by the visible existence of crystalline structure in the forms of platelet prismatic, and tetrahedral shaped structures. The results demonstrated that the highest conversion (98%) was achieved with the use of MgO/SiO2 (1:5) as a catalyst, a ratio of oil to methanol of 1:6, and a reaction time of 4 h. The formation of methyl esters was confirmed by the results of GC-MS analysis.

Abstract

Plasmonium falciparum dihydrofolate reductase-thymidylate synthase (PfDHFR-TS) is one of the most crucial antimalarial targets. Mutations in the binding pocket of this target lead to resistance to the antifolate. The mutations influence the amino acid residues at points 51, 59, 108 and 164 and contribute significantly to malaria not being treated well. Priority should therefore be given to the development of antifolate-resistance drugs. These studies aim to investigate new 4-benzyloxy-2-trichloromethylquinazoline derivatives as PfDHFR-TS inhibitors using QSAR, ADME, drug-likeness, toxicity, molecular docking studies, and molecular dynamics simulations. The best equation model from the QSAR analysis used MLR and PLS statistics to show that the pIC50 is linearly related to GATS4e, SpMax AEA(ed), and Mor28e, but inverted when compared to ATS6m and ATSC7m. The predictive ability of the model was confirmed by internal and external validation. In addition, the Y-randomization validation showed that the QSAR model was reliable, robust, and stable, with a cRp2 score of over 0.5. ADME and drug-likeness predictions confirmed the new QSAR design for molecules S10, S23 and S64. Based on the toxicity results, three molecules are expected to have moderate and non-toxic properties, starting with S23 and then S10 and S64. Molecular docking studies show that all three molecules have high binding energies, 9.869, 9.589, and 9.565 kcal/mol. The amino acid residues Leu46, Asp54, Ser111, and Thr185 play a major role in ligand-receptor interaction in the binding pocket of quadruple mutant PfDHFR-TS. Furthermore, an evaluation of molecular dynamics simulations of three complexes S10-3JSU, S23-3JSU and S64-3JSU demonstrated stable interactions over 100 ns.

Abstract

Hyrtios sponge is known to possess alkaloid compounds that may exhibit in vitro activity against Plasmodium falciparum. The aim of this study was therefore to isolate and characterise the antiplasmodial active compounds of Hyrtios sp. Sponges collected from the island of Podang-Podang, South Sulawesi, Indonesia. In addition, the LC-HRMS analysis was performed on the active fractions of methanol and ethyl acetate extract to evaluate their antiplasmodial activity. We also validated the in silico antiplasmodial activity of PfDHFR-TS with molecular docking, pharmacokinetics, drug likeness, toxicity, and molecular dynamics analysis. The molecular docking studies showed that the synthesized extremes would have high binding affinity to PfDHFR-TS, thus confirming their potential as powerful enzyme inhibitors. Moreover, the pharmacokinetic and drug-likeness calculations showed that all compounds met the requirements for sufficient resistance and bioavailability, indicating potential as therapeutic candidates. The results of the toxicity analysis indicated that the compounds had a relatively good safety profile, but some potential adverse reactions in the renal and cardiac vasculature could not be excluded. Molecular dynamics simulations confirmed that the complexes formed between the ligand and the target were stable, and the low RMSD value indicated that the active site interactions were also quite stable. These observations reinforce the notion that the extract from Hyrtios sp. not only shows remarkable antimalarial activity but also exhibits pharmacological properties of a prospective drug candidate, which encourages further work in the development of malaria combination therapy both in clinical assessment and comprehensive mechanism of action investigation.

Abstract

This study addresses the critical need for effective glucose level measurement in managing diabetes mellitus (DM). DM is a serious, economically influential disease that has no cure at present, highlighting the magnitude of prevention, control, and monitoring of blood glucose levels. This study systematically examined 79 articles from Google Scholar and PubMed databases, focusing on non-invasive glucose measurement using the photoacoustic system. After eliminating duplicates, 27 articles were reviewed. Glucose solution was predominantly used as the primary sample. Fixed and tunable lasers, especially near-infrared (NIR) lasers, were highlighted due to their superior penetration and accuracy in glucose measurements. Signal-purification techniques were used to guarantee accurate detection by removing noise. The evaluation involved regression analysis and machine learning integration to determine glucose levels statistically. The choice of sampling sites in volunteers was a critical factor affecting measurement accuracy. The study demonstrated meaningful progress in the development of photoacoustic methods, particularly in monitoring DM.

Abstract

Drug analysis in biological samples remains a significant challenge due to the complex matrix composition that can interfere with extraction and detection processes. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method, initially developed for pesticide residue analysis, has been increasingly adapted for forensic toxicology, particularly in drug extraction from biological matrices. This review explores various modifications of the QuEChERS method applied to blood, urine, and liver samples, focusing on the effectiveness of different solvents, buffer salts, and sorbents in enhancing extraction efficiency. Furthermore, it highlights current challenges such as matrix effects and the critical importance of method validation to ensure reliability and reproducibility. By analyzing recent developments and trends in QuEChERS applications, this review offers valuable insights into optimizing extraction protocols for forensic purposes. The findings aim to support the advancement of more efficient, robust, and accessible analytical techniques in forensic toxicology, ultimately contributing to more accurate and reliable drug detection in complex biological samples.
