Abstract

Palm oil is one of the keys to the Indonesian economy and the main commodity for attracting foreign investment. The palm oil and palm kernel industry generates most of the foreign currency from palm oil. The price of palm oil often goes up and down every month resulting in instability in the income received by people who own oil palm plantations. The aim of predicting palm oil prices is to carry out appropriate planning or steps for palm oil business actors. One way to overcome this problem is to make predictions. One method that can make predictions is the Extreme Learning Machine (ELM). ELM is an artificial neural network method used to predict palm oil prices. The ELM method is a feedforward method with a single hidden layer which is better known as a single hidden layer feedforward neural network (SLFNs). In this research, the best implementation was 5 inputs with 20 neurons in the hidden layer with output in the form of palm oil price predictions. Based on the tests carried out, the research produced the smallest error rate of 0.0027111424247658633 using 20 neurons in the hidden layer so that the latest data prediction test results for 5 price rotations in September rotation 1 were 1400.314191, September rotation 2 were 1846.798921, September rotation 3 amounted to 1505.430419, September rotation 4 amounted to 2301.853412, September rotation 5 amounted to 2645.082489 in palm oil price predictions.

Abstract

The pyrazole scaffold modification in various chemical structures on several studies has shown various biopharmacological activities. This study aims to predict the potential inhibition of pyrazole analogs derived benzene-sulfonylurea (4A, 4B, 4E, 5A, 5C, 5D) against the α-glucosidase (3A4A) and aldose reductase (3RX2) enzymes based on a molecular docking approach using Molecular Operating Environment (MOE) 2020.0102 software and evaluate pharmacokinetic profile (ADMET). In this study, the six test compounds were obtained from previous studies that have been proven antihyperglycemic. The results showed that all the 3,5-disubstituted benzene-sulfonylurea derivative pyrazole analogs are predicted to have low inhibitory activity against the α-glucosidase enzyme. Further, all compounds showed good aldose reductase inhibitor activity and had lower binding free energy values ​​than tolrestat as the positive control (-6.82 kcal/mol). Compound 5C has the best potential inhibitory activity against the aldose reductase enzyme compared to the other test compounds, because it has the lowest binding free energy value (-8.76 kcal/mol) and interacts with important residues on the receptor forming four hydrogen bonds, namely the carbonyl group of SO2 with residues Trp111 and His110, and the carbonyl group of the amide with residues His110 and Tyr48, as well as 3 hydrophobic bonds, namely a pyrazole ring with residues Leu300, Trp219 and a furan ring with Phe122. ADMET properties of the compounds are also predicted. This information provides an opportunity for a 5C compound as an aldose reductase inhibitor agent to develop drug candidates with better and safer activities.

Abstract

Turbofan engines are crucial components in the aviation and manufacturing industries, where estimating the Remaining Useful Life (RUL) has a significant impact on operational efficiency and safety. This study aims to predict the RUL of turbofan engines using the Support Vector Regression (SVR) method, a machine learning approach that has proven effective in modeling nonlinear relationships between variables. Operational data related to turbofan engines include operational parameters, sensors, and maintenance records. The initial stage of this research involves data analysis based on unit number, time, operational control, and sensor parameters. This process begins with preprocessing to initialize the initial data values, normalize, and select sensors that have stagnant values, as these sensors do not affect the machine learning system. Subsequently, regression calculations are performed to compare predicted values and actual values using the Support Vector Regression method optimized with Grid Search Optimization. In this study, testing was conducted with Parameters C [1, 10, 50, 100] and ε [1, 5, 10, 50], resulting in the best model with an RMSE error of 19.56 and MAE of 14.73.

Abstract

This study developed interactive learning media using Macromedia Flash to enhance Occupational Health, Safety, and Environmental Awareness (K3LH) instruction within the Basic Electronics curriculum in vocational high schools. The research employed a Research and Development approach guided by the 4D model (Define, Design, Develop, and Disseminate) to produce a validated multimedia learning product aligned with the Merdeka Curriculum. During the Define stage, needs assessment and learner analysis revealed low student engagement and conceptual difficulties with electronics safety topics, underscoring the need for technology-based instructional innovation. The designed media integrated text, visuals, animations, audio, and interactive assessments to support autonomous and student-centred learning. Expert validation involving material and media specialists resulted in high validity scores of 94.7% and 94.8%, indicating strong curriculum alignment, conceptual clarity, interface organisation, and language quality. Field testing with Grade 10 Electronics Engineering students yielded a practicality score of 85.1%, confirming that the media was easy to operate, pedagogically relevant, visually engaging, and effective in supporting understanding and participation. These outcomes demonstrate that Macromedia Flash-based learning media remain highly functional for vocational classroom environments, particularly where technological infrastructure is limited. The study concludes that the developed media can serve as a robust instructional tool to strengthen student motivation, improve comprehension of K3LH concepts, and enrich technology-enhanced learning in vocational electronics education. Future research is recommended to expand implementation across different school contexts and migrate the product to modern digital platforms to improve scalability and accessibility.

Abstract

ABSTRACT. Pyrazoline is a well-known group of five-ring heterocyclic compound containing two nitrogen atoms that has a wide range of promising biological activities. The aim of this research is to synthesize 1,3,5-triaryl-2-pyrazoline derivatives with chloro substituent and pyrrolidine moiety and to explore their potency as inhibitors for cervical cancer. The synthesis was performed through three-steps reactions. Firstly, synthesis of chlorinated naphthalenyl chalcones through Claisen-Schmidt condensation. Secondly, synthesis of chlorinated naphthalenyl pyrazolines through nucleophilic addition of phenylhydrazine to the chalcone and followed by intramolecular cyclization. Thirdly, synthesis of pyrazoline derivatives by adding the pyrrolidine moiety through O-alkylation reaction. Then, the in silico studies through molecular docking, ADME profiling, and toxicity prediction were performed to explore the potency of the synthesized compounds as inhibitors of cervical cancer by inhibiting the activity of Sirtuin-1 (SIRT-1) (PDB ID: 4I5I). The structure of all pyrazoline derivatives (4a-4c) were confirmed by spectroscopic analysis including UV, FT-IR, HRMS, and NMR. Based on the docking study, compound 4a with binding free energy of -12.59 kcal/mol exhibited better potency as SIRT-1 inhibitor than previously reported inhibitor (EX527). Then, based on the ADME profiling and toxicity prediction, it can be concluded that compound 4a exhibited reasonable drug properties with low toxicity potency (predicted LD50 = 1000 mg/kg). Keywords: : Cervical cancer, molecular docking, pyrazoline-pyrrolidine, pyrazoline synthesis, sirtuin-1
