Abstract

Acetylsalicylic acid is an analgesic drug that still popularly used. However, acetylsalicylic acid may result undesirable side effect of gastrointestinal as it can cause gastric ulcer to bleeding. Previous research has succeeded synthesizing new compound derived from salicylic acid, namely 4-(chloromethyl)salicylic acid which has the potential to reduce its side effects with a better pharmacological effects than acetylsalicylic acid. In its development, the formulation of the compound in tablet dosage form has been carried out. However, until now there has not been a pharmacological test to determine whether it still provides a greater effect than acetylsalicylic acid after being formulated. This study is to test the analgesic activity of 4-(chloromethyl)salicylic acid tablets in albino mice using writhing test and hotplate methods. Analgesic activity test using the hotplate method was carried out on albino mice which given the suspension of the tablet sample and the observations were made in a periodic of time. Analgesic activity test using writhing test method was carried out in 0.6% acetic acid-induced albino mice, where the suspension of the tablet was administered 30 minutes before administration of acetic acid. Analgesic activity was assessed by counting the number of writhings, and the results were statistically compared with one-way ANOVA. Tests were also performed on acetylsalicylic acid as a positive control and suspension as a negative control group.  There were significant differences (P<0.05) of the analgesic activity observed among groups. Both methods show that 4-(chloromethyl)salicylic acid tablets provide stronger analgesic activity than acetylsalicylic acid.

Abstract

The utilization of solar energy is commonly achieved through solar panels; however, heat dissipation from the panels often reduces their overall efficiency. A hybrid system combining solar panels and thermoelectric generators (TEGs) offers a potential solution to this issue. To enhance the temperature difference (∆T) across the TEG, a metal plate can be added to the hot side, while a heatsink is applied to the cold side. This study investigates the performance of three prototype configurations: a 2.4 Wp monocrystalline solar panel integrated with a TEG module, with variations in the addition of a copper plate, an aluminum plate, and no plate on the TEG hot side. Experimental results demonstrate that the prototype with a copper plate yielded the highest average values, with a ∆T of 8.63 °C, voltage of 11.57 V, current of 0.17 A, and power output of 2.02 W. In comparison, the aluminum plate prototype achieved a ∆T of 6.11 °C, voltage of 11.57 V, current of 0.16 A, and power output of 1.71 W, while the prototype without any plate produced a ∆T of 5.80 °C, voltage of 10.79 V, current of 0.15 A, and power output of 1.63 W. Among all tested configurations, the copper plate prototype exhibited superior performance, attributed to the high thermal conductivity of copper, which significantly enhances the ∆T across the TEG, thereby increasing electrical output.

Abstract

Dibenzalacetone and their derivatives, , 4,4’ dihydroxydibenzalacetone are curcumin analogs that have antioxidant activity. The effect of hydroxyl group on the synthesis reaction is proven by comparing the synthesis results yield of dibenzalacetone with 4,4’-dihydroxydibenzalacetone. Both compounds are synthesized through the Claisen-Schmidt condensation reaction using sodium hydroxide as the catalyst. The synthesis results were tested for purity by melting point tests and thin layer chromatography, and structure identification tests were carried out using infrared spectrophotometry. The results of the study showed that the percentage yield of dibenzalacetone was greater than 4,4’-dihydroxydibenzalacetone, which was 67.29% and 24.51%, respectively. The presence of hydroxyl groups can increase the density of the benzene ring and facilitate the reaction of the carbonyl group of 4-hydroxybenzaldehyde, including the Cannizaro reaction. The Cannizaro reaction can occur in aldehyde compounds without alpha hydrogen, such as benzaldehyde, where some of the aldehyde will undergo oxidation and some will undergo reduction. As a result, the amount of aldehyde that reacts with acetone decreases so that the yield obtained is lessthan dibenzalacetone. Antioxidant testing was carried out using the DPPH method and expressed as an IC50 value, then compared with curcumin and vitamin C. Although it does not show greater antioxidant activity than curcumin or vitamin C, the presence of hydroxyl groups in 4,4' dihydroxydibenzalacetone can increase antioxidant activity compared to dibenzalacetone which does not have a hydroxyl group. This is proven by the IC50 value of the compound 4,4'-dihydroxydibenzalacetone which is lower than dibenzalacetone, which is 3.9588 mM and 66.5503 mM, respectively.

Abstract

The Semarang-Demak Toll Road was constructed as a strategic component of the Indonesian government's initiatives to enhance regional connectivity and promote economic development in Central Java. Nevertheless, this endeavor not only generates intricate social and environmental consequences, but also generates economic advantages. The objective of this investigation is to identify and evaluate the social, economic, and environmental consequences of the toll road's construction. The study will concentrate on social inequality, population migration, changes in settlement patterns, and environmental degradation, including erosion, inundation, and pollution. The multidimensional approach that simultaneously integrates social, economic, and environmental analysis in the context of large-scale infrastructure development is the unique feature of this study. This approach has not been comprehensively investigated in the case of the Semarang-Demak Toll Road. Quantitative and qualitative methodologies are implemented, which encompass surveys, in-depth interviews, field observations, and secondary data analysis. The research sample was purposively selected from the community, local economic actors, and policy makers along the toll corridor. The study's findings suggest that while toll road construction can enhance economic development and accessibility, it also has negative repercussions, including decreased environmental quality, changes in spatial planning, and social inequality. Therefore, a mitigation strategy is required in the form of sustainable development, community involvement, and inclusive government policies to ensure that economic benefits are equitable and that social and environmental aspects are not sacrificed. This research is a significant contribution to the development of sustainable and equitable infrastructure development policies.

Abstract

This study discusses designing and implementing an RGB color pattern recognition system using the Support Vector Machine (SVM) method on a 4-DoF robotic arm to perform autonomous object transfer tasks. This system integrates computer vision, artificial intelligence, and trajectory planning technologies to improve the adaptability and precision of the robot manipulator's movements. The pattern recognition process is done through image acquisition using a camera mounted on a support pole, then extraction and normalizing color values in the R, G, and B channels. These RGB values are input features for color pattern classification using SVM with Radial Basis Function (RBF) kernel and regulation parameter C = 100. The training results show that the SVM model can classify three color classes (red, yellow, and blue) with an accuracy rate of 100%. The classification data is then used to control the movements of three robots with red, orange, and blue arms, each tasked with picking up and moving objects of the corresponding color. The robot trajectory was planned using the Cubic Trajectory method, which produced smooth and coordinated movements between joints, with an average task completion time of ±10 seconds. Based on the results of 30 trials, the system showed a success rate of 96.67%, with only one failure due to gripper position inaccuracy. The results of this study indicate that the combination of the SVM and Cubic Trajectory methods can improve the efficiency and accuracy of robotic arm systems in color-based object recognition and manipulation, which has the potential to be applied to artificial intelligence-based industrial automation systems.
