Abstract

Bagasse is one of the solid wastes of the sugar cane industry, and it contains lignin fibre. Lignin from sugarcane bagasse is also known to have relatively high antioxidant activity. Sugarcane bagasse antioxidants can stabilize free radicals by completing free radicals’ lack of electrons and inhibiting chain reactions from forming free radicals. This type of research is laboratory experimental research (actual experiment design). In this research, lignin isolation and fractionation will be carried out from sugarcane bagasse to obtain lignin fractions with antioxidant activity. The percentage of lignin yield from this process is around 72.85%. The IR spectrum resulting from isolation from sugarcane bagasse has a typical absorption peak of aliphatic and aromatic –CH at a wave number of 2919.7/cm. The antioxidant activity of the lignin fraction from sugarcane bagasse was determined using the DPPH (1,1-diphenyl-2- picrylhydrazyl) free radical scavenging method using four solvents, namely ethyl acetate, acetone and methanol. Based on the level of antioxidant strength, the strength level is 50 powerful, 50-100 strong, 100-250 medium, 250-500 weak and 500 inactive; therefore, the results of testing the most potent antioxidant activity in the acetone fraction were found to be ??50 50, 6755 mg/L and weak antioxidant activity was found in the methanol fraction, the result was ??50 68.8503.

Abstract

The welding process plays a crucial role in manufacturing and is inseparable from its advancement. Deutsche Industrie Norman (DIN) defines welding as creating a metallurgical bond at the joint of metal or alloy metals in their molten state. This process is essential for constructing strong, durable materials like plates, steel, and pipes. Bending tests, including face bend and root bend, are often conducted to evaluate the quality of welded joints. These tests assess welded materials’ toughness, strength, and resistance under specific loading conditions. This study employed two welding techniques: Gas Metal Arc Welding (GMAW) and Shielded Metal Arc Welding (SMAW). GMAW, called Metal Inert Gas (MIG) welding, uses argon or helium as protective gases and a continuously fed electrode wire. On the other hand, SMAW relies on flux-coated electrodes to create the weld seam, with molten metal from both the electrode and parent material filling the joint. The results revealed distinct advantages for each method. The highest bending test value for the root bend was achieved with MIG welding at 982,55 Kgf/mm², demonstrating its effectiveness in creating durable root joints. Conversely, SMAW exhibited superior performance in face bend tests, achieving a bending strength of 104111 Kgf/mm², making it ideal for surface-level joint applications. Both techniques displayed no visible cracks in their welds, ensuring compliance with industry standards and confirming their reliability for various manufacturing needs. These findings highlight the importance of selecting appropriate welding methods based on specific application requirements.

Abstract

High-volume fly ash (HFVA) in cement mortar has gained attention due to its potential to reduce environmental impact and enhance sustainability. However, HVFA mortar often exhibits reduced initial compressive strength compared to conventional mortars. Incorporating carbon nanotubes (CNT) and Graphene oxide (GO) has been shown to enhance the mechanical properties and microstructure of the mortar, which can overcome the shortcomings of HVFA. This study investigates the effect of CNT and GO on compressive strength and cement hydration of HVFA mortar. This study used fly ash as a 60% cement replacement, with 0.01% CNT and GO contents of 0.01%, 0.02%, 0.03%, 0.04%, and 0.05%. Compressive strength tests were performed at 3, 7, and 28 days of curing. The results showed that adding CNT and GO improved the compressive strength by 15.4% over the control mortar at 0.01% CNT and 0.03% GO. Most importantly, incorporating CNT and GO mitigated the typical reduction in initial compressive strength, with around a 15% increase observed at 3 and 7 days compared to the control mortar. The cement hydration characteristics were analyzed using X-ray diffraction (XRD), which revealed the presence of various crystallization phases, including calcium silicate hydrate (C-S-H), calcium aluminate silicate hydrate (C-A-S-H), quartz, portlandite, calcium carbonate, and ettringite. Adding CNT and GO to HVFA mortar significantly enhances its mechanical properties. It promotes the formation of complete chemical bonds in the cement hydration process, improving the mortar's overall performance.

Abstract

Plants are essential to human beings because plants are considered most as foods. Plants can be used for food ingredients, medical purposes, and industrial applications. People inspect plants using traditional methods, such as using the naked eye, which can be time-consuming and expensive. Therefore, the effectiveness and high quality of automated crop identification classification systems are needed for adequate crop protection. This study aims to identify and classify nine plant species using different datasets, focusing on transfer learning from models trained on plant leaf datasets. Most research has shown that increasing the dataset size would significantly improve classification accuracy. The accuracy of the first test using the modified N1 classification model was 99.45%. In the second experiment, the accuracy of the N2 model was 99.65%. The accuracy of the N3 model, despite being slightly less accurate than AlexNet, was 99.55%, and it performed better, while the accuracy of AlexNet was 99.73%. Compared to the AlexNet model, the proposed model performed better and required less training time. The N1 model reduced the training time by 34.58%, the N2 model by 18.25%, and the N3 model by 20.23%. The N1 and N3 resulted in the same size, namely 14.8MB, and the compactness was 92.67%. The size of the N2 model was 29.7MB, and the compactness was 85.29% compactness. The proposed models provide more accuracy and efficiency in classifying plant leaves and can be used as a standalone mobile application that benefits farmers.

Abstract

Final-year students face significant financial challenges due to limited income and low financial literacy. This often leads to uncontrolled spending, lack of awareness about financial habits, and imbalanced income and expenses. This study proposes a rule-based financial management system to help students organize, monitor, and analyze their finances. The analysis shows that students' main expenses are food, transportation, and housing, with financial risks arising from irregular financial recording and overspending. The proposed system includes features like expense categorization, budget limits, monthly reports, notifications for unusual spending, and reminders to record finances. Applying a rule-based approach, the system offers personalized recommendations, such as budget control for specific categories and early warnings for disproportionate expenses. This application aims to improve financial awareness, help students prioritize spending, and reduce financial risks. It also serves as a financial education tool to support students in achieving financial stability as they transition into professional life.
