Gowa, Indonesia, 6 apr 2026/afmrg/Imagine being on a ship in the middle of the ocean when suddenly the power system fails. Lights go out, navigation systems stop, and safety is at risk. Surprisingly, one of the smallest components—the bearing inside a generator—can trigger such a dangerous situation. But thanks to recent research, a simple yet powerful solution is emerging.
Gowa, Indonesia, 5 apr 2026/afmrg/What if the humble pandan leaf—commonly used in kitchens for its fragrance—could help power our homes? This idea is no longer just imagination. Recent scientific research shows how natural materials like pandan leaves can play a role in creating eco-friendly solar energy technology.
Gowa, Indonesia, 3 apr 2026/afmrg/What if one of the world’s most troublesome aquatic plants and one of its most persistent plastic wastes could be combined into a powerful solution for sustainability? This is exactly what a recent scientific study চেষ্টা to explore—transforming environmental problems into innovative materials that could benefit society.
GOWA, Indonesia Apr 3 2026/AFMRG/In many developing regions, electric tricycles are emerging as an affordable and eco-friendly transportation solution. They help reduce fuel dependency, lower emissions, and improve mobility for communities with limited access to conventional transport. However, behind this promising innovation lies a critical question: how safe and durable are these vehicles? A recent scientific study explores this issue by analyzing how electric tricycle frames respond to static loading—essentially, how strong and reliable the structure is when carrying weight.
GOWA, Indonesia Apr 1 2026/AFMRG/In modern manufacturing, precision is everything. From car engines to industrial machines, the quality of each component depends on how well it is made. A recent study published in the Journal of Physics: Conference Series reveals how improving machining processes—specifically milling—can make a big difference. The article, titled “Investigation of Surface Roughness and Tool Wear in Milling of AISI 4340 Steel,” was published on April 1, 2024, by ISAIME-2022. It explores how cutting tools wear down over time and how this affects the smoothness of metal surfaces.
GOWA, Indonesia Apr 1 2026/AFMRG/In the world of manufacturing, small changes can create big impacts. One such example comes from a recent study published in the Journal of Physics: Conference Series , titled “Effect of Welding Time Variation in Resistance Spot Welding on Mechanical Properties of Dissimilar Joints on Mild Steel and AISI 304 Stainless Steel.” Released on April 1, 2024, by ISAIME-2022, this research explores how adjusting welding time can significantly influence the strength and durability of metal joints.
GOWA, Indonesia Apr 1 2026/AFMRG/Roads are more than just pathways connecting places—they are lifelines of economic activity, education access, and social interaction. Yet, the materials used to build these roads can significantly impact the environment. One promising innovation in this field is polymer-modified asphalt, a technology that enhances road durability while reducing environmental harm. Understanding how this works does not require a technical background—just a closer look at how science improves everyday infrastructure.
GOWA, Indonesia Jan 8 2025/AFMRG/As a maritime country, Indonesia has a large and diverse maritime and marine economic potential. Therefore, the shipping industry plays an important role in managing this potential. Ship construction is very dynamic, operating in motion with its cargo, making the ship construction affected by dynamic loads with very large fluctuations and frequencies.

Fabrication and characterization of Dye-Sensitized Solar Cells (DSSCs) utilizing natural dyes of purple sweet potato, Ipomoea Batatas L., (PSP) and papaya leaf, Carica Papaya, (PL) have been investigated. A single dye and a mixture of the two dyes (Cocktail) were used to make solar cells. The sandwich structure of DSSC consists of dye-coated semiconductor TiO2 deposited on conductive glass by doctor blades as the working electrode and carbon layer on the conductive glass as the counter electrode. The research was conducted to determine the effect of the ratio of the mixture (3:1, 1:1, 1:3) and the effect of immersion time (12, 24, 48 hours) of dye mixture between purple sweet potato anthocyanin dye and papaya leaf chlorophyll dye on the efficiency of DSSC. The final test was carried out by measuring voltage and current using a multimeter while illuminating the cell with a 20 Watt LED as a light source. The test results obtained higher and more stable voltage and current on DSSC with dye cocktail PSP: PL ratio 1:3 than DSSC with dye cocktail ratio 1:1, ratio 3:1. Meanwhile, in the variation of immersion time, the result produced by DSSC with a 48 hour immersion time shows higher and more stable voltage and current compare with DSSC with a duration of immersion of 24 hours and 12 hours. In conclusion, the highest efficiency was obtained in the variation of the mixture ratio of PSP:PL 1:3 with an immersion time of 48 hours and 0.607% of efficiency.
