Jakarta, January 15, 2026 — PT Intan Pertiwi Industri (INTIWI) officially presented prizes to representatives of the Mechanical Engineering Student Association of Jakarta State University (HMTM UNJ) as part of the INTIWI x HMTM UNJ Article Competition series held from December 8, 2025 to January 10, 2026.
The awarding of these prizes is intended to be passed on to the winners who have contributed the best writings about the world of welding and product applications, with the final results as follows: 1st Place Hadi Aji, 2nd Place Rahmadi, and 3rd Place Miki.
Through this agenda, INTIWI together with HMTM UNJ wants to encourage the young generation of mechanical engineering to not only be strong in theory, but also be able to convey technical ideas in a coherent, relevant, and impactful manner for industrial needs.
This activity provides a space for students to hone their analytical, writing, and understanding skills in real-world welding applications.
For INTIWI, the participants' work is an important first step in building a stronger culture of technical literacy in Indonesia.
List of Winning Articles in the INTIWI x HMTM UNJ Article Competition
The following articles about the winners can be read on the official INTIWI website:
1st Place: Hadi Aji
In the article “LB-52-18 Reliable Low Hydrogen Welding Electrode for Modern Infrastructure”, LB-52-18 is discussed as an AWS A5.1 E7018 classification low hydrogen electrode that is relevant for modern infrastructure needs, especially when welding high strength steels that are sensitive to hydrogen cracking (HIC) and toughness issues in the HAZ.
The article emphasizes that the selection of a consumable such as LB-52-18 is an engineering decision that directly impacts the reliability of the connection in critical projects.

2nd Place: Rahmadi
Through the article “KOBE-7010S Performance Analysis for Carbon Steel Pipe Welding”, Rahmadi reviews the performance of KOBE 7010S for carbon steel pipe welding with a focus on the vertical down welding method that pursues high efficiency and productivity.
KOBE-7010S is described as an AWS E7010 cellulose electrode designed to optimize downhill welding, with the typical characteristics of E7010 such as deep penetration and easy slag removal, while addressing the challenges of hydrogen induced cracking risks in cellulose electrodes.

3rd Place: Miki
In the article “Performance Analysis of HF-500 Hardfacing Electrode for Heavy Industrial Components”, Miki highlights hardfacing as a proactive strategy to reduce abrasion losses on components.
HF-500 electrode welding electrode is positioned for moderate to severe abrasion applications, with a target hardness of approximately 500 HB, and is addressed through a microstructural and “performance matrix” approach including limitations such as low corrosion resistance and moderate impact resistance.

These three articles demonstrate a strong technical approach, application understanding, and a presentation style that is easy for readers to understand, especially for industrialists, welders, and engineering students.
A Glimpse of the INTIWI x HMTM UNJ Article Competition
This article competition carries the spirit of:
“Work with precision, seize opportunities with inspiring work.”
INTIWI organizes this program as a form of commitment to expanding relevant welding education and opening up opportunities for real collaboration between industry and academia.
Vision
Improving national welding standards.
Mission
- To be a platform for young talents.
- Delivering relevant education.
- Encourage collaboration between industry and academia.
- Collaboration between Industry and Academics for Indonesian Welding
INTIWI believes that the progress of national welding standards depends not only on technology and products, but also on the quality of human resources, learning culture, and the connection between industrial needs and education.
Through this article competition, students not only learn theory, but also learn to construct arguments, read application requirements, and convey technical insights that can serve as references for a wider readership.
Closing
The award ceremony on January 15, 2026, marks the point that this program is not just a competition, but the beginning of a collaborative effort to build a stronger welding education ecosystem.
INTIWI congratulates the winners: Hadi Aji, Rahmadi, and Miki. Thank you to HMTM UNJ and all participants who contributed their excellent work.
See you in the next collaboration program.
