Guest Lecture at the FMIPA Chemistry Department Presented Ari Setyono, Pertamina Offshore Pipeline Practitioner

The Chemistry Department, FMIPA UNEJ, held a guest lecture presenting Ir. Ari Setyono, Pertamina offshore pipeline practitioner (17/5). Ari has experience working for several large oil companies overseas as a pipeline engineer. “The material will be more about my personal experience when working abroad; we can compete with foreign workers in the fields we are good at,” said the ITS Mechanical Engineering alumnus. We are told about installation techniques and pipe maintenance, which involve chemistry, namely corrosion. “At the beginning, I will introduce pipe installation techniques, and later, the part that will be interesting for chemistry students is about corrosion,” he continued.

Ari explained in general how the pipe is located on the seabed, how to install it, and how to maintain the stability of the pipe by having to know about soil studies, soil compression, and the process when approaching the beach. “Apart from installation, we must also pay attention to pipe protection from other elements, such as shipping lanes and port areas with lots of anchors that could endanger the pipe route,” he explained. Protection related to chemistry, namely corrosion, is discussed, including the form of loss and the rate of corrosion. The discussion was interesting because, in chemistry, there was a course that dissected corrosion. Through this guest lecture, it can attract interest so that there will be a return to the corrosion chemistry course.

Previously in his speech, the Head of the Chemistry Department, FMIPA, Prof. Dr. Anak Agung’s wife Ratnadewi, S.Si., M.Sc., invited students participating in guest lectures to actively participate and take advantage by asking questions of the presenters. “Our lectures are not only on campus but also by inviting company practitioners, especially Pertamina, which is related to our field of chemistry,” she said. Prof. Dewi said that chemistry can also work in the oil sector, not only in the mining or petroleum sector. It is said that practitioner lectures like this will also provide input for study programs.

Moderated by Suwardiyanto, S.Si., M.Si., Ph.D., who was a colleague of the presenter while studying abroad, it gave participants the opportunity to ask several questions. The participants’ interest in the offshore sector made the presenters talk about the prerequisites for being able to work there. “Everyone can have the opportunity to work offshore, of course, with special prerequisites such as physical strength and mental strength, such as being able to stand loneliness,” joked the man from Ponorogo. However, there are also several other parts of the petroleum sector that require alumni from chemistry.

One of the lecturers who taught chemistry courses, Tri Mulyono, S.Si., M.Si., asked what the role of corrosion is in the oil industry, especially pipelines. Ari Setyono answered that the oil industry really needs experts in the field of corrosion. “I have a friend who is a corrosion expert and who is a woman from the Jember area who might be invited to share stories about the connection between corrosion and petroleum,” he answered. It is also possible in the future to establish collaboration with the Chemistry Study Program in the form of student internships by seeing the enthusiasm of the participants in this guest lecture.
