International Joint Symposium - Direktorat Riset dan Pengabdian kepada Masyarakat

Introduction

Various natural disasters have occurred nowadays, many infrastructure buildings have been affected, especially in areas that have problematic soil and geoenvironmental problems. This joint symposium was initiated to be a forum for discussion and sharing regarding geotechnical and geo-environmental aspects as well as multi-mitigation efforts when natural disasters occur. It is expected that this activity can establish good collaborations and friendship between the Japanese Geotechnical Society, JGS (Kyushu Branch) and the Indonesian Geotechnical Society, HATTI (East Java Branch). Participants who are expected to attend are not only academicians but also for the younger researchers and engineers, as well as practitioners.

Porong Mud Volcano

The Sidoarjo mud flow (commonly known as Lumpur Lapindo, wherein lumpur is the Indonesian word for mud) is the result of an erupting mud volcano in the subdistrict of Porong, Sidoarjo in East Java, Indonesia that has been in eruption since May 2006. It is the biggest mud volcano in the world; responsibility for the disaster was assigned to the blowout of a natural gas well drilled by PT Lapindo Brantas, although company officials contend it was caused by a very distant earthquake that occurred in a different province. [wikipedia.org]

At its peak it spewed up to 180,000 cubic metres (6,400,000 cu ft; 240,000 cu yd) of mud per day. By mid August 2011, mud was being discharged at a rate of 10,000 cubic meters (13,000 cu yd) per day, with 15 bubbles around its gushing point. It is expected that the flow will continue for the next 25 to 30 years. Although the Sidoarjo mud flow has been contained by levees since November 2008, resultant floodings regularly disrupt local highways and villages, and further breakouts of mud are still possible. [wikipedia.org]

New mudflows spots begun in April 2010, this time on Porong Highway, which is the main road linking Surabaya with Probolinggo and islands to the east including Bali, despite roadway thickening and strengthening. A new highway is planned to replace this one however are held up by land acquisition issues. The main railway also runs by the area, which is in danger of explosions due to seepage of methane and ignition could come from something as simple as a tossed cigarette. [wikipedia.org]

The mud retaining levee at point P-67 had experienced a subsidence of five meters with a length of around 100 meters in October 2018. This condition makes residents who live around the embankment concern that the levee will fail at any time and water mixed with mud will overflow into residential areas. The Sidoarjo Mud Control Center (PPLS) began repairing the Lapindo mud embankment which experienced a decline at point P 67 in Gempol Sari Tanggulangin Village, Sidoarjo on the week after.
