NUNUKAN, KOMPAS.com - Indonesia is particularly focusing on its border with Malaysia along the estuary of the Sei Ular river in North Kalimantan province's Nunukan regency, after Malaysian authorities repeatedly nabbed Indonesian nationals for illegally crossing the border.
Indonesian officials went to Sei Ular last Wednesday to see the maritime boundaries firsthand.
The officials came from the National Border Management Agency (BNPP), the Ministry of Foreign Affairs (Kemenlu), the Ministry of Home Affairs (Kemendagri), and the Coordinating Ministry for Political, Legal and Security Affairs (Kemenko Polhukam)
"[BNPP] are cooperating on an inter-agency, as well as on the transnational level to resolve the issue of illegal crossings," said BNPP Assistant Deputy for Maritime and Air Borders Siti Metrianda.

"BNPP and the Ministry of Foreign Affairs will coordinate with Malaysian and Indonesian maritime forces, as well as the Indonesian Consulate in Tawau, Malaysia. We will mitigate the number of border crossings whle we resolve the roots of this complex problem."
Taking geography into account
Siti hoped the Indonesian consulate in Tawau can explain to Malaysian authorities that the border crossings are a misunderstanding.
"The shallower part of [Sei Ular] is on the Indonesian side of the border, while the deeper end of the estuary is in Malaysia. The tide naturally goes with the deeper water, leading travelers to the Malaysian side," Siti added.
"These geographic factors should be taken into consideration by Indonesian and Malaysian maritime security personnel."
Siti noted that the North Kalimantan provincial administration and BNPP personnel in Nunukan have sound procedures to prevent Indonesian travelers on the estuary from getting caught by their Malaysian counterparts.

"The Indonesian authorities limited boat traffic on the river from 7 am in the morning to 5 pm in the evening, local time. Outside these hours, motorists must request for an escort from maritime security forces, such as the Navy and water and air police unit (Pol Airud)," Siti said.
BNPP also fully supports the building of a monitoring post in Sei Ular. "The monitoring post is a good solution, because it can prevent Indonesian citizens from involuntarily straying to the Malaysian side [of Sei Ular]," she asserted.
However, Siti noted that the path of least resistance is best taken for Indonesian nationals who run into Malaysian authorities at the border. "If one came into contact with Malaysian border patrols, do not try to flee," she explained.
