South Kalimantan Regional Overview
📌 South Kalimantan is a province in Indonesia on the island of Kalimantan with an area of $3,750,000 \text{ m}^2$ and a population of nearly four million people.
💎 Natural resources like coal, timber, rubber, rattan, and palm oil remain the main economic drivers in the province.
🌊 The Barito River estuary serves as the vital shipping lane for entering Banjarmasin's general port.

Historical Challenges in Barito River Dredging
🗓️ Between 1975 and 1976, the Ministry of Transportation dredged and maintained the Barito channel using state budget (APBN) funds, but the effect only lasted about three months.
📉 High sedimentation rates caused the channel to quickly become shallow again, forcing ships to wait for high tide, which only allowed passage for 6-8 hours daily.
🚫 The Ministry of Transportation stopped allocating APBN funds for dredging the Barito estuary starting in 2008.

Establishment and Operations of PT Ambangbaritonusapersada
🤝 In 2003, the South Kalimantan Provincial Government obtained a concession authority from the Ministry of Transportation to manage a new Barito River shipping lane.
🏢 The Provincial Government established PT Ambangbaritonusapersada in cooperation with PT Pelabuhan Indonesia 3 (Persero) to specifically manage the Barito estuary.
🛠️ This company was founded to construct, dredge, manage, maintain, and collect fees for the estuary services, following a new channel design based on a 1997 study.
🚀 The dredging of the new Barito River channel officially began on June 13, 2018, and was completed by the end of November 2008, followed by a one-month trial in December 2008.

Company Vision and Technical Specifications
🎯 The company's vision is to provide satisfactory service in managing the Barito estuary and supporting facilities to boost the economy of South and Central Kalimantan.
🚢 The goal is to achieve a channel depth of $-50$ meters (MLLW) with a bottom width of 100 meters and a bottom length of 15,000 meters.
⚓ This upgraded channel allows for 24-hour passage in both directions for ships with a draft of less than 5 meters.
🏅 PT Ambangbaritonusapersada operates under the motto "Pelayanan Prima dan Kerjasama yang Baik" (Excellent Service and Good Cooperation).

Key Points & Insights
➡️ The Barito River estuary is crucial for the economy of South and Central Kalimantan, but historical maintenance efforts failed due to high sedimentation.
