MARI BELAJAR "METODE PELAKSANAAN PEKERJAAN BENDUNGAN"

Summary

The transcript highlights the construction of the Way Sekampung Dam in Pringsewu, Lampung, Indonesia. The dam, funded by the national budget, aims to supply water for irrigation and hydropower in nearby cities. The project involves several contractors and consultants, with a focus on building the main dam, its intake structures, and pipelines. The construction includes detailed geological and technical planning, such as tunneling and embankment methods. Challenges, such as project delays and the need for high-quality materials, are discussed, alongside measures for long-term maintenance to ensure the dam's functionality.

Takeaways

• 😀 The Way Sekampung Dam project is located in Pringsewu, Lampung, Indonesia, and aims to supply water, irrigation, and hydropower (PLTA) to various regions including Bandar Lampung, Metro, and Lampung Selatan.
• 😀 The project is funded by the Indonesian National Budget (APBN) with a total of 1.895 trillion IDR, and involves several contractors including PT Waskita Karya, PT Adhi Karya, and PT Indra Karya.
• 😀 The dam's construction includes the development of a main dam structure and the Way Sekampung intake building, designed to address the geographic and topographic conditions of the site.
• 😀 The Way Sekampung Dam features a tunnel shaped like a horseshoe to adapt to the local topography, with phases involving drilling, explosive material insertion, and excavation work.
• 😀 The dam construction employs various methods for soil compaction and embankment, including clay and gravel layers, to ensure stability and long-term functionality.
• 😀 The project also focuses on the installation of pressure meters, shear testing for the embankment, and ongoing monitoring and maintenance of its components and pipeline network.
• 😀 Technical challenges include managing the construction timeline and addressing delays in the project, as well as ensuring proper operation and maintenance of the dam's intake and other structures.
• 😀 A key focus of the project is ensuring the durability and reliability of the pipeline network, using high-quality materials to ensure longevity despite limited maintenance.
• 😀 The Way Sekampung Dam project is divided into two primary focuses: the dam body and the pipeline network, each requiring specialized construction and monitoring techniques.
• 😀 The project is expected to contribute significantly to regional water supply, irrigation, and energy production, helping to meet the needs of the surrounding areas in Lampung Province.

Q & A

What is the primary purpose of the Way Sekampung Dam project?

The primary purpose of the Way Sekampung Dam project is to supply raw water, provide irrigation, and generate hydroelectric power (PLTA) for the cities of Bandar Lampung, Metro, and the Lampung Selatan Regency.

How much funding was allocated to the Way Sekampung Dam project?

The project was funded by the Indonesian government through the national budget (APBN) with an allocation of 1.895 trillion Rupiah.

Who are the key stakeholders involved in the project?

The key stakeholders in the project include the Ministry of Public Works and Public Housing (Kementerian PU PR), PT Waskita Karya, PT Adhi Karya, PT Indra Karya (the planning consultant), and PT Tata Gunakan Iya (the supervision consultant).

What is the design of the Way Sekampung Dam's main structure?

The main structure of the Way Sekampung Dam is designed as a rock-fill dam, with a core made of clay and a national soil-type cover, tailored to suit the geographic and topographic conditions of the location.

What is the unique feature of the tunnel in the project?

The tunnel in the project is designed in a horseshoe shape to accommodate the geographic and topographic features of the location, which includes hills and uneven terrain.

What are the stages involved in the tunnel construction?

The tunnel construction involves several stages, including preparation work, drilling, explosive material insertion, blasting, air supply and lighting, excavation disposal, and site cleaning and surveying for coordinate and elevation control.

What methods are used for the dam's embankment construction?

The embankment construction utilizes several methods, including clay embankment for the core, fine filter embankment, coarse filter embankment, and rockfill embankment in different zones to ensure proper compaction and stability.

What is the focus of the second phase of the project?

The second phase of the project focuses on the technical and managerial aspects, including evaluation of work volumes, addressing delays in project completion, and maintaining the intake structure and operational systems.

What factors are important for the maintenance of the piping system in the project?

The maintenance of the piping system is crucial, with an emphasis on selecting high-quality pipes to ensure longevity and functionality, even without ongoing maintenance.

What are the monitoring and observation measures for the project?

The project includes several monitoring and observation measures, such as the installation of instruments like pressure meters and shear force sensors on the dam body, along with ongoing inspection and maintenance for the intake structure and surrounding components.
