Baliase Irrigation Network Supports Agriculture in Indonesia
The development of irrigation networks is one of the components supporting the success of agriculture.
By Agung Rahmadi, Project Manager
In addition to maintaining and managing water sources, the development of irrigation networks is one of the components supporting the success of agricultural development. The Baliase
Irrigation Area is a potential area. It has land resources (agriculture) and water resources (irrigation water) to be developed into an irrigation area with a technical irrigation network.
In September 2016, the Baliase Irrigation Network, South Sulawesi, was approved for a project contract on the results of a Joint Operation (KSO) between Hutama Karya (Persero), Citra Mandiri Abadi, and Entolu Buana Mandiri. Four years later, the Baliase Irrigation Network began construction on the initiative of the Ministry of PUPR through the Pompengan Jeneberang River Basin Center (BBWSPJ), Directorate General of Water Resources (SDA).
The construction and rehabilitation of irrigation networks is a priority program of the Ministry of PUPR to support sustainable agricultural production. The Baliase Dam and Irrigation
Network are one of the National Strategic Projects (PSN) listed in Presidential Regulation 56 of 2018. The Baliase Irrigation Area is in Masamba, Mappadeceng, Sukamaju, Baebunta, and Malangke, North Luwu Regency.
The cost for the construction of the Baliase irrigation network is Rp. 297 billion, Hutama Karya carries out this project with the scope of work covering; landfill and excavation, procurement and installation of precast concrete cast precast concrete floors, water gates, to public facility buildings which include official houses and guard houses.
The Baliase Irrigation Network will help productivity in the agricultural sector by providing 60.99 km of secondary canals,
40.70 km of canals, irrigation buildings, and bridges. The irrigation canal on the right side two will benefit an Irrigation Area (DI) of 5,567 ha. In implementing this project, one thing that received special attention was the landfill work in the borrow area. In other words, the success of this project depends on the level of success of the landfill work on the borrowed land area because it has a pareto value of 55%.
Hutama Karya in Development of Baliase Irrigation Network
As in other projects, the project has its challenges. The challenge encountered during construction was the lengthy land acquisition process, which resulted in the inability to carry out frontal embankment work in one segment. Therefore, an alternative
to the initial plan is to maximize work on free land and lease the land of residents yet to be free so that it can be traversed as access to stockpiles.
In addition, the location of the quarry stockpile and the work location is 20-30 km away. This impedes the work because it requires a large fleet. As a result, the increase in the price of diesel fuel results from the high use of diesel fuel. The solution is to backfill work with a supply system by the supplier. Thus the cost of diesel is the responsibility of the supplier.
The weather factor is also a challenge. Masamba is different from other locations in Indonesia, with the rainy season almost evenly distributed throughout the year. In 2020, Masamba became one of the six regional sub-districts in the North Luwu district affected by flash floods. The peak of the rainy season occurs between January and August. Therefore, maximizing work during sunny weather by increasing working hours at night is one of the policies that must be taken.
With the operation of this irrigation network, Hutama Karya also hopes to help reduce public concern due to routine flooding every rainy season. As well as supporting sustainable agricultural production in South Sulawesi, which is one of the national food storages. With the construction of the Baliase Irrigation Network, unproductive community lands can be used as rice fields, and annual flooding in estuary areas can be reduced by having a drainage channel.
