Many factories in the Medan Metropolitan Area are reducing their production scales or providing their own generators against the unstable power supply condition by PT. Perusahaan Listrik Negara (PLN). It means that the shortage of power and energy supply has seriously influenced the economic activities in North Sumatra, and consequently, it became one of the bottlenecks of economic growth.
The power development plan prepared by PLN shows that a serious power shortage occurred in the North Sumatra power system in 2007-2009 since the 11 planned power stations have faced some difficulties except for three projects under execution. Under such circumstances, the feasibility study conducted in 1981-1982 was reviewed and updated in 2004.
Consequently, the type of development scheme was reformed to a run-of-river type as a clean energy development project so that the project could achieve, without losing its original viabilities, the reduction of financial burden, mitigation of social environment impacts, and contribution to the Clean Development Mechanism (CDM) policy.
Lake Tawar and Peusangan River hydropower potential development aims at restructuring the present diesel-dependent power generation. Detailed design was performed in 1994 with OECF fund, and the construction supervision (CS) contract was made in 1996 with OECF and ADB fund. However, the situation of Aceh Special Province had worsened, and CS was stopped due to the reason mentioned above.
In 2007, loan agreement was made with JBIC once again. This project aims to mitigate the tight power supply situation and improve the stability of power supply in the Aceh-North Sumatra power system by constructing a hydroelectric power plant and related transmission lines near Lake Tawar in the upstream of the Peusangan River.
This will lead to an improved investment climate and thereby contribute to economic development in the northern region of Sumatra Island. Moreover, the project will contribute to lowering the burden placed on the global environment by using renewable energy.
This project aims to strengthen the port logistics capacity of the Jakarta Metropolitan Area and improve the total economic activities in the region by constructing an international seaport and access roads in Patimban, which is in the eastern metropolitan area.
The project consists of the construction of two international container terminals (-4.0 m, L = 421 m), one car terminal (L = 308 m) (including breakwater, revetment, dredging, reclamation, and other port-related facilities), and the installation of necessary navigation aid facilities as main components of the project’s east connecting bridge (L = 1,005 m). The project owner is the Directorate General of Sea Transportation, Ministry of Transportation, and Nippon Koei carried out detailed design and construction supervision services (2018-2024).
The Tanjung Priok Access Road was originally planned to connect the Jakarta Outer Ring Road to the Tanjung Priok International Port. However, it is now planned to be part of the Jakarta Outer Ring Road to replace the northeast section that has been set aside due to land acquisition and resettlement issues.
The project has the following essential functions: to avoid serious traffic congestion thereby contributing to sustainable urban activities; to supplement the functions of radial toll roads and the Cengkareng Access; to enhance the physical distribution originating from Tanjung Priok International Port; to support the improved land use in the JABOTABEK area; and to install a Traffic Surveillance System (TSS) on toll roads.
Tanjung Priok Port is the largest international port in Indonesia and it manages 55% of container traffic in the country. With the increase in cargo throughputs and calling ship sizes, the port has been suffering serious traffic congestion in the navigation channel and basins and in the port’s inner roads. Under these circumstances, a JICA Study Team was dispatched to prepare the master plan of the port.
In the 2003 master plan study, the scope of this project focused on 1) channel and basin improvement, 2) relocation of breakwaters, and 3) inner port road improvement. This project aims to increase the efficiency of vessel traffic by widening and deepening the ship lane, and this will enable the port to meet increasing vessel traffic in the coming years and increase its function as an international hub port.
Gunung Kidul Regency has been suffering from serious water deficiency in the dry season. Only 30% of inhabitants can access safe water since this area is affected by karst tableland. In addition, water outage occurs 8 days out of 10 days in the dry season and many inhabitants are forced to use unsanitary water from a river and shallow wells, which makes several people contract diseases such as diarrhea.
Improving sanitation maintenance of water supply facilities is the most critical issue in the area. Under these circumstances, the Government of Indonesia has asked Japan to provide grant aid to improve the water supply facilities, to teach the operation of facilities, and to improve the operation and maintenance capacity. This project aims to realize a constant and safe supply of water to 93,800 residents and to free the community from water-drawing labor.
To restore the natural coral sandy beaches, beach management and maintenance are required. The restored sandy beaches contribute to the sustainability of the tourism industry in Bali.
The objective of this project is to achieve sustainable beach management and coastal disaster risk reduction through beach restoration and conservation plans, such as sand nourishment, structural measures, and support for beach maintenance and management activities, to contribute to promoting the tourism sector, regional economic development, and climate change adaptation in Bali Island.
The Solo River is the longest river in Java Island. It collects rainwater from a catchment area of 16,000 km2 and drains into the Java Sea north of Surabaya. The basin is topographically divided into three sub-basins: the Upper Solo River basin, the Madiun River basin, and the Lower Solo River basin. The Lower Solo River basin, covering around 12% of Java Island, has a concentrated population. It contains many of the country’s most important industries and lies in a geographically important region adjacent to the nation’s second largest city of Surabaya.
The Lower Solo River has been one of the most important water resources for the region and has supported the region’s economic development. However, the Lower Solo River has frequently brought floods to the basin. The project aims at an overall integrated basin development for both flood control and water resources development to contribute to the stabilization of public welfare and to accelerate agricultural activity and economic development at the national and regional levels.
The objective of the project is to increase the production of rice and other crops in the Rentang Irrigation Area in the Cimanuk watershed by modernizing and rehabilitating the existing irrigation system and improving the operation and maintenance of the irrigation system, thereby contributing to sustainable food security in Indonesia.
To this end, a combined approach is proposed for implementation, with "infrastructure improvement components”, such as upgrading of irrigation infrastructures, supported by "soft components", such as modernization support program (MSP) including asset management program, irrigation water management, and agriculture support.
The MAMMINASATA Metropolitan Area consists of Makassar City, one of the seven largest cities in Indonesia in terms of population (1.2 million in 2002), and the surrounding districts of Takalar, Maros, and Gowa. The Study Area sustains economic activities in Sulawesi Island and plays the role of a long-distance transportation hub in Eastern Indonesia.
The MAMMINASATA Area has been developed in a less coordinated manner, causing inefficient land use and disorder in development planning. In 2003, a provincial legislation called the “Guideline on Spatial Planning for MAMMINASATA Metropolitan Area” was enacted. On the other hand, the Act for Spatial Planning is under revision, and the Ministry of Public Works is preparing a guideline for regional spatial planning under the principle of decentralization (Otonomi Daerah).
To support the Government of Indonesia (GOI) in having an Integrated Spatial Plan for the MAMMINASATA Area, JICA is undertaking the Study in close cooperation with concerned relevant authorities of GOI.
The objective of this project is to develop a comprehensive design for an industrial park in the Subang area (2,100 ha), a mixed-use development comprising industrial, residential, commercial, and public facilities with a "Smart & Sustainable" concept. This area connects Jakarta to West Java and Central Java provinces, making it a strategic location. This industrial park will be accessible via numerous major transportation infrastructures.
The master plan for the industrial park in Subang has been prepared by the client, with the original idea of developing a green andself-sustaining industrial urban city as Nippon Koei’s reference to conductingservices for this project.
