Introduction

North Sumatra Province, as one of the largest provinces in Indonesia, has a vast population of 13,766,851 people (Source: BPS Population of North Sumatra Province in 2015). This figure reflects a significant need for adequate electricity supply to support the daily activities of the community. Therefore, the construction of power plants is necessary to meet these needs. The Indonesian government has also emphasized the importance of utilizing local energy sources, especially renewable energy sources, as stated in Law No. 30 of 2007 concerning Energy. One of the potential renewable energy sources in this area is hydro energy from river flow.

Background of the Study

The Langkat Regency in North Sumatra Province has a vast river flow, which can be utilized as a source of hydro energy. The river flow has a significant potential to generate electricity, and this study aims to investigate the feasibility of constructing a macrohydro power plant in the Langkat Regency river flow. The study will focus on the geographical and hydrological conditions of the river, as well as the potential benefits of developing a micro hydro power plant in the area.

Methodology

The F.J. Method was used to calculate the mainstay debit as a comparison value. This method requires rainfall data, evaporation, and water catchment areas. In addition, Flow Duration Curve (FDC) was used to determine the discharge in accordance with the probability of 90%. The calculation results using the F.J. Method showed a plan discharge of 5.19 m³/dtk. Furthermore, the analysis of the carrier channel design produced a square-shaped dimension with a width of 4 m and a height of 2 m, as well as a 34.99 m penstock pipe.

The Potential of Hydro Energy in the River of Berbail

Geographical and hydrological conditions in Langkat Regency strongly support the development of micro hydro power plants. With adequate rainfall, adequate river flow, and supporting topographic characteristics, river Berkil is an ideal location for the development of this renewable energy. The use of micro hydro power plants is very efficient, especially in increasing electricity access in rural areas that are difficult to reach by conventional electricity networks.

Benefits of Micro Hydro Power Plants

Developing a micro hydro power plant in the river not only meets the electricity needs of the community, but also provides various other benefits, such as:

Energy Sustainability: This generator utilizes renewable natural resources, so it is more environmentally friendly compared to fossil-fueled plants.
Improved Local Economy: With the availability of adequate electricity supply, various small and medium businesses can develop, encouraging local economic growth.
Community Empowerment: The development of this project can involve the local community, create jobs, and improve their skills in managing energy resources.
Reduction of Fossil Energy Dependence: By developing renewable energy, dependence on fossil energy sources can be reduced, thereby reducing the negative impact on the environment.

Results and Discussion

Based on the results of research and analysis conducted, it can be concluded that the river in Langkat Regency has a large potential as a source of micro hydro power plants. With a plan debit of 5.19 m³/sec and the resulting power reaches 747.82 KW, this project can make a significant contribution in meeting the needs of the electrical energy of the community. The implementation of this project not only has the potential to increase electricity access, but also strengthen the sustainability of local energy and economy in North Sumatra Province.

Conclusion

In conclusion, this study has demonstrated the potential of the Langkat Regency river flow as a source of hydro energy. The results of the study have shown that the river has a large potential to generate electricity, and the development of a micro hydro power plant in the area can provide various benefits, including energy sustainability, improved local economy, community empowerment, and reduction of fossil energy dependence. Therefore, it is recommended that the government and local authorities consider the development of micro hydro power plants in the Langkat Regency river flow to meet the needs of the community and promote sustainable development.
