Analisis Alokasi Air Wilayah Sungai Siak

---

The Siak River Basin is a strategically important region in the national
context, known for its abundant water resources that are vital for fulfilling basic
and other water-related needs. The utilization of water in the Siak River Basin
encompasses activities such as swamp irrigation, drinking water supply,
industrial processes, and plantation operations. However, conflicting interests
between upstream and downstream stakeholders, as well as among various water
users, can lead to disputes over water usage. Furthermore, the availability of
water in the area is progressively diminishing. Therefore, it is imperative to
establish a water allocation management system to prevent potential water
shortages in the Siak River Basin. This research aims to achieve two objectives:
[1] analyzing the water balance in the Siak River Basin, and [2] developing a
comprehensive water allocation plan that considers the specific characteristics
and priorities of individual water users. Additionally, the study aims to identify
both utilized and untapped water resources to ensure effective and sustainable
management practices.
The research employed quantitative and analytical-descriptive methods to
analyze water allocation based on the water balance and prioritize water user
needs. Secondary data, including rainfall data, river water level data, water user
technical recommendations from BWSS III, and the catchment area size of the
river basin obtained from the ArcGIS application, were utilized in this study.
The results of the water allocation analysis in this study revealed that based
on the Q80 value, there are 3 nodes, namely node 22, node 45, and node 47, out
of the total 69 nodes representing 4 water users, experiencing water deficit during
dry years. However, the water balance during normal and wet seasons indicated a
surplus of river water at the water extraction locations, which is sufficient to meet
the water users' needs. Therefore, water allocation is necessary during dry years
due to the water deficit observed in certain periods. The allocated water
discharge for the four water users experiencing deficits are as follows: node 22
(PT. Subur Arum Makmur) allocated 0.045 m3/s, node 45 (PTPN V Lubuk
Dalam) allocated 0.253 m3/s, PTPN V PKS Lubuk Dalam allocated 0.0186 m3/s,
and node 47 (PT. Kimia Tirta Utama) allocated 0.0157 m3/s. Although the overall
water balance shows a surplus condition, it is essential for river management
authorities to regulate the implementation and conduct comprehensive evaluation
in water allocation planning and implementation.
