Coastal erosion caused by strong wave impacts has led to land loss and poses a threat to public facilities. Therefore, a project was initiated to develop a detailed construction plan for coastal protection, serving as a guideline to safeguard the area from further erosion. Located in Kuala Kampar District, Pelalawan Regency, Riau, this coastal region is experiencing severe erosion in several critical areas, characterized by unique hydrodynamic conditions due to the Bono phenomenon (strong tidal currents).
Several surveys were conducted to support project planning, including topographic, bathymetric, soil mechanics, hydrology, and socio-economic surveys. These aimed to assess coastal conditions, tidal dynamics, and the project’s impact on the local community. Based on the findings, key coastal protection measures were proposed, such as breakwaters to dissipate wave energy, revetments for direct shoreline protection, jetties to manage sedimentation, and groins to reduce sand movement and prevent erosion. The project is expected to mitigate coastal erosion, enhance community safety, and create job opportunities while addressing challenges like sedimentation, ecosystem shifts, and workforce development for local labor involvement.
Recently, mining activities in the Bodri River, especially in the river area, have become increasingly concerning. Of course, if left unchecked, this will damage the river body, river channels, cause degradation of the river bed which can result in landslides of river embankments and river buildings and other buildings in the river.
Mining is carried out by local communities traditionally in the dry season or by entrepreneurs using heavy equipment (back hoe). Miners in the Bodri River do not yet have permits. Based on the above, the extraction of mining commodities in the Bodri River causes environmental damage.
The river area in the form of river boundaries is severely damaged. This condition is very disturbing to the surrounding community, the environment and ecosystem are damaged. On the one hand, traditional mining benefits the community because it is a source of income during the dry season, on the other hand, the ecosystem and environment are damaged if mining is carried out using heavy equipment without following the correct procedures.
Based on the results of data collection, compilation and analysis of regulations, territorial and technical analysis related to the planning area in the Bodri River, the following main conclusions can be identified: 1. The results of field inventory activities throughout the scope of this zoning activity, found that there were seven transverse/longitudinal buildings, including: 5 bridges, 1 check dam and 1 weir. The river facilities and infrastructure that were damaged were: ❖ Kali Putih Check Dam was built in 2017 and experienced damage to the check dam wall in 2019. Where ± 90 meters upstream and ± 60 meters downstream of the check dam building there were mining activities. ❖ Gabion upstream of the Singorojo Bridge was built in 2020 and was damaged in 2022. Where ± 400 meters downstream of the gabion building there were mining activities. ❖ Singorojo Bridge experienced erosion/landslides on the riverbank under the bridge. Where ± 325 meters downstream of the Singorojo Bridge there are mining activities.
2. From 11 (eleven) observation points, mining activities were found that did not have permits. These activities are in the form of manual extraction and also involve heavy equipment such as excavators and transport trucks.
3. Based on data from the Energy and Mineral Resources (ESDM) Service of Central Java Province in 2023, it is known that there are permit holders located on the Bodri River (in the study area). Including 3 IUP holding companies that are in the exploration permit stage and 2 companies are in the reserve permit stage.
4. Manual mining and heavy equipment until now still cause damage to river walls and cliffs and cause changes in river morphology, including erosion and sedimentation in several places.
Based on the analysis, there are quite significant changes in river morphology or flow based on a comparison of the digitization of the Bodri River trough boundary in 2015 with aerial photo mapping in 2023. Based on the results of the overlay analysis of the Bodri River trough boundary in 2015 with aerial photo mapping in 2023, it is known that there is a change in the river trough boundary of 4,322 meters in length, a change in the shift in the width of the river ranging from 2 meters to 250 meters (which has exceeded the width of the river boundary) and a height/thickness ranging from ± 2 meters. 6. The potential rate of sediment potential in the Bodri Watershed is 447,203.74 tons/year. This material is a general input to the sedimentation balance in the Bodri River (study segment 24.5 km), while the Suspended Load Discharge based on the calibration of laboratory sample test results for one year is 300,624.58 tons/year where this result is the sedimentation input of the Bodri River at the activity location. 7. The results of observations and interviews in the field show that the estimated volume of excavation/mining in the form of sand and stone is estimated at 576,700 tons/year, where this result is the output of sedimentation of the Bodri River at the activity location. This value includes observation points and also mining locations, including. 8. Based on the geological review and field observations, it can be concluded that mining materials in the form of sand and stone come from the right and left of the riverbank that has experienced landslides. This is because the Bodri Watershed does not produce sand and stone material input as volcanic products. 9. Based on the multicriteria analysis, it can be seen that the level of river damage, both in the river body and on the riverbank, shows moderate and severe damage due to mining, both manual mining and using heavy equipment, so that it is not allowed to carry out material/mining activities in the Bodri River planning area from the Lutut River in Kaliputih Village, Singorojo District to the Bodri River in Puguh Village, Pegandon District. In addition, the damaged condition of the river body and boundaries cannot recover naturally due to mining activities in the Bodri River.
Based on the Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 28/PRT/2015 concerning the Determination of River Boundary Lines and Lake Boundary Lines, the boundary line on the Bodri River is set at a width of 100 m on the right and left of the riverbed. 11. The results of the analysis of flood inundation with annual Q50 at the study location (segment length 24.5 km) showed that in general the area of flood inundation is within the boundary line (100 m on the right and left from the edge of the riverbed). However, several agricultural lands, plantations, and residential areas located within the river boundaries are potentially affected by flooding.
As part of a commitment to sustainable water resource management, this project aims to assess the operational performance of river infrastructure and develop the Actual Needs for Operations and Maintenance (AKNOP) to enhance the efficiency and effectiveness of river management. Covering the City of Manado, Minahasa Regency, and North Minahasa Regency, this project focuses on 15 key rivers that play a crucial role in the regional hydrological system and flood mitigation efforts.
The implementation involves a data-driven and technically comprehensive approach, including infrastructure inventory, institutional assessment, hydrological and topographical surveys, and physical condition mapping of river facilities. Leveraging modern technology and strict technical standards, each stage of the assessment is conducted systematically to generate strategic recommendations that can be effectively implemented.
This project adheres to the latest regulations, including UU No. 17 of 2019 on Water Resources, as well as technical guidelines from the Ministry of Public Works and Housing (PUPR) of Indonesia regarding river operations and maintenance. The key deliverables include a River Operations and Maintenance Performance Assessment Report, Operations & Maintenance Manual, Cost Budget Plan (RAB), as well as visual documentation and thematic maps, serving as primary references for optimizing river infrastructure management.
A multidisciplinary approach and synergy with various stakeholders are the keys to ensuring that the proposed recommendations effectively address future challenges in river management. With a fact-based analysis and measurable methodologies, this project is expected to make a tangible impact on enhancing the efficiency of river operations and maintenance across Indonesia.
Keuliling River is one of the sub-basins of the Krueng Aceh Watershed which has a large water potential to increase the provision of raw water in order to meet the water needs of Banda Aceh and Aceh Besar. Based on the study of the development of the Krueng Aceh watershed in 1996, the construction of the Keuliling Reservoir, in addition to meeting the water needs for irrigation of the Krueng Aceh Extension and Krueng Jreue covering an area of 3,159.30 Ha, can also support the increase in the area of rain-fed rice fields into technically irrigated rice fields, namely the Keuliling Hilir District covering an area of 1,053 Ha, and the Keuliling Hulu District covering an area of 578.20 Ha. In addition to raw water and irrigation, the Keuliling Reservoir can be used as an alternative location for sports facilities, including rowing while maintaining the eligibility criteria in accordance with applicable standards.
The location of the Keuliling Reservoir Rehabilitation Supervision Work is located in Cot Glie District, Aceh Besar Regency, Nanggroe Aceh Darussalam Province, which is ± 35 km from the center of Banda Aceh towards Medan and can be reached by four-wheeled vehicles within 1 hour.
In the landscape arrangement of Keuliling Reservoir, it refers to the applicable rules and regulations as discussed more fully in the Landscape Report. In addition, it also takes into account existing conditions in the field and the results of coordination and discussions with related parties, especially the directors of the work and the Keuliling Reservoir Dam Management Unit (UPB) as the manager. Several conclusions that can be drawn from the Keuliling Reservoir landscape arrangement plan are:
1. There is a disposal area for landfills that have been leveled with heavy equipment around the Keuliling Reservoir pool as a result of excavation/dredging work in the reservoir pool and on the land edge of the reservoir pool that is being prepared for venue of PON XXI September 2024. For this reason, it is necessary to arrange the landscape of the disposal area for tourism, sports and greening purposes.
2. Arrangement of the Keuliling Reservoir landscape planned in disposal areas 1 and 2, namely:
– Alternative 1 (there are supporting buildings), with the concept of tourism, interactive playgrounds for children, water tourism (shallow) and sports, which are equipped with supporting building facilities such as toilets, prayer rooms, culinary huts.
– Alternative 2 (without supporting buildings), with the concept of agrotourism, only landscaping by planting fruit trees that are grouped according to their type into their respective zones. Equipped with complementary tourism facilities in the form of buildings for prayer rooms and toilets.
3. Arrangement of the landscape of the UPB Office complex and UPB House Keuliling Reservoir, where in addition to the arrangement of the garden/yard, there is also the addition of 1 UPB mess unit with a capacity of 5 rooms for UPB guests/employees.
4. Landscaping of the existing mushalla area of Keuliling Reservoir with improvements to the appearance of the mushalla by adding a facade around it (adopted from the Baiturrahman Grand Mosque in Banda Aceh) and arranging a garden in the mushalla area. 5. Landscaping of disposal areas 3, 4 and 5 which are designated for greening and agrotourism, because the location can currently only be reached by boat.
The Ministry of Public Works and Public Housing (PUPR) of the Republic of Indonesia in this case, the Directorate of Water Resources, one of its functions is to carry out the construction of Water Resources facilities and infrastructure in the field of implementing water source networks to support the construction of coastal protection construction facilities.
