DYNAMIC OF CHANGING AREA OF SUSPENDED SOLID BY UTILIZING LANDSAT 8 OIL IMAGES IN LAKE SINGKARAK, WEST SUMATRA PROVINCE, 2017 and 2022

TSS is suspended materials (diameter > 1 µm) retained on a millipore filter with a pore diameter of 0.45 µm. TSS consists of silt and fine sand and micro-organisms. The main cause of TSS in waterways is soil erosion or soil erosion that is carried into water bodies. If the TSS concentration is too high, it will inhibit the penetration of light into the water and result in disruption of the photosynthesis process (Effendi in Lestari, 2009:4). Many activities cause turbidity that affects the penetration of sunlight into water bodies, so it can hinder the process of photosynthesis and primary production of waters. Turbidity usually consists of an organic particle originating from watershed erosion and resuspension from the lake bottom. Keywords : Normalized Difference Vegetation Index, Normalized Burn Ratio, Landsat 8, Severity Level of Forest and Land Fires. Based on the results of the study, researchers have obtained TSS values ​​in 2017 and 2022 at Lake Singkarak with the Landsat 8 image data processing method using the Syarif Budiman algorithm with several stages, namely first combining image data bands from band 1 to band 7 then cropping which serves to determine the area to examine then performs masking which functions to separate land from water and then enter the Syarif Budiman algorithm formula then classify the TSS values ​​in Lake Singkarak. It can be seen that the predicted TSS concentration has not been too much different from the TSS concentration in the field. researchers have obtained TSS values ​​in 2017 and 2022 at Lake Singkarak with the Landsat 8 image data processing method using the Syarif Budiman algorithm with several stages, namely first combining image data bands from band 1 to band 7 then cropping which functions to determine the area which will be examined then do masking which functions to separate land from water and then enter the Syarif Budiman algorithm formula then classify the TSS values ​​in Lake Singkarak.

There is a correlation of variables of education (p=0.011), knowledge (p=0.000), availability of facilities (p=0.000), supervision (p=0.018) with community actions. Factors that have a significant relationship with community actions in disposing of household waste in Lake Singkarak Ombilin are the level of education, knowledge, availability of facilities, and supervision. It is recommended that the local government improve supervision of community actions and providing supporting facilities, create written regulation, and impose penalty of community actions in disposing of household waste.

Disaster mitigation through oral stories: a case study around Singkarak Lake

This study describes the disaster mitigation strategy around Singkarak Lake, Solok, and Tanah Datar District West Sumatra through the oral stories of ecological sites. Disaster management in Indonesia seems to ignore local memories contained in oral stories because they are considered myths. This study is an attempt to investigate how people build knowledge of disasters and how they understand disasters by utilizing the oral story of their environmental ecological sites. It is qualitative research in which the data for this study are collected by using the participant observation method. Besides, the interview with the local community as the source of data is also done. The results of the study indicate that the communities have an oral story on ecological sites. They believe in the contents of the story as truth and follow it as part of the social structure. The communities know and realize that they live in disaster-prone areas so the taboos and advice contained in the oral stories are agreed upon as oral norms to always maintain the balance of nature in their environmental landscape. Pilgrimages and salvations are routinely held at the graves of village leaders as a part of building togetherness and loyalty to the ancestors.

Vulnerability of endemic bilih fish Mystacoleucus padangensis Bleeker, 1852 in Lake Singkarak, West Sumatra, Indonesia

Bilih fish (Mystacoleucus padangensis) is an endemic species in Lake Singkarak, West Sumatra, Indonesia. It has high economic value, rich in nutrition and as an export commodity. Bilih dominated the catch in Lake Singkarak. The excessive fishing causes fish population decline. There has been an indication of stock decrease and overfishing exploitation status. Fisheries management needs to carry out to maintain the sustainability of bilih fish. This study was conducted to determine the vulnerability status of bilih fish as an information for bilih fish management. Data analysis was carried out using Productivity and Susceptibility Analysis (PSA). PSA is a semiquantitative risk assessment method used to assess the impact of fisheries on fish stocks. Based on 11 productivity and 12 susceptibility attributes, this study was conducted. The results showed that the vulnerability index was in the high category (v=2.1) and the productivity parameter value (p=1.3) lower than the susceptibility value (s=2.3), indicating bilih status is vulnerable to over fishing and need to be maintained.

Occurrence of organochlorine residues in surface water and mussel Corbicula sumatrana from Lake Singkarak, West Sumatera

Organochlorine is a synthetic pesticide that has been banned in many countries because of its high persistence in the environment and can accumulate in animals. The goal of our study was to determine the level of organochlorine residues in surface water and in the mussel Corbicula sumatrana of Lake Singkarak. Water and mussel samples were collected from 10 sampling sites of Lake Singkarak, Batu Taba, Sumpur, Guguk Malalo, Ombilin, Tikalak, Sumani, Saniang Baka, Muaro Pingai, Paninggahan, and Tanjung Mutuih, respectively in June 2021. Water and mussel samples were extracted and analyzed with gas chromatography. The result of our study revealed the occurrence of Lindan (7 μg/L) in the surface water of Tikalak, and also Aldrin (3 μg/L) in the surface water of Tikalak, Sumani, and Ombilin. Organochlorine residue compounds were also detected in mussels of five sampling sites (Tikalak, Sumani, Muaro Pingai, Paninggahan, and Tanjung Mutuih). Mussels of Tikalak contain compounds namely Dieldrin, Dichlorodiphenyltrichloroethane (DDT), and Endosulfan with levels of 2 μg/kg, 6 μg/kg, and 3 μg/kg, respectively. Dieldrin was also detected at Sumani (2 μg/kg), Muaro Pingai (4 μg/kg), and Paninggahan (10 μg/kg). DDT was also detected at Tanjung Mutuih at a level of 3 μg/kg. Other compounds such as Heptachlor and Endrin were not detected both in surface water and in mussel from all sampling sites studied. The results indicate that organochlorine residue can still be found in the environment, with its level in mussels being higher than in surface water.

Microplastic pollution in the surface water of Lake Singkarak, Indonesia

Microplastic pollution is already at an “alarming” level in Indonesia’s marine and freshwater ecosystems. However, to the best of our knowledge, no study has reported the microplastic occurrence in the lake ecosystem in Indonesia. Lake Singkarak, a big tectonic lake, has been considered one of the priority lakes to be restored. The lake receives a high influx of plastic waste from rivers and catchment runoff. Controlling the outflow through the hydropower dam and the sluice in the main lake outlet may prevent the microplastic’s outflux. The study’s objective was to determine the microplastic first occurrence and abundance in the lake’s surface water. Water samples were collected from three sites in the lake inlet area, one in the intake area of the hydropower dam and one in the outlet area, by performing four parallel trawls in each site using a modified plankton net. The most abundant microplastics in the lake’s surface water were 9 particles/m3 in the lake inlet area, which received a high plastic waste input from the river. The lowest abundance was 2 particles/m3 in the main lake outlet area. Foams and fragments, white and clear in color, size of 300 μm, were the dominant types of microplastics observed. Our preliminary study suggests that the lake could act as a sink of microplastics. Therefore, ceasing the input sources of plastic waste from the river should be prioritized to prevent further microplastic pollution of Lake Singkarak.

Evaluating Inflow Result from SWAT Model at Singkarak Lake Under Limited Data

Sustained lake functioning requires proper management in the catchment area and the water body. To address this, information on lake water balance is crucial because it is the basis for many scientific investigations of processes that occur in lake ecosystems. In many lakes, inflow from catchment areas is dominated by river flow. The problem is that inflow measurement data on rivers into the lake are difficult to obtain. Several models are used for inflow estimation, but validation will undoubtedly be complex because there is no observational data. The approach taken is to analyze the model results’ inflow accuracy through water balance analysis based on observational data on water level, climatology, and outflow. This approach will be implemented on Singkarak Lake, 109.08 km2, which is a tectonic lake located in West Sumatra. The method used to calculate inflow uses the SWAT hydrological model based on land use data in 2014 and Chirps rainfall in the 2010-2019 period. Water balance analysis is used to evaluate the inflow of the model results based on observational data on water level and outflow. The results show that the monthly inflow is too high, with an average excess of 6.21cms, which causes the average water level to be 0.52 meters higher.

Macroplastic abundance at Lake Singkarak riparian, West Sumatera

Macroplastic waste has been spotted around the shoreline and the waters of Lake Singarak, West Sumatra. Macroplastic waste has been the main source of microplastic pollution in the marine and freshwater environment. This study aimed to determine the types and abundance of macroplastic waste in the riparian area of Lake Singkarak. Macropalstic waste collection was carried out using a 0.25 m2 square transect with a radius of 10 m at six sampling locations around the lake. The collected macroplastic waste was then sorted by its type and calculated to determine the abundance of each type. The six collection points, the most abundant macroplastic waste was at a hotel area (Sumpur) with a waste weight of 3.07 kg/m2, while the shoreline area (Batu Baraguang) with less human activity was the location with the lowest waste abundance of 0.53 kg/m2. The dominating types of macroplastic waste at Sumpur Hotel were plastic film (33%) and hard plastic-fragment (19%). Not only at Sumpur Hotel, the plastic film type also became the most dominant type of macroplastic waste observed in all sampling locations, except at the main river inlet area (Sumani) where the most dominant type found was styrofoam. Overall, there were four types of macroplastic waste that dominated in the riparian of Lake Singkarak, namely plastic film, food bag packaging, hard plastic fragments, also bottle and cup packaging. A high abundance of macropalstic waste in the riparian area could pose a risk of microplastic pollution in Lake Singkarak.

Subsurface structure of Sumani segment in the Great Sumatran Fault inferred from magnetic and gravity modeling

The Great Sumatran Fault (GSF) 1900 km long active and segmented strike-slip faults. One of the segments is the Sumani segment in the province of West Sumatra that passes through a relatively densely populated area. Knowing the geometry of subsurface structures in this segment is one of the efforts to identify potential disasters in the future. To achieve this objective, ground magnetic measurements were carried out and the data were combined with Bouguer anomaly map. Magnetic susceptibility and density were also measured on hand samples collected during the survey so that their values could serve as initial parameters for modeling. The modeling and interpretation stages are carried out through joint forward modeling magnetics and gravity. The equivalent depth of the magnetic and gravity models built under the surface is 20 km. The magnetic and gravity modeling identify several intrusive bodies that do not reach the surface, including one beneath Lake Singkarak. Several slivers of Permian metamorphic rocks encased in the basement rocks were also identified. These unexposed intrusive bodies and slivers of encased metamorphic rocks are probably quite common in the GSF. The magnetic and gravity modeling with 2D modeling also infers an 18 km displacement in Lake Singkarak based on displacement of Quaternary colluvium volcanic deposits. Based on the presence of hot spring at the end of Sumani segment, the pull-apart pattern occurred in Lake Singkarak share similarities with that occur in another segment of GSF, namely Tarutung.

Estimation of Fish Production Potential with Benthos Biomass Approach in Sumani and Ombilin River of Singkarak Lake West Sumatra

The potential for fish production is very important as a necessary material for WPP PD in making policies. Estimation of fishery production potential is adjusted to aquatic ecosystem. The method used differs between running and stagnant water based on the shape of the water. Fishery resources in Indonesia, especially inland fisheries, still cannot be managed and utilized optimally and sustainably. The method used in estimating fishery stocks in the watershed is the Leger-Huet method. Research to estimate fish production potential using the benthic biomass approach using the Leger-Huet method was carried out in February, June, and October 2019 in the Sumani River and Ombilin River, Singkarak Lake. The research objective was to determine the estimated value of fish production potential through the benthic biomass approach in the Sumani River (Inlet) and Ombilin River (Outlet), Singkarak Lake. The calculation of benthic biomass and fish production potential was carried out at the Testing Laboratory of the Research Institute for Inland Fisheries and Extension in Palembang. This system is expected to be able to provide alternative solutions for decision-making and agencies to determine the potential for fish production in an area. The determination of the potential for fish production using the benthic biomass approach is highly dependent on the width of the river. The results showed that the types of benthos in the Sumani and Ombilin rivers were 5 classes and 17 families. The benthos found by the Ombilin River are more varied than those in the Sumani River, and the estimated fish production potential of the Ombilin River is greater than that of the Sumani River. The highest yield of benthic biomass was found in the Ombilin River (159.06 gr/m2) compared to the Sumani River (76.06 gr/m2). Meanwhile, the average potential fish production in the Batang Sumani River (573.8 (kg/ha) is higher than in the Ombilin River (244.74 kg/ha).

Kajian Alternatif Metode Kerja Perbaikan Trashrack (Saringan) Intake Malalo Unit PLTA Singkarak

The Singkarak Hydroelectric Power Plant with a capacity of 175MW is the backbone of the Central Sumatra Subsystem (SumBagTeng) in the Sumatran electricity interconnection system so that the reliability of the Singkarak hydropower operation must be maintained. However, after more than 12 years of operation the Singkarak Hydroelectric Power Plant suffered damage to the trash rack of the Malalo Intake caused by the September 30, 2009 earthquake that hit Padang-Pariaman where the filter segments and the filter girder beam fell to the bottom of the intake. This results in waste originating from Singkarak lake being free to enter the head race tunnel and then to the generator engine generator which can interfere with the operation of the Singkarak hydropower plant so it is necessary to repair the Malalo trashrack intake. This study aims to evaluate several alternative work methods for repairing the trash-rack intake of Malalo PLTA Singkarak to minimize disruption to the operation of PLTA Singkarak during repairs. Three alternative improvement methods were evaluated using the Zero-One technique and weighting. From the results of the evaluation, it was found that the underwater construction work method is the best alternative to repair among other methods. Furthermore, the details of the implementation plan for the underwater construction work method are presented as a reference for the implementation of the repair PLTA Singkarak trash rack.

Collective Action in Lake Management (CALM): an Indonesian stocktake

More than 500 lakes in Indonesia have been recognized as important parts of local economies and, at least in some cases, identity, but there is little literature on resource management and collective action. By reviewing literature and using a ‘serious game’, this paper aims to (1) review some of the currently used generic frameworks for understanding collective action in natural resource management, (2) recount some experiences in supporting collective action in Lake Singkarak, Sumatra and (3) describe early steps in using ‘serious games’ developed elsewhere to increase stakeholder understanding of how upstream land management affects lake quality and functions. Some important findings are that collective action is an important key to sustainable natural resources management and the lake as a complex social-ecological system also requires collective action of multi-stakeholders from upstream to downstream. We recommend the use of DPSIR and Javanese ‘gunungan’ frameworks together with ‘serious game’ to identify socio-ecological problems and build multi-stakeholder collective action. Based on our initial research experience in Lake Singkarak, this combination of methods has succeeded in finding various problems, especially different types of knowledge, ways of knowing, and learning styles from multi-stakeholders. These problems are then used as a basis for finding and forming a common understanding which is then transformed into collective action in lake management.

Integration of the latest Digital Terrain Model (DTM) with Synthetic Aperture Radar (SAR) Bathymetry

Topography and bathymetry integration is one of the essential things in providing height data. So far, the topography and bathymetry problems are the lack of height data availability, not up to date, and low vertical accuracy. The latest DTM is one of the topography data with up to date elevation with a spatial resolution of 5 m. Bathymetry extracted from SAR images. It is an alternative depth data for ocean bathymetry and inland water bathymetry. Topography and bathymetry integration is required to obtain comprehensive height data. This study aimed to integrate the latest DTM with SAR bathymetry. The method used in this integration was DEM integration. The method combined the latest DTM data with SAR bathymetry based on the correlation of the two data's standard deviation. The integration of the latest DTM with SAR bathymetry needs to consider differences in height reference fields. Two integration studies were conducted in this research-the latest DTM integration with ocean bathymetry for Rote Island. Then the integration of the latest DTM with inland water bathymetry in Lake Singkarak. The result of the integration is necessary to check the surface by generating longitudinal and cross-section profiles. Integrating the latest DTM and SAR bathymetry can be used for various mapping surveys on lands and waters.
