“…The bathymetric measurement data is presented in Table 7 and Figure 3B, then the cross section of the bathymetry map is shown in Figure 3C. The volume of the Tambakboyo Retention Basin is at an elevation of +147 so that in 2019 the reservoir has a remaining dead reservoir of 300,285.53 m 3 , of which the original design was 427,349.02 m 3 . By reducing the volume in 2019 with the initial design volume where the reservoir was completed in 2007, the volume of sediment that was accommodated in the reservoir for 12 years was obtained, namely 127,063.49 m 3 .…”

The Tambakboyo Dam has been operated for more than 10 years, resulting in increased sedimentation and reduced storage capacity from 400,000 m3 to 300,285 m3. Therefore, to support the optimization of water availability, the age of the reservoir needs to be known. This research analyzes the volume of sediment in the Tambakboyo Reservoir to determine the effective age of the reservoir by estimating the rate of erosion that occurs. The USLE method is used to determine the rate of erosion that occurs in the Tambakboyo Dam catchment area and bathymetry measurements are used to determine the volume of reservoir sediment directly. Using the USLE method, the DTA erosion rate was 13,864 tonnes/ha/year, while direct echo sounding measurements were 11,254 tonnes/ha/year. The remaining age of the reservoir based on the USLE method is 23.02 years, while direct measurements reach 28.359 years. So it can be concluded that the erosion rate in the Tambakboyo watershed is included in the very light erosion category, however the SDR results comparing sediment entering the reservoir with sediment calculated using the USLE method show that sediment control is still not effective.

“…Sermo Reservoir is an artificial multipurpose lake to support agricultural development, clean water distribution through the population in Kulon Progo, as a tourist attraction, and sometimes for fisheries activities (Sudarmadji & Widyastuti, 2014;Rahayu et al, 2016). Tambakboyo Retention Basin is an artificial water ecosystem constructed by the Yogyakarta Government to provide water reserves, groundwater catchment, and irrigation for Bantul District in Yogyakarta (Purwanto et al, 2017;Sriyono et al, 2019).…”

The Australian red claw freshwater crayfish, Cherax quadricarinatus is one of the most widely distributed and cultivated freshwater crayfish due to its high tolerance towards various environmental conditions. Native to North Australia and South Papua New Guinea, this crayfish was found in Tambakboyo Retention Basin in 2016 and Sermo Reservoir in 2019. This research was aimed to identify the morphological and molecular characters of C. quadricarinatus collected from Sermo Reservoir and Tambakboyo Retention Basin, Yogyakarta. The genetic information of the samples was compared to Australian red claw freshwater crayfish currently available. The methodology used for this research are morphological, morphometrical, meristic identification, and molecular identification using the PCR method. The primer used to be 1471 primers as the forward primer and 1472 primers as the reverse primer. In conclusion, all six specimens obtained were identified to be C. quadricarinatus. Morphological analysis using UPGMA showed that all specimens were formed one big cluster and has the highest similarity index (1.00). Molecular analysis using BLAST showed that specimen from Sermo Reservoir was 98.96% identical to C. quadricarinatus and specimen from Tambakboyo Retention Basin was 100% identical to C. quadricarinatus. Thus concluding that based on their morphological and molecular character, all samples of this study were C. quadricarinatus. This finding also contributes to the distribution information of C. quadricarinatus in Daerah Istimewa Yogyakarta
