“…Note that the reservoir lifetime calculation in this paper assumes no change in the watershed's land use. Land use change will alter reservoir sedimentation [43][44]. Examples of land use change are urban sprawling and conversion from vegetation into a settlement or industrial area [45][46].…”

Sedimentation can severely limit the service lifetime and functionality of reservoirs. The application of the Universal Soil Loss Equation (USLE) requires validation of its accuracy and applicability despite its prevalence. This study compares reservoir lifetime predictions for the Leuwikeris Reservoir on the Citanduy River using the USLE model and the suspended load records from the field measurement. The comparison shows a reasonable similarity between the theoretical calculation and the factual observations in determining the amount of watershed soil loss and the reservoir lifetime. Although the validation is successful, USLE and the measurement technique have their specific limitations. In particular, the inability of USLE to consider both gully erosion together with sedimentation and the inability of the measurement technique in detecting bed load. Despite the limitations, these results are in line with previous studies which stated that the USLE model is generally feasible in estimating the quantity of reservoir-bound sediment.

“…Problem permasalahan tersebut di duga karena tingkat laju pertumbuhan eceng gondok yang masif yang dapat meningkatkan tingkat laju sedimentasi terjadi. Penelitian lain oleh Sanjoto et al, (2020) memaparkan bahwa tingkat tingginya sedimentasi di Danau Rawa Penin disebabkan oleh perubahan penggunaan lahan pada daerah hulu Sub DAS Rawa Pening.…”

Danau Rawa Pening menjadi sistem penyimpanan air yang penting bagi masyarakat Kabupaten Semarang. Danau Rawa Pening memiliki permasalahan terhadap pendangkalan yang disebabkan salah satunya karena faktor eutrofikasi oleh tanaman eceng gondok. Pendangkalan danau berdampak buruk terhadap kapasitas penyimpanan air, sehingga dapat berpotensi mengalami luapan pada saat musim hujan. Luapan tersebut berpotensi menyebabkan kerugian pada pemilik lahan, dimana mereka tidak dapat menggunakan lahannya dikarenakan tergenang. Peneliti tertarik melalukan penelitian terkait analisis lahan berpotensi tergenang banjir menggunakan komputasi spasial MNDWI dengan bantuan citra Sentinel 2. Hasil penelitian ini menunjukkan luasan wilayah terdampak dan berpotensi tergenang pada saat banjir mencapai luasan hingga 645 Ha dengan hasil uji akurasi mencapai 87%.

“…Development activities also influence sedimentation in Rawapening catchment area. Research conducted by Sanjoto et al [3] shows that the development of built-up land cover in the Rawapening Water Catchment Area tends to increase. In 2000 the area of land was built 5,202 ha, then in 2009, it was 6,722 ha, and in 2019 it was 8,053.64 ha.…”

Rawapening is a natural lake located in Semarang Regency, Central Java. Currently, Rawapening is encountering some environmental problems such as sedimentation, and massive growth of Eceng Gondok (Eichhornia crassipes), conflict of interest in utilizing Rawapening and illegal buildings around Rawapening. On the other hand, the Rawapening community is very dependent on the existence of the lake in fisheries, agriculture, Eceng Gondok handicrafts, organic fertilizer production, and tourist attraction. For this reason, communities around Rawapening are expected to take part in maintaining the existence of Rawapening. Increasing ecological literacy associated with the Rawapening area is essential. Ecological literacy is an activity to understand the importance of preserving the environment supported by the environmental awareness. This article aims to determine the level of ecological literacy of the Rawapening suburbs in Asinan Village, Semarang Regency. The number of samples are 94 families proportionately spread in the hamlets of Krajan, Baan, Sumurup, and Mangkelang. The variables studied included knowledge of the Rawapening ecosystem, attitudes of sensitivity to environmental changes in Rawapening, and community behavior in saving Rawapening with environmentally friendly Behavior. The assessment was carried out using the 30 items multiple-choice test item through a test instrument. The results showed that the Asinan Village community's ecological literacy is mostly in the Good category. The details are from 94 respondents; there is 9.60% in the very high category, 55.30% in the high category, 34.1% in the medium category, and 1.0% in the low category. The details of sub-variables show that the average level of community knowledge related to ecosystem rewapening is high (3,9). The average Attitude of sensitivity to environmental changes in Rawapening is high (3,8), then the average Behavior of the community in terms of saving Rawapening is included medium category (3,1). From the results of the study, it was concluded that the ecological literacy level of the Asinan Village Community is in the high category; however, in terms of saving Rawapening with environmentally friendly Behavior, it was included in the Medium category. Therefore, it is necessary to carry out routine lake cleansing activities by involving the community to foster environmental care behavior in Rawapening.
