“…The results of the analysis showed that the estimated N exports entering Lake Rawapening totaled 847,899.59 kg./year (37.5%), and the estimated P exports totaled 153,145.44 kg./year (35.7%) (Nugroho, 2022b). These high nutrient export levels contributed significantly to the eutrophication process in Lake Rawapening, which was classified as anthropogenic eutrophication.…”

“…The nutrient export at the watershed or sub-watershed level was calculated by aggregating the N and P loads reaching each pixel's stream/lake body. Details of the analysis of nutrient export from Lake Rawapening can be found in Nugroho (2022b). Details of the biophysical table, such as root depth and coefficient of plant (Kc) can be found in Nugroho (2017).…”

“…This research collects data from literature and institutional documents (Nugroho, 2022b). The data presented in Table 1 is used in modeling nutrient export using the Nutrient Retention sub-model and simulating the effects of lake and stream buffer zone widths on nutrient export to Lake Rawapening.…”

“…However, all studies focused on the magnitude of nutrient export and spatial distribution of eutrophication in Lake Rawapening. Nugroho (2022b) estimated nutrient export's magnitude and spatial distribution using the InVEST (Integrated Valuation of Environmental Services and Tradeoffs) software suite. Piranti (2019) observed the magnitude of nutrient export during the rainy and dry seasons.…”

Lake ecosystems in Indonesia face serious environmental problems. One of those problems is eutrophication caused by excessive plant nutrients, particularly nitrogen (N) and phosphorus (P). Water quality degradation and biodiversity loss are the effects of eutrophication. The government of Indonesia (GoI) has issued a regulation on determining lake and stream buffer zones, but it has not been fully implemented in the field. Additionally, the data related to the effects of each buffer zone width is not available. This study aims to begin to fill this gap. It simulates the effect of lake and stream buffer zone widths on nutrient export to Rawapening Lake. The Nutrient Retention sub-model, which is part of InVEST (Integrated Valuation of Environmental Services and Tradeoffs) software, has been used for this research to analyse information from several data sources, including a Digital Elevation Model (DEM) and measurements of soil depth, annual rainfall, land cover/use, watershed/sub-watershed boundaries, and biophysical conditions. Several studies of eutrophication in Rawapening Lake have measured the magnitude of eutrophication but have not discussed the effects of buffer zone widths. Therefore, this study accommodates the updated data on how much effect of buffer zone widths on the reduction of nutrient export. Five scenarios of buffer zone width are considered: 30 m., 90 m., and 150 m, where the lake buffer zone widths and the stream buffer zone width are 30 m. The results indicated that the maximum nutrient export reduction of lake buffer zones was only 2.63% (for N) and 3.56% (for P). On the other hand, the 30 m stream buffer zone width reduced the nutrient export to Rawapening Lake by up to 43.05% for N and by 44.90% for P. A 30 m combined lake and stream buffer zone width slightly increases the nutrient export reduction effectiveness, i.e., 0.41% and 0.56% for N and P, respectively.

Indonesia adalah negara yang memiliki jumlah danau yang banyak. Diantara jumlah danau tersebut, ada beberapa danau yang memiliki kerusakan lingkungan yang parah sehingga perlu direvitalisasi. Danau Rawa Pening menjadi salah satu danau prioritas penanganan oleh pemerintah. Revitalisasi danau adalah kegiatan untuk mengembalikan fungsi alami danau sebagai tampungan air melalui beberapa kegiatan yang bersifat struktural maupun non-struktural. Dalam perumusan kebijakan dan strategi revitalisasi danau Rawa Pening dibutuhkan data dan informasi supaya hasilnya tepat sasaran. Hal tersebut adalah lingkungan yang mana terdiri dari komponen abiotik, biotik dan budaya. Pemahaman kondisi lingkungan secara komprehensif dirasa akan mempermudah dalam penentuan strategi dan kebijakan pengelolaan Danau Rawa Pening. Setelah memahami kondisi lingkungan, kita bisa mengdentifikasi bentuk pengelolaan Danau Rawa Pening. Bentuk pengelolaan Danau Rawa Pening sebaiknya adalah dengan tindakan preventif, bukan tindakan seperti rehabilitasi. Bentuk pengelolaan bisa difokuskan pada pengendalian erosi-sedimentasi dan eutrofikasi yang tak hanya disekitar Danau Rawa Pening tetapi juga bagian hulu sub-DAS yang berada di DTA Rawa Pening.
