Terasering Mekar Erosion Control Model in Batur Lake Zone

Abstract

Erosion control in Lake Batur area is community-based directed to maintain lake balance. The aims of this research is; (1) to obtain a community-based erosion control model, (2) to analyze the role of communities in the application of land management models. (3) Analyzing other plant species in collaboration with the arrangement model . (4) Analyzing the impact of terraces blooming against sedimentation. This research is field experiments and surveys, and the sampling was conducted by purposive sampling with 64 samples. The socio-economic support data of the community was determined by 180 respondents by cluster sampling. Interviews and questionnaires were conducted through closed questions on a conventional scale. The characteristics of the lake were analyzed statistically and descriptively by using the SPSS tool. Land mapping was conducted by GPS method with GIS device. Prediction of erosion was by using USLE Model, while sedimentation was measured by the Stanford Sediment model. The analysis shows that the increase of settlement is averagely of 115,85%, plantation is 245,50% and the sedimentation level is 1,017,93 m3 / year. Conclusions and outcomes were in the form of community-based terracing model that collaborate with elephant grass and vetiveria plants.

“…This research is development research with the ADDIE development model, namely Analysis (preplanning), Design (designing concepts), Development (developing tools), Implementation (implementing products on learning), and Evaluation (measuring the achievement of product development) (Nada, 2015). The stages of ADDIE development can be seen in the following Figure 2.…”

Assessing lake shoreline change and prediction for 2030 by physical drivers: A Case Study from Lake Batur, Batur UNESCO Global Geopark, Bali

“…Sedimentation in water resources occurred due to soil erosion in their catchment area. Erosion, sedimentation, and siltation in the lake are influenced by the management of agricultural land around the lake; this does not consider the aspects of soil and water conservation (Nada et al, 2019). This sedimentation is potentially increasing water level of the lake and changing the shoreline.…”
