Abstract

Biological assessment is an option in determining river quality, in this case related to river health. The biological assessment indicators used aquatic macroinvertebrates with research sites in the Pusur River which are located in Boyolali and Klaten Regencies, Central Java Province, Indonesia. The use of macroinvetebrata as an indicator because they are very sensitive to changes in water quality, one of which is the EPT group (Ephemeroptera, Plecoptera, and Trichoptera). Sources of river pollution will affect the existence of EPT and there are macroinvertebrates that are adaptive to contamination. This study was conducted at three monitoring stations located in the Pusur River, namely in the upstream, middle and downstream sections where each station had 6 repetitions in sampling followed by calculating the macroinvertebrate assessment index value. The results of the study show that the upstream station has an index value of 2.11 which means it is moderately polluted, the middle station has an index value of 2.40 which means it is moderately polluted and the downstream station has a value of 2.35 which means it is moderately polluted. From these results it is indicated that contamination into the river has started from the upstream area where the contamination originates from the disposal of unprocessed cow manure into river bodies, while in the middle and downstream areas the contamination that occurs is caused by dumping garbage, household waste and the use of pesticides and chemical fertilizers in agricultural ecosystem.

Abstract

Land vulnerability is a condition where a land is sensitive to environmental changes or human pressure. This certainly affects the productivity, quality, and sustainability of the land to recover from the impacts that may occur due to land changes. This problem certainly has a direct or indirect effect on the socio-economic life of the community. The purpose of this study is to map and recommend directions for Land Rehabilitation and Soil Conservation (RLKT) in Tamansari District, which in its development is in the Klaten Regency area, Subdas Pusur DS. The analysis method uses overlay of erosion land vulnerability, flood vulnerability, land cover, and land use capability. The results of the study indicate that the area of vulnerable land that needs to be RLKT is 4,375.7 ha covering 10 villages. The largest village that needs to be RLKT is Jemowo Village (668.9 ha) and Mriyan Village (644.7 ha). Land Rehabilitation and Soil Conservation Directions in the form of Reforestation with vegetation, cover crops, compost, reservoirs, rorak, terrace reinforcement, ridges, SPA, infiltration wells. The RLKT Direction is expected to be able to control land vulnerability to erosion, land vulnerability to flooding and water management so that it is expected to be able to improve the welfare of the community in the Tamansari District area.
