“…The low abundance of microphyta as an autotrophic organism (the provider of chemical energy for the trophic organisms above) is thought to be related to the ecological conditions of the Pager river, where the water reacts with acid, where in this atmosphere the nutrients that are actually needed by the microphyta are entangled [8], [23]. Although the difference is quite small, the abundance of microphyta at station B (left side of the river) has something to do with household waste disposal (gray washwater) for community settlements in Pager Urban village on the left side of the road (before the bridge) especially when the water level decreases [24], [25].…”

Environmental damage due to natural resource extraction, especially in watershed areas, seems to be of increasing concern and so far, from the aspect of aquatic and water resources, plankton is commonly used as an indicator of environmental damage. This study explores the distribution of microphyta as a parameter of environmental damage. The research was conducted in Pager watershed, Central Kalimantan and sampled at 2 (two) stations, namely station A (for the right side of the river) and station B (for the left side of the river). The study was conducted 13 sampling times, which began in the period 25 May 2019 ending until 9 November 2019. Laboratory analysis to identify the type and number of microphyta was carried out at the Palangka Raya University Laboratory. The results showed that the number of microphyta taxa at station A (right side of the river) was 12-13 species, more than station B (left side of the river). The number of microphyta taxa at Station B is 8 - 9 species, it is suspected that there is an influence from the gray water settlements around the left side, especially when the water level drops. The distribution characteristics of microphyta in the Pager river are as follows: large number of taxa/species, low abundance and low diversity index. River/peat water environments are vulnerable to change, especially human interference. This research shows the potential use of microphyta as an indicator of environmental damage.

Land use is one of the macro parameters that affects water quality in a watershed. The Cimanuk watershed which is dominated by agricultural land use and settlements has encountered a decline in water quality. There are eight parameters including pH, TDS, TSS, Nitrate, Phosphate, Sulphate, BOD, and COD analyzed to evaluate water quality utilizing the Pollution Index (IP) method. This research has provided a clear understanding of the status of water quality in the Cimanuk watershed based on six monitoring points carried out at the start of the 2018 rainy season. Overall, the IP values obtained ranged from 2.05 to 5.96 with the lightly polluted category at points A, B, C, D, and E, while for point F it was in the moderately polluted category. The key parameters that have the most influence on water quality pollution are Nitrate, Phosphate, Sulphate from fertilization activities in agricultural land, while runoff from settlements contribute to increasing parameters of BOD and COD. These results can be beneficial for sustainable management of water and land resources in the Cimanuk watershed.

Abstract. The Kampar River estuary is well known for a tidal-bore phenomenon called system of Kampar River. Scoured materials, resulting from the hydraulic jump of the tidal bore, are carried into the middle of the river. These materials are then deposited when the velocity of the river decreases as a result of the collision of the tidal current sedimentation with respect to the river line and perform land-cover change analysis for the area around the Kampar River estuary for the years of 1990, 2007, 2010 and 2016. which uses an overlay technique to yield alternate information on the river line and land-cover changes in the form of time-series data. The largest erosion occurred during plantations (11.57 ha/year), building/settlement (48.11 ha/year) and scrubland (30.88 ha/year). The other types of land cover, such as bare land and sediment deposition, varied every single year. The changes to the river line are caused by land-cover changes, and the Bono waves that lead to erosion and sedimentation that is not stable in the middle of the river and downstream.Keywords: spatial analysis, land cover, Bono, Landsat imagery, Kampar River estuary.

Muara sungai Kampar terkenal dengan fenomena Tidal Bore yang disebut terhadap dinamika sistem muara di sungai Kampar. Material sedimen yang teraduk karena lompatan hidrolik dari tidal bore terbawa hingga ke bagian tengah sungai. Material tersebut terendapkan ketika kecepatan arus menurun sebagai akibat dari pertemuan dua arus yaitu arus dari laut dan aliran sungai. Tujuan dari penelitian ini adalah untuk mengetahui wilayah erosi dan sedimentasi dengan menggunakan pendekatan analisis perubahan garis sungai dan tutupan lahan disekitar muara sungai
