“…Waduk Titab memperoleh air dari empat sungai. Air sungai Saba diketahui tercemar ringan dengan pencemaran yang mendominasi dari kegiatan budidaya pertanian dan ternak, serta perkampungan dan pasar (Darmasusantini et al, 2015). Selain itu, parameter suhu yang biasanya tinggi diyakini berdampak pada peningkatan nilai pH air.…”

“…Tingginya kadar COD disebabkan oleh sampah rumah tangga yang mengkontaminasi aliran Sungai Saba. Adanya usaha dan atau industri kerajinan logam, wash car, laundry, bengkel dan peternakan unggas berimplikasi pada peningkatan kadar COD (Darmasusantini et al, 2015). Selanjutnya, penelitian Şener et al (2013), mengungkapkan kadar COD tinggi dalam air berimplikasi pada penurunan konsentrasi DO yang berdampak buruk pada keberadaan dan pemenuhan oksigen bagi hewan air.…”

Monitoring water sources is essential to ensure the quality and quantity, one of which is in the Titab Reservoir. The purpose of the study was to assess the water quality and amount of pollution in the Titab reservoir in terms of physical, chemical, and microbiological characteristics, as well as the NVC of Tawes (Barbonymus gonionotus) fish. There are five station points for water sampling and 10 test parameters related to water quality. Data analysis compares test results with second-class water quality standards (Bali Governor Regulation No. 16/2016), IP value (pollution index), and NVC with Furton's equation. The test results obtained that the water in the Titab reservoir has a temperature of 28.97oC, TSS (0.18 mg/L), pH (8.82), BOD (3.22 mg/L), COD (16.70 mg/L), DO (6.77 mg/L), Total Phosphate (0.12 mg/L), Nitrate (0.19 mg/L) and Fecal Coliform (960 MPN/100 mL), the IP value was 1.39, and the NVC was 1.65. Thus, the pH, BOD, and Fecal Coliform levels of the Titab reservoir water did not match the specified limits, although the other parameters satisfied the water quality norms. The Titab reservoir's water is classed as mildly contaminated with the NVC value of tawes fish, referring to the Titab reservoir's polluted water. Keywords: Tawes Fish, Titab Reservoir, Water pollution, Water quality.

The problem that occurs in Lake Sentani is that it has been contaminated by parameters of TSS, BOD, Pb, Cu, and DO respectively with valuesof 76 mg / L, 4.63 mg / L, 0.035 mg / L, 0.03 mg / L, and 5.72 mg / L because these parameters have exceeded the quality standard according to environmental regulations. This study aims to determine the assimilation capacity of TSS and PO4 parameters and analyze pollution control models in the Tlaga Ria sub-watershed. The research method used to determine the assimilation capacity is a linear regression equation and in analyzing the pollution control model the interpretative structural modeling method is used. The results showed that the TSS assimilation capacity value in Lake Sentani was -12,700 tons/month. The value of water quality in Lake Sentani is above the value of the assimilation capacity, this shows that Lake Sentani has been polluted by TSS parameters. Meanwhile, the value of PO4 parameter assimilation capacity is 44.36 tons/month and since 2016 Lake Sentani has been unable to conduct self purification. The key elements of the Sentani Lake pollution control constraints in the Tlaga Ria watershed are weak implementation of environmental regulations, differences in objectives among stakeholders, differences in objectives between administrative areas, weak support of business owners, conflict of interests, and weak enforcement of regulations.

“…However, these areas are increasingly vulnerable to threats from human activities that exploit them. Disposing of the household waste directly into aquatic systems can escalate the concentration of contaminants (Susanti 2015). The diminution of riparian vegetation is expected to affect ecological functions and riparian ecosystems' stability negatively (Singh et al 2021).…”

Abstract. Pramadaningtyas PS, Chandrasari N, Izdihar RS, Iqbal WM, Cahyaningsih AP, Setyawan AD. 2023. Analysis of riparian vegetation in the Siwaluh River, Karanganyar District, Central Java, Indonesia. Intl J Bonorowo Wetlands 13: 45-56. This research was conducted in the Siwaluh River Basin region, Karanganyar District, Central Java, Indonesia. Land conversion into residential areas has lowered infiltration capacity, particularly in the Siwaluh River riparian vegetation, in the form of reduced or even lost vegetation that should serve as a water catchment area and habitat for riparian plants. The research was done to analyze riparian vegetation in the Siwaluh River to collect data for the conservation of the riparian zone, which plays a vital role in ecology and the ecosystem. Calculating the maximum IVI value and the existence of plant species from the diversity of riparian vegetation could determine the dominant vegetation type in a given area. The quadratic plot method employed was used; square plots of 20mx20m for trees, 10mx10m for poles, 5mx5m for saplings, and 2mx2m for seedlings were established at each sampling location. After that, the vegetation investigation comprised density, dominance, frequency, Shannon-Wiener diversity index, and IVI. The survey identified 209 plant species; Kigelia africana dominated the highest IVI value in tree habitus. Practically, in each upstream, middle, and downstream location, Bambusa sp. dominated the highest IVI in the pole habitus, Manihot esculenta controlled the highest IVI in the sapling habitus, and Ageratum conyzoides dominated the seedling habitus. Variations in the diversity index (H') of tree, pole, sapling, and seedling habitus result from reduced or even disappearing vegetation due to land changes. Therefore, it changes the distribution pattern of riparian vegetation.
