Abstract

Tanah adalah pondasi dasar penting yang melandasi berdirinya suatu fasilitas kehidupan makhluk hidup yang berusaha untuk menjalani hidup terutama manusia. Tanah mempunyai banyak beragam karakteristik dan jenis yang mempunyai manfaat dan tujuannya sendiri untuk kebutuhan makhluk hidup yang berbeda juga. Dalam hal ini manusia telah banyak mempelajari beragam sifat dan karakteristik tanah yang mereka wujudkan dalam bentuk pembelajaran atau penelitian. Manusia mengelompokkan tanah menjadi beberapa jenis dengan menggunakan metode yang telah disetujui oleh semua pihak manusia yaitu USCS dan AASHTO. Dalam jurnal ini selain membahas karakteristik tanah juga membahas mekannika tanah yang melibatkan berbagai macam komponen stabilitas berfungsi untuk jalan.

Abstract

River water quality has degradation due to anthropogenic activities in urban areas. It is requires an effective and sustainable monitoring approach. This study aims to evaluate the water quality of Sumo River, Surabaya, through biomonitoring method using macrozoobenthos indicators and physico-chemical parameters. Sampling was conducted in three segments (1, 2, and 3) by analyzing BOD, COD, pH, temperature, TDS, turbidity, and Shannon-Wiener diversity index (H'). Results denoted that BOD (13,4 – 33,23 mg/L) and COD (34,6 – 76,26 mg/L) values in all segments exceeded the class 3 quality standard, Appendix VI, PP No. 22 of 2021, with the highest pollution in segment 3. The parameters pH (7,6 – 7,76), temperature (29,5 – 29,6°C), and TDS (465 – 551 mg/L) still met the standard, but turbidity in segment 3 reached 16,39 NTU. Biological analysis revealed a decrease in macrozoobenthos diversity from segment 1 (H' = 1,0588) to segment 3 (H' = 0,5004), dominated by pollution-tolerant species such as Tubificidae. These findings reflect the severe ecological pressure due to the accumulation of domestic and industrial waste, especially in segment 3 with slow flow and poor waste management. This study recommends the implementation of an integrated sewage treatment system, increased community education, and periodic biomonitoring-based monitoring for the sustainable recovery of the Sumo River ecosystem, Surabaya City.
