River is the place and the Container and also water drainage networks ranging from the spring to the estuary with restricted right and left and also up streaming along the lines sempada. One of the main river in South Sumatra is enim river. Recorded on 23 January 2016 floods occurred in the estuary enim that flooded the area around suangai enim. The purpose of this study was to determine the fl…
Rainfall simulator is a device used to create artificial rain to support variations of rainfall intensity and duration of rainfall variations automatically. Variation of pressure used was 2.5 psi, 3 psi, 3.5 psi, 4 psi, 4.5 psi, 5 psi, 5.5 psi, 6 psi, and 6.5 psi. Parameters used to study about the performance of rainfall simulator are rainfall intensity, the diameter of the raindrops, rain mas…
The Sekanak Lambidaro area was previously occupied by residential areas. The river area was filled with piles of garbage which flooded and then the settlements around it were irregular so that the environment looked dirty. So the Palembang City Government has carried out Revitalization as one of the flood management policies to repair the damage that exists in the area. The revitalization carri…
Pemahaman yang komprehensif mengenai curah hujan dan distribusinya baik dalam ruang dan waktu merupakan salah satu hal yang penting untuk keperluan perencanaan dalam berbagai bangunan rekayasa. Informasi mengenai distribusi curah hujan merupakan hal yang penting dalam berbagai keperluan, seperti rancangan jaringan curah hujan, peramalan hidrologi dan pemodelan daerah aliran sungai. Beberapa tah…

Penelitian ini dilaksanakan di Stasiun Climatologi Lab Hidrolika FT Universitas Sriwijaya. Data laju evaporasi metode pengukuran nenggunakan alat pan evaporasi, sedangkan data laju evaporasi metode empiris di lapangan nenggunakan alat windrunmeter, c…
Hujan merupakan fenomena alam yang sangat penting keberadaannya baik bagi pertanian maupun kehidupan kita. Dalam jumlah yang cukup dan terkendali, hujan merupakan Rahmat Tuhan yang tidak berhingga manfaatnya. Sebaliknya hujan akan membawa bencana jika jumlah dan sebarannya tidak terkendali. Di sisi lain, hujan merupakan fenomena alam yang sulit dimodifikasi atau dikendalikan. Mengenal dan memfo…
Plaque is a thin film on the surface of a tooth containing a variety of microorganisms. At cm early stage, plaque containing only microorganisms gram-positive facultative then will happen growth and maturalion of the plaque, so microorganisms turned into gram-negative facultative, gram-negative anaerobic and spirocheta. These microorganism will disturb the balance of the oral cavity its cause t…
Sungai Ogan merupakan salah satu sungai yang berada di Provinsi Sumatra Selatan. Sungai Ogan pada daerah penelitian dikontrol oleh Formasi Gumai (Tmg), Formasi Air Benakat (Tma), Formasi Muaraenim (Tmpm) dan Satuan Gunungapi Muda (Qhv) serta terdapat pada dataran rendah dengan panjang sungai 9 kilometer. Analisis morfometri dilakukan menggunakan aplikasi pendukung seperti Sistem Informasi Geogr…
Sub-DAS Sei Serelo secara administratif berada di Kabupaten Lahat, Sumatera Selatan dengan luas wilayah penelitian sebesar 11 x 11 km. Perubahan meander sungai terjadi disebabkan oleh beberapa faktor seperti proses sedimentasi berupa proses erosi dan pengendapan yang prosesnya berhubungan dengan karakteristik DAS itu sendiri. Terjadinya perubahan geometri meander pada Sungai Sei Serelo yang dii…
An experimental laboratory was conducted to treat produced water by kapok fiber adsorbent, activated using sodium hydroxide (NaOH) 5% wt. and hot water at 100 oC followed by ultrafiltration membrane to reduce total dissolved solids (TDS), barium, and phenol concentration. The research variables were operating times of 30, 60, and 90 min, and the flow rate of produced water samples was 5 L/min, …
This monograph presents, for the first time, a unified and comprehensive introduction to some of the basic transport properties of porous media, such as electrical and hydraulic conductivity, air permeability and diffusion. The approach is based on critical path analysis and the scaling of transport properties, which are individually described as functions of saturation. At the same time, the b…
A multidisciplinary study of Bera Lake in Malaysia is presented here, focusing on natural resources throughout the lake’s catchment area and assessing environmental impact. This applied limnology study examines issues relating to land development including soil erosion and nutrient loss in the catchment area, severe pollution of water, sediment resources in open waters and wetlands, and reduc…
The book provides a comprehensive overview of the hydrology of the Nile River, especially the ecohydrological degradation and challenges the basin is facing, the impact of climate change on water availability and the transboundary water management issues. The book includes analysis and approaches that will help provide different insights into the hydrology of this complex basin, which covers 11…
The inflluence of addition alum and filtration processes on water quality in water treatment Systems in the Desa Sumber Rejo has been researched. Quality parameters measured were pH, conductivity and TDS (total dissolved substance). The variables of this study was the addition of alum concentration (40 ppm, 80 ppm, 120 ppm, 160 ppm, 200 ppm) and variations in measurements every 5, 10, 15, 20, 2…
Banyuasin estuary is an area of estuaries that have an important role in terms of economy and ecology, where the river empties into large, and small river estuaries. Human activities such as industry, transport, deforestation and land clearing increasing of TSS and TDS in the estuary. This activity led to increased soil erosion along the river so that the impact on suspended solids and dissolve…
Groundwater availability of evaluation research has been carried out in Pematang Abab Lematang Ilir (PALI) and surrounding areas, which are included in the Lematang watershed in South Sumatra Province. In determining the impact of climate change on groundwater utilization at the research site, the method used is by using climate risk analysis, hazard analysis, vulnerability analysis, risk analy…
