Pilar is a structure under the bridge. The presence of pillars in river flow cause changes in river flow patterns. These changes include the formation of down flow (downward flow) and Horseshoe vortex (horseshoe vortex) around the pillar. Changes in flow pattern will result in local scour around the pillar. Local scour is going on around the pillar causes the river bottom around the pillar so that the water flow transported formed scour hole. Scour hole is formed can destabilize the pillar. Stability is very important pillar in the forwarding function of vehicle load to the foundation. This study aims to determine the maximum scour depth value of each form the pillars for any changes debit.Penelitian is done on a permanent uniform flow conditions (steady uniform flow) with three variations of flow rates that occur within the capacity of the appliance Multy-purpose teaching flume

Sandtrap channels are usually found at rivers intake for irrigation purposes. These channel were made to settle sands and prevent them from entering the irrigation channel. As result, the water that enter the irrigation channel will be relatively clean (with small concentration). This objective of this research applying finite different method to solve water flow differential equation as the basis computer`s software construction using Borland Delphi 5 language for sand trap, testing model`s ability against field measurement result, also applying efficiency point and sediment simulation of sandtraps.The analysis of discharge data, flow velocity, water depth, and field measurement result data as basis for total load calculation using Engelund Hansen, Leo Van Rijn, and Enstein Brown formulation approach. The result is using as an input data for sandtrap`s one dimensional empirical model formulation , which was developed by Eysink Vermaas (1983).

Pemukiman atau rumah tinggal dan perumahan merupakan salah satu kebutuhan dasarmanusia. Pemenuhan kebutuhan akan rumah tinggal yang sudah dilakukan belum juga dapatmenjangkau sebagian masyarakat, khususnya yang berlokasi di daerah-daerah. Walaupunmempunyai sumber material, tetapi masih belum dimanfaatkan secara optimal oleh masyarakatuntuk bahan bangunan, terutama bahan yang dibutuhkan untuk pembuatan beton. Sebagian besarbahan pembuat beton adalah bahan lokal (kecuali semen portland atau bahan tambah kimia).Selama ini baru sebatas pemanfaatan batu gamping (klastik siliklastik) untuk fondasi. Selain itudianggap sudah dapat menggantikan fungsi dari batu kali sebelumnya. Penelitian ini bertujuanuntuk mengetahui perbandingan kuat tekan beton dengan agregat pecahan batu gamping (klastiksiliklastik) dan beton dengan agregat batu alam krakal (andesit) pada umur 28 hari, mengetahuipengaruh variasi faktor air semen (fas) terhadap kelecekan beton segar dan kuat tekan beton padasetiap variasinya.

Until this this day the proper water consumption supply problem at the Pasir Pengaraian University campus still continues. The need for clean water is one of the contributing factors that can not be ignored for the smoothness activity of the campus environment. By not proper the water, directly impacting to activities support on campus will be distrubed. For the treatment of raw water to water consumption required inexpensive technology for water treatment, the installation of Slow Sand Filter (SSF) Up Flow is an alternative that can be used.From the research results can be determined a maximum daily requirement per day is 17.03 m³ / h, discharge of raw water in the pool is 76.65 m³ / h, the surface area of pool water sources is 191, 63 m², SSF tub surface area is 63.88 m² and budget plan is needed to create a pool of water sources and the SSF is Rp. 87.926.300
