Abstract

Kolam retensi Ario kemuning adalah salah satu dari beberapa kolam retensi yang ada di kota Palembang yang terletak di Jl Swadaya Lorong Perikanan IV Kelurahan Talang Aman dan berjarak + 6 km dari pusat kota. Dengan jarak tempuh +15 menit dengan kendaraan mobil atau motor dan dengan kondisi jalan aspal yang baik. Kolam retensi ini berada dalam satu sistem dengan sistem saluran bendung. Kolam Retensi Ario kemuning berada diatas tanah dengan luas + 14,977m2. Kondisi kolam retensi Ario kemuning termasuk dalam kondisi daratan rendah dan daerah yang berawa-rawa, dengan topografi relatif datar dan merupakaan daratan rendah. Pada setiap hujan deras, genangan air sering terjadi di daerah saluran masuk kolam retensi Ario Kemuning, dimana genangan air yang terjadi menyebabkan rusaknya jalan, dan juga terhambatnya pengguna jalan kaki.Berdasarkan hasil penelitian ini kolam retensi Ario kemuning melalui dimensi saluran inlet dengan nilai h = 3 meter, tidak lagi dapat menahan Q Inflow = 5,060 m3/det. Untuk dapat menahan debit air yang masuk saluran inlet kolam retensi tersebut mesti diperbaiki nilai h saluran tersebut begitu juga dengan saluran outletnya mesti dibersihkan sedimen dan penumpukan sampah agar air yang mengalir disaluran tersebut lancar. Kolam retensi Ario Kemuning tidak dapat lagi menampung, air apabila hujan selama lebih dari 41,4 menit dikarenakan kurangnya perawatan dari instansi terkait, sehingga menyebabkan tergangunya sistem kerja dari kolam retensi tersebut. Saluran inlet dan saluran outlet tidak dapat menampung air masuk kedalam kolam dan keluar kolam dikarenakan adanya sedimen dan penumpukan sampah sehinga menganggu aliran air.

Abstract

In this study the author take Fly Ash and Powder Glass as an added ingredient in the concrete mix. This research intend to know the effect of Fly Ash and Powder Glass on K-300 concrete compressive strenght.This study uses cube-shaped specimens with the siza of 15 x 15 x 15. The total of test specimens in this study as much as 45 sample, each 9 seal of test specimens in 5 condition that is normal, concrete + fly ash 5% + glass powder 18%, concrete + fly ash 5% + glass powder 21%, concrete + fly ash 5% + glass powder 24%, concrete + fly ash 5% + glass powder 27%.After concrete compressive strenght test, the concrete strength og the concrete at age 3, 7 and 28 days with normal condition at 3 days age aqual to 139.26 Kg/Cm2, at age 7 day equal to 202.17 Kg/Cm2 and age 28 day of 307.01 Kg/Cm2. And the value of compressive strength of concrete characteristic with the use of Fly Ash 5% + glass powder 18% has the highest value of concrete compressive strength that is at 3 days age of 151.13 Kg/Cm2, 7 day age equal to 21175 Kg/Cm2 and age 28 is 312.81 Kg/Cm2 . These result exceed the copressive strength values of normal concrete characteristic and show that fly ash and glass powder can increase the compressive of the concrete.

Abstract

In the development of concrete technology (Concrete Technology) today which is increasingly unceasingly, along with the development of the era hence the quality of concrete selection as the main raw material of building construction is very important. This research writer take silica fume and glenium sky as added concrete mixture to know the influence of the addition of silica fume and glenium sky to the compressive strength of concrete. The research is divided into three stages : material testing, test object making and test object. This research uses cube-shaped specimen with size 15x15x15 cm, with 5 variations, they are normal concrete, silica fume 5%, silica fume 5% + glenium sky 2%, silica fume 5% + glenium sky 4%, and silica fume 5% + glenium sky 6%, which every variations has 3 test specimens with 3 days, 7 days, and 28 days. From laboratorium testing, the characteristics of compressive strength of concrete at age 28 days of normal concrete is 407,2 Kg/Cm2, normal concrete with silica fume 5% is 418,5 Kg/Cm2, normal concrete with silica fume 5% + glenium sky 2% is 435,9 Kg/Cm2, normal concrete with silica fume 5% + glenium sky 4% is 451,9 Kg/Cm2, normal concrete with silica fume 5% + glenium sky 6% is 484,1 Kg/Cm2.

Abstract

Technological advances provide opportunities for construction workers to use heavy equipment as a substitute for manual equipment. Heavy equipment can be a solution to increase the efficiency and effectiveness of work implementation, which can be seen in the cost calculation or unit price.It can be seen that alternative 3 uses 2 units of Kobelco PC-200 excavators, 4 units of 5 m3 dump trucks, these alternatives have the smallest time difference to the original conditions in the field. Therefore, it is very time efficient and fast to process and costs slightly increases and results in fast and efficient workmanship. It can be seen for the difference in costs of - 28,905,973 (- 26%) and the difference in total working time of -25 hours (- 40%). Referring to the description of the calculation of the comparison between the original conditions in the field with alternative calculations, if a minus (-) result is obtained then the work is faster. So it can be recommended to use alternative 3 to carry out soil removal work in the Wastewater Treatment Plant project. Palembang, South Sumatra.

Abstract

To meet the needs of clean water in the Sungki Simpang Market Area, the distribution of clean water plays an important role and is very much needed by local residents. There are still many obstacles that result in a lack of water supply, so that people rely heavily on PDAM Tirta Musi Booster Kertapati to meet their clean water needs.In this study, the authors analyzed the energy loss factors in the distribution network of clean water pipes from Booster Kertapati to Sungki Simpang Market Area, factors that affect energy loss in the pipe distribution network include flow rate, flow velocity, pipe bend angle, pipe friction, and change in pipe cross- section.The results of the calculation show that the largest total energy loss is in the I-J pipe segment of 71.47446 m, the Ø0,1016 m or Ø4 inch pipe with a speed of 4.35800 m/s and the smallest total energy loss is in the C'-C pipe section of 0.10979 m , the Ø0,1016 m or Ø4 inch pipe at 1.38004 m/s. So it can be concluded that not only the number of turns, changes in the cross-section and length of the pipe that affect the energy loss factor, the flow velocity is also a factor in the energy loss.Keywords: Energy Loss Factor, Analysis Result.
