Abstract

Waduk Lahor terletak pada desa Karangkates, Kecamatan Sumberpucung, Kabupaten Malang, Provinsi Jawa Timur. Waduk Lahor mulai beroperasi sejak tahun 1977 dengan usia rencana selama 50 tahun sehingga diharapkan dapat beroperasi hingga tahun 2027, masalah utama yang dihadapi dalam pengelolaan waduk adalah bagaimana menjaga agar umur layanan waduk dapat sesuai dengan yang direncanakan dikarenakan adanya sedimen yang mengendap pada dasar waduk dan seiring waktu akan semakin mengurangi tampungan efektif waduk., dan pada tahun 2015 tampungan mati Waduk Lahor menyisakan kapasitas 2.517.357,31 m3. Dari hasil studi didapatkan adanya keterkaitan antara debit sedimen (Qs) dengan debit inflow waduk (Qw) menggunakan model Regresi Berpangkat dengan fungsi Qs = 1,623.Qs0,72, pada pengujian  model didapatkan bahwa model stokastik Thomas-Fiering lebih representatif untuk pembangkitan data sintetik daripada model Rantai Markov dikarenakan memiliki simpangan lebih kecik dengan nilai RMSE 4,19 m3/detik dan nilai MAE 2,92 m3/detik. Dari hasil bangkitan data sintetik sepanjang usia rencana dan persamaan regresi berpangkat didapatkan volume sedimen tahun 2015 – 2027 dengan nilai trap efisiensi 88% sejumlah 1.822.200,05 m3, sehingga pada tahun 2027 diprediksi tampungan mati hanya menyisakan kapasitas 695.159,26 m3 dan dapat disimpulkan bahwa Waduk Lahor dapat beroperasi hingga usia rencana

Abstract

Setting the left turn movement at the intersection of four or three signalized intersections, and the straight movements at three signalized intersections. In any where, there are not provide significant for signalized intersection performance. Changes related legislation does not necessarily contribute positively to the traffic operation. Determination of the application of left turn on red  (LTOR) or straight on red (STOR) at an intersection must be preceded by a study, so that the positive affect or negative affect that happened can be known early. The background of this study was motivated the existing conditions arrangement, turn left movements (for intersection of four or three signalized intersections) and straight movements (for three signalized intersections) at some intersection in Malang Raya. In addition, this study was conducted in order to know the effect of setting the movement of vehicles turning left or straight at the intersection. The expected benefits of this study is, that every movement settings, turn left at the intersection of four or three signalized intersections, and also straight movements at three signalized intersections have to go through the review process. Conclusion, shows that the movement of vehicles turning left directly on the intersection of four or three signalized intersections, and the movement of vehicles at the intersection of three straight directly affect the performance of signalized intersections.Key words: signalized intersection, turn left movement, straight movement, the performance of a signalized intersection.

Abstract

Concrete is one of the construction materials of combination between cement, fine aggregate, coarse aggregate, and water mixed into one solid mass. The work of concrete making can be added a mineral additive as well as chemical additive (admixture) for the interest in construction work. In some cases construction work is desirable for concrete to produce optimum strength during the early age of the concrete so that the timing of concreting work can be shortened. The strength of concrete at the early age can be increased with added mineral (additive) and chemical (admixture) materials. This research made a mixture of concrete with 7 variations of mixture with total specimen 54 sample of cylindrical size with diameter 15 cm and height 30 cm. Tests conducted in the form of testing workability and compressive strength of concrete at the age of 3 days, 7 days and 28 days. Through this study obtained the right composition to make concrete with a high early age of compressive strength.

Achmad Yani Km. 5,5 Komplek Stadion Lambung Mangkurat, Banjarmasin 70249 AbstractThe river is a natural groove surface of the earth to drain the water and sediment, besides of course the interaction between discharge, sediment load and other factors such as human activity along the river gives the characteristics of the formation of different rivers. Each mining (including coal mining) must produce mine water or gas / air. Specifically for mine water, the largest portion comes from land clearing activities and waste material (waste) are easily eroded thus affecting water quality standards runoff coming out of the mining area and heading to cover the river water bodies located in the District of Juai which crosses 6 (six villages) namely; Ds.

Abstract

Town expansion not followed by infrastructure development can result many problems andone of them is related to transportation. This research aims to model Trip generation conducted bysome community of housing types in Pematangsiantar town. And the research of this is done toknow and estimate the level of out movement from the housing that will be used for forecasting inorder to overcome all problems at the future period.The primary survey is done by filling thequestionnaire by 86 members of families which are living in three housing type’s area that is luxurious,middle and simple. The result of the questionnaires will be tabulated to become dependent variableand independent variable. Moreover, it will be analyzed by SPSS-12 program. The equation regressionof it will be used to model and awaken the trip of community in some housing types in Pematangsiantartown.From the final result model test, it was gotten that the trip generation in three housing typearea that is luxurious housing type (Y1), middle housing type (Y2), and type housing of simplebuilding (Y3) had been very influenced by amount of family member (X1), amount of the ownershipof car (X3), amount of the ownership of motorcycle (X4) and amount of family go to school (X6).The regression model equations are included by luxurious housing type (Y1) = -0,728 + 1,885 X1+ 0,649 X3 + 0,772 X6, middle housing type (Y2) = 0,600 + 1,300 X1 + 0,900 X3, simple housingtype (Y3) = 0,271 + 1,518 X1 + 0,905 X4.Keyword: Trip generation model, Housing typologies.

Ernawan S.1) , Yuda Al Qadr Latief2)1,2) Jurusan Teknik Sipil Universitas Muhammadiyah MalangAlamat korespondensi : Jl. Raya Tlogomas 246 Malang 65144AbstractHydrological conditions in Indonesia and elsewhere is typical, so not all the way and all the concepts can be used to solve the problem of hydrology in Indonesia, especially in the Upstream Brantas River precisely in Sub Watershed of Metro. Rain is an important input component in the hydrological processes. Rainfall characteristics of which are the intensity, duration, depth, and frequency. Intensity related to the duration and frequency can be expressed by curves Intensity-Duration-Frequency (IDF). IDF curves can be used to calculateflood plan to use a rational method.In this study, daily rainfall calculated by frequency analysis begins by determining the mean maximum daily rainfall, then calculate statistical parameter to choose the most suitable distribution. The time is long dominant rainfall event with the greatest frequency of rain events. The intensity is calculated by using the data of observation.Based on the analysis of the frequency of the rain turns to design return period 2, 5, 10, 20, 50 and 100 years in a row is 49; 70; 86; 111; 132 and 155 mm. The results showed that the amount of time the dominant rain events between 4-8 hours. IDF curves in sub watershed of Metro based on the data observations generally showed a pattern where the rainfall is always preceded by a high intensity then progressively decreases. Besides the greater the return period tend to have higher rainfall intensity. The results of this research could bedeveloped even if it may be modified in accordance with the specific conditions subwatershed of Metro.
