Abstract

In this study the 1-dimensional Schrӧdinger equation was solved using numerical method. The Schrӧdinger equation is solved for the infinite potential well and the quantum harmonic oscillator. The classical 4th order Runge-Kutta method and the modified Runge-Kutta method of harmonic mean are used. The research begins by formulating a second-order differential equation for each problem. This second-order differential equation is then split into two ordinary differential equations so that it can be solved using the Runge-Kutta method. The results obtained from numerical calculations are the wave functions and energy levels for each quantum number n. The results of the wave function of the numerical solution show a very good trend and are in accordance with the wave function of the exact solution. Eigen energy values for each case have been obtained for various values of n. The largest error value of 0.58 % is obtained for the numerical solution using the modified Runge-Kutta method of harmonic mean.

Abstract

The implementation of construction projects requires the use of many natural resources, one of which is construction materials. Construction materials should be well planned, from the process of planning, implementing, and controlling. By doing construction material management, it will minimize the presence of residual materials and residual materials are also not wasted. Management of residual materials from construction projects can be done with the stages of reduse (preventing / reducing), reuse (reuse), recycle (recycling), and salvage (moving). The GBKP Bukit Village church construction project is the object of this study. The purpose of this study is to find out the materials that are most often associated with the church project and to find out what are the controls carried out by construction actors to minimize the presence of residual material. The method used is to provide questionnaires to construction actors to obtain data, then the data is processed with the percentage description method to find out the most frequently residual materials and what residual material control is carried out by the contractor. The results of this study show that reinforcing iron is the material that most often occurs in construction projects. Meanwhile, control of residual materials by recycling is rarely carried out by construction actors in this project because in general construction actors have not felt it is important to recycle construction materials. In addition, construction actors' knowledge of recycling construction materials is also not enough, so construction actors feel that it is better to sell the remaining materials that can be recycled to third parties.

Abstract

Reinforced concrete construction is inseparable from the use of reinforcing steel as a material that resists the tension that occurs in concrete structures. Steel material is used to carry out its duties to cover the weakness of concrete in terms of tensile loads. Tests are carried out to determine the magnitude of the difference in tensile strength of the reinforcing material being tested. Experiments on steel with a minimum yield stress of 280 MPa which is also known as plain reinforcing steel and reinforcing steel with a yield stress of at least 420 MPa or also known as fin reinforcing steel. The variation used in this test lies in the diameter of plain reinforcing steel with diameters of 8, 10 and 12 mm. Fin reinforcement steel with diameters of 10, 13 and 16 mm. The test results show that the deeper the reinforcing steel, the greater the required tensile strength. Other results show that fin steel reinforcement has a higher tensile strength than plain reinforcing steel.

Abstract

To make paving blocks, the material used is material from natural resources that are difficult to renew, so alternative resources such as industrial waste are needed. The industrial waste is underutilized, so it can be used as material for making paving blocks. There is industrial waste that has not been utilized optimally in Klaten. One of them is the steel casting industry center in Ceper which produces slag waste and the palm flour processing industrial center in Tulung which produces solid waste onggok. The addition of onggok ash to the slag paving block is expected to be able to achieve the compressive strength of the paving blocks according to SNI standards. Waste used as an alternative resource is expected to eliminate illegal industrial waste disposal. Waste treatment can make waste more valuable and reduce environmental burdens such as exploitation of natural resources. In the future, slag and slag are no longer considered as waste, but as new resources. Paving blocks are printed manually, then tested to determine their compressive strength. The compressive strength values of normal paving blocks and slag paving blocks with variations in the percentage of onggok ash 5%, 10%, 15% respectively are 10.56 Mpa; 11.47 MPa; 8.44 MPa and 7.63 MPa. The conclusion of this study, using SNI 03-0691-1996 is that the slag paving block with 5% onggok ash meets the Quality D standard. This mixture also shows optimal compressive strength and an increase in compressive strength of 0.91 MPa compared to normal paving blocks.

Abstract

Persimpangan jalan Rumah Sakit Haji Adam Malik Medan, merupakan bagian dari jalan utama yang ada di kota Medan yang mana aktivitas di daerah jalan ini cukup besar. Selain itu ruas jalan ini merupakan jalur transportasi darat yang digunakan masyarakat bila hendak menuju Rumah Sakit Haji Adam Malik Medan. Sehubungan dengan hal tersebut, persimpangan jalan Rumah Sakit Haji Adam Malik Medan sering mengalami tundaan karena volume kenderaan yang melalui simpang tersebut, terutama dari arah kota Medan menuju Rumah Sakit Haji Adam Malik cukup besar, sehingga mengalami perlambatan dan percepatan kenderaan yang membelok dipersimpangan dan dapat menyebabkan konflik antara sesama kenderaan yang melintasi simpang tersebut dari lengan jalan lain.Telah dilakukan penelitian dan Evaluasi Kinerja Simpang Bersinyal di Persimpangan Rumah Sakit Haji Adam Malik Medan dengan melakukan survey langsung kelapangan untuk memperoleh data lalu lintas baik yang masuk menuju Rumah Sakit Adam Malik maupun yang keluar dari Rumah Sakit Haji Adam Malik. Data yang diambil adalah semua jenis kenderaan yang melewati simpang baik kenderaan yang belok kiri maupun belok kanan, serta besarnya Panjang antrian. Penelitian dilakukan selama 21 hari dan data tersebut diolah dengan metode MKJI 1997.Berdasarkan evaluasi yang dilakukan, jumlah pengguna transportasi dari hasil survey di lapangan didapat arus jam puncak pukul 07.00 WIB - 08.00 WIB sebesar 1.162 smp/jam dengan kendaraan arah jalan Jamin Ginting-Berastagi sedangkan dari arah  Rumah Sakit Haji Adam Malik 375 smp/jam yang di peroleh dari perhitungan. Maka hasil yang diperoleh data lalu lintas, tidak terlalu tinggi dan tidak sesuai dengan standar MKJI 1997 untuk menghidupkan lampu lalu lintas. Oleh karena itu solusi yang tepat dilakukan saat ini adalah agar median jalan yang mengarahkan kenderaan keluar masuk Rumah Sakit Haji Adam Malik Medan ditutup dan membuat U-Turn  (putar balik) di arah Simpang Selayang dan di arah Berastagi.
