ANALISIS HOMOGENITAS SELF COMPACTING MORTAR MENGGUNAKAN SERAT POLYPROPYLENE BERDASARKAN KECEPATAN PERAMBATAN GELOMBANG ULTRASONIK (UPVM) Ma'arif, Faqih Widodo, Slamet Santoso, Agus Nowadays, Non Destructive Tests have been applied in many qualityevaluations of existing concrete structures. One of the Non Destructive Tests (NDT)is based on Ultrasonic Pulse Velocity (UPV). The use of UPV method among othersare to estimate the strength of concrete, to detect the presence of crack, to measurethe homogeneity of concrete, the thickness of concrete slab, and also to estimate thediameter of the embedded steel reinforcement. The NDT technique will apply on thisresearch. This research used 24 cylinder test samples in four groups, which werereference cylinder (SR), cylinder-1 (S-01) with 0.5 kg/m3 of fibers, cylinder-2 (S-02)with 1.0 kg/m3 of fibers and cylinder-3 (S-03) with 1.5kg/m3 of fibers. Those cylinderswere of 150 mm in diameter and 300mm in height. The Ultrasonic Pulse Velocity(UPV) test was conducted with direct test method. The data are then analyzed usingstatistical program. The test result showed that the addition of polypropylene fibersoptimum and pulse velocity were of 1kg/m3 and 3,19km/s respectively. The increasepulse velocity transmitter higher on variation of fibers 1kg/m3 is 9,12% in comparisonto reference cylinder. The statistical test indicated that the signifinance value (2-tailed test) is homogeneity sample. This means that the ultrasonic pulse velocitymethod can used to knowing of homogeneity self compacting mortar using fibers.Keyword: Homogeneity, polypropylene, Ultrasonic pulse velocity Method Universitas Negeri Yogyakarta 2015-02-13 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/3681 10.21831/inersia.v7i2.3681 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 7 No. 2 (2011): Desember 2528-388X 0216-762X 10.21831/inersia.v7i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/3681/3154 Copyright (c) 2022 Faqih Ma'arif, Slamet Widodo, Agus Santoso

PENGARUH PENAMBAHAN SUPERPLASTISIZER TERHADAP CAMPURAN BETON RINGAN YANG MENGGUNAKAN STYROFOAM Kusnadi, Kusnadi Sulistyorini, Dewi The risk of failure of structures effect of earthquake be high due to the heavyvolume of concrete has a fairly high (2400 kg/m3). Advances in technology and theimpact of the economic crisis encourage construction of infrastructure use concretemasonry units under 1900 kg/m3 in weight. The use of lightweight concrete is thefiller material styrofoam intend at non structural components like wall. One of theproblem of making lightweight concrete using styrofoam is the low value of slump, sothat the mix becomes difficult (low workability). It is therefore necessary to addmaterial superplastisizer This research used 20 cylinder test samples. Thecomposition of the mixture consists of sand, cement and grain of styrofoam. Thestyrofoam in concrete is 20% in volume. The Sample variation consists of lightweight concrete using styrofoam without superplastisizer is four cylinder, with addedsuperplastisizer four cylinder were 0.5%, 1.0%, 1.5% and 2%, respectively in weightof cement. The results showed the addition of superplastisizer 0.5%, 1%, 1.5% and2% of the cement weight increases the value of slump were 100%, 183%, 216% and507% respectively. The addition of superplastisizer 0.5%, 1%, 1.5% and 2% of thecement weight increase ceompression strength were 8.48% 4.25%, 12.67% and17.37% respectively. The addition of superplasticizer will increases the slump for thesame water content in fresh concrete, so can increase the compressive strength ofconcrete cylinder.Keyword : beton styrofoam, workabilitas, superplasticizer Universitas Negeri Yogyakarta 2015-02-13 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/3684 10.21831/inersia.v7i2.3684 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 7 No. 2 (2011): Desember 2528-388X 0216-762X 10.21831/inersia.v7i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/3684/3157 Copyright (c) 2022 Kusnadi Kusnadi, Dewi Sulistyorini

EULER BUCKLING FAILURE MODEL AT GALVANIZED PIPE INFLUENCED BY HOLE DETERIORATION AS PITTING CORROSION MODELLED EXPERIMENTAL APPROACHMENT Iman, Miftahul Korosi adalah fenomena alam yang tidak dapat dihindari. Hampir seluruhlogam yang mengandung unsur paduan Ferrit akan mengalami peristiwa oksidasisebagai penyebab korosi. Banyak konstruksi sipil yang berada di lingkungan agresifdan merupakan konstruksi-konstruksi vital yang melayani kebutuhan masyarakatbanyak, semisal pelabuhan, off shore structure, crane dan lain sebagainya kurangmemperhatikan dampak korosi yang terjadi pada konstruksi tersebut. Hal inidisebabkan salah satunya oleh formulasi analitik satu dimensi untuk menentukanbeban kritis (Pcr) tidak dapat memberikan model yang optimal terhadap batangaksial tekan dengan penampang yang tidak solid (hollow section) seperti halnyadengan tube atau pipe dari sebuah struktur aksial tekan dengan adanya pengaruhcacat berupa lubang yang dimungkinkan akibat reaksi korosi dalam bentuk pitting.Penelitian ini mengembangkan model laboratorium yang mengunakanprototype pipa galvanis sebanyak 16 sampel yang terdiri dari 3 sampel untuk ujipendahuluan dan sampel lainnya dengan lubang pada tengah tinggi kolom denganrincian 3 sampel untuk lubang tunggal, selanjutnya disebut sebagai Single HolePitting (SHP) dan lainnya untuk sampel dengan jumlah lubang lebih dari satu yangterdiri dari sembilan sampel, selanjutnya disebut sebagai Multi Hole Pitting (MHP).Sampel MHP dan SHP memiliki korelasi sedemikian rupa terhadap parametergeometrik yang telah ditentukan sebelumnya.Model eksperimen dalam penelitian ini memberikan nilai cukup baik dan lebihmendekati nilai beban kritis berdasarkan hasil analitik metode Euler. Meskipundemikian nilai tersebut sangat tergantung pada besaran nilai modulus elastisitas (E)yang berikan pada formulasi Euler tersebut. Hasil penelitian menunjukkan Pcr bendauji SHP lebih rendah daripada benda uji MHP (D24 = 15382,48 N < 6D4 = 15663,2N). Begitu juga halnya dengan pengujian laboratorium namun efek 3-arah tekukyang ditimbulkan oleh pipa galvanis menunjukkan perilaku yang unik terutama padakekakuan dan orientasi tekuk yang terjadi. Penelitian ini juga membuktikan bahwategangan dan kosentrasi tegangan yang terjadi pada saat tekuk belum mencapaitegangan leleh.Kata kunci: Tekuk Euler, Korosi pitting, modulus elastisitas Universitas Negeri Yogyakarta 2015-02-13 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/3689 10.21831/inersia.v7i2.3689 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 7 No. 2 (2011): Desember 2528-388X 0216-762X 10.21831/inersia.v7i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/3689/3162 Copyright (c) 2022 Miftahul Iman

When a column is weak, itwill cause total failure to the structure. This study examined the behavior of columnreinforced with mortar jacketing method and wire netting. The objective of this studywas to identify the contribution of the reinforcement to the shear strength and columnductility. Four column specimens were made. They consisted of one original column(as comparison) in square shape of 150 x 150 mm, and 700 mm height andfoundation plate in 1200 x 700 mm with 250 mm thickness and three specimens insame dimensions and strengthened by mortar jacketing to become column withround section in 220 mm diameter and 730 mm height. Longitudinal reinforcementand wire netting in 1.7 mm diameter and consisted of small squares of 25 mm x 25mm with 1 layer strengthening (KP-1). Two layers (KP-2), and 3 layers (KP-3) wereused as the mortar jacketing. Sika Grout 215 New was used as the filler. Loadingtype used was constant axial and cyclic lateral to simulate earthquake by using thedisplacement control method. The results showed that in KP-1, KP-2 and KP-3reinforced column, their lateral load capacities increased by 90.263%, 101.985%,124.196%, respectively, than the average original column (KA-1).

EULER BUCKLING PATTERN Of AXIAL LOAD CHS MEMBER MODELLED IN FRAME ELEMENT AND SHELL ELEMENT SAP2000 VERSION 11,00 UTILIZED Iman, Miftahul Stabilitas adalah salah satu pertimbangan utama dalam perencanaan struktur gedung. Begitu banyak kegagalan struktur yang diakibatkan oleh persoalan stabilitas, terutama pada komponen struktur yang menerima beban aksial. Berdasarkan teori dan praktek, jenis tumpuan yang berbeda akan memberikan pola tekuk yang berbeda juga. Perbedaan ini akan berakibat kesalahan dalam analisa beban kritis yang dengan sendirinya menjadi tidak akurat lagi. Pertimbangan keakuratan dan ketepatan dalamprediksi beban kritis ini maka telah banyak perangkat lunak dari analisa struktur yang telah dikembangkan, khususnya analisa tekuk dan SAP2000 adalah salah satunya. Penelitian ini berfokus pada kajian numerik yang berdasarkan pada metode elemen hingga dari sebuah batang aksial tekan yang mempertimbangkan kelangsingan untuk mendeskripsikan kegagalan tekuk. Model pengujian diperoleh dari salah satu sampel penelitian oleh Miftah (2010) yang menggunakan galvanized pipesebagai batang tekan yang dimodelkan sebagai circular hollow section , CHS. Selanjutnya dengan bantuan SAP2000 versi 11,00 akan dibuat pendekatan batang tersebut dengan model frame 3D dan model shell 3D dengan menambahkan spherical dome shell pada ujung-ujung model tersebut untuk kemudan dilakukan analisis dengan analisa statik untuk tekuk linear. Akhirnya kedua model tersebut dibandingkan dan kemudian dari keduanya akan dilakukan verifikasi terhadap nilai eksak (Euler analisis) dan hasil uji eksperimen. Hasil penelitian menunjukkan bahwa dengan melakukan penambahan spherical dome pada ujung-ujung cylindrical shell model akan membuat beba n aksial terkosentrasi pada tumpuan dalam hal ini meggunakan tumpuan sederhana sehingga akan memberikan pola tekuk yang serupa dengan model Euler satu dimensi. SAP2000 versi 11 memberikan ketelitian yang sangat tinggi terhadap hasil analitik yaitu 0,028%. Selain itu, dari kombinasi spherical dome-cylindrical shell pada SAP2000 versi 11,00 juga memberikan ketelitian yang cukup baik yaitu -5,47% dan menunjukkan bahwa dengan model ini beban kritis yang dicapai jauh lebih konservatif dibandingkan dengan menggunakan model frame 3D.

The test specimen was made of a mixture of cement, sand, coarse aggregate of plastic pellets and water. The design of concrete mix by Indonesian National Standard (SNI) with normal concrete compressive strength of 10 MPa was planned. Variations of the specimen lied on the mixture of stone ash and sand, respectively for 0% and 100%, 25% and 75%, 50% and 50%, 75% and 25%, and 100% and 0%. The object of the research was a cylinder diameter of 100 mm and height of 200 mm for testing of weight-volume and compressive strength, and a cylinder diameter of 150 mm and height of 300 mm for testing of split tensile strength. The results of the research showed that the higher level volume of stone ash in concrete, the higher weight-volume and compressive strength. It was increased in split tensile strength of the concrete levels of 0% to 50% stone ash, and it was decreased in levels of 75% and 100% stone ash. The results of weight-volume testing showed that all variations of concrete were classified as lightweight concrete because it had weight-volume of less than 1850 kg/m3 (Balitbang Kimpraswil, 2003b). Neville and Brooks (1987) also classified the concrete as lightweight concrete because it had weight-volume evenly less than 1800 kg/m3 and 1900 kg/m3. The results of compressive strength testing showed that concrete with stone ash content 0-75% were classified as very lightweight structure because it had compressive strength of less than 6.89 MPa, while levels of 100% were categorized as very lightweight structure with compressive strength from 6.89 to 17.24 MPa (Balitbang Kimpraswil, 2003b). According to Neville and Brooks (1987), concrete with stone ash content 0-75% were classified as lightweight concrete for heat resistant (compressive strength of 0.7 to 7 MPa), while levels of 100% were categorized as lightweight concrete for masonry (compressive strength of 7-14 MPa).Keywords: Polypropylene (PP), stone ash, compressive strength, split tensile strength, lightweight concrete Universitas Negeri Yogyakarta 2015-05-25 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/4427 10.21831/inersia.v10i1.4427 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 10 No. 1 (2014): Mei 2528-388X 0216-762X 10.21831/inersia.v10i1 eng https://journal.uny.ac.id/index.php/inersia/article/view/4427/3847 Copyright (c) 2022 Nur Aisyah Jalali, Hasmar Halim

PERILAKU MEKANIK TARIK BAMBU DAN POTENSI APLIKASINYA SEBAGAI PERKUATAN TANAH PADA TIMBUNAN Suwartanti, Suwartanti ABSTRACTThe main obstacle in building a construction in soft soil is the big settlementwhich occurs in such soil. One of the techniques to solve this problem is tohamper geosynthetics on this soft soil and create a compacted embankmentfrom good soil above the soft soil. The application of this technique is quiteeffective, but due to economic problem and environmental awareness, the useof another material which is cheaper and comes from nature is in urgent need.In the past our ancestors have used bamboo as soil reinforcement. Unfortunatelythe publications and researches concerning this matter are still very few.This study is aimed to investigate the tensile strength of woven bambooand its potential application for soil reinforcement in an embankment. Threevariants of bamboos are used in the experiment. The samples are taken fromthe outer parts (skin) and inner parts, with and without nodes. The shape anddimension of the samples are designed to represent the actual shape anddimension of woven bamboo.From the experiment, the maximum tensile strength obtained from tensilestrength and strain analysis is 395.533 kN/m'. The outer part of bamboo iscategorized as brittle material while the inner part is ductile. Based on thesefindings and considering bamboo's rough surface and its lifetime, bamboo ispotential for soil reinforcement in an embankment to replace a particular functionof geosynthetics.Keywords: bamboo, soil reinforcement, embankment Universitas Negeri Yogyakarta 2016-03-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/8233 10.21831/inersia.v1i1.8233 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 1 No. 1 (2005): Maret 2528-388X 0216-762X 10.21831/inersia.v1i1 eng https://journal.uny.ac.id/index.php/inersia/article/view/8233/6880 Copyright (c) 2022 Suwartanti Suwartanti

KEBUTUHAN DEBIT UNTUK FLUIDISASI 01 MUARA SUNGAI- DAN ALUR PELAYARAN Widiyanto, Wahyu ABSTRACTFluidization method is one of the alternatives to maintain river mouth andharbour entrance. It is expected to substitute the role of maintenance dredgingthat is high cost and often inefficient for small volume of dredging. A series ofresearch is conducted to understand the fluidization method but there has beenlittle confidence whether fluidization process can run when the system isimplemented in the field. Hence, fluidization model of large scale is expected toenhance confidence.The objective of the present study is to obtain flow rate required forfluidization. The study used two dimensional physical modelling of large scale. Itwas conducted by testing various sediment thickness (burial depth of pipe) from25 cm to 150 cm in a large concrete well. Several parameters were observed onthe experiments. Performances of one and three holes of fluidizer pipe wereobserved too.The flow rate requirement increases linearly with sediment thickness. For 1hole of fluidizer pipe, the flow rate requirement approaches Qh =0,45 db + 0,40.While 3 holes of fluidizer pipe requires flow rate as Qh =1,44 db + 0,16. Wheredb is sediment thickness. Comparison between the performances of 1 holeand 3 holes of pipe show that holes spacing significant to fluidization. Thedistance between holes should not be too long. Cooperation of holes mayreduce flow rate requirement.Keywords : fluidization, dredging, sediment Universitas Negeri Yogyakarta 2016-03-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/8243 10.21831/inersia.v1i2.8243 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 1 No. 2 (2005): September 2528-388X 0216-762X 10.21831/inersia.v1i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/8243/6886 Copyright (c) 2022 Wahyu Widiyanto

KARAKTER FORMAL BANGUNAN 01 KAMPUS UNY KARANG MALANG Ikhwanuddin, Ikhwanuddin ABSTRACTThe Karangmalang campus of Jogjakarta State University is a continuously developed area. At least, it can be seen from the appearance of some new buildings in these area. It is a good thing, but in the other, some worries appear as those new buildings were designed imperfectly. It seems that those new buildings were designed in different sight one to another.. "Is it because of the fully unclear and incomplete guideline? ". The clear and complete guideline is an important aspect to arrange the area; lack of such guideline will cause a messy area or an illegible one. Legibility is one aspect that Lynch (1960) proposed to create a good area. To get knowledge about legibility of an area, an understanding on formal character is needed. This is an important reasonwhy this research must be done.The research used quantitative research method in positivistic paradigm.Each object is observed and the information is collected in form of sketch ofplan and building's fa9ades, and also photographs. The objects of researchwere six offices of Dean in Jogjakarta State University consist of FBS, FIK, FT,FIS, FMIPA and FIP Dean's offices. The information had been analyzed ingraphical and verbal forms followed by quantitative manner to identify thedominant aspects of formal character of each object.This research reveals some formal characters of dean's office building inJogjakarta State University area. Those formal characters are: a) the axis is strong, b) the symmetrical form is very strong, c) the proportion is 1:3, d) the roof angle is 30 Q and 35Q, e) the hyrarcy is on one level in horizontal as well asvertical direction, f) the rythm is "a-b-c-b-a " pattern, and g) the dominant datumis ventilation hole.Keyword: legibility, formal character, the dean's offices building Universitas Negeri Yogyakarta 2016-03-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/8303 10.21831/inersia.v2i1.8303 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 2 No. 1 (2006): Maret 2528-388X 0216-762X 10.21831/inersia.v2i1 eng https://journal.uny.ac.id/index.php/inersia/article/view/8303/6928 Copyright (c) 2022 Ikhwanuddin Ikhwanuddin

MODEL MATEMATIK ANGKUTAN LIMBAH PADA SALURAN TERBUKA Purwantoro, Didik This research is aimed to know the process of waste transportation on theopen-channel using numerical model. This model is chosen because of some reasons, for example the complication of the river tissue, the influence of ebb which causes difficulty to conduct analytical problem solving. The other excess of this numerical model is cheaper and easier than conducting measurement of waste rate in the field.The equa~on of waste transportation can be formulated as the two physics phenomenon, Le. advection and diffusion process or long dispersion of river. In the solving of equation of waste transportation, each of the components was analyzed separately. The advection part was done first, and the diffusion part was finished then. The advection equation was done using Lagrange interpolation, and the diffusion equation was done using differential method to explicit scheme.The result of the research shows that the use of Lagrange interpolation upto order 4 is still be good enough to finish advection equation for numberCourant 1, 0,75 and 0,5. For number Courant 0.25, numerical mistake causingconcentration degradation of 2.3 0/0. In the diffusion equation, the result of computationusing differential method up to explicit scheme yielding degradation ofwaste concentration from 10 gr/I become 4,96 gr/I for the diffusion coefficient ofKx =10 m2/sc and become 3,73 gr/I for the diffusion coefficient of Kx = 20 m2/sc.

KAJIAN KUAT LEKAT TULANGAN PADA FLOW!NG CONCRETE DITINJAU DAR! TINGGI JATUH PENGECORAN Aspin, Nuriyadin Eko Raharjo AbstractPumping method that widely used in the stage of concreting forhigh rise building construction, will lead the fresh concrete into the risksof bleeding and segregation that can caused inadequate concrete qualitydue to the presence of more pores volume in hardened concrete.Interfacial transition zone between plain concrete and reinforcing bar is amain factor that dominantly determine the mechanical strength ofreinforced concrete members as a composite material. Fresh concretecharacteristics, casting method, and free fall height will mainly affect thebond strength of a reinforced concrete structural member. This researchaimed to investigate the effects of free fall height in the concrete castingon the bond strength of concrete reinforcement.Concrete material that used in this research mixed using OrdinaryPortland Cement with 0.45 of water-cement ratio, 1% of polycarboxylatebased high range water reducer by weight of Portland cement, and a 16mm of deformed steel reinforcing bar with 403.06 I\~Pa of yield strength.The experiment was done on the free fall heights of 0 em, 30 em, 75 em,100 em, 200 cm, and 300 em. Investigation of concrete compressivestrength was done using 18 15x15x15 cm3 standard cubes, and bondstrength using 18 standard samples of reinforcing bar casted in15x15x15 cm3 concrete cubes.The experimental test indicates that free fall height significantlyaffects bond strength of steel reinforcement in a reinforced concretestructural member. The optimum bond strength was achieved on 30 cmof free faU height, and the failure of the samples meet with rull-outmechanism. This result can be explained due to the presence ofgravitational force that lead the fresh concrete into an initial compactingprocess by its own weight, when bleeding and segregation do not existit: the casted fresh concrete.Keywords: strength of steel reinforcement, floowing concrete,superplasticizer Universitas Negeri Yogyakarta 2016-03-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/8316 10.21831/inersia.v3i1.8316 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 3 No. 1 (2007): Maret 2528-388X 0216-762X 10.21831/inersia.v3i1 eng https://journal.uny.ac.id/index.php/inersia/article/view/8316/6940 Copyright (c) 2022 Nuriyadin Eko Raharjo Aspin

Model Matematik Aliran Air Bawah Bendung Didik Purwantoro, Pramudiyanto, Dam is a structure which is the main function is to dammed up theflow ofthe river so that it gets the sum ofa specific volume ofthe water. The dam can be builtfrom concrete, stone, sand,. clay or combinations between them. As it function to resist the water flow ofthe river, the dam must be controlledfrom its displacement or turning over came fromthe water pressure. On the clay-typed dam, the safety value is also determinedfrom the water "rembesan ". As its affected to the stability of the dam, "rembesan" can caused the leak ofthe water to the dam and then become ruin. To anticipate those phenomenon of "rembesan" need a ''pengamatan cermat" to the "rembesan" activity of the dam so the development of "rembesan " activity can be detected, find the problem and then appropriate actions can be taken to solve them, and then more bigger problem can be avoided. The next important aspects are the dam s "rembesan" and "bocoran". On a specific circumstances, beside the "rembesan" and "bocoran" which can caused loosing the water, the "bocoran" can broke down the stability ofthe surrouding structure nearthe dam. The underground "rembesan" on a dam can be determined through numerical model with the finite element method. The utilization ofthe finite element method on the case ofthe dam "rembesan" seem like a new method compared with the finite difference method.

PENGARUH VARIASI DEBIT ALIRAN TERHADAP GERUSAN MAKSIMAL DI BANGUNAN JEMBATAN DENGAN MENGGUNAKAN PROGRAM HEC-RAS Didik Purwantoro, Ichsanul Barokah, This research aims to find The maximum scour depth occurred in building bridges using HEC -RAS software . Maximum scour modeling results can be used to identify and estimate thestability of the structure of the bridge. This research using software HEC-RAS v. 4.1.0. Stagesof modeling programming includes several data input process, that is: the geometry data inputstream, bridge geometry data input, input the data flow, data input on bridge scour. Modeling isdone with the flow rate changes on any one process is running. Modelling maximum scour whoreviewed that is on the pillars of the bridge. This research result of this modeling with the flowrate variation, it can be seen that the discharge 5.87 m³ / s to 905.23 m³ / s began to increasethe depth of scour at the pillars. Then on debit 905.23 m³ / s to 1080.15 m³ / s scour depthexperience stability pillar, at a depth of 1.76 m..Keyword: HEC-RAS, Scour, The flow rate Universitas Negeri Yogyakarta 2016-07-12 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/9965 10.21831/inersia.v10i2.9965 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 10 No. 2 (2014): Desember 2528-388X 0216-762X 10.21831/inersia.v10i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/9965/7862 Copyright (c) 2022 Ichsanul Barokah, Didik Purwantoro

ANALISIS KELAYAKAN ELEVATOR STUDI KASUS HOTEL GRAND TJOKRO DAN MATARAM CITY YOGYAKARTA Sumardjito, Achmad Syaifudin, The purpose of the study ist o e x ami n e e l e v a t o r p a s s e n g g e r f o r Ho t e l GrandTjokro Yogyakarta (HGTY) building and Apartment and Hotel Mataram Yogyakarta rewards toelevator requirement as a condition of a residential building needs in terms of capacity, speedand amount. The approach of the study was case study. This study conducted by collectingbuilding data (builds drawing) and specifications of the building elevators. The Analysiselevators using 2 references plan, which are taken from the table chart of Benjamin Stein in thebook Mechanical And Electrical Equipment for Building (MEE) and the empirical way of HartonoPurbo (2007). Based on the analysis of table sandgraphsof MEE, the result of the study showedthat HGTY requires 2 lifts (1050 kg, 2 m/s), as well as to AHMCY needs 4 lifts (1000kg, 1.75m/s). While empirical manner indicates that HGTY need 3 lifts (1050kg, 0.63 m/s) and 2 lifts ifthe speed of 2m/s, as well as for AHMCY, elevators analysis is made of 1 zone system and 2zone system. The system needs to lift 1 zone as much as 2 pieces lifts for apartments and 3pieces lifts to the hotel, and for the 2 zone system each require 4 lifts (1000kg, 1.75 m/s). Basedon the MEE concluded that (1a) HGTY elevators, speed meets there quirements, but thenumbers cannot be analyzed, because speed does not fulfill the requirements for residentialbuildings. As for the (1b) AHMCY elevators, speed and capacity have fulfilled the requirements,but the number was not sufficient to fulfill there quirements. Based on empirical way concludedthat (2a) HGTY elevators have fulfilled there quirements interms of capacity and speed, but thenumber was not sufficient to fulfill the requirements, while for (2b) AHMCY elevators, speed,capacity and quantity to fulfill the requirement soft the system when made 1 zone, but thenumber was not sufficient to fulfill the requirements when made 2 zone system.Keywords: feasibility, multi-storey buildings, passenger elevators Universitas Negeri Yogyakarta 2016-07-12 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal.uny.ac.id/index.php/inersia/article/view/9966 10.21831/inersia.v10i2.9966 INERSIA lnformasi dan Ekspose Hasil Riset Teknik Sipil dan Arsitektur; Vol. 10 No. 2 (2014): Desember 2528-388X 0216-762X 10.21831/inersia.v10i2 eng https://journal.uny.ac.id/index.php/inersia/article/view/9966/7863 Copyright (c) 2022 Achmad Syaifudin, Sumardjito d1688f4dc6292367888a486a70c78604
