Publisher : Program Studi Teknik Sipil Fakultas Teknik Universitas Atma Jaya Yogyakarta

Salah satu metode yang sering digunakan dalam mendeteksi kerusakan elemen dalam struktur adalah metode vektor beban penentu lokasi kerusakan. Hal ini dikarenakan metode ini cukup mudah untuk digunakan dan memberi hasil yang cukup memuaskan dalam mendeteksi kerusakan struktur. Pada penelitian-penelitian sebelumnya, metode vektor beban penentu lokasi kerusakan ini telah banyak diaplikasikan ke berbagai jenis (tipe) struktur misalnya pada struktur balok, struktur rangka, struktur portal, dan lain sebagainya, Oleh karena itu, pada penelitian ini, metode beban penentu lokasi kerusakan ini diaplikasikan pada struktur thick plate. Terdapat dua skenario pembagian elemen dengan masing-masing tiga skenario kerusakan. Skenario pembagian elemen yaitu struktur thick plate akan dibagi menjadi 4 elemen dan 81 elemen. Pemodelan yang digunakan adalah dengan menggunakan metode elemen hingga dengan mengasumsikan elemen pelat tersebut sebagai elemen eight-noded quadratic quadrilateral plate bending. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan dari metode vektor beban penentu lokasi kerusakan dalam menentukan elemen rusak. Berdasarkan hasil yang didapatkan, metode vektor beban penentu lokasi kerusakan cukup akurat dalam menentukan elemen yang diasumsikan mengalami kerusakan.

The foundation has a function to hold the load in the form of axial load, lateral load and moment. The axial load on the pile foundation is supported by the pole end resistance and pile friction, while the lateral load on the pile foundation is supported by the relation of the blanket area along the pile with the ground in the lateral direction. Lateral load causes lateral deflection in which the magnitude of deflection must not exceed the permissible lateral deflection limit of 2.54 cm. The determining factors in lateral deflection are the type of pile foundation, soil type, and the magnitude of the force that occurs. The foundation of a single pile in which the number of one pile when embedded in clay soil needs to be investigated for the magnitude of lateral deflection that occurs, this is due to the changing nature of the clay when under the influence of high or low water content. The foundation of the pile uses a concrete head with the condition of a free end with a cylindrical shape with a diameter of 60 cm that is not solid with a wall thickness of 10 cm and a compressive strength of concrete of 60 MPa. Clay soil data uses soil drilling test data in Wirosari, Grobogan, Central Java. The planning method used is the finite element method (PLAXIS) and the finite difference method (p-y curve and the ALLPILE program) with lateral load variations of 10 kN, 15 kN and 20 kN given to the top end of the pole with the principle of giving trial and error loads. The results of the calculation of the lateral deflection of the pile on the p-y curve method with finite difference resolution, the ALLPILE program, and the PLAXIS program respectively with a lateral load of 10 kN are 0.0629 cm; 1.21 cm; 0.27 cm, lateral loads of 15 kN are 0.0943 cm; 2.13 cm; 0.4051 cm, and a lateral load of 20 kN is 0.1258 cm; 3.14 cm; 0.5402 cm. Thus the lateral deflection load limit is 15 kN, so as not to exceed the permissible lateral deflection limit of 2.54 cm. The recommended method used is the ALLPILE program to better get the level of security from the lateral deflection of the pole when applied in the field.

PT Hasnur Riung Sinergi conducts coal mining using the open pit method, so that mining activities are directly related to outside. The problem is condition of the trench that unable to drain run off, so that makes overflows and inundates the roads and other mining areas. The research aims to design a trench that able to drain the planned run off and calculate the cost of making a trench. The method used is to calculate run off flow to determine the dimensions of the trench, then calculate the productivity of the machine to determine the cost of fuel requirements and the wages of the heavy equipment operator in making the trench. Based on the analysis of rainfall data obtained rainfall intensity of 53.58 mm/hour. There are 7 catchment areas that produce different amounts of run off. Design of a trapezoidal trench for each DTH, the trench on DTH 1, DTH 2, DTH 3, DTH 4 will be made in the pit and useful for flowing run off into the pit leading to the sump, while the trench on DTH 5, DTH 6, DTH 7 will be made outside the pit and useful for flowing run off that is outside the pit to the settling pond. The trench manufacturing work requires 2 PC200 komatsu backhoe machines with excavation time of 11 days. The cost to purchase fuel is Rp.27.846.000 and the cost to pay the operator is Rp.2.970.000. The total cost required for the work of making trenches is Rp.30.456.000. The design was made as a reference for companies in making trenches in the mining area to control run off so as not to interfere with mining activities.

The traffic jam that occurred on Selokan Mataram Street specifically at the intersection of Selokan Mataran Street - Wahid Hasyim Street gave rise unofficial officers or commonly referred to as "Pak Ogah" who took over the police to regulate the traffic. Therefore this research aims to study how the influence of unofficial officers on the performance of the intersection at the Selokan Mataram Street - Wahid Hasyim Street (OB Intersection). The survey was conducted for 2 days which included vehicle volume surveys, vehicle speed surveys, queue length surveys and driving behavior surveys. The results of the VISSIM modeling analysis showed that one-way system management was more effective than unofficial officer with an average delay value of 75.58%. Meanwhile, the length of the queue has decreased and increased. Decrease in the value of the queue length occurred in the north and south by 43.54% and 37.22% and an increase in the west by 31.17%. However, the value of this increase was not as much as the condition of unofficial officers at 78.90% of the existing conditions.

Kapasitas beban lateral pondasi tiang (Pu) merupakan hal utama untuk perencanaan konstuksi dengan beban lateral yang cukup dominan. Kapasitas Pu didasarkan pada kondisi keseimbangan resultan gaya pada tiang dan ketahanan tanah lateral serta distribusi tekanan tanah PL sepanjang kedalaman tiang berdasarkan metode konvensional, tetapi sulit diterapkan pada tanah nonhomogen, karena kondisi tanah nonlinier terhadap kedalaman. Insitu test yang paling sering digunakan karena mudah, cepat dan hemat biaya adalah cone penetration test (CPT), yang memberikan profil tanah secara kontinu, dan lebih mendefinisikan jenis lapisan, ketebalan, dan kepadatan dari masing masing lapisan. Meskipun jarang disebut dalam literatur tentang penggunaan data CPT untuk menganalisa perilaku defleksi pondasi tiang, beberapa peneliti menyatakan hubungan antara resistensi kerucut qc dan tahanan lateral tanah Pu di sepanjang kedalaman tiang. Salah satu metode yang menyajikan pengembangan metode kurva p-y untuk pondasi tiang dengan dasar resistensi penetrasi kerucut qc adalah Bouafia, A. (2014). Berdasarkan pengembangan oleh Bouafia, penulis menganalisa hubungan antara resistensi kerucut qc dan ketahanan lateral tiang Pu untuk menentukan beban lateral pondasi tiang pada tanah lunak di Wates, Kulon Progo DIY dan dibandingkan dengan teori Broms 1964; metode Kurva p-y, dan pengembangan rumus Bouafia, dengan kekakuan tiang, jenis tanah dan defleksi maksimum yang sama maka diperoleh sebagai berikut, teori Broms, LBroms=14,16m ; PuBroms=32,4ton ; MBroms=19,88tonm. Metode Kurva p-y, Lp-ycurve =14,4m ; Pup-ycurve s=28,0ton ; Mp-ycurve =7,50tonm dan Metode Bouafia, LBouafia =17,9m ; PuS2bouafia=34ton; PuS4bouafia=14,8ton; MS2bouafia =11,3tonm ; MS4bouafia =4,9tonm.

Flood events often occur in Indonesia so that quite a lot of people researched about the movement of floods and flood monitoring in the Watershed. The location of the study was carried out by the Way Sekampung river in Way Kunyir located in the Pringsewu district, Lampung province and is located downstream of the Batutegi dam. Flood tracing is intended to analyze the chances of a flood in the form of a flood hydrograph with or without using the Routing method and find out the results of some Routing methods in the watershed. The Routing method used in this study is Lag, Lag and K and Muskingum. The HEC-HMS modeling results state that peak discharge data when without Routing is greater than entering the Routing parameter. This is because entering the Routing parameter in modeling is very influential at peak times so that it affects the peak discharge at the watershed outlet. As a result of Muskingum Routing, the peak discharge is lower than before entering the flow routing, this is due to the occurrence of reservoirs along the river so that the peak discharge becomes lower than without Routing. The results of Lag Routing and Lag and K Routing are peak discharge decreased compared to before entering the Routing parameter. what should have happened to the peak discharge with Routing and without Routing remains the same, however, only peak discharge tranlations occur and there is travel time. This happens because there is no debit data at the station being reviewed so it uses rain data instead of HEC-HMS modeling.

The most frequent problem that occurred in a box culvert is sedimentation. Sediments can be transported by changes in the water flow velocity, which can be influenced by changes of depth, h, of the channel bed. This research studies the change in h1 to h2 = 1,1 h1, 1,3 h1, 1,5 h1, 1,8 h1, and 2 h1, by simulation using SSIIM 1 program. The graph of the grain size distribution shows that the sediment consists of 99% of sands and 1% of silt, which its diameter of d50 = 0.8 mm and d90 = 4 mm. The discharge is 0.328 m3/s. The results, the deeper of the bed channel changes, the slower the flow velocity. The bed shear stress in changing the bed channel is smaller than the critical bed shear stress, and it makes the sediment stays. Based on the results, the variation of h2 = 1,1 h1, is preferred in sediment management.
