Abstract

This research aims to determine the compressive strength and shear strength on clay which issubstituted with a mixture of sand variations. Soil tested in this study is derived from clay ofBelimbing Sari Village, Jabung District, East Lampung. This is done because if you set up astructure on top of the clay will cause some problems, among others, the small value ofcompressive strength and shear strength of the soil.To determine the effect of mixing clay with sand on the compressive strength and shear strength, itis done by varying the mixing of sand by 10%, 20%, 30%, 40%. From the test results it is obtainedthat the increase in shear strength to a maximum of 0.7534 kg / cm2 and a decrease in cohesionvalue of 0.10 kg / cm2 at mixing the sand as much as 40%. In the compressive strength reaches amaximum value at 30% of the mixing done 4 variation is equal to 0.4996 kg / cm3. The greater thelevel of sand were added then the lesser the value of the soil cohesion, friction angle and thecompressive strength will increase although the maximum compressive strength value in mixing30% sand.Keywords : Clay, Sand, Soil Compressive Strength, Soil Strength Press

Abstract

Penelitian ini dilakukan untuk memberikan informasi dan gambaran umum kepada masyarakat tentang air tanah yang ada dengan cara menginventarisasi, mengeksploitasi, mengeksplorasi dan konservasi air tanah di Kota Bandar Lampung. Studi ini menggunakan program Geographic Information System (GIS) yang didukung dengan data sekunder berupa peta Bandar Lampung, data air tanah serta data curah hujan. Dalam penelitian ini dilakukan digitasi terhadap peta yang terdiri dari peta kondisi eksisting Bandar Lampung yang selanjutnya dioverlay dengan titik lokasi sumur bor menggunakan program GIS. Selain proses digitasi, dilakukan pula analisa neraca air tanah yakni antara tinggi air pengambilan sumur bor dengan tinggi hujan yang terinfiltrasi. Hasil dari penelitian didapatkan nilai keseimbangan air di tiap zona infiltrasi pada tahun 2006 yakni untuk zona infiltrasi <1.10-2 cm/detik selisihnya sebesar 7,909 m/tahun, zona infiltrasi antara 1.10-2 - 2.10-2 cm/detik selisih 7,896 m/tahun dan zona infiltrasi > 2.10-2 cm/detik 7,881 m/tahun. Jika diasumsikan setiap tahun mengalami peningkatan jumlah sumur sebesar 10% maka pada tahun 2016, untuk zona infiltrasi <1.10-2 cm/detik selisihnya sebesar 7,896 m/tahun, zona infiltrasi antara 1.10-2 - 2.10-2 cm/detik selisih 7,863 m/tahun dan zona infiltrasi >2.10-2 m/detik 7,823 m/tahun. Dari hasil analisa tersebut bisa disimpulkan pada tahun 2016 air tanah masih mencukupi untuk kebutuhan Kota Bandar Lampung, namun jika di lanjutkan sampai tahun 2079 kemungkinan akan mengalami krisis air tanah.Kata kunci : air tanah, neraca air, Geographics Information System (GIS)

Abstract

AbstractSpecial Moment Resisting Frame System(SMRFS) is a system with the highest ductility and that has detail requirements in the calculation of structural reinforcement components of axial, bending and shear of beam and columns elements, as well as provisions regarding the beam column connection that will affect the overall performance building when receiving earthquake load. This study aims to determine the detail requirements of special moment resisting frame system in accordance with SNI 2847-2013 and performance evaluation of structures with pushover analysis. Based on study results, the level of structure performance in accordance with the performance point obtained shows that the values of the displacement target are 0.042 m in x-direction and 0.413 m in y-direction. The value of the performance point also shows that the building is designed in the Immediate Occupancy condition that is while the building receives the earthquake load, it is expected that the structure will not be damaged. Distribution of plastic hinge is appropriate to the expectation that is the strong column and the weak beam because plastic hinge formation begins from the beam element then the column element. From the pushover analysis, it is obtained the value of the actual reduction factors (R) are 8.9 in x-direction and 7.8 in y-direction, while the values of the actual system over strength factor (Ωo) are 4.34 in x-direction and 5.70 in y-direction and the values of actual deflection magnification factor (Rd) are 5.9 in x-direction and 5.2 in y-direction.Keywords : pavement distress types, severity level, PCIAbstrakSistem Rangka Pemikul Momen Khusus (SRPMK) merupakan sistem dengan daktilitas tertinggi dan memiliki persyaratan yang detail dalam perhitungan penulangan komponen struktur aksial, lentur dan geser untuk elemen balok dan kolom, serta ketentuan mengenai hubungan balok kolom yang akan mempengaruhi kinerja bangunan secara keseluruhan ketika menerima beban gempa.

Abstract

 Shearwall is one of alternative solution in planning of building structure for earthquake-resistant. Shearwall is able to affect stiffness of the building structure and provide a structure with good ductility, so as to minimize the damaged caused by earthquake shaking. This study aimed  to analyze the positioning of shearwall on a building structure models using non-linear static analysis (Pushover)   In the analisys, shearwalls on each models are placed at different position. The performance of the building structure was analyzed using SAP2000 program. The result of the analysis is a form of drift ratio on each model of the buliding structure. From the result obtained drift value ratio on  without shearwall model, model 1, model 2, model 3, model 4, model 5, model 6 in the X direction in sequences as follows: 54 x 10-8; 48 x 10-8; 42 x 10-8; 30 x 10-8; 28 x 10-8; 8 x 10-9; 8 x 10-9 . While in the Y direction as follows: 77 x 10-5; 66 x 10-5; 62 x 10-5; 51 x 10-5; 23 x 10-5; 15 x 10-5; 14 x 10-5. So we can conclude that model 6 has better performance compared to other models.

Abstract

The growing population and the increasing economic growth in the city of Bandar Lampung haveled to expanding geographic mobility within the city. The provision of a mass transit system,therefore, is vastly indispensable for anticipating high traffic densities. This study was trying toexamine whether the operational performance of trans-Bandar Lampung buses, or called “BusRapid Transit” (BRT), has conformed to the existing standards. The results are expected to betaken for consideration by the municipal government when adopting policies to improve BRT’soperational performance and to scale back traffic jams.The study focused only on one corridor, the Rajabasa-Sukaraja corridor, and used the World Bank(1986) standards as the reference. Observations were then made in three days: Monday andThursday to represent workdays, and Sunday to represent days off, with each observation dayspanning from 6.00 a.m. to 6.00 p.m.The results reveal that time headway, 6.29 minutes (on the Rajabasa-Sukaraja corridor), and tripspeed, 25.45 km/h, have met the World Bank’s standards. However, traveled distance, 112.36 kmper vehicle, and load factor, 20.53%, are below the given standards. This low load factor has led tosmall revenue per vehicle, i.e. only Rp346,503.56. Dividing the amount by the operating cost(operating ratio) per vehicle gives us a value of 0.7 (less than 1). In other words, the BRT systemhas been operating at a loss.In the final analysis, it is vital that the municipal government take strategic policies to reduce thenumber of minibuses, or angkot, that operates on the same corridor as the BRT buses’, so thatmore passengers will shift to these BRT buses. The government should also grant subsidiesimmediately to make up for the loss currently being suffered by this BRT.Keyword : BRT, trans-Bandar Lampung bus, Rajabasa, Sukaraja, time headway, load factor.
