Abstract

Indonesia's geological condition has earthquake potential that covers most of its territory. To reduce the risk of disaster, it needs earthquake resistant building construction. Generally in existing calculations, the calculation of earthquake loading that is assigned to the ETABS program or SAP 2000 is the result of manual data input and placed at the center of each floor by assuming the upper and lower structure (foundation) are separate. In fact, the structure and the ground (foundation) become a unity.The study was conducted by analyzing the magnitude of the reaction due to conventional analysis to be equivalent to spring by taking into account the amount of the support settlement.The results of the study showed that the momentary support of the exterior beam interaction analysis (spring) decreased for all floors. While in the field moment the beam of interaction analysis (spring) increased, and at the moment of the pedestal beam interior interaction analysis (spring) increased. Keywords : Consolidation, Impact of earthquake loads on soil, immediate settlement.

Abstract

Indonesia  merupakan  negara dalam  masa  berkembang  pembangunannya  dimana prasaranayang dibangun tidak lepas dari tanah bidang miring atau lereng, seperti pembangunan perumahan dan pembuatan Embankment untuk jalan Tol. Menyikapi kejadian ini penulis melakukan analisa stabilitas lereng dengan dan tanpa perkuatan melalui pemodelan di laboratorium. Ada beberapa jenis perkuatan tanah, salah satunya menggunakan perkuatan Geotextile,   penggunaan  Geotextile  dapat  meningkatkan  stabilitas  lereng.  Penelitian  ini bertujuan untuk mengetahui stabilitas lereng terhadap pengaruh tiga variasi jarak pembebanan pondasi dangkal dan tiga variasi kemiringan lereng. Pengujian dalam penelitian ini dibedakan menjadi  2  macam  model  yaitu:  (1)  Pengujian  Model  I  merupakan  uji  2  variasi  jarak pembebanan dan 3 variasi kemiringan tanah tanpa menggunakan perkuatan Gotextile Woven (2) Pengujian Model II merupakan uji 2 variasi jarak pembebanan dan 3 variasi kemiringan tanah dengan menggunakan perkuatan Gotextile Woven. Di tinjauan dari 3 (tiga) variasi kemiringan, yaitu: 45º, 50º, dan 60º serta 2 (dua) variasi jarak beban yang bekerja pada lereng, yaitu: 4 cm dan 7 cm. Pada pemodelan tanah sebelum diperbaiki menggunakan Geotextile dapat diketahui bahwa semakin kecil sudut kelerengannya, maka daya dukung tanah yang dikorelasikan dengan kekakuan tanah bernilai besar. Sedangkan pada pemodelan tanah sesudah diperbaiki menggunakan Geotextile semakin kecil sudut kelerengannya, maka daya dukung tanah yang dikorelasikan dengan kekakuan tanah bernilai kecil. Pada pemodelan tanah sebelum diperbaiki menggunakan Geotextile dapat diketahui bahwa semakin jauh jarak pembebanan dari bibir lereng, maka daya dukung tanah yang dikorelasikan dengan kekakuan tanah bernilai besar. Sedangkan pada pemodelan tanah sesudah diperbaiki menggunakan Geotextile semakin jauh jarak pembebanan dari bibir lereng, maka daya dukung tanah yang dikorelasikan dengan kekakuan  tanah  bernilai  kecil.  Dapat  di analogikan  bahwa perbaikan tanah  lereng dengan menggunakan Geotextile mempunyai sifat memperkaku tanah yang mana semakin besar sudut kelerengan maka semakin kaku.

Abstract

Indonesia is a country in a period of growing development where the infrastructure is built not off of the ground inclined plane or slope, such as housing construction and the manufacture of the Embankment to the road Toll. Responding to the incident the author conducted the analysis of stability of slopes with and without reinforcement through modeling in the laboratory. There are several types of soil reinforcement, use reinforcement Geotextile, the use of a Geotextile can increase the stability of the slope. This study aims to determine the stability of the slopes against the influence of the three variations of the distance of loading a shallow foundation and three variations of the slope. Testing in this study are divided into 2 kinds of models, namely: (1) Testing the Model I is test 2 variations of the distance of loading and 3 variations of the slope of the ground without the use of reinforcement Gotextile Woven (2) Testing the Model II is a test of the 2 variations of the distance of loading and 3 variations of the slope of the land with the use of reinforcement Gotextile Woven. In a review of 3 (three) variations of the slope, namely: 45º, 50º, and 60º, as well as 2 (two) variations of the distance of the load acting on the slope, namely: 4 cm and 7 cm. On the modeling of the soil before repaired using Geotextile can be seen that the smaller the angle kelerengannya, then the power capacity of the soil is correlated with soil stiffness is of great value. While the modeling of soil after repaired using Geotextile the smaller the angle kelerengannya, then the power capacity of the soil is correlated with the stiffness of the soil of little value. On the modeling of the soil before repaired using Geotextile can be seen that the farther the distance of loading from the lips of the slopes, then the power capacity of the soil is correlated with soil stiffness is of great value. While the modeling of soil after repaired using Geotextile the greater the distance of loading from the lips of the slopes, then the power capacity of the soil is correlated with the stiffness of the soil of little value. Can in the analogy that the repair of soil slopes using Geotextile has the properties memperkaku the land where the greater the angle of the slope then the more rigid.

Abstract

Pemerintah  Provinsi  Jawa  Timur  berupaya  membangun  jaringan  jalan  baru  berupa  JalanLingkar Luar Barat Surabaya (JLLB) yang memiliki panjang ± 19,8 km dengan lebar 55 meter. Diharapkan untuk memecah kemacetan di pusat kota Surabaya dalam rangka memfasilitasi akses penduduk dan meningkatkan pertumbuhan ekonomi. Kondisi tanah di lokasi ini adalah tanah lempung lunak yang mencapai kedalaman 21 meter, Tanah lunak itu sendiri memiliki sifat yang tidak menguntungkan secara teknis untuk mendukung pekerjaan konstruksi. Secara umum  tanah  lunak  memiliki  kapasitansi  rendah,  permeabilitas rendah  dan  kompresibilitas tinggi menyebabkan tanah ini mengalami penurunan yang sangat besar dan membutuhkan waktu yang lama. Salah satu alternatif perbaikan tanah untuk mengatasi masalah ini adalah kombinasi metode preloading dengan drain vertikal yang dibuat sebelumnya. Metode ini dilakukan dengan membebani tanah dengan beban awal lebih besar dari atau sama dengan beban bangunan yang direncanakan. Penelitian ini bertujuan untuk mempercepat proses konsolidasi tanah untuk meningkatkan daya dukung tanah sehingga pembangunan jalan menggunakan timbunan dapat dilakukan dan menganalisis efisiensi rencana anggaran.

Abstract

The construction of the Probolinggo-Pasuruan toll road has resulted in faster travel times along the Jember-Surabaya route. However, it has been observed that economy buses rarely use the toll road. To determine the likelihood of passengers switching between economy-class train and economy-class bus modes, a study on the selection of economy-seat modes between the cities of Jember and Surabaya is necessary. The study utilized the Stated Preference method for data collection, which involved distributing questionnaires to passengers at stations and terminals. The data collected were analyzed using the binomial difference method. The results of the study reveal that the Economy-Class Train mode is the most preferred mode of transportation. Experimentation on the travel cost attribute (ΔX1) with the value of Uka-Ubu Utility = 6.512 - 0.0887(X1) + 0.292(X2) revealed that 99% of passengers chose the train. On the travel cost attribute (ΔX1) with the value of Uka-Ubu Utility = 0.0205 - 0.0034 X1, 55.2% of passengers chose the train. Meanwhile, on the travel time attribute (ΔX2) with the value of Uka-Ubu Utility = 0.0202 - 0.0034 X2, 52.6% of passengers chose the train.

Abstract

The foundation is a building structure located under the building. The foundation cannot be separated from the building structure because it is a structural part whose function is to transmit the load from the upper structure to the supporting soil layer beneath it to prevent collapse of the soil or settlement of the structural system. This research compares the costs and time required for pit foundation work with site foundations, with the aim of finding out whether the planned costs and implementation time have the same efficiency or not. The purpose of this research is to find out how much bearing capacity there is in the well and site foundations, how much costs are needed to plan the well and site foundations, and how long the implementation time is required. The method used in this research is a comparative study (Comparison). The comparative or comparison method is research that uses the technique of comparing an object with another object. The objects being compared, the comparative method is carried out to compare the similarities and differences of two or more facts and properties of the object being studied. From the calculation analysis, the bearing capacity of the well foundation was obtained at 1950 KN with a cost of IDR 469,046,724 and an implementation time of 78 days. Meanwhile, for the site foundation, the foundation bearing capacity was obtained at 451.11 KN at a cost of IDR 174,598,298 and a construction time of 56 days.

Abstract

The Tahfidzul Qur'an Bambu Kuning girls' dormitory is an Islamic boarding school-based educational foundation located in Tanggul Kulon Village, Tanggul District, Jember Regency. The maximum number of dormitory residents uses calculations of the space capacity in the building and the development plan for the Islamic boarding school. Based on this approach, the maximum number of boarding school residents is 320 people. So if the occupants meet the maximum capacity, the waste that will be produced is 61.44 m3/day. The handling of domestic waste (blackwater and greywater) at the Tahfidzul Qur'an Bambu Kuning girls' dormitory is still processed using a septic tank which directly absorbs into the ground and there has been no draining activity so far. This has the potential for environmental pollution, which causes the potential to increase. suffer from disease. Therefore, it is necessary to make efforts to improve sanitation, namely planning a domestic wastewater treatment plant with an Anaerobic Baffled Reactor (ABR). The planned ABR has 3 compartments with total dimensions of length, width and depth of 12.3 meters, 6.12 meters and 2.5 meters. Construction with the ABR unit produces low concentrations of BOD, COD, TSS, oil and fat, and total coliform, respectively 6.82 mg/L, 17.5 mg/L, 7.87 mg/L, 1.46 mg/ L, and 300 mg/L which meets the quality standards set by the Minister of Environment and Forestry Regulation No. 68 of 2016 concerning domestic wastewater quality.
