Many different types of embedded retaining wall are constructed due to the increasing demands. In Yangon, Myanmar is encountered deep excavation problem. Many buildings are damaged due to excavation of adjacent building. Therefore, embedded retaining wall as excavation support system is necessary to be sustainable buildings. There are important that influence of surcharge loading, retained soil and restrained soil on design of embedded retaining wall. In this paper, diaphragm Wall is emphasized and solved using soil structure interaction analysis. Behaviour of diaphragm Wall wall is based on various factors. Consider with natural and increasing of shear strength parameter of retained and restrained soils to get the level of the dredge line is stiff soil and various distances from wall to surcharge. Sites are located in urban setting, there are near building and separately from main structure. This project involves the construction of 5 m depth retaining wall. In case study (A) retained soils is soft, medium (low) clay, restrained soil is mostly cohesive soil. There are medium (low), stiff, medium, hard soil layers. In case studies (B to H) are increasing shear strength parameter of retained soil and restrained soil. All cases are considered with various distances from wall to surcharge. According to the soil conditions and distance from wall to surcharge, Wall depth, horizontal and vertical movement of ground and wall deflection are described. When retained and restrained soil reach stiff condition, then ground movement and wall deflection reach acceptable limit and wall depth become more safe and economical condition.

Monkasel monument is one of Surabaya's landmarks and will become "The Central Business District Riverbank". In this area has been built many recreational facilities, namely the statue of Suro and Boyo, Plaza Area, BMX Area, Tribune Area, Skate Park Area and Food court Ketabang. However, the development of water tourism in this area is still not optimal. One to overcome this is the need to develop a floating restaurant that can integrate all existing facilities, especially the food court. The development of this floating restaurant has multi-function, which is increasing the visitor of the food court, because this floating restaurant only provides a place to eat not sell food, as a place of business transactions and in the long run will improve the water quality of Kalimas river. This floating restaurant is designed with high comfort and safety, and environmentally friendly, so that all the functions can be accommodated well. This is because the floating diner is a catamaran boat that has a low sweep wave and uses solar panels

Publisher : Institut Teknologi Sepuluh Nopember

In this paper, we report a simple solution processed perovskite/polymer solar cell using CH3NH3PbI3 as an absorber, PCBM (6,6 phenyl C61-butyric acid methyl ester) as an electron transport layer, and PEDOT:PSS (poly (3,4-ethylene dioxy thiophene):poly(styrene sulfonate)) as a hole transport layer. The absorber solution was prepared by mixing of CH3NH3I (methyl ammonium iodide) with PbI2 (lead iodide) in DMF (dimethyl formamide) solvent. The absorber, electron transport, and hole transport layers are deposited by spin coating of the solutions. In order to obtain the optimum optical and electrical characteristics, the mixture of CH3NH3I and PbI2 are varied by the molar ratio of 1:1, 1:3, and 3:1, respectively. Because of CH3NH3PbI3 layer degrades, the fabricated cells have low performance. However, the cell using a molar ratio of 1:1 CH3NH3I and PbI2 gives the best electrical characteristics, results in an open circuit voltage of 0.04 V, a short circuit current density of 0.08 mA/cm2, and a power conversion efficiency of 0.002 %.

Indonesia lied among the three of world major plates so that several districts along the southern coast of Java Island were vulnerabled to the tsunami including Lumajang. South coast of Lumajang had high population density and settlements and high levels of government and economic activity. Therefore, it is necessary to know the level of insecurity and vulnerability to the tsunami in order to be utilized as input of mitigation data for the preparation of regional spatial plans (RTRW) based on tsunami risk level. The objective of this research is to arrange the regional risk map for tsunami in Lumajang Regency using Geographic Information System (GIS) through approach of insecurity and vulnerability analysis of tsunami. The insecurity rate is analyzed based on seismicity map and run-up data of tsunami event in Lumajang District. Vulnerability approach used multicriteria such as land elevation, slope, coastal morphometry, land use, distance from the coast and distance from the river. The methodology that was used included data collections of both primary and secondary data such as satellite imagery of earth map, Lumajang statistical data. Each vulnerability data variable was processed to result a weighting and scores that its become the parameters for making a regional tsunami vulnerability map. The results showed three level of risks in five subdistricts that directly adjacent to the Southern Coast such as Yosowilangun, Kunir, Tempeh, Pasirian, and Tempursari. The high tsunami risk which covered almost along the coast, the ramps morphology, without any protective vegetation and human activities at the site while the medium of tsunami risk which were in areas with elevation more higher than the coastal and the low of tsunami risk had variations of topography, quite far from the coast and less human activities.

In the research aims to analyzed feedback parameter on Self-Mixing Interferometry (SMI) signals. It is because the feedback parameter is one of the determined parameters in SMI vibration sensor research. The experimental apparatus consists of a laser diode as the light source, mirror as a target, collimator as light alignment, and PLX-DAQ as data acquisition executed by Arduino Uno. The principle of data retrieval with the manner of the light source is directed exactly perpendicular to the vibrating target, then reflected and arrested by the detector (photodiode) contained in the laser diode. Light arrested by the photodiode in the form of optical value then automatically converted into voltage value displayed on a personal computer (PC). This feedback on SMI is obtained by variation of the vibration frequency given to a target. The variation of vibration given is 10-100 Hz with 10 Hz increment and each frequency is taken 1000 data. Based on the research that has been done then results obtained at the frequency of 10-30 Hz feedback does not appear because the vibration small so that the vibration sensor is less than optimal. Feedbacks appear at frequencies 40 Hz and 50 Hz but are clearly visible at frequencies 50 Hz. While at 60-80 Hz frequency feedback begins to disappear. The existence of feedback on frequency 50 Hz indicated that vibration sensors on SMI can be applied to industry and medical field

Transportasi udara sebagai salah satu sub sektor transportasi yang termuda telah menunjukkan perkembangan yang demikian pesat. Kemajuan di bidang penerbangan telah merubah wajah dan peta perkembangan perekonomian, mobilitas penduduk, dan pembangunan secara luas. Untuk itu pembangunan bandar udara harus direncanakan kapasitasnya agar mampu melayani kegiatan penerbangan dalam jangka panjang, hal ini berarti melakukan perencanaan ke depan.Perencanaan pembangunan bandar udara idealnya berkapasitas besar, yang diharapkan mampu melayani kegiatan lalu lintas pergerakan pesawat udara dan penumpang yang cenderung meningkat cepat dalam jangka panjang, namun kendala yang dihadapi adalah dana pembangunan yang dibutuhkan terbatas jumlahnya dan ruang wilayah untuk pembangunan yang tersedia adalah terbatas. Meskipun terdapat keterbatasan, namun pelayanan kepada penumpang harus ditingkatkan kualitasnya. Untuk mengantisipasi pertumbuhan jumlah penumpang, pesawat dan kargo maka perlu diantisipasi pengembangan bandar udara dan fasilitas komersialnya dengan Konsep Pengembangan Airport City.Tujuan dari studi ini adalah : (1) mengidentifikasi faktor-faktor penting yang jadi isu utama dalam pengembangan Airport City secara umum dan Sultan Hasanuddin Airport City secara khusus, (2) Privatisasi dalam sub sektor transportasi udara/bandar udara telah dilakukan oleh banyak negara, tetapi mengapa di Indonesia belum satu pun bandar udara yang berhasil dalam penerapannya; bagaimana peluang, tantangan dan hambatannya, dan (3) untuk mendorong masuknya investor berinvestasi, faktor-faktor apa yang menjadi prasyarat dan langkah-langkah yang harus ditempuh.Formula yang digunakan dalam mengantisipasi lonjakan pertumbuhan jumlah penumpang, pesawat dan kargo adalah dengan menggunakan model regresi. Model batasan kawasan kebisingan (BKK) dan kawasan keselamatan operasi penerbangan (KKOP) digunakan dalam pengembangan bandar udara yang terintegrasi dengan tata ruang wilayahnya (pengembangan bandar udara menuju Airport City).Sebagai kata kunci dapat disebutkan bahwa: (1) dunia penerbangan dan bandar udara ke depan menjadi pusat pengembangan ekonomi dan bisnis yang kompetititf, (2) fasilitas komersial dengan cepat menghubungkan dengan pasar (markets), (4) perdagangan (air commerce) terhubung dengan airport city, dan (5) airport sebagai penggerak utama bisnis dan pengembangan kota di abad 21 ini (21st century).

Zingiberene oil (C15H24)) is one of diversification products which has a high level of economic values. However, the rate of export number toward the export number has just recently attained 0,3% . Moreover the number of ginger oil as the export product does not fulfill the export standart, such as the Essential Oil Association of USA (EOA). This condition happens since the Hydro Distillation is applied as one of the method in refining process. Nevertheless, this method is considered the best method in refining process although it takes more time to gain the result of the refining process. Another extraction process is called as Microwave Distillation and Simultaneous Solid-Phase Microextraction (MDSS-PM). By applying this method, the total time estimation is reduced significantly, but the final result in refining process is not as good as by applying Hydro Distillation. This research applies Microwave Distillation as the extraction process of white ginger. Furthermore, this kinds of method is modified in such a way by adding optical ultrasonic (MUSDf). The variable used in this research is Steam Diffusion (SDf), Microwave Extraction (ME), Microwave Steam Diffusion (MSDf), Microwave Ultrasonic Steam Diffusion (MUSDf). Moreover, this result takes 30, 50, 70, 90 and 110 minutes. Furthermore, the extraction temperature is 90, 95, 100 dan 105oC. The final research shows that MUSDf is considered the best method in extracting the ginger oil with the yield result about 0,952% and zingiberene 6,38%. Hence, the total price for each essential oil costs Rp 17.964 by gaining 100oC of the optimum extraction temperature.

It becomes more important to design energy-efficient for buildings. This is true in relationship to a public building design especially retail property such as traditional market. It calculates the use of energy during construction and operation. There are three alternatives for a building energy system which are passive energy, electrical equipment, and user processes. The alternatives are developed for a public commercial retail. They were selected by four stakeholders named government, tenant, designer, and property manager. It is not easy to make a decision where there are many stakeholders' interests. A decision support system is necessary. The system should support a collaborative process among decision makers. This paper presents a multi criteria and multi person decision process to develop agreement options and coalition formation to find the best fit option of the energy system for traditional markets building in urban areas. There are three stages involved in the process which are first is determining and scoring of every alternative for every stakeholder, second is determining the optimal solution (payoff optimum) for each stakeholder in a coalition, and third is analyzing the best fit options for every coalition and grand coalition. An analytical hierarchy process (AHP) based on satisfying option is applied for the first stage. A liner programming is used to determine payoff optimum in the stage two and an agent system based on game theory built the coalition algorithm on the stage three. The result shows a model of collaborative decision to select a building system at design process.
