Abstract

Kerusakan jalan sering terjadi karena kondisi tanah yang kurang mendukung dan arus lalu lintas yang cukup padat. Pada proyek penelitian ini, bila dilihat pada kondisi awal jalan yang merupakan jalan lapis permukaan HRS-Wc sudah mulai rusak/kasar dan  dibeberapa tempat terlihat permukaan yang bergelombang atau berlubang. Perkerasan kaku diambil berdasarkan kondisi lingkungan sekitarnya dan umur rencana yang relatif panjang. Walaupun bila dilihat dari segi biaya awal, perkerasan ini mempunyai biaya awal yang relatif tinggi bila dibandingkan perkerasan lentur. Metode yang digunakan pada penelitian ini adalah analisis biaya menggunakan analisa deret seragam/ annual worth adalah semua aliran kas yang terjadi selama horizon perencanaan dikonversikan kedalam deret seragam dengan tingkat bunga sebesar MAAR. Hasil yang didapat adalah perkerasan Kaku lebih ekonomis bila dibandingkan dengan Perkerasan Lentur. Pada perkerasan kaku didapatkan biaya sebesar Rp. 142.232/ m2, sedangkan pada perkerasan lentur didapat biaya yang lebih kecil yaitu Rp.184.471,-/ m2. Perkerasan kaku lebih ekonomis karena mempunyai ongkos yang lebih kecil.

Abstract

Problema utama pembangunan infrastruktur transportasi pada tanah lempung lunak (soft clay) adalah daya dukung tanah dasarnya yang relatif rendah dan pemampatan tanah dasarnya yang relatif besar serta berlangsung relatif lama. Apabila tanpa  dilakukan perbaikan pada  tanah dasarnya  terlebih dahulu  maka  infrastruktur transportasi yang dibangun berpotensi akan mengalami kerusakan sebelum mencapai umur yang direncanakan. Untuk menanggulangi problema tersebut salah satu dari beberapa alternatif yang bisa dilakukan adalah melakukan perbaikan tanah dasar metoda preloading dengan penggunaan prefabricated vertical drain (PVD). Makalah ini menguraikan prinsip- prinsip dasar perbaikan tanah lempung lunak metoda preloading dengan penggunaan PVD dan beberapa contoh aplikasinya pada pembangunan infrastruktur transportasi di  Pulau Kalimantan. Diberikan juga contoh aplikasi perbaikan tanah lempung lunak metoda preloading dengan penggunaan PVD yang menerapkan sistem kontrak berbasis kinerja (performance based contract).

Abstract

Thermosypon are heat exchangers in the form of a pipe that consists of three main parts: evaporator (the bottom of the tube), adiabatic and condenser (top tube). Evaporator part is the part that receives heat and absorb them to be brought goto the condenser, the part which releases heat to the environment. Among the evaporator and condenser there is a section that separates, ie adiabatic section as part of an isolated so no temperature exchange with the pipe lingkungan.Didalam there is the working fluid that carries heat from the evaporator evaporator.Panas absorbed from the environment and move up the tube because of differences in density between the vapor and liquid to kesisi condensation (condenser) and heat dilepaskan.Pada side vapor condensation condensed into liquid and moves down back to the evaporator because of the force of gravity.In this study, thermosypon made of copper with a diameter of 12,7 mm and a length of 500 mm with a length of 195 mm condenser. The area subject to the evaporator as the heat source side, adiabatic section is isolated so that no heat exchange with the environment and the area condenser mounted heat sink which aims to remove heat from the heat pipe to the environment. The research was done by varying the concentration of the working fluid, the concentration of the mixture of acetone and ethanol.Variasi fluid mixture concentrations used in this study is the percentage of acetone to methanol, yaitu0%, 20%, 40%, 60%, 80% and 100%. The data required is the temperature at the evaporator (Te), the temperature of the condenser (TK1, Tk2, TK3) and air temperature (Tu).The results showed that, most small thermal prisoner at the time of the concentration of 100% acetone to ethanol. At the same acetone concentration, the higher the power (the higher the temperature), the greater the heat flux and power output. The process in this experiment the largest output power and capacity terbesarterjadi the acetone concentration of 100% and the highest power (63 W).

Abstract

The progress of science and technology from time to time is growing rapidly. Iftraced back, first all activities are done manually. Along with technologicaldevelopments, some activities have been converted into an automated system.Like to open a door that requires human labor, now has many doors that can beautomatically opened when there is someone who will enter. But there are fewobstacles, whereas when someone is running quickly it must wait for the door toopen automatically which causes the person to stop first and wait for the door toopen. In this Final Project, ultrasonic sensor (PING) is used to measure visitordistance. Dc motor is used to set the speed of opening the door. The prototype ofautomatic sliding door is controlled using arduino microcontroller. Test resultsshow that the door will open when visitors are in front of the door measured withultrasonic sensor (PING). After the tool testing, the maximum load of the doorthat can be moved by the tool is less than 15 kg. The time it takes the automaticsliding door to close with the maximum load is 3.12 seconds.

Abstract

Cooling is an important activity in maintaining a large temperature of a component, both mechanical components and electronic components. Component temperature which is maintained from overheating will avoid damage. The cooling process is carried out by moving the heat produced by a component through a heat exchanger. One effective heat exchanger is Thermosyphon. This tool is able to move a number of heat through a very small surface area. Thermosyphon is a pipe that contains a working fluid, consisting of three parts, namely the evaporator section, the adiabatic section and the condenser section. The evaporator has the function of absorbing heat from the heat source and heat is released in the condenser. The process of heat absorption and release of heat is carried out by the working fluid in the pipe, when the fluid is in the heated evaporator it will evaporate towards the condenser the heat is released. The fluid which is finally from the condenser returns to the evaporator. This study aims to determine the thermal performance of the thermosyphon as a heat exchanger with condenser length variations. Thermosyphon is designed with a condenser length variation of 44 cm, 66 cm, 88 cm, 110 cm and 132 cm running with variation temperature. The results showed that, the highest thermal resistance at the shortest condenser length at 400C (140C / W) and the lowest at the longest condenser length at 1200C (10C / W). At all temperatures, all variations in the length of the condenser will increase the output power and heat flux. At the same condenser length, the higher the temperature, the greater the heat flux and output power. The process of this experiment is most effective at the length of the condenser 1.25 (132 cm) from the length of the evaporator length, because after that the value of thermal resistance and output power will experience a permanent tendency.

Abstract

The problem in Energy conservation is finding new opportunities for high-efficiency energy generation including wind power generating machines. Aims of this study to determine the effects of blade number and curv angle of blade mounting on the output power of a Savonius type wind turbine. This low speed wind turbine is intended to get energy at the top of a multi-storey building in an urban area. Tests were carried out on a laboratory scale, using savonius wind turbines with 400 mm diameter and 500 mm height. The driving wind speed of the turbine is set between 1.5 to 8.5 m / s. While the number of blades used is 2 types, namely rotor with three blades and rotor with 4 blades, each of which is tested on 3 different types of curv angle blade. The investigation results are expected to show that the wind tubing from each experiment will give different characteristics. This investigation results that there was increasing in efficiency in the savonius turbine with blades. The highest rotation and power occur when the turbine uses 2 blades and -50 curv angle of blade mounting
