The rapid development of communication technology in wireless communication has led to an increase in technologies related to wireless communication. The WLAN (Wireless Local Area Network) network is one example of a network that continues to experience developments in the wireless communication technology. One of the WLAN network configurations is an ad hoc network. Different protocols, data transmission in an ad hoc WLAN will also experience differences in performance. This final project examines the use of three (2) transport protocols, namely TCP and UDP with their use in WLAN with ad hoc networks and the encryption decryption process to determine the percentage comparison of the success of packet delivery. To analyze the comparison of the three transport protocols on an ad hoc network, the Network Simulator 2 (NS-2) application which is integrated into the Ubuntu operating system and algorithms used such as arcfour, rijndael-192 and tripledes is used. The results showed that the percentage of successful data transmission on TCP was greater with an average of 99.318% on the arcfour algorithm, 99.185% on the rijndael-192 algorithm, 99.132% on the tripledes algorithm. While the percentage of success in sending data on UDP is smaller with an average of 70.711% on the arcfour algorithm, 63.971% on the rijndael-192 algorithm, 64.412% on the tripledes algorithm.

Steel is one of the most widely used construction materials. Along with the development of technology in the field of construction, many variations have been made in the use of steel as a construction material to make it more suitable for the needs and economical in terms of cost. One of the innovations that is often used in steel is to make holes in the body to increase the height of the steel profile. The shape of the hole that is usually formed on the body varies. The most frequently used variations are the hexagon shape (honeycomb beam) and the circular beam (cellular beam). In this study, we will compare the honeycomb beam and the cellular beam. The two beams will be made in several variations with D/Do and S/Do parameters. The experiment was carried out using the ANSYS program. Comparisons are made to find a beam that has a better ability than the parameter variations on the two beams From the results of the study, it was found that the best parameter variations were D/Do = 1.6 and S/Do = 1.08 for honeycomb beam. For cellular beam D/Do = 1.6 and S/Do = 1.28 which is better. Then from the comparison of cellular beam and honeycomb beam, it is found that the honeycomb beam is better.

Photovoltaic is a semiconductor device that utilizes photon energy from the sun to be converted into electrical energy. The electrical energy produced by photovoltaic is optimized by a system called Maximum Power Point Tracking (MPPT). MPPT will find the optimal working point of the photovoltaic and keep it always working at that point. In this study, the methods used to find the optimal work point are Incremental Conductance and Perturb and Observe. MPPT is connected to the Boost Converter as a photovoltaic voltage controller. The analysis of the two MPPT methods was carried out through simulation in MATLAB/Simulink. The photovoltaic model is designed with reference to the KS80M-36 photovoltaic model. The MPPT system that has been designed is then simulated and its performance is seen. The MPPT system that has been designed using the Incremental Conductance algorithm and the Perturb and Observe algorithm has succeeded in finding the optimal photovoltaic working point and is able to respond to changes in environmental conditions by finding new optimal working points. The two MPPT systems are also able to make photovoltaic work at that optimal point. The Incremental Conductance algorithm has a power ratio of 96%, while the Perturb and Observe algorithm has a power ratio of 95.4%.

Along with the development of the construction world, the need for concrete is increasing and the scale of development shows that there will also be more and more concrete needs in the future, thus affecting the development of concrete technology which will demand new innovations regarding the concrete itself. In the construction of high-rise buildings required concrete with high compressive strength. However, to get good quality concrete, high costs are also required. So in this study, an economical additional material will be used which will be added to the concrete in the form of latex and hair fiber. Testing of materials and test objects is carried out in accordance with the applicable Indonesian National Standard (SNI). The latex used is liquid latex. First, the hair fiber is washed in order to clean the dirt and debris attached and then dried in the sun for 2 days, then cut to a size of ± 30 mm. By adding latex with variations of 0.25%, 0.5% and 0.75% it is expected to achieve a concrete quality of 20 MPa and by adding 2% hair fiber and latex with variations of 0.25%, 0.5% and 0.75% is expected to achieve a concrete quality of 20 MPa. The research object used a cylinder with a diameter of 15 cm and a height of 30 cm with the addition of 48 pieces of latex which were tested at the age of 28 days, cylinder with a diameter of 15 cm and a height of 30 cm with the addition of latex and hair fiber as many as 18 pieces were tested at the age of 7 days, and a beam without reinforcement with a length of 60 cm, width 15 cm and height of 15 cm with the addition of latex and hair fiber as much as 3 pieces The Water Cement Factor (FAS) in this study was locked at 0.5. This study was intended to obtain the value of compressive strength, split tensile strength, concrete absorption, slump value in cylinders and flexural strength values in unreinforced beams. From the test results, it was found that the slump value decreased due to the addition of the latex additive and increased due to the addition of the latex and hair fiber additives and then increased along with the increase in the additional variation. The absorption of concrete also decreased with the addition of the latex additive and increased with the addition of the latex additive and hair fiber. The most optimum compressive strength results were obtained in concrete with the addition of 0.75% latex variation, an increase of 13.226% from normal concrete while the most optimum compressive strength results were obtained in concrete with the addition of 0.75% latex variation and 2% hair fiber reduced by 0.94% from normal concrete.

As buton product that is currently being developed is Asbuton type BGA or called Buton Granular Asphalt which has bitumen content between 20-25% (Puslitbang Prasarana Transport Dep.PU, 2005). BGA has been used in several locations but its use is considered not optimal, therefore the authors want to examine how the effect of variations in the level of addition of asbuton material on the performance of asphalt mixtures. In this study, testing was carried out in stages, starting with material testing consisting of aggregate testing (coarse, fine, filler), as well as asphalt property testing and BGA material testing. Then a mixture of Marshall test objects will be made to be tested. The mixed test method used is the Marshall method which will then produce parameter values in the form of VFB (Void Filled Bitumen), Stability, Residual Stability, VIM (Void in Mix), VMA (Void Mineral Aggregate), flow, and MQ (Marshall Quotionent). The purpose of this study was to determine the effect of adding variations in the use of BGA type 5/20 materials, namely 0%, 3% and 5% on Marshall characteristics of AC-WC hot asphalt mixture using the 2010 Binamarga Specification Revision 3. The results showed that the addition of Asbuton Item 5/20 significantly increased the value of stability, residual stability and MQ along with increasing levels of asbuton used, but did not significantly affect the value of VMA, VFB and Flow and concluded that the use of Asbuton BGA with a level of 3% has produced optimal results.

Worldwide Interoperability for Microwave Access (WiMAX) is a Broadband Wireless Access (BWA) technology that has high speed and wide access for multimedia communication. The reception of quality video or voice packets at the receiver is related to how efficient the energy consumption is sent by the Subscriber Station (SS). The more video or voice packets that are sent, the more energy consumption is needed. One way to calculate energy consumption at a WiMAX subscriber station is by using mathematical modeling. This final project is modeling energy consumption in WiMAX. From the simulation, it is found that the change in the bit rate affects the energy consumption of the subscriber station. Through simulation, training data is generated to obtain a mathematical model.The mathematical model contains the components of the state duration and the level of energy consumption. Mathematical models are then used to predict energy consumption in WiMAX. The model is tested through the generation of test data. The test results through simulation showthe percentage deviation of the average energy consumption of training data with mathematical modeling on average is 0.180%. Meanwhile, the energy consumption of test data and mathematical models has an average deviation of 0.187% and 0.191%. The least energy consumption is generated when the MAC Initialization state (state i0) is 0.001 Joule, while the highest energy consumption is the Uplink Frame state (state i14) of 101.017226 Joule.

Almost 70% of the energy produced by the generator is consumed by electric motors. The use of induction motors in industry and factories is more profitable than DC or synchronous motors, one of the advantages is easy maintenance and high efficiency. On machines in the industry speed regulation is absolutely necessary. Along with the development of power electronics, this has become very easy to do, namely by supplying a motor with a variable speed drive (VSD) inverter. With the supply of a variable speed drive inverter, it is possible to adjust the motor speed by adjusting the voltage frequency.This study was conducted to determine the effect of decreasing the frequency using a variable speed drive inverter on the performance of a five-phase induction motor. Tests are carried out at a frequency of 50 Hz (grid frequency), 35, 40, 45, 50 Hz (inverter frequency) and the motor is loaded at 0.5, 1, 1.5, 2, 2.5Nm. From the research, it was concluded that, among others, the use of a variable speed drive inverter resulted in greater motor losses and the motor produced a louder sound. At the same frequency (50 Hz) the efficiency of the motor is better when supplied directly from the grid.

Steel scaffolding is a very important component in formwork work to support further work. The purpose of this analysis is to review the maximum compressive strength that occurs in 3-story scaffolding before buckling occurs using the direct analysis method (DAM). The design of steel structures, which are generally slender, requires stability analysis. The result is influenced by imperfections (non-linear geometry) and inelastic conditions (non-linear material). In this final project, we use second-order inelastic analysis based on direct analysis method. The 3-level scaffolding model was analyzed using beam elements in the SAP2000 program with 6 variations of notional loads applied to the weak axis direction of the scaffolding pipe.The lowest compressive strength on 3-story scaffolding before buckling occurs is 18.24 kN with horizontal notional loads to the right on the first level scaffolding, left on the second level scaffolding and to the right on the 3rd level scaffolding. The results of the analysis show that the maximum compressive strength obtained results in a large displacement drastically in the iteration step. By using the analysis on the DAM method, the results obtained are more effective.
