Penyelesaian Jalur Terpendek dengan menggunakan Algoritma Maze Mapping Pada Line Maze
No full textPada umumnya algoritma maze digunakan untuk mencari jalan keluar pada jaringan jalan yang terbentuk atas lorong-lorong yang dibatasi oleh dinding tanpa atas yang biasa dibuat labirin. Pada line maze, jaringan jalan yang terbentuk dibuat dengan menggunakan garis. Jika garis berwarna putih maka background berwarna hitam atau sebaliknya. Permasalahan yang timbul pada line maze adalah cara untuk mendapatkan jalur terpendek dari line maze. Pada paper ini, permasalahan pada line maze diselesaikan dengan algoritma maze mapping. Algoritma ini terdiri dari dua mode, yaitu mode search dan mode return. Pada mode search, robot melakukan perjalanan dari posisi start menuju finish dengan aturan bahwa robot akan mengutamakan belok kiri bila menjumpai persimpangan. Kode-kode unik dibangkitkan setiap robot berjumpa dengan persimpangan. Pada mode return, robot sudah berjalan dari start menuju finish dengan jalur tependeknya. Jalur terpendek diperoleh dari kode-kode unik yang telah dikonversi. Berdasarkan percobaan program konversi yang telah dilakukan, maka dibutuhkan formulasi yang handal agar diperoleh hasil yang diinginkan. Pada pengujian keseluruhan sistem, diperoleh error sebesar 10% dari 10 kali percobaan berturut-turut. Kata kunci— robot, maze, mapping, PID, sensor garis

Pemanfaatan Energi Matahari Sebagai Backup Energi Listrik Pada Beban Rumah Tangga 450 VA
No full textThis time enlarge of electric power is needed but supply of electric power is too limit. To solve this problem so are needed alternatives energy. Like a solar energy to change the unrenewable energy. To use the solar energy are needed solar cell to change from solar energy to electric powers. The electric powers are produced by a solar cell with 50 WP until ± 19,1 volt and the max current that flow of its are about 1,67 ampere. After that, the electrical powers save in battery and the Voltage output of this battery are raised by boost converter until 175 volt as Voltage input of the inverter. The inverter changes from DC voltage of this to AC voltage 125 volt and this electric power ready to supply the household device. Keyword: solar cell, boost converter, inverter

No full textIn one of the processing water treatment,there is process which name is filtering process. Filtering is used to filters and clean water, for that reason, filter necessary washed. With method that used now, washing filter by side PDAM with scheduling method obvious not optimal and efficient. But with turbidity and water level of reservoir parameter, PDAM is getting optimation in using electricity power energy. Qualiity of water is guaranted and quantity of water distribution is also permanent awake. augmenting with system SCADA also reachable especially during efficiency and data registration or data logging.

PROTOTYPE SISTEM PENGENDALIAN KUALITAS LEVEL ISI PADA PRODUK MINUMAN KEMASAN DALAM BOTOL
No full textBottled beverage industry is currently growing many types and variety. Beverage products packaged in bottles are filled through the machine automatically. However, in reality still often found that the filling machine is unable to fill in the exact same volume. This may occur because of damage to the valve system or the electrical voltage fluctuations or human error. Therefore, companies need to use a quality control system so that the volume filling of bottles as same as with each other The final project is designed and manufactured a machine controller in the filling level of quality beverage products packaged in bottles using a digital microscope. Where parameter is the height of the surface-controlled beverages in bottles. Through this filling level can be known volume of beverage in the bottle so that it can be calculated quality characteristics [2] [5]. Bottles filled with bottles of good will to go to the place prepared and ready to marketed. Whereas bottle that is not fully filled will be sorted or moved to another conveyor for improved volume. The manufacture of hardware such as mechanical conveyors are equipped with a digital microscope, the surface height measurements using image processing method beverages [1], [4] through the use of the digital microscope. While microcontroller ATmega16 [3] as a control would make the process of reading data by comparing the appropriate data and not in accordance with the data is already standard (used as parameters). From the resuls of measurement at 06.00, 11.00, 16.00 is got as same as error score measurements (mean percentage error measurements 2.48%, 1.78%, 2.42% ). And if a measurements to other bottle drinks which the colour are transparent (bottle drink as same as colour with bottle) are got more error value measurements 3.96%.

Rancang Bangun DC Power Supply Dari Sumber 3 Phasa Untuk Perbaikan Power Faktor dan Menurunkan THD Menggunakan Fullwave Rectifier Dengan Metode Switching PID-Fuzzy Pada Boost Konverter
No full textThree phase fullwave rectifier is one of changes technique from 3 phase Ac voltage to Dc voltage. Rectification process by diode, caused phase shifting of current to voltage and also affected in occuring harmonic in input side, so power factor is generated arround 0.6 and Thdi 17.5 %. With boost converter circuit which it switching use PID Fuzzy method,the input power factor is arround 0.86 and THDi 41.47% for 100W lamp, and also with 200W lamp the power factor is arround 0.86 with THDi 50.03%. To reduce THDi quantity,EMI filter circuit is used in input side so the final result of THDi is arround 24.15% with 0.89 power factor for 100W lamp. For 200W lamp THDi is arround 26,15% with 0,89 power factor. Keyword : 3 Phase fullwave rectifier, THDi, Power Factor, Boost Converter, EMI Filte
RANCANG BANGUN PENGONTROL TIRAI OTOMATIS VIA SMS
No full textTo make human life easier is all people‟s dream. It is acceptable, because in this era all people is busy. Busy with all their activities and works, but there is a things that they must leave to complete their activities or works. From eating, sleeping or resting, praying, or another activities like sport, vacation, clening their home, even a little thing like open the curtain must they leave for their job. There is alot kind and size of curtain, from small one usually in people‟s home, the middle one often for the cover of plants, or the big one is usually in the movies or theatre. There many of them is handled by human hands and not autumatically, except the movies and theatre curtain, it‟s electrically with button. But not all movies and theatre have this tools. So with this final project hopelly can solve that problem. This curtain is can handled by cellphone or button. The process will begin with sending SMS to the server cellphone, from there the micro will take over the process. The micro will send data to the driver and make the DC motor running. So, the curtain will be open or closed

No full textSome emphysema can influence lung capacities and volume, for example asthma or emphysema that happened by effect of decreasing air stream that enter to the lung. Respiration Signal can be used to know lung capacities and volume. Therefore, at this final project designed an appliance to know lung capacities and volume by using breeze appliance provided with MPX5100 strain gauge sensor. Strain gauge with MPX5100 series representing sensitive pressure sensor to low pressure, only with puff can influence voltage of output yielded. Change of yielded voltage will be strengthened with non-inverting Op-Amp and then integrated with PC exploit microcontroller ATmega16 as processor of analog to digital data. Data input of microcontroller packed into Visual Basic application program to be turned into signal/graph. This signal refined by using FIR filter to lessen noises and to clarify the signal. Its result is a signal that be able to be used to determine someone lung capacities and volume with error prosentase between 10.953% - 37.81% for normal/relax condition.
