<![CDATA[Securing detention rooms in Indonesia, using manual methods from humans to secure them. Officers check the detention room periodically. Several cases that occurred, such as the escape of prisoners from the Cawang Police and the Lhoksukhon Detention Center, the detainees broke into the bathroom wall using metal bars to be used as a media for breaking the walls. To prevent recurrence of cases, an early detection design is needed when there is a detention room indicated that it will be damaged by installing a vibration detection device on the wall. In this study, the SW-420 vibration sensor is used as a vibration detector when there is a wall to be broken into and several cameras installed in the corridor to visually monitor the occupants of the detention room. Vibration data will be sent to the detention room website via Arduino Uno, while the IpCamera will be connected to the router to display the video capture results on the website. For example, the bathroom plan for the detention room at the Gondanglegi Police Station that has been made, the sensor node is placed at the center point of the bathroom wall at a position of 60 cm which divides it into 2 parts. Arduino Uno will dynamically have IP when connected to the router using a Lan cable. Based on the experiment in the previous chapter, how to adjust the sensor sensitivity can be done by turning the sensitivity adjustment and adjusting the threshold on the website code.]]>

<![CDATA[Conventional access control systems such as manual light switches are now being developed with electric light switches that can be controlled remotely using a web. Raspberry Pi is one of the newest technologies, namely a mini computer that can be used in an automatic access control system. This technology can be applied using one of the sciences of artificial intelligence, namely fuzzy logic control. Fuzzy logic is an appropriate way to map an input space into an output space. In this final project research is designed a home electric device control system using fuzzy logic based on Raspberry Pi and Web. The Arduino nano is also used in the system as a fuzzy lamp controller. To be able to control via the Raspberry Pi, an ip is needed for communication between the web and raspberry, namely 192.168.1.204. From the test results on the lamp, the light intensity and lamp voltage change based on the light sensor input, the voltage of 10 volts of the lamp produces 10 lux of light intensity, 60 volts = 51 lux and 220 volts = 320 lux while for the fan the speed is directly proportional to the amount of temperature. When the temperature is set to 28 oC and the sensor reads a temperature of 28.25 oC the PWM output of the fan = 95 and when the temperature is 34 oC the output is 40. The greater the PWM output, the slower the fan rotation.]]>

<![CDATA[FM radio broadcasting is a wireless communication system. Transmission in the frequency 88-108 MHz requires a bandpass filter to avoid interference with frequencies adjacent to the radio transmitter. The type of filter that has a fairly good performance is the Chebyshev filter with a fairly high level of steepness. However, to get a high level of steepness, a fairly large element value is required. So, in this study adding the m-derived series to give a steeper filter response without adding more element values.The purpose of this thesis is to determine the effect of adding an m-derived section to the chebyshev bandpass filter. The parameters tested are passband bandwidth, stopband bandwidth, shape factor, insertion loss, roll off, and power attenuation when used on the transmitter.Based on the measurements that have been made, it can be seen that the bandpass filter without m-derived has a maximum insertion loss value of 7 dB and a minimum insertion loss of 9 dB, while the bandpass filter with m-derived is 11 dB and 13. In the bandpass filter without m-derived and m-derived have a passband bandwidth of 27 MHz and 29 MHz and a stopband bandwidth of 70 MHz and 50 MHz. So that the bandpass filter without derived and m-derived has a shape factor value of 2.59 and 1.72. In the implementation using the transmitter, the bandpass filter without m-derived has a power attenuation of 2.53 dB while the m-derived bandpass filter has an attenuation of 1.5 dB.]]>

<![CDATA[The problem that often occurs in malls or supermarkets is the use of EDC as a non-cash payment tool for alternative customers. However, the use of EDC machines sometimes experiences problems, namely when customers enter data so that transactions take longer, so this study aims to analyze the optimization of EDC placement in shopping center buildings. This research method is to measure the parameters, namely the RSCP and the closest antenna coverage from the EDC. In this study, three samples were taken, namely Cassa 1, 2 and 3 at Matahari Department Store Malang Town Square. The results of this study were obtained that the Drive Test in the Matahari room showed that Cassa-1, Cassa-2 and Cassa-3 received RSCP with green color which means good. Two of the three tools, namely Drive Test and Mobile can display RSCP with a value that is not too much difference. Especially for EDC is only able to visually display the RSCP and the results of previous calculations, the value of ten antennas which is in the Matahari room has a coverage area below 10 m. And the UG-12 antenna, which is the closest antenna to Cassa-3, that is outside the antenna coverage, while the UG-08 antenna can still reach the Cassa-3 area. This shows that the placement of EDC has met the requirements to get adequate signal quality and the position of the Cassa table can be moved according to the antenna coverage calculation on the Link budget and Path Loss calculations]]>
