Due to the working principle of the movement of the motor speed Quadcopter dotted on each side. BARELANG COPTER NAZA has modules for system balance when flying. NAZA within this module has a 3-axis accelerometer sensor, 3-axis gyroscope and a barometer to sense the attitude and altitude.
Lampu Pijar Sebagai Ballast Pada Lampu Tl 10 Watt
(Politeknik Negeri Batam, 2013-06-20) Manurung, Lovenri Soaduon; Istardi, Didi
The growing need for fossil fuels for electrification caused greenhouse gas production (TL) increases. It is to be anticipated with the use of energy saving one done on the load side. Replacement of conventional ballasts with electronic ballasts in fluorescent lamps is one such effort. From laboratory observations, the replacement produce higher power factor and power losses are lower so as to provide potential energy savings reach 65-75% of conventional ballasts. Constraint that arises is that the findings suggest that most of the test sample produces a lower light intensity when compared with fluorescent lamps with conventional ballast. In addition, it was found that the resulting flow is very high electronic ballast. In order aspects of energy savings can be achieved with good, ballast products are sold in Indonesia need to standardize. At the researches task this final for energy savings and material on the lamps TL and Trafo (Ballast) which used on generally which will use the Lamps Pijar as Ballast Lights TL which its usefulness can be illuminate two the room at once with using the power on the lights TL such the circuit for turn on lights TL who generally turned on the AC mains voltage. 1 piece as the incandescent lamp ballast fluorescent lamp with optimal light level is by using incandescent ballast that has a minimum output power of 4-6 times greater than the fluorescent lamp to be lit, where incandescent bulbs will be linked in parallel with the starter to light, heat and turn on electrode the lights TL which will get a voltage who high enough (less more 400 Watt) which reduces the blurbs on the electrode dwi metal and starter give heating time initial is right for the Ignition the lights TL at its optimum.

Algoritma Menghindari Lawan pada Robot Barelang 7.1
(Politeknik Negeri Batam, 2018-06-06) Tinambunan, Devi Gusnaensi; Sugandi, Budi; Prayoga, Senanjung
KRI is an Indonesia robot contest which consists of 4 main categories and one of them is the Indonesia Soccer Robot Contest (KRSBI). On the rules during the game of Wheeled KRSBI, the robots are strictly forbidden to hit or push the opponent robot. If that is the case then the robot will get a yellow card. The robots also are at risk of getting a red card then ejected from the field if the robot hits an opponent with a bang. To prevent this, the author has designed an algorithm to avoid and reduce the intensity of a robot doing a physical contact with opponents. The algorithm was formed from the combination of vision cameras and sensors ping. The camera will detect the opponent robot based on the color of its identity. Color identity must be filter for separating it from the background so it can be identified. The filter used is the color filter HSV plus filter erosion, dilation, and controls the blob. The opponent's robot detection is also facilitated with the use of a Parallax Ping sensor. Sensors ultrasonic wave shooting into the opponent's robot and then receive back the reflections so that known distance between them. After testing done against this system, robot Barelang 7.1 can detect opponent robots with good result. The robot can detect his opponent from a distance of 50 cm to 5.5 meters. Once detected, the robot would avoid his opponent while approximately ≤ 40 cm.
Rancang Bangun Pendeteksi Api Berbasis Vision untuk Pengendalian Kamera Pengawas
(Politeknik Negeri Batam, 2018-01-03) Riyadi, Dedy Slamet; Aisyah, Siti
Fires is a disaster caused by flame or uncontrolled burning that can endanger human life, buildings and ecology. Fires are unpredictable when it will happens. For examples forest fire, Fires in housing or building can occur during the day or night. The use of CCTV/webcam which can monitor the location for 24 hours is very effective to prevent the occurrence of fire. Therefore, we built a system that can detect early fire based on image processing by using the method of HSV color segmentation . The system processes the data image which captured by the webcam in real time through the LabVIEW software. The fire detection process is done by using Image enhancement method and combined with result of HSV color segmentation to produce the segment object in the form of blob so that it can know the number of detected object and the center point of the fire object. Based on the results of testing and analysis, it is concluded that user control in terms of color sampling and color tolerance of fire objects have an important role in the segmentation process. The accuracy of the system that has been made is 98% with error of 0.25% for the detection conditions at night. The system is able to detect the presence of fire in real time around 30 fps at a resolution of 1024 x 768. Error detection is mainly caused by light reflections from lights or light sources on the surface of shiny objects.
Meteran Air Prabayar Berbasis Smartcard
(Politeknik Negeri Batam, 2013-06-03) Triwandana, Jati; Oktani, Dessy
In the present era, the development of technology, water meter in the residential- housing, buildings, ports, airports and others in Indonesia are still using water payments at the end, then on this occasion the author is trying to create an innovation-based Prepaid Water Meter smartcard. The purpose of the creation of this tool is to reduce HR (human resources) required by the water service provider. The tool is divided into two parts, namely a tool that serves as filler RFID Card (owned water services provider) and a tool that serves as RFID reader card prepaid water meter at the same time (being in buildings that use water). Through the interface of Visual Basic water flow data that has been purchased by the consumer is sent to the device through the RFID Card RFID Card filler. Then after consumers enter the data contained on the RFID card prepaid water meter to existing customers in place, then the prepaid water meter opens valve solenoid valve so that water can flow further discharge of water that flows will be measured using a water flow sensor, when water discharge was similar to that measured water discharge data purchased the solenoid valve is closed so that the water can not flow. Automatically when the consumer wants to use water more then the consumer must replenish its RFID Card.

(Politeknik Negeri Batam, 2014) Budiarto, Arif Wahyu; Istardi, Didi; Gozali, M.Syafei
Soda fountain system automatically uses the proximity sensor as a sensor to detect the height of a glass which then detected using fiber optic sensors to detect the presence of glass, this tool works by using a timer as a controller of the total volume of water flowing into the glass and use as tap water solenoid valve electrically. Systems of this tool using a smart relay by using three different size glasses high but the same diameter glass used between glass high, medium and small. The process of filling a small glass of water for the charging time is needed is 9 seconds, for glass was required charging time is 12 seconds and for a large glass of the required charging time is 18 seconds. Average error value in a small glass of water volume is 15.19% and the charging time error is 8.88%, while the glass was the average size of the error value is 5.04% water volume and water charging time error value is 3, 11% and testing for large size glass of water volume error value is 1% with water filling time error value is 0%.

(Politeknik Negeri Batam, 2014-06-06) Ilham, Ilham; Oktani, Dessy; Jamzuri, Eko Rudiawan
To reduce the encroachment of misconduct are often performed by employees at PT Schneider Electric then made a portal in the form of automated tool with a working system of measurement tools ESD results. ESD itself is a power that exist in every human body that can damage sensitive electronic equipment against electrical flow. The working system is quite simple tool that will work if checking footwear ( safety shoes ) into the ranges between 0.75MΩ ~ 100MΩ or checking wrist ( wrist trap ) into the ranges between 0.75MΩ ~ 10MΩ. From the data taken from multiple experiments can be concluded that the tool is able to work in a predetermined resistance measurement. In manufacturing, this automatic tools such as portals utilizing ESD signal as input, the PLC to programming, four proximity sensors to be installed on Pneumatic Cylinder and four distance sensors to detect employees and for its safety.
