Perancangan Sistem Deteksi Objek pada Robot Krsbi Berbasis Mini Pc Raspberry Pi 3

KRSBI Wheeled is One of the competitions on the Indonesian Robot Contest,.  It is a football match that plays 3 robot  full autonomous versus other teams. The robot uses a drive in the form of wheels that are controlled in such a way, to be able to do the work the robot uses a camera sensor mounted on the front of the robot, while  for movement in the paper author uses 3 omni wheel so the robot can move in all directions to make it easier  towards the ball object. For the purposes of image processing and input and output processing the author uses a Single Board Computer Raspberry PI 3 are programmed using the Python programming language with OpenCV image processing library,  to optimize the work of Single Board Computer(SBC) Raspberry PI 3 Mini PC assisted by the Microcontroller Arduino Mega 2560. Both devices are connected serially via the USB port. Raspberry PI will process the image data obtained  webcam camera input. Next, If the ball object can be detected the object\u27s position coordinates will be encoded in character and sent to the Microcontroller Arduino Mega 2560. Furthermore, Arduino mega 2560 will process data to drive the motors so that can move towards the position of the ball object. Based on the data from the maximum distance test results that can be read by the camera sensor to be able to detect a ball object is ±5 meters with a maximum viewing angle of 120 °

Diversity of Macrozoobenthos in Kuala Indragiri Coastal Water Riau Province

This research was conducted in February 2015 located in the coastal area of Kuala Indragiri, Riau Province. This purpose of this study was to know the diversity macrozoobenthos and observe the relevance sediment content organic matter with the abundance of macrozoobenthos. The method used in the study was a survey method. Sampling macrozoobenthos was conducted by using 50 meters transect line, from the lowest tide limit to the highest tides and on each transect three plots with a size of 1 x 1 m2 was applied. The research recorded 13 spesies of macrozoobenthos consisting of 4 classes, namely class Gastropoda (Telescopium Telescopium, Eupleura caudata Chicoreus capucinus, Strombus sp, sp Cherithidea, Nerita sp, Babylonia spirata, Morulla striata), Bivalves (Anadara granosa, Placuna placenta), Crustaceans (Uca coartata, Sylla serrata), and Polychaetes (Eunice viridis). Diversity of macrozoobenthos was medium, nothing species dominates and uniformity was evenly. The average content of organic matter was 7.23%. Correlation of sediment organic matter with abundance macrozoobenthos was significant r = 0.907

The Abundance of Epibenthic Dinoflagellates Toxic (Gambierdiscus SP., Prorocentrum SP. and Ostreopsis SP) in Seaweed Padina SP in Coastal Waters of Sungai Nipah Village Pesisir Selatan District West Sumatra Province

The species existence of dinoflagellates , i.e. Gambierdiscus sp., Prorocentrum sp. and Ostreopsis sp in the waters can cause disease, poisoning and blooming. This will cause disruption of aquatic ecosystems that cover the water surface and light penetration into the body of water will be hampered. Research to determine the abundance of toxic dinoflagellate epibenthic on seaweed Padina sp. in Sungai Nipah waters was conducted in August 2015. Sampling of epibenthic dinoflagellates attached to Padina sp was performed in three stations and each station consists of three sampling points.The results showed that the highest abundance epibentic toxic of dinoflagellates in the coastal waters of Sungai Nipah found at station 3 (803.28 cells / g). The highest abundance from all stations was a genus of Prorocentrum sp., with the total number of 947.74 cells/g, genus Gambierdiscus sp. had the smallest abundance at each respective station with a total of 41 cells/g while Ostreopsis sp has a evenly abundance in almost every station with a total abundance 562.93 cells/g
