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 °

Penelitian ini dilaksanakan pada bulan Juni 2019 di Pulau Tikus Provinsi Bengkulu untuk mengetahui bagaimana kepadatan bintang laut berduri (A. planci), bagaimana kondisi terumbu karang serta bagaimana kepadatan bintang laut berduri (A. planci) pada ekosistem terumbu karang yang dianalisis berdasarkan tutupan karang hidup di Pulau Tikus. Metode yang digunakan adalah metode survey. Pengambilan data kondisi terumbu karang dilakukan menggunakan metode Underwater Photograph Transect (UPT) dan pengambilan data kepadatan A. planci menggunakan metode line Intercept Transect (LIT). Kondisi Terumbu karang Pulau Tikus Provinsi Bengkulu pada 3 stasiun penelitian kedalaman 4 meter didapatkan masuk dalam kategori sedang-bagus. Pada stasiun I didapatkan persentase tutupan 44,4% atau dalam kategori sedang, pada stasiun II didapatkan persentase tutupan 59,33% dan stasiun III didapatkan persentase tutupan 59,04% yang masuk dalam kategori baik. Sedangkan pada kedalaman 9 meter didapatkan persentase tutupan dalam kategori buruk yaitu 13,93-20,20%. Kepadatan A. planci pada 3 stasiun penelitian yang masing masing dilakukan pengambilan data pada kedalaman 4 dan 9 meter semuanya masih dalam status populasi normal atau alami dengan kepadatan tertinggi yaitu 0,004 ind/m² sehingga belum memberikan ancaman yang berarti bagi ekosistem terumbu karang. Kepadatan A. planci pada masing masing stasiun penelitian juga tidak memperlihatkan perbedaan baik itu berdasarkan kedalaman maupun berdasarkan stasiun

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
