The method used for this study are using the combination of structural lineament analysis, scanline with window sampling and Rock mass rating (RMR) calculations. The analysis results of the fourteen observed slope sites showed significant outcome, which seen in the structural lineament show dominant trend from northwest-southeast, which also correlate from the measurement of discontinuity by using scanline with window sampling. From RMR calculation, value showed range between 17 - 42 which belonged to class V (Very Poor Rock) - class III (Medium Rock ). Integration data of structural lineament, scanline method and RMR analysis suggested that 1 slope included in the very poor rock category, 12 slopes are poor rock category, and 1 slope in the medium rock category. So, it can be ascertained that most of the slopes will potentially be prone to landslides.</p> <p><strong>Keywords:</strong> Slope Stability, RMR, Structural Lineament, Pangkalan Koto Baru, West Sumatra.</p> 2018-09-17T06:43:22+00:00 ##submission.copyrightStatement## https://jurnal.polibatam.ac.id/index.php/JAGI/article/view/952 Analysis Of Mapping Multicopter Drones In The Entrance Area Of Prospective New Airports In Congot, Temon, Kulonprogo, Yogyakarta 2018-10-17T06:08:43+00:00 Indreswari Suroso indreswari.suroso@gmail.com <p>This research use multicopter drone. This mapping was carried out at the entrance area of the prospective new airport precisely at the Congot beach area, Temon district, Kulonprogo district with a multicopter drone. This drone is capable of recording an altitude of 100 meters above ground level and can photograph an area of 1.5 km. This study used a drone type multicopter The vehicle specifications are as follows: Frame: F450; Flight Controller: DJI Naza M-Lite; Propeller: 1045 Prop; motorbike: brushless sunnsky 980 kVa; ESC: Skywalker 40 Ampere 3s; Battery: Ace 3s Gens 5000mAH; Remote: Turnigy 9XR with Frsky Tanseiver; and camera: Xiaomi Yi 4k International edition. The height of a multicopter drone reaches 30 meters, can take an area of up to 1 km and a flight time of 15 minutes. The advantage of this multicopter is that it uses a DJ I Phantom camera classified as stable for the light weight drone class. So for terrain with high wind speed, this multicopter drone is still able to maintain its position in the air. The Kulonprogo Regional Government and the Congot Radar Unit really appreciate this mapping because it is very helpful in mapping the entrance of new prospective airports in Kulonprogo.</p> <p>&nbsp;</p> 2018-10-17T06:08:42+00:00 ##submission.copyrightStatement## https://jurnal.polibatam.ac.id/index.php/JAGI/article/view/968 Hydro-oceanographic condition (Tide, Sea Current, and Waves) of Nongsa Batam Sea 2018-12-13T05:53:29+00:00 Sudra Irawan sudra@polibatam.ac.id Riza Fahmi rizafahmi@gmail.com Muhammad Zainuddin Lubis lubiszainuddin@gmail.com Satriya Bayu Aji satriya@polibatam.ac.id Arif Roziqin arifroziqin@polibatam.ac.id Hanah Khoirunnisa hanah@polibatam.ac.id <p>Tanjung Bemban is one of the seas found in the Nongsa sub-district, Batam city which is currently developed as a tourist attraction. This research aims to find out the hydro-oceanographic component, which consists of tide and the current and wave pattern in the sea of Tanjung Bemban Nongsa. To collect the data regarding tide, Tide Pole method, using measuring sign, is used, To collect data of sea current, Float Tracking (Lagrangian) method, by measuring distance and displacement of floating objects in the sea, is utilized,&nbsp; To collect the data of the wave, Wave Pole method, by measuring wave height, is employed. Based on the result of the research, it is clear that the tide of the sea is categorized as the semi diurnal, since there are two tides in one day with identical height, which occur sequentially and regularly. The highest flow reaches 260 cm and the lowest ebb 19 cm in the 4 days of observation, with 15 minutes interval. The measuring of ocean current is carried out for every 30-second intervals. Current velocity in Nongsa sea ranges from 0.02 m/s to 0.26 m/s. The current moves from east to southwest and west, even though some move northwest and north. Wave height is quite low, between 18 cm and 23 cm. Hydro-oceanographically, the Tanjung Bemban Nongsa area can be developed into a strategic tourism area</p> 2018-12-13T05:47:24+00:00 ##submission.copyrightStatement##
