This study aims to analyze changes in land cover due to urban growth in Central Ternate District, Ternate City using The Automata- Markov Chain. Cellular Automata- Markov Chain is used to analyze and predict land cover changes in 2002, 2012, 2022 and 2031. The results showed that residential land will continue to experience an increase in area along with population growth and the high demand for land to settle. The results of this study are expected to be input in policy making related to the arrangement and utilization of space in The Central Ternate District in the future.</p> 2023-01-17T04:54:18+00:00 ##submission.copyrightStatement## Stockpile Volume Estimation Calculation Based on Terrestrial Laser Scanner (TLS) Data Acquisition and 3D Surface Visualization 2023-01-28T01:47:47+00:00 Adkha Yulianandha Mabrur Feny Arafah Adi Sulistianto <p>Stock taking is a series of activities to calculate the stock of goods that are still stored in the warehouse to be marketed. There are many activities covered in it, ranging from calculating the number of goods, conducting direct inspections, and structuring that will facilitate business operations when a certain product is needed. One of these activities is also carried out in the mining sector. Coal stock-taking is a survey activity carried out in the coal yard area to calculate the volume of the stockpile and coal tonnage after being multiplied by the density value. Large-dimensional coal stocking must be carried out quickly, accurately and in detail. The need for this can be obtained using laser scanner technology. Laser scanner is a tool designed to scan the surface of an object and represent it in 3D in the form of a height density point cloud. Based on this, in carrying out stock-taking calculation activities, measurements are needed which mainly aim to find out the stockpile volume and density in the fourth quarter of the Adipala PLTU Coal Yard. Stockpile measurement method using volumetric method. Measurement using a Laser Scanner tool to obtain the shape of the stockpile area is by seizing the entire surface of the Stockpile by setting the resolution of the density of coordinate points (x, y, z) as needed. Tool displacement when measurements are made on every detail of the Stockpile curve. Based on the calculation results, it is known that the volume value of the coal stockpile on the west side coal yard is 121,420,574 m3 and the east side coal yard is 88,230,355 m3 on. The total volume of coal amounted to 209,650,929 m3 then multiplied by the density of the bulk density survey results and obtained the tonnage of 180,384,417 MT.</p> 2023-01-28T01:45:59+00:00 ##submission.copyrightStatement## Mapping The Agriculture Land of The Land Farmers in The South Coast of Kulon Progo 2023-01-28T02:32:40+00:00 Indreswari Suroso Ferry Setiawan <p>The south coast land of Kulon Progo on the beginning was sandy and infertile soil. The land then was converted into agriculture land, chilli farm based on the idea of the agriculture expert, Mr. Karman. This study aimed to map the agriculture land in Bidadara coast, Panjatan district, Kulon Progo because of the the success of the coastal farmers on producing an abundance of chilli harvest. The method used was interviews and field observation. The deviced used for mapping was &nbsp;DJI Mavic 2 Pro multicopter drone operated approximately for 20 minutes. The result of this study was aerial photos of drone shots with a height of 20 meters, 30 meters, and 50 meters above ground level onto the soil conditions adjacent to Bidara Beach, Panjatan, Kulon Progo. It was seen that the stretch of coastal land was planted with coconut trees and chilies. Hence, no wonder that the coastal land farmers are rich because of fantastic income from the farm. It is proven that the cultivation of this chili plant can improve the economy of the farming community on the South Coast of Kulon Progo.</p> 2023-01-28T02:24:11+00:00 ##submission.copyrightStatement## Identifying Probable Slip Surface in Wanurejo, Borobudur District, By Subsurface Analysis Utilizing the Dipole-Dipole Configuration of Resistivity Method 2023-01-31T05:36:19+00:00 Nurul Dzakiya Robertus Belardo Laksmana Radhitya Adzan Hidayah <p>Research has been carried out on the existence of slip surfaces in Wanurejo, Borobudur District, Magelang Regency, Central Java. The location of the slip surface is identified using the resistivity method of the dipole-dipole configuration. This research was conducted at a relatively flat measurement location and at an altitude of around 95–105 meters above sea level. Measurements were made on 6 different lines with a length of track 1 of 250 m. The results of data processing indicate that the layer that acts as a slip surface is a layer of clay. The clay layer has a resistivity value ranging from 15 to 35 ohm.m, which is relatively thin, so it has the potential to become a slip surface because it is located between two rocks that have a significant resistivity contrast: compact andesite rock and water-saturated sandstone. If the water-saturated sandstone layer is no longer able to withstand the weight above it, the surrounding andesite rocks will easily slip. This is also reinforced by the presence of a layer of clay that is slippery, so the potential for landslides or slipping is greater.</p> <p>&nbsp;</p> 2023-01-31T05:34:06+00:00 ##submission.copyrightStatement##
