Food sustainability is still one of the main priorities for many countries as it contributes to the economy and stability of the nation. For government in many countries whose peoples consumes rice as its staple food, food self-sufficiency initiatives highly depend on accurate prediction of paddy field map. Mapping paddy field task is a challenging problem which cannot be handled manually especially when the paddy fields are spread out in very wide geographical areas such as those in Indonesia. Fortunately, wide availability of satellite imagery and the advent of deep learning technology in the past ten years have made it possible to improve efficiency of most parts of those manual works involving image semantic segmentation tasks. However, satellite image-based semantic segmentation is a challenging task. High object complexity, cloud partial occlusion, larger image size than a computer memory can stored can hinder accuracy of the image segmentation results. This paper presents a method for paddy field map generating using semantic image segmentation approach in which Pyramid Scene Parsing Net model is used for segmenting satellite imagery. The generated paddy map can be used as a basis for decision-making, especially in the agricultural sector. Analysis of local land use/land cover dynamics. The results of his experiments using SPOT 6 satellite imagery from the Pahung region of Central Kalimantan achieved average training accuracy, best training accuracy and test accuracy of 0.85, 0.86 and 0.89 respectively. These results indicated that the semantic segmentation model is suitable for addressing the same task in different crops.
粮食可持续性仍然是许多国家的主要优先事项之一,因为它有助于国家的经济和稳定。对于许多以大米为主食的国家的政府来说,粮食自给自足的举措高度依赖于对稻田地图的准确预测。水田测绘是一个具有挑战性的问题,特别是当水田分布在非常广泛的地理区域时,例如印度尼西亚。幸运的是,在过去十年中,卫星图像的广泛可用性和深度学习技术的出现使得涉及图像语义分割任务的大部分手工工作的效率得以提高。然而,基于卫星图像的语义分割是一项具有挑战性的任务。高目标复杂性、云的局部遮挡、大于计算机内存存储的图像大小都会影响图像分割结果的准确性。本文提出了一种基于语义图像分割的水田地图生成方法,该方法利用金字塔场景解析网模型对卫星图像进行分割。生成的水田图可作为决策的基础,特别是在农业部门。本地土地利用/土地覆盖动态分析。他利用中央加里曼丹Pahung地区的SPOT 6卫星图像进行实验,其平均训练精度、最佳训练精度和测试精度分别为0.85、0.86和0.89。这些结果表明,该语义分割模型适用于不同作物的同一任务。

A. Afifuddin, D. Nugroho, Muhammad Razzaaq Al Ghiffari, A. Agustan, C. Endyana, Hendarmawan
The establishment of the GNSS Continuously Operating Reference System (CORS) station in Indonesia has given an advantage to wider applications. Ranging from preserving the national spatial reference system, supporting cadastral surveys, and observing natural disasters. The trend of CORS applications is to monitor crustal deformation, discover active tectonics, and study earthquake phenomena. The utilization of GAMIT/GLOBK software has exceeded other GNSS processing software for many applications. This study will elaborate on the strategy and required steps for performing multi-year CORS processing in southern Sumatera, as well as evaluate GAMIT results. Through 19 local CORS stations and 7 IGS stations, alongside setting up several control files, we have successfully created velocity maps and monitored the deformation of each CORS station in Southern Sumatera.

Optimization of Loop Closure Phase on LiCSBAS for Ground Deformation Monitoring in Southern Sumatra 南苏门答腊岛地表变形监测LiCSBAS闭环相位优化
Muhammad Razzaaq Al Ghiffari, D. Nugroho, Afifuddin, A. Agustan, C. Endyana, Hendarmawan
Indonesian territory has an active tectonic, one of which is Southern Sumatra. This is due to the presence of a subduction zone in the west and the Sumatra fault which is parallel to each other. Such geological condition can lead to disasters (e.g earthquakes and tsunamis) whenever it occurs. Accordingly, monitoring ground deformation is an important analysis to do in this area. LiCSBAS becomes an effective open-source tool for observing time-series of ground deformation using InSAR. One of the stages, the loop closure phase is a critical step in generating the number of interferograms and pixels that will be used. The objective of this study is to observe ground deformation in Southern Sumatra by taking the optimal value of the loop closure threshold. The data processing results that the threshold value used is 1.6 rad. Meanwhile, the deformation pattern is generally divided into two areas, the western and eastern parts of Southern Sumatra. The western part close to the Sumatra Fault Zone shows a subsidence at a rate ∼115 mm/year and the eastern indicates an uplift ∼68 mm/year.
印度尼西亚境内有一个活跃的构造,其中之一是南苏门答腊。这是由于在西部存在一个俯冲带和相互平行的苏门答腊断层。这样的地质条件无论何时发生都可能导致灾难(如地震和海啸)。因此,监测地面变形是该地区的重要分析工作。LiCSBAS是利用InSAR观测地表时间序列变形的有效开源工具。其中一个阶段,环路闭合阶段是产生将要使用的干涉图和像素数量的关键步骤。本研究的目的是通过选取环闭合阈值的最优值来观测苏门答腊岛南部的地面变形。数据处理结果表明,使用的阈值为1.6 rad。同时,变形格局大致分为南苏门答腊西部和东部两个区域。靠近苏门答腊断裂带的西部以~ 115 mm/年的速度下沉,东部以~ 68 mm/年的速度隆起。

Mangroves have the capabilities to both mitigate and adapt to climate change impact. However, it varies between species. Therefore, it is substantial to upscale mangrove explorations and studies to the species level. This study aims to perform a spectral-library-based linear spectral unmixing (LSU) analysis technique on Landsat 9 OLI-2 imagery as an alternative to the conventional mangrove species mapping methods. We used the center wavelength of Landsat 9 OLI-2's B2, B3, B4, and B5 bands to define the spectra of Sonneratia alba, Rhizophora apiculata, and Avicennia marina. We performed the LSU analysis on the Muaragembong mangrove forest area, Bekasi, West Java, Indonesia as the area of interest. The result showed that the mangrove species has a unique spectral signature. The reflectance is slightly higher at around 500–600 nm and lower at 750–770 nm than the typical vegetation spectral signature. Most of Muaragembong is covered with R. apiculata and A. marina. However, there is a distinctive spatial distribution pattern for each species. Based on the RMSE result, the model can produce a ±0.3% error in each pixel. Empirical evidence from the ground truthing helped to validate the distribution pattern. It is associated with environmental factors, such as supporting substrate and water access. This paper concludes that it is possible to perform the LSU analysis using multispectral satellite data for a large-extent mangrove species mapping. However, it is mandatory to validate the result on a ground-truthing process.
红树林具有减缓和适应气候变化影响的能力。然而,它在不同物种之间是不同的。因此,将红树林的探索和研究提升到物种水平具有重要意义。本研究旨在对Landsat 9 OLI-2图像进行基于光谱库的线性光谱解混(LSU)分析技术,作为传统红树林物种制图方法的替代方案。利用Landsat 9 OLI-2卫星的B2、B3、B4和B5波段中心波长对海桑、尖根蒿和海棠进行了光谱分析。我们对印度尼西亚西爪哇勿加西的Muaragembong红树林区域进行了LSU分析。结果表明,红树林物种具有独特的光谱特征。与典型植被光谱特征相比,500 ~ 600 nm处的反射率略高,750 ~ 770 nm处的反射率略低。牡丹峰的大部分地区都覆盖着尖叶金莲和金针莲。然而,每个物种都有独特的空间分布格局。基于RMSE结果,该模型在每个像素上可以产生±0.3%的误差。来自实地调查的经验证据有助于验证这种分布模式。它与环境因素有关,如支撑基质和取水途径。本文的结论是,利用多光谱卫星数据进行LSU分析可以进行大范围的红树林物种制图。然而,必须在地面测实过程中验证结果。

Spatio-Temporal Analysis of SO2 Concentrations Due to Volcanic Eruptions in Indonesia Using Sentinel-5P with Earth Engine Platform 基于Sentinel-5P和Earth Engine平台的印度尼西亚火山喷发SO2浓度时空分析
Nur Aini Qolbi Fadhilah, Nurya Ramadhania, H. Sanjaya, B. M. Sukojo, Meuthia Djoharin Poespo
Based on data from MAGMA PVMBG, the Geological Agency of the Ministry of Energy and Mineral Resources, in 2019, about 10 mountains have erupted and some have erupted more than twice. Therefore, a spatiotemporal analysis was carried out on SO2 concentrations due to volcanic eruptions in Indonesia in the 2019-2022 period through Sentinel-5P image data with the help of a cloud-based application, Earth Engine. Analysis was carried out at pre-eruption, during an eruption, and post-eruption to determine the difference. This analysis is performed over a weekly time frame. From the results obtained, the concentration of SO2 in the eruption area increased during the eruption and tended to be high compared to the concentration during pre and post-disaster. The distribution of sulfur dioxide is influenced by wind direction and speed, so the sulfur concentration is not always high near the area around the eruption. The value of SO2 concentration in the volcanic eruption area ranges from 0.00-0.007 mol/m2. Based on the correlation test with BMKG environmental data, the surface temperature parameter is known to be positively correlated with the SO2 value and has a negative correlation with humidity. The data that has been validated is then displayed on the website with a simple and easy-to-understand interface for users.
根据能源和矿产资源部地质机构MAGMA PVMBG的数据,2019年约有10座山脉喷发,有些火山喷发了两次以上。为此,利用Sentinel-5P遥感影像数据,借助基于云的Earth Engine软件,对2019-2022年印尼火山喷发SO2浓度进行了时空分析。分析在喷发前、喷发期间和喷发后进行,以确定差异。该分析是在每周的时间框架内执行的。结果表明,火山喷发期间,火山喷发区SO2浓度呈上升趋势,且与灾前和灾后浓度相比呈较高趋势。二氧化硫的分布受风向和风速的影响,因此火山喷发附近的二氧化硫浓度并不总是很高。火山喷发区SO2浓度范围为0.007 ~ 0.007 mol/m2。通过与BMKG环境数据的相关试验可知,地表温度参数与SO2值呈正相关,与湿度呈负相关。经过验证的数据然后显示在网站上,为用户提供简单易懂的界面。

Therefore, a spatiotemporal analysis was carried out on SO2 concentrations due to volcanic eruptions in Indonesia in the 2019-2022 period through Sentinel-5P image data with the help of a cloud-based application, Earth Engine. Analysis was carried out at pre-eruption, during an eruption, and post-eruption to determine the difference. This analysis is performed over a weekly time frame. From the results obtained, the concentration of SO2 in the eruption area increased during the eruption and tended to be high compared to the concentration during pre and post-disaster. The distribution of sulfur dioxide is influenced by wind direction and speed, so the sulfur concentration is not always high near the area around the eruption. The value of SO2 concentration in the volcanic eruption area ranges from 0.00-0.007 mol/m2. Based on the correlation test with BMKG environmental data, the surface temperature parameter is known to be positively correlated with the SO2 value and has a negative correlation with humidity. The data that has been validated is then displayed on the website with a simple and easy-to-understand interface for users.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124764339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implementation of Cloud-Based Drone Navigation for Swarm Robot Coordination 基于云的无人机导航在群机器人协调中的实现
Ja'far Shadiq Alatas, K. Priandana, Medria Kusuma Dewi Hardhienata, Wulandari
Smart agriculture 4.0 has recently been implemented in Indonesia to enhance agricultural productivity through the use of advance technology. Unmanned Autonomous Vehicle (UAVs) is one of the technologies that have been utilized in the agricultural sector to improve production quality and quantity. Although some advanced technology has been used, currently there are some challenges that remain to be solved to implement multi-UAV in the real environment. Some of these challenges include battery limitations in UAV and the long duration to queue at the charging station. To address this issue, a previous study has proposed Cloud Based Drone Navigation (CBDN) algorithm that can be employed to optimize multi-UAV coordination by selecting the best flight path for the UAV to reach a charging station. Such an approach has resulted in reducing the waiting time of UAVs to be charged. However, the algorithm has not considered swarm robot parameters. This study aims to analyze the use of CBDN algorithm with parameters derived from swarm robots. The performance of the CBDN algorithm will then be evaluated and compared to the Shortest Flight Time (SFT) and Individual Reservation Navigation System (IRN) algorithms as two benchmark algorithms, in terms of the total travel time. By considering real swarm robot parameters, the CBDN algorithm has resulted in an average total travel time of 17.44% less than the average total travel time of SFT and 17.25% less than the average total travel time of IRN.
智能农业4.0最近在印度尼西亚实施,通过使用先进技术提高农业生产力。无人驾驶汽车(uav)是农业部门用于提高生产质量和数量的技术之一。虽然已经采用了一些先进的技术,但目前要在真实环境中实现多无人机仍存在一些有待解决的挑战。其中一些挑战包括无人机的电池限制和在充电站排队的时间长。为了解决这一问题,已有研究提出了基于云的无人机导航(CBDN)算法,该算法可以通过选择无人机到达充电站的最佳飞行路径来优化多无人机协调。这种方法减少了无人机充电的等待时间。然而,该算法没有考虑群机器人的参数。本研究旨在分析基于群体机器人参数的CBDN算法的使用。然后,CBDN算法的性能将被评估,并与最短飞行时间(SFT)和个人预订导航系统(IRN)算法作为两种基准算法进行比较,以总旅行时间为标准。在考虑真实群体机器人参数的情况下,CBDN算法的平均总行程时间比SFT算法的平均总行程时间少17.44%,比IRN算法的平均总行程时间少17.25%。

The volcanic eruption provides valuable products and resources, but can also endanger people's lives, property, and activities. This research models the potential hazards from Mount Batur's eruption to mitigate the impacts in the future. Our research focused on numerical models of volcanic hazards with input parameters derived from geology, deformation, seismic, and geochemical data. We acquired high-resolution DEM data obtained from DEMNAS. We compare modelling results with the existing hazard map of Mount Batur.
