UAV application for site suitability mangrove replantation program, case study in Pasuruan and Probolinggo, East Java

Abstract

In the northern coast of East Java, mangrove naturally growth along the coastline of most regencies, and becomes the important factor in the sustainability of fisheries, protection and other environmental services for communities in coastal areas. The last few decades, satellite remote sensing becomes the most widely used tool for mangrove monitoring purpose. Various types of sensory satellite images are used for mapping areas, types and densities, estimating the mangrove biomass. Meanwhile, UAV (Unmaned Aerial Vehicle) is rapidly developed and quite affordable. Various footages and photogrammetry works carried out with the lightweight UAV. Therefore, utilizing UAVs for capturing mangrove areas can be an effective solution to identify area where rehabilitation should be conducted. The research aimed to use the consumer grade DJI Phantom 4 Pro for mapping 92,6 Ha mangrove area in Rejoso (Pasuruan) and 69,37 Ha of Sumberasih (Probolinggo). Result of this study shows the capability of UAV to provide detail mangrove image (canopy density, characteristics and environmental profile), which can be used to support the management activities, particularly mangrove replantation program. Also, it could be a low cost solution and time effective of mangrove monitoring, compared with previous approach of high-resolution satellite imagery.

Evaluation of the quality of mangrove ecosystems using macrozoobenthos as bioindicators in the Southern Coast of East Java, Indonesia

“…Some beaches that have experienced degradation are Cengkrong Beach (Mughofar et al 2018), Sine Beach (Saputra et al 2020), Getem Beach, Kondang Merak Beach, and Clungup Mangrove Conservation (Hakim et al 2017;Retnaningdyah et al 2021). Continuing human activities without any countermeasures can reduce the carrying capacity (Malik et al 2015), which decreases the quality of mangrove ecosystem services (Rohila et al 2017;Darmawan et al 2020). Ideally, degraded ecosystem should be restored to its natural condition (Nichols et al 2019).…”

Existing and emerging uses of drones in restoration ecology

“…Other studies have used off‐the‐shelf drones (e.g., DJI Phantoms) along transects to map intertidal, coastal (mangrove) and inland vegetation (Cruzan et al, 2016; Darmawan et al, 2020; Rossiter et al, 2020). Aerial images are collected by the drone and used to create orthomosaics and digital surface models (DSM) to map vegetation and landform elevation differences.…”

“…Oleh sebab itu apabila ada beberapa kendala tersebut pada umumnya peneliti menggunakan teknologi UAV (Unmaned Aerial Vehicle). Teknologi UAV yang berada pada ketinggian yang lebih rendah dari awan memungkinkan mendapat data yang tidak tertutup oleh awan dan sesuai waktu yang dibutuhkan saat penelitian [17].…”
