The spread of Covid-19 is very much influenced by human activity and mobility. Human activities are also closely related to air pollutant emissions. High concentrations of air pollutants during the Covid19 pandemic will increase the risk of being exposed to Covid-19. Jakarta and its surrounding area (known locally as Jabodetabek) have high population density. These cities are economic and industrial centers. Air pollutant emissions in these cities are very high. High concentrations of air pollutants during the Covid-19 pandemic will increase the risk of being exposed to Covid. To anticipate this problem, the government made a Large-Scale Social Restriction Policy (PSBB). Limited human activities, in addition to having an impact on reducing the risk of humans being exposed to Covid-19 from the droplets released by tested-positive of Covid-19, also have an impact on reducing emissions of air pollutants so that they can reduce the risk of being exposed to Covid-19. Several variables that influence vulnerability and risk to exposure to Covid-19 are the distribution of settlements, roads, economic centers (markets, business centers, industrial centers), and human mobility. In this study, we will also analyze the role of green open space on the risk of exposure to Covid-19. Green open space plays an important role in reducing air pollutants so that it will also affect the risk of being exposed to Covid-19. This study aimed to 1) examine the distribution of air pollutants based on the vulnerability and risk of COVID-19 in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek), and 2) examine the results of the overlay between land cover and vulnerability and risk to Covid-19.</p> Siti Badriyah Rushayati, Rachmad Hermawan, Yudi Setiawan, Arif Kurnia Wijayanto, Lilik Budi Prasetyo, Prita Ayu Permatasari Copyright (c) 2020 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32550 Thu, 31 Dec 2020 00:00:00 +0700 Behaviour and perception of community on peat fire in Ogan Komering Ilir, South Sumatera Province http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32725 <p><em>South Sumatera Province experienced the worst peat fires in 2015, where the larger area is located in Ogan Komering Ilir (OKI) District. Human activity is a very important factor in causing forest and peatland fires,because in fact nearly almost 100 % of forest and land fires are caused by human. One of the purposes of this paper is to study the human activities that could trigger forest and peatland fires in OKI District. The results of this study are expected to produce information about the causes of fires and provide a scientific based information for policymakers to prevent forest and peatland fires in OKI District. This research was conducted in six villages in three sub-districts, Perigi and Riding Village in Pangkalan Lampam Sub-District; Ulak Depati and Jungkal Village in Pampangan Sub-District; and Pulu Beruang and Ujung Tanjung Village in Tulung Selapan Sub-District. This research method is field observations, interviews, and analyzing Terra/Aqua MODIS satellite imagery data to get the burned area. Based on the interview,it had been found that the main behavior of the community triggers peat fires is sonor, land preparation for plantation, and fishing. Terra/Aqua MODIS image analysis reveals that the area burned in 2015 and 2019, mostly occurred in swamp scrub and open land cover. The knowledge and perceptions of the people in OKI Regency on forest and peatland fire control are classified as moderate (56.7% - 83.3%). Community participation in outreach and training activities can increase people knowledge and perceptions on forest and peatland fire control. Public knowledge has an essential correlation with people's perceptions. Positive public perceptions on efforts to control fires will increase their participation. Community participation at the site level will determine the success of controlling forest and land fires.</em></p> <p><em>&nbsp;</em></p> Ati D Nurhayati, Bambang Hero Saharjo, Leti Sundawati, Syartinillia, Yeni Vetrita Copyright (c) 2020 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32725 Thu, 31 Dec 2020 00:00:00 +0700 Assessment of heavy metals pollution in sediment of Citarum River, Indonesia http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32238 <p><em>Heavy metals have been reported to accumulate in sediment of Citarum River. The measurement of total heavy metals may not be able to provide information about the exact dimension of pollution, thus the determination of different fractions assumed great importance. This study was performed to determine chemical fractions of heavy metals (Cu, Ni, Cr, Pb and Cd) in sediment collected at 8 locations from Citarum River. The sequential extraction procedure was used to extract heavy metals in water-soluble, acid-soluble, MnO occluded, organically bound, FeO occluded and residual fraction in sediment. Bioavailability and potential ecological risk level of heavy metals were evaluated based on bioavailability factor (BF) and risk assessment code (RAC) method. The results showed that Cu, Ni, Cr were mostly in residual form, indicate those from geological sources. Cu had low bioavailability and no risk in all sediment samples of Citarum River. Ni and Cr each was found to have risk at 2 locations. Pb and Cd were found dominantly in non-residual fraction, suggest those from anthropogenic sources. BF and RAC analysis of Pb and Cd suggest that there is a potential risk to the aquatic environment.</em></p> Mutia Oktarina Permai Yenny, Arief Hartono, Syaiful Anwar, Yumei Kang Copyright (c) 2020 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32238 Thu, 31 Dec 2020 00:00:00 +0700 Spatial mapping of soil erosion prediction through integration USLE model into Geography Information System http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32147 <p><em>The application of USLE model to several watersheds in Indonesia shows the diversity of processes that affect soil erosion. The integration of USLE model into Geography Information System (GIS) is able to provide a spatial distribution of soil erosion classes.&nbsp; This study aims to predict the soil erosion rate in various land cover in Ciesek sub watershed by integrating the USLE model into GIS. Undisturbed and disturbed soil sampling was carried out based on soil map unit, accompanied by observations of soil physic characteristics. Soil erosion prediction was done using the raster calculator with input raster-based data that has a certain spatial resolution. Analysis of the erosion class distribution on various land cover and slope classes was carried out by using the cross tabulation method. The results showed that the very low soil erosion class was dominant in the study location, namely in areas with forest land cover. The highest predicted of soil erosion rate resulted from bare land, followed by moorland and mix garden.</em></p> Sri Malahayati Yusuf, Kukuh Murtilaksono, Dwi Mei Lawaswati Copyright (c) 2020 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32147 Thu, 31 Dec 2020 00:00:00 +0700 Analysis of Blood Lead Levels on Street Vendors at Terminal Kampung Rambutan http://jma.journal.ipb.ac.id/index.php/jpsl/article/view/32841 <p><em>Emissions of motor vehicles containing heavy metals, one of which is lead (Pb).

Plastics have affinities with persistent organic pollutant such as PCB, DDT, PAH and phthalates that can damage the ecosystem as well as harm to human. In this study plastic wastes were collected using nets in seven stations along Baturusa watershed, sorted based on its composing resin (RIC), then measured the abundance and the density rate on each station. 36% of the collected plastic wastes are Polypropylene (02), and 24% are LDPE (04). The highest density rate of collected plastic wastes was found on Mabet river (1.36 x 102 items/m<sup>3</sup>), followed by Baturusa river, and Rangkui river estuary. These three stations are located near the settlements so that the source of the plastic wastes comes from domestic activities. The variety of waste management showed a significant impact to the amount of plastic wastes on waters. One of the plastic waste management for the settlements is to carry out 3R (reduce, reuse, recycle), such as waste bank programs and implement EPR (extended producer responsibility) programme.
