Abstract

Peat swamp area is an essential ecosystem due to high vulnerability of functions and services. As the change of forest cover in peat swamp area has increased considerably, many studies on peat swamp have focused on forest conversion or forest degradation. Meanwhile, in the context of changes in the forestlands are the sum of several processes such as deforestation, reforestation/afforestation, regeneration of previously deforested areas, and the changing spatial location of the forest boundary. Remote sensing technology seems to be a powerful tool to provide information required following that concerns. A comparison imagery taken at the different dates over the same locations for assessing those changes tends to be limited by the vegetation phenology and land-management practices. Consequently, the simultaneous analysis seems to be a way to deal with the issues above, as a means for better understanding of the dynamics changes in peat swamp area. In this study, we examined the feasibility of using MODIS images during the last 14 years for detecting and monitoring the changes in peat swamp area. We identified several significant patterns that have been assigned as the specific peat swamp ecosystem. The results indicate that a different type of ecosystem and its response to the environmental changes can be portrayed well by the significant patterns. In understanding the complex situations of each pattern, several vegetation dynamics patterns were characterized by physical land characteristics, such as peat depth, land use, concessions and others. Characterizing the pathways of dynamics change in peat swamp area will allow further identification for the range of proximate and underlying factors of the forest cover change that can help to develop useful policy interventions in peatland management.

Abstract

Increasing of economic development is generally followed by the change of landuse from agriculture to other function. If it occurs in large frequency and amount, it will threaten national food security. Therefore, it is necessary to monitor the agricultural land, especially paddy fields regarding to changes in landuse and global climate. Utilization and development of satellite technology is necessary to provide more accurate and independent database for agricultural land monitoring, especially paddy fields. This study aims to develop a utilization model for LAPAN-IPB satellite (LISAT) and other several satellites data that have been used for paddy field monitoring. This research is conducted through 2 stages: 1) Characterization LISAT satellite data to know spectral variation of paddy field, and 2) Development method of LISAT data fusion with other satellites for paddy field mapping. Based on the research results, the characteristics Red and NIR band in LISAT data imagery have a good correlation with Red and NIR band in LANDSAT 8 OLI data imagery, especially to detect paddy field in the vegetative phase, compared to other bands. Observation and measurement of spectral values using spectroradiometer need to be conducted periodically (starting from first planting season) to know the dynamics of the change related to the growth phase of paddy in paddy field. Pre-processing of image data needs to be conducted to obtain better LISAT data characterization results. Furthermore, it is necessary to develop appropriate algorithms or methods for geometric correction as well as atmospheric correction of LISAT data.

Abstract

Wildfires threaten the environment not only at local scales, but also at wider scales. Rapid monitoring system to detect active wildfires has been provided by satellite remote sensing technology, particularly through the advancement on thermal infrared sensors. However, satellite-based fire hotspots data, even at relatively high temporal resolution of less than one-day revisit period, such as time series of fire hotspots collected from TERRA and AQUA MODIS, do not tell exactly if they are fire ignitions or fire escapes, since other factors like wind, slope, and fuel biomass significantly drive the fire spread. Meanwhile, a number of biophysical fire simulation models have been developed, as tools to understand the roles of biophysical factors on the spread of wildfires.  Those models explicitly incorporate effects of slope, wind direction, wind speed, and vegetative fuel on the spreading rate of surface fire from the ignition points across a fuel bed, based on either field or laboratory experiments.  Nevertheless, none of those models have been implemented using real time fire data at relatively large extent areas. This study is aimed at incorporating spatially explicit time series data of weather (i.e. wind direction and wind speed), remotely sensed fuel biomass and remotely sensed fire hotspots, as well as incorporating more persistent biophysical factors (i.e. terrain), into an agent-based fire spread model, in order to identify fire ignitions within time series of remotely sensed fire hotspots.

Abstract

The Covid-19 pandemic has had a global impact on all sectors including the environment. 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.

Abstract

Citarum River is one of the strategically valuable rivers in Indonesia, especially on Java Island. Since 2018, the central government has carried out the "Citarum Harum" program to revitalize the river while improving its reputation of Citarum as one of the dirtiest rivers in the world. This study aimed to see the pollution load capacity of the downstream Citarum River 4 years after the revitalization program was implemented. Downstream Citarum Watershed (Karawang Regency) was chosen as the focus of the study site because of the very high risk of contamination. This research was comparing the pollution load capacity of biochemical oxygen demand (BOD) in 2022 using Qual2Kw software and 2017 based on the data analyzed by the Ministry of Environment and Forestry. River revitalization over the last 4 years has significantly reduced the BOD value in the downstream Citarum Watershed. The success of this revitalization program can be a reference for other watershed management toward environmental improvement using the same scheme. This study is expected to provide updated information on water quality in the downstream Citarum watershed several years after revitalization and provide an overview of the important functions of river revitalization

Abstract

Rivers have the potential for enormous flows of water, nutrients, and food that can create habitats for various living creatures. However, the flow of pollutants into estuaries and coastal areas can degrade environmental conditions in downstream areas of the river. Numerous studies have highlighted the loss of aquatic species due to increased stressors and pollutants in heavily contaminated rivers. This manuscript aims to analyze the phytoplankton diversity in three stations (natural riparian, concreted riparian, and estuary) of the Ciliwung River in Jakarta. Using environmental DNA (eDNA), we identified and compared the number of phytoplankton families and read sequences with various water quality parameters. The results showed that each station consists of 16, 13, and 20 families with 11,257; 75,963; and 37,339 read sequences, respectively. The study showed that phytoplankton family diversity in Stations 1 and 2 correlates with water pollution levels (lightly to extremely polluted). In contrast, Station 3 exhibited an unusual pattern, with high family diversity despite declining water quality.

Abstract

High anthropogenic activities have an impact on land use change that threatens lake ecosystems in various parts of the world. The socio-economic condition of the local community is one of the main factors affecting land use on the lakeshores. Government policies related to lake protection are important in the lake ecosystems management, especially land use in the lakeshore zones. This paper aimed to investigate lake management in agricultural areas in various countries such as Poland, China, and Indonesia. By conducting this comparison, management of the lake ecosystems including the land use of the surrounding area have been discovered. Through case study analysis and policy analysis issued by the central government, the positive and negative effects of each policy related to lake management could be obtained. The results showed that in several European countries, the trend of lakes utilization for tourism areas is increasing. China, a country with rapid economic growth, has begun to restore agricultural land into wetlands and lake ecosystem. Meanwhile, the high demand for food in Indonesia causes agricultural areas in the lakeshore zones difficult to convert.
