Some Insight Into Direct Observation of Hydrological Parameters in Peatland Area of the South Sumatera

Abstract

An integrated observation system so-called SEnsory data transmission Service Assisted by Midori Engineering laboratory (SESAME) has been deployed in the peatland area of the South Sumatera Province, Indonesia since June 2017. The system directly measures and records the groundwater level, soil moisture, skin temperature and rainfall in the peatland area. In this study, we used data recorded at four locations, two sensors located at the Peatland Hydrological Unit (PHU) of the Saleh River and the other two are located at the PHU of the Lumpur River. Data for a period of 17 June 2017 to 31 March 2018 were used to evaluate the characteristics of hydrology and climatology of the peatland in the South Sumatera. It was found that a high rainfall is associated with low skin temperature, high soil moisture, and shallow groundwater level. Furthermore, it was found that the observed groundwater level is significantly correlated with the observed rainfall. Interestingly, the adjusted groundwater level from TRMM rainfall shows a significant correlation with the number of hotspots during dry-season (July-October). Therefore, we may use the observed rainfall for peat fire early morning.

The Impact of Positive Iod and La Niña on the Dynamics of Hydro-Climatological Parameters on Peatland

“…The data used in this research are hourly rainfall and hourly groundwater levels, obtained from the SESAME website at the following address: https://web.sesame-system.com. SESAME (Sensory Data Transmission Service Assisted by Midori Engineering Laboratory) is an in-situ integrated measurement system of several hydroclimatological parameters on peatlands in Indonesia, including in Kalimantan [16]. SESAME was built on the cooperation between the Indonesian government and the Japanese government.…”

“…The SESAME equipment system has been installed in Kalimantan since 2018, therefore the data used in this study is data from that year. The Peat and Mangrove Restoration Agency manage SESAME [16][17].…”

“…Research to determine the dynamics of these parameters during the extreme dry season and an extremely rainy season is very important as an effort to mitigate fire and flood disasters on these peatlands. Previous research has been conducted on the dynamics of these parameters in the South Sumatra region for 2019 [16][17]. This research was conducted in the Kalimantan region for three years, 2018, 2019, and 2020.…”

What are the dynamics of hydrometeorological parameters on peatlands during the 2019 extreme dry season?

“…SESAME was built on the cooperation between the Indonesian government and the Japanese government. SESAME is managed by an institution called the Peat Restoration Agency (BRG) [12]. The data of this research are data from measurement results at 2 BRG stations in West Kalimantan (WK) and in Central Kalimantan (CK).…”
