“…Furthermore, the groundwater level formed the dome shape (Figure 3). These findings confirmed the previous studies by Aswandi, Sadono, Supriyo, and Hartono (2016) and (Wakhid, Nurzakiah, and Zainudin, 2019) which reported a similar phenomenon. It has been suggested that the phenomenon seems due to water nature, which flows to a -197,4 -191,4 -178,6 -152,8 -196 Typically, groundwater level should be maintained on below the roots zone, in order to provide adequate water content and air, by controlling water level in tertiary channels (Wangsadipura, 2005).…”

Degraded peatlands typically have been cultivated by communities for agriculture. Ex ICCTF plot in Jabiren is considered as a degraded peatland since the area has been cultivated and drained for smallholder plantation. This study aimed to characterise the groundwater level and peat subsidence periodically over seven months of observation. It has been found that the groundwater level fluctuated from 50 cm to 150 cm below the peat surface, implying the deterioration of peat ecosystem. Based on the transect observation, the groundwater table seems to form a dome shape with the deeper level existed adjacent to the canal. The average peat subsidence was around 27 to 39 cm in cumulative since the subsidence stick installation. However, in the range of ten-month of observation, the peat subsidence was around 8.5 cm. The subsidence was higher on the location adjacent to the canal (25 m) compared to the farther one (100 m). The subsidence also fluctuated, notably in the wet season, indicating the influence of rain event to peat subsidence. Rewetting peatland was likely to result in reducing peat subsidence suggesting the importance of water management in peatland to recover degraded peatland.

“…Hasil penelitian ini sama dengan hasil penelitian yang dilakukan oleh Wakhid et al (2019) yang melaporkan bahwa tinggi muka air di lahan gambut dekat saluran lebih dalam dibanding tinggi muka air lahan yang jauh dari saluran. Tinggi muka air tanah pada gambut ditentukan jarak titik pengamatan dari saluran drainase (Adji et al, 2019).…”

“…Tinggi muka air tanah pada gambut ditentukan jarak titik pengamatan dari saluran drainase (Adji et al, 2019). Wakhid et al (2019) mengemukakan bahwa hal ini terjadi karena sifat air yang selalu mengalir ke tempat yang lebih rendah. Hasil penelitian ini mengindikasikan perlunya pengaturan dalam pembuatan saluran di lahan gambut untuk menjaga penurunan tinggi muka air di lahan gambut yang drastis.…”

Kemampuan gambut dalam menyerap air mempunyai arti penting bagi pengelolaan lahan gambut yang sering digambarkan dengan kurva retensi air menurut fungsi potensial air. Penelitian ini dirancang untuk memahami hubungan antara tinggi muka air dengan kadar lengas tanah gambut. Data tinggi muka air tanah (TMA) yang diperoleh melalui pengukuran langsung di lapangan. Data kadar lengas ditetapkan di laboratorium. Data kadar seratnya dianalisis secara kuantitatif dengan bentuk diagram menurut tipe penggunaan lahan dan tingkat kematangan gambutnya. Hasil penelitian ini mengindikasikan bahwa semakin tinggi muka air gambut semakin jauh dari permukaan tanah diikuti semakin tinggi kadar lengas gambut pada lahan terbuka. Hasil penelitian menunjukkan hasil yang kontradiktif dengan penelitian lain. Hal ini menunjukkan bahwa kadar lengas gambut tidak semata dipengaruhi oleh TMA, karena dapat terkait dengan daya kapilaritas atau ada faktor lain yang mungkin berpengaruh lebih dominan terhadap perubahan kadar lengas gambut

“…Walaupun musim kemarau pada tahun 2014 lebih panjang dibandingkan musim kemarau tahun 2015, tetapi TMA terendah tetap terjadi pada tahun 2015 (Itoh et al, 2017). Dibandingkan dengan TMA yang terukur tahun 2014 pada lahan gambut yang terbakar sekitar 1 km dari plot penelitian, selisih TMA terdalam mencapai 36 cm, dimana TMA terdalam di lahan tersebut hanya -135 cm, dengan rata-rata -83 cm (Wakhid et al, 2016). Begitu juga dengan TMA tahun 2014 di hutan yang telah didrainase di Palangkaraya, selisih terdalam TMA sekitar 32 cm, dengan rata-rata TMA -55 cm (Itoh et al, 2017).…”

Water level (TMA) and soil temperature are two keys of environmental factors for ecosystem peatland study and for peatland ecosystem sustainability as well as crop productivity on peatland. On the other hand, climate change is another factor that cannot be avoided and affects the peatland ecosystem. Fluctuation of water level and soil temperature more severe on El Niño or dry years. Therefore, monitoring of water level and soil temperature on peatland ecosystem is important for sustainable peat management, especially on the dry years. The study objective was to determine the dynamics of water level and soil temperature on peatlands ecosystem in El Niño years and compare them to the normal year conditions. Water level and soil temperature were conducted automatically on rubber plantations on tropical peatland in Jabiren, Pulang Pisau, Central Kalimantan, from January to December 2015. Water level on the field and canal drainage on tropical peatlands followed the variations of precipitation. Although the average of annual precipitation on El Niño year is almost the same as normal year, but the water level and soil temperature show quite significant differences to the normal years. In addition, even water level was deeper and soil temperature is quite high in the dry season of El Niño years, but this field did not burn because productive plants were growth managed well by the owner.
