Abstract

The Jambi Province has smallholder plantations established on peatlands, one of which is the local Betara variety of areca palm (pinang), known for its adaptability to high peat water table (TMAT) conditions. However, drainage remains necessary to prevent waterlogging. Peat decomposition releases carbon emissions, including dissolved organic carbon (DOC) into drainage water. The IPCC emphasizes the need for scientific data on carbon loss through DOC from tropical peatlands. This study was conducted in a Betara areca palm plantation located in Catur Rahayu Village, Dendang Subdistrict, Jambi, aiming to obtain quantitative data on DOC concentration in peatland drainage. TMAT observations and water sampling were carried out in a 100x100 m plot during the rainy season, coinciding with flooding in nearby areas. The results showed that the lowest TMAT reached -50 cm, consistently recorded at 20 observation points, indicating peat vulnerability even during the rainy season. No correlation was found between peat depth and TMAT. Groundwater from the peat flowed into a nearby tertiary canal connected to a secondary canal. The average DOC concentration at TMAT monitoring points was 3.321 mg/L, and in the tertiary canal, it was 3.309 mg/L. Keywords: Carbon; DOC; Drainage; IPCC; TMAT.ABSTRAKProvinsi Jambi memiliki perkebunan rakyat di lahan gambut, salah satunya adalah kebun pinang varietas lokal Betara yang adaptif terhadap kondisi tinggi muka air tanah (TMAT) gambut. Namun, drainase tetap diperlukan untuk mencegah genangan. Dekomposisi gambut menghasilkan emisi karbon, termasuk karbon terlarut (DOC) dalam air drainase. IPCC menekankan pentingnya data saintifik terkait kehilangan karbon melalui DOC dari lahan gambut tropis.Penelitian ini dilakukan di kebun pinang Desa Catur Rahayu, Kecamatan Dendang, Jambi, dengan tujuan memperoleh data kuantitatif konsentrasi DOC dari drainase gambut. Pengamatan TMAT dan pengambilan sampel air dilakukan di plot 100x100 m selama musim hujan, saat terjadi banjir di sekitar lokasi. Hasil penelitian menunjukkan TMAT terendah -50 cm, seragam di 20 titik pengamatan, menunjukkan kerentanan gambut meskipun saat musim hujan. Tidak ditemukan hubungan antara kedalaman gambut dan TMAT. Air tanah dari gambut mengalir ke kanal tersier terdekat yang terhubung ke kanal sekunder. Rata-rata konsentrasi DOC di titik TMAT adalah 3,321 mg/L dan di kanal tersier 3,309 mg/L.Kata kunci : Carbon; DOC; Drainase; IPCC; TMAT.

Abstract

Peat communities in Kepulauan Meranti face clean water scarcity and the lack of a national clean water supply system. We aim to observe local adaptation strategies in response to locally available water resources. We examined two villages (Lukun and Beting) and a city (Kota Selat Panjang), and ethnicities (indigenous Orang Akit, Malay, and Tionghoa) and problems concerning clean water scarcity. We conducted participatory observations and in-depth interviews for two months. We gathered data on water sources, perceptions regarding causes of water scarcity, and adaptation strategies. There are four local water sources. They are peat water (red water), borewell water (white water), rainwater, and packaged water. The perceived quality of these sources is influenced by environmental, religious, cultural, and economic values, affecting each ethnic group’s adaptation strategies. Rainwater is perceived as a clean source accessible to all, but differs in practices to access depending on economic condition. Peat water or rhedang water is perceived differently among the ethnic groups; Orang Akit relies on peat water and perceives it as freely available clean water. The Orang Akit demonstrated notable adaptability to peat water, but they are the most vulnerable community due to limited livelihood. The other two ethnic groups have more access to rainwater and perceive peat water as clean as rainwater. Adaptation to water scarcity in peatland differs in ethnic groups depending on their values and livelihoods.
