Abstract

Phenols play an important role in inhibiting the decomposition rate of peats. This research compares the total phenols, tannins, and colonies of phenol-degrading bacteria in natural and cultivated peatlands. The work was conducted from September to December 2023 on the peatlands in Pontianak, West Kalimantan. Samples of 60 cm3 were collected from the peat surface. The samples were taken from 4 types of peats, namely natural peats covered by ferns (A), cultivated peat with raised beds (B), cultivated peat with raised beds ameliorated with lime and beef manure (C), and cultivated peat with raised beds ameliorated with lime, beef manure, and Jadam fertilizer (D). The total phenols content was measured using the Folin-Ciocalteu 10% method using a UV-Vis spectrophotometer at a wavelength of 765 nm. The total tannins content was measured using the Folin-Denis method using a UV-Vis spectrophotometer at a wavelength of 740 nm. Total bacterial colonies were counted using the Total Plate Count method on selective Mineral Salt Medium (MSM) agar with the addition of phenol solution. The results showed that the average total phenols and tannins content values were generally low in the cultivated peats, particularly in the raised bed (B). The results indicate that the cultivated peat accelerates the activity of phenol-degrading bacteria. Keywords: Jadam fertilizer, phenols, phenol-degrading bacteria, peats, tannin

Abstract

The Indonesian government's peat restoration program, which began in 2016, is alleged to have an impact on the sustainability of peatland farming, because rewetting has the potential to cause waterlogging, limiting the crop commodities that can be cultivated. This project will look at the viability of small-scale farming on restored peatlands. To fulfill the study's objectives, we used a combination of quantitative and qualitative methods. The quantitative technique included an analysis of agricultural income to determine the economic sustainability, whereas the qualitative approach explains social sustainability. The environmental sustainability was assessed using the carbon rescue acquired after rewetting. The findings revealed that rewetting had little effect on the income from vegetable and fruit crops. The farming income, which remains relatively high, demonstrates that farming's economic sustainability is viable. Similarly, the social dimension does not detract from the sustainability aspect, because the rewetting of the land did not significantly alter the social structures and institutions that had been built in the farmer's community. Meanwhile, from an environmental standpoint, the impact of rewetting is quite favorable, as every 1 cm increase in water table level has the potential to conserve at least 0.71 tons of CO2 per acre per year, or around IDR 13,888−26,993. Keywords: carbon rescue, farming, peatland restoration, rewetting
