Prayitno MB, Dunand H, Sulistyani DP. 2019. The influence of urea fertilizer and zeolite minerals on carbon dioxide (Co2) emissions on the rice plant (Oryza Sativa L.) in peat soil. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 437-444. Palembang: Unsri Press. This study aims to determine the effect of nitrogen and zeolite fertilization on CO2 emissions in paddy rice plantation in peat soils. The study was conducted in the greenhouse of the Faculty of Agriculture, Sriwijaya University, Inderalaya, South Sumatra Province, from September to December 2018. The results of this study indicate that the treatment of nitrogen fertilizer produces the highest CO2 emissions in the production phase of the U3 treatment (average emissions: 3.80 mg/plant/day) and the lowest emissions in the vegetative phase (age 55 days) on the U2 treatment (average emissions: 2.41 mg/plant/day). The zeolite treatment produced the highest CO2 emissions in the production phase of Z1 treatment (average emission: 3.82 mg/plant/day) and the lowest emissions in the generative phase (age 65 days) on treatment Z1 (average emission: 2.43 mg/plant/day). The highest CO2 emission from the combination of nitrogen and zeolite fertilizers is in the rice production phase U2Z3 (3.95 mg/plant/day) and the lowest CO2 emission at 55 days on treatment U2Z1 (2.22 mg/plant/day).Keywords: peat soils, CO2 emissions, paddy rice, urea fertilizer, zeolite minerals

Prayitno et al, 2019.  The Effect of Ground Water Level and Nitrogen Fertilizers on the Plant Carbon Emission on Peat Soil. pp. 225-235.The aimed of study was to determine the increase of CO2 gas emissions in rice plants on peat soil which is influenced by ground water level and nitrogen fertilizer and to know the type of treatments that affects the highest CO2 gas emissions. The study was conducted at the green house, Faculty of Agriculture, Sriwijaya University, Inderalaya. The results showed that in the 5 cm water level from the soil surface and the application of nitrogen fertilizer of 250 kg/ha had significant effect on CO2 emission. The highest CO2 gas emissions during the growth period is generated by the water treatment of -5 cm from the soil surface and the application of nitrogen fertilizer of 250 kg/ha, about 2619.54 mg. The lowest CO2 emissions during the growth period were generated by the treatment of water level +5 cm from the soil surface and the application of fertilizer of 125 kg/ha, were about 348.30 mg. Total CO2 emissions during one growth period is 39699.15 mg. The results of this study can be as a recommendation for rice planting activities.

Abstract

Wulandari, A., & Prayitno, M.B. (2024). Estimation of 15-Year-Old Oil Palm (Elaeis Guineensis Jacq) Carbon Sequestration on Peatland at PT Waimusi Agroindah Afdeling XII, Kebun Sebubuk, Pedamaran Timur District, Ogan Komering Ilir Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 556–562).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One significant carbon storage area is in plant stands, which can be measured through plant biomass. The amount of carbon stored depends on the diversity and density of plants in an area, the type of soil present, and how it is managed. This research was carried out on oil palm plants on peatlands at PT Waimusi Agroindah, located in Afdeling XII, Kebun Sepucuk, East Pedamaran District, Ogan Komering Ilir Regency, South Sumatra, from September to October 2023. Estimating carbon tethering using carbon using the Non-destruction method by measuring the diameter of the rod with the formula W = 0.1208   and estimating plant carbon tethering. Measurements are made by measuring the diameter of the rod using a modification tool to measure the diameter of the rod. Samples were taken 3 different plots and with different areas but still in the same plant age, samples were taken as many as 18 points on each plot with the number of samples obtained as many as 54 samples. For oil palm plants, each plot with a plant age of 15 years has a diameter that is not too different. The results showed that oil palm plants with the highest average biomass value were found in plot 1 with a total carbon absorption of 21,338.75 tons  . Samples were taken in 3 different plots and with different areas but still in the same plant age, samples were taken as many as 18 points on each plot with the number of samples obtained as many as 54 samples. It is suspected that the biomass of carbon reserves and the amount of carbon tethering of oil palm plants planted on peatland at the plant age level is 15 years. For oil palm plants, each plot with a plant age of 15 years has a diameter that is not too different. The results of the study showed that oil palm plants with the highest average biomass value were found in plot 1 with a total carbon sequestration of 21,338.75 tons.
