Abstract

The study conducted on 40 respondents who live in the vicinity of peatlands in limited production forest areas that were randomly selected from 9 villages that fall into 5 districts. The purpose of the study is to analyze the socio-economic conditions of society who live around peatlands limited production forest, describing the behavior of society in limited production forest, and identifies whether the socio-economic conditions affect the behavior of people in limited production forest. The study was designed to survey method, using a questionnaire to guide interviews with respondents. The results showed that the socio-economic conditions of society in limited production forest area is still relatively low in general source of livelihood is not fixed (the handyman, fishermen, farmers, firewood sellers, and so on), this is one that encourages people to use forests as Alternative increase family income. Behavior of communities around the limited production forest classified as positive, especially against the preservation of peatlands in limited production forest areas this is reflected by the observation in the field which show that most forest use as additional family pengahsilan limited to making materials for domestic industries (55%) , firewood (15%), and to farm is 30%. Basically as much as 90% of respondents stated concern for the preservation of peatlands in limited production forest.Key words: peatlands in the region HPT, perceptions, public behavior

Abstract

The research aimed to estimate biomass and carbon sequestration in unburned and post-burn peatlands. Data analysis was conducted from January 2023 to February 2023 in Sepucuk Agrosilvofishery Peatland Restoration demonstration plots, Ogan Komering Ilir, South Sumatra. The biomass and litter of understory vegetation were observed in good, medium, and poor vegetation conditions using the destructive method on 0.5 m x 0.5 m observation plots with 3 repetitions, and with 3 repetitions for each vegetation condition. The research depicts that post-burn peatland has a higher average carbon storage of understory vegetation and litter, 1.95 tons/ha for understory vegetation and 0.50 tons/ha for litter. However, unburned peatland has lower average carbon storage, 0.80 tons/ha for understory vegetation and 0.47 tons/ha for litter. The comparison depicts that Purun and Sembangun understory vegetation samples have significantly different results, while the vegetation litter samples have insignificantly different results.

Priatna SJ, Prayitno MB, 2022. Mapping of land suitability for developmentoil palm plants in experimental land Faculty of Agriculture location of Gelumbang. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 596-606. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Faculty of Agriculture, Sriwijaya University plans to carry out re-planting activities by converting rubber plants to oil palm. For this reason, information on soil fertility conditions and the level of suitability of the land if it is used as oil palm is needed. This study aims to determine the land suitability class (actual and potential) and the condition of soil fertility. This research was conducted using a detailed survey method, where the minimum distance for sampling is ±100 meters at a depth of 0 - 40 cm. While the evaluation of land suitability is carried out using the matching system method between the results of field observations and laboratory tests with the conditions for growing oil palm plants. The results showed that the experimental garden of FP Unsri Gelumbang had an actual suitability class which was classified as less suitable for planting oil palm (S3) with the main limiting factors being low nutrient availability (N, P & K), very acidic soil pH and low CEC value, However, potentially, if the limiting factor is improved, then the land can change its suitability class to Limited Suitability (S2) to Suitable (S1).

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.
