Abstract

One of the ameliorants that can be used to increase peat soil fertility is biochar. Biochar is a pyrolysis product, derived from burning biomass under conditions of limited or no oxygen. The aim of this experiment was to determine the characteristics of biochar from wood shavings (tatal) and coconut shells, which were heated at 350oC for 3 hours, 4 hours and 5 hours. From the analysis of lignin content, coconut shells are higher (45.20%) than tatal (25.74%), FITR Spectrophotometer results show that coconut shells pyrolyzed for 4 hours have fewer functional groups (8 types of functional groups with 3 aliphatic groups, 3 types aromatic group and 2 inorganic groups), compared to pyrolyzed tiles for 3 hours (9 groups and dominated by aromatic groups (5 types), then aliphatic groups (3 types) and inorganic groups (1 type)). Appearance of surface pores of 4 hour coconut shell biochar, with 1000x magnification, firm and regular in arrangement, macro and micro pore sizes smaller (3,677 µm; 3,688 µm; 5,091 µm) compared to pyrolyzed talc biochar for 3 hours (7,473 µm; 8,901 µm ). Coconut shell biochar has sturdy and neatly arranged pores, it is better as an ameliorant in peat soils compared to talc, because it can store carbon for a longer time. Tart has larger pores and collapses easily, so it rots easily.

Abstract

The utilization of land that is not aligned with its environmental carrying capacity is a significant issue in Indonesia. One affected sector is oil palm plantations, which covered an area of 16.38 million hectares in 2019. However, the government policy through Presidential Instruction Number 8 of 2018 halted this expansion. This policy also applies to independent farmers who must adhere to the principles and criteria of the RSPO (Roundtable on Sustainable Palm Oil), including practices to maintain soil fertility, control erosion and soil degradation, and plan development locations based on soil surveys. This study aims to evaluate the land capability of independent oil palm plantations in Sintang Regency. The methods used include soil surveys and land evaluation with the collection of soil morphology data and soil type classification. The study results show significant differences between the soil type map data issued by BBSDLP in 2010 and field verification results. Land evaluation identified four different soil units, each requiring specific management based on limiting factors such as plant root penetration, water excess, soil texture, slope gradient, and waterlogging. Proper land management includes soil and water conservation techniques, cover cropping, liming, and good drainage. Water management on peatlands must also consider environmental aspects to prevent ecosystem damage. With proper evaluation and management, land productivity can be sustainably increased.

Abstract

Channel bar has drawns public attention because the ownership of this channel bar is not yet defined. This research investigated the fluctuation of channel bar sizes between 1972 and 2022,, and addressed the potential of channel bar as a land bank. The research was conducted in Mempawah District, West Kalimantan Province. Landsat spatial data and aerial photographs of drone were used. A number of interviews were done to understand the potential of this channel bar as a land bank. Spatially and temporally, the channel bar in Mempawah District is fluctuated, with the current area of 646 ha. The dominant land cover of this channel bar is mangrove, which plays an important role in coastal abrasion prevention. Therefore, the use of channel bar as a land bank is potentially to protect mangrove, with fully participation of local communities. One of potential uses is to develop ecotourism, and designated a channel bar land bank for mangrove protection in the District spatial planning.
