Abstract

In South Kalimantan, peat water is the main water sources for local people. But peat water has high iron content. It cannot be consumed directly and need further treatment. Adsorption is the most common technology to treat peat water. The goal of this research is to study sago waste adsorbent for iron removal in peat water. Citric acid was employed as activating agent in the sago waste activated carbon adsorbent fabrication. Carbonization process was done at 300 ℃ with 70, 80, 90, 100, 110 and 120 minutes of time variation. After treatment using the adsorbent, iron content was tested via Atomic Absorption Spectrophotometry (AAS). While, Fourier Transform Infra-Red (FTIR) were carried out to investigate the functional groups of sago pith waste activated carbon (SPWAC) and sago pith waste unactivated carbon (SPWUC). The experiment results show iron could be removed until 82% with iron concentration of 0.05 mg/l at 80 minutes. SPWAC and SPWUC have functional groups such as alkenes (C-H and C=C), carbonyl (C=O and C-O) and hydroxyl (O-H). Fe concentrations are still meet water quality standard according to No. 492/Menkes/PER/IV/2010 which is 0.3 mg/L. Therefore, adsorption uses sago pith waste activated carbon is an effective and inexpensive water treatment.

Abstract

The biophysical model of Mount Babaris aims to predict carbon potential using remote sensing technology to address high levels of greenhouse gases, particularly CO2. This study combines satellite data with field measurements to create a validated model analyzing Forest Canopy Height (FCH), Normalized Difference Vegetation Index (NDVI), Vegetation Density (VD), and Land Surface Temperature (LST). A multiple regression analysis shows a strong correlation between these parameters and VD, with an R² value of 0.8673, indicating that 86.73% of the variation in vegetation density can be explained by these variables. Field validation, including drone photographs, crown and stem base density measurements, and plant size, ensures the accuracy of the satellite-derived data. The model uses the equation VD = 123.295486 x NDVI - 0.413961 x LST - 0.410253 x FCH - 3.173195, validated through field data. For processing field measurements, the equation LBDstemCor = 0.007645 x LBDcrown + 0.034348 x VD - 1.575439, with an R² value of 0.9564, further demonstrates its accuracy. To estimate carbon potential in kilograms per pixel (CPP), the equation CPP = LBDstemCor x FCHcor x 0.7 x 680 x 1.34 x 0.47 was used. The predicted carbon potential for Mount Babaris (1,576 ha) ranges from 607,767.55 to 607,829.54 tons, reflecting the model's precision in estimating carbon storage. This model plays a crucial role in monitoring and predicting carbon potential, supporting environmental management and climate change mitigation efforts. By integrating GIS and remote sensing, the model offers a scalable, replicable methodology adaptable to other regions with similar characteristics. It enhances the accuracy of carbon stock estimations and provides essential data for developing strategies to increase carbon sequestration, contributing to global climate change mitigation. The combination of satellite data, field measurements, and statistical analysis makes this model an invaluable tool for effective ecosystem conservation and restoration.
