Opis:
Peatland rehabilitation is an urgent need in order to minimize the effects of peat degradation and to support climate change mitigation. However, the rehabilitation of degraded peatlands still faces many obstacles. This study aimed to study the agroforestry system on peatlands applied by traditional communities as an effort to discover a peatland rehabilitation strategy. This research was conducted in the Pilang, Tanjung Taruna, and Kalampangan villages from February to August 2019. The data in this study were obtained through field observations, interviews with the community, and Focus Group Discussion. The data was then synthesized using descriptive statistics. The results of data analysis showed that in the study area, six types of agroforestry systems were found. Communities develop different agroforestry systems at various types of peat depths. Farmers develop vegetable and fruit-based agroforestry on shallow peat, rubber-based agroforestry, annual crops and fruit on medium peat, fruit and rubber forestry plants on deep peat. Most farmers planted endemic species including Rubber (Havea braziliensis), Galam (Melaleuca leucadendra) and Gerunggang (Cratoxylum arborescens). The results of this study can be adopted as a peatland rehabilitation strategy since they are in accordance with the socio-culture of the local community and capable to accommodate economic and conservation interests.

Opis:
In this paper, we describe the characterization and application of adsorbent derived from the pyrolysis of cocoa shells, which is a natural source of adsorbent materials. The adsorbent that was used in this experiment is an environmentally friendly adsorbent that was prepared by the pyrolysis of cocoa shells. For 1.5 hours, the pyrolysis process was carried out at temperatures ranging from 300 to 380 °C. The adsorbent was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and analysis with an X-ray diffraction (XRD) analyzer. Water-ash content and iodine absorption capacity were also determined in accordance with SNI 06-3730-1995. At a contact time of 90 minutes, the adsorption capacity of mercury ions was found to be 0.106 mg/gram. In this study, the adsorption of mercury ions with the adsorbent followed pseudo-second-order models with an R2 value of 0.9929.
