They have particular ways to find hunting spots and use hunting techniques. The research about this community was conducted in watershed of Mentarang, in order to determine the various kinds of games, frequently used hunting locations, and hunting ways of Dayak Lun Dayeh community. This study was carried out at two different times, on May–July 2016 and June–August 2021. Research data were collected through open-ended interviews (assisted by a key informant), field observation and photographic record. Data were presented descriptively by an ethnobiology approach. The results showed that this community practices subsistence hunting of games, which comprised mammals (69.73%), reptiles (14.15%), aves (8%), and amphibians (0.4%). The bush meat obtained from hunting was consumed as a protein source and served as a medium in traditional ceremonies or rel...

This research was conducted precisely on abandoned shrimp ponds in mangrove areas in the Mahakam Delta. Four different locations are locating on Sepatin ponds, ponds, ponds, and ponds Bayur headland. The purpose of this study was to estimate the above-ground carbon stock in abandoned shrimp ponds. Carbon stock measurement methods create a 125 m transect and quadrant divided into six plots at each location. These measurements were conducted on living vegetation and dead wood from felling vegetation. Measurement of above-ground biomass was done by measuring the tree diameter at breast height (1.3 m) on each tree diameter> 5 cm in radius quadrant plot 7 m. Vegetation has a diameter <5 cm categorized in seedling criteria and measured 30 cm from the ground within the quadrant plot radius of 2 m. The vegetation diversity experienced a success...
