South Kalimantan (Indonesia) | Sustainable peatland management: case study of rubber and intercrops in Jabiren Village | Pulang Pisau Regency | Pengelolaan lahan gambut berkelanjutan: studi kasus pengembangan karet dan tanaman sela di Desa Jabiren, Kabupaten Pulang Pisau, Kalimantan Tengah

Utilization of peat for the rubber plants have been carried out by people in Central Kalimantan. Upon the occurrence of large-scale forest and peat fires, peat utilization for rubber trees increasing, especially in the former area of the fire. ICCTF Demonstration plots in the Jabiren Village, Jabiren Raya District, Pulang Pisau Regency, Central Kalimantan was the area of the former peat fires region in 2005. Location was a peatland with the criteria in the thickness is very deep, between 5 to 7 meters, and level of maturity varies between hemic and sapric. Rubber derived from the seeds (GT-1) were planted in 2006. The purpose of this study was to determine the effect of material amelioration (pugam A, pugam T, chicken manure, soil mineral and control) of the agronomic characteristics of rubber plants and between plants that have been implemented during the one year of the study, from January 2011 - March 2012. Each treatment plot had a size of 35 m x 180 m consisted of seven rubber aisle with rubber planting distance 3 m x 5 m. Planting carried out in the aisle between the rows of rubber trees (width 5 m), namely for rice, corn was replaced, and the last pineapple. The results showed that the rubber stem circumference increment for a period of one year is about 10 cm is obtained at Pugam T treatment, and control, and Pugam A, while in chicken manure treatment of about 8.45 cm, and mineral land treatment amounted to only 7.17 cm. Utilization aisle between rows of rubber age 5 years showed that the response of the pineapple plant was more able to adapt (grow well) compared to rice and corn. Based on the agronomic parameters of high accretion pineapple plant showed that after 6 months of planting, the treatment pugam A was the highest reached 30.7 cm, while based on the parameter increment width and number of leaf canopy, chicken manure treatment was the highest, reaching respectively 82.8 cm and 10 strands. Plant development of rice or corn crops as the intercropping crops could not produce at the age of 5 year rubber, while the development of the pineapple plant looked quite able to adapt to the shade of the canopy of rubber.
