- ABSTRACT This paper is part two of the overall rainfall interception studies carried out in the tropical rainfall of Central Kalimantan. Part one was the same rainfall interception study conducted in an unlogged forest area. The following a result of rainfall interception loss study carried out in logged-over forest area. Rainfall interception losses were monitored for eight months and related to vegetation and rainfall characteristics at the BPK-ODA research site in the upper stream Mentaya river, Central Kalimantan. The rainfall interception loss were quantified bared on the records of 74 selected rainfall events within the range of 5.0 to 171.3 mm. Over eight months in one hectare of lagged-oper forest area 172,2 mm (6.4%) of 2682 mrn gross rainfall occuring in the research area was "loss" to the atmosphere. This is a reduction of about 5% compared to that from. the unlogged forest area. Canopy throughfill equaled 2503 mm (93%) ofgross rainfall whereas stemfiow represented 6.8 mm (0.25%). Compared to that of the unlogged forest, overall canopy throughfiall in logged-over area was greater, while stentflow value was much smaller, reduced from L3 to 0.25% of the incident gross rainfidl. Unfortunately, there is no rainfall interception data from logged-over area found in other tropical rainforest environment, and therefore, proper comparation and discussion can not be made. Kata Kunci.: rainfall - logged ever - central Kalimantan - forest area
