Abstract

Biological activity of termites consistently generates various biogenic products depend of the type of food sources. Furthermore, the biogenic product is believed to have an important role in the improvement of soil physical and chemical properties. The purpose of this study is to determine the structure and chemical properties of biogenic products resulted from the activity of termites Schedorhinotermes spp. using newsprint paper and tofu processing wastes as food sources. Newsprint paper waste was mixed with tofu processing wastes water at a different levels, i.e. 10 %, 20 %, and 30 % (w/v) for the objective of study. Each of the mixture with weight of 18,8 g equivalent to oven dry weight was then placed in the sample container unit size 6 x 6 cm, placed at about 3 cm underground with the indicated of termite Schedorhinotermes spp activity, and covered by PVC stopper. The testing unit were left in place for about 6 weeks to allow the termite attacks. The attacked sample unit were then analyzed for their structure and chemical properties including bulk density, aggregate fraction distribution, pH, C-organic content. The soil around the sample unit were took using a 7 cm diameter ground ring to be used as a reference or comparison with biogenic structures formed by termites. The result showed that the biogenic products have better structure and chemical compared to the its surrounding soil.

Abstract

Rhinotermitidae is a family with many species which are pests to plants and buildings. This study aims to identify the species belonging to the Rhinotermitidae. The morphological characteristics of specimens collected by using the transect sampling protocol of forest types (natural forest, pine plantation, and mahogany plantation) in the Educational Forest were observed. The results showed that the number of termite specimens differed from each forest type, namely 36.4% obtained in natural forests, 38.4% in mahogany plantations, and 25.2% in pine plantations. The total of collected termites was 258 specimens, mostly members of Termitidae (67.4%) and others including members of Rhinotermitidae (32.6%). Based on morphological characteristics of the soldier of Rhinotermitidae, only two species were identified, namely Coptotermes curvignathus (Coptotermitinae) and Schedorhinotermes sp. (Rhinotermitinae) with a predominance of 88.5%.
