Abstract

Identification of Subterranean Termite Infestation in Residential Areas in Bogor Regency, West Java. Subterranean termites are one of the pests that attack buildings. The interaction between termites and buildings significantly affects the durability, safety, and comfort of residential structures. This study aimed to identify the types of termites found in residential environments and determine the intensity of damage and frequency of termite attacks on pine wood (Pinus merkusii). Wood samples cut into 2 cm x 2 cm x 46 cm were conducted using the graveyard test for three months. The identified termite species was Macrotermes gilvus (M. Gilvus). The attack intensity obtained showed that 55% of the wood samples experienced damage due to subterranean termite attacks near the residential building, 30% remained unaffected, and 15% showed damage with penetration ranging from 3% to 75% of the cross-section. These results were reinforced by the high frequency of termite attacks on bait wood, which reached 70% (>40%). These findings are useful for homeowners if the area is later used for building construction. Therefore, preliminary measures are needed to address termite infestations in the area before using it for future building construction.

Abstract

This study evaluates the sound attenuation capabilities of four wood-based materials under realistic noise conditions. An experimental approach using a simple, non-standardized test method was conducted in a small-scale chamber, where each material was alternately installed as a barrier. Sound sources included motorcycle horns, falling objects, woodworking machines, and music. Sound intensity was measured using a sound level meter, and each treatment was repeated three times. The data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that all tested materials significantly reduced sound intensity compared to the control (P < 0.05), with the average sound intensity value ranging from 74.6 to 89.6 dB. Statistical analysis confirmed significant differences among materials. In conclusion, wood-based materials demonstrate the ability to reduce sound intensity under practical noise conditions, with particle board showing the best performance, and solid wood showing the lowest performance. Although the method used is simple and not based on standardized acoustic testing, the results provide preliminary evidence of the potential of porous wood-based materials as sound-absorbing media.
