Abstract

This study aims to investigate the relationship between household energy savings behaviors and governmental factors by implementing the theory of planned behavior (TPB). This cross-sectional study used a unique dataset compiled by Statistics Indonesia: Village Potential Statistics (VPS) Year 2011 and Environmental Care Behaviour Survey (ECBS) Year 2013. Variables connected to HES were decided by applying a logistic regression model with multivariable. Manual backward stepwise regression was performed. In the model, all variables of the planned behavior theory and its addition were significantly correlated with HES besides Intention (Very sincere: OR = 1.08, 95% CI: 0.99, 1.16). After examining the extension of five government-based variables, results of this study showed that intention, perceived behavioral control, attitude, and subjective norm might become the explanation of household energy savings

Abstract. Anggraini E, Purba H, Herlinda S, Susilawati, Lau WH, Arinafril A. 2026. Identification and inventory of bagworms on oil palm (Elaeis guineensis) in Sungai Rengit Village, Banyuasin District, South Sumatra, Indonesia. Asian J Agric 10 (1): g100128. https://doi.org/10.13057/asianjagric/g100128. Oil palm (Elaeis guineensis) is one of Indonesia’s most important plantation commodities and a major contributor to the national economy. However, productivity is often constrained by pest infestations, particularly bagworms (Lepidoptera: Psychidae), which damage palm fronds and reduce photosynthetic capacity. This study aimed to identify bagworm species and quantify their abundance and infestation intensity in oil palm plantations in Sungai Rengit Village, Banyuasin District, South Sumatra, to provide baseline information supporting the development of appropriate integrated pest management strategies. Field observations were conducted using a diagonal sampling method across five plots, with 20 trees observed per plot (100 trees in total). Bagworms were collected manually and identified based on morphological characteristics. Four species were recorded: Pteroma sp., Metisa plana, Pteroma pendula, and Mahasena corbetti. Pteroma sp. was the dominant species (912 individuals), whereas M. corbetti had the lowest abundance (137 individuals). The overall mean infestation intensity across the five plots was 62%, calculated using the Townsend-Heuberger index, indicating severe foliar damage. Higher infestation levels were observed in edge plots and areas exposed to greater sunlight. These findings indicate a high level of bagworm infestation in the study area and variation in abundance across plots, possibly influenced by microenvironmental factors. This study provides baseline information on bagworm species composition, abundance, and infestation intensity, which is important to support the implementation of appropriate integrated pest management strategies in oil palm plantations.
