Abstract

The Sumatran Chestnut-necklaced Partridge Tropicoperdix charltonii atjenensis is a subspecies endemic to the lowland forests of Aceh and Lampung, Sumatra. This study used the Analytical Hierarchy Process (AHP) to identify suitable habitats for this subspecies, considering environmental variables such as elevation, tree cover, slope, distance to water sources, and anthropogenic factors. Data collection and spatial analysis were conducted from July 22 to August 23, 2023. The AHP analysis revealed that T. c. atjenensis is typically found in lowland habitats with specific characteristics: average elevation of 130 meters, proximity to water sources, and very dense forest cover (93%). Additionally, suitable habitats tend to be far from road access (average distance of 1.7 km) and residential settlements (average distance of 5.3 km). The resulting distribution map highlights the importance of well-preserved, forested areas as primary habitats for this subspecies.

Abstract

Transportation plays a very important role in economic development in Indonesia. The contribution of construction services to national development is very large, especially in preparing road facilities and infrastructure which have a great influence on economic development in Indonesia. In order to integrate the transportation system in Indonesia, this indicates the increasing number of road maintenance project activities. Jambi Province has a national road where road maintenance activities are carried out every year. The increasing number of road maintenance activities means that based on existing regulations, it is important to carry out environmental testing during the construction period. The purpose of this study is to carry out environmental testing on the Preservation work of the X road section which includes surface water analysis, ambient air testing, n. The method used in this study is descriptive quantitative, the quality standards in this test include Government Regulation No. 22 of 2021. The results of this study at the location obtained all test results with the nationally accredited laboratory KAN are still below the environmental quality standard parameters.

Abstract

Post-pandemic tourism is characterized by increasing behavioral heterogeneity as digital technologies reshape travel planning and mobility practices, challenging traditional demographic-based segmentation. This study develops a techno-behavioral, data-driven segmentation framework within the Smart Tourism Ecosystem perspective by conceptualizing digital adoption as a mediating mechanism between socio-demographic attributes and travel behavior. Using survey data from 805 domestic tourists in Yogyakarta, Indonesia, TwoStep Cluster Analysis (log-likelihood distance; BIC-based cluster selection) identifies two distinct segments: Digital Leisure Travelers (DLT) and Budget-Conscious Digital Natives (BDN). The clustering solution demonstrates fair quality (Silhouette = 0.32). Predictor-importance and validation tests indicate that income, education, generational cohort, and digital application use are the strongest discriminators, while itinerary intensity differs significantly between clusters (p < 0.001; η² = 0.10). The findings highlight that widespread digital engagement produces differentiated mobility outcomes shaped by socio-economic capacity, emphasizing the need for segment-sensitive and inclusive smart tourism strategies.
