Abstract

Laser technology has become one of the main innovations in material delivery, especially in the wood industry for cutting and engraving purposes. One of the advantages of this technology is the ability to produce precise and aesthetic patterns on the wood surface. However, each type of wood has unique characteristics to the heat treatment of the laser beam, so further research is needed to understand the specific response of each type of wood. This study aims to trigger the effect of variations in CO₂ laser power on changes in the surface color of cempaka wood (Michelia champaca) and to identify consumer preferences for the color results. The study was conducted at the Forest Products Technology Laboratory, University of Lampung, using three variations of laser power: 2.5 watts, 5 watts, and 7.5 watts, with each treatment repeated three times. The surface color was described using a CIE-Lab system-based colorimeter (parameters L*, a*, and b*) before and after engraving. In addition, a consumer preference survey was conducted boldly involving 100 students from the University of Lampung to assess the visualization of the engraving results. The results showed that higher laser power (7.5 watts) produced darker and more contrasting wood colors, with a decrease in L* values and an increase in a* and b* values. Most respondents preferred the results of engraving using 7.5 watts of power because it produced darker colors and was considered more aesthetic and gave sharper results.

Abstract

Social media has become a crucial platform for disseminating tourism-related information, including climbing tourism within conservation areas. Mount Gede Pangrango National Park (TNGGP) utilizes the Instagram account @bbtn_gn_gedepangrango to share information about hiking activities, promote nature-based tourism, and provide education on conservation ethics through the #PendakiCerdas campaign. This study aims to evaluate the management of the @bbtn_gn_gedepangrango account based on the socio-demographic characteristics of its followers. Data were collected from 482 active followers using a quantitative approach through an online questionnaire. The findings indicate that the majority of followers belong to Generation Z, are male, have a high school level of education, and reside in the Greater Jakarta area (Jabodetabek). However, the level of concern regarding waste management remains low, as only 19% of respondents demonstrated awareness of waste issues within TNGGP. These results highlight the need for more targeted and audience-specific conservation communication strategies to enhance public awareness and participation in environmental preservation efforts.

Abstract

The Gunung Botol Resort is a conservation area in West Java that is crucial for the protection of key wildlife such as the Javan leopard (Panthera pardus melas Cuvier, 1809). The presence of the Javan leopard plays a crucial role in the ecosystem. Data on its potential is essential for efforts to maintain the sustainability of its population in the ecosystem. This study aims to determine the presence of Javan leopard prey at the Gunung Botol Resort in the TNGHS. This study was conducted using camera traps. Analysis of the obtained photographic data was carried out using the Jim Sanderson application. The results of the study produced 133 images, there were 8 types of Javan leopard prey animals that were successfully caught by Camera traps, namely forest rats (Rattus sp) 27 images, barking deer (Muntiacus muntjak) 25 images, wild boar (Sus scrofa) 19 images, linsang (Prionodon linsang) 17 images, jungle cats (Prionaliurus bengalensis) 16 images, squirrels (Tupaia javanica) 16 images, skunk teludu (Mydaus javanica) 10 images and Javan barking quail (Arborophila javanica) 3 images. These results indicate the availability of diverse natural food for Javan leopards as top predators functioning as umbrella species. This finding is important to support ecological-based conservation strategies, especially in maintaining the stability of top predator populations through sustainable habitat management and food chains.

Abstract

Currently, attention is increasing on the management of border rivers, particularly in ASEAN member countries. A large portion of the border between Indonesia and Timor-Leste is river-bound, and communities are highly active in exploiting its potential. However, studies on river resource utilization in the border region between Indonesia and Timor-Leste are still very rare. Therefore, this study aims to analyze the relationship between community social characteristics, perceptions of river utilization, and analysis of the physical condition of the river. This research was conducted on the Motamasin River in Alas Selatan Village, on the Indonesia-Timor Leste border. A mixed methods approach was used, combining quantitative data in the form of social surveys and river discharge measurements with qualitative data from community perceptions through interviews and field observations. The results indicate that the majority of the community is of productive age and has a secondary or higher education level, which supports their understanding of the importance of sustainable water management. The Motamasin River is predominantly used for household and agricultural purposes, while fisheries use is still limited due to water quality degradation. The river's morphology exhibits intermittent characteristics with significant discharge fluctuations, ranging from 100 to 400 m³/s. These findings emphasize the importance of an interdisciplinary approach to water resource management that simultaneously considers social and physical aspects, especially in vulnerable border areas that have not been optimally served by national development policies.

Abstract

Ciremai Mountain National Park is a conservation area that has significant ecological and social value for the surrounding community. However, the types and amounts of benefits obtained by the community from the utilization of these forest resources are not yet known. This study aims to estimate the economic value and analyze the utilization of Ciremai Mountain National Park for optimal management. The methods used include interviews, observations, and literature studies. The results show that the economic value of natural resources from grass, firewood, nature tourism, and water utilization has a total economic value of IDR 5,575,068,353 per year in 2024. The majority of the community does not fully understand the existence and benefits of Ciremai Mountain National Park, but its existence is still considered important. This is because the national park provides natural resources whose benefits are directly felt by the community. It is recommended that the utilization of grass and firewood be carried out sustainably and that the management of natural resources and water utilization permits be based on carrying capacity with the socialization of forest conservation around water sources.

Abstract

The Thomas langur (Presbytis thomasi) is a primate endemic to Aceh, threatened with extinction due to hunting and habitat destruction. They are found not only in conservation areas but also in other areas and secondary forests. Mount Paroy is one of the important Thomas langur habitats that has been damaged due to encroachment by local communities. In this area, Thomas langur are often hunted because they are considered pests by farmers. The conservation status of Thomas langur is listed as Vulnerable by the IUCN and Appendix II by CITES. This habitat change has resulted in changes in the food supply pattern of Thomas langur. Food trees are replaced by plantation crops. Therefore, Thomas langur must be able to adapt to food sources and sleeping trees of non-forest species. This study aimed to determine the feeding behavior and adaptation of Thomas langur in disturbed secondary forests using exploratory survey methods and data collection techniques using line transect. Recorded data included the horizontal coordinates of the Thomas langur ' feeding points and the height of the trees used for feeding and resting. Data were analyzed using the Maximum Convex Polygon (MCV) method. Results obtained in the Mount Paroy habitat showed horizontal movement of 29 ha, and vertical space was used at altitudes below 10 m. For food, Thomas langur on Mount Paroy consumes more leaves.

Abstract

Bird migration is a natural phenomenon that plays a crucial role in maintaining global ecosystem balance. One of the most notable groups involved in this phenomenon is migratory waterbirds, which depend on wetlands as resting, feeding, and breeding sites during their migration period. This study aims to analyze the ecological indices of migratory birds, including species diversity, richness, evenness, abundance, and dominance, across various wetland types in Sumbernadi Village, South Lampung Regency. Data were collected from November to December 2024 using the point count method at six observation points representing four wetland types: mangrove, mudflat, fishpond, and rice field. The results recorded nine migratory bird species from three families, with the highest diversity observed in mudflats (H' = 1.958) and the lowest in mangroves (H' = 0.637). The Scolopacidae family dominated in terms of both abundance and distribution. Environmental factors, including food availability, vegetation structure, and human disturbance, influenced differences in diversity among habitats. These findings suggest that the wetlands in Sumbernadi Village provide vital ecological habitats for migratory birds. Therefore, sustainable management and conservation efforts are crucial for preserving the environmental functions of these wetlands and supporting the continuity of migratory bird populations in the region.
