Abstract

The Aopa Wetland Ecosystem, a Ramsar site, supports 1% of global species, including diverse waterbirds. However, populations are under serious threat from human activities, especially illegal hunting that disturbs habitats. The decline of waterbirds in Aopa Watumohai National Park (TNRAW) is the highest compared to other Indonesian national parks. This study, conducted from January to March 2023, aimed to analyze waterbird food resources through field observations. Data collected included distribution, number of species and individuals, diversity (Shannon index), and food types. Observations were carried out by boat across swamp areas. Results recorded 17 species of waterbirds totaling 1,217 individuals, with the highest abundance in open vegetation dominated by Irediparra galinacea (23.2%). Food resources were identified from 418 individuals representing 14 species, grouped into four classes: Insecta (5 species), Pisces (5), Gastropoda (3), and Malacostraca (1). The observation area was classified into vegetation types: open (VT), closed (VTP), and water body (BA). VT provided 14 food types, VTP 13 types, and BA 11 types. These findings emphasize the importance of protecting wetland habitats to sustain waterbird populations in TNRAW.

Abstract

Operational risk management is very important in maintaining the sustainability and success of the agro-tourism business. The research at Rizky Strawberry Sukabumi Agrotourism aims to identify and analyze the operational risks faced and evaluate the effectiveness of the risk management strategies implemented. The methodology uses a descriptive statistical approach and in-depth interviews to internal respondents using questionnaire guidance containing questions related to the implementation of risk management in Rizky Strawberry Agrotourism. The results of the analysis show ten types of operational risks that are grouped based on their causes: human resource risks (human resource competencies, relationships between employees, services, internal controls), system/regulatory risks (safety issues), facilities and infrastructure risks (management of tourist facilities, maintenance, public facilities, technology), environmental risks (pollution), and external risks (natural disasters). Of the ten risks, three are classified as very high, two high, two medium, and three low. The strategy is prioritized to minimize extreme and high risks to medium risk levels.

Abstract

Bali starling (Leucopsar rothschildi) is categorized as an endangered species based on IUCN, Appendix I based on CITES, and protected animals by the goverment of Indonesia. Bali Barat National Park (BBNP) has a breeding center for the recovery of species population in their natural habitat. The BBNP promoted soft release method for the introducing species in the wild habitat. This method consists of some treatments for supporting bali starling life and as consequently the distribution of species was concentrated in small area and the species can be monitored easily. This method has an effect the natural behaviour of bali starling is difficult to be formed and makes dependence on humans, and an effect on the shift of habitat choise by bali starling in BBNP. The problem is when the bali starling has been released to the wild. The number of individuals who have been released shows decrease fluctuation. This study was aimed to analyze potential of natural habitat. This study method using a vegetation analysis. The result found that the potential habitat with an importance value index is kemloko in the pole classification with a value 230.37% in the savanna ecosystem and talok with a value 86.27% in the monsoon forest ecosystem. The potential habitat in BBNP can still support the survival of bali straling.
