Patawari AMY, Anna Z, Hindayani P, Dhahiyat Y, Hasan Z, Putri IAP. 2022. Sustainability status of small-scale fisheries resources in Jakarta Bay, Indonesia after reclamation. Biodiversitas 23: 1715-1725. Reclamation in Jakarta Bay was initially implemented by constructing a giant 60 km long embankment in the area and 17 small islands in front of the coast of North Jakarta, but then it was stopped in 2018. After reclamation closures have affected fishery resources, especially small-scale ones that rely on catchment areas around the coastal waters of Jakarta Bay. To ensure the resource utilization level that meets the needs of the present and future generations, managing sustainably small-scale fish resources is crucial. This study aimed to analyze the sustainability status of small-scale fisheries in Jakarta Bay after reclamation. The results showed that efforts to manage small-scale fishery resources in the waters of Jakarta Bay-from the dimensions of fisheries, ecological, social, legal and institutional- are in unsustainable conditions. To improve the status, policy makers should consider 16 prioritized attributes on ecology, resource potential, economic, social, legal and institutional.

AbstractThe development ecotourism of Cirata reservoir has great potential in driving the economy building community welfare without having to sacrifice natural resources and damage the environment and even be sustainable. This study aims to determine the variables that influence the development of Cirata ecotourism and to determine the interdependence relationship between the variables so that it can be used as a policy for the sustainable development of Cirata ecotourism. The method used was Matrix Cross Impact Multiplication Applied to a Classification (MICMAC) structure analysis. The results showed that one driving variable is the conflict over the use of reservoirs, while the key variables are 21 of the 5 dimensions of sustainable development. A key variable in the environmental dimension, namely water quality; three key variables in the the economic dimension, namely tourism industry opportunities, economic development of local communities (MSMEs) and tourism funding allocations; two variables in the social dimension, namely the involvement of local communities, job opportunities in the tourism sector; the institutional dimension includes regulatory readiness in ecotourism development, local government support, community agreements and local rules, coordination and collaboration between institutions, and central government support; The dimensions of tourism included 10 variables, namely tourism activities, tourism management, uniqueness and beauty in tourist attractions, tourism facilities and infrastructure, cultural and natural tourist attractions, promotion and marketing strategies, tourism accommodation, tourism accessibility, potential local tourists, and potential foreign tourists. These variables become the initial foundation in determining policies and decisions by authorities in sustainable ecotourism management in the Cirata Reservoir

Hammerhead shark (Sphyrna lewini) population decline is a global problem experienced by various ocean basins worldwide, including Indramayu waters. As the regency known by its fishery barn that supplies 65% of captured fisheries in West Java, Indonesia, illegal fishing practices towards this protected species is inevitable. In 2017, 2869 tons of sharks were landed in Indramayu with the production value of IDR 44.01 billion, which hammerhead shark catch reaches 268 tons. This research aimed to observe the sustainability of hammerhead shark in Indramayu waters using a bio-economic model of Gordon Schaefer (GS) and Gompertz. The results showed the overfishing of hammerhead shark in Indramayu waters on actual conditions in 2012, 2014, 2015, 2016, 2017, and 2018, both in the GS and Gompertz models. The abundant number of hammerhead sharks started to deplete from 2015 to 2018, and the highest depletion was found in 2017, with a depletion value of 16 tons and depreciation value of IDR 164 million. The depletion rate suffered the most significant decline in 2011 to 2012 for all types of sharks, including hammerhead. The prohibition of consistent fishing and more pronounced law enforcement for hammered shark fishing are needed to maintain the sustainability of this resource.

The research was conducted in the area of the change of the Kamojang Nature Reserve (CA) to the Kamojang Nature Tourism Park (TWA) so that there was an increase in the area of the Kamojang Natural Tourism Park which was previously 535.01 Ha to 2,391 Ha. The goal of this study was to identify willingness to pay for environmental conservation in TWA after changes in land area. The method used willingness to pay (WTP) for environmental conservation in tourist areas in TWA Kamojang and the factors that influence the WTP value by using logit regression. The results showed that the average willingness to pay by visitors (WTP) is Rp. IDR 51,887 per visit with the option of improving facilities and infrastructure, adding tourist activities such as adequate camping grounds and hot springs and educational tourism of natural and environmental knowledge at TWA Kamojang. The total WTP is estimated to reach IDR 680,339,623 per year. All of the independent variables such as gender, age, income, education, travel costs during the tour affected the willingness to pay (WTP). The most significant factors influencing the willingness to pay for environmental conservation in the TWA Kamojang was age. The management of TWA Kamojang is expected to develop nature tourism that takes into account the principles of environmental conservation

Biodiversity ecosystem services are shared resources whose value can be measured through willingness to pay (WTP). This study aims to assess the willingness to pay of tourists for the conservation of biological resources in the UNESCO Global Geopark Ciletuh which is one of the leading tourist destinations in Indonesia. Furthermore, knowing how much visitors are willing to pay (WTP) for natural ecosystems can help policy makers manage biological resources and the environment which are the main foundation of sustainable nature-based tourism. The survey was conducted on 376 visiting tourists. The method used is a spatial assessment of the environmental ecosystem service approach, willingness to pay (WTP) for the uniqueness of biodiversity and factors that influence the WTP value using logit regression. The results of the mapping of ecosystem services supporting biodiversity show a very high-high category of 42,17% of the total area of the Ciletuh Geopark. The results also show that more than half of the respondents 68.8% are willing to pay for the conservation of biological resources in the Ciletuh Geopark. The average willingness to contribute to the general conservation fund is around $ 1.27 (Rp. 20,896). It was found that WTP for conservation was influenced by factors closely Introduction

The current trend in nature tourism has led to increased tourist visits to coastal areas, including destinations prone to disasters and previously exposed to tsunamis. This research, which aims to analyze the variables influencing tourists' desire to revisit disaster-prone areas, addresses a crucial and timely topic in tourism and disaster management. The research utilized a quantitative approach through a questionnaire-based survey of domestic tourists visiting the Pangandaran Beach Area in West Java, known for its susceptibility to tsunami disasters. The study involved 307 respondents who completed questionnaires between June and July 2023. Data analysis employed Partial Least Square – Structural Equation Model (PLS-SEM) analysis. The findings indicate a moderate level of association among the variables studied, with an R2 coefficient of 0.521. This suggests that destination image, risk perception, regional attractiveness, and knowledge of disaster risks collectively influence tourists' intentions to revisit. Notably, the variable "knowledge" did not significantly impact destination image and revisit intention but did influence risk perception. Additionally, risk perception was identified as a determinant influencing tourists' decisions to revisit Pangandaran. The research underscores the critical role of risk perception in influencing tourists' behavior in disaster-prone areas. This research highlights educating tourists about disaster risks and integrating individual factors in planning, as both influence revisits to disaster-prone destinations.
