“…Correlation analysis between SST and fish catches did not show a significant value in accordance with research conducted by Khan [15] in Eastern Indonesia. Chlorophyll increases with decreasing SST and decreases along with increasing SST value [15]. A high SST value will cause a decrease in the value of chlorophyll-a and a low SPL value will cause an increase in the value of chlorophyll-a.…”

“…The results of data analysis taken from satellite images show that the concentration of chlorophyll-a in Sunda Strait tends to increase along with the decrease in SST as well as the concentration of chlorophyll-a in eastern Indonesian sea [15]. Variation in chlorophyll-a concentration in the Sunda Strait is also caused by the influence of 2 characteristics of water masses from northern Java and the Indian Ocean.…”

“…Increasing phytoplankton is a sign of high water productivity, the upwelling process is always associated with an increase in phytoplankton abundance and water productivity followed by an increase in fish abundance in these waters and becomes the basis in estimating fishing areas. The relationship between chlorophyll and SST is inversely proportional [15]. An increased SST value causes a decrease in the value of chlorophyll-a and a decreased SST value will increase the value of chlorophyll-a.…”

Tembang is a pelagic fish which is important in Indonesia and the development on the Sunda Strait. The Indian Ocean Dipole could affect oceanography and at the same time will affect the population of fishes. The aim of this study was to determine the effect of IOD and oceanographic factors on the catch of Tembang fish. This research was conducted in the Sunda Strait waters by looking at the Dipole Mode Index (DMI) and oceanographic ocean conditions such as sea surface temperature and chlorophyll as well as the production of fish catches for 11 years from 2008-2018. IOD affects the catch of Tembang fish by 35.8%. Temperature influences the catch of Tembang fish in the Sunda Strait by 9.48%. Klorofil-a influences the catch of Tembang fish in Sunda Strait by 38.6%. DMI, Temperature, and Chlorophyll affect fish catches by 26.9%.

“…The productivity of existing coastal water, both old and new, needs to be increased by improving new environmentally friendly technologies. By increasing the productivity of coastal water, it is expected that the productivity of fishing activities to support the tourism business can increase so that people's income will increase (Chaverri, 1989;Kuralbayev, 2016;Anna et al, 2017;Khan et al, 2020).…”

One of the crucial coastal tourism is a region of Pangandaran District coastal tourism. The area represented a coastal region that has various exploiting characteristics and interconnected one another. The primary purpose of this research is to analyze the sustainable management policy strategy of coastal tourism. To reach the especial target, hence there are some activities which require to be conducted as a particular target that is (1) identifying determinant in the future, (2) determining strategic target and importance of the main stakeholder ; and (3) defining and describe of evolution possibility of future. The prospective analysis was conducted to yield a sustainable regional development scenario of coastal tourism in Pangandaran District, with determining key factors that affect system performance. From various possibilities that could happen, is formulated three regional development scenario of Pangandaran District coastal tourism to come, that are : 1) Conservative - Pessimistic by conducting to repair of main key factor only, 2) Moderate - Optimistic by conducting repair about 50 % of the primary key attribute (factor), 3) Progressive - Optimistic by conducting repair to entire key attribute (factor). To increase sustainable status forwards (long-period), a scenario that must be conducted to increase the regional sustainable development status of the coastal of Pangandaran District is Progressive – Optimistic by conducting repair by totally to all sensitive attribute so that all dimension become sustainable for coastal region development.

“…About 40% of the world's tuna catch comes from the use of FADs (Taquet 2013). The associative behavior of fish to approach floating objects encourages these objects to assist certain fishing activities (Matsumoto et al 2016;Rodriguez-Tress et al 2017;Khan et al 2020). Although they increase the productivity of fishing, FADs can have negative impacts if they're placed without proper supervision (Cheung et al 2009;Marshall et al 2009;Davies et al 2014).…”

Abstract. Hidayat R, Zainuddin M, Mallawa A, Mustapha MA, Putri ARS. 2021. Mapping spatial-temporal skipjack tuna habitat as a reference for Fish Aggregating Devices (FADs) settings in Makassar Strait, Indonesia. Biodiversitas 22: 3637-3647. Skipjack tuna (Katsuwonus pelamis) has a high economic value in the international market. Catching skipjack tuna using fish aggregating devices (FADs) without knowing its habitat characteristics can damage the ecosystem. This study aimed to determine suitable fishing areas for setting skipjack’s FADs. The data used included that on catch, sea surface temperature (SST), and sea surface chlorophyll-a (SSC) in the Makassar Strait obtained for 2017-2019. The generalized additive model (GAM) and empirical cumulative distribution function (ECDF) analyses were used to investigate the skipjack’s tuna habitat. A pelagic habitat index (PHI), with PHI > 75%, was applied to determine suitable FAD positions. The gravity center of the skipjack tuna habitat for ten months (January-October 2020) was calculated to validate the model’s results. The results showed that the optimum SST range was from 28.78°C to 31.25°C, while the SSC from 0.18 to 0.28 mg m-3. The best skipjack habitats in the southern Makassar Strait are criterion 4 (PHI > 90%) and criterion 3 (PHI = 85-90%), having a relatively high consistency of the average PHI values. These results can help determine the optimal positions for setting FADs to benefit the global management and sustainable development of skipjack tuna fisheries.
