EVALUASI MULTITEMPORAL INDEKS KESEHATAN KARANG DI KAWASAN KONSERVASI PULAU PIEH DAN LAUT SEKITARNYA (2021-2024): ANALISIS BIOFISIK DAN IMPLIKASINYA TERHADAP PENGELOLAAN BERBASIS EKOSISTEM
No full textTerumbu karang merupakan ekosistem laut yang memiliki peran penting dalam menjaga biodiversitas dan ketahanan lingkungan pesisir. Namun, dalam beberapa dekade terakhir, degradasi terumbu karang terus meningkat akibat aktivitas antropogenik dan perubahan iklim. Penelitian ini bertujuan untuk menganalisis Indeks Kesehatan Karang (Coral Health Index / CHI) di Kawasan Konservasi Pulau Pieh dan perairan sekitarnya dalam periode 2021-2024 menggunakan pendekatan biofisik dan statistik. Analisis dilakukan terhadap 16 stasiun pengamatan, menggunakan data parameter bentik (tutupan karang hidup, resiliensi) dan biomassa ikan karang yang diperoleh melalui metode Underwater Photo Transect (UPT) dan Underwater Visual Census (UVC). Hasil penelitian menunjukkan bahwa nilai CHI berkisar antara 3 hingga 10, dengan beberapa stasiun menunjukkan tren peningkatan sementara lainnya mengalami stagnasi atau penurunan. Analisis Spearman correlation mengindikasikan bahwa parameter kualitas air (pH, DO, suhu, dan salinitas) tidak memiliki hubungan signifikan terhadap CHI pada semua tahun pengamatan (p-value > 0,05). Analisis Principal Component Analysis (PCA) menunjukkan bahwa faktor kualitas air bukan penentu utama perubahan CHI, tetapi tekanan ekologis dan aktivitas antropogenik lebih berperan dalam menentukan kondisi kesehatan terumbu karang. Hasil penelitian ini memberikan rekomendasi untuk pengelolaan berbasis ekosistem guna menjaga keberlanjutan ekosistem terumbu karang.Coral reefs are marine ecosystems that play a crucial role in maintaining biodiversity and coastal environmental resilience. However, in recent decades, coral reef degradation has continued to increase due to anthropogenic activities and climate change. This study aims to analyze the Coral Health Index (CHI) in the Pieh Island Conservation Area and its surrounding waters from 2021 to 2024 using biophysical and statistical approaches. The analysis was conducted at 16 observation stations using benthic parameters (live coral cover, resilience) and reef fish biomass data collected through the Underwater Photo Transect (UPT) and Underwater Visual Census (UVC) methods. The results indicate that CHI values range from 3 to 10, with some stations showing an increasing trend while others experience stagnation or decline. Spearman correlation analysis indicates that water quality parameters (pH, DO, temperature, and salinity) do not have a significant relationship with CHI in all observation years (p-value > 0.05). Principal Component Analysis (PCA) shows that water quality factors are not the main determinants of CHI changes; instead, ecological pressure and anthropogenic activities play a more significant role in determining coral reef health. This study provides recommendations for ecosystem-based management to ensure the sustainability of coral reef ecosystems
Estimating the Size of Sailfin Catfish (Pterigoplichthys sp) at First Gonad Maturity in Sidenreng Lake, South Sulawesi, Indonesia
Get PDFThe invasion of the sailfin catfish (Pterygoplichthys sp.) in Lake Sidenreng has caused serious ecological disruption and threatens the sustainability of local fishery resources that support the livelihoods of surrounding communities. This study aimed to analyze the reproductive aspects of female sailfin catfish as a basis for population control efforts, by estimating the fork length at first gonadal maturity (Lm₅₀) and calculating the gonadosomatic index (GSI). A total of 164 female sailfin catfish were collected using gill nets from various sampling sites and analyzed at the Basic Laboratory of the Faculty of Science and Technology. GSI analysis showed values ranging from 0.28% to 15.09%, with an average of 4.29%. Most individuals were found at gonadal maturity stage IV, indicating a high reproductive readiness. The estimated Lm₅₀ was 214.12 mm, suggesting that these fish are capable of reproducing at a relatively small body size. These findings reveal a high reproductive potential, which may accelerate the invasion rate of this species in Lake Sidenreng. Information on reproductive characteristics is essential as a foundation for formulating management strategies to suppress population growth and support the sustainability of the aquatic ecosystem
MORPHOREGRESSION AND CONDITION OF FRIGATE TUNA (Auxis thazard LACEPÈDE, 1800) IN SOUTH COAST OF BALI STRAIT WATERS
Get PDFBali Strait water has contributed to the production of pelagic capture fisheries in FMA-573. The potential for fisheries in the Bali Strait is very diverse, especially small pelagic fish such as frigate tuna, bullet tuna, bali sardinella, scad fish and mackerel. Frigate tuna (Auxis thazard) is a pelagic fish from the Scombridae family. This fish can be found in tropical and subtropical waters. Information regarding frigate tuna on the southern coast of the Bali Strait has yet to be found to date. This research aims to reveal morphoregression, which includes the length-length relationship and growth patterns, as well as the condition of frigate tuna in the southern coastal waters of the Bali Strait for ecosystem-based fisheries management. Sampling of frigate tuna was carried out from February to July 2024. Fish samples were taken from traditional fishermen who used gill nets as fishing gear in the southern coastal waters of the Bali Strait. Each fish sample was measured for total length, fork length, and standard length and weighed to analyze the length-length relationship, growth patterns, and condition factors. The number of frigate tuna caught during the research was 356. The total length of the samples caught ranged from 274 – 416 mm, weighing 270.3 – 972.4 grams. Each character of the length of the frigate tuna has a close relationship. The fork length character is the most precise in estimating fish weight, so the fork length character is used to analyze the length-weight relationship. The growth pattern of frigate tuna is positive allometric with good conditions. The results of this research can be used as a basis for ecosystem-based management of tuna fisheries
Effect of Bacteriophage Therapy on the Hemocyte Profile of Whiteleg Shrimp (Litopenaeus vannamei) Infected with Acute Hepatopancreatic Necrosis Disease
No full textAcute Hepatopancreatic Necrosis Disease (AHPND), caused by Vibrio parahaemolyticus, poses a major threat to the cultivation of Pacific white shrimp (Litopenaeus vannamei) due to its high mortality rate. This study aimed to evaluate the effectiveness of bacteriophage therapy on the non-specific immune response of shrimp, assessed through Differential Hemocyte Count (DHC) analysis. The research was conducted over six months using a Completely Randomized Design with seven treatment groups, including positive control (KP), negative control (KN), antibiotic treatment (KA), and three bacteriophage dosages: 10⁷ PFU/mL (FB7), 10⁸ PFU/mL (FB8), and 10⁹ PFU/mL (FB9), all challenged with V. parahaemolyticus at 10⁵ CFU/mL. DHC observations were carried out on days 0, 1, 3, and 7 post-treatment. The results indicated that the bacteriophage-treated group, particularly FB9 (10⁹ PFU/mL), maintained a hyaline cell proportion of 50–57% through day 7, similar to the immune profile of the negative control. In contrast, the positive control exhibited a marked decrease in hyaline cells and an increase in granular cells, indicating an immune response to infection. Bacteriophage application, especially at high dosage (FB9), effectively stimulated the shrimp's immune response by preserving hyaline cell levels, making it a promising eco-friendly alternative for AHPND control
A REVIEW OF THE DEVELOPMENT PACIFIC WHITE SHRIMP (Litopenaeus vannamei) FARMING IN INDONESIA
Get PDFPacific white shrimp (Litopenaeus vannamei) cultivation in Indonesia has been carried out since the early 2000s with satisfactory results. This shrimp is able to replace the previously cultivated black tiger (Penaeus monodon), which experienced cultivation failure due to disease attacks. The pond construction used includes an earthen pond, a lining pond, and a concrete pond, which are equipped with paddlewheels as a source of dissolved oxygen. Pacific white shrimp are mostly cultivated using semi-intensive, intensive, and super-intensive systems, depending on technological input and stocking density. Semi-intensive stocking density is around 50 PL/m2, intensive 100 PL/m2, and super-intensive 500 PL/m2, with productivity of 10 tons/ha, 15 tons/ha, and 42 tons/ha, respectively. There are two types of harvests carried out by farmers in Indonesia, namely partial harvests and total harvests. The main aim of partial harvest is to reduce excessive shrimp biomass, as indicated by a decrease in dissolved oxygen content. Problems that often arise during the cultivation process are disease attacks such as white spots and infectious myonecrosis (IMN) caused by viruses, White Feces Syndrome (WFS) and Acute Hepatopancreatic Necrosis Disease (AHPND) caused by Vibrio parahaemolitycus and Enterocytozoon hepatopenaei (EHP). To increase the productivity of whiteleg shrimp cultivation, the advice given is to minimize disease attacks, namely by installing several biosecurity devices, such as bird scaring devices (BSD), crab protection devices (CPD), and water filtration. In addition, the application of a recirculation aquaculture system, biofloc technology, aquamimicry and whiteleg shrimp cultivation at low salinity (inland) can be an alternative cultivation in the future

Title: Relationship Between Sustainable Financing and Stakeholder Engagement in Marine Tourism DevelopmentThis study investigates the role of sustainable financing and stakeholder engagement in enhancing sustainable economic performance and raising awareness of environmental impacts within the marine tourism sector. The research was conducted between January and March 2024 across three prominent marine tourism destinations in Indonesia, namely Raja Ampat, Bali, and the Komodo Islands. Employing a quantitative approach, primary data were collected through structured questionnaires administered to 167 purposively selected respondents, including tourism operators, policymakers, local community members, representatives of non-governmental organisations (NGOs), and academics—each selected based on their involvement in sustainable tourism initiatives. Data were analysed using Structural Equation Modeling (SEM) to assess the relationships among key variables: readiness to support, sustainable financing, economic performance, environmental impact awareness, and policy support. The findings indicate that readiness to support exerts a significant positive influence on sustainable financing, economic performance, and environmental awareness. Moreover, sustainable financing has a stronger effect on raising environmental awareness than on enhancing economic performance. Environmental awareness, in turn, emerged as a critical determinant of support for sustainability-oriented policies. These results highlight that stakeholder engagement, together with well-structured sustainable financing mechanisms, forms a foundational basis for long-term economic development and environmentally responsible policymaking in marine tourism, particularly in biodiversity-rich areas such as the Komodo Islands
Mangrove and Gastropoda Community Structure in The Coastal of Kampung Laut, Cilacap District
Get PDFMangrove forest is a type of forest found in tidal areas which are inundated at high tide and dry at low tide. Gastropods are biota that are closely related to mangrove ecosystems and are found in many environmental conditions. The purpose of this study was to determine the community structure between mangroves and gastropods associated with mangrove forest areas in Kampung Laut Coast, Cilacap Regency. The results obtained for the most mangrove species were Rhizophora apiculata and Brugeria. Mangrove canopy cover value of 75.56% is included in the good category with dense density. There were 6 types of gastropods associated with mangroves, namely Caenogastropoda, Cycloneritida, Ellobiidae, Neritidae, Potamididae, and Muricidae. The relationship between mangrove ecosystems and gastropods in the Kampung Laut coast is very close. This is due to the fact that most of this area is overgrown with mangrove species Rhizopora spp which are very popular with gastropods
