Abstract

Coral reefs are massive deposits of calcium carbonate (CaCO3) produced by coral animals.  Coral reefs in the water are easily damaged due to natural events and destrutive human activities in the water and the influence of upland.   The purpose of this paper is to provide information related to the recovery of coral reef ecosystems through coral recruitment and coral transplantation and the role of the community.  The method used is the quantitative method.  Recruitment and transplantation use media as a place to attach or bind coral fragments.  Coral recruitment is done by relying on the reproduction of the coral itself, while transplantation is done by taking coral fragments from the broodstock. The placement of coral recruitment and transplantation media needs to pay attention to water depth, brightness, substrate, sedimentation, and water current patterns.  In addition, the government, community, and related parties are needed to handle damage and maintain and manage coral reef ecosystems for sustainability. Keywords: Coral Recruitment; Coral  Transplantation; Coral Reef Abstrak Terumbu karang merupakan  endapan massif kalsium karbonat (CaCO3) yang dihasilkan oleh hewan karang .  Terumbu karang di perairan mudah mengalami kerusakan akibat kejadian alam maupun kegiatan manusia yang bersifat destrutif di perairan maupun pengaruh dari lahan bagian atas (upland).   Tujuan penulisan ini yaitu untuk memberikan informasi terkait dengan pemulihan ekosistem terumbu karang  melalui rekrutmen karang dan transplantasi karang serta peran masyarakat.  Metode yang digunakan yaitu metode kuantitatif.  Rekrutmen dan transplantasi menggunakan media sebagai tempat penempelan maupun mengikat fragmen karang.  Rekrutmen karang dilakukan dengan mengandalkan reproduksi dari karang itu sendiri, sedangkan transplantasi dilakukan dengan mengambil fragmen karang dari indukan. Lokasi penempatan media rekrutmen dan transplantasi karang perlu memperhatikan kedalaman perairan, kecerahan, substrat, sedimentasi dan pola arus perairan.  Selain itu, peran pemerintah, masyarakat dan pihak terkait diperlukan untuk penanganan kerusakan, menjaga dan pengelolaan ekosistem terumbu karang untuk keberlanjutan.

Abstract

Sulawesi waters are directly affected by the dynamics that occur in the Pacific Ocean. The ENSO phenomenon that occurs in the Pacific Ocean can also be felt in the waters of the Sulawesi Sea. The dynamics of oceanographic parameters can cause climate change. The extreme impact of climate change is mainly the occurrence of rising temperatures and seasonal shifts. The purpose of this study is to analyze the variability of spatial and temporal anomalous distribution of sea surface temperature and chlorophyll-a. This study used monthly AQUA Modis image data, conducted by analyzing the spatial and temporal distribution of sea surface temperatures during the two decades of the period 2003 - 2022. This analysis is based on abnormal values obtained from subtracting parameter values from historical values (the average value of all data). The results of spatial variability analysis of sea surface temperature and chlorophyll –show anomalous variations occur in the western and transitional season periods I, while in the eastern season and transition II positive anomalous values dominate the eastern waters negative anomalies dominate the western waters opposite to chlorophyll – a. This study showed that there was an increase in sea surface temperature slope by 0.000840C / year while in chlorophyll - a there was a decrease in slope by 0.00072mg / m3 / year. Keywords: Spatial, Temporal, SPL, Chlorophyll – a, Climate Change. Abstrak Perairan Sulawesi mendapatkan pengaruh secara langsung dari dinamika yang terjadi di Samudera Pasifik.

Abstract

Proper handling of fish or fishery products from ships to consumers necessitates collaboration among fishermen, government agencies, and other stakeholders. By adopting a holistic approach encompassing technical, regulatory, and educational aspects, we can ensure the efficient and sustainable operation of fisheries supply chains for all involved parties. This article presented a literature review on good fish handling practices from ship to consumer, focusing on onboard handling, auctions, landing, and transportation. Using the search term 'Good Handling Practices for Fishing Products,' six articles out of 4,470 were identified that met the criteria for further discussion. The literature review findings highlighted optimal strategies for increasing fishing, auction, and transportation processes. These included improving record-keeping and documentation, implementing aerator systems to preserve fish quality, bulk fish cooling using ice cubes without water to mitigate quality deterioration, ensuring sanitation of fish distribution support equipment to prevent bacterial contamination, and utilizing tools such as Trolley Lifters to increase the efficiency of the fish distribution process. Therefore, governmental and non-governmental institutions should provide support and training to fishermen to maximize both the quality and quantity of fish catches.

Abstract

Nile tilapia (Oreochromis niloticus) is also known as tilapia. Tilapia shows an adequate ability to grow and survive even in poor habitats. The success of tilapia farming activities is influenced by several factors, one of which is feed. This study aims to see the effect of feeding different types of feed: marine fish feed (Otohime S2) and freshwater fish feed (MS Preo 320) on tilapia growth. Tilapia fry was kept in an aquarium for each treatment and fed three times a day for 30 days. Data were analyzed using a completely randomized design to determine the effect of feed on tilapia growth (Wm, Lm, SGR, FCR, and SR). Based on ANOVA (α = 0.05), it detected marine fish feed slightly increased tilapia growth but not significantly, except for Lm. It is caused by tilapia being at seed age length growth is more dominant than body weight. The factor causes a slight increase in tilapia growth given marine fish feed has a higher protein content than freshwater fish feed. Water quality components consisting of temperature, DO, and pH (26 – 30,5oC; 4,88 – 5,8 mg/l; 8,25 – 8,32) are in the range of values by the water quality standards for tilapia fry. Keywords: feed, growth, tilapia Abstrak Ikan nila (Oreochromis niloticus) juga dikenal dengan nama tilapia. Tilapia memiliki kemampuan berkembang dan bertahan hidup yang baik bahkan pada habitat yang buruk. Keberhasilan kegiatan budidaya tilapia dipengaruhi beberapa faktor, salah satunya adalah pakan. Penelitian ini bertujuan untuk melihat pengaruh pemberian jenis pakan yang berbeda, yaitu pakan ikan air laut (Otohime S2) dan pakan ikan air tawar (MS Preo 320) terhadap pertumbuhan benih nila. Benih nila dipelihara dalam akuarium untuk tiap perlakuan dan diberikan pakan sebanyak tiga kali sehari selama 30 hari. Analisis data dilakukan dengan Rancangan Acak Lengkap untuk melihat adanya pengaruh pakan terhadap pertumbuhan nila (Wm, Lm, SGR, FCR, dan SR). Berdasarkan hasil ANOVA (α = 0,05) diperoleh informasi bahwa pakan ikan air laut sedikit memberikan peningkatan pertumbuhan nila tetapi tidak signifikan, kecuali Lm. Hal ini dikarenakan nila pada usia benih memiliki pertumbuhan panjang lebih dominan dari bobot tubuhnya. Faktor yang menyebabkan terjadinya peningkatan nilai pertumbuhan nila yang diberikan pakan ikan air laut adalah kandungan protein yang lebih tinggi dari pakan ikan air tawar. Komponen kualitas air yang terdiri dari suhu, DO, dan pH (26 - 30,5oC; 4,88 - 5,8 mg/l; 8,25- 8,32) berada pada kisaran nilai yang sesuai dengan baku mutu kualitas air bagi benih nila. Kata kunci: nila; pakan; pertumbuhan.

Abstract

Water pollution happening in the sea results in changes to the composition or structure of the water affected by human activities and natural processes. This leads to water having qualities and functions that do not align with their intended uses and can disrupt human life, marine biota, and marine ecosystems. Pollution in the marine ecosystem undoubtedly affects marine products in various aspects of life. This article used a literature review method to gather the necessary data for explaining the discussed topic. This article aims to explain the harmful impacts of marine pollution on consumer health, economic value, and the aesthetic value of the marine ecosystem. Based on the results of literature studies conducted through secondary data analysis from published journals in the last 10 years (2015-2024), it was found that marine pollution contaminated with bacteria or pathogens due to chemical substances can disrupt human health, causing symptoms such as vomiting, diarrhea, stomach pain, collapse, and even death. The economic aspect also experienced its impacts, such as the decrease in fishermen's catch and the disruption of the beauty of the marine ecosystem due to changes in water composition, leading to the sea appearing cloudy and odorous, and being filled with waste. Keywords: Dangers of Marine Pollution, Consumer Health, Economy, Aesthetics

Abstract

Fish is a food that easily deteriorates in quality. After the fish is caught or dies, the decomposition process begins to occur, this process lasts 12-20 hours at tropical temperature conditions, depending on the species, fishing method, and fishing equipment. The cause of the decline in fish quality is the activity of bacteria and enzymes by breaking down the components of the fish's body tissue, resulting in physical changes, namely softening of the meat and chemical changes that produce a foul smell due to volatile compounds. This research aims to determine the effect of chitosan solution on the durability of fresh skipjack tuna during storage based on the Total Volatile Base (TVB) value. The results of the research showed that the average TVB content of fresh skipjack tuna from treatment (AB) ranged from 8.48 - 16.78 mg N/100 g, still in the fresh category. BNT follow-up tests showed that the treatment of chitosan concentration and storage time significantly affected the skipjack tuna’s TVB value. Keywords: Demersal fish, organoleptic, pH, Tobelo Abstrak Ikan merupakan bahan pangan yang mudah mengalami kemunduran mutu. setelah ikan ditangkap atau mati, proses pembusukan mulai terjadi, proses ini berlangsung 12-20 jam pada kondisi suhu tropic, tergantung spesies, cara tangkap dan alat penangkapan. penyebab kemunduran mutu ikan adalah aktivitas bakteri dan enzim dengan cara mengurai komponen jaringan tubuh ikan sehingga terjadi perubahan pada fisik  yakni melunaknya daging san perubahan kimia yang menghasilkan bau busuk akibat senyawa-senyawa yang mudah menguap. Penelitian ini bertujuan untuk mengetahui pengaruh larutan kitosan terhadap daya awet ikan cakalang segar selama penyimpanan berdasarkan nilai Total Volatile Base (TVB). Hasil penelitian menunjukkan bahwa rata – rata kandungan TVB ikan cakalang segar dari perlakuan (AB) berkisar antara 8,48 – 16,78 mg N/100 g masih dalam kategori segar Uji lanjut BNT menunjukkan perlakukan konsentrasi kitosan dan lama penyimpanan berpengaruh nyata pada nilai TVB ikan cakalang segar.
