Abstract

ABSTRACTThe production value of silver pompano has been increasing annually, with strong market demand both locally and internationally. One significant issue in silver pompano aquaculture is infectious diseases caused by parasites. Water quality, being a critical component of the fish's environment, plays a crucial role in disease occurrence, necessitating effective management practices. This study was conducted at the Center for Mariculture Fisheries (BBPBL) Lampung from July 11 to August 31, 2022, aiming to identify the species, intensity, and methods for examining ectoparasites on silver pompano in floating net cages and to assess water quality management practices that can mitigate the proliferation of parasitic diseases. The methodology employed included direct examination and observation. Ectoparasite assessments at BBPBL Lampung involved scraping the surface of the fish body and mounting the fish gills. The identified ectoparasites in the floating net cages of silver pompano were Pyragraphorus hollisae, Benedenia seriolae, and Neobenedenia girellae. Water quality management in the floating net cages is routinely monitored on a weekly basis.Keywords: BBPBL Lampung, Ectoparasites, Silver Pompano, and Water Quality.

Abstract

ABSTRAKPelabuhan Perikanan Samudera (PPS) Belawan merupakan salah satu pelabuhan terbesar di Sumatera Utara. Alat tangkat yang paling dominan di PPS Belawan adalah Pukat cincin (Purse seine). Alat tangkap Pukat cincin adalah alat tangkap yang aktif karena dalam pengoperasian kapal, metode yang dilakukan yaitu pelingkaran jaring pada gerombolan ikan. Pukat cincin (Purse seine) di PPS Belawan memiliki berbagai ukuran dan kapasitas tangkap yang berbeda-beda. Penelitian ini bertujuan untuk mengetahui dan memberikan informasi tentang tingkat produktivitas hasil tangkap terhadap perbedaan ukuran GT kapal Purse seine yang berbeda di Pelabuhan Perikanan Samudera (PPS) Belawan Sumatera Utara terhadap ukuran kapal 60 GT dan ≥60 GT. Metode yang digunakan pada penelitian ini adalah metode survei. Data yang diperoleh selanjutnya dianalisis dengan analisis produktivitas dan analisis regresi linear berganda. Berdasarkan hasil penelitian yang dilakukan bahwa produktivitas kapal berukuran ≥60 GT GT lebih besar dibandingkan dengan produktivitas kapal 60GT. Hal ini disebabkan karena semakin besar ukuran kapal maka jumlah tangkapan semakin banyak sehingga semakin tinggi tingkat produktivitasnya.Kata Kunci: Gross Tonnage, Produktivitas, Pukat Cincin (Purse Seine) ABSTRACKBelawan Ocean Fishing Port (PPS) is one of the largest ports in North Sumatra. The most dominant fishing gear in PPS Belawan is purse seine. Purse seine fishing gear is an active fishing gear because in the operation of the ship, the method used is the looping of the net in schools of fish. Purse seines in PPS Belawan have various sizes and different fishing capacities. This study aims to determine and provide information about the level of productivity of the catch against the different GT sizes of different Purse seine vessels at the Port of Ocean Fisheries (PPS) Belawan North Sumatra against the size of the ship 60 GT and ≥60 GT. The method used in this research is the survey method. The data obtained were then analysed with productivity analysis and multiple linear regression analysis. Based on the results of the research conducted that the productivity of ships ≥60 GT GT size is greater than the productivity of ships 60 GT. This is because the larger the size of the ship, the more the number of catches so that the higher the productivity level.Keywords: Gross Tonnage, Productivity, Purse Seine

Abstract

ABSTRAKPesisir pantai barat-selatan Aceh, khususnya Kabupaten Aceh Barat di Pangkalan Pendaratan Ikan (PPI) Ujong Baroh memiliki keanekaragam hayati yang luar biasa, terutama untuk spesies ikan pari sebagai salah satu kelompok ikan bertulang rawan dan memiliki peran dalam menjaga keseimbangan ekosistem. Keberadaan spesies tersebut mengalami penurunan akibat penangkapan berlebih, rendahnya kesadaran terkait konservasi, serta lemahnya implementasi kebijakan terhadap perlindungan ikan pari. Penelitian ini bertujuan untuk menganalisis sebaran spesies pari yang ditangkap para nelayan beserta jumlahnya, analisis kondisi yang memungkinkan dilakukan untuk konservasi, dan analisis kebijakan yang layak dilakukan untuk memastikan keberlangsungan hidup ikan pari. Penelitian dilakukan melalui survei langsung di PPI Ujong baroh untuk melakukan observasi, wawancara dan lain-lain. Analisis data dilakukan dengan pemaparan informasi mendasar terkait jumlah dan sebaran spesis pari yang ditangkap oleh masyarakat, analisis Strengths, Weakness, Opportunities, dan Threats (SWOT) untuk mengidentifikasi strategi konservasi yang tepat, serta kondisi yang mungkin untuk diambil sebagai tindaklanjutnya. Hasil observasi menunjukkan terdapat 11 jenis ikan pari yang sering ditangkap oleh nelayan di PPI Ujong Baroh, meliputi dua jenis ordo berbeda yaitu Myliobatiformes dan Rhinopristiformes. Hampir seluruh jenis pari tersebut berada dalam status Terancam Punah, bahkan spesies pari barong (Rhina ancylostoma) berada dalam status yang lebih mengkhawatirkan. Hasil analisis SWOT menunjukkan posisi strategi pengelolaan ikan pari saat ini berada dalam Kuadran III (strategi defensif), dimana posisi kelemahan dan ancaman lebih dominan dibandingkan kekuatan dan peluang. Kelemahan internal tersebut berasal dari berbagai aspek nelayan, penjual dan pemerintah. Selain itu, ancaman terhadap keberlangsungan hidup pari juga cukup besar karena permintaan pasar yang tinggi serta maraknya praktik penangkapan ilegal/destruktif. Meskipun hasil analisis SWOT menunjukkan posisi yang lemah dan memerlukan strategi bertahan, kekuatan dan peluang yang tersedia tetap memiliki peran penting jika dimanfaatkan secara strategis, sehingga arah kebijakan berfokus pada penguatan faktor pendukung, serta memperbaiki kelemahan dan mengantisipasi ancaman. Beberapa faktor kekuatan yang dapat dioptimalkan berupa keberadaan fasilitas PPI Ujong Baroh, pengalaman nelayan lokal dalam praktik penangkapan, dan dukungan dari pemerintah daerah dalam bentuk kebijakan kelembagaan. Kata Kunci: strategi, pengelolaan, berkelanjutan, kepunahan , SWOT.ABSTRACTThe southwestern coastal region of Aceh, particularly in West Aceh Regency at the Ujong Baroh Fish Landing Base (PPI), is home to remarkable biodiversity, especially among ray species, which are cartilaginous fish playing a vital role in maintaining ecosystem balance. However, the presence of these species  has  been  declining  due  to overfishing,  low awareness  of conservation  efforts,  and  weak enforcement of protective regulations. This study aims to analyze the distribution and quantity of ray species caught by local fishermen, assess feasible conservation measures, and evaluate policy options to ensure the sustainability of ray populations. Field research was conducted at PPI Ujong Baroh through direct surveys, observations, interviews, and other qualitative methods. Data analysis involved a presentation of basic information on species diversity and catch distribution, a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis to identify appropriate conservation strategies, and a review of potential follow-up actions. Observations revealed 11 ray species commonly caught by local fishermen, encompassing two distinct orders: Myliobatiformes and Rhinopristiformes. Nearly all of these species are classified as Threatened, with the wedgefish (Rhina ancylostoma) listed in a more critical conservation status. The SWOT analysis indicates that current ray management strategies fall into Quadrant III (defensive strategy), where weaknesses and threats outweigh strengths and opportunities. These internal weaknesses stem from factors involving fishers, traders, and governmental institutions. Moreover, the sustainability of ray populations is under significant threat due to high market demand and the prevalence of illegal or destructive fishing practices. Despite these challenges, the identified strengths and opportunities can still play a strategic role if leveraged effectively. Therefore, policy direction should focus on reinforcing supportive factors while addressing weaknesses and mitigating threats. Key strengths include the existing infrastructure at PPI Ujong Baroh, the experience of local fishermen, and support from local governments in the form of institutional policies.Keywords: strategy, management, sustainability, extinction, SWOT

The device is equipped with an ESP8266 module as the main microcontroller, which connects to the IoT system via Wi-Fi. A 10 Wp solar panel and a 12 V 6 Ah battery are used to ensure the device operates autonomously, allowing it to function continuously without relying on conventional power sources. Data collect-ed from the device, such as tidal height, is transmitted in real-time to a custom-developed web-site. The website is integrated with a MySQL database to store the measured tidal data, facilitat-ing easy access to historical data and further analysis. The results of this study demonstrate that the solar-powered tidal monitoring device based on IoT operates effectively, offering an efficient and environmentally friendly solution for tidal monitoring.Keywords: ESP8266, Internet of Things (IoT), Solar Panel, Tidal Monitoring, Website.
