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

Abstract

ABSTRAKIkan capungan banggai asalnya hanya ditemukan di perairan sekitar Kepulauan banggai Sulawesi Tengah, namun saat ini telah menyebar ke berbagai wilayah termasuk perairan Kota Baubau Sulawesi Tenggara. Penelitian ini bertujuan mengkaji distribusi ukuran, pola pertumbuhan dan faktor kondisinya di perairan pesisir Kota Baubau yang merupakan habitat baru. Sampel ikan dikumpulkan dengan metode jelajah sepanjang perairan dimana ikan tersebut tersebar, diukur panjang totalnya, dan ditimbang beratnya. Panjang total ikan yang didapatkan berkisar antara 38,40-83,50 mm dan berat berkisar antara 0,64-8,17 gram. Kelas ukuran ikan yang didapatkan cukup bervariasi dan berada dalam fase juvenil hingga dewasa. Analisis hubungan panjang dan berat ikan secara keseluruhan menunjukkan pola pertumbuhan yang bersifat alometrik positif (b = 3,0058), namun terdapat perbedaan antara ikan ukuran juvenil dan dewasa dimana ikan juvenil memiliki pola pertumbuhan yang bersifat alometrik negatif (b = 2,7275). Analisis faktor kondisi juga menunjukkan perbedaan, dimana ikan dewasa memiliki nilai faktor kondisi yang lebih rendah dibanding juvenil. Namun, secara keseluruhan ikan memiliki pertumbuhan dan faktor kondisi yang cukup baik, sehingga dapat berkembang di habitat baru ini. Dalam aspek pengelolaan, perlu dilakukan kontrol populasi dan pemantauan lebih lanjut terhadap dampak ekologis, karena mungkin saja spesies ini dapat menjadi invasif jika populasinya meningkat pesat dan mengganggu ekosistem lokal.Kata Kunci: Capungan banggai, dewasa, faktor kondisi, juvenil, pola pertumbuhanABSTRACTThe banggai cardinalfish is originally only found in the waters around the Banggai Islands, Central Sulawesi., but now it has spread to various regions including Baubau City waters, Southeast Sulawesi. This study was aimed to examine size distribution, growth patterns, and condition factors of the fish in the coastal waters of Baubau City which is a new habitat. Fish samples were collected using the exploration method along the waters where the fish are spread, their total length was measured, and their weight was weighed. The total length of the fish obtained ranged from 38.40-83.50 mm and their weight ranged from 0.64-8.17 grams. The size classes of the fish obtained were quite varied and were in the juvenile to adult phase. Analysis of length-weight relationship of the fish as a whole showed a positive allometric growth pattern (b=3.0058), but there was a difference between juvenile and adult fish where juvenile had a negative allometric (b = 2.7275). Condition factor analysis also showed differences, where adult had lower condition factor values than juveniles. However, overall the fish have quite good growth and condition factors, so they can thrive in this new habitat. In terms of management, population control and further monitoring of ecological impacts are needed, because this species can become invasive if its population increases rapidly and disrupts the local ecosystem.Keywords: Banggai cardinalfish, adults, condition factors, juveniles, growth patterns

Types of treatment A (control 0 ml EM4 probiotic + 9.54 grams of pellet feed), B (EM4 probiotic doses 11 ml + 11.16 grams of pellet feed), C (EM4 probiotic doses 13 ml + 10.74 grams of pellet feed), D (EM4 probiotic doses 15 ml + 10.20 gram of pellet feed). The parameters measured were relative growth rate, feed conversion ratio, feed utilization efficiency and survival rate. The results showed that the addition of EM4 probiotic doses into pellet feed had a significant effect on the average relative growth rate of 7.06 ± 0.5%/week, the average feed conversion ratio of 0.9 ± 0.2, the average feed utilization efficiency of 80.63 ± 10.3% and had no significant effect on the average survival rate of 66.67 ± 13.8%. The conclusion obtained was that the best treatment in treatment B with the addition of EM4 probiotic doses of 11 ml/gram.Keywords: EM4 probiotic dosage, Fish pelet feed, tilapia growth, tilapia fish

Abstract

ABSTRAKPenelitian untuk mengetahui pengaruh ekstrak biji Salvia hispanica. L terhadap kesehatan ikan patin yang diinfeksi bakteri Edwardsiella. tarda. Biji Salvia hispanica.L diekstraksi dengan pelarut etanol 70%, dan memiliki nilai rendemen sebesar 1,6%. Kultur bakteri Edwardsiella. tarda pada media TSA. Ikan patin diinfeksi bakteri Edwardsiella. tarda 107cfu/ikan. Nilai (IC50) ekstrak Salvia hispanica.L adalah 11,1 mg/L. Pengamatan kesehatan ikan dilakukan secara makroskopis dan mikroskopis. Parameter makroskopis adalah Average Body Weight, Average Daily Growth and Survival Rate, sedangakan mikroskopis adalah pengamatan histopat organ ginjal dan hepar Organ ginjal ikan yang diinfeksi bakteri Edwardsiella. tarda namun tanpa diberi ekstrak tampak degenerasi vakuola dan nekrosis pada sel tubulus ginjal, sedangkan organ ginjal ikan kontrol dan ikan yang diberikan ekstrak dengan dosis ¼ IC50, ½ IC50, IC50 dan 2IC50 tampak sehat dan normal. Pada organ hepar ikan yang diinfeksi bakteri Edwardsiella. tarda namun tanpa ekstrak tampak ada nekrosis pada sel hepatosit, melanomakrofag serta degenerasi vakuola, sedangkan organ ginjal ikan kontrol (A) dan ikan yang diberikan ekstrak tampak sehat dan normal. Nilai ABW, ADG dan SR tertinggi adalah ikan yang diberikan dosis ekstrak Salvia hispanica.L dengan dosis IC50 sebelum diinfeksi Edwardsiella. tarda (D) dengan nilai ABW (86,5 gram), ADG (0,36 gram/day) dan SR (100%).Kata Kunci: Salvia hispanica.L, Edwardsiella tarda, Pangasianodon hypophthalmusABSTRACTResearch to determine the effect of Salvia hispanica. L seed extract on catfish’health which infected with Edwardsiella. tarda. Salvia hispanica. L seeds were extracted with 70% ethanol, and had a yield value of 1.6%. Edwardsiella. tarda had been cultured on TSA, Catfish infected with Edwardsiella. tarda 107cfu/fish. The (IC50) of Salvia hispanica. L extract was 11.1 mg/L. Fish health observations were carried out macroscopically and microscopically. Macroscopically were Average Body Weight, Average Daily Growth and Survival Rate, while microscopically were studying histopath of kidney and liver. The kidney’s fish infected with Edwardsiella. tarda without being given extract showed vacuole degeneration and necrosis in the renal tubule cells, while the kidney’s control fish and fish given extract at doses of ¼ IC50, ½ IC50, IC50 and 2IC50 looked healthy and normal. The liver’s fish infected with Edwardsiella. tarda without extract, there was necrosis in hepatocyte cells, melanomacrophages and vacuole degeneration, while the kidney’s control fish (A) and fish given extract looked healthy and normal. The highest ABW, ADG and SR were found in fish that given a dose of Salvia hispanica.L extract with an IC50 dose before infecting Edwardsiella. tarda (D) with ABW (86.5 grams), ADG (0.36 grams/day) and SR (100%).Keywords: Salvia hispanica.L, Edwardsiella tarda, Pangasianodon hypophthalmus
