Abstract

Rumput laut Gracilaria sp. merupakan salah satu rumput laut yang memiliki potensi sebagai penghasil agar, yang banyak dimanfaatkan dalam bebagai industri. Penelitian ini bertujuan untuk mengetahui kemampuan rumput laut Gracilaria sp. dalam beradaptasi dan tumbuh secara optimal pada skala laboratorium dengan meniru kondisi lingkungan alaminya. Metode penelitian menggunakan tiga wadah styrofoam berisi air laut yang telah disaring dan diaerasi, diisi dengan substrat pasir dan potongan karang, serta bibit rumput laut sebanyak 200 gram per wadah. Pemeliharaan dilakukan selama 28 hari dengan pemantauan harian terhadap parameter kualitas air seperti suhu, salinitas, pH dan oksigen terlarut (DO), sedangkan nitrat dan fosfat diukur pada awal dan akhir penelitian. Hasil penelitian menunjukkan pertumbuhan negatif pada semua wadah (A1: -82; A2: -61; A3: -100), yang disebabkan oleh stres adaptasi, kualitas air yang buruk dan pencahayaan tidak optimal. Parameter kualitas air seperti suhu sore hari (28,74–29,25°C) melebihi kisaran optimal (20–28°C), sedangkan kadar fosfat (0,526–1,210 mg/L) dan nitrat (10–25 mg/L) jauh melebihi batas optimal (fosfat: 0,051–0,100 mg/L; nitrat: 1–3 mg/L). Meskipun salinitas (32,82–33 ppt) dan pH (8,08–8,29) berada dalam kisaran yang sesuai, tingginya kadar nutrien dan ketidakstabilan suhu menjadi faktor penghambat utama. Keberhasilan budidaya Gracilaria sp. memerlukan pengendalian ketat terhadap parameter lingkungan, terutama suhu, pencahayaan dan kadar nutrien.

Abstract

Seaweed cultivation in Majene Regency, West Sulawesi, has not experienced significant development as in neighboring Polewali Mandar and Mamuju Regency. This can be seen from the absence of active seaweed cultivation activities in Majene Regency. The aim of this research is to assess the physical and chemical aspects of water to determine the suitability of locations for cultivating Eucheuma cottonii seaweed in Majene waters. The method used to measure ecological suitability included parameters such as temperature, salinity, dissolved oxygen (DO), pH, phosphate, nitrate and salinity. Subsequently, the data is scored to determine suitability classes: suitable (S1) with values ranging from 37 to 48, moderately suitable (S2) with values between 36 and 25 and non sultable (S3)/N) with value 25. The results showed that after applying weighting and scoring, locations such as East Banggae, Pamboang 1, Tubo Sendana, and Sendana 2 showed suitable scoring result with scores of 39, 39, 40, and 40. While locations such as Pamboang 2, Pamboang 3, Malunda, and Sendana 1 showed moderately suitable scoring results with scores of 33, 33, 34 and 36. Majene waters have potential areas for seaweed cultivation based on classes S1 (suitable) and S2 (moderately suitable).Keywords:SeaweedMajene WatersLocation SuitabilityWater QualityAquaculture

Abstract

Abstrak Kegiatan pengabdian ini bertujuan untuk meningkatkan kualitas pakan ikan bandeng melalui pemanfaatan limbah lokal seperti ampas tahu dan rumput laut Padina australis di Kelurahan Baurung, Kabupaten Majene. Metode yang digunakan meliputi sosialisasi, demonstrasi pembuatan pakan, serta pre-test dan post-test untuk mengukur peningkatan pemahaman peserta. Hasilnya menunjukkan peningkatan signifikan dalam pengetahuan masyarakat tentang pembuatan pakan alternatif, pengaturan nutrisi, serta manfaat ekonomi dan ekologis dari pemanfaatan limbah lokal. Peserta juga terlibat aktif dalam sesi tanya jawab dan demonstrasi, menunjukkan kesiapan mereka untuk mengadopsi inovasi ini. Kegiatan ini berhasil memberikan solusi ekonomis dan ramah lingkungan bagi pembudidaya ikan bandeng, sekaligus mendukung praktik budidaya yang berkelanjutan. Kata kunci: ampas tahu; budidaya; ikan bandeng; padina australis; pakan. Abstract This community service activity aims to improve the quality of milkfish feed through the utilization of local waste such as tofu dregs and Padina australis seaweed in Baurung Village, Majene Regency. The methods used include socialization, feed production demonstrations, as well as pre-test and post-test to measure the increase in participants' understanding. The results show a significant improvement in community knowledge about alternative feed production, nutrient regulation, and the economic and ecological benefits of utilizing local waste. Participants were also actively involved in Q&A sessions and demonstrations, indicating their readiness to adopt this innovation. This activity successfully provides an economical and environmentally friendly solution for milkfish farmers, while supporting sustainable aquaculture practices. Keywords: aquaculture; feed, milkfish; padina australis; tofu dregs.
