Abstract

Pusat Studi Mangrove merupakan pengembangan tambak sylfofisheries dengan beberapa jenis mangrove diantaranya adalah Avicennia marina, Rhizophora apiculata, Avicennia alba dan Sonneratia alba. Penelitian ini bertujuan untuk melakukan karakterisasi bakteri pada tutupan mangrove yang berbeda. Serasah yang berlebihan dapat mengakibatkan menumpuknya bahan organik dan meningkatkan derajat keasaman perairan pada tambak silvofishery.  Namun keberadaan bakteri heterotroph yang mampu menguraikan bahan organik diperairan memiliki peran penting dalam mempertahankan keseimbangan ekosistem tambak silvofishery terutama pada petakan dengan persentase tutupan mangrove yang tinggi (>50%). Perencanaan tambak silvofishery dengan menggunakan jenis mangrove yang berbeda diduga akan memberikan hasil yang berbeda, karena adanya perbedaan pada jumlah serasah yang jatuh serta kandungan bahan aktif yang bersifat sebagai antibakteri yang dimiliki jenis mangrove yang berbeda pula.Metode yang digunakan adalah eksperimental skala lapangan dengan parameter Kelimpahan bakteri Heterotrof di perairan dan Kualitas Air yang meliputi pH, suhu dan salinitas.Dari hasil penelitian didapatkan bahwa Kelimpahan bakteri heterotroph pada petakan silvofisheries dengan mangrove Avicennia marina lebih tinggi daripada petakan silvofisheries mangrove Rhizophora mucronata dan parameter kualitas air yang mempengaruhi kelimpahan bakteri heterotroph adalah pH, sedangkan suhu serta salinitas tidak memberikan pengaruh terhadap kelimpahan bakteri heterotroph pada petakan silvofisheries.

Abstract

Chemicals as pest and disease control in aquaculture production are suspected to contain potential toxicity to human health as well as harm to the environment, so this study aimed to use mangrove plants as pesticides made of organic material for pest control in shrimp ponds. One of the pests that are very disturbing is trisipan (Telescopium telescopium) from the Mollusca group. This study aimed to identify the active compounds contained in the latex of Excoecaria agallocha, to determine the cytotoxicity activity of the latex of Excoecaria agallocha and to determine the LC50 of the latex of E. agallocha against Trisipan. This research was conducted from September to December 2019 at the Mangrove Center Pulokerto Pasuruan and the Fish Pathology Laboratory of the Marine and Fisheries Polytechnic of Sidoarjo. The method used is experimental 6 treatments with 3 replications.The results that can be concluded from this study are that the active compound content of Excoecaria agallocha latex has not been determined because it is still in the testing process, the cytotoxicity activity of Excoecaria agallocha sap in brackish water media is higher than the cytotoxicity activity in freshwater media and LC50 of resin E. agallocha against Trisipan was shown in Trisipan with brackish water media and a dose of 400 ppm.

Abstract

One of the factors that influence shrimp cultivation is the presence of algae. Precise knowing algae content in the pond is essential for effective management. Most research in the field of algae species carried out by researchers were observing Chlorella Sp. more than the other algae species, with a particular emphasis on substance concentrations. This study proposed non-invasive techniques for quantifying algae abundance, utilizing optical density (OD) and image processing (IP) methods. Three different algae species are frequently found in Indonesia i.e., Chlorella Sp., Thalassiosira Sp., and Skeletonema Sp. are used as sample. Those samples are cultured and prepared in a certain volume with a certain quantity. For experimental and observation purposes, those samples are then diluted into water based on percentage value. The experimental results provided RGB values, which were then used to establish polynomial equations. To verify these equations, two approaches were employed: synthetic image analysis and evaluation using additional data. The mean average error (MAE) was found to be 3.467 for IP method and 3.513 for OD method. It shows that IP method give better result compared to OD method in this study. However, it is very possible that the two methods will complement each other.
EFEKTIVITAS DAUN KETAPANG (Terminalia catappa) DAN BAWANG PUTIH (Allium sativum) SEBAGAI IMUNOSTIMULAN HERBAL PADA BUDIDAYA IKAN NILA (Oreochromis niloticus) Insivitawati, Era; Wahidi, Budi Rianto; Asmarany, Anja; Hakimah, Nisa; Jayanti, Shara; Setyatuti, Tri Ari; Suseno, Dewi Nurmalita; Sugianti, Budi

Abstract

Budidaya ikan nila (Oreochromis niloticus) berpotensi besar, namun rentan terinfeksi bakteri dan memerlukan solusi alternatif pengganti antibiotik sintetis. Daun ketapang (Terminalia catappa) dan bawang putih (Allium sativum) bersifat antimikroba dan imunostimulan, namun efektivitas dan formulasi optimal masih memerlukan penelitian lebih lanjut. Penelitian ini bertujuan mengevaluasi efektivitas kombinasi daun ketapang dan bawang putih untuk mencari alternatif pengendalian bakteri yang lebih aman, mengingat penggunaan obat berlebihan dapat memicu resistensi. Daun ketapang dan bawang putih dipilih sebagai imunostimulan herbal yang potensial menekan bakteri Aeromonas tanpa dampak negatif bagi lingkungan. Metode yang digunakan adalah eksperimen Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu  Perlakuan Kontrol tanpa pemberian ekstrak daun ketapang dan bawang putih, Perlakuan A (komposisi 75 % daun ketapang dan 25% bawang putih), Perlakuan B (komposisi 50 % daun ketapang dan 50% bawang putih), dan Perlakuan C (komposisi 25 % daun ketapang dan 75% bawang putih). Pengujian mencakup uji fitokimia, zona hambat, DPPH (2,2-Diphenyl-1-picrylhydrazyl), analisis kualitas air dan pertumbuhan ikan dengan uji statistik. Hasil menunjukkan kombinasi 50% daun ketapang dan 50% bawang putih (Perlakuan B) merupakan yang terbaik dan berpotensi meningkatkan daya tahan tubuh ikan dengan kadar alkaloid tertinggi sebesar 37,91% (b/b) dengan persentase Relative Percent Difference (RPD) 1,5%, IC50 Uji DPPH 3,79 mg/ml, menghambat pertumbuhan bakteri yang ditunjukkan dengan hasil zona hambat terbesar, pertumbuhan berat terbaik dengan ABW mencapai 17,60 ± 6,84 gram/ekor dan ADG 1,53 g/minggu. Penelitian ini mengindikasikan bahwa kombinasi daun ketapang dan bawang putih dapat menjadi imunostimulan alami yang ramah lingkungan dalam budidaya ikan nila.

Abstract

White snapper (Lates calcarifer) is a high value aquaculture commodity with increasing market demand. This study aimed to analyzed the growth performance of white snapper fry during the nursery phase at the ODE Aquaculture and Agriculture Hatchery Unit, Brunei-Muara District, Brunei Darussalam, from March to June 2023.The nursery utilized controlled fiberglass tanks equipped with aeration and a flow-through water system. Two types of tanks were used: rectangular tanks measuring 4 × 1.5 × 1 m (capacity: 6,000 L) and circular tanks with a diameter of 2 m (capacity: 3,140 L). A total of 100,000 fry were stocked, with 30,000–40,000 fry per tank. Observed parameters included survival rate (SR), absolute length growth rate, absolute weight growth rate, specific growth rate (SGR), and feed conversion ratio (FCR). Water quality parameters measured were temperature, salinity, and pH. Results indicated an absolute length growth rate of 1.2 cm/week, surpassing previous studies reporting only 0.4 cm/week. The absolute weight growth rate was 1.3 g/week, exceeding the 0.6–1 g/week range reported in other research. The FCR was 0.33, demonstrating excellent feed efficiency. However, the survival rate was 30.77%, below the standard for controlled nursery systems (>50%), likely due to high stocking density and cannibalism. Harvest size ranged from 8 to 9 cm. Water quality remained stable, with temperatures between 31–32.5°C, pH levels from 7.6–8.3, and salinity ranging from 30–32 ppt. Despite the low survival rate attributed to high stocking density, the nursery phase at this facility achieved commendable growth rates compared to previous studies. This success is supported by stable water quality and the provision of high-protein feed.
