Abstract

Chlorella sp. is a microalga that can grow and develop in wastewater media, including sago liquid waste that is not utilized and becomes a pollution material. This study aims to determine the utilization of sago liquid waste organic fertilizer on the growth of Chlorella sp. This research was conducted in February 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Riau University. The method used was the experimental method, by applying a complete randomized design (CRD) with four treatments and three replicates. The treatments were as follows: T0 (control), T1 (150 ml sago liquid waste), T2 (200 ml), and T3 (250 ml). The initial density of Chlorella sp. was 250 x103 cells/ml, and cell abundance observations were made for 14 days. The parameters observed were cell abundance, specific growth rate, and water quality (temperature and pH). The results showed that the utilization of sago liquid waste affected the abundance of Chlorella sp. 150 ml concentration and gave the best results on cell abundance of 233.33 x103 cells/ml with the peak population occurring on day 9. Water quality during the study was still in the normal range and can be tolerated for the growth of Chlorella sp, namely temperature ranging from 26-31o C and pH 6.2-8.0

Abstract

Water quality plays an important role in maintaining and increasing fish production. Tilapia (Oreochromis niloticus) is one of Indonesia's freshwater fish that has economic value. To increase production, tilapia cultivation is carried out intensively, characterized by high stocking density and provision of protein-rich feed. Good water quality control and feeding are key to the success of this intensive culture. Biofloc technology is one of the appropriate technologies for intensive tilapia rearing since fish can live at high densities and have a wide environmental tolerance. biofloc technology is an alternative solution to problems in overcoming cultivation waste such as ammonia and nitrite. Based on the above, this study was conducted to determine the effectiveness of the biofloc system in converting ammonia compounds, improving water quality in the aquaculture environment, and understanding the relationship between water quality and tilapia growth. The research was conducted for 60 days to measure several water quality parameters, namely temperature, dissolved oxygen, acidity (pH), and ammonia, and to observe the growth parameters of tilapia. The treatment applied in this study was the addition of probiotics in feed with four treatments and three replications. The results showed that the biofloc system's water quality is tolerant to tilapia growth. The best growth results in treatment A with each value of absolute weight 14.70±0.10d, absolute length 6.70 ± 0.10d, specific growth rate 3.87±0.01c, and survival rate 100±0.00b

Abstract

Aeromonas hydrophila is a gram-negative bacterium that can infect fish and is zoonotic to humans. Efforts to prevent this bacterial infection can be made using herbal plants due to the content of secondary metabolite compounds. This study aims to explore plants that have the potential as antibacterials, especially A. hydrophila bacteria. This research was conducted in February 2024 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The experimental method used included the stages of preparation of plant leaf samples and antibacterial tests using Kirby-Bauer discs. The plants used were the leaves of senduduk (Melastoma malabathricum), kantong semar (Nepenthes sp), lime (Citrus aurantifolia), belimbing bukit (Acetosella barreligeri), sirsak (Annona muricata), mucuna (Mucuna bracteata), Israel grass (Asystasia gangetica), and miana (Coleus scutellariodes). The results showed that the leaves of kantong semar, senduduk, and belimbing bukit could inhibit bacterial growth in a strong category. In contrast, the leaves of sirsak, mucuna, Israel grass, miana, and lime were classified as moderately inhibiting the growth of A. hydrophila bacteria. In conclusion, these herbal plants can potentially prevent A. hydrophila bacterial infection.

Abstract

Kegiatan budidaya perikanan yang semakin meningkat, pakan merupakan salah satu faktor terpenting yang menunjang kelangsungan hidup ikan yang dibudidayakan. Pakan buatan menyerap 60-70% dari biaya produksi, sehingga efisiensi dari pakan tersebut perlu dipertimbangkan agar dapat menghasilkan bobot biomassa ikan yang lebih besar. Oleh karena itu perlu adanya pemberian feed supplement seperti probiotik. Salah satu probiotik yang digunakan dalam pakan adalah probiotik rabal. Probiotik yang dibuat dari Ragi dan Bakteri Asam Laktat (Rabal) merupakan salah satu metode pemanfaatan mikroba dengan cara fermentasi. Kegiatan pembuatan pakan rabal dipraktekkan secara langsung dan diberikan penjelasan kepada mahasiswa dan petani ikan tentang fungsi dari bahan-bahan yang digunakan dalam pembuatan fermentasi probiotik. Pembuatan Pakan Rabal di Desa Muara Langsat bertujuan untuk meningkatkan pengetahuan dan kemampuan warga dalam membuat pakan rabal ramah lingkungan dengan bahan yang mudah didapat, serta memberikan kesadaran kepada warga tentang pentingnya penggunaan probiotik ini menjadi solusi internal untuk menghasilkan pertumbuhan dan efisiensi pakan yang optimal, mengurangi biaya produksi dan pada akhirnya dapat mengurangi beban lingkungan karena akumulasi limbah di perairan.

Abstract

Penetasan telur merupakan tahap penting dalam budidaya ikan yang memengaruhi kelangsungan hidup larva. Metode konvensional dengan bahan kimia seperti formalin dan metilen biru sering menimbulkan dampak negatif terhadap lingkungan dan residu berbahaya bagi kesehatan manusia. Sebagai alternatif, bahan alami seperti daun sirih (Piper betle), daun pepaya (Carica papaya), daun kamboja (Plumeria sp.), daun kersen jamaika, dan belimbing wuluh (Averrhoa bilimbi) telah dilaporkan memiliki sifat antijamur dan antimikroba yang mendukung keberhasilan penetasan. Artikel ini merangkum berbagai penelitian tentang efektivitas bahan alami dalam meningkatkan daya tetas telur ikan. Beberapa studi menunjukkan hasil positif, seperti larutan daun sirih dengan dosis 2 mL/L yang meningkatkan tingkat penetasan hingga 96,67% dan daun pepaya dengan dosis 4 g/0,96 L mencapai 94,06%. Keberhasilan ini terkait dengan kandungan bioaktif seperti fenol, flavonoid, tanin, dan saponin yang bekerja melawan patogen tanpa membahayakan telur. Penggunaan bahan alami mendukung praktik akuakultur yang ramah lingkungan dan berkelanjutan. Namun, diperlukan penelitian lebih lanjut untuk menentukan dosis optimal dan mengurangi potensi efek toksik pada konsentrasi tinggi. Artikel ini memberikan wawasan penting bagi pengembangan teknologi penetasan ikan berbasis bahan alami yang efisien dan aman
