Journal of Aquatropica Asia (JoAA) is an open access scientific periodical managed by the Department of Aquaculture, Bangka Belitung University. JoAA Journal involvement is carried out 2 (two) times a year, namely in July and December in the form of the main manuscript is an article that contains the results of research (research articles). Other manuscript contributions can be in the form of short articles (short communication), articles review, and also special issues. Articles received will be reviewed by reviewers managed by the Editor in Chief before the manuscript is accepted and approved for publication in JoAA. The Journal of Aquatropica Asia (JoAA) accepts articles written in Indonesian or English with regard to aquaculture studies and aquatic ecology in the broadest sense covering aspects of reproduction, nutrition and feed, genetics, physiology, morphology, health of aquatic organisms, water quality, plankton, conservation, and other aspects relevant to the field of aquaculture.

Abstract

High-quality fish feed production is a critical factor in the success of aquaculture systems. The quality of feed pellets, particularly their durability (pellet durability index), directly affects feed efficiency and aquatic environmental quality. This study applied machine learning approaches to predict and optimize pellet durability index in a flat die pelletizing machine used for fish feed production. The dataset consisted of 3,000 observations with 13 operational features collected through IoT sensors. Descriptive statistics were used to summarize overall data characteristics. The target variable was binarized to classify pellets as acceptable or non-acceptable. To address data imbalance, the Synthetic Minority Oversampling Technique (SMOTE) was applied, followed by data cleaning and feature scaling to ensure uniformity. The preprocessed dataset was split into training and testing subsets. Six machine learning models were developed and evaluated using four performance metrics. Logistic Regression and Support Vector Machine achieved the best performance, with accuracy, recall, precision, and F1-score values of 0.756, 1.000, 0.756, and 0.861, respectively. The results indicate that operational factors in the fish feed pelletization process can effectively train predictive models to assess feed quality. The integration of machine learning in fish feed manufacturing offers potential improvements in production efficiency and feed quality for commercial aquaculture applications.

Abstract

The agricultural and plantation industries in Bangka Belitung produce large amounts of organic waste, including mango (Mangifera indica) waste, much of which is not optimally utilized. One alternative utilization is through the production of bioenzymes that can be applied in aquaculture systems. This study aims to analyze the effect of bioenzymes from mango waste on the growth, survival rate, and water quality of tilapia (Oreochromis niloticus) fry. The study was conducted experimentally using four treatments: one control pond without bioenzymes and three experimental ponds with different bioenzyme doses. Parameters observed included length growth, weight gain, survival rate, and water quality during the rearing period. The use of bioenzymes from mango waste has been shown to have a positive impact on tilapia seed cultivation. The administration of bioenzymes, particularly at a dose of 40 ml, was able to optimally enhance the growth of fish fry, as evidenced by increases in weight, length, and specific growth rate. Furthermore, fish survival rates across all treatments remained in the good category, indicating that the use of bioenzymes did not negatively impact the survival of fish fry. Aquarium water quality also remained stable within the optimal range throughout the study, with the 40 ml dose showing the best performance in maintaining parameters such as DO, pH, temperature, EC, and TDS. This water quality stability indicates that bioenzymes play a role in accelerating the decomposition process of organic matter, thus creating a more supportive environment for fish growth. Overall, bioenzymes from mango waste have great potential as an environmentally friendly technology that can increase the productivity of tilapia cultivation by improving growth, survival, and water quality.

Abstract

Udang vaname (Penaeus vannamei) merupakan salah satu komoditas unggulan perikanan budidaya yang memiliki nilai ekonomi tinggi dan permintaan pasar yang terus meningkat setiap tahunnya. Untuk memenuhi kebutuhan tersebut, pelaku usaha menerapkan sistem budidaya superintensif guna meningkatkan produktivitas. Namun, sistem ini memiliki risiko tinggi terhadap penurunan kualitas lingkungan dan meningkatnya kejadian penyakit, terutama yang disebabkan oleh bakteri patogen oportunistik seperti Vibrio sp., yang dapat menyebabkan kematian massal dan menurunkan performa produksi. Salah satu strategi yang banyak dikembangkan untuk mengendalikan permasalahan penyakit tanpa penggunaan antibiotik adalah aplikasi probiotik. Probiotik berperan dalam memperbaiki kualitas air, menekan pertumbuhan bakteri patogen, serta meningkatkan keseimbangan mikrobiota lingkungan budidaya. Penelitian ini bertujuan untuk mengevaluasi efektivitas probiotik dalam menekan keberadaan bakteri Vibrio sp. di media pemeliharaan udang vaname pada sistem budidaya superintensif. Penelitian dilakukan dengan membandingkan dua frekuensi aplikasi probiotik, yaitu satu kali dan dua kali per minggu, dengan dosis 0,5 mL ton⁻¹. Parameter yang diamati meliputi tingkat kelangsungan hidup udang, kondisi klinis, dan dinamika populasi bakteri di media pemeliharaan. Hasil penelitian menunjukkan bahwa aplikasi probiotik satu kali per minggu menghasilkan tingkat kelangsungan hidup yang lebih tinggi, yaitu sebesar 37,38%, dibandingkan dengan aplikasi dua kali per minggu yang hanya mencapai 29,01%. Selain itu, kondisi klinis udang menunjukkan perbaikan setelah pemberian ekstrak herbal melalui pakan, yang diduga berkontribusi terhadap peningkatan daya tahan tubuh udang. Nilai total plate count (TPC) bakteri pada kolam perlakuan tercatat melebihi 10³, yang mengindikasikan adanya peningkatan kualitas air dan stabilitas mikrobiologis akibat perlakuan probiotik. Hasil penelitian ini menunjukkan bahwa pengaturan frekuensi aplikasi probiotik yang tepat berpotensi meningkatkan keberhasilan budidaya udang vaname secara berkelanjutan.
