Abstract

Acute Hepatopancreatic Necrosis Disease (AHPND), caused by Vibrio parahaemolyticus, poses a major threat to the cultivation of Pacific white shrimp (Litopenaeus vannamei) due to its high mortality rate. This study aimed to evaluate the effectiveness of bacteriophage therapy on the non-specific immune response of shrimp, assessed through Differential Hemocyte Count (DHC) analysis. The research was conducted over six months using a Completely Randomized Design with seven treatment groups, including positive control (KP), negative control (KN), antibiotic treatment (KA), and three bacteriophage dosages: 10⁷ PFU/mL (FB7), 10⁸ PFU/mL (FB8), and 10⁹ PFU/mL (FB9), all challenged with V. parahaemolyticus at 10⁵ CFU/mL. DHC observations were carried out on days 0, 1, 3, and 7 post-treatment. The results indicated that the bacteriophage-treated group, particularly FB9 (10⁹ PFU/mL), maintained a hyaline cell proportion of 50–57% through day 7, similar to the immune profile of the negative control. In contrast, the positive control exhibited a marked decrease in hyaline cells and an increase in granular cells, indicating an immune response to infection. Bacteriophage application, especially at high dosage (FB9), effectively stimulated the shrimp's immune response by preserving hyaline cell levels, making it a promising eco-friendly alternative for AHPND control.

Abstract

Given the complexity of the Banda Sea, which has rapidly changing environmental factors, studies are needed to determine the optimal location for important fishing, such as bigeye tuna (BET). To map optimal fishing locations, statistical and machine-learning methods are used through an understanding of the dynamics of chlorophyll-a (Chlo) concentrations and sea surface temperature (SST) and fish catch data as key factors. Using the fishing logbook and oceanographic data from 2014 to 2022, this study applies the methods of generalized Additive Model (GAM) and Empirical Cumulative Distribution Function (ECDF) to analyze the effect of Chlo and SSTs on Catch per Unit Efforts (CPUEs). Due to GAM's suboptimal performance, ECDF is chosen as the primary method. Determining the optimal value range using k-means and the elbow method showed an optimal Chlo range of 0.087–0.30 mg/m³ and SST of 29.46–30.45°C. The analysis showed the best catching conditions from January to March. These findings support sustainable fishing by providing a monthly map of optimal fishing zones, helping fishers adapt to dynamic conditions. Further research is suggested to integrate real-time data and advanced techniques to improve location accuracy.

Abstract

Hadirnya wahana Unmanned Surface Vehicle (USV) membuat survei kualitas air pada wilayah perairan yang luas menjadi lebih mudah dan cepat serta dapat meminimalkan risiko pada pengambilan data di wilayah yang berbahaya. Namun, dikarenakan USV sering mengalami kerusakan terutama pada bagian propulsinya dan sulit dalam melakukan perawatan sensor maka diperlukan instrumen pengukur kualitas air yang dapat dilepas pasang. Penelitian ini bertujuan prototipe instrumen pengukur kualitas air yang dapat dilepas pasang pada USV dan mengukur seberapa efektifnya kinerja sensor pada instrumen tersebut. Pengukuran suhu menggunakan sensor suhu DS18B20, pH Module 4502C, TDS Meter DFRobot, dan GPS Ublox Neo-8M. Sedangkan, sistem komunikasi datanya menggunakan modul Long Range (LoRA) Ebyte E32 433T20D sebagai sistem dengan frekuensi gelombang radio 433 MHz. Hasil pengukuran menunjukkan tingkat akurasi sensor sudah sangat baik bahkan melebihi tingkat akurasi pada spesifikasi teknisnya namun untuk akurasi GPS masih rendah karena pengambilan data dilakukan pada kondisi cuaca berawan, Bagitu juga dengan kekuatan transmisi sinyal hanya optimal pada jarak <1.300 m. Di sisi lain, tingkat presisi sensor masih kurang baik sehingga pengukuran data menjadi tidak stabil dan berubah-ubah. Hasil olahan data kualitas air mampu divisualisasikan secara spasial karena terdapat data koordinat untuk setiap parameter kualitas air yang diukur.
