Abstract

Penelitian ini bertujuan untuk menganalisis kinerja pertumbuhan ikan nila salin yang dibudidaya dengan sistem bioflok. Karena sistem bioflok dinilai dapat menghemat penggunaan pakan, meningkatkan produktivitas budidaya, menghemat penggunaan air, dan dapat dilakukan dengan menggunakan kolam terpal atau kolam bulat. Ikan nila salin yang digunakan memiliki bobot rata-rata 10,6±0,48 gram. Penelitian ini dilakukan selama 90 hari. Penelitian ini dilakukan dengan 2 perlakuan, yaitu perlakuan A (pemeliharaan nila salin dengan sistem bioflok) dan perlakuan B (pemeliharaan nila salin tanpa sistem bioflok). Masing masing perlakuan memiliki 7 ulangan. Data yang diperoleh selama penelitian selanjutnya diuji statistika mengunakan SPSS versi 16.1 sedangkan uji T-Test digunakan untuk mengetahui apakah terdapat pengaruh antara perlakuan yang diberikan. Berdasarkan uji statisika diketahui bahwa laju pertumbuhan bobot rata-rata ikan antara perlakuan A dan B adalah tidak berbeda nyata. Sedangkan untuk rasio konversi pakan dan tingkat kelangsungan hidup memiliki hasil yang bebeda nyata, dimana perlakuan A lebih baik dari pada perlakuan B dengan nilai rasio konversi pakan perlakuan A sebesar 1,06 dan tingkat kelangsungan hidup 98%. Berdasarkan hasil penelitian ini maka budidaya nila salin sebaiknya dilakukan dengan sistem bioflok agar dapat menghemat pengunaan pakan dan tingkat kelangsungan hidup yang lebih baik.This study aims to analyze the growth performance of saline tilapia fish cultivated with the biofloc system. Because the biofloc system is considered to be able to save feed usage, increase cultivation productivity, save water usage, and can be done using tarpaulin ponds/circular ponds. The saline tilapia fish used had an average weight of 10.6 ± 0.48 grams. This study was conducted for 90 days. This study was conducted with 2 treatments, namely treatment A (maintenance of saline tilapia fish with a biofloc system) and treatment B (maintenance of saline tilapia fish without a biofloc system). Each treatment has 7 replications. The data obtained during the study were then tested statistically using SPSS version 16.1, while the T-Test was used to determine whether there was an effect between the treatments. This indicates that the growth performance of saline tilapia fish in treatment A and treatment B was not significantly different. Meanwhile, for the feed conversion ratio and survival rate, the results were significantly different, where treatment A was better than treatment B with a feed conversion ratio value of treatment A of 1.06 and a survival rate of 98%. Based on the results of this study, saline tilapia cultivation should be carried out with a biofloc system to save feed usage and achieve a better survival rate.

Abstract

Water quality can be seen from the diversity of plankton in the waters. Plakton can also be considered as a bioindicator to determine whether the waters are polluted or not. This research was conducted by taking water samples in the waters of the Krueng Pase River and analyzing them in the laboratory. The results of the analysis show that the most common phytoplankton found the type Naviculla sp reached 10%. This type of phytoplankton belongs to the Bacillariophyceae class. Phytoplankton from this group can be a bioindicator of environmental pollution in water.Keywords: Bioindicator; Fitoplankton; Pollutan

Abstract

The whiteleg shrimp (Litopenaeus vannamei) is a prominent species in global aquaculture due to its resilience to environmental fluctuations and high growth potential. The success of the larval phase is critically determined by feed quality and the stability of the culture environment. This study comparatively evaluated the efficacy of various feed types on the performance of Litopenaeus vannamei postlarvae. A comparison was made between live, frozen, and preserved natural feed (Artemia sp.) and formulated pellet feed in terms of growth, survival rate, and Vibrio bacteria abundance. The results highlighted that frozen Artemia sp. (P2) was significantly superior to other treatments. Postlarvae fed frozen Artemia sp. exhibited the highest growth (length and absolute weight) and survival rate, reaching 78.67%, significantly surpassing the pellet-fed group (K1) with a survival rate of only 60.67%. Furthermore, the Vibrio bacteria abundance in the frozen Artemia sp. fed group was also relatively low compared to the pellet-fed group (13.33 CFU mL⁻¹). Although live and preserved Artemia sp. yielded better results than pellet feed, frozen Artemia sp. remains the most effective feed choice for optimizing early-stage L. vannamei aquaculture.

Abstract

This study examines the relationship between zoobenthos diversity, sediment characteristics, and mangrove density in three fishery harbors in Bireuen District: PPI Peudada, PPI Jeumpa, and PPI Jangka. Data were collected using quadrat and line transects with purposive sampling. Peudada showed the highest zoobenthos diversity (H'=0.71) with low dominance (D=0.27) and medium sand substrate. Jeumpa and Jangka were dominated by tolerant species and coarse sand. True mangrove regeneration was more developed in Jeumpa and Jangka, while Peudada was dominated by non-mangrove vegetation. There is a strong relationship between sediment type, zoobenthos diversity, and mangrove structure. Fine sediments favored benthic diversity, while coarse sediments supported mangrove growth. The findings highlight the importance of integrated coastal ecosystem management to sustain ecological functions in fishery ports. Keywords: Bireuen; Coastal Ecosystem; Mangrove; Sediment; Zoobenthos

Abstract

This study was conducted as an initial step in the domestication process of endemic fish in Jambi Province through an artificial feed adaptation approach. In addition, there is little data and research in Jambi Province that systematically discusses and tests artificial feed adaptation as part of domestication. This study aims to analyze the feed adaptation response in the cultivation of sepat fish (Trichopodus pectoralis), tambakan fish (Helostoma temminckii), and betok fish (Anabas testudineus) originating from the public waters of Kota Karang Village, Kumpeh Ulu District, Muaro Jambi as the initial stage of domestication. This study used a completely randomized design) with three treatments and three replicates. The treatments applied were different types of endemic Jambi fish, including sepat fish (T. pectoralis, treatment A), tambakan fish (H. temminckii, treatment B), and betok fish (A. testudineus, treatment C). The fish used in this study were wild fish obtained from public waters in Kota Karang Village, Kumpeh Ulu District, Muaro Jambi Regency. The average initial weight and length of sepat fish were 3.37±0.98 g and 6.32±1.52 cm, tambakan fish 7.65±0.74 g and 8.17±0.59 cm, and betok fish 8.03±1.13 g and 7.57±1.14 cm. Maintenance was carried out for 4 weeks, during which the test fish were fed artificial feed or commercial feed (39% protein). The feeding method was Ad-restricted. Feeding frequency is three times a day, namely in the morning, afternoon, and evening. The results of the study show that the SR value produced is 100% for all treatments. The highest PBM value is found in treatment A (sepat fish) at 1.34 g and the lowest PBM value is found in treatment C (betok fish) at 0.82 g. The highest PPM value was found in treatment A (sepat fish) at 1.12 cm, and the lowest PPM value was found in treatment B (tambakan fish) at 0.39 cm. The highest LPS value was found in treatment C (betok fish) at 6.40%/day, and the lowest LPS value was found in treatment A (sepat fish) at 3.54%/day. In general, the water quality parameters of the maintenance medium were suitable for the growth and survival of freshwater fish.
