Abstract

Ikan jurung merupakan salah satu ikan endemik air tawar di sungai Tapanuli Tengah yang sering disebut dengan ikan batak (Neolossochilus thienemanni). Pemuasaan secara periodik dapat meningkatkan kecepatan pertumbuhan ikan yang setara bahkan lebih tinggi jika dibandingkan dengan ikan yang tidak dipuasakan. Penelitian ini bertujuan untuk mengetahui pengulangan siklus pemberian pakan yang diikuti dengan pemberian pakan tetap terhadap konsumsi pakan dan performa pakan, serta mengetahui tingkat kebutuhan pakan benih ikan jurung (Tor soro) setelah periode 2-3 hari. Informasi yang diperoleh meliputi bobot mutlak, panjang mutlak dan kelangsungan hidup (SR) serta kualitas air. Penelitian ini dilaksanakan di Laboratorium Produksi Sekolah Tinggi Perikanan dan Kelautan Matauli pada bulan Juli-September 2024. Metode yang digunakan yaitu metode eksperimental dengan rancangan percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Ikan yang diuji adalah benih ikan jurung berukuran 3-5 cm. dengan durasi rata-rata 1,60±0,00 cm dan rata-rata berat 2,16±0,23g. Pemberian pakan diberikan pada pukul 08.00-08.10, 12.00-12.10, dan pukul 16.00-16.10. Ikan tersebut dipelihara dengan padat tebar 15 ekor. Hasil penelitian menunjukkan bahwa pendekatan pemberian pakan memberikan pengaruh yang besar (P<0,05) terhadap panjang mutlak, bobot mutlak, namun tidak berpengaruh nyata (P>0,05)  terhadap kelangsungan hidup. Perlakuan P1 memberikan hasil bobot mutlak sebesar 2.16 ± 0.23c, panjang mutlak 1.60 ± 0.00c dan kelangsungan hidup hingga 93.33 % yang merupakan perlakuan tertinggi dari perlakuan yang dilakukan

Abstract

Mangrove forests have an important role in reducing the impact of global warming as a place to absorb carbon dioxide (CO2) from the atmosphere which is mostly stored in sediment. Mangroves are a good habitat for aquatic biota such as macrozoobenthos. Macrozoobenthos are organisms that inhabit the bottom of sea waters and also exist in stable sediments. The aim of this research is to determine sediment texture, sediment organic carbon content, macrozoobenthos abundance and the relationship between sediment type and macrozoobenthos abundance. The method used in sampling was purposive sampling with a total of 3 stations. Sediment samples were taken using a core sampler at depths of 0-10 cm, 10-20 cm and 20-30 cm, while macrozoobenthos samples were taken using the hand sorting method. Organic carbon content was analyzed using the Loss on Ignition (LOI) method. The research results showed that the macrozoobenthos community structure at all stations produced low diversity and dominance indices and high uniformity indices.   The type of sediment texture in the research area shows an average value of the sediment fraction of 4.43% sand, 71.11% dust and 24.45% clay. The highest organic carbon content was found at stations near brackish water areas with an average of 12.06%, while stations near factory areas had the lowest content at 5.89%. There is a strong relationship between the type of sediment texture and the abundance of macrozoobenthos in the Karangtalun mangrove area, North Cilacap.

Abstract

The Bojongsoang Wastewater Treatment Plant (IPAL) in Bojongsoang District, Bandung Regency, West Java, is a facility that processes wastewater from the city of Bandung. In the IPAL pond, there are Nile tilapia that live there and can serve as bioindicators of water quality. However, these fish are utilized by the surrounding community through fishing and netting for consumption and sale. This study aims to determine the safety level of Nile tilapia (Oreochromis niloticus) meat in the Bojongsoang IPAL based on the content of heavy metals Cu and Zn. The research was conducted from May to October 2024. The method used is a survey method with purposive sampling technique conducted at four pond sample collection locations. The accumulated heavy metal content in the Nile tilapia meat from the Bojongsoang IPAL Treatment Pond is as follows: Cu (0.1649 mg/kg, 0.1199 mg/kg, 0.1896 mg/kg, 0.1825 mg/kg) and Zn (2.5308 mg/kg, 1.9651 mg/kg, 2.3628 mg/kg, 2.5125 mg/kg). The levels of these heavy metals are still below the maximum limits set by Ditjen POM RI in 1989, indicating that the Nile tilapia meat collected from the Bojongsoang IPAL Treatment Pond is still safe for consumption based on its Cu and Zn heavy metal content.

Abstract

Saleh Bay is a region in West Nusa Tenggara Province known for its significant marine resource potential, on which most coastal communities rely for their livelihoods. One of the most important activities for these communities is seaweed cultivation. Besides supporting the local economy, this activity has also made West Nusa Tenggara one of the largest seaweed producers in Indonesia. However, declining water quality has led to a decrease in seaweed production. This issue has occurred in certain areas of Saleh Bay, such as Labuhan Sangoro. This decline commonly happens during specific seasons (the rainy season) and as a result of ice-ice disease. Monitoring water conditions is essential to provide a reference for seaweed farmers on the water quality in their cultivation areas. This study was conducted in February 2024, coinciding with the rainy season. Water sampling was carried out using purposive sampling at six stations, which were cultivation locations (sampling stations from the previous year). Measurements of seawater chemical and physical parameters were conducted in situ and at the Lombok Marine Aquaculture Center Laboratory. The data obtained from these measurements were then analyzed descriptively using the Pollution Index method based on the Indonesian Minister of Environment’s Decree No. 115 of 2003. The Pollution Index evaluation indicated that in February 2024, the waters of Labuhan Sangoro remained at a moderate pollution level (PI=6.1), with some stations showing parameter values exceeding the quality standards.

Abstract

Vannamei shrimp, with its several advantages, is an essential export item for Indonesia. Polyculture technique has demonstrated efficacy in augmenting the growth and efficiency of shrimp production, with output consistently rising. In a polyculture system, green mussels function as biofilters and may assimilate organic materials. This study aims to elucidate the impact of green mussel biofilters on the development of Vannamei shrimp inside a polyculture system. This study was executed over a span of 21 days utilizing a Completely Randomized Design (CRD), incorporating three treatments with three replications, which included varying quantities of green mussels (10, 20, and 30 people) with 10 milkfish, 10 Vannamei shrimp, and 250 g of seaweed. The parameters measured were lead (Pb) concentrations in water, soil, and shrimp, along with the absolute lengths of the cephalothorax, abdomen, and overall length of the shrimp. The findings demonstrated that 20 green mussels were the optimal choice for the growth of Vannamei shrimp, despite the absence of statistically significant differences. In the treatment with 30 green mussels, the lead concentration dropped to 0.06 mg/L in water and 0.62 mg/L in soil, however the minimum lead concentration in shrimp was seen in the treatment with 10 green mussels (0.12 mg/kg).

Abstract

Green seaweed (Ulva reticulata) is found in many parts of Indonesia. The potential of green seaweed is not widely known to the public, even though it is considered a parasite on other types of seaweed. The purpose of this study was to determine the antibacterial compounds contained in green seaweed and their effectiveness against Vibrio parahaemolyticus bacteria. Green seaweed was extracted by maceration method and then qualitative and quantitative tests were carried out. After that, the minimum inhibitory concentration test was carried out and continued with the minimum bactericidal concentration test and the inhibition test with 5 treatments and 3 replications. The data from the qualitative and quantitative test of seaweed, the minimum inhibitory concentration and the minimum bactericidal were analyzed descriptively, while the data from the inhibition zone test was analyzed statistically by ANOVA. The results of qualitative and quantitative tests showed that green seaweed contained flavonoids (6.4909 mg/g), tannins (70.7500 mg/g) and saponins (443.7286 mg/g). The results of the minimum inhibitory concentration test showed that the concentration of 3.125% was the minimum concentration to inhibit bacterial growth. In the inhibition test, it can be seen that P4 (6%) is the best treatment. The results of statistical analysis show that the treatments given are significantly different, except that P4 (6%) and P5 (7,5%) are not significantly different. From this study it can be concluded that green seaweed extract is effective in inhibiting the growth of Vibrio parahaemolyticus bacteria.

Abstract

Lake Ranau as a water resource for the community, especially Warkuk Ranau Selatan District, has a fairly high biodiversity. Zooplankton is one of the biological components that functions as an indicator of water quality based on the composition and abundance of zooplankton. This study aimed to analyze the composition of genus and abundance of zooplankton in Lake Ranau, focusing on upstream, midstream, and downstream regions to identify potential differences in zooplankton diversity and density across these areas, potentially influenced by environmental factors such as water quality variation. The data collection method was carried out by sampling surface water and filtered using a plankton net tool. The results showed that the highest genus composition was observed at upstream lake and the highest abundance of zooplankton was found at midstream lake. The results of this study can be concluded that the distribution of zooplankton is not only influenced by biological factors but also by environmental conditions in each location so that the composition and abundance of zooplankton in Lake Ranau varies significantly between the upstream, midstream, and downstream areas.

Abstract

One of the causes of low growth and survival in the early development of larvae that still rely on food from natural feed is the availability of feed. The purpose of this study was to analyze the percentage level of increase in the density of the amount of natural feed cultured in Erlenmeyer media with different volumes of culture media. Completely Randomized Design with 3 treatments and 5 replications. The treatments used were 500 ml, 1000 ml and 5000 ml culture media volumes. The results of the study showed that the 500 ml volume culture media produced a density increase of 20%, then for the 1000 ml volume culture media it produced a density increase of 16% and for the 5000 ml volume culture media it produced an increase in density of 8%. So that with a 500 ml volume culture media it can effectively increase the density of I. galbana.

Abstract

Vaname shrimp remains a prime commodity due to several advantages, including the ability to thrive in a salinity range of 0.5-31 ppt, with a stocking density of 100-300 individuals/m², a faster growth cycle of 90-100 days, and a high appetite leading to rapid growth. Currently, the technology for culturing vaname shrimp has advanced with the implementation of intensive systems that utilize high stocking densities, although this impacts water quality. One approach to maintaining good water quality, especially in reducing organic waste, is the use of prebiotics and probiotics. Further studies are needed to determine the productivity of vaname shrimp with the addition of probiotics and prebiotics in shrimp culture. This research employed a survey method with parameters observed including productivity and water quality. Productivity encompassed stocking density, Average Body Weight (ABW), Average Daily Growth (ADG), population, biomass, Food Conversion Rate (FCR), Survival Rate (SR), and size. Water quality parameters measured included salinity, temperature, pH, DO using a Multitester, alkalinity, TOM, Ca, Mg, Total Hardness using titration, PO4, NH4, NO3, NO2 using a test kit, the number of green algae, blue-green algae, diatoms, euglena, and dinoflagellates using a hemocytometer, zooplankton, and protozoa using a Sedgewick Rafter, total bacteria, total vibrio, and the number of yellow, green, and black vibrio using Total Plate Count (TPC). Data analysis used descriptive methods. The results showed that the harvest exceeded the company's target, and the SR and FCR values were categorized as good in vaname shrimp cultivation. Water quality measurements indicated that conditions were still optimal for vaname shrimp culture.
