Abstract

The rise of the world of ornamental fish in Indonesia has become a business opportunity for various groups. One of them is the ornamental snakehead fish or Channa pulchra. This fish comes from Myanmar and was imported to Indonesia to meet the needs of the ornamental fish market. One of the factors that influence the success of a fish farming business is the FCR and SR values. The lower the FCR value and the higher the SR value, the better the sustainability of the cultivation business. To maintain FCR and SR values, a good quality feed supply is needed. The aim of this research is to determine the effectiveness of supplementing pelleted feed in the form of Spirulina flour and butterfly pea flower flour (Clitoria ternatea), which contain nutrients to support growth and immunity so that they can improve FCR and SR values. The methods used in this research are quantitative and experimental methods. The experimental design used was a completely randomized design (CRD) with 12 containers filled with 1 fish/container. Data were analyzed using the ANOVA test which was carried out with Duncan's advanced test. Observation parameters include FCR value, SR value and water quality. The results obtained showed that there was an effect of providing different additional feeds on the FCR value with the best treatment being treatment A with a value of 3.6 ± 0.61. Treatment B has a value of 5.35 ± 0.21 and treatment K has a value of 4.05 ± 0.53. Meanwhile, the SR value does not show any influence from providing additional feed which is different from the value of 100% for each treatment parameter. Water quality results include a salinity value of 0 ppt, DO 7.16 ± 0.68 mg/l and temperature 29.62 ± 0.82 °C. The water quality value is still considered safe for cultivation unless the temperature is too high which is thought to influence fluctuations in the FCR value.

Abstract

Freshwater lobster (Cherax quadricarinatus) is one of the freshwater commodities that has the potential to be cultivated and has economic value. However, the problem still faced by farmers is the quality of feed which can affect low growth and survival. This research aims to analyze the growth performance of juvenile lobsters fed silk worms and rice flour. This research used 30 juvenile lobster samples measuring 1-3 cm (+ 1 inch) that were around 30 days old per aquarium. The parameters observed were body length, body weight, and survival rate (SR) of juvenile lobsters and the water parameters measured were pH, temperature, and total dissolved solids (TDS). The results of the research show that juvenile freshwater lobsters are able to consume silk worms and rice flour so that juvenile lobsters can be classified as omnivores. Feeding treatment in the form of a combination of silk worms and rice flour showed the best results for growth in length, weight and SR of juvenile freshwater lobsters. Juvenile growth during 32 days of rearing fed a combination of silkworm and rice flour resulted 4.30 cm + 0.02 cm in a length, 1.43 g + 0.01 g in weight, and SR 80%.

Abstract

Daphnia sp is a small aquatic organism that is rich in nutrients and is generally used as a potential natural food because of its high nutritional content. Challenges in fish farming arise because the availability of Daphnia sp is not always stable. As an alternative solution, tofu dregs and ginger extract are used as a source of protein and nutrition for Daphnia sp. Tofu dregs contain protein from soybean starch, while ginger extract contains immunostimulants. This study aims to evaluate the population density and growth rate of Daphnia sp by using media with tofu dregs and ginger extract with certain variations in composition. This research was carried out in Gopaan Sembunganyar Dukun-Gresik Hamlet in April-May 2024. The research method used was an experimental approach with a Completely Randomized Design (RAL), consisting of 3 treatments which were repeated 3 times, so that a total of 9 experimental units were obtained. Each treatment used a water volume of 8 liters with a Daphnia density of 20 individuals per liter. The parameters observed were temperature, pH, amonia, protein, fat and carbohydrate concentrations. The research results showed that the activity of providing Tofu Dregs and Ginger Extract had a significant influence on population density and growth of Daphnia sp. Treatment P2 showed the highest results with a density reaching 2653 ind.Lˉ¹, growth rate of 33.17%, protein content of 33.17%, fat content of 8.99%, and carbohydrate content of 53.36%.

Abstract

The presence of microplastics in the environment has generated global concerns. Microplastics contamination is a global environmental problem which negative effect in a habitat, include waters and can enter the food chain that contribute to human health. Occurrence of microplastics in the environment affected by intensive anthropogenic activities, one of them is tourism activity. This study aimed to determine the types and the abundance of microplastics at Temberan Beach, Bangka Regency, Bangka Belitung Archipelago Province. The water samples were taken using a plankton net (mesh size 100 / 150 µm) with diameter 15 cm and 1,5 L of the surface of the water was analyzed the microplatics content. The microplasctics analysis was carried out by oxidative digestion of organic matters method which are utilizing hydrogen peroxide (H2O2). The results showed there were four types of microplastics and their abundance, namely fiber (54%), foam (26%), fragment (15%), and film (5%). We have observed that anthropogenic activity contributed to microplastic abundance.

Abstract

Parosphromenus deissneri is a freshwater species known exclusively from Bangka Island, Indonesia. According to the IUCN Red List of Threatened Species in 2020, this species is endangered, and the population continues to decrease due to the consequences of open-pit tin mining on Bangka Island harming its natural ecosystem. Despite the fact that this species is regarded as endangered, no known conservation and domestication initiatives have been made to enhance its number in the wild. In this study, we propose to do domestication of P. deissneri using biotope principles and techniques to increase the P. deissneri capacity for adaptation and reproduction since these species believe they are in their natural habitat. This study was carried out from April to September of 2023 at Bangka Belitung Endemic Fish Laboratory. We designed the biotope concept using an aquarium with dimensions 200 cm x 100 cm x 50cm. Biotopes are equipped with aquatic plants, roots, twigs, dead leaves, sand, rocks, gravel, and water containing natural plankton as biotic and abiotic elements. In this study, a Parosphromenus deissneri broodstock of 20 individuals (10 males and 10 females) was maintained for a 5-month period, resulting in an 80% survival rate. During the study, one mating pair successfully produced approximately 14 eggs, 8 of which hatched. Following a 2-month larval development phase, 4 fry survived to adulthood, yielding a survival rate of 25% relative to the total number of hatched eggs. These results underscore the necessity for refined husbandry practices and optimal environmental conditions to improve fry survival and enhance reproductive success in future breeding efforts.

Abstract

Penelitian bertujuan untuk menguji aktivitas antibakteri ekstrak Eucheuma cottonii terhadap Streptococcus mutans menggunakan metode difusi cakram. Streptococcus mutans merupakan penyebab utama karies gigi, dan pemanfaatan bahan alam seperti alga merah dapat menjadi alternatif pengganti antibiotik sintetis. Sampel Eucheuma cottonii yang diperoleh dari Pesisir Desa Ruguk, Lampung Selatan, dimaserasi dengan pelarut metanol, kemudian diekstraksi menggunakan metode rotary evaporator dan water bath. Ekstrak diuji pada berbagai konsentrasi (10.000, 5.000, 1.000, 100, 10 ppm) untuk mengukur zona hambat terhadap bakteri uji. Hasil menunjukkan bahwa metode water bath menghasilkan zona hambat maksimal sebesar 2 mm pada konsentrasi 10.000 ppm dalam 24 jam pertama, tetapi efek antibakteri melemah seiring waktu. Metode rotary evaporator menunjukkan hasil yang berfluktuasi, dengan zona hambat terbesar pada konsentrasi 5.000 ppm sebesar 0,90 mm dan anomali pada konsentrasi rendah setelah inkubasi lebih lama. Secara keseluruhan, aktivitas antibakteri tergolong lemah (<5 mm), menunjukkan sifat bakteriostatik, yakni menghambat pertumbuhan tanpa membunuh bakteri secara permanen. Metode water bath lebih unggul dalam menghasilkan ekstrak yang stabil dengan aktivitas antibakteri konsisten dibandingkan rotary evaporator. Penelitian ini menyimpulkan bahwa ekstrak Eucheuma cottonii memiliki potensi antibakteri, tetapi optimasi lebih lanjut diperlukan untuk meningkatkan efektivitasnya terhadap Streptococcus mutans.

Abstract

Kelabau is a species of indigenous fish from Kalimantan and Sumatra that is now rarely found in rivers. This is due to the fishing by fishermen who are less selective for years without being balanced with cultivation efforts. Cultivations have several aspects that need to be considered, namely the availability of feed that contains good nutrients and is in accordance with the needs of fish. Kelakai is an alternative that can be used as additional feed for kelabau. the use of the biofloc system is also rarely done in kelabau farming. The combination of kelakai leaf silage and biofloc system has the potential to increase the efficiency of kelabau farming by applying environmentally friendly technology. The study aims to analyze the growth performance of kelabau. The research was carried out in the Wet Laboratory located at the Faculty of Fisheries and Marine Science, Lambung Mangkurat University, Banjarbaru City, South Kalimantan Province. The research method used was an experimental approach with a Completely Randomized Design (RAL), consisting of 3 treatments which were repeated 3 times, so that a total of 9 experimental units were obtained, where Treatment K (Control) is commercial feed given at a dose of 5% of biomass weight, Treatment A is kelakai leaf silage at a dose of 5% of biomass weight, and Treatment B is commercial feed + kelakai leaf silage at a dose of 2.5% of biomass weight. The research results showed the best results in relative length of 121.5%, relative weight of 24.0%, and feed utilization efficiency of 47.3%. FCR showed the best results in treatment K of 0.68% and the best survival rate in treatments K and A of 99.3%. Treatment B can be considered as an alternative feed for the cultivation of kelabau in biofloc systems because it can improve growth performance.

Abstract

Cumi Bangka (Uroteuthis chinensis) merupakan komdoditas perikanan yang memiliki nilai ekonimis yang tinggi dan salah satu komoditas unggulan strategis dalam sektor perikanan dan kelautan karena memiliki kualitas terbaik di pasar ekspor. Namun dikarenakan eksploitasi penangkapan cumi-cumi yang berlebihan, dan rusaknya habitat penempelan telur, sekaligus habitat pemijahan cumi-cumi akibat berbagai aktivitas teresterial, khususnya aktivitas penambangan pasir timah laut, menjadikan jumlah tangkapan cumi Bangka jauh menurun. Perubahan iklim global yang ekstrim, juga menjadi pemicu berkurangnya jumlah cumi di alam. Penelitian ini bertujuan untuk mempelajari perubahan morfologi telur cumi Bangka (U. Chinensis) sebelum menetas dan mengukur survival rate larva cumi pasca menetas, yang diberikan pakan buatan dan pakan egg custard di modifikasi. Pengamatan morfologi dilakukan secara langsung setiap 24 jam, sejak diambil dari alam samapi menetas di bak pemeliharaan. Dengan mengamati perubahan bentuk morfologi, bobot dan panjang telur. Selanjutnya pemberian pakan buatan dan egg custard di modifikasi setelah telur menetas diberikan lima kali dalam sehari, yakni pada jam 07.00 pagi, jam 11.00 siang, jam 15.00 sore, jam 19.00 malam, 23.00 malam. Hasilnya menunjukkan bahwa, dimedia tetas dibutuhkan waktu 6-9 hari bagi telur cumi untuk menetas. Setiap hari terjadi perubahan morfologi telur yang semakin membesar dan pemisahan jonjot yang jelas disetiap kapsul telur. Hatching Rate cumi mencapai 65,40 %, pada salinitas 31-35 ppt. Pemberian tiga jenis pakan buatan, yakni Otohime B2, Feng-Li 0 dan Scretting Stella B-2 mampu membuat larva cumi bertahan selama 3 dan 4 hari. Pemberian pakan tiga jenis egg custard di modifikasi hanya mampu membuat larva cumi bertahan selama 4 dan 5 hari.
