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

Potensi besar dalam budidaya ikan air tawar seperti nila (Oreochromis niloticus) dan lele (Clarias sp.) ada pada Kabupaten Gresik, khususnya Kecamatan Sidayu. Namun, budidaya ikan khususnya di kolam tanah tradisional masih menghadapi kendala seperti rendahnya efisiensi pakan, fluktuasi kualitas air, serta serangan penyakit. Salah satu solusi yang menjanjikan adalah sistem polikultur, yaitu membudidayakan kedua spesies secara bersamaan untuk menciptakan ekosistem yang lebih seimbang. Penelitian ini bertujuan menentukan rasio tebar ideal, pengelolaan kualitas air, serta pengaruh polikultur terhadap pertumbuhan dan kelangsungan hidup ikan. Metode penelitian menggunakan pendekatan kuantitatif dengan variasi rasio tebar nila dan lele di tambak tradisional. Parameter yang diamati meliputi pertumbuhan berat ikan, survival rate, kualitas air, dan FCR. Data dianalisis secara deskriptif. Sistem polikultur memanfaatkan relung ekologis yang berbeda, mengurangi kompetisi sumber daya dan menjaga kualitas air secara alami. Hal ini meningkatkan produktivitas tambak serta ketahanan terhadap perubahan lingkungan. Penelitian ini membuktikan bahwa polikultur nila dan lele merupakan alternatif efektif dalam meningkatkan efisiensi produksi dan keberlanjutan budidaya ikan di kolam tanah tradisional. Kesimpulannya Sistem polikultur nila-lele di kolam tanah tradisional Sidayu, Gresik, berpotensi besar dikembangkan dengan rasio tebar optimal 100:0 (nila:lele). Hasilnya, pertumbuhan nila mencapai 692.000 gram dengan survival rate 88% dan FCR 1,8 yang memenuhi standar FAO. Polikultur ini meningkatkan produktivitas tambak, memanfaatkan relung ekologis berbeda, dan mengurangi kompetisi sumber daya dibanding monokultur.

Abstract

Budidaya udang vaname (Litopenaeus vannamei) merupakan salah satu subsektor perikanan yang memiliki nilai ekonomi tinggi dan berperan penting dalam mendukung perekonomian masyarakat, Budidaya udang  merupakan salah satu kegiatan perikanan budidaya yang banyak dikembangkan di Indonesia, Di antara berbagai sistem budidaya, tambak tradisional masih menjadi pilihan utama bagi sebagian besar petambak, terutama mereka yang memiliki keterbatasan modal dan teknologi. Sistem tradisional umumnya dilakukan dengan input rendah, memanfaatkan kondisi lingkungan alami tanpa pengelolaan intensif, sehingga memiliki biaya operasional yang relatif murah namun dengan produktivitas yang terbatas, Penelitian ini bertujuan untuk menganalisis pertumbuhan bobot dan laju pertumbuhan bobot harian dari udang vanname yang dibudidayakan ditambak tanah secara tradisional, Penelitian ini dilakukan pada dua tambak yang menjadi sentra budidaya udang tambak tanah tradisional, Penelitian ini dilaksanakan selama satu bulan, dari bulan Maret - April 2025, variabel dari penelitian ini mencakup bobot mutlak dan panjang mutlak dari udang yang dibudidayakan, Data hasil penelitian dianalisis menggunakan Microsoft Excel 2016, yang kemudian dianalisis, Penelitian ini menunjukan hasil bahwa tambak udang II menunjukkan hasil yang lebih baik, dimana memiliki bobot mutlak udang sebesar 3.8 gram dengan laju pertumbuhan harian sebesar 0,12,67% bb/hari, Nilai ini lebih besar jika dibandingkan dengan udang yang dipelihara pada tambak udang I, yang memiliki bobot mutlak udang sebesar 3.6 gram, dan laju pertumbuhan harian sebesar 0,12%bb/hari, Terdapat perbedaan perlakuan yang berbeda pada kedua  tambak. Kepadatan serta pemberian pakan yang tidak optimal menjadi salah satu penyebab pertumbuhan yang lambat, sebaliknya luas lahan dan kepadatan yg optimal lebih mengguntungkan untuk udang dalam memperoleh pakan alami.

Abstract

Decorative fish is a significant fishery product since it tends to be finished by exporters, one of the elaborate fish that adjusts to be sent out is manfish on the grounds that it has the excellence of variety and agile developments. The growth of manfish can be influenced by appropriate feed, so this study aims to find out what type of natural feed is suitable for the growth of manfish with artificial feed comparisons (pellets). The treatments used in this study were 100% artificial feed (petet) as control/P0, 100% Daphnia sp as 1/P1 treatment, 100% Tubifex as 2/P2 treatment, and 50% Daphnia sp and 50% Tubifex as 3/P3 treatment. The parameters observed during the study were absolute weight growth, absolute length growth, survival rate,  water quality, and feed conversion ratio. The results showed a treatment that used good natural feed in the long growth of manfish, namely P1 treatment of 100% Daphnia sp feed by showing a figure of 5.27±0.29 cm. The absolute weight growth parameters in good natural feed treatment are P1 treatment of 100% Daphnia sp with a figure of 3.20±0.34 g. The results of the study with feed conversion ratio parameters in natural feed treatment showed the results that P1 treatment experienced high fish appetite because feed needs during the study showed a figure of 11454.02 mg. The lowest survival rate was obtained in the control at 66.67% and the highest survival rate at P1 treatment at 91.67%. The measured water quality parameters are temperature, pH, salinity, and dissolved oxygen which each show numbers in the range of 27-17oC, 00/00, 7-8 and 4-5mg/L.

Abstract

White shrimp (Litopenaeus vannamei) is an important aquaculture commodity with production demand that continues to increase every year. The addition of chitosan from green mussel shells in feed can increase calcium availability, support the moulting process, and increase shrimp growth and survival. This study aims to examine the effectiveness of green mussel chitosan supplements on the growth and survival of vaname shrimp. This research consists of three stages, namely making chitosan nanoparticles from green mussel shells, making feed with various doses of chitosan nanoparticles (0%/A, 10%/B, 15%/C, and 20%/D), and cultivating vaname shrimp. Feed is made by mixing chitosan nanoparticles with commercial feed, then drying and crushing it into small crumbs. White vaname shrimp are kept in concrete ponds for 80 days, with water quality monitoring and regular measurements of growth in weight and length. Data shows that C treatment with a dose of 15% chitosan nanoparticles resulted in the highest growth in weight and length of vanamei shrimp, reaching an average weight of 12.58 grams and a length of 14.07 cm on the 80th day. Treatment C provides optimal growth compared to other treatments because chitosan accelerates the moulting process and exoskeleton mineralization. Water quality during the study, including a temperature of 29.99°C, pH 7.23, and ammonia content of 0.25 ppm, was within the tolerable range for shrimp growth.

Abstract

Koi fish, a popular freshwater ornamental fish with high economic value, is known for its attractive shape and color. Intensive cultivation of koi (Cyprinus rubrofuscus) using sistems such as Recirculatory Aquaculture Sistem (RAS) and aquaponics presents profitable business opportunities. However, land conversion for development reduces cultivation areas and water quality, necessitating innovations to ensure the sustainability of fish farming. The RAS sistem utilizes filters to recycle water, while aquaponics uses plant media for filtration. Research conducted from February 7 to March 19, 2024, at UD. Pojok Koi Farm, Gresik, East Java, aimed to compare koi growth under these two cultivation sistems. The results indicate that neither the aquaponics sistem nor RAS significantly affected koi length and survival, but both had an impact on weight gain and feed conversion ratio (FCR). Water quality, including pH, temperature, and DO, plays a crucial role in koi growth. pH and temperature remained within suitable ranges, while DO levels met the minimal requirements for koi in both sistems. Good water quality and effective filtration sistems support the growth and health of koi fish.

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

Indonesian imports of gelatin and collagen raw materials totaled 4808 tons. Gresik is one of the producers of milkfish in East Java, with 87116 tons expected in 2022. Even though it contains type 1 collagen, milkfish bone waste that is not used at the center for making milkfish brains is an environmental hazard. Given this possibility, this study aimed to determine the qualitative characteristics of collagen extract from milkfish bone debris (Chanos chanos) with and without the addition of Ca2+ of varying quantities. The extraction method employs the enzyme bromelain 2% and cofactor metal ion Ca2+ (0.5%; 1.0%; 1.5%), which has previously been pre-treated in the form of defatting and deproteination, before determining physical and chemical properties. The results showed that using bromelain enzyme with Ca2+ boosted collagen yield. Adding 0.5% Ca2+ resulted in the highest yield, 7.58±1.88%. All collagen produced contains functional groups recognized in FTIR as type 1 collagen constituents (presence of amide A, amide B, amide I-III). The melting point of the collagen generated is between 144 and 157 °C. The SEM profile of collagen was porous sheets in all treatments. Except for the ash content, the chemical properties of collagen generated by adding the Ca2+ (pH 7.49-8.09; water content 7.75-8.15; ash content 6.56-7.78) fulfill SNI and BSP standards. Meanwhile, collagen synthesized without the inclusion of cofactors only meets the water content standards (pH 7.49-8.09; water content 7.75-8.15; ash content 6.56-7.78). The demineralization stage is required to produce milkfish bone debris before extraction to achieve these requirements.
