Abstract

Ikan Cempedik (Osteochilus spilurus) merupakan salah satu ikan konsumsi ekonomis penting bagi masyarakat Belitung Timur. Ketersediaannya untuk konsumsi dan perdagangan masih mengandalkan hasil tangkapan dari alam. Penangkapan alam secara terus menerus dapat berakibat terjadinya penurunan populasi Ikan Cempedik pada habibat alaminya, sehingga perlu adanya upaya mendomestikasi spesies ini menuju komoditas akuakultur. Ikan air tawar ini telah berhasil didomestikasikan pada level pertama dengan kemampuannya hidup dalam wadah terkontrol, pada penelitian ini diupayakan meningkatkan kematangan gonadnya melalui pakan yang mengandung hormon GnRH-Analog+Antidopamin. Penelitian ini terdiri dari 4 perlakuan yakni P1 (kontrol), P2 (0,005 ml/gram pakan), P3 (0,01 ml/gram pakan), dan P4 (0,015 ml/gram pakan). Hasil penelitian menunjukkan pemberian hormon GnRH-Analog dan Anti Dopamin melalui pakan memberikan pengaruh terhadap peningkatan nilai Gonado Somatic Index dan Hepato Somatic Index Ikan Cempedik. Perlakuan terbaik terdapat pada dosis 0,015 ml/gram yang menghasilkan TKG IV terbanyak, Gonado Somatic Index (GSI) sebesar 7,59%, Hepato Somatic Index (HSI) sebesar 0,17% dan fekunditas sebesar 1.390 butir.

Abstract

Green mussels (Perna viridis) in Banyu Urip Village, Ujung Pangkah Gresik District, have great potential to be developed due to the abundant availability of seeds in nature, easy cultivation methods, namely using floating net cages and step nets, and high market demand. One of the issues with green mussels is the high content of the heavy metal Lead (Pb) in their flesh, which is caused by heavy metal accumulation in the waters. The goal of this study was to isolate, characterize, and test the ability of heavy metal Lead-Pb bacteria to biosorb heavy metal Pb in post-harvest green mussels from sediments and green mussels in the Banyu urip Ujung Pangkah Gresik Sea. The stages of the research included sampling, isolation, macroscopic and microscopic characterization, in vitro testing of Pb heavy metal absorbent. The results showed 6 bacterial isolates, namely two from green mussels coded K1 and K2 and 4 bacterial isolates from marine sediments coded S1, S2, S3 and S4. The six bacterial isolates obtained macroscopic and microscopic characteristics and have been shown in vitro to be able to grow in Nutrient agar enriched 0.8 mg/L Pb(NO3)2.

Abstract

Anti-bacterial is a compound that can be used to inhibit bacterial growth. The compounds that play a role in damaging the cell membrane are phenols, flavonoids, and alkaloids. The phytochemical compounds above have the potential as natural Anti-bacterial on pathogenic bacteria, for example against Escherichia coli. Escherichia coli is a pathogenic microbe in humans that can cause digestive disorders and disrupt the work system of the stomach organs. Seagrass C. rotundata has compounds that are antibacterial, such as alkaloids, flavonoids, phenols, steroids, and tannins. C. rotundata can be seen in Indonesian waters. However, it has not been widely used. This study aims to determine the difference in concentration of seagrass extract of C. rotundata against E. coli anti-bacterial activity. The research method used was experimental laboratories with different concentrations of seagrass extract (10%, 20%, 30%, and 40%). The results showed that the seagrass extract of C. rotundata was effective as an antibacterial with a middle category, which is the inhibition zone ranging from 5-10 mm. Based on the studies conducted, 72 hours incubation period at 40% concentration was the best concentration to prevent E. coli at the 8.5 mm inhibition zone. Furthermore, bioactive compounds produced by C. rotundata are flavonoid compounds by showing changes in the color of the solution to yellow-orange. In addition, also produces phenol bioactive compounds by showing a change in the color of the solution to greenish, and also produces tannin bioactive compounds by showing a change in the color of the solution to blackish green. The results showed that C. rotundata can be used as a recommendation for the development of Anti-bacterial drugs in the future.

Abstract

Betta fish, one of freshwater ornamental fish aquaculture commodities which has high sale value. Betta fish has various pattern and unique fish fin shape. Cattapa dip was a fish health product consisting of catappa leaves and vitamin C. This product could be use for betta fish cultivation so as not to be attacked by parasites, fungi, bacteria and also for helping the process of betta fish color changing. Cattapa dip could also maintain the stability of the water pH in betta fish cultivation. This product has a shape resembling a tea bag product which is very attractive and unique. This study consisted of 4 treatments and 3 replications. The treatments given were Treatment A (0.3 gram of catappa leaves and 0.1 gram vitamin C), Treatment B (0.5 gram of catappa leaves and 0.1 gram of vitamin C), Treatment C (0.7 gram of catappa leaves and 0.1 gram of vitamin C) and K treatment / control (without treatment). The parameter observed during the study was the color change of Betta fish (Betta sp) which was measured by the percentage of color change based on RGB (Red Green Blue) using the Color Picker application. The results showed that the treatment with the addition of Kataplus in the form of dip as much as 0.5 gram of ketapang leaves and 0.1 gram of vitamin C was the best treatment. Based on the results of the color changes that occur in treatments A, B, C with 3 color indicators namely Green (green), Red (red), and Blue (blue). Color changes occurred in weeks 1st to week 4th where the best were obtained in treatment B with the average percentage produced, namely Red of 125,975%, Green of 111,375% and Blue of 116,6%. So it could be conclude that the use of Cattapa dip has an effect on color changes in Betta fish (Betta sp).

Abstract

Encheloclarias tapeinopterus is an endemic catfish found only from Bangka Island, Indonesia. This species is listed as a Vulnerable species based on the IUCN Red List, which means that the population of this species has decreased drastically over time, and it is possible that this species will become extinct in the near future if there are no efforts to save the species. Until now, there have been no reports regarding domestication and conservation efforts for this species. In addition, there has been no socialization and punishment given to people who catch this species. Society can freely catch E. tapeinopterus without any punishment or deterrent effect. Theoretically, Indonesia actually has a Conservation Law, namely Law Number 5 of 1990 concerning Conservation of Biodiversity and Its Ecosystems which provides protection for biodiversity. However, this law talks more about the conservation system than providing legal protection for wild animals and their habitats. Based on this, the legal protection of wild animals in Indonesia needs to be improved. In this article, we describe legal certainty if Indonesia can adopt the American Wildlife Protection law "The Endangered Species Act (Esa)" in the framework of efforts to protect the endemic fish Encheloclarias Tapeinopterus which has a vulnerable status. In this paper we compare Law Number 5 of 1990 and The Endangered Species Act law.

Abstract

Salah satu jenis ikan seluang yang banyak ditemukan di perairan Bangka Belitung yaitu Brevibora dorsiocellata. Ikan ini berpotensi untuk dikembangkan sebagai ikan salah satu ikan hias lokal. Budidaya ikan Seluang (B. dorsiocellata) saat ini masih belum banyak dilakukan dikarenakan terbatasnya informasi dalam kegiatan domestikasi. Penelitian ini bertujuan mengevaluasi dan menentukan kisaran suhu optimum untuk kelangsungan hidup, pertumbuhan dan tingkat konsumsi oksigen ikan Seluang (B. dorsiocellata) yang dipelihara pada suhu yang berbeda di wadah budidaya pada tahap awal domestikasi. Penelitian dilaksanakan pada bulan Februari sampai dengan Maret 2021 berlokasi di Laboratorium Akuakultur, di Universitas Bangka Belitung. Metode penelitian yang digunakan yaitu metode eksperimental dengan 4 perbedaan suhu yaitu Kontrol (suhu ruang), suhu 27oC, 29oC dan 31oC. Parameter yang diamati pada penelitian ini yaitu kelangsungan hidup ikan, laju pertumbuhan spesifik, laju pertumbuhan mutlak, efisiensi pakan, tingkat konsumsi oksigen dan kualitas air selain suhu sebagai data pendukung. Hasil penelitian menunjukkan bahwa suhu berpengaruh berpengaruh terhadap pertumbuhan panjang mutlak ikan seluang selama pemeliharaan namun tidak berpengaruh nyata terhadap laju pertumbuhan spesifik, panjang bobot mutlak dan efisiensi pakan. Suhu 31oC memberikan pengaruh nyata terhadap pertumbuhan panjang mutlak sebesar 0,31±0,04 cm dibandingkan P1 (Kontrol), P2 (27oC), P3 (29oC) dengan nilai laju pertumbuhan spesifik 0,57±0,26% dan efisiensi pakan sebesar 2,77±1,17%. Suhu 27oC merupakan perlakuan dengan tingkat konsumsi oksigen terendah yakni sebesar 0,05 mg O2/menit. Sedangkan suhu 31oC merupakan perlakuan dengan tingkat konsumsi oksigen tertinggi sebesar 0,081 mg O2/menit. Berdasarkan hal tersebut, dapat disimpulkan bahwa kisaran suhu pemeliharaan untuk kelangsungan hidup dan pertumbuhan pada ikan Seluang (B. dorsiocellata) yaitu pada suhu 27-29oC dengan tingkat konsumsi oksigen yang normal.

Abstract

Squid (Loligo sp) is one of the most essential fishery commodities and ranks third after fish and shrimp in commercial fisheries. The freshness of the squid is a very important factor and is closely related to its economic value. One of the actors in the marine commodity storage business at Rebo Beach, Bangka Regency uses Cucumbers to maintain the quality of Squid. Until now there has been no scientific research that proves that Cucumber can be used as a preservative for Squid. For this reason, it is necessary to research to examine the effect of using cucumber at different concentrations and soaking times on the organoleptic assessment of squid quality. This research was conducted in February 2020. The handling process for the Squid was carried out at the Squid shelter in Baturusa, Merawang District, Bangka Regency. In contrast, the organoleptic tests were carried out at the Aquaculture Laboratory of the University of Bangka Belitung. The research was conducted by experimental method. The research variables were differences in the concentration of grated Cucumber and differences in the length of soaking Squid. This study used RAL (Completely Randomized Design) Factorial pattern with 2 factors and 3 replications. Treatment factor by giving grated Cucumber and control or using ice cubes at different times and doses. The soaking times in this study were 24 hours and 48 hours with grated cucumber measurements of 50, 100, and 150 grams per 5 liters of water. Data analysis in this study used the Kruskarwalis test. Squid treated with grated cucumber had the same brightness level as ice cubes after 24 hours of soaking. Giving grated Cucumber does not affect the taste and texture of Squid to the level of people's preferences. Giving grated Cucumber as much as 150 g with 24 hours of soaking time can be accepted by consumers and can compete with Squid which is given ice cube treatment.
