Abstract

MOL (Local Microorganisms) is a solution resulting from fermentation from the decay of organic materials, the solution is useful to helping the process of decomposition of organic materials. MOL has the potential to be a bioactivator in fermentation. This study aims to analyze the abundance of Daphnia magna  populations  cultured on media with the addition of MOL with different doses. The research was carried out at the Fish Nutrition Laboratory, Faculty of Fisheries and Marine Sciences, Lambung Mangkurat University, Banjarbaru City, South Kalimantan Province. The MOL used comes from fermented vegetable waste of cabbage, cauliflower leaves and mustard greens that are fermented for 14 days. This study used a Complete Random Design (CRD) of 4 treatments and 3 replicates with a MOL dose of 0 mL/L (K), 0.5 mL/L (A), 1 mL/L (B), and 1.5 mL/L (C). The parameters observed were population abundance, population growth rate, maximum population growth  of Daphnia magna, and water quality. The study showed the best results in Treatment C, namely an abundance of 2453.33±68.06 ind/L, a growth rate of 51.44±0.134% and the maximum growth of the Daphnia magna population occurred on day 8. The results of the analysis of nutrient quality from MOL and the quality of culture media water are very supportive in the growth  of Daphnia magna. The application of MOL of vegetable waste fermented from cabbage, cauliflower leaves and mustard greens waste as much as 1.5 mL/L in culture media can be considered in the enrichment of culture media for the growth  of Daphnia magna.

Abstract

Microalgae is one of the microorganisms that has the potential as raw material in the development of research and technology to produce vegetable oil. Microalgae Spirulina sp. is a microalgae that has the potential to be used as a raw material for biodiesel, which has a fairly high lipid content when compared to other microalgae. However, to produce enough Spirulina sp. biomass, it is necessary to optimize the culture media.  One of the organic materials that can be used as Spirulina sp. culture media is vaname shrimp farming waste (Litopenaeus vannamei). This study aims to utilize vaname shrimp farming waste to minimize costs in mass-scale microalgae cultivation for daily lipid evaluation and biodiesel production. The method used in this study was laboratory experimental method, where observation and primary data collection were conducted on a mass scale. Based on the research results, the highest daily cultivation dry biomass of Spirulina sp. was found on day 4 (four) with a value of 2.29gr/L with a biomass percentage of 7.24%. The highest lipid extracted using soxhlet was on day 4 (four) with a lipid percentage value of 3.73% with a lipid percentage of 0.84% and the highest lipid productivity was also found on day 4 (four) with a value of 0.0854 gr/L. Mass cultivation biomass of Spirulina sp. obtained wet biomass of 13,760 g and dry biomass of 3,220 g. Lipid yield of Spirulina sp. in mass cultivation obtained a weight value of 163.74 g with a percentage of 5.09%. Biodiesel yield of Spirulina sp. in mass cultivation amounted to 101.225 g with a percentage of 61.82%. The quality of Spirulina sp. biodiesel consisted of 4 highest chemical compounds, namely Heptadecane (CAS) n-Heptadecane 41.35%, Hexadecanoid acid, methyl ester 13.03%, Isoppropyl Linoleate 8.91%, and 9,12-Octadecanoid acid (Z,Z)-, methyl ester 6.88%.

Abstract

This study aims to identify the community structure, conservation value, and habitat suitability of the ichthyofauna in the aquatic ecosystem of the Bumang River, Bangka Island. Exploration was conducted in June–August 2025 using a descriptive exploratory method through fishing with traps, gillnets, and scoop nets at three observation stations. The identification results showed that there were 41 fish species, one shrimp species, one freshwater crab species, and one snail species. Three of them are endemic species of Bangka Island, namely Betta chloropharynx, Parosphromenus bintan, and Betta schalleri. The diversity index (H’) value in the Bumang River ranged from 1.243–2.578 which indicates a moderate category, the evenness index (E) between 0.334–0.694, and the dominance index (C) between 0.114–0.403 which indicates the absence of dominant species. Water quality parameters indicate a temperature of 25–28°C, pH 5–6, and DO 3.7–6.5 mg/L, which are still suitable for freshwater fish life. The presence of several endemic and endangered species such as Betta schalleri (EN), Betta chloropharynx (CR), and Parosphromenus bintan (VU) demonstrates the importance of the Bumang River as an inland water conservation area with high ecological value. The results of this study are expected to become the basis for the sustainable management and protection of aquatic biodiversity on Bangka Island.

Abstract

Extremophilic fish require genetic characterization to determine the identity of their species, their kinship, and the potential for genetic variation due to extreme environmental adaptation. DNA barcoding using Fish-F2 and Fish-R2 primers at an annealing temperature of 52oC for 15 seconds showed qualitative failure results in most fish species. For this reason, optimizing the annealing temperature in the PCR process is necessary to obtain DNA bands that correlate with successful identification. Fish samples were obtained from Ruai Silip, Bangka Island, Membalong, Belitung Island, and Way Kanan, Lampung, Sumatra Island. The annealing temperature optimization was set at 50, 50.4, 51.1, 52.3, 53.7, 54.8, 55.5, and 56°C. Five species of extremophile fish were tested, namely Brevibora sp, Barbodes binotatus, Rasbora bankanensis, Anabas testudineus, and Aplocheilus panchax. Extremophile fish showed differences in the appearance of DNA bands in PCR with different annealing temperatures. Brevibora sp showed a visualization of DNA bands at 54.8°C, Barbodes binotatus at 53.7, 54.8, 55.5, and 56°C, Anabas testudineus at 50 and 50.4°C, and Aplocheilus panchax produced clearly visible band on annealing temperatures.

Abstract

The Selincah fish (Belontia hasselti) is a local Indonesian fish that is widely consumed and has the potential to become ornamental fish. This fish must be domesticated to suppress its exploitation from natural catches. The domestication process requires biological information including eating habits. For this reason, in this study, the identification of phytoplankton contained in the stomach contents of the agile fish was carried out. Fish samples were obtained from Rawa Metukul, South Bangka Regency. The types of phytoplankton in the stomach and intestines of lively fish are the classes Bacillariophyceae, Chlorophyceae, Cyanophyceae, Chlorophyceae, Chrysophyceae, Chrysophyceae. The most dominant species were found in the Chlorophyceae class with an Index of preponderance value of 42.42%, while the Chrystophyceae class was found at least 2.99%.

Abstract

Grouper production in Indonesia can be supported by hybridization technology which can produce grouper species with relatively faster growth and more resistance to disease. Cantang grouper is a type of grouper fish that was engineered by crossbreeding between female tiger grouper (Epinephelus fuscoguttatus) and male grouper Kertang (Epinephelus lanceolatus). The purpose of this study was to determine the stages and technology of nursery grouper Cantang which was carried out at BPBAP Situbondo. The method used in this research is the method of observation, participation, and interviews. The primary data needed in this study are data on infrastructure, data on the number and size of seeds, feed management, water quality management, and harvesting. The data is presented with a descriptive method by discussing the data that has been obtained compared to the theories that have developed at this time. The results of this study indicate that cantang grouper nursery activities start from tank preparation, water filling, seed selection and distribution, feed management, water quality, fish pest and disease control, grading, and harvesting of cantang grouper seeds. During the practice period, the seeds were spread from hatcheries with a stocking density of 3000 to 5000 individuals in one tank with a size of 4 x 2.5 x 1 m, or the equivalent of 300 to 500 individuals/m3. The distribution of seeds is carried out after the acclimatization process, namely the adaptation process before releasing the seeds. After the seeds are removed, the tub is given an antiseptic to prevent disease in the seeds. There are several factors that can affect the growth rate of seeds, namely water quality management and feeding. During the maintenance period, a flowing water system is used, so that the water used is continuously renewed. In the morning, the seeds are flushed and soaked using fresh water, with the aim of releasing mucus on the seeds so as to reduce the potential for disease outbreaks. Nursery grouper at BPBAP Situbondo can run optimally by paying attention to the stages of cultivation, especially in the feed management and water quality management.

Abstract

Blue swimming crab is a fishery product with high economic value in Indonesia. Betahwalang Village, Demak, is one of the crab fisheries locations in the province of Central Java. High selling prices and processing industry demand encourages fishing activities. One issue brought on by increased fishing activity is the smaller crab size. It will impact the crab fishing industry in Betahwalang. The majority of the fisherman in Betahwalang Village catch crabs using arad nets, simple gill nets, and traps. This study aims to evaluate the size of crab catch results on fishing gear used by fishermen and recommend proper fishing gear for catching crabs. This research was conducted in April 2019. The catch size of crab was the primary data collected for this study, also with data on fishing grounds, methods, and characteristics of fishing gear. Data were collected by observation, interviews, and measurements of fishing gear and the carapace width of the crab. The results of data collection and processing were analyzed descriptively. The results showed that the highest proportion of legal size crabs (carapace width ≥10 cm) was caught in traps, while the proportion of unlegal size crabs caught was mostly in bottom gillnets and mini trawl.

Abstract

Barbodes sellifer merupakan merupakan ikan air tawar dari keluarga cyprinid. Spesies ini pertama kali dideskripsikan pada tahun 2021 oleh Kottelat dan Lim. Saat ini spesies Barbodes sellifer dapat ditemukan di Singapore dan malaysia. Di Indonesia sendiri barbodes sellifer ditemukan di Sumatera, Kepulauan Riau hingga pulau Natuna. Kehadiran Barbodes sellifer di Kepulauan Bangka merupakan catatan baru. Meskipun spesies ini dapat ditemukan di Pulau Bangka, namun jumlahnya tidak banyak, sehingga perlu dilakukan upaya-upaya domestifikasi untuk mempertahankan populasi. Agar kegiatan domestifikasi dapat berjalan dengan baik, perlu melakukan beberapa penelitian mendasar yang salah satunya adalah studi morfometrik dan meristik untuk memastikan validasi spesies dan sebagai dasar untuk penelitian-penelitian selanjutnya. Dalam penelitian ini kami melakukan analisis karakter morfometrik dan meristik spesies Barbodes sellifer yang ditemukan di Pulau Bangka dan sebagai langkah awal dalam proses domestikasi. Hasil studi karakter morfometrik menujukan panjang total (TL) 7,4 cm, panjang standar (SL) 6,0 cm, tinggi kepala (HD) 1,0 cm, diameter mata (ED) 0,5 cm, tinggi badan (BD) 2,0 cm, panjang sirip ekor bagian atas (LUCL) 1,2 cm, panjang sirip ekor bagian tengah (LMCL) 0,8 cm, panjang sirip ekor bagian bawah (LCLL) 1,6 cm. Sedangkan meristik spesies Barbodes sellifer yaitu jari-jari sirip punggung memiliki rumus D.I-II.7, jari-jari sirip anal memiliki rumus A.6, Jari-jari sirip dada memiliki rumus P.I-II.10, Jari-jari sirip perut memiliki rumus V.I.7. Ikan barbodes sellifer memiliki tipe mulut terminal,bentuk tubuh compressed, tipe sisik ctenoid dan bentuk ekor forked.
