Abstract

One of the industrial activities that produces a lot of liquid waste is the tofu industry. Most of the liquid waste from industry flows directly into the sewer without prior treatment. This research aimed to determine the best plant biomass for reducing contaminants in tofu liquid waste. This research used an experimental method with a completely randomized design with 4 treatments and 3 replications, namely A (without addition of Azolla), B (addition of Azolla 250 grams), C (addition of Azolla 3000 grams), and D (addition of Azolla 350 grams). Tofu waste samples were obtained from the Cheese Tofu Factory located in the Cibuntu Tofu Industrial Center, Bandung City. The results of research for 15 days showed that the addition of Azolla microphylla could reduce the levels of contaminants in tofu liquid waste. The addition of 300 grams of Azolla microphylla plants to the phytoremediation process provided the best reduction in contaminants in tofu liquid waste by reducing BOD concentrations by 61%, nitrate by 77.49%, and phosphate by 68.44%.Keywords: Azolla microphylla, phytoremediation, tofu industry.

Abstract

Central Sulawesi has a diverse diversity of ichthyofauna. Gobies are one type of fish abundant in fresh water and can be found from the upstream to the downstream of the river. The abundance and information on the types of gobies are still limited in several rivers in Central Sulawesi. Tolitoli Regency is one of the areas that still has minimal information on the diversity of gobies, so it is necessary to research collecting gobies in the watershed in Tolitoli Regency. The research was conducted from July 2020 to December 2020 in the watershed of Baolan District (Dadakitan Village, Buntuna Village, and Tambun Village), Tolitoli, Central Sulawesi. The sampling locations in the watershed are divided into 3 parts, namely the upstream, middle, and downstream. Gobies were collected using the pore sampling method by preparing eight observation stations. Specimens were collected using nets (size 20 x 20 cm) with the method of catching against the current. The caught fish were kept in a mini aquarium and then documented using a digital camera. Furthermore, the fish were preserved using 70% alcohol for identification. The results of the study showed that the collection of goby fish in the Tolitoli watershed, Central Sulawesi, was found to be 408 individuals consisting of 4 families (Butidae, Eleotridae, Gobiidae, Oxudercidae), 12 genera (Butis, Oxyeleotris, Belobranchus, Eleotris, Giuris, Redigobius, Awaous, Lentipes, Stiphodon, Sicyopus, Sicyopterus), and 16 species (Butis sp., Redigobius sp., Sicyopterus sp., Stiphodon semoni, Stiphodon sp., Awaous sp., Belobranchus sp., Schismatogobius sp.1, Schismatogobius sp.2, Eleotris fusca, Oxyeleotris sp., Giuris sp., Sicyopus zosterophorus, Sicyopus sp.1, Sicyopus sp.2, Lentipes sp.). The highest abundance of goby fish species in the Tolitoli Watershed is Stiphodon semoni (47,79%).  Keywords: Amphidromus, sustainability, aquatic organisms.

Abstract

The northern coast of Bali possesses significant natural resource potential, particularly in Desa Musi, Kecamatan Gerokgak, which serves as a site for fish and seaweed cultivation managed by the local communities. However, some of these aquaculture activities lack adequate wastewater management systems. This study aimed to evaluate the water quality along the coast of Desa Musi, Kecamatan Gerokgak, Bali. A quantitative descriptive approach was employed, with purposive sampling conducted at selected locations along the coastal area. The water quality parameters assessed included salinity, pH, temperature, phosphate, ammonia, lead, and cadmium concentrations. The findings revealed that the coastal waters of Desa Musi generally support marine biota. However, the concentrations of lead and cadmium exceed the threshold values stipulated by Kep-51/MenKLH/2004. These results underscore the need for regular water quality management and monitoring to ensure environmental sustainability and support the livelihoods of the local community.Keywords: Coastal ecosystems, environmental monitoring, heavy metals.

Abstract

Floodplains are dynamic freshwater ecosystems characterized by significant ecological shifts between dry and rainy seasons. The snakeskin gourami (Trichopodus pectoralis), a resilient blackfish species, thrives in these extreme environments due to its specialized labyrinth breathing organ. However, its wild populations are declining, necessitating sustainable conservation strategies. This study evaluated the effectiveness of the special area for conservation and fish refugia (SPEECTRA) model, developed by BRPPUPP, in Patra Tani, Palembang. The SPEECTRA model leverages seasonal fish migration from rivers to floodplains during inundation, capturing fish in designated conservation ponds to facilitate spawning, protection, and production enhancement. Over a 30-day period at the Patra Tani Installation, purposive sampling was employed to collect T. pectoralis specimens. Growth patterns were analyzed using length-weight regression, and Fulton’s condition factor (Kn) was calculated. Results demonstrated that W=0.0108 L3.1076 with R2=0.9469. The growth pattern of the studied fish exhibited positive allometric characteristics, indicating that the population is likely in a favorable condition. This finding indicated the effectiveness of SPEECTRA as a fishery sanctuary, safeguarding key species such as T. pectoralis while mitigating anthropogenic pressures on aquatic ecosystems.Keywords: Aquatic organisms, sustainability, condition factor.

Abstract

The Mentawai Tsunami, October 25th, 2010, was caused by collision between the Indian-Australian plate with the Eurasian plate that caused the fault in the Sunda subduction zone megathrust. Tsunami with magnitude 7.7 MW occurred at 21:42:22 pm which epicenter at 3.484oSL and 100.114oEL, 20.6 km depth in the Indian Ocean, 110 km from the North Pagai. Tsunami Mentawai, 2010 is started by an underwater earthquake and called as slow tsunami because the ground shaking is quite weak in long periods but produce great waves. Mentawai tsunami cesarean parameters are strike 325o, dip 11.62o and slip 101.4625o. This research aims to know the lesson learned of The Mentawai Tsunami. The impact is coastal degradation, i.e. loss of small islands, abrasion and mangrove degradation. The lessons learned are people should be aware of natural sign of tsunami, evacuate themselves to high places, avoid the inundation area, take the best decision based on situation. Tsunami mitigation must be implemented to save lives and minimize risks.Keywords: Mentawai Tsunami, tsunami impact, lesson learned.

Abstract

This research was carried out to determine the effect of probiotic feed on the growth of catfish (Clarias sp.) in two different culture systems. This research was carried out for 30 days using a randomized block design method, namely K (conventional group) and B (biofloc group), each with 3 replications. The data studied were catfish growth, survival, feed conver-sion and feed efficiency. Data collection was carried out 3 times, namely at the beginning, middle and end of the research. Growth and survival data were tested using the non-parametric Mann-Whitney U-test. The results showed that there were differences in catfish growth (P<0.05) in conventional and biofloc culture systems. The con-ventional group produced an average absolute weight of 5.9 grams and the biofloc group produced 6.3 grams. The absolute length of catfish in the conventional group averaged 10.1 cm and in the biofloc group it was 11.1 cm. Catfish survival data showed there was a significant difference (P<0.05). The survival value in the conventional group was 83%, while in the biofloc group it was 93.3%. The FCR value in the conventional group was 1.4 and in the biofloc group was 1.3. Catfish in the conventional group got a feed efficiency of 49% and in the biofloc group it was 51%.Keywords: Biofloc, Catfish, Conven-tional.

Abstract

The characteristics of the sponge structure, homogenous, flexible, and simple, but pervaded by canals and their ability for filter-feeding, may facilitate development of intimate associations with other organisms. This study reviewed the described symbiotic associations between marine sponges and other organisms as well as among marine sponge species. Associations in marine sponges show a wide range of relationships with their symbionts. These can range from mutually beneficial, to commensal, to parasitic or pathogenic. Sponge species also vary in the types of symbionts they host from facultative sponge associates that also live in other sheltered habitats, to obligate sponge associates that occupy a variety of sponge species, to obligate specialists on particular sponge species. The associations can cause the morphological alteration of the symbionts and other adaptive behaviour. Observations of new and unique associations were also discussed.

Abstract

Pangasius is a freshwater fish included in the main commodity by the Ministry of Marine Affairs and Fisheries, Indonesia. Siamese catfish production ranked 4th in freshwater fish commodities in 2016 after goldfish, tilapia, and catfish. Pangasius has a lack of EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) if compared with fish from the sea. Application of additional different levels of soybean oil in commercial fish fed to enhance EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Perkasa pangasiid flesh. This study was conducted to determine the effect of adding soybean oil with different levels of commercial fish feed given to Perkasa striped catfish on growth performance, feed efficiency, EPA (Eicosapentaenoic acid), and DHA (Docosahexaenoic acid). This experimental study used a Complete Randomized Design (CDR) with triplicates and five treatments with additional levels of soybean oil in commercial fish fed: (a) 0%, (b) 2%, (c) 4%, (d) 6%, and (e) 8%. The result showed that treatment of (e) is the best treatment for increasing the EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Pangasius flesh. However, additional different levels of soybean oil in the commercial fish feed have no negative effect on growth performance and feed efficiency in Perkasa pangasiid.

Abstract

Kappaphycus alvarezii seaweed is important for the processing industry because it contains carrageenan used as a stabilizer, thickener, material forming an emulsifier. This study aimed to find the best and optimal initial seed weight treatment for maximum biomass production, growth rate, and carrageenan content. The research location was in the waters of Aeng Batu-Batu Village, Takalar Regency, South Sulawesi in August-September 2022. The randomized block design method (RAK) consisted of 4 treatments each with 4 repetitions. Seaweed seedlings from spores were weight of 20 g, 40 g, 60 g, and 80 g planted at 60 cm depth respectively and maintained for 45 days. Data analysis used (ANOVA) and W-Tuckey to determine the differences between treatments. The result of the analysis of variences showed that the weight of 40 g, 60 g, and 80 g had an effect on the biomass production, growth rate, and K. alvarezii carrageenan content. However, the highest yield was obtained at a weight of 20 g which had a very significant effect (p<0.01).

Abstract

The purpose of this study was to determine the optimum level of addition of chitosan and probiotics in feed to increase the growth rate and daily feed consumption of giant gouramy  (Osphronemus gouramy). The method used in this research is an experimental method of completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without giving chitosan and probiotics (control), (B) giving chitosan at 7.5 g/kg feed and probiotics at 10 ml/kg feed, (C) giving chitosan at 7.5 g /kg feed and probiotics at 15 ml/kg feed, (D) chitosan at 7.5 g/kg feed and probiotics at 20 ml/kg feed, (E) chitosan at 7.5 g/kg feed and probiotics of 25 ml/kg feed. The parameters measured were absolute length absolute weight, specific growth rate, feed utilization efficiency ratio (EPP), survival rate, and water quality. Data were analyzed using the Anova test at the 5% level. The results showed that the addition of different concentrations of chitosan and probiotics to commercial feeds could affect growth, and EPP but did not affect the survival rate of giant gouramy. The results obtained during the study showed that treatment C with the addition of chitosan of 7.5 g/kg of feed and probiotics of 15 ml/kg of feed resulted in the highest absolute length growth of 4.87 cm, the highest absolute weight growth of 19,35 g, the highest daily growth rate was 46,08%, the feed efficiency was 91,5% and survival rate was 97,78%. Whereas in terms of the effectiveness of treatment B with the addition of chitosan 7.5 g/kg of feed and less probiotics, namely as much as 10 ml/kg of feed, the treatment was as good as treatment C.
