Abstract

Zoos have four main roles namely conservation, research, education and recreation. Whether the existence of the zoo has succeeded in increasing or at least influencing people's perceptions of animal conservation should be investigated further. The research aimed to assess the image of the zoos and perception of the visitors about orangutan conservation. This study applied the questionnaire and methods to Indonesia zoo's, and examines the effect of the zoo at changing visitor's conservation awareness. The result showed that there were no significant difference acros the sites and between arrival dan departures. This could be caused by many reasons, for example the short visit time, minimal information obtained during the visit or the background of the visitors themselves.

Abstract

The ecological impacts of tin mining activities in the Bangka island is the presence of heavy metal contamination that accumulated in the environment. One of the heavy metals that was often found in post-tin mining areas is lead (Pb). Mycoremediation is a method that can be used to reduce lead pollution in post-tin mining areas. This study aimedto isolate, resistance test and identify to Pb-resistant soil fungi (rhizosphere) in the post-tin area of Bangka. The research methods included isolation, test of fungal resistance to Pb metal (Control, 150ppm, 250ppm, 350ppm, 500ppm, 1,000ppm, 5,000ppm and 10,000ppm), macroscopic and microscopic identification. The results showed that 9 isolates tested, there were 6 isolates that were resistant to Pb up to the concentration of 5,000 ppm, namely isolates I1(Rhizoctonia), I2(Penicilllium sp1), I5(Papulaspora), I6(Penicillium sp2), I7(Penicillium sp3) and I9 (Sclerotium). Three isolates of soil fungus were not resistant to Pb up to a concentration of 5,000 ppm, namely isolates I4 (Sclerotium), I8(Microsporum), and I10(Cladosporium). All isolates did not grow anymore at a concentration of 10,000 ppm of Pb.

Abstract

Bycatch small pelagic fish during the fishing season can be oversupplied so that its price goes down.  The study aims to analyze the proximate of local fish powder from the by-catch and probiotics of Probio_FM in the fish feed in Bangka Belitung. The method was the data compared with the Indonesian National Standard, SNI 01-2715-1996/Rev: 92 about the raw material of animal feed as fish powder and fish feed with six different treatments. The study found that the bycatch or trash from small pelagic fish could be used as a fish powder or fish feed. The proximate analysis on fish powder and fish feed with probiotics Probio_FM included as the quality of SNI. Crude protein values from 25.75% until 66.96% that was above SNI standard I (1.5%), II (2.5%), and III (3.0%) could be followed up into an economical business. Fermented activity from Probio_FM could degrade the protein and other components proximate such as ash content, crude protein, crude fat, crude fiber, calcium, Phosphor, and NaCl. The amino acids from protein were getting simpler and easier being absorbed by fish in culture or livestock farms. Probio_FM was assumed to degrade the protein value and other components proximate due to the utilization of nitrogen and ammonia derived from the process fish protein hydrolyzation of probiotic bacteria. The production of local feed should be implemented to reach feed security and very important to be developed into a community business. Proximate analysis of bycatch could support sustainable good aquaculture practices in the future.

Abstract

Offshore tin mining can causes heavy metal contamination, one of which is lead (Pb) metal. Lead pollution can causes environmental damage and  toxic  to living organisms. One of the methods to reduce lead pollution was by bioremediation techniques. Resistant bacteria were potential to be used as bioremediation agent. This research aimed to determine the lead level in Sampur coastal waters and to obtain bacteria that have resistance to lead (Pb). The research method was purposive sampling to take a sample of water and sediment. The AAS test results indicated that the Pb level in seawater is higher than sediment. A normal sea water pH can caused the Pb solubility in the water to be stable. The Pb level in seawater was passed the established quality standards, so that potentially cause toxicity for the aquatic biota. The highest Pb levels in sediment was found in vicinity of tin mining activities area. The isolation results showed that the number of bacteria ranged from 11,105 – 34,105 CFU/g. The higher Pb levels in sediment causing the number of bacteria will be lower. There were 7 isolates that resistant of Pb 100 ppm and constitute bacteria from the genus Alcaligens, Meniscus, Neisseria, Erythrobacter, and Alteromonas.

Abstract

Traditional herbal medicines are now attracted significant attention used as the basis for modern medicines, including the plant of rukam (Flacourtia rukam) from the Flacourtiaceae family which is known by the public as medicine. This research aimed to explore the potential antibacterial activity for the plant of rukam (F.rukam) against bacterial Staphylococcus aureus and Escherichia coli. This research method was to first test the secondary metabolite content of F. rukam by using four solvents. The antibacterial activity extract from leaves of F. rukam was examined against S. aureus and E. coli. The antibacterial activity was assessed in the concentration include 20%, 40%, 60%, 80%, and 100% by disc diffusion method. Phytochemical test results such as phenolics, flavonoids, saponins, steroids, and alkaloids are secondary metabolites of the F. rukam plant. The highest zone of inhibition is at a concentration of 60% using methanol solvent, which is an average of 8.95 ± 1.84 in S. aures isolates, while the E. coli bacterial isolates have an average of 9.03 ± 0.95 . This result was different from using ethanol solvent where the highest inhibition zone was at a concentration of 20%, respectively 7.73 ± 2.79 in S. aureus isolates and 6.61 ± 2.18 in E. coli bacteria isolates. Antibacterial efficacy shown by this plant F. rukam provides a scientific basis and thus validates traditional use.

Abstract

Seven Salmonella lytic phages found in water sample of river near UBB campus building. Phages were characterized by plaque morphology (plaque diameter size and shape) and phage host range. Phages formed plaques with diameter size ranges from 1.06 mm to 4.90 mm, and form shape such as small dot, circle, elongated, or irregular. Factors effect plaque forming by phages are phage titer number and incubation time. All phage isolates have broad host range include Gram negative and positive. Six phage isolates are able to lyse Salmonella, Staphylococcus aureus, and Escherichia coli, meanwhile one phage isolate is able to lyse Salmonella and Staphylococcus aureus.

Abstract

Fungus is one of the main biotics component in ecosystem, included forest. The played a significant role in organic material decomposition. The present study aimed to obtained the presence of macroscopic fungus in TWA Permisan. We explored the presence of macroscopic fungus using exploration method. We found 23 species of macroscopic fungus divided into two Phylla i.e. Basidiomycota and Ascomycota. There were 13 species of macroscopic fungi which were live in dead wood and 10 species live on the ground and litter. Data on fungus biodiversity is very usefull for management and conservation effort of forest resources.

Abstract

Litopenaeus vannamei is one of the most common shrimp species cultivated with the semi-intensive system in Indonesia. This system required large food and probiotic input during cultivation and certainly will impact the water quality and the presence of the microbial colony. The unhealthy water circulation will increase microbe pathogen. Fungi is one of ubiquitous microbe that often appears in shrimp pond. The aim of this study is to identify and calculate the biology index from shrimp cultivation ponds. This research was implemented in March 2019 – April 2020. The method of this research is purposive sampling to get the fungi culture from inlet, outlet and rejuvenate shrimp ponds. The identification of fungi was done with macroscopic and microscopic examination. The result found 9 isolates fungi comprised of 8 species. There were 4 fungi identified from the inlet shrimp pond, Aspergillus sp 1, Aspergillus sp 4, Penicillium sp, and Trichoderma sp 2, while from outlet pond were Aspergillus sp 1, Trichoderma sp 1 and from rejuvenating shrimp ponds were Saccharomyces cerevisiae, Trichoderma sp 1 and Penicillium sp. There were no fungi found from L. vannamei, because all of the L. vannamei shrimp in healthful condition.
