Abstract

Long-tailed macaques (Macaca fascicularis) live in groups with a social structure consisting of many males and females (multi-male and multi-female), and interactions between individuals such as social activities are strongly influenced by hierarchy. This study aimed to determine the social hierarchy structure of adult male long-tailed macaques (M. fascicularis) and their behavioral profiles in middle area groups in the Pura Agung Pulaki, Bali. Observations were conducted using focal animal sampling and ad libitum sampling methods. The hierarchical structure was observed using three methods, namely the sociometric matrix method, food distribution, and other analyses that support hierarchical determination (non-copulatory mounting, scrotal touching, and combing between males). The highest activities in the middle area group were browsing (17.2%) and moving (17.2%). The hierarchical structure in the middle area group is ordered from the most dominant individual as follows: Ra, Co, Ma, Ku, Cha, Fra, Ka, Ni, In, and Jo. The hierarchical structure in the middle area group is linear. The provision of food bait has been proven effective in determining the social hierarchy structure in long-tailed macaques (M. fascicularis). This study can be used as a basis for the conservation of long-tailed macaques (M. fascicularis) in the Pura Agung Pulaki area.

Abstract

Aeromonas hydrophila, commonly found in aquatic environments, is a Gram-negative bacterium frequently pathogenic to fish, causing diseases such as hemorrhagic septicemia or Motile Aeromonas Septicemia (MAS) in various freshwater fish species. This study investigated the antibacterial potential of red onion skin extract (Allium cepa L.) extracted using 99% absolute alcohol against the growth of Aeromonas hydrophila. The experiments were conducted with varying extract concentrations of 5%, 10%, 15%, 20%, and 25%, using tetracycline as a control. The results demonstrated that the red onion skin extract was able to inhibit the growth of Aeromonas hydrophila, as indicated by the formation of inhibition zones around the growth media. The average diameters of the inhibition zones produced by the extract at concentrations of 5%, 10%, 15%, 20%, and 25% were 1.21 mm, 2.43 mm, 3.36 mm, 5.70 mm, and 6.23 mm, respectively. Statistical analysis using a One-way ANOVA test with SPSS software showed a p-value of 0.000, indicating a significant difference among the red onion skin extract concentrations. Therefore, a Least Significant Difference (LSD) post-hoc test was performed to identify specific differences between the concentration treatments

Abstract

This study aims to analyze the effect doses of Bacillus sp. Probiotics on the survival rate of white snapper (Lates calcarifer) larvae.  The research was conducted at the Gondol Research Institute for Mariculture, Bali, over a 20-day period using a Completely Randomized Design (CRD) with three treatments and three replications: P0 (control, without probiotics), P1 (3 mg/L), and P2 (5 mg/L). Observed parameters included water quality (nitrate, nitrite, ammonia, phosphate, temperature, pH, salinity, DO), total bacterial count (TBC), survival rate (SR), larval length, and hatching rate (HR). The results showed that the administration of Bacillus sp. probiotics had a significant effect on the survival rate of white snapper larvae (p < 0.05). Based on ANOVA, there were significant differences in SR between treatments. The Bonferroni post hoc test revealed that treatment P2 (5 mg/L) was significantly different from both the control (P0) and P1 (3 mg/L), with P2 producing the highest average SR of 84%, compared to P1 at 70.3% and the control at 50.3%. Meanwhile, probiotic administration did not have a significant effect (p > 0.05) on water quality parameters or larval length. The highest larval length was also recorded in treatment P2, with an average of 1.5 cm on day 20. The use of probiotics contributed to the reduction of toxic compounds such as nitrate, nitrite, and ammonia, and helped stabilize the rearing water environment. Based on these results, it can be concluded that the administration of Bacillus sp. probiotics at a dose of 5 mg/L is the optimal dosage for improving the survival rate of white snapper larvae and maintaining the quality of the aquaculture environment.

Abstract

The black ghost fish (Apteronotus albifrons) is a freshwater ornamental fish with a distinctive knife-like shape (Knife fish). Its unique shape makes it have high economic value in the market. However, the growth rate and high mortality of this fish are obstacles for cultivators. The main focus of this study was to determine the effect of providing different types of feed on the growth and survival of black ghost fish (A. albifrons) seeds. The study was conducted at the Mina Mustika Fish Farming Group, Bekasi City, for 45 days using a Completely Randomized Design (CRD). The treatment consisted of three types of feed, namely natural feed (Tubifex sp.) (P1), a combination of natural feed (Tubifex sp.) + commercial feed (PF100) (P2), and commercial feed (PF100) (P3), with three replications in each treatment. The parameters observed were absolute length growth, absolute weight, specific growth rate (SGR), and survival rate (SR). The measurement of water quality parameters was carried out as a form of attention to supporting factors for the study. The findings showed that the combination feed treatment (P2) provided the highest growth in length, weight, and specific growth rate with absolute length values ​​(4.36 cm), absolute weight (3.73 gr), and SGR (4.67%), followed by natural feed (P1) providing absolute length (4.09 cm), absolute weight (3.39 gr), and SGR (4.54%), and the lowest commercial feed (P3) providing absolute length (3.37 cm), absolute weight (2.50 gr), and SGR (3.91%). The highest survival rate (SR) was found in the natural feed treatment at 94%, followed by commercial feed at 93%, and combination feed at 91%. In general, water quality during the research period was in the optimal range to support the growth and survival of black ghost fish (A. albifrons) seeds.
