Abstract. Nurhalisa N, Nur I, Suryani S. 2022. Potential extracts of wedge sea hare (Dolabella auricularia) as immunostimulators in comet fish (Carassius auratus auratus) infected by Aeromonas hydrophila. Biodiversitas 23: 1884-1893. Microencapsulation is an innovative method to protect the active compound of pharmaceutical material from environmental impacts or unwanted conditions. This study aims to determine the active compound content and appropriate concentration of wedge sea hare extract (Dolabella auricularia) using the microencapsulation method to treat Aeromonas hydrophila bacterial which infected in comet fish (Carassius auratus auratus). The treatment consisted of three concentrations of D. auricularia extract (6.3, 7 and 7.7 g/kg feed) and commercial feed as a positive control in triplicates. C. a. auratus fed with experimental diets twice a day (8.00 a.m and 4.00 p.m) for 30 days of culture period before being challenged with an injection of A. hydrophila. Blood profile, weight gain, survival and relative survival of C. a. auratus were observed before and after the challenge test. The characteristics and types of active compounds in the extract were observed qualitatively, as well as the morphology and particle size distribution of the microcapsules. The results showed that D. auricularia extract contained phenol, tannins, steroids, terpenoids, alkaloids, and saponins. The microcapsules in all treatments were a spherical shape. The average diameter was similar to all extract treatments. The addition of D. auricularia extract microcapsules in the feed produced significantly different results on the blood profile, weight gain and survival. The highest of total leukocytes, total erythrocytes, hematocrit and blood hemoglobin were obtained in addition to 7.7 g D. auricularia extract/kg of feed with respective values ??of 7.35±0.94×104 cell.mm-3, 2.83±0.03×106 cell.mm-3, 22.43±0.03% and 6.72±0.02 g.dL-1, respectively. The highest weight gain was found in fish-fed diets contained of 7.7 g of D. auricularia extract (3.37 g). The highest relative survival and survival were found in the treatment of 7 and 7.7 g extract/kg of feed, which was 100%. This study concluded that microencapsulated with D. auricularia extract at dose 7 g extract/kg of feed was the optimum dose for C. a. auratus infected with A. hydrophila.

“…One kind of gastropod that has yet been widely known for its potential in inhibiting bacterial growth is the wedge sea hare (Dolabella auricularia). It is usually found in shrimp ponds as a pest for shrimp culture (Sofian et al 2021). However, it has potential for biomedical and economic benefits.…”

“…The length of the coastline is 9,518 km; it is located in the Indo-Pacific region (Maulidia et al 2019). Indonesia's geographical condition places it as one of the megadiverse countries (Chasanah 2008;Von Rintelen et al 2017;Sofian et al 2021). The territorial waters of Indonesia have the uniqueness and abundant diversity of ornamental fish for 240 species of marine ornamental fish and 226 species of freshwater ornamental fish (Ramachandran 2002;Khoironi and Saskara 2017).…”

Abstract. Mulyati S, Herdianto T, Suhermanto A, Sofian A. 2022. The prospects of business development in ornamental fish in Southeast Sulawesi, Indonesia. Biodiversitas 23: 6413-6419. Ornamental fish is a potential commodity necessarily optimized to improve the welfare of society. One of the Indonesian provinces producing diverse species of ornamental fish to export is Southeast Sulawesi. This study aimed to evaluate the ornamental fish potentials and create an evaluation possibly implemented as a consideration to determine business development strategies. The method was a case study, collected data through observation, interviews, literature study, and internal and external conditions were analyzed using SWOT analysis. The study analyzed the potential, trade, and strategy for business development in ornamental fish in Southeast Sulawesi. The study discovers that 38 species are traded, and nine of them are dominantly traded. Moreover, there are six main species potentially cultivated due to the demand and stable production; they are Betok Kupang (Chrysietera cyanea), Capungan (Apogon sp.), Angel KKO (Cirrhilabrus sp.), Clown fish (Amphiprion ocellaris), Keling Rub (Cirrhilabrus sp.), and Letter six (Paracanthurus hepatus). The development of ornamental fish cultivation can be implemented with the S-O (strengths–opportunities) strategy that manages and protects the environment of ornamental fish, strengthens the capacity of fishers and stakeholders for environmentally friendly activities and export market orientation, and builds cooperation of fisherman, exporters, and stakeholders to develop business in ornamental fish by emphasizing local species with high economic values and market demands. These results can be a consideration in making decisions related to the development of ornamental fish.

This study aims to show what kind of problems and challenges occur in the middle of Papua Province development, as well as the extent of complexity of these development problems and the challenges of the New Autonomous Region to answer it. We use the systematic literature review method by showing a collection of literature from the Scopus database that discusses the development of Papua and analyzing the literature collection into several clusters. Bibliometric analysis is used to generate statistical models that show the relationship between each study. 151 literature sources were used in this study and produced three clusters namely development process, environment, and communication. From these aspects, several development efforts have been carried out by the government such as collaboration with the private sector, community capacity building through local value development, and the involvement of indigenous peoples. Moreover, there are several things that need to be considered such as land acquisition issues, the difficulty of access, planning and control functions, political intervention and interests, along with the communication system that has not been integrated. The New Autonomous Region can have a narrow span of control so it will optimize supervision and monitoring functions, but there are several things that need to be considered when implementing it such as planning, existing human resources capacity, and financial aspects. There are some limitations in this paper, where we cannot reach some highland areas to directly observe the challenges that occur there. Future research can develop discussions about Papua development through direct observations in those areas.
