“…Pemeliharaan kepiting bakau secara indoor dengan kegelapan total dapat mengurangi kandungan karotenoid dan protein ovarium, sehingga kondisi tersebut menjadi faktor pembatas proses reproduksi (Farhadi et al 2021). Tangki pemeliharaan induk yang digunakan berwarna hitam, warna ini cocok juga untuk pemeliharaan larva kepiting bakau stadia instar crablet (Rabbani & Zeng 2005, Thien et al 2022. Tangki dilengkapi dengan sistem pengairan flow through dan aerasi, seperti yang dideskripsikan oleh Mann et al (1999).…”

This activity aims to provide knowledge, insight, and skills in the application of recirculated aquaculture system (RAS) technology and phytobiotics to members of the Bahari Sakti mud crab hatchery group on Penyengat Island, Tanjungpinang, Riau Islands. Mastery of this application is important to improve the production performance of the mud crab hatchery group which is faced with the problem of high frequency of disease attacks on broodstock and low survival rate of larvae. The activity, which includes training, piloting, and mentoring, were take place from June‒September 2022, attended by 20 participants consisting of members of the Bahari Sakti mud crab hatchery group and public. The training materials covered the technical and management aspects of mud crab hatchery, RAS application, and phytobiotics of garlic flour in broodstock and larvae rearing. Pilot methods and mentoring were conducted in the form of RAS installations and application of phytobiotics with participants. After attending the training, there was a significant increase in knowledge and insight of these three aspects by 47, 51, and 26%, respectively, for the mud crab hatchery, phytobiotic, and RAS aspects. Pilots and mentoring in the form of rearing and spawning in the RAS system with the application of phytobiotics were carried out after training at the production facility of mud crab hatchery group. Participants in the pilot and mentoring activities were quite enthusiastic, although the attendance rate of participants was only 25‒35%. The RAS application can improve the water quality of the mud crab broodstock rearing media, while for the application of phytobiotics was not evaluated.

“…The use of shelters and density restrictions have been tried to reduce cannibalism in crabs (Yin Thien et al, 2022) however, cannibalism has not been completely abolished. Utilizing fresh feed, such as trash fish, mollusks, and squid meat for growth and to cope with cannibalism has been practiced with good results, however, facing an issue with their availability (seasonal), storage, and nutrient leaching.…”

Amphipoda is a benthic fauna occupying aquatic environments that can be used as a live feed for mud crabs. The abundance of amphipods in the water is thought to impact the preying capacity of crablets, which in turn will affect their growth performance. This study aims to determine the preying capacity of the crablet stage of Scylla tranquebarica exposed at different densities (20, 30, and 40 amphipods / 0.5 L) of amphipod, Grandidierella megnae. The preying capacity was estimated by counting the number of amphipods ingested by an individual crablet during the 60-day rearing period. The main parameters measured were daily consumption rate (DCR), Cumulative molting (CM), Feed conversion ratio (FCR), and the specific growth rate of weight (SGR-W). The results showed that the DCR and FCR were not affected by amphipod densities but the higher the amphipod density the higher the SGR-W and CM. Based on this study, 30 amphipods / 0.5 L is recommended as the optimal density to optimize the DCR and improve the growth performance of crablets. It is also proposed that surplus live feed will potentially reduce the cannibalism rate of crablets during weaning. However, more research needs to be carried out to elucidate the benefits of crablet-feeding amphipods in communal systems.

“…Also, an experimental study of the dynamics of fresh-salt water in sand reservoirs has been developed [10] . In 2022, Thien et al have studied the effects of reservoir color with sand and shelter [11] . Moreover, for the foundation of the reservoir with the hot sand, an experimental analysis of the characteristics (solidification and migration) of the solar salt is applied [12] .…”

<p>In porous media, the thermal transfer phenomenon is widely applied in diverse energy-intensive industrial processes. This research paper aims to elucidate the simultaneous transfer of mass and heat within a ceramic porous tank. To simulate these transport phenomena, a numerical method is developed: Control Volume Finite Element Method (CVFEM), in conjunction with the utilization of a free mesh generator called Gmsh. The study showcases numerous simulation results that depict the transport phenomenon, such as the three-dimensional evolution of three parameters (temperature, saturation and pressure) during the heating of the ceramic tank. By employing this numerical model, a more comprehensive comprehension of these transport phenomena can be achieved.</p>
