EVALUASI COATING MATERIALS UNTUK MELINDUNGI BAKTERI PROBIOTIK PSEUDOALTEROMONAS PISCICIDA SELAMA PROSES MIKROENKAPSULASI DAN PENYIMPANAN

Disease is an obstacle in Pacific white shrimp culture that can cause economic losses. Probiotic bacteria Pseudalteromonas piscicida 1Ub RfR is able to improve the growth performance and immune responses of Pacific white shrimp and has the potential to be developed into dry products to make it more practical for use in the field. This study aims to obtain the best coating materials that can protect probiotic bacteria during the microencapsulation and storage process. This research was conducted in September-December 2020 at the Laboratory of Microbiology of IPB Sukabumi Campus and South-East Asia Food and Agricultural Science and Technology (SEAFAST). This research consists of 2 Chapters, Chapter 1 to obtain the best coating materials and Chapter 2 to obtain the best results after the microencapsulation process. Coating materials used in this study were whey protein and maltodextrin. The microencapsulation technique used is freeze drying and spray drying. The probiotic bacteria used was P. piscicida from Fish Health and Management Laboratory, Department of Aquaculture, FPIK IPB and was marked with rifampicin resistance (1Ub RfR). The research in Chapter 1 consisted of 4 treatments, including K (without coating material), A (single coating with whey protein), B (single coating with maltodextrin), and C (double coating with whey protein and maltodextrin). Furthermore, each treatment in Chapter 1 is continued for the microencapsulation process. The results showed that the treatment with double coating and encapsulated by freeze drying was the best probiotic products compared other treatments.

Modular greening technologies for buildings

In this research we provide the analysis of the modern green wall technologies. The modular greening technology for the buildings is universal invention with respect to the purpose of the building and it is applicable for greening buildings intended for any spheres of «going into nature» aims. The complexity of installation work of this modular constructive greening system is quite low, which is one of the main advantages of the invention. Due to the fact that the system can be installed both vertically and horizontally, a single coating system of modules is formed. These modules can optimally fill the facades of the building due to the fact that their dimensions can vary. The constructive weight of the system is not large; for this, the technological process is optimized. This system is the most environmentally and technically efficient for the green buildings.
