Effect Of Non Dental Glass Fiber Orientation On Transverse Strength Of Dental Fiber Reinforced Composite

FRC is widely used in dentistry especially for dental bridges construction. E glass fiber is commonly used because it has good properties and good bonding with polymers. Its availability is limited and its price quite expensive in Indonesia. Non dental glass fiber is available in Indonesia with lower price. The aim of this research was to evaluate the effect of non dental glass fiber orientation on transverse strength of dental FRC. Non dental glass fiber (HJ, China) with two orientations (Roving and Woven roving), Flowable composite (CharmFil Flow, DenKist, Korea) , Silane coupling agent (Monobond S, Ivoclar Vivadent, Liechtenstein) and distilled water. 24 specimens of non dental glass FRC, divided into 2 groups. The specimens was immersed in water for 24 hours and 7 days. The data were analyzed by Independent sample T-test. T-test analysis showed that for transverse strength with 24 hours water immersion there was a significant difference between the two orientation groups (p 0.05). In conclusion: there was different transverse strength between roving and woven roving orientation in dental FRC

Model Pertumbuhan Logistik Dengan Waktu Tunda

The logistic growth model with time delay has developed from the classical logistic model, where as in the growth logistic model with time delay, the growth process delay from a population is calculated. This delay cause population decrease then increase so oscillation appears in population growth. So, the solution is not a monotonous function. The result of analysis indicate that the logistic growth model with time delay have two equilibrium points. Each equilibrium points is analyzed for their stability based on time delay variation on the population growth. The longer time delay in the population growth can cause the unstable growth, hence the population decrease and become extinct

The Application of Integrated Multi Trophic Aquaculture (IMTA) Using Stratified Double Net Rounded Cage (SDFNC) for Aquaculture Sustainability

The increase of fishery production nationally and Internationally may impact on the potential emergence of a variety of environmental problems. The application of sustainable aquaculture is urgently needed by breeding fish for commercial purposes in a manner such that it has a minimum impact on the environment, contributing to the development of local communities and generating economic benefits. The design of the cage and farming practice in aquaculture activities are the important steps to ensure that farming activity is still observed in order to anticipate the risk of organic enrichment caused by the activities. The application of Integrated Multi-Trophic Aquaculture (IMTA) on the Stratified Double Floating Net Cage (SDFNC) integrated with biomonitoring are an appropriate solution to the ongoing productive farming practices. IMTA is an aquaculture practice using more than one species of biotas which have ecologically mutual relationship as a part of the food chain in the area at the same time. The application of IMTA allows farmers to get several aquaculture products in the same area without increasing the horizontal area of the farms. At first, the SDFNC has been applied for farming Cyprinus carpio and Tilapia niloticus as polyculture system in freshwater ecosystem of Rawapening Lake, Central Java. Its operation has been able to increase the production capacity of at least 75% of conventional cages. The application of SDFNC-IMTA using milkfish (Chanos Chanos), seaweed (Kappaphycus alvarezii), and white shrimp (Litopenaeus vannamei) has been able to minimize the impact and maintain the water ecosystem in the Gulf Awerange, South Sulawesi
