The purpose of this study is to conceptualize an urban Hi-Tech Cook-Stove (HTCS) design using agricultural waste. Several steps need to be carried out. First, determine the cooking activities depend on the family size and food categories. Second, calculate the energy required for cooking. Third, determine the mass of biomass fuel required. Fourth, calculate the fuel consumption rate. Fifth, design the dimensions of the stove by considering the ergonomics, easy in manufacturing, installation, etc. Sixth, estimate the volume of each component. The result shows that the fuel supply must adjust the flow rate of fuel, air to fuel ratio controlled by a simple mechanical-electric compressor, monitor the combustion chamber visually/automatically, and the dust must be collected/disposed of automatically/mechanically. HTCS must consider the pellets from the higher heating value and faster of biomass with a certain composition of chopped and fibre, also the safety and comfort, such as overheating control, air exhaust control, combustion control, cooling control. For the future, the HTCS technical design concept must be integrated with the electricity and hot water from solar energy by using a hybrid photovoltaic-thermal (PVT) collector and urban biogas digester in the development of smart grids and smart cities.
Fishing vessels used to catch resources from the sea has to pass some of the regulations from International Maritime Organization for sea-worthiness of the vessel especially about stability, resistance to acquire the highest velocity, and the vessel’s motion. This research discusses the effect of the vessel’s dimension and the hull shape by using the stability standard from IMO.The result shows that the ratio of the B/T which meets the stability criteria is 2.50 with the ratio of KG/H of the vessel is 0.65, with the assumption that the KG and H of the vessel are more than 0.70. Whereas if the resistance ratio B/T is big, the resistance for the vessel will be relatively smaller. In terms of the vessel motion, a vessel with a V-type hull will better than a U-type hull in seakeeping.
The development of information and technology has influenced many aspects of life including education. a lot of people start from students in the university and worker already speaking English fluently, but still there are some problem specifically for the students to speak English, university that have English English language programt is looking to find the solution. By hiring native English teacher or leacturer to improve their student’s motivation in English communication skill, the question is can the native English teacher gives the influence to the student. This research made to analyze how well the native English teacher can give the influence to the students especially in Darma Persada University for the students that are majoring in English Literature and in English Department. This research showed whether hired Native English teacher is a good idea or it isn’t. In this study, researcher used aquantitative approach to analyze the influence of native English lecturer in improving students motivation communication skill.. This research was conducted using the experimental method using pre-test and post-test control design.
This research mostly discusses the politeness strategies that is shown in Little Women movie. Politeness is a social behaviour to a speaker towards deferent wishes of the addressee in different concerns. The purpose of this study is to find the politeness strategies and the most-frequent strategy that is used in Little Women movie. Based on Brown and Levinson (1978), there are four types of politeness strategies. Those are bald on record, positive politeness, negative politeness, and off record. Descriptive qualitative method was selected to analysed the data. The theory that are applied in this study are Brown and Levinson’s theory (1978), which concerns about the politeness strategies. The result of this term paper was shown that all of the characters use all the politeness strategies from Brown and Levinson and the most frequent strategy that is used by the characters is positive politeness. The researchers hope that this research will help the readers to get a better understanding about politeness strategies based on Brown and Levinson.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
