Abstract

The tower structure of a wind power plant must be able to support other parts such as wind turbines, gearboxes and alternators. Thus the tower structure must be designed to be strong to withstand the heavy loads of other components and more specifically wind loads that can bend or break the tower structure if it is not strong enough.The purpose of this research is to calculate the load on the tower and design the tower structure for the L-type savonius wind turbine. Next, make a miniature tower to complete the miniature wind power plant which is the object of research.The tower structure is designed using pipes with dimensions; 2500 mm high, 203.20 mm outside diameter, 183.2 mm inside diameter, and 10 mm thick. The gearbox holder is made of 50 mm x 50 mm hollow steel with a thickness of 1.8 mm. The results of the static simulation of the tower structure using Solidworks 2016 show that the maximum von Mises stress is 1.33 MPa, and the maximum displacement is 1.84 mm.The designed tower is implemented in a miniature with a scale of 1:5, has a height of 50 cm and a pipe diameter of 2 inches, the gearbox holder is made of S 45 C strip steel with a size of 17 cm x 5 cm and a thickness of 5 mm. Keywords: PLTB, L-type savonius wind tower structure, Static simulation

The spur gear design application is made using the Python programming language. Making the software begins with manually designing the gears and continues with the design of the application. Application testing is done by comparing the results of gear design manually and using the application. Based on the tests that have been done, the results of the application design data have a value that is not much different from the results of manual design. By using the application that has been made, the time to design spur gears is shorter than manually designing spur gears. After the spur gear design application has been tested, it can be concluded that through this research the spur gear design application using the python programming language has been successfully created.

Abstract

The performance of a microhydro turbine is influenced by several factors such as the design process and the environment. The Archimedes screw is chosen for its excellence in converting the kinetic energy of the flow into mechanical energy in low-flow conditions. This research aims to design the Archimedes screw, gearbox, and calculate the generated power. The design methodology includes turbine design, flow simulation, and stress simulation. Additionally, the gearbox is designed to optimize the resulting rotation. The design results indicate that a turbine with a diameter of 0.45 m can operate at an average speed of 4 m/s, resulting in a turbine rotation speed of 169 rpm and a power output of 5076 watts. By using a generator efficiency value of 95%, the power output generated by the generator is 4822 watts.

Abstract

The role of developers is crucial in addressing the housing requirements of low-income communities; they have made an effort to construct basic houses at a reasonable cost. The majority of low-cost houses in North Sulawesi are equipped with zinc or metal roofs, which frequently result in the residents experiencing excessive heating and discomfort. The Community Partnership Empowerment team has installed roof ventilation and incorporated radiative insulation technology in this activity, utilising recycled cardboard. These two technologies have the potential to substantially reduce the temperature of the attic and the room, as indicated by the research findings. The initial phase entails the identification of the needs of novice home builders, the dissemination of information regarding roof ventilation and radiative insulation technology, the provision of training to builders, the construction of houses that incorporate these technologies, the provision of marketing support to developers, and the conduct of evaluations only after production. The outcomes of each of these stages have been documented, including the misconception that the construction of a comfortable and energy-efficient low-cost house will necessitate a substantial outlay. Consequently, the team disseminated the information through technology applications that did not necessitate substantial expenditures during the dissemination phase. The contractors were instructed by the team on the installation of roof radiative insulation, the production of radiative insulation panels, and the installation of roof vents. The subsequent phase involves the construction of a high-quality, energy-efficient, and cost-effective residence. The primary consumers of low-cost houses are the majority of daily employees from government offices, the TNI, and the National Police, as well as a limited number of civil servants. Consequently, we are committed to improving our marketing initiatives by concentrating on the following: preserving the company's brand, guaranteeing the quality of the homes we sell, collaborating with the appropriate agencies of the Ministry of PUPR, and facilitating infrastructure in residential areas through government subsidies, banks, and other related elements. Once the marketed products have been constructed, we evaluate this program. The program's objective is to make a substantial contribution to the mitigation of climate change by reducing carbon emissions. It ensures the comfort and energy efficiency of residents in a cost-effective residence by prioritising their material and non-material well-being.

Abstract

Water supply is a crucial factor for farmers in managing agricultural land, especially those relying on river water sources. The lower position of rivers and the considerable distance from the fields often pose challenges, making water pumps powered by electricity or fuel a common choice, despite their high operational costs. To address this issue, the utilization of renewable energy through the use of a spiral pump powered by a water wheel is proposed. The spiral pump is considered an environmentally friendly technology as it does not require electricity or fossil fuels. This study aims to analyze the head of a spiral pump based on the parameters of an undershot water wheel as preparation for the design of the spiral pump. In this study, a significant decrease in discharge value was observed from a head of 0.5 m up to a head of 3 m; in contrast, from a head of 3 m to 10 m, the discharge value decreased gradually. For small agricultural land or household needs, this spiral pump water wheel would be suitable at a maximum head of 5 m with a discharge value of 0.53 L/s. The results show a negative correlation between the head of the spiral pump and the discharge produced, where an increase in head results in a lower discharge.

Abstract

One of the uses renewable energy is the use of a spiral pump with a water wheel as the driving force. Spiral pumps are classified as environmentally friendly technology because they do not require electricity or fuel. The spiral pump consists of two main parts, namely the water wheel and the hose that is wrapped around both sides of the water wheel.The aim of this research is to analyze the water discharge of a spiral pump based on fluid flow simulation in the hose. This research utilizes advances in computational fluid dynamic (CFD) simulation methods using software.The determination method proposed in this research has been applied to a waterwheel model with a diameter of 1.2 m and a width of 0.6 m. For hoses, diameters of ½, ¾, 1, 1½, and 2 inches are determined, while the river flow speed is 0.9 m/s. For a hose diameter of 2 inches, the initial flow velocity in the hose is 0.38 m/s and the final velocity at the hose outlet is 0.452 m/s. The largest pump discharge was obtained at a hose diameter of 2.0 inches, namely 0.00183 m3/s.
