Abstract

Wind energy is one of the energy that is starting to be used to produce electricity or convert it to mechanical energy for other purposes. One of the tools used to harness wind energy is a wind turbine. Indonesia, especially Aceh, is one of the countries that has not used wind energy as a power plant because of the characteristics of wind in Indonesia which tends to be low-speed. Archimedes spiral wind turbine is a new type of wind turbine that can operate at low wind speeds, consisting of two to three Circular blades form an axis, then wrapped around each other and one side is extended, the design of this turbine essentially mimics the shell of the Nautilus snail (Biomimicry). The basic principle of this wind turbine is designed using the legal principle of Archimedes. This scientific work will analyze the effect of variations in the number of blades on rotation and the influence of blade rotation on wind speed using the experimental method, therefore turbines are made with variations of 2 blades and 3 blades, and the outer diameter is 80 cm and overall length is 90 cm. From the results of the study it was found that the 3 blade wind turbine has a better percentage of shaft rotation compared to the 2 blade wind turbine that is equal to 16.67%. Maximum wind power occurs on the 4th floor with a value of 164.3 watts

Abstract

A hydraulic ram pumps, or shortly known as a hydram, is a water-lifting device that operates automatically and continuously. It is a device that uses the energy in the flowing water such as spring, stream or river to pump part of the water to a height above that of the source. With a continuous flow of water a hydram operates continuously with no external energy source. Hidram pump design influenced several input parameters such as head, inlet pipe diameter and yield parameters: length of inlet pipe, heavy weight exhaust valve, the inflow speed, output flow rate and efficiency of the pump. In this study, the analysis is done using visual basic 6.0 computer program, as well as completion of the problem in terms of design of the hydram pump. The performance results are then compared with the experimental results. This program aims to ensure that everyone can design and make the hidram pump, with still follow the general rules of the proper design.

Abstract

Solar energy is a source of electricity for various industrial applications, such as water heating and drying. In the drying application, energy is transferred from one point to another due to the temperature difference of the sample material. This promoted the significant use of dryers by both farmers and fishermen to preserve their harvest or catch. However, there are several problems associated with the open system drying, such as inconsistent drying duration, dirt, fungus contamination, and rain. Therefore, this research aims to analyze heat transfer and airflow in the drying chamber of a tunnel-type application, using experimental and computational simulations. The general applied methods encompassed measuring the dryer’s in situ temperature, modeling the heat transfer, and analyzing the computational fluid dynamics(CFD) simulations for the airflow in the drying chamber between 08:00-15:30 GMT+7 (February 9, 2021). The temperature and airflow simulations of the system were analyzed and validated without a load of dried materials. Based on the measurement results, the minimum inlet and outlet temperatures occurred at 30.2oC (08.00 GMT+7) and 24ºC, similar to the simulation at 31.2ºC (08:00 GMT+7). Meanwhile, the maximum inlet and outlet temperatures were evaluated at 45.7 and 39ºC, with an outlet simulation temperature of 41.5ºC (12:00 GMT+7). These overall results indicated that the temperature values did not vary extensively. Therefore, the applied drying system is best suitable for post-harvest agricultural, forestry, and marine drying applications.
