Abstract

The use of energy in Indonesia currently has a growing need for energy, this will have an impact on the condition of the energy crisis, dependence on fossil fuels has a very serious threat, therefore there must be alternative energy as a substitute or as a saver of fuel reserves. Currently available fossils such as wind energy, water energy, and solar energy are very abundant in Indonesia. This study aims to develop wind power plants as a source of alternative energy to produce electrical energy, namely wind turbines. A wind turbine is a tool that functions to convert wind power into mechanical power in the form of a shaft rotation, then this shaft rotation is utilized for power generation. This tool is used to meet energy needs and is also used for alternative energy as an effort to save and reduce dependence on fossil energy. In this problem, the author will develop a tool for the influence of the wing tip of the rotor blade on the performance of the wind turbine. The purpose of this research is to calculate how much influence the wing tip has on the performance of the wind turbine on the electric current produced by the wind turbine. By adding variations to the wing tip using NACA 0021. The data obtained in this study are current (A), voltage (V), turbine power (watts), from the results of the research data it was found that the performance of the wind turbine using NACA0021 was the most optimal using a wing tip. at an angle of 15〗^0 in layer 2 with a voltage value of 12.5 (V), current 2(A), turbine power of 25.35 (watts), and efficiency of 0.844.

Abstract

This research is entitled Analysis of Photojournalism by Aji YK Putra (Study on Kompas.com Reporting: The Story of Treasure Hunter Divers in the Musi River) with the aim of the research to tell the public how the procession of searching for treasure in the bottom of the Musi River includes what items are obtained during the hunt and equipment used by divers when searching for treasure. Photojournalism is a visual work that displays a message through an image based on facts without engineering. The Musi River has a depth of 12 to 30 meters with a target for hunters, namely at a depth of 30 meters. The Musi River treasure hunters are a group of people who depend on their prey for what they get. Aji YK Putra as a photo reporter did in-depth coverage of a group of hunters on the Musi River so that they got some data about how dangerous hunting is carried out by divers by risking their lives on a breathing apparatus assembled from a compressor hose. From the data studied through Roland Barthes' semiotics, several research results were obtained which described the field conditions of hunters when diving in the depths of the Musi River. This research also proves that journalistic photo products are able to express objectivity towards an event that exists in society because the photo displayed is an image with a million meanings.
