Abstract

The Indonesian coastal line is the largest in the world and has potentially large number of coastal natural resources, such as fish, seaweed etc. However, the Indonesian fishermen, particularly the traditional ones, have always been facing the hard and mediocre life. The situation was derive a specific research whit long-term goal was an attempt to facilitate the traditional fishermens with better tools in order to increase their income. The specific target was designation and implementation of simple and applicable small boat pulling apparatus to cut down the time needed to move the fishing boat on and off shore. It is no doubth that the introduction of the tool will improve the fishermen operation effectiveness and efficiency. Furthermore, the execution of ideas, manual calculation and raw design drawing along with Autodesk Inventor simulations software has been able to produce a model assembly of boat pulling apparatus. The design prerequisite was based on the results of comprehensive series of surveys related to the West Nusa Tenggara coastal conditions which was steep coastal with slope of 15-30 degrees as well as the simplicity of design needed by the fisherman. Based on the results of static analyse with finite element analysis (FMA) and dinamic analysis, the resulting design meets the shafety design requirements. Finally, the design can be said in the safe category and can be used safely in such conditions without harming the fisherman. Finally, this apparatus will economically improve the fishermen traditional life.

Abstract

Disruption to the transfomator can result in losses that disrupt the flow of electricity toconsumers. Harmonics are disturbances that arise due to the operation of non-linearloads. The purpose of this study is to analyze the efficiency of the KA4214 transformerat the Udayana Bukit Jimbaran Engineering Faculty with harmonics, namely the R =16.9%, S = 13.8% and, T = 16.1%. . The method used is to simulate and analyze withthe results of harmonic measurements in existing conditions, active filters, and activefilters based on fuzzy logic controller using Matlab software. The optimal resultsobtained are using the fuzzy logic controller method with the results of R = 0.85% S =0.65% T = 0.39% and the efficiency results are 99.99%

Abstract

Aviation technology and space is one of the leading technology for developed countries, especially in the form of rocket technology and payload. Countries that are capable of mastering these technologies will be respected by countries all over the world. Indonesia as the island nation and the State's large and extensive maritime already should have independence in the mastery of the technology of the rocket and payload. Therefore, continuous efforts are required to achieve independence, including through enhancing aviation technology and space technology, particularly at early stages the rocket and payload. Remote Sensing Systems At the rocket's Payload was Test remote monitoring system image capture and the attitude of the launch payload through the computer screen (display) continuously (real-time) data obtained from sensors that are mounted on the rocket's payload. 3D point (x, y, z) must be expressed as a graph visualization perspective drawings of rockets with the appropriate direction. The radar conducted computer GS (Ground Segment) or Ground Control Station (GCS). The result of the attitude of the Rocket Test launch Payloads have been able to do the communication data transmission of images and data for 3D (x, y, and z) in real-time to the Ground segment. Wireless communication uses radio telemetry frequency 433 MHz, power of 100 mW, the distance range obtained in this study a maximum of 1000 meter in conditions in the air and without obstruction.
