Abstract

The aim of the research is to establish the design of the trainer kit project to determine the effect of the rope material type toward the rope wave velocity and the effect of the type of nylon, raffia, polyester, hemp and chinnese satin rope materials on the velocity of rope wave propagation. The research method used is the Research and Development method using Nieveen design. The development of trainer kit uses an Arduino UNO microcontroller equipped with a proximity sensor HC-SR04 for measuring the rope wavelength. One point of the rope is tied with a timer ticker and the other is tied to a hanging load which is resting on a pulley. When the power supply is turned on, the timer ticker will vibrate to move the rope that has been tied. The rope will form a transverse wave. The result of this research, the design of trainer kit is development by using micro-controlled Arduino UNO and a proximity sensor HC-SR04 can be declared as a valid result. There are mass convention impacts of the type of rope likely nylon, polyester, raffia, hemp and chinese satin toward the rope wave velocity.

Abstract

Flood disasters often result in negative impacts, including damage to property, infrastructure, and loss of human lives. Identifying flood-prone areas and implementing appropriate prevention measures can significantly reduce its adverse effects. Mapping  potential flood  plays a key role in land use planning, early warning systems, emergency response, and flood mitigation efforts. In recent years, the Bedadung Watershed has faced issues of fluctuations in water discharge and it has a potential to cause flooding in Jember regency. This study aims to assess the flood vulnerability level in the Bedadung Watershed using parameter’s scoring and weighting methods, followed by an overlay or merging of each parameter. The research findings indicate that parameters influencing flood potential in the Bedadung Watershed are land use and land cover, slope and elevation area, and soil type. The results showed that the areas which are identified as vulnerable and highly vulnerable are mainly located at low elevations (0-500 m) with tend to be safe from occurring flood even though the level of rainfall is high. On the other side, the vegetation cover areas showed the low vulnerable from flood.
