The subsurface structures model can be made by various methods, one of which is the gravity method. The basis of gravity modeling is the difference in density of materials. This can result in ...gravitational anomalies. Overall gravitational anomalies are known as bouguer anomalies. The gravity anomalies can be separated into local anomalies and regional anomalies. This research was in Mount Kelud, Kediri, Indonesia. The gravity data was processed using Surfer 9 software for the manufacture of two-dimensional contours. After that, researchers performed anomaly separation through MagPick software. In this study, researchers compared the two-dimensional contour results of MagPick gravitational anomalies toward the reduction of bouguer anomalies to regional anomalies. As a result, both show the same accurate contour.
The development of an industrial product arises with various problems and product quality that has high value. One example of a product that needs to be redesigned is a wheelbarrow or handcart. The ...wheelbarrow is a simple material conveyance which is pushed by hand, one wheel and one operator through the handle. This research aims at an ergonomic and economical handcart, so as to produce a product that can be useful for medium-sized industries and can increase efficiency and increase work productivity. This research was carried out by redesigning the product as a development, where this product is usually used in a building called a traditional material conveying tool, then calculating the axle and pedal stress on a wheelbarrow. In this study it can be concluded that the wheelbarrow or wheelbarrow is designed more ergonomically with several changes including changes in the height of the stalk from the ground to minimize bending when lifting the wheelbarrow, changes in shape and size of the supports to accommodate various lifting positions, other things, changes in shape and the size of the body so that when lifting and pushing the wheelbarrow, the load is more balanced, the addition of a jack to make it easier for users to spill loads from the body, the addition of two rear wheels to make it easier to push the wheelbarrow, and change the handle to make it easier for users
This research aims to analyze: (1) quality of project based learning tool with trainer PLC, (2) the creativity of students after following the learning to use project based learning tool with trainer ...PLC, and (3) self-reliance learn student after following learning using project based learning tools with trainer PLC. This research is a research and development (R&D) using One Group Pretest Postest Design. The results showed that (1) the learning tools of project based learning with PLC trainer shows excellent quality with a score of 81.4%; (2) the creativity of students after implementing learning using learning tools of project based learning with PLS trainer has increased with the average value of N-gain of 0.60 criteria medium; (3) the self-reliance of the student learning increased after implementing learning using project based learning tools with PLC trainer, indicated by the average value of N-gain of 0.55 with medium criteria.
