A belt tool typically has a random orientation of abrasive grains and grit size variation for coarse or fine material removal. Degradation of the belt condition is a critical phenomenon that affects the workpiece quality during grinding. This work focuses on the identifation and the study of force and vibrational signals taken from sensors along an axis or combination of axes that carry important information of the contact conditions, i.e., belt wear. Three axes of the two sensors are aligned and labelled as X-axis (parallel to the direction of the tool during the abrasive process), Y-axis (perpendicular to the direction of the tool during the abrasive process) and Z-axis (parallel to the direction of the tool during the retract movement). The grinding process was performed using a customized abrasive belt grinder ...

Whole cow's milk is a type of milk that contains a lot of nutrients and does not go through a lot of processing. As a result, pure cow's milk is very beneficial to the body, such as assisting child growth, assisting in weight gain, maintaining heart health, increasing muscle mass, and many other benefits. However, the benefits will be diminished if the cow's milk consumed is of less good quality. Feed is one of the many factors that influence the quality of milk produced. However, feed comes in a variety of varieties, as do those in The Hamlet of Sepaku Pamulihan Subdistrict, which has a variety of feed. Cooperative Tandangsari is one of the cooperatives in charge of managing dairy farms in the Sepaku area. Because the various types of feed in this area are so diverse, determining a good feed for dairy cows is difficult. As a result, this study was carried out in order to identify the best type of feed for improving milk quality. The forward chaining method is used in this study to determine the type of feed for cows, and feed type identification testing is performed using the WEKA application. The test result has an accuracy value of 71.5 %, precision of 0.714, and recall of 0.652, where the type of forage feed that can improve milk quality includes elephant grass, king grass, rice straw, and corn, among others.

Router can route packet because there is a routing table in router configuration. Routing table is anaddress list of source and destination address where the packet will be routed. There are two methods of routing tableconfiguration, static routing and dynamic routing. Static routing is a routing table configuration method where all ofrouting table content is configured manually, usually for a small scale of network. Dynamic network is a routing tableconfiguration method by the router automatically, usually for a big scale of network. A dynamic routing is built fromthe routing information collected by the routing algorithm. There are two routing algorithm, link-state and distancevector algorithm. This simulation will be built in GNS3 simulation software. Goal of this research is to compare theperformance between that two algorithm from two routing protocol that using each ...

One method for solving TSP is the Ant Colony Optimization (ACO) Algorithm. ACO is inspired by ant behaviour in searching for food, where ants produce pheromones to find food sources and make a route from the colony to food that will be followed by other ants. However ACO has not been considered as the optimal method for resolving TSP. This is because ACO has several shortcomings in the computational process. Comparisons between pheromones are not yet clear, and slow computing time causes the results of ACO to be not optimal. To correct these deficiencies, modifications will be made to the ACO. Modifications are made by changing some values in the ACO, such as adjusting the number of ants by the node automatically, changing the value in the pheromone renewal, and adding value to the construction...

Dari banyaknya kasus penculikan yang ada, kejadian lebih sering menimpa anak-anak. Sayangnya, kesibukan para orangtua untuk menghidupi keluarganya menjadi salah satu penyebab longgarnya pengawasan orangtua terhadap anak-anak mereka, terlebih lagi anak-anak sering kali berbohong untuk mendapatkan izin dari orangtuanya pergi ke suatu tempat. Oleh karena itu dibutuhkan suatu alat bantu untuk memantau anak dengan konteks kesibukan orang tua yang luar biasa tinggi. Hasil dari penelitian ini merupakan suatu aplikasi yang dapat melacak keberadaan anak secara realtime. Aplikasi ini dibuat menggunakan android studio dengan memanfaatkan location base dan Google Map sebagai peta dan landmark untuk menandai posisi keberadaan anak.

Actions taken by an Intelligent Agent with less optimum algorithm can be figured out easily by the player competing with it. This certainly makes it easier for the player to win the game. Card Battle is a game that compares the strength of both card decks. They competed to determine who has the best cards on deck to reduce the enemy health point. Intelligent Agent need to act as the competing enemy called Non-Player Character (NPC). Presently, Intelligent Agent on Card Battle Games still use the Minimax Algorithm. This algorithm thinks only to counter enemy summoned card without considering other things such as enemy health point left, the cost for summoning a card, etc. Improvisation of Minimax Algorithm with Multi Criteria Decision Maker (MCDM) provides a new way of thinking for the decision making during the game. The results of this study increase the difficulty of the NPC by makin...

PT. GOLDLAND REALTY already uses innovation such as augmented reality to deliver visualization on their property building product knowledge, but the software shows a lack of interaction between sales staff and customer. Around 80% costumers tend to stop using the software within less than 5 minutes, which shows that customers are not enjoying the software enough. This paper proposes a solution which is capable of improving interaction on augmented reality with a user using User Centered Design (UCD) approach to a property developer building. The result showed that by using augmented reality and User Centered Design (UCD) approach, customers experienced more interaction with the software and gain more valuable product information while interacting.

The use of path planning is not only applicable to robots and other machines that have the ability to move. C-Theta * is a new path planning algorithm with speed and better planning results compared to its predecessor, the A * and Theta * algorithms. Of course, as the new algorithm C-Theta * has no further research on the prospects for future implementation, so researchers cannot know whether this algorithm can be implemented in the research. This study aims to provide a review of C-Theta * by using the comparative method, for comparing C-Theta * with a path planning algorithm and analyzing cases in other studies. To find out the possibility of implementing this algorithm in the test cases. The results of this study prove that C-Theta * has similarities with grid-based as A * and Theta *, making it possible for C-Theta * to work on A * algorithms and other grid-based algorit...
