Abstract

The process of character building for early childhood students is not optimal due to lack of communication between parents of students and teachers. This lack of communication  is caused by teachers' fear of being violating human rights when giving educational punishment or warning to students who have broken the school rules (are not disciplined). To overcome this problem there needs to increase communication between teachers and parents of students, so there is no misunderstanding of the information received. An android-based application is used to facilitate communication between parents and teachers. This application has facilities in the form of information on student violations records, activities at school, tasks that must be done at home, and the amount of attendance. By using the application, parents can monitor and be notified related in real time. The location of this research was conducted in elementary school. SD.

Abstract

The case in the metal casting process is when the metal is melted and then poured into a liquid metal reservoir and then poured into a pouring tool and then poured into a mold. In the process of pouring into the mold is still using manual equipment, namely by using wood which ends have a container such as a bucket ( bucket)) made of a mixture of white cement, brick fire sand and clay and the metal liquid pouring tool has a length of 1.5 cm, a weight of 5 kg with a diameter of 15 cm and a height of a container for liquid metal 20 cm does not include the load. If the pouring device filling with liquid metal, then the weight reaches ± 20 kg, with a weight of ± 20 kg the worker must pour the liquid continuously into the mold and at least each worker must go back and forth 6 times pouring metal liquid into a mold in a single combustion process. Based on the nordic body map questionnaire data as many as 8 workers felt pain in the shoulder and arm because the burden was born, resulting in workers often feel pain in the muscles of the arms and back. Because the wooden handle used to pour metal liquid is too slippery (exposed to sweat), so there is a need for improvement in activities. From the results of the above observations, it is necessary to design ideas for new work facilities. It expects to affect the improvements related to the position of the hand in the process of pouring liquid into the mold. Then the design idea needs to be done in the form of a casting tool that has been modified and can be used according to user needs and can be said to be ergonomic, safe, and comfortable. The method used in designing castings is quality function deployment and anthropometric techniques.

Abstract

A database server called the Database Management System (DBMS) that relates tables in a database is called the Relational Database Management System (RDBMS). DBMS/RDBMS is a computer program that provides data services for computers or other computer programs. One of the RDBMS type database server (hereinafter referred to as a database server) is MariaDB. The database server is in charge of managing and providing data, so data must always be ready, fast presented, accurate, and safe, it cannot be damaged or even lost. One way to provide this data is to install several database servers using the concept of replication in the Multiple Server Database system. Replication in a cluster server database is a method of installing several database server nodes that allow between node servers to copy each other and distribute data from one node to another database server node, which then synchronizes data between server nodes to maintain data consistency. This study looks for the most optimal number of minimal database server nodes to provide accurate, fast and safe data on the MariaDB Cluster RDBMS. From the results of the replication test from the cluster server database, it can be concluded that the number of 3 (three) node servers can be known to always synchronize and consistency of data between server nodes, so there are 3 (three) nodes of minimum database node with MariaDB RDBMS.

Abstract

The Supporting System The decision to control basic food prices at the fisheries and forestry service is a system designed to assist relevant agencies in seeing prices of basic necessities which tend to increase at any time. At first the relevant agencies do recap calculations by storing data and still counting manually, so it requires a longer time, with the existence of this system it is expected to be able to help and provide solutions for consideration of decision making in accordance with the right calculations.The decision support method of calculation used is the SAW method that takes the greatest value to be used as a decision-making ranking. In addition, other methods used are data collection methods by observation and interviews to identify problems in developing support systems for basic food price control decisions. Model design is described using data flow diagrams (DAD) and entity relationship diagram (ERD).The system developed is able to record, calculate and provide alternative solutions effectively for relevant agencies. With this system, agencies are expected to be able to process the calculation of basic food prices better, select more accurate decisions, and take more effective alternative solutions.
