Abstract

On the development of the database currently has become a very important thing, each will plan something, consider any thing we will need and use existing data in a database, The development of the database currently has become a very important thing, when we want to plan something and consider everything, we will need and use existing data in a database, PostgreSQL is one Object Relational Database Management Systems (DBMS) open source with a lot of features that are not less sophisticated to commercial databases. On daily use, it sometimes occurs a case that requires a dynamic column, therefore we should make the new columns to meet those needs. However, if each row of the table column requires different column and potentially need another ones, then it is going to be useless. On the research of utilizing the technology of JavaScript Object Notation (JSON),Json_encode PHP programming language can simplify the use of the column so that a new column is no longer needed when we want to create a new column on the table, we only need a new column that stores an array that has been converted into a JSON string forms the result of json_encode that represents the column name and the content of the columns of a table.

Abstract

Elderly is a last transitional period of human life. Decrease or disappearance of organ function such as loss of balance, reduced vision and hearing cause the elderly often fall. The limited physical ability of them requires supervision. Supervision is necessary to avoid undesirable thing occurs. Here, a tool called accelerometer can be used to supervise and monitor whether the fall incident occurs or not to the elderly. In this study, the magnitude of the acceleration in x, y, and z axes of the accelerometer sensor is processed into a total value of acceleration. Then the value will be compared with the lower threshold value and the higher threshold value. After that the total value of the acceleration is compared again with the threshold value of the total value orientations. The total value of acceleration is used to distinguish between regular activity and falling. The results of this study indicate that the system developed has the sensitivity values of 89% and specificity of 98%.

Abstract

The weather prediction tool is a microcontroller-based automatic weather monitoring tool that can monitor changes in temperature, humidity, air pressure through sensors that have been placed and programmed to detect weather conditions around the monitoring location. This tool is designed to be able to monitor and manage data from anywhere in the area where this tool is placed as long as there is an internet connection. To add flexibility, the sensor data processed on the ESP32 microcontroller will be connected to an access point on the 2.4 GHz wireless network, then the data will be sent to the web server and will be displayed on the website. The focus of making this weather prediction tool is that it is hoped that with this weather prediction tool, factory owners can be assisted in the process of drying the grain, so that the dried grain can be peeled off and can be processed using a grinding machine to be sold to consumers in the form of rice.

Abstract

Wedding Organizer itself is one of the special services that helps the bride, their families in planning and supervising the implementation of the entire events of the wedding plan according to a predetermined schedule from the wedding ceremony, traditional ceremonies, aisles, etc. Such as the Imagine Wedding Organizer which is one of the cases in this study. In Imagine Wedding Organizer, the system used is still manual. Therefore, in this final report the author provides suggestions in the form of ordering web-based computerized Wedding Event Services. Where the system design uses Unifeld Modeling Language (UML) with the Hypertext Preprocessor (PHP) programming language, MYSQL database, and uses the Waterfall system development method and uses a system testing method called the BlackBox Testing Method.

Abstract

Warung Mbak Sih is engaged in the culinary field that serves home cooking such as mixed rice, spicy chicken rice, soup rice, sour rice, fried chicken rice, rawon rice. Lots of customers who buy on the spot or order to be packaged. With the application of ordering food at online stalls, the number of visitors queuing can be limited so that they are not too many. The preparation of the application has been done well by using the HTML and PHP programming languages, as well as the Bootstrap framework. The database used with XAMPP software to manage sata is in the form of the SQL framework Bootstrap language so that it displays good display results both in desktop form and in the form of mobile phone pages. With the ordering application, the time used by buyers at the shop is faster, because orders have been prepared in advance. In addition to ordering the application also displays a variety of good information for stall sales.

Abstract

Endless runner Game is a Game where the player will move continuously indefinitely to get the highest point in the Game. Endless runner Game is synonymous with challenges in the form of obstacles and collective items. This study focuses on setting challenges in the non-playable character (NPC) behavior so that they can provide more dynamic challenges. Obstacle, player and NPC settings use the Finite state Machine method which is implemented in an html 5 based Game engine Construct. The implementation results are in the form of an html 5 Game which is then tested through 2 testing stages, namely blackox testing and beta testing. The test results using blackbox testing show that all functionality in the Game can run well, including the behavior of NPCs based on the designed FSM. Beta testing shows that the majority of respondents who have played endless runner Games stated that they like horror Games with local content nuances and the impression of humor and that the average Game difficulty level based on NPC responses to players is 63.75%.

Abstract

Many residents in the village of Entalsewu, Buduran District, Sidoarjo Regency, often complain about the situation in the village. Complainants do not know where to go to convey their complaints in the village environment. For example, roads that are damaged and have potholes due to frequent vehicles and extreme rainy weather along the roads in Entalsewu village and also the dead and dim public street lighting (PJU) have not been repaired so that road users experience accidents at night, many residents' houses flooded water that enters the house. Therefore, to overcome this problem, the author designed a village complaint application system based on android webview with a case study of village development. Which aims to make it easier for the public to make complaints in the village of Entalsewu, Buduran District, Sidoarjo Regency. This android application can be used by the public to make complaints online. This application can also make it easier for the village government to respond to community complaints. In this study, the author uses the Waterfall method as a process or flow of research results.
