Abstract

Queries are used for operations on information systems that use a database as data storage. The importance of queries should be a major concern at the application design stage. Generally the application designer ignores it so applications that are made will have poor performance when the data in the database is getting bigger. To overcome the decline in application performance because of neglecting query design, query optimization is performed. This study provides a solution to the declining performance of information systems by optimizing query information systems using stores procedures. The database in this study is designed by using MySQL Server 5 with 12 tables. The store procedure chosen in this study is function. There are 13 functions created with 12 functions for each table and 1 function to capture the status of the database operation processes.

Abstract

Stock stability in business activities is an important component. One way to maintain the stability of the stock of durian fruit is to estimate the amount of consumer demand for durian fruit. Predicting the amount of durian fruit customers need can be done by looking at the patterns formed from sales transactions. However, if the prediction is done manually, it will take a long time and be prone to errors. The solution to overcome this problem is the need for a tool in the form of software in which there is already an accurate calculation method. One method that can be used to calculate customer durian needs is the Adaline artificial neural network. And the training data used is durian fruit sales data. Training data is divided into 2 groups, namely input data and target data. The focus of this research is the pl/sql design to determine the data input pattern automatically for the application of predicting the number of customer's durian fruit needs. The types of pl/sql used in this study are procedure and function

Abstract

Anxiety disorder is one of the diseases are often encountered in psychology. Anxiety disorders can cause people into try to avoid situations that trigger or worsen their symptoms. There are several types of anxiety disorders, including Obsessive Compulsive Disorder. Obsessive Compulsive Disorder (OCD) is a disorder in witch people have recurring, unwaned thoughts, ideas or sensations (obsessions) that make them feel driven to do something repetitively (compulsions). The repetitive behaviors, such as hand washing and checking the door, can significantly interfere with a person’s daily avtivities and social interactions. Diagnosing what type of obsessive compulsive disorder do people have requires expert especially in psychology. An expert system is a system that requires the knowledge of an expert. This technology will help detecting the tendency of an obsessive compulsive disorder so people can enable to overcome and treat them appropriately. This system implements Forward Chaining to trace the knowledge base, which is consist of the type disorders, symptoms, and the rule. The expert system created by the author is based on a website using the PHP programming language and MySQL database. The output of this program is the name of one of the obsessive compulsive disorder and its solusions. It is hoped the expert system can facilitate and help the public to diagnose obsessive compulsive disorder

Abstract

Potorono Village is one of the villages located in Banguntapan District, Bantul Regency, DIY. Potorono Village has a total area of ​​435.46 ha. Potorono Village has several village land treasuries that can be rented by residents and certain agencies. This land lease is managed by a team of intensification of land leases in Potorono Village. The rental system has been done manually so far, so the recording and documentation is very poor. This condition is exacerbated by the determination of village treasury land tenants who are determined arbitrarily, without taking into account the agreed criteria. The transparency of the village treasury land rental is also questionable. This research provides a solution to the problem of renting village treasury land. In this study, a land rental recording system was built and the determination of village treasury land tenants was built. The method used in this research is the Oreste and Besson-Rank methods. The platform used in the research is based on Android and the programming language used is the PHP programming language. The database on the proposed system is built using MySql

Abstract

The educational process, which is supported by adequate laboratory facilities and infrastructure, will produce professional higher education tri-dharma outputs, both for students and lecturers. The Medical Equipment Laboratory is a place where experimental studies with various equipment and devices, analyses, and observations are carried out. The amount of electrical energy used by a university can be measured using an electric energy meter, namely the kWh meter, but the university cannot monitor which building or room uses the most electrical energy because it only knows the amount of power used each month. Given these problems, a digital kWh Meter monitoring tool based on the Internet of Things (IoT) is designed to measure the amount of current, voltage, power, and costs that must be incurred while using medical equipment and can then be monitored in real time using the Blynk application as the server. The implementation system for monitoring the kwh meter using the PZEM-004T sensor has a very good accuracy rate of 99.52% for measuring voltage and 99.87% for measuring current on medical equipment in the medical equipment laboratory at the PGRI Yogyakarta University. It was found that the greater the applied load value, the more the impact on data outputs such as current and voltage would affect the size of the monthly electricity bill. The monitoring system can be carried out within a radius of 20 meters as long as the smartphone is connected to a WiFi connection. Monitoring activities and electrical device control activities can be carried out.
