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

This article illustrates on regional boundary stakes, the research that has been carried out so far is the manufacture of regional boundary stakes using GPS and GSM. This research has limitations, because not all regions in Indonesia have a good and stable GSM signal. Regarding this matter, the research on making boundary stakes prototypes was carried out using Wemos D1. The prototype of the boundary stakes does not use GPS or GSM, but uses the dbm / RSSI signal as a monitoring tool. The method used in this study uses a modified Triangulation method, compositions from Vincent Pierlot and Marc Van Droogenbroeck. This calculation method proved to be useful for finding Wemos D1 positions without using GPS and GSM devices. The results of research using the Triangulation calculation method proved successful in finding the position of Wemos D1 close to the actual coordinate position, besides the use of more Access Points in this study proved to be able to produce better accuracy.

Abstract

Di zaman globalisasi saat ini, sistem keamanan sangatlah penting mengingat intensitas kejahatan yang semakin meningkat seiring berjalannya waktu khususnya di komplek perumahan. Masalah yang terjadi adalah pelaku kejahatan sudah mengetahui teknis dari sistem keamanan yang terpasang contohnya adalah CCTV dimana alat tersebut menggunakan DVR sebagai media penyimpanan hasil rekaman, sehingga para pelaku kejahatan dapat dengan cepat menghilangkan jejak kejahatannya dengan cara merusak media penyimpanan tersebut. Maka dari itu, penulis membangun sistem keamanan menggunakan Raspberry Pi dan webcam dengan pengenalan wajah. Metode yang digunakan dalam membangun alat ini adalah metode Haar-cascade Classifier sebagai metode pengenalan wajah untuk mengklasifikasikan yang mana penghuni rumah dan orang asing dan pengiriman push notification ke telepon pintar para penghuni rumah sebagai peringatan bahwa ada orang selain penghuni rumah berada di depan rumah. Hasil yang didapat dari pengujian sistem keamanan yang telah dibangun menunjukkan bahwa sistem keamanan dapat mengenali baik penghuni rumah maupun orang asing dengan beberapa tes, yaitu tes pada saat siang pukul 14.18 sampai dengan 14.50 dan malam pukul 23.20 sampai 23.30, tes jarak antara webcam dan orang, tiga kali skenario pada saat datang kerumah baik penghuni rumah maupun orang asing, dengan beberapa orang tertangkap kamera dan notifikasi pada telepon pintar. Berdasarkan hasil pengujian dan analisis waktu siang dan malam, didapatkan persentase kesalahan untuk siang hari sebesar 35,2 %, untuk malam hari sebesar 74,3 %, waktu pendeteksian pada siang hari lebih baik dibandingkan dengan malam hari karena persentase kesalahan lebih rendah pada siang hari dibandingkan pada malam hari.

Abstract

In recent years, external smart charging, especially on laptop devices, has become quite an interesting topic due to the need for a response to a decrease in battery capacity and damage. As the development of embedded systems such as Arduino which is commonly used, this system offers more flexible data communication, which initially used cables to be wireless, ranging from Bluetooth to WiFi. As for this topic, there are controls based on the user's electricity needs and the condition of the electrical system, which is called dynamic demand control. The key to this method is the frequency of the electricity network and the battery. This method can provide extensions to smart charging to only charge when needed. The positive impact of using this method in addition to preventing the battery from being damaged is electricity savings. In this study the authors tried to study two models of the smart charging system schemes that have never been compared, namely the standalone and centralized models. The results of this study indicate that although the centralized model is more efficient in terms of reading the frequency value of the electricity network, in terms of performance the standalone model is more stable and reliable.

Abstract

In line with the large number of newcomers in Special Region of Yogyakarta, there have been many requests for boarding houses around the campus area. One sub-district that is geographically close to several universities is Mlati Subdistrict, Sleman Regency. Types of boarding houses are various, ranging from location, rental prices, and others. There are many types of boarding houses, ranging from locations, rental prices, and others. If someone feels uncomfortable with his/her boarding house, then he/she will often move around. Some of the reasons are: the more expensive rental rates, facilities, looking for other boarding houses that are closer to campus, and safety factor. Therefore, we developed a decision support system that can give an information about the best boarding house according to someone's need. It was created by applying the Simple Additive Weighting (SAW) method. The SAW method will generate a preference value. The alternative which has the greatest preference value will be chosen as the best alternative. The test results show that there is a correspondence between the value produced by the system and the value generated by manual calculations. Thus, the decision support system has successfully implemented SAW method and is able to function as its functions.
