Abstract

Data mining sebagai pengolah data telah diketahui bahwa data mining dapat menemukan suatu polapada basis data yang besar. Spatial data mining merupakan proses menemukan pola yang menarik danpotensial untuk dicari informasinya berdasarkan pola dari spatial dataset.Spatial data mining memerlukan neighbour object untuk mencari keterhubungan obyek itu sendiri denganobyek-obyek lain yang mempengaruhi obyek tersebut. Setelah neighbour object diidentifikasi maka associationrule dapat dicari.Pencarian neighbour object dilakukan dengan melakukan buffer dari obyek pencarian, sehinggaditemukan obyek disekitar obyek tersebut. Analisis spatial association rule menggunakan metode Apriori.Parameter ketetanggaan/kedekatan dari obyek adalah berdasarkan radius atau jumlah neighbour object.Semakin banyak neighbour object, semakin banyak frequent item yang dibangkitkan, dan semakin banyak pularule-nya.Kata kunci: neighbour object, spatial association rule, spatial data mining.

Abstract

Di setiap system database, kemungkinan terjadinya failure terhadap system dan hardware selalu ada.Sebelum terjadi failure yang mempengaruhi system database tersebut maka harus dipersiapkan system backupdari database tersebut. Tujuannya adalah untuk menjamin proses operasional harian yang penting bisa tetapberjalan, meskipun primary system sedang mengalami failure.Standby database adalah salinan dari database regular yang terinstal pada system yang terpisah. Jikafailure terjadi pada system primer, system standby itu diaktifkan dan mengambil alih proses, sehinggameminimalisasi efek dari failure yang terjadi terhadap faktor availability dan downtime. Oracle menjagastandby database agar terupdate dengan menerapkan archived redo log yang dikirimkan dari database primersecara konstan.Penelitian ini mengangkat analisis dan implementasi dari standby database dengan menggunakan dbmsoracle 9i. Akan dibuat juga suatu perangkat lunak pencatatan archived redo log dari primary database untukdibandingkan dengan archived redo log yang terdapat pada standby database serta simulasi transaksi berupaproses DML.Kata kunci: standby database, primary database, archived redo log.

Abstract

Abstract— Testing a software is an important stage of a series of software development. Functional testing of each feature on the Angkasa website is intended to try out the function to match the required specifications. To achieve a functional test result, there are elements of features on the web page that require keywords. These keywords are used to perform actions or actions in running a web page, these keywords will help in making Test Cases for the testing process. Because it takes the right keywords to test on the web. To overcome this problem, this study analyzes the use of the Keyword Driven Testing approach for making Test Cases through the Katalon Studio tools. Keyword Driven Testing is one of the concepts in ISO/IEC/IEEE 29119, namely Keyword Driven Testing in The Test Design Process. The results of the analysis show that making Test Cases with Keyword Driven testing is easier to understand and is fully supported by the Katalon Studio tools. However, when creating test cases, not all keywords can be added automatically, so they need to be added manually.

Abstract

Most developers still use the monolithic architecture, where all components of an application are combined into one integrated system, so each part depends on other components. The monolithic architecture has weaknesses, such as when a failure occurs in one component, all parts cannot be executed because each component relies on one other component. Microservices can be a solution to this, considering that in the microservices architecture, each element or service is created and put separately, so when a failure occurs in one component, other components will not be affected and can still run normally. This research aims to determine the implementation and performance comparison between monolithic architecture and microservices Architecture in the Agreeculture Market web app. Agreeculture Market is a web application that aims to facilitate the transaction process of agricultural commodities and make it easier for agricultural commodity producers to market their products. The measurement method used to measure the performance of both architectures is load testing using JMeter and performance tools from task manager and comparing the response time, throughput, disk usage, CPU usage, and memory usage of both used architectures. With two measurement schemes with Docker and without Docker, the result of this research is a performance comparison between the two architectures, where the backend application Agreeculture Market, which uses microservices architecture with Docker and API gateway, performs better than the monolithic architecture version. Conversely, the monolithic architecture performs better than the microservices architecture in the scheme without Docker and API gateway.
