Abstract

Paradigma perubahan kurikulum pembelajaran berdasarkan outcome base education pada instansi perguruan tinggi Universitas Mercu Buana akan merubah implementasi capaian pembelajaran sesuai dengan target kompetensi capaian lulusan. Dampak dari hal tersebut salah satunya adalah pemenuhan target kompetensi melalui sertifikasi pelatihan yang sesuai kepada dosen selaku pengajar yang sesuai dengan pembelajaran mata kuliah yang disampaikan kepada mahasiswa. Akan tetapi, dalam fakta yang didapatkan baru sekitar 22% dari total populasi dosen tetap pada fakultas ilmu komputer yang telah memiliki sertifikasi kompetensi yang sesuai dengan mata kuliah pengajaran, sehingga hal ini akan menjadi permasalahan ketika fakultas akan melakukan reakreditasi program studi. Oleh karena itu diperlukan suatu pemodelan database yang akan mendukung sistem monitoring kompetensi dosen dengan baik. Proses perancangan database akan menyesuaikan dengan pemodelan relasional database dengan dimulai dari tahapan konseptual, logikal sampai dengan fisikal desain serta dengan evaluasi normalisasi data pada perancangan database. Untuk mendukung pengembangan arsitektur data yang ideal maka digunakan pendekatan Framework TOGAF ADM. Tujuan dari penelitian adalah menghasilkan pemodelan database yang tepat terkait dengan rencana perancangan sistem monitoring kompetensi dosen menggunakan pendekatan TOGAF ADM. Hasil dari penelitian ini adalah pemodelan database dan enterprise architecture planning sesuai kebutuhan bisnis Fasilkom di institusi perguruan tinggi Universitas Mercu Buana.

Abstract

A query is a syntax or command used in a database system to access and display data. Queries can be used to make data interact with each other. To display query results in the database, of course, requires execution time which is usually denoted in seconds. Execution time is directly proportional to the amount of data to be displayed and the level of complexity of the database. To speed up query execution time, the term database optimization is known. One of the database optimization methods is to use the b-tree indexing technique the database. This study aims to compare the execution time of databases that have not been indexed or that have been indexed with data objects in the MySQL database MPN-Info application at the Jakarta Palmerah Tax Office (KPP Pratama Jakarta Palmerah). This application was developed to supervise taxpayers which is used in almost all tax service offices throughout Indonesia. The data used is active employee status taxpayer data registered until 2020 with the reporting of Annual Personal Income Tax Returns in 2019 and 2020. The study uses an experimental method by applying a select query, then the execution time is recorded well for unindexed and indexed databases. The gradient method will be used for compare the results of the two. The results obtained are after taking the population of taxpayers registered employees up to year In 2020 at KPP Pratama Jakarta Palmerah, 31,238 data were compared with the annual reporting data, the average execution time before indexing was 255.585 seconds and the average time after indexing was 1.341 seconds and the gradient value before indexing was 0.0211 and after indexing was 0.0001. This proves that the indexing technique has a significant impact in accelerating the query execution process.

Abstract

Microservices architecture, a distributed framework architecture that allows changes to one module without interfering with other modules. The implementation of this architecture has its own challenges. The get-list-attachment API running on this architecture takes an average of 12.5 seconds to serve data. This needs to be considered because business processes require shorter access times to support decision making. The research objective is to obtain query response time efficiency for accounting applications. To achieve this, the research uses database optimization techniques with logic execution optimization microservices architecture. This study obtained the source of information from the Accounting Harmony Accounting Module, which has an API (get-list-attachment) with data sourced from Service Accounting (581253 records) and Service Users (2182 records). Based on a series of tests carried out, several services need to be added with APIs to improve the microservices architecture to accept bulk parameters that generate a list of objects so that data presentation is more optimal. After doing a series of engineering on microservices architecture and indexing application, query response time performance increased by 49.22% for Service Accounting module.

Abstract

Setiap perusahaan payment gateway yang mendapat ijin operasional Bank Indonesia (BI), harus melaporkan data transaksinya setiap bulan ke BI . Permasalahan terjadi karena database transaksi produksi tersebar di banyak database, dimana database dipisahkan berdasarkan channel (merchant) dan payment type (Credit card, VA, retail store, e-wallet), hal ini  menyulitkan saat pembuatan laporan. Penelitian ini ditujukan untuk membuat data warehouse yang menggabungkan seluruh database  dengan menggunakan script PHP yang melakukan proses ETL (Extract, Transform, dan Load), dengan cara berjenjang  2 tahap, yaitu tahap 1 melakukan backup seluruh database dari banyak server ke satu server dengan 3 tujuan sekaligus yaitu  backup transaksi , meningkatkan  performance database production dan membantu  proses rekonsiliasi dan tahap 2 melakukan pembuatan data warehouse  dari semua database backup dari tahap 1. Penelitian yang digunakan adalah kuantitatif verifikatif terhadap table-table yang diperlukan  pada system OLTP (Online Transaction Processing). Pengujian data warehouse dilakukan  secara kuantitatif dengan membandingkan hasil summary dari data warehouse dengan gabungan summary  semua database aslinya  dan secara verifikatif oleh petugas report melalui User Acceptance Test. Hasil dari penelitian adalah sebuah script untuk backup data transaksi dari semua database dari banyak server ke satu server,   sebuah script PHP yang berfungsi sebagai pelaksana ETL dan sebuah  data warehouse.

Abstract

 This study addresses the pressing need to comprehensively manage air pollution by examining the roles of local and national public agencies from the perspective of the general public. Air quality poses a critical challenge that profoundly impacts various aspects of human life. To enhance our understanding and generate both theoretical and practical insights for public management, this research introduces several key variables: the engagement of authorities in mitigating air pollution, citizen involvement in pollution reduction efforts, financial incentives for individuals and businesses to adopt air-friendly behaviors, urban green investments, the communal consequences of air pollution, and the necessity for industrial participation. Employing Partial Least Squares Structural Equation Modeling (PLS-SEM) as the research approach, data was gathered from residents of Indonesia's largest cities, where pollution significantly affects society and governing bodies. The findings are pertinent for public managers at both local and national levels, providing valuable input to enhance strategies for curbing air pollution, enhancing air quality, and ultimately improving the well-being of inhabitants.

Abstract

 Based on CHAOS 2020: Beyond Infinity Overview, reported by the Standish Group, only 31% of  IT projects were successfully implemented, while 50% of projects were challenged and 19% of projects failed. Many project managers less awareness about SRM and have a partial understanding of risk. The purpose of this study is to develop a project risk management framework for listing companies in the information technology sector. The sample for this study is 35 annual reports of technology companies listed on IDX. This study identified 122 types of project risks from 33 companies' annual reports. This study uses an exploratory study approach. The proposed framework includes three stages, namely the root cause, risk assessment, and performance stages. At the root cause stage, the identification of risks from elements of the business environment becomes the basis for measuring risk treatment. In the next stage, the identified risk treatment is measured through identify, analysis, and verification activities with the support of communication, documentation, and evaluation. The measurement results are classified into three major dimensions, namely cost, time, and quality. The final stage of the framework is in the form of residual performance risk and a risk mitigation action plan.
