Abstract

ABSTRACT Inflation is one of the economic phenomena that is always interesting to discuss mainly related to its broad impact on macroeconomics, such as economic growth, external balance, competitiveness, interest rates, and even income distribution. Inflation plays an important role in determining economic conditions, so it needs to get serious attention from various circles, especially the monetary authority responsible for controlling inflation. If inflation can be predicted with high accuracy, it can certainly be used as a basis for government policy making in anticipating future economic activity. This study aims to produce inflation forecast data. The method used in this study is the SARIMA method and Single Exponential Smoothing. In forecasting the rate of inflation where data is in the form of time series, the SARIMA method can show more accurate forecasting results than using the SES method. Based on the comparison of the overall forecasting model, the SARIMA model (2,1,1)(1,1,1) 11 has the smallest error value with a MAD value of 0.117, MSE 0.023 and 0.72% for MAPE. From these results it was collected that the inflation forecasting in Bandung using the SARIMA method has a high accuracy value. Key words: Inflation, Forecasting, SARIMA, SES

TIASA has a goal in several menu features that suit the company's business processes, from human resources to production processes. Based on the problems in TIASA information systems, especially in the production section, it is necessary to develop a production information system for PT XYZ using the TOGAF architecture development method (ADM) to integrate several parts of the production process. Based on the research results, the togaf framework design to support the development of PT XYZ's production information system using the togaf architecture development method (ADM) can provide blueprint guidelines and documentation for future developments. In this model, includes the scope of data architecture, application architecture, and technology architecture as an enterprise architectural design. Index Terms—Togaf, Architecture Development Method, enterprise architecture planning, textile, production, blueprints.

Abstract

The availability of goods in a store is very important. Forecasting is a tool that is used to help predict data needed by an organization or company. The purpose of this study is to predict the sale of a product that has a high risk of damage and fast expiration time by using existing techniques in forecasting. Forecasting can also be used to make product stock safety at the XYZ Supermarket. The results of this study are in the form of forecasting the sale of a product in a store by using the existing methods of forecasting that are adjusted to the sales data of one product. The method used in forecasting is the ARIMA method, Trend Analysis, and Single Exponential Smoothing. Trend Analysis Method has the highest accuracy with MAPE 9.91%, which means that forecasting is very good, compared to ARIMA with MAPE 37.21% and Single Exponential Smoothing with MAPE 10%. So that the results of the Trend Analysis forecasting will be used for the decision-making process about forecasting stockpiles and stock safety in the future.

Abstract

Universitas DIPA Makassar adalah sebuah enterprise yang memiliki beberapa unit bisnis yang berkaitan dengan kegiatan pembelajaran mahasiswa. Masing-masing unit bisnis tersebut memiliki sistem terpisah sehingga rawan terjadi masalah dalam pengalokasian sumber daya. Hal ini mengakibatkan data yang digunakan tidak konsisten. Untuk mengatasi masalah konsistensi data tersebut diperlukan pembaharuan sistem pada masing-masing unit bisnis pada perguruan tinggi. Adapun langkah pertama dalam pembaharuan sistem tersebut adalah perancangan sistem. Perancangan sistem pada penelitian ini menggunakan framework Enterprise Architecture Planning (EAP). Framework EAP dimaksudkan untuk membuat masing-masing unit bisnis yang dimiliki oleh perguruan tinggi menjadi terintegrasi dalam satu sistem terpadu. Sistem terpadu ini kemudian akan diterapkan menggunakan salah satu layanan berbasis komputasi awan yaitu Infrastructure as a Service (IaaS). Adapun layanan IaaS yang digunakan dalam penelitian ini adalah Amazon Web Service (AWS). Keyword : framework EAP, IaaS, AWS

Abstract

Sesuai dengan Peraturan Walikota Tanjungpinang Nomor 47 Tahun 2019 Tentang Penjabaran Tupoksi Organisasi, dan Tata Kerja Sekretariat Daerah dan Staf Ahli, Bagian Administrasi Pembangunan merupakan instansi bagian yang bertanggung jawab penuh kepada Asisten Perekonomian dan Pembangunan. Proses bisnis saat ini belum berjalan optimal terutama untuk monitoring dan evaluasi kegiatan pembangunan daerah. Pada aktivitas pengumpulan laporan realisasi dan pembuatan rekapitulasi masih dilakukan manual. Berdasarkan permasalahan tersebut, maka dirancanglah sebuah arsitektur enterprise untuk mendukung proses monitoring dan evaluasi pembangunan di Bagian Administrasi Pembangunan. Dalam penelitian ini, tahapan penelitian yang dilakukan berupa mengumpulkan data, menganalisis alur sistem, dan merancang aplikasi. Tujuan dari pengumpulan data agar mendapatkan data valid melalui teknik wawancara, observasi, dokumentasi, dan studi literatur. Mekanisme sistem saat ini akan dianalisis oleh value chain dan gap analysis. Pada bagian ini, perancangan aplikasi didasarkan oleh kebutuhan organisasi dengan menerapkan framework TOGAF ADM. Terdapat lima fase yang dibahas terdiri dari fase pendahuluan, manajemen kebutuhan, arsitektur vision, arsitektur business, arsitektur information system, arsitektur technology, serta opportunities and solutions. Adapun alat bantu pada penelitian ini yaitu UML dan BPMN. Dengan adanya usulan model arsitektur, dapat menjadi landasan kegiatan pengadaan dan pengembangan berbasis sistem informasi untuk monitoring dan evaluasi di Bagian Administrasi Pembangunan.
