    Seasonal Time Series Forecasting using SARIMA and Holt Winter’s Exponential Smoothing

    Authors: Pongdatu G.A.N. ; Putra Y.H.

    DOI: 10.1088/1757-899X/407/1/012153

    Abstract

    The purpose of this study is to compare SARIMA and Holt-Winter’s Exponential Smoothing methods in an attempt to generate customer transaction forecasting in Store X with high accuracy.This study will compare the results of sales forecasting with time series forecasting model of Seasonal Autoregressive Integrated Moving Average (SARIMA) and Holt Winter’s Exponential Smoothing method. SARIMA model still accurate when the time series data is only in a short period, this model is accurate on short period forecasting but less accurate on long period forecasting. Meanwhile Holt Winter’s Exponential Smoothing accurate on forecasting seasonal time series data, either it’s pattern shows trend or not. Both models are compared with forecasting data showing seasonal patterns. The data used is the data of clothing retail store sales from 2013 to 2017. Accuracy level of each model is measured by comparing the percentage of forecasting value with the actual value. This value is called Mean Absolute Deviation (MAD). Based on the comparison result, the best model with the smallest MAD value is SARIMA model (1,1,0) (0,1,0)12 with MAD value 5.592. From the comparison results can be concluded that the SARIMA model is feasible to be used as a model for further forecasting. © Published under licence by IOP Publishing Ltd.

    Authors: Effendi D. ; Januar A.R.R.

    DOI: 10.1088/1757-899X/662/3/032012

    Abstract

    This study aims to further optimizing online shop businesses by using Qualitative method in the research which resulted in more in-depth understanding in online business. With the rapid development of technology today, most young entrepreneurs online shop businesses are still using web media and not many people know. To expand an article and increase consumers, the online shop young entrepreneurs are looking for ABC social media applications. Where the target is a celebrity, because the program is more widely known to the youth to look for items to be searched for and which are discussed, liked or even used by most people at that time. Instagram is an application that includes a lot of interest with its users. A few people who have a lot of followers or followers are called celebgram. From these services they benefit by promoting an online shop so as to facilitate the online shop to get consumers, and can make it easier for consumers to find an item they want to look for.

  • Designing Authorization Procedures for Multi-channel and Public Participation-Based System Architecture for Civil Registration and Population Data

    Designing Authorization Procedures for Multi-channel and Public Participation-Based System Architecture for Civil Registration and Population Data

    DOI: 10.1088/1757-899X/662/4/042017

    Setiawan A. ; Kerlooza Y.Y.

    Abstract

    This paper aims to propose authorization scenarios for updating population data systems that involve public participation through several different telecommunications channels, called Multi-Channel and Public Participation (MPP)-Based Population Administration System. This paper reveals a number of important technical aspects that arise and must be considered in the authorization scenario. This paper also discusses broadly the authorization techniques that have been used separately in many previous cases. Conformity methods between behaviour of important technical aspects of MPP-Based Population Administration System and authentication methods that are commonly used in system implementations is the base for supporting the implementation of authorization scenarios. The proposed authorization scenario is to utilize a combination of Claim-Based and Multi-Factor authentication techniques because it has a match between important aspects and technical authentication. The combination of authentication techniques in the authorization procedure is able to verify and validate and determine the role of those who wish to collaborate in the service process. © 2019 IOP Publishing Ltd.

  • Application of (Genetic – Tabu Search) Algorithms for Subsequent Lease Schedule

    Application of (Genetic – Tabu Search) Algorithms for Subsequent Lease Schedule

    Author: Kinasya V.

    DOI: 10.1088/1757-899X/407/1/012124

    Abstract

    Submission of information relating to college scheduling in college is very important and is usually done on a semester by the academic section. One of these universities is Universitas Komputer Indonesia (Unikom) which became object of case study. In deterMining the scheduling of many aspects that must be considered include the components of the course, lecturer, class, space, and time. All of these components are considered so that the schedule of lectures that will be formed does not happen clashing with each other. In addition, scheduling problems will be more complex if there are many additional terms or constraints. In this study aims to be able to make lecture class scheduling replacement with a combination of genetic algorithms and tabuo search. The first step is done by separating the hard and soft constraints that exist in the lecture problem, and then the best individual search is done by cross-over or cross-breeding process to produce new individual and perform the process of mutation or exchange of individual position in order to produce the best fitness value of the previous individual. The advantage of using a tabu search algorithm allows for the absence of duplicate individual processes. Therefore, the combination of these two algorithms is capable of producing good scheduling and the clashing rate of a schedule can be handled. © Published under licence by IOP Publishing Ltd.

    Designing Payroll Information System: Case Study on CV. Bandung ID card

    Author: Soegoto Y.

    DOI: 10.1088/1757-899X/662/2/022125

    Abstract

    This study aims to build an information system that will help the business processes of an organization or a company that has implemented payroll and presence but the presence process is still using a lot of manual processes and has not been integrated with payroll. The methods used in this study are the object-oriented system approach method and the prototype system development method. Object-oriented approach is a new way of thinking seeing problems through real-world observations where each object is a single entity that has a combination of certain data structures and functions. The results of this study are the design and construction of a desktop-based payroll information system can more efficiently time and errors that often occur and processes that are still manually changed to be computerized for example in the presence process using RFID, recording and input data attendance is already automated finance payroll. © Published under licence by IOP Publishing Ltd.

  • Information System for Asset Management

    Information System for Asset Management

    Author: Fauzan R. ; Pamungkas V.Y. ; Wibawa J.C.

    DOI: 10.1088/1757-899X/662/2/022020

    Abstract

    The purpose of this study is to design an asset management information system in the form of desktop-based application design so that it can be used as a reference in implementing it into the application. With the application, it can facilitate BMN in making reporting related to assets control and management. Universities cannot be separated from the existence of assets owned, by seeing so many assets and development opportunities, there are often mistakes in planning, procurement, and inventory of data relating to assets. Sekolah Tinggi Pariwisata National Hotel Institute (NHI) Bandung is a College that organizes professional education programs in the field of tourism. In implementing its business processes, STP involves supporting assets owned by the State managed by the State Property section (BMN). In managing assets, which include the process of registration, request, acceptance, and maintenance of BMN goods still use the written recording process in the paper, as well as the process of making reports still using Microsoft Excel applications taken from the data written on the paper. From these problems, BMN requires a computerized information system design. System analysis methods uses Object Oriented Analysis and Design (OOAD), and Unified Modelling Language (UML). © Published under licence by IOP Publishing Ltd.
