Abstract

Forecasting is an activity to get an estimate of the value that will appear in the future by paying attention to past events. Forecasting can be used as decision support in determining a policy in various fields. Forecasting can be done using statistical methods such as regression analysis, trend analysis, MA, and ARIMA. In this paper, the fuzzy time series markov chain method will be forecast which will be applied to rice production data in D.I. Yogyakarta Province. The fuzzy time series markov chain method was chosen because it does not need to meet certain assumptions so that the fuzzy time series markov chain can be applied to time series data with stationary and non-stationary patterns. This study aims to analyze fuzzy time series markov chain for rice production forecasting. This study uses time series analysis. The data used in this research is secondary data. The data used in this study is data on rice production in D.I. Yogyakarta Province in 1970-2017 taken from the website www.pertanian.go.id. Historical data consists of 48 data. Solving this research problem using fuzzy time series markov chain method. The results of the study show that forecasting with 11 fuzzy sets is declared the best forecast with a mean absolute percentage error of 4.156%. .

Abstract

Yogyakarta  merupakan salah satu wilayah di indonesia yang  indah  dan  sarat akan nilai sejarah, selain itu Yogyakarta  juga  dikenal  sebagai  pusat  budaya  dan  pariwisata  di  Pulau  Jawa.  Hal  tersebut  menjadi  daya  tarik tersendiri  bagi  wisatawan  untuk  memilih  Yogyakarta  sebagai  tujuan  wisata  mereka.  Setiap  wisatawan  memiliki kriteria tersendiri dalam memilih tujuan wisata ditengah banyaknya obyek wisata yang ada di Yogyakarta, sehingga diperlukan  suatu  aplikasi  yang  dapat  membantu  wisatawan  dalam  memilih  tujuan  wisata  yang  sesuai  dengan kriteria.  Adapun  tujuan  dari  perancangan  aplikasi  fuzzy  decision  making  ini  adalah  membantu  wisatawan  dalam memilih  alternatif  wisata  di  Yogyakarta  yang  sesuai  dengan  kriteria  yang  diinginkan  wisatawan.  Kriteria  yang ditentukan  oleh  wisatawan  adalah  jenis  wisata,  biaya,  pemandangan/isi  museum,  keamanan,  transportasi, kebersihan,  keramaian,  dan  fasilitas.    Aplikasi  ini  menggunakan  Metode  Tahani  dalam  proses  pemilihan  tujuan wisata dengan operator AND. Aplikasi fuzzy decision making kemudian diimplementasikan dengan Graphical User Interface  (GUI)  agar  tampilan  aplikasi lebih  komunikatif terhadap  pengguna.  Tingkat  keakurasian  aplikasi  fuzzy decision making  pada uji kesesuaian obyek wisata dengan menggunakan operator AND pergandaan sebesar 75%, sedangkan  untuk  keakurasian  menggunakan  operator  AND  minimum  sebesar  93,33%.  Jadi  operator  yang digunakan selanjutnya untuk aplikasi ini adalah operator AND minimum.Kata kunci: fuzzy decision making, Graphical User Interface (GUI), obyek wisata, Metode Tahani.

Abstract

Indonesia is a nation that prepares its human resources to face the times. Many preparatory efforts have been made, one of which is the numeracy literacy movement since 2016. As a form of support for the numeracy literacy movement, this community service aims to improve the numeracy literacy skills of students through Himatika Mengajar activities. The participants are MA As Salafiyah Mlangi students who are also santris from several Islamic boarding schools in the Mlangi area, Sleman. The method used in this service is the habituation of numeracy literacy-based questions. The result of this service is that santris become familiar with numeracy literacy-based problems and provide insight for santris to apply numeracy literacy skills in everyday life.
