There are several variables that are thought to have an effect on GRDP, namely foreign investment, government spending, the labor force participation rate, and the human development index. This study conducts modeling to obtain factors that influence GRDP in Indonesia. This study involves spatial effects using the SAR and SEM models. The results show that the SAR fixed effect model is the best model.</em></p> 2023-03-30T00:00:00+00:00 Copyright (c) 2023 Muhammad Azis Suprayogi http://journal.iteba.ac.id/index.php/jurnalsintak/article/view/79 PERSEPSI MASYARAKAT KOTA BATAM TERHADAP KETERSEDIAAN LAPANGAN PEKERJAAN DI KOTA INDUSTRI 2023-03-28T02:30:44+00:00 Bulan Purnama Utami 2124012@student.iteba.ac.id Nabila Azzahra 22124014@student.iteba.ac.id Vitri Aprilla Handayani vitri@iteba.ac.id <p>Penelitian ini dilakukan dengan tujuan untuk mengetahui persepsi masyarakat Kota Batam terhadap ketersediaan lapangan pekerjaan di kota industri. Penelitian ini menggunakan teknik penarikan sampel cluster sampling one stage yang menunjukkan Kelurahan Tanjung Pinggir di wilayah Kecamatan Sekupang sebagai lokasi untuk survei. Adapun sampel yang digunakan dalam penelitian ini adalah masyarakat yang berusia angkatan kerja di wilayah Kelurahan Tanjung Pinggir. Data yang digunakan dalam peneltian ini ialah data primer dengan menggunakan analisis kualitatif dan kuantitatif. Hasil yang diperoleh, lapangan pekerjaan yang ada belum sesuai dengan kebutuhan masyarakat sehingga belum mampu menekan nilai penggangguran.</p> 2023-03-30T00:00:00+00:00 Copyright (c) 2023 Bulan Purnama Utami http://journal.iteba.ac.id/index.php/jurnalsintak/article/view/80 EFEKTIFITAS PEMBELAJARAN DENGAN SISTEM BLOK 2023-03-28T01:52:02+00:00 Phila Angelina 2124001@student.iteba.ac.id Rani Gusrita 2124022@student.iteba.ac.id Tiama Tinggal Turinah 2124005@student.iteba.ac.id Vitri Aprilla Handayani vitri@iteba.ac.id <p>Efektifitas pembelajaran merupakan salah satu komponen yang banyak menjadi sorotan.

The method used to use forecasting techniques is ARIMA (Autoregressive Integrated Moving Average). ARIMA is also often called the Jenkins time series method. The data used is secondary data obtained from the Central Statistics Agency, namely year-to-year inflation data for 2017-2020. The results obtained from the 10 time series models used in forecasting the infallible value of the city of Batam for 2017-2020 are ARIMA (2,2,1) which has the smallest MS value of 0.05708 so it is used in forecasting, as well as an increase in inflation</em></p> 2023-03-30T00:00:00+00:00 Copyright (c) 2023 A'rsyil Majiid http://journal.iteba.ac.id/index.php/jurnalsintak/article/view/82 PENGARUH HARGA, PELAYANAN DAN KELENGKAPAN OBAT TERHADAP KEPUTUSAN PEMBELI APOTEK 2023-03-28T06:30:52+00:00 Risa Mustika Risamustika2603@gmail.com Andini Setyo Anggraeni andini@iteba.ac.id <p><em>The existence of pharmacies as health services and pharmaceuticals has an important role in the development of the current health sector, especially in the pandemic era. A good analysis of the pharmacy business is needed to find strategies that can be implemented to develop the business. One analysis that can be done is to analyze the factors that influence purchasing decisions. The factors to be analyzed are price, service and completeness. Data will be analyzed using multiple linear regression analysis. Based on the results of the analysis and discussion, it can be concluded that price has a negative effect on buyer decisions at Endar Farma Pharmacy with a drug price regression coefficient of 0.178; The service and completeness of the drug has a positive influence on the buyer's decision at Endar Farma Pharmacy, with a service regression coefficient value of 0.326 and a regression coefficient value of drug completeness of 0.401. The three variables above are very influential on the decision of Endar Farma Pharmacy buyers, this can be seen from the percentage obtained from these 3 variables of 54.3%.</em></p> 2023-03-30T00:00:00+00:00 Copyright (c) 2023 Risa Mustika http://journal.iteba.ac.id/index.php/jurnalsintak/article/view/83 FORECASTING PENGERJAAN BERKAS MENGGUNAKAN METODE ARIMA DAN SARIMA 2023-03-28T07:02:48+00:00 Paulina Octavia paulina3019@gmail.com Eko Sulistyono eko@iteba.ac.id <p><em>The National Land Agency (BPN) is a non-ministerial government agency in Indonesia which has the task of carrying out governmental tasks in the land sector in accordance with statutory provisions.

The Batam City National Land Agency always carries out administrative processes starting from Monday to Friday. However, currently the Batam City BPN is serving a "Weekend Service" so that it can facilitate services that cannot be served Monday to Friday. The aim of this research is to predict incoming files and work on them in January 2023. The steps taken are calling the model, then estimating the ARIMA model, then doing proof and forecasting. The results obtained are the number of files being worked on is increasing every day.</em></p> 2023-03-30T00:00:00+00:00 Copyright (c) 2023 Paulina Octavia
