Abstract

Regional economic growth is influenced by various factors that need to be analyzed accurately to support the formulation of effective policies. This study aims to analyze the influence of economic factors on the Gross Regional Domestic Product (GRDP) in North Sumatra Province. The main issue raised is the need for an appropriate model to understand the relationship between economic variables and GRDP. This study uses panel data from 33 districts/cities during the period 2019–2023 obtained from official sources. Through Chow, Hausman, and Lagrange Multiplier tests, the Fixed Effect model was selected. The results indicate that population size, number of poor people, and Human Development Index (HDI) significantly influence RDP.

Abstract

Inflation is an important issue that affects the economic stability of a country or region. Unstable inflation will have a negative impact on society, especially on commodity prices including food and energy. Inflation is classified as a time series and will usually recur over time, five years later, or ten years later. , the problem of inflation needs to be studied and analyzed using existing approaches in time series. This research focuses on the application of Hybrid ARIMA-Adaptive Neuro Fuzzy Inference System method for inflation estimation, which is expected to provide a more accurate picture of the price fluctuations of basic needs in North Sumatra. Overall, the results show that the ability of the Hybrid ARIMA-Adaptive Neuro Fuzzy Inference System method in estimating inflation values is quite good with the results tending to be stable and not experiencing many sharp fluctuations. The inflation value is in the range of around -2.69 to -2.73 throughout the predicted period. However, a continuous negative number indicates a price decline or economic pressure, so further analysis or development is needed to understand the cause. The estimation results may help to maintain stability or make desired changes in the future.

Abstract

In a Government Agency, office stationery supplies are an absolute necessity. The provision of adequate office stationery will facilitate performance. This study aims to predict the demand for office stationery using Monte Carlo Simulation. Monte Carlo is a numerical analysis method that uses random number samples. The data used in this study are primary data in the form of the number of stock items and the number of requests for goods from January to December 2023. The accuracy result using the Monte Carlo method for Year 2024 is 91.78%. This shows that the Monte Carlo method simulation can be used to predict the demand for stationery for the following year.

Abstract

Vaksin merupakan sebuah racikan atau bahan yang digunakan untuk menstimulus antibodi agar bisa lebih kebal terhadap suatu penyakit. Penyakit ini disebabkan oleh gigitan hewan yang menderita rabies yang ditularkan pada manusia. Di Sumatera Utara pemberian vaksin rabies ini diberikan kepada dinas perkebunan dan peternakan Dinas ini akan mendapatkan kiriman vaksin rabies dari pemerintah pusat di Jakarta. Dikarenakan padatnya pekerjakan membuat bidang tersebut harus menghemat waktu agar semua pekerjaan dapat dilakukan dengan baik. Model Backward Recursive Equation merupakan salah satu model yang ada di dynamic programming. Program Dinamis (dynamic programming) merupakan metode pemecahan masalah dengan cara menguraikan solusi menjadi sekumpulan (stage). Dinas Ketahanan Pangan dan Peternakan ? Nasional Sport ? Kopi Wae Medan ? Simpang Raya Sakumoring Setia Budi ? Universitas Quality ? JNT Express Simpang Pos ? Dinas Perkebunan dan Peternakan Pemerintah Provinsi Sumatera Utara Dengan jarak 13,3 km.
