Abstract

This research aims to develop a chili logistics system that utilizes the Internet of Things (IoT) and blockchain technology. This system is designed to improve the efficiency and transparency of the chili logistics process from collection, delivery, to distribution using a smartphone. IoT is used to monitor environmental conditions for storing and transporting chilies, such as temperature and humidity, so as to prevent damage to chilies. Meanwhile, blockchain technology is used to optimize transparency and security in the chili logistics process by ensuring the authenticity of products and data recorded on the blockchain. The methodology used in this study uses the prototyping method. Implementation of IoT technology with an average temperature of 30 ֯ C and 40% humidity. Also, the blockchain system in the chili logistics system can be an effective solution in increasing efficiency, transparency and security in sending chilies.

Abstract

When making investments, investors definitely want high returns with low risk. However, high returns are usually accompanied by high risks and vice versa. Value at Risk (VaR) and other measurement tools help manage risk. VaR measures possible losses. However, VaR has weaknesses, thus Tail Value at Risk (TVaR) can be used to evaluate the likelihood of larger losses than VaR. Copula can be used in risk management because it does not require normal distribution assumptions so it is well applied to financial data. The purpose of this research is to use the Ali-Mikhail-Haq copula to estimate TVaR value of blue chip stock portfolios, including those of BRI, BCA, and Bank Mandiri. Data used is the closing price of daily stocks for the period Jan 1 2021 to Jun 30 2023. The results of calculating TVaR value at the 90%, 95%, and 99% confidence level of the combination of BMRI and BBRI stocks are 0,0574; 0,0668; dan 0,0807. At a confidence level of 90%, 95% and 99% TVaR value of the combination of BMRI and BBCA stocks is 0,0569; 0,0669; dan 0,0886. The combination of BBRI and BBCA stocks resulted in TVaR at 90%, 95% and 99% confidence levels are 0,0238; 0,0283; 0,0376.

Abstract

Penelitian dilakukan dengan tujuan untuk mendapatkan pemodelan ARCH/GACRH untuk volatilitas saham PT Destinasi Tirta Nusantara Tbk serta menganalisis pengaruh variabel makroeonomi yaitu, nilai tukar, suku bunga, inflasi, indeks harga konsumen, dan jumlah uang beredar terhadap volatilitas saham PT Destinasi Tirta Nusantara Tbk. Metode analisis digunakan dalam penelitian adalah menggunakan model ekonometrik ARCH/GARCH. Dari hasil pengujian, model terbaik adalah ARCH (1,0) dan model tersebut dapat digunakan untuk menjelaskan pengaruh nilai tukar, suku bunga, inflasi, indeks harga konsumen, dan jumlah uang beredar terhadap volatilitas saham PT Destinasi Tirta Nusantara Tbk. Model ARCH (1,0) sebagai model terbaik karena memenuhi kriteria, yaitu semua konstanta dan koefisien pada model signifikan, memiliki nilai adjusted R-squared yang paling tinggi, dan melihat nilai koefisien AIC (Akaike Info Criterion) dan SIC (Schwarz Info Criterion) yang paling rendah. Hasil pengujian menunjukkan nilai tukar dollar terhadap rupiah (USD/IDR), inflasi, dan jumlah uang beredar berpengaruh secara negatif dan signifikan sedangkan suku bunga dan indeks harga konsumen berpengaruh positif dan signifikan terhadap volatilitas pada indeks saham pertambangan di Indonesia. Koefisien determinasi (nilai adjusted R-squared) sebesar 0,92. Hal ini berarti 92% variasi volatilitas pada saham PT Destinasi Tirta Nusantara Tbk dapat dijelaskan oleh variasi dari empat variabel makroekonomi, yaitu nilai tukar, suku bunga, inflasi, indeks harga konsumen, dan jumlah uang beredar sedangkan sisanya (8%) dijelaskan oleh sebab-sebab lain di luar penelitian. Selain itu, berdasarkan koefisien ARCH/GARCH ditemukan bahwa saham PT Destinasi Tirta Nusantara Tbk dipengaruhi volatilitas saham saat ini dan periode lalu. Volatilitas pada saham PT Destinasi Tirta Nusantara Tbk adalah persistent volatile yaitu volatilitas yang tinggi dan terjadi terus-menerus.
