Abstract

Ekonomi merupakan salah satu faktor yang terpenting untuk mengindikasi suatu negara kuat atau tidak. Khususnya ekonomi makro akan mempengaruhi operasi perusahaan setiap saat. Variabel-variabel dalam ekonomi makro diantaranya suku bunga, kurs nilai uang, dan IHSG (Indeks Harga Saham Gabungan). alam penelitian ini dianalisis mengenai hubungan variable-variabel ekonomi makro yaitu suku bunga, kurs nilai uang dan Indeks harga saham gabungan (IHSG). Data yang digunakan adalah data sekunder yang sudah tersedia di website Bank Indonesia, OJK dan Bursa Efek Indonesia (BEI). Beberapa penelitian terdahulu telah dilakukan untuk melihat keterkaitan dan pengaruh variable-variabel tersebut dengan regresi linear berganda. Dalam penelitian ini, teknik analisis yang digunakan adalah “path analisis” dan data yang digunakan pada tahun yang berbeda yaitu tahun 2007 sampai dengan 2015. Dari Hasil penelitian ini diperoleh korelasi antara tingkat suku bunga dan kurs nilai rupiah terhadap USD, korelasi tingkat suku bunga terhadap IHSG sebesar 80,11%, korelasi kurs nilai rupiah terhadap IHSG sebesar 0,029%; sedangkan korelasi tingkat suku bunga dan kurs nilai rupiah secara simultan terhadap IHSG sebesar 80,1%. Dan model matematika hubungan antara tingkat suku bunga dan kurs nilai uang terhadap IHSG adalah Y = -0.06 X1 + -0.895 X2 + ε.

Abstract

The rapid development of technology aligns with the development of the internet, which keeps growing on a daily bases, resulting in the proliferation of internet service providers today. This is due to the high public demand for internet access, which has turned it into a "primary" need and a separate lifestyle, especially for people in the Bandung Raya area. Consumer brand switching behavior cannot be avoided in the face of increasing competition for internet service providers. One of the companies in Indonesia that provides internet provider services is PT Telkom Indonesia with IndiHome products. The purpose of this study is to identify the factors that cause brand switching behaviour between IndiHome customers in the Bandung Raya area and to know which has the highest and lowest dimension contribution based on the factors that cause brand switching behaviour. This study's population consists of customers who have switched from IndiHome products to other products and live in the Bandung Raya area. The sampling technique used is non-probability sampling, specifically the purposive method (according with goal of this study) by distributing questionnaires to customers who have switched from IndiHome to other internet service providers. The data in this study was analyzed quantitatively using a descriptive analysis method. Based on the results of the research through 101 respondents, they "agree" that the factors of pricing, inconvenience, competitor attractiveness, and failure of core services contribute to brand switching behaviour. The highest contribution to brand switching behaviour is the dimension of core service failures, while the lowest contribution is the dimension of inconvenience.
