Abstract

Pandemi COVID-19 semakin mempercepat transisi ke layanan keuangan digital dan memperkuat kebutuhan untuk transaksi digital tanpa kontak dan tanpa uang tunai. Layanan keuangan digital dan financial technology telah memungkinkan transaksi digital pada masa pandemi, serta pembayaran dan transfer yang lebih cepat dan lebih aman. Namun demikian sebagian masyarakat Indonesia belum memiliki rekening bank sehingga tidak dapat menggunakan layanan bank. Masyarakat yang tinggal di pedesaan dinilai belum dapat memanfaatkan financial technology dengan optimal dan relatif kurang memiliki akses memadai ke layanan keuangan. Penggunaan pinjaman online di Indonesia, sebagai salah satu penggunaan financial technology, didominasi oleh pengguna pinjol perempuan. Mayoritas pengguna pinjaman online, khususnya perempuan, belum memahami besarnya resiko pinjaman online yang tidak memiliki izin. Oleh karena itu kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman para kader PKK mengenai financial technology dan meningkatkan pemahaman peserta mengenai daftar pinjaman online yang legal serta resiko yang diakibatkan pinjaman online yang ilegal. Adapun mitra dari kegiatan kepada masyarakat ini adalah kader PKK di Kampung Panyandaan Desa Jambudipa Kecamatan Cisarua Kabupaten Bandung Barat. Teknik pengumpulan datanya dilakukan dengan observasi, wawancara, dan dokumentasi. Dari kegiatan ini diharapkan dapat meningkatkan pemahaman kader PKK mengenai finansial teknologi, khususnya mengenai pinjaman online. Dengan peningkatan pemahaman yang telah diperoleh diharapkan para kader PKK dapat turut menyebarluaskan kepada masyarakat sekitar sehingga mereka dapat lebih memahami dan lebih berhati-hati terhadap pinjaman online ilegal.

Abstract

Composite index and exchange rate are important indicators that represent a country's economic performance, where there is a relationship between the two. In this study, the ideal model to capture the volatility of the composite index and exchange rate will be determined. to investigate the dynamic dependency relationship between the composite index and the exchange rate, first use a Vector Autoregressive (VAR) model. The best model in describing the volatility of the composite index is the EGARCH model while the exchange rate is using the TARCH model. According to research, there is an asymmetry relationship between the volatility of stock returns and the exchange rate, which means that the market will react to bad news more quickly than good news. According to the VAR model, the present volatility is influenced by the volatility of the prior period and there is a one-way causal relationship between the composite index and the exchange rate.

Abstract

The performance of stocks, as measured by stock return, is a crucial factor and often a primary consideration for investors when making investment decisions. The potential for profit in investing is attainable when investments are made for the long term and in the right instruments. The objective of this research is to analyze the influence of market capitalization growth, measured by the value of stock price and tradable shares, and leverage level, measured using the debt to equity ratio, on stock performance measured by stock returns. The research methodology employs descriptive verification analysis with a quantitative approach. The study focuses on the manufacturing industry, specifically the automotive and component sub-sector, listed on the Indonesian Stock Exchange (IDX). Observations were carried out over the period 2015-2020, involving 12 stock issuers. The sampling method utilized was purposive sampling. Data analysis was conducted using panel data regression, with the application of an F-test to examine the research model and a t-test to evaluate the research hypotheses at a significance level of 5% alpha. The results of the model test demonstrate a good fit, allowing for the subsequent testing of research hypotheses. The research findings reveal that market capitalization growth (market cap) has a positive and significant correlation with stock performance, as measured by stock returns. On the other hand, the leverage level measured using the debtto equity ratio has not impacted stock performance.
