Abstract

This paper estimated and forecasted the volatility of USD/IDR exchange rate using Constant Conditional Multivariate GARCH (Generalized Autoregressive Conditional Heteroskedasticity) and ARIMA (Autoregressive Moving Average) as the methods. The objective of this study is to comprehend and to execute a projection of the currency of Indonesia and Philippines while understanding the rapid movement of the variables (volatilility). The variables used are USD/IDR, Jakarta Stock Exchange Composite Index (JCI), World Oil Price, and Nominal Broad U.S. Dollar Index. The data was daily, taken from World Bank, Federal Reserve Economic Data, and Indonesian Stock Exchange during 2006-2025. The result showed that there was short term autoregressive moving average dynamics in USD/IDR return, through Mean Equation. The GARCH model showed high persistence of volatility and the shocks showed indication of long-lasting in term of duration. Persistent volatility implied that USD/IDR was sensitive to external shocks. The result also confirmed that the volatility is time-varying, meaning the fluctuations tend to cluster into specific downturn or upturn movement. The method used in this study did not consider about different period in volatility (leverage effect) as it used symmetric volatility as assumption.

Abstract

Deforestasi lahan merupakan salah satu kondisi krusial yang terjadi di Indonesia sebagai salah satu negara dengan megabiodiversitas di dunia. Upaya konservasi hutan melalui pembibitan pohon pada lahan gersang menjadi salah satu strategi keberlanjutan ekologi di area Malang, khususnya di hutan P-Wec Petungsewu, Kecamatan Dau Kabupaten Malang. Program pengabdian ini menerapkan Circular Bioeconomy Framework (CBF) untuk mengubah aktivitas pembibitan dan penanaman pohon menjadi sistem ekonomi sirkular yang menghubungkan konservasi in-situ dan ex-situ dengan penciptaan nilai ekonomi. Keterkaitan dengan SDGs 15 Life on Land ditegaskan melalui pengabdian konservasi hutan ini melalui upaya pelestarian spesies endemik wilayah Malang dan Indonesia yang memiliki nilai ekologis dan ekonomi keberlanjutan tinggi. Hasil pengabdian adalah terwujudnya sistem bioekonomi sirkular dengan indikator input lokal (melalui media tanam, benih, dan tenaga pada aktivitas pembibitan) serta zero-waste system di area Hutan P-Wec  melalui daur ulang limbah organic berupa pupuk kompos hasil limbah daun pohon. Hal ini terbukti dapat meningkatkan porositas dan aerasi tanah, sehingga dapat meningkatkan efektifitas pertumbuhan bibit pada lahan. Hasil berupa 17 jenis spesies bibit pohon yang sudah ditanam dan 5kg pupuk kompos dan 5kg sekam yang telah diolah dari limbah organik hutan P-Wec
