Abstract

The home automation system, or commonly known as smart home system, is increasingly being utilized due to its ability to provide comfort and convenience to homeowners in monitoring and controlling household appliances remotely and automatically. The implementation of home automation is expected to aid in electricity energy savings. The aim of this research is to monitor household electricity usage in real-time based on a web server. The method used consists of four stages: 1) selection of software and hardware, 2) system design, 3) program development, and 4) testing. The test results of monitoring household electricity usage for three days show that the cost to be paid for electricity consumption after three days of usage with a tariff corresponding to the installed power (1300 VA) is 26,293 Rupiah.

Abstract

The exchange rate between two countries is the price of the currency used by residents of these countries to trade with each other, the relationship between the Rupiah exchange rate and the Yuan is one of the important aspects in the dynamics of international trade. Therefore, forecasting the exchange rate is important as an effort to predict the exchange rate of Rupiah against Yuan in the future. The method used for forecasting is Singular Spectrum Analysis, namely decomposition and reconstruction. The accuracy of the resulting forecast is measured using the Mean Absolute Percentage Error criterion. The exploration results obtained are forecasting accuracy based on the Mean Absolute Percentage Error value of 2.15% with a window length of 23 which identifies that the forecasting results are accurate and effective. Forecasting is said to be accurate if the Mean Absolute Percentage Error value is lower than 10% and close to 10%

Abstract

The purposes of this research are to know, describe, and analyze institutional repository softwares selection in Universitas Brawijaya (UB) Library, State University of Malang (UM) Library, and University of Muhammadiyah Malang (UMM) Library, also comparing software features of institutional repository.This research is using multi-site case study method with qualitative approach. Data was collected by observation, interviews, use of documents and audio-visual material. The results of this research indicate that the selection of software in academic library needs to pay attention to four aspects of software selection: (1) as needed; (2) have a licence; (3) technical support, training, relevant documentation and maintenance; (4) staff responsible for the selection and evaluation of digital collection software and related services to meet user or community needs. The selection of institutional repository software is not appropriate, resulting in the UB Library to migrate data from BKG to Eprints and UMM Library to migrate manually from GDL to Eprints. Academic library needs to pay attention to right aspects of software selection in building and developing institutional repositories and features.
