Abstract

Tujuan dari riset ini adalah menganalisa sikap konsumen sepanjang pandemi covid-19 yang mempengaruhi pemakaian marketplace Tokopedia dengan Technology Acceptance Model (TAM). Riset ini melakukan survei mengolah informasi. Responden pada riset ini sebanyak 200 ibu rumah tangga di Kecamatan Jayamekar Kabupaten Bandung Barat, yang mengetahui serta pernah melakukan transaksi belanja online marketplace Tokopedia. Untuk menguji informasi Riset, peneliti memakai Partial Least Square (PLS) versi 3.2.3. Hasil riset menunjukkan kalau minat pemakaian marketplace Tokopedia pada saat transaksi online dipengaruhi oleh lima variable. Hal ini dilakukan untuk menjelaskan sikap para pengguna teknologi informasi padapemakaian aplikasi Tokopedia (actual use), kemudahan aplikasi Tokopedia (perceived easy of used), manfaat aplikasi Tokopedia (perceived usefulness), resiko aplikasi Tokopedia (perceived risk), kepercayaan para pengguna aplikasi Tokopedia (trust) yang memiliki pengaruh terhadap marketplace Tokopedia untuk pembelian online

Abstract

Big data plays an increasingly important role in education, offering great potential to improve educational decision making. Big Data collects, stores, and analyzes large amounts of and diverse data at very high speeds. In the educational context, big data collects data from various sources, including school management systems, student academic records, student satisfaction surveys, and online data. Analysis of this data can provide valuable information to decision makers in the education sector to identify relevant trends, patterns and opportunities. This research discusses the great benefits that can be gained from using Big Data in an educational context to support better decision making. Through research on the educational benefits of big data in supporting better decision making, it is hoped that this will provide an excellent opportunity to improve decision making in education. Through careful data analysis, education can become more effective, efficient and relevant to better meet the needs of students and society. The method used in this research is a quantitative method. Researchers conducted a survey using a Google form consisting of 15 statements related to the title of the research. Researchers found that using big data in education provides great opportunities to improve better educational decision making. And supported by careful selection as material for consideration. The limitation of this research is that the researcher only conducted research in schools and the researcher did not conduct research directly in schools but shared a survey link on a Google form containing a statement about the benefits of big data in supporting better educational decision making.

Abstract

Predicted the demand for 3 kilograms of LPG gas in different provinces of Indonesia is crucial for assuring the provision of energy to households. By employing the Exponential Triple Smoothing (ETS) technique, this study examines demand-influencing factors and consumption patterns. By integrating historical data's levels, trends, and seasonality, ETS enables accurate and timely forecasts. The findings illustrate the predicted outcomes for the ten provinces in Indonesia that have the highest demand for 3 kilograms of LPG gas, as well as the ten provinces that have the lowest demand across all regions. All provinces' MAPE forecasting error testing results utilizing the ETS method are incorporated with an exceptionally high degree of precision, given that the error rate is 5.27%.

Abstract

Indonesia, an archipelagic country located along the equator, is highly vulnerable to natural disasters. At the same time, its geographical conditions require reliable telecommunications to strengthen connectivity across its many islands. One effective solution is the utilization of High-Frequency (HF) communication technology, which enables long-distance communication and supports broadcasting-based telecommunications. This approach can expand available frequency channels, making HF radio communication an important tool for disaster-prone regions like Indonesia. To optimize HF communication, researchers have developed various models of HF channel radio systems, often represented statistically and implemented through channel simulators. Among these approaches, the Auto Regressive Integrated Moving Average (ARIMA) model has been identified as particularly suitable. This is because ARIMA can handle the non-stationary characteristics of time-series data, such as those found in HF channel attenuation measurements. In the modeling process, several ARIMA configurations were tested, including ARIMA (0,1,1), (0,0,5), (1,0,0), (1,0,1), (1,0,2), and (0,0,4). From these options, two models—ARIMA (1,0,0) and ARIMA (1,0,2)—showed the closest fit to the observed data. The final selection was made using the Akaike Information Criterion (AIC), where the ARIMA (1,0,2) model emerged as the best. This model provides the most accurate representation for predicting HF channel attenuation, supporting more reliable telecommunications systems for Indonesia.

Abstract

People-based cooperatives encounter digital hurdles to providing effective services. Wiguna Mertha Cooperative needs IT audits to ensure good operations, security, and corporate goals. Enterprise information technology audits are conducted using qualitative and quantitative methodologies in this research. IT audit goal mapping helps firms align business goals with corporate goals, vision, purpose, and IT procedures. PEG aligns IT investments and activities with company strategy, evaluates IT maturity, and prioritizes improvements. Interviews, questionnaires, observations, and documentation were used to analyze 5 cooperative employees' responses. Objective mapping for five corporate goals and maturity level analysis for four COBIT domains: EDM, APO, BAI, and DSS. The results revealed good maturity, with EDM averaging 3.85, APO 3.87, BAI 3.88, and DSS 3.53. Risk management, business resource optimization, IT data up keep, and IT service availability and capacity management are recommended improvements.
