Abstract

The use of information systems is one of the IS/IT investments in a company. Information systems can certainly improve company performance, but many information systems have not been implemented optimally, and do not meet the company's vision, mission and goals. This research was conducted with the aim of making strategic planning for the implementation of the E-Commerce information system at PT. Beware of Digital Innovation. The strategic plan was developed based on the IT Balanced method. Data collection was carried out through interviews, then the data obtained was subjected to SWOT analysis, then mapped into the IT Balanced Scorecard. This research produces strategic recommendations that companies can implement, including: 1) from an operational excellence perspective, companies need to determine IS/IT employees and regular maintenance; 2) user orientation perspective, companies need to adjust the interface design according to customer wishes and provider manuals as a template for system use; 3) future orientation perspective, companies need to recruit employees which can be done with background checks; 4) from a business contribution perspective, companies need to maintain and improve service quality.

Abstract

Gold, a precious metal renowned for its value in various sectors, including investment and jewelry, is often considered a secure asset within investment portfolios. However, its prices exhibit high volatility influenced by economic, geopolitical, and global financial factors. Previous research has focused on predictive methods to anticipate gold price movements. In recent years, heightened complexity and uncertainty, exacerbated by global factors such as economic shifts and the Covid-19 pandemic, emphasizes the urgency of accurate gold price predictions. This study comprehensively analyzes and compares the performance of Autoregressive Integrated Moving Average (ARIMA) and Ordinary Least Squares (OLS) in forecasting gold prices, utilizing statistical and probabilistic approaches. ARIMA excels in handling time series data, identifying complex patterns, and forecasting price changes based on historical trends. Conversely, OLS, a probabilistic method, stands out in adjusting linear models to gold price data, providing detailed insights into influencing factors. The research employs a 5-year gold price dataset (2018-2023) and evaluates the models' performance using Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE). Results indicate OLS outperforms ARIMA, with lower MSE (45.79 vs. 284.83) and MAPE (0.0026 vs. 0.0066). This study contributes nuanced insights for market participants, investors, and researchers to comprehend commodity market behaviour, particularly in gold, emphasizing the importance of accurate prediction methods in strategic decision-making.

Abstract

The number of internet users in Indonesia has recently increased, currently reaching around 62.1% of the total population. The prevalence of social media use has provided benefits for many stakeholders to be involved in the socialization and promotion of their products and activities. Information regarding the latest government programs and activities is published through the official website of the West Nusa Tenggara Provincial Government and the official pages of each office within the West Nusa Tenggara Provincial Government. The potential of social media needs to be maximized in order to disseminate government programs and activities to the community. Social media offers governments the potential to increase democratic participation by encouraging the public to have a voice in policymaking, working with the public to improve services, gathering ideas, and increasing transparency. This research seeks to apply web scraping techniques to collect data with the aim of monitoring social media performance and identifying factors that are closely related to the level of response elicited by a social media post. The research results show that on average a post on the official page of the West Nusa Tenggara Provincial Government gets around 114.9 likes, 5.1 comments and 11.6 shares. Importantly, one of the important factors that influences the number of likes a post receives is the time it is published. Optimal publication times for the official pages of the West Nusa Tenggara Provincial Government are observed between 06.00-16.00 and 18.00-21.00. By looking closely at social media performance and identifying these influencing factors, social media managers are ready to gain invaluable insights to improve performance by precision and efficacy.

Abstract

The government has developed a population administration system to support public services, one of the media used by the government is electronic government (e-government). One of the villages that has a large Regional Revenue and Expenditure Budget (APBD) in the Serang district, Banten province is Ranjeng village, Ciruas sub-district. The problem is that data management in villages is still carried out semi-manually, there is no specific application to handle this management so it is not time efficient, reporting and the level of service to the community is less than optimal. To overcome these problems, a system is needed that can help the community in submitting letters and can help the village government to improve services to the community. The system design used in this research is using the Waterfall method so that it is easier to develop and using UML (Unified Modelling Language) for visual system modelling, while the programming language used is PHP using the Laravel framework. The final result of this research is a system that can improve the services of the Ranjeng Village Office to the community to be optimal.

Abstract

Mango, originating from India and bearing the scientific name Mangifera indica L, spread to Southeast Asia, including Malaysia and Indonesia. Rich in vitamins A and C, mango boosts immunity and exhibits a wide genetic diversity. From the genetic diversity and types of mango leaves, many people do not understand well about the types of mangoes based on mango leaves. Therefore it is necessary to identify the type of mango based on the leaves so that people can easily understand the type of a mango. The Convolutional Neural Network (CNN) method proves effective in identifying plants based on morphological features. CNN, a development from Multilayer Perceptron (MLP), is employed in testing using Teachable Machine with 60 mango leaf images, divided into 3 classes. Across 4 different classifications, the average confusion matrix shows CNN accuracy at 83.30%, precision at 94.43%, and recall at 88.28%. With CNN, the accuracy in identifying mango leaf characteristics improves.
