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.

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.
黄金是一种贵金属，因其在投资和珠宝等各个领域的价值而闻名，通常被视为投资组合中的安全资产。然而，受经济、地缘政治和全球金融因素的影响，黄金价格波动很大。以往的研究主要集中在预测金价走势的方法上。近年来，经济变化和 Covid-19 大流行病等全球因素加剧了金价的复杂性和不确定性，凸显了准确预测金价的紧迫性。本研究利用统计和概率方法，全面分析和比较了自回归综合移动平均法（ARIMA）和普通最小二乘法（OLS）在预测金价方面的表现。自回归整合移动平均法擅长处理时间序列数据、识别复杂模式以及根据历史趋势预测价格变化。相反，OLS 作为一种概率方法，在根据金价数据调整线性模型方面表现突出，能提供对影响因素的详细见解。研究采用了 5 年黄金价格数据集（2018-2023 年），并使用平均平方误差（MSE）和平均绝对百分比误差（MAPE）评估了模型的性能。结果表明，OLS 优于 ARIMA，MSE（45.79 vs. 284.83）和 MAPE（0.0026 vs. 0.0066）更低。这项研究为市场参与者、投资者和研究人员理解商品市场行为，尤其是黄金市场行为提供了细致入微的见解，强调了准确预测方法在战略决策中的重要性。

The research aims to evaluate the capacity of Amazon Web Service's (AWS) Elastic Cloud Compute (EC2) Free Tier Web Server using the JMeter testing tool. The objective is to ascertain the extent of the server's load-bearing capabilities. Tests were conducted, loading 500 users within a 10-second range and 1000 users within a 1-second range. Despite being a free service, test results showed the server's capability to handle high loads without errors (0% error rate). These findings illustrate the free service's ability to maintain stable performance under significant user loads. The utilization of EC2 Free Tier on AWS demonstrates its capacity to handle heavy tasks without compromising service quality. From about 5 steps in each of two tests, the value for sample time / response time in the initial test of the Amazon Web Service Web server is 59 / ms (millisecond) and the average latency value in the second test, namely 7.213 /ms (millisecond). Both of these gained CPU Utilization from minum, average and maximum with final rate are zero Error. This outcome concludes that the free server possesses robust and reliable capabilities, instilling confidence in an effective and efficient server solution even under high usage levels without additional costs.

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.

Technological developments in the field of agriculture are now expanding widely, various modern tools must be owned to assist farmers in cultivating plants. The owners of the chili plants do watering and fertilizing by collecting water or fertilizer and then giving it to the plants one by one. This is not a problem if the plant owner has free time. However, if the plant owner is busy with other things or is having business that makes the plant owner unable to care for the plant, then this becomes a problem because when the plant does not receive sufficient care, the plant will easily wither and die. Seeing the existing problems, this research will design a system that can automatically water and fertilize plants based on IoT with monitoring from an Android application. The design of this system uses an Arduino microcontroller as a controller, the nodeMCU esp2688 wifi module to send data from the sensor to the web server, a soil moisture sensor to determine soil moisture, a real time clock (RTC) for fertilization scheduling and a relay as an automatic switch on the water pump. This system aims to help the activities of farmers who still use physical force to water and fertilize plants. The IoT-based automatic watering and fertilizing system uses the prototype development method, namely by collecting system requirements, building prototyping, evaluating prototyping, coding the system, testing the system, evaluating the system and using the system

The Akhlaqu Application is a web-based Islamic learning platform used by Al-Falah Integrated Islamic Elementary School to facilitate the recording and reporting of students’ activities in developing their memorization. This research aims to assess the level of user satisfaction with the Akhlaqu Application using the System Usability Scale (SUS). The results showed a high level of usability, measured by a System Usability Scale (SUS) score of 89.7, indicating a “very good” quality application that meets high usability standards. In addition, the implementation of text indexes on MongoDB has a positive impact on the speed of transaction data search, especially on complex data searches, improving the efficiency and responsiveness of the application. The implications of this research involve recommendations to continue to improve the usability and performance of the Akhlaqu Application, by maintaining the use of MongoDB index techniques as a reliable solution for optimizing the database. The study concludes that the Akhlaqu Application is an effective tool for managing students’ memorization and recommends further improvements to enhance its usability and performance.
