In this era of Industry 4.0, technology is advancing rapidly, and various applications are emerging to help traders optimize their product procurement. One such application is the forecasting or prediction system. Serba Serbi Online Shop Tanjungpinang is a shop that requires this system to manage its inventory successfully. As the shop offers a wide variety of goods, managing inventory has become challenging. The capital spent on inventory has increased, and unsold goods are piling up in the warehouse. To overcome this issue, the shop needs to calculate the amount of inventory required to reduce the stock build-up in the warehouse. The prediction method used for this purpose is the least square method. This method uses periodic or time-series data, which requires past sales data to predict future sales. Historical sales data is necessary to develop an inventory prediction system. The sales data for a single item from July 2022 to May 2023 was analyzed using the Least Square method. Based on this analysis, the predicted sales for June is 144.64, rounded to 145. The accuracy of the prediction results were tested, and the best accuracy was obtained from the prediction using 3 months of data, with an error rate of 5.47%. The prediction with the highest error rate was obtained from using 9 months of data, with an error rate of 10.65%. On average, the prediction accuracy is 0.02154%, which is considered very good.

Weather conditions are important to know because they have an impact on various human activities, such as agriculture, infrastructure, hydrology, and more. Several factors affect the weather, including wind speed, temperature, and air humidity. However, in this study, a mini weather station was designed to provide information not only on wind speed, temperature, and humidity but also on solar radiation. The research employed several sensors, including the DHT11, anemometer, and pyranometer. The research results indicate that the DHT11 error indoors is 1.4%, but it increases to 9% outdoors. The pyranometer shows a 3.62% error from direct solar radiation measurements. However, the wind speed sensor is still unstable, suggesting the need for improvement in future research.

The objective of this study is to develop an audit strategy for information system security at XYZ General Hospital, perform a comprehensive security assessment of the REMPEYEK (Electronic Service Medical Record) information system, and provide recommendations for improvement. Quantitative research is a methodology that involves the collection of data through direct assessment of the individuals or entities under investigation. In addition, the COBIT 5 tool is employed to analyze the gathered data in order to acquire a quantitative capability analysis. This study examines the COBIT 5 framework's relevance to the identification of business objectives for information system security in the context of the Rempeyek information system. The identified problems and obstacles in the system include inadequate budget management, insufficient coordination between Diklitbang and the units involved in application development, and a misalignment between information technology systems and security measures. The findings of the assessment on the maturity of the information system security indicate that the DSS05 and APO13 domains have achieved a level 2 status, known as "Managed Process." The capability values for these domains are recorded as 2.02 and 2.68, respectively. This suggests that the relevant procedures have been effectively executed, supervised, and regulated.

Stepper motors are one of the motor variants that are widely used in the manufacturing sector. Stepper motors have the characteristic of being able to be controlled both speed and position control in an open loop control system. The method used to control the rotation of the stepper motor is to send a series of electrical pulses with a configuration of frequency values and number of electrical pulses so that the stepper motor can control the rotational speed and angular position of the motor. Acceleration-deceleration control applies a method of gradually changing the frequency of electrical pulses by increasing the frequency every 4mS until it reaches the target frequency value. By applying the acceleration-deceleration method, the stepper motor is capable of rotating at a speed of up to 3000 rpm and the motor rotation angle position is from 10o-360o precisely, this acceleration-deceleration method can rotate the motor at a controlled speed of up to 3000 rpm.

Floods that hit areas that are supposed to be areas where flooding is impossible are often caused by garbage stuck in the ditches. As one of the causes of flooding in big cities such as Batam, so it is necessary to installtion a machine to collect waste bottles and other waste in the ditches to remove the waste and bottles that are in the ditches. The utilisation of a DC motor driven machine used in cars as a wiper drive can be used and controlled to drive a garbage collector which is relatively not too heavy on the load. DC motor rotation is forwarded to the engine drive wheel using a chain. The system for lifting garbage from the gutter to the storage tanks uses a chain that has been modified into a conveyor. The use of a conveyor slot which can be adjusted from 30cm to 60 cm wide by manually shifting the wheel base is necessary to overcome the width of the gutter which sometimes varies in width. The Motor DC result shall capable of moving forward or reverse, so the machine should move forward or backward the ditch with a speed of 0.0704 – 0.0759 m/s with a success rate of lifting 75.94% waste and is capable of transporting a maximum of 3 rotational waste bottles.
