Abstract

Climate change and the growing need for water resources have driven increased attention to the monitoring and management of rivers and other water sources. River water level is one of the important parameters in monitoring water quality and quantity, as well as in understanding the dynamics of river ecosystems. Therefore, the development of reliable, accurate, and high-technology-based water level measuring instruments is an urgent need. This research will create a system that can detect river water levels periodically using A01NYUB sensors. This water level data will be sent to a website using the internet network via GSM Modem. The results show that the A01NYUB sensor has a measurement error of 0.26% and a standard deviation of 0.43%. This proves that the A01NYUB sensor can be used for flood early warning systems because it has a measurement error and a fairly small standard deviation.

Abstract

A safe is designed to securely store valuable items, including important documents, jewelry, money, and other precious belongings. Modern safes often feature manual or semi-automatic locking systems, such as combination locks or cylinder locks. However, combination locks can be less secure and efficient, making them vulnerable to theft. In Indonesia, the adoption of RFID (Radio Frequency Identification) technology, especially in E-KTP cards, has seen progress, though its potential remains underutilized. This research integrates an advanced logic gate circuit using IC gates—AND, XOR, and NOT—functioning as a password mechanism. The device operates by requiring users to tap their E-KTP against a reader to unlock the safe door. Upon a successful tap, an LCD screen displays relevant information and requests a 16-bit binary password made up of 8 "1s" and 8 "0s." Users have 20 seconds to input the correct password; exceeding this time will reset the system, prompting another E-KTP tap. If an unregistered E-KTP is used, access is denied. The RFID reader, functioning at a frequency of 13.56 MHz, can read the E-KTP ID from a maximum distance of 1.3 cm. The integrated circuit logic will output HIGH only when the entered binary password matches the pre-set code within the safe, ensuring a secure and efficient locking mechanism for valuable items.

Abstract

The school library at SD Negeri Pabelan 2 Kartasura contains various kinds of book collections, such as books supporting teaching and learning activities or textbooks, encyclopedias, language dictionaries, and storybooks. The results of observations and interviews conducted by the author with one of the teachers of SDN Pabelan 2 Kartasura, found that the system running in the library of SDN Pabelan 2 Kartasura has not run optimally because it is still done manually, such as book loan transactions are still carried out by writing data related to borrowing into a transaction book which often causes problems in its management so that loss often occurs. This research aims to design a web-based library information system that is expected to be used for the library system at SDN Pabelan 2 Kartasura. The system development method used to design the library information system at SDN Pabelan 2 Kartasura is scrum. According to the points that have been interpreted the system built has a sufficient level of reliability with the score obtained is the average score, which is 68. The web-based library information system at SDN Pabelan 2 Kartasura was successfully developed and runs well.

Abstract

The advancement of technology has significantly impacted various fields, including agriculture. One application of technology in this sector is the detection of diseases in plants such as cacti, Sansevieria, and succulents. These ornamental plants are popular but susceptible to various diseases that are often difficult to distinguish visually. This research aims to design and develop an expert system for disease detection in cacti, Sansevieria, and succulents using the Dempster-Shafer method. The Dempster-Shafer method is applied in rule formulation, while a relational database model serves as the database structure. The system development follows the prototyping method, with data collected through literature reviews and interviews with domain experts. Testing on Soft Rot disease in cacti demonstrates the system's capability to calculate a certainty level of 0.9075 or 90.75%, indicating the effectiveness of the method in identifying diseases based on observed symptoms. This system is expected to provide significant assistance to farmers and plant enthusiasts in early disease detection, enabling prompt and appropriate treatments to maintain plant health.

Abstract

This study aims to predict the number of micro, small, and medium enterprises (MSMEs) in Bandung City using the ARIMA (AutoRegressive Integrated Moving Average) method. MSMEs play a crucial role in the local economy, particularly in creating jobs and driving economic growth. Predicting the number of MSMEs is important for understanding future trends to support better planning and policy-making. The data used in this study includes the number of MSMEs in Bandung City from 1990 to 2023. The ARIMA method was chosen for its ability to handle time series data with seasonal patterns and trends and for providing accurate predictions based on historical data. The ARIMA (2,1,0) prediction model was selected as the best model, with model evaluation results showing an MAE value of 666.9431 and a MAPE value of 7.55%. The accuracy of this study using the ARIMA (2,1,0) model is 92.45%. Based on the research findings, the AutoRegressive Integrated Moving Average (ARIMA) method can be used to predict the number of Micro, Small, and Medium Enterprises (MSMEs) in Bandung City.
