Attendance in the world of work is something that cannot be missed, because it is one of the performance assessments of an employee in the company as well as one of the indicators of determining performance every month. Therefore it is very important to record employee attendance correctly. CV Adi Bakti is one of the companies that still uses paper to record attendance. This causes employees to do things that are not expected, such as signing the wrong column or signing attendance for coworkers who are not present that day. In addition, attendance that is only in the form of sheets allows damage and loss and causes undocumented employee attendance reports every month. Seeing from this problem, the author designed an Android-based Attendance Information System using QR Code technology in order to provide convenience for companies in the attendance process and attendance reporting. This data collection uses observation, interview, and literature study methods. The system development method in this study uses the Prototype method. The results of this study are an Android-based Attendance Information System using QR Code technology that can assist companies in presenting employee attendance data accurately and quickly. Can make it easier for companies to make or recap employee attendance reports which are automatically printed on the system
工作中的考勤是不容忽视的，因为它是公司对员工的绩效评估之一，也是决定每月业绩的指标之一。因此，正确记录员工考勤非常重要。CV Adi Bakti 是仍在使用纸张记录考勤的公司之一。这就导致员工做出一些意料之外的事情，比如签错一栏或为当天不在的同事签考勤。此外，仅以纸张形式记录考勤会造成损坏和遗失，并导致每月的员工考勤报告无据可查。看到这一问题，作者利用二维码技术设计了基于安卓系统的考勤信息系统，以方便企业的考勤流程和考勤报告。本次数据收集采用了观察法、访谈法和文献研究法。本研究的系统开发方法采用原型法。本研究的成果是使用二维码技术的基于 Android 的考勤信息系统，该系统可帮助企业准确、快速地呈现员工考勤数据。可使企业更容易制作或复述员工考勤报告，并在系统上自动打印出来

Currently, the internet has become a basic need in the process of providing information and knowledge. Public, government and private services compete with each other in the use of information technology, which is expected to support employee performance and service. Therefore, human resources are needed who not only master material aspects, but also have adequate capacity and ability to apply and develop information in all fields. The use of this monitoring system is very necessary for the sidoarjo communicarions and information services departement and institutions that operate in the network sector and also have a fairly broad and complex customer coverage. Problems that often occur are slow internet connections, broken network cables, damaged network devices, etc. At that time, a network monitoring system was needed as a system that could detect when the network connection was lost. The research method used in this research is experimentation, namely a category of research that aims to find the cause and effect situation of a phenomenon. Therefore, this research is to investigate cause and effect, in accordance with previous conditions. From the results of the tests carried out, Mikrotik succeeded in sending notification messages in real time to the Telegram bot, with an average response time of 1 second in each condition. Router and Telegram will detect and send real-time message notifications to administrators if the internet connection status changes from off to active or vice versa

Length measurement is an activity to determine the length value of an object, surface, or other object. The measurement process generally requires conventional length measuring tools such as a ruler or ruler, tape measure, or calipers. Length measurements will experience problems when conditions do not allow the use of conventional measuring instruments due to position factors, the size of objects or surfaces that are too large and difficult for one person to reach, or differences in results obtained when measuring using non-standard units which cause uncertainty the measuring value. Augmented Reality is a technology that allows users to see the real world combined with virtual objects without changing the real world as the main environment. This technology also allows the length measurement process to be carried out using virtual objects as measurement markers and provides real-time measurement results without using conventional length measuring instruments. The results obtained are a length measurement application that can run by relying on virtual objects in the form of pointers which are placed as markers and connected by lines to obtain information in the form of the value of the measurement results. With an average accuracy level of 98.03%, this length measurement application can be used as an alternative medium for carrying out the length measurement process.

Risk management plays a crucial role in securing the sustainability and growth of Micro, Small, and Medium Enterprises (MSMEs). Amidst the ever-changing complexity of the business environment, an efficient approach is needed to identify, analyze, and address the risks faced by MSMEs. This research aims to investigate the implementation of web-based Decision Support Systems (DSS) using the Certainty Factor method as a risk management strategy for MSMEs. The risk data obtained will be used to build a knowledge base in the form of a decision support system integrated into a web application. The implementation of web-based DSS provides wide accessibility advantages for MSMEs in managing risks. By utilizing the web application, MSME stakeholders can identify relevant risks in their field of business, analyze the impact and probability of each risk, and receive appropriate action recommendations. The results of this research indicate that the implementation of web-based DSS using the Certainty Factor method is effective in supporting MSMEs in risk management. MSMEs that utilize this application can make more informed and timely risk decisions, reducing potential losses. Therefore, it is hoped that this research can make a significant contribution to enhancing the resilience of MSMEs in facing the complexities of the business environment.

Flooding is a natural event that can have serious impacts on ecosystems, the economy and human life. In efforts to mitigate and control flood risks, early warning plays an important role in providing quick information to the public and the authorities. In this context, the application of the Internet of Things (IoT) provides an innovative solution by utilizing the latest technology to create an efficient and accurate flood early warning system. This research is intended to create a prototype river water level monitoring system using NodeMCU and the Telegram application programming interface as a first step in anticipating flooding. The main objective is to provide assistance to supervisory officers in monitoring river water levels in real time. This research method includes the development and integration of sensors connected to an IoT network to accurately detect changes in water level. The system also implements efficient data analysis algorithms to determine whether conditions require early warning. Telegram was chosen as communication platform to convey warning messages to the public. The IoT device is connected to a buzzer which will provide a sound warning when the water level reaches a threshold. The research results obtained show that water level conditions in the range of 2cm-50cm are categorized as Alert 1 status, so the buzzer (Alarm) is On. In the 51cm-99cm range, the status is Alert 2, and in the 100cm-400cm range the status is Alert 3 with the buzzer Off. Apart from that, via the Telegram bot the status of Alert 3, Alert 2, and Alert 1 will be informed
