Visual monitoring of water clarity in closed laboratory reservoirs poses significant challenges and inefficiencies that may compromise equipment sterilization standards. This study aims to develop an automated water clarity monitoring system at the Research Center for Biotechnology-LIPI utilizing an Arduino Uno microcontroller paired with a BH1750 digital light sensor. The device operates on the principle of light transmission, where suspended particles in turbid water obstruct the light intensity detected by the sensor. Data is processed and transmitted via an Ethernet Shield to a web-based interface for both real-time monitoring and database logging. The research results demonstrate that the device successfully classifies water clarity levels based on light intensity readings, defining clear water as >200 Lux, moderate water as 150-200 Lux, and turbid water as <150 Lux. By providing real-time status updates and automated historical data logs, the system eliminates the need for manual physical inspection. This instrument presents a functional and cost-effective solution to ensure adherence to laboratory water quality standards.

Conventional water monitoring at PDAM Tirta Pakuan Bogor is inefficient and prone to manual errors. This study aims to design a real-time monitoring system to improve operational effectiveness and data validity. Following a four-stage methodology analysis, design, implementation, and testing the device was constructed using an Arduino Uno R3, an Ethernet Shield for stable network connectivity, an ultrasonic sensor, and a 16x2 LCD. The integration of intelligent logic in such systems is crucial for identifying optimal boundary parameters to support decision making. Results demonstrate that the device successfully provides continuous, real-time measurement data via both a web interface and a physical display, aligning with desired specifications. This digital technology support facilitates optimal monitoring through easy access to information. While minor measurement errors occur due to environmental factors, the tool significantly increases the flexibility of information access. In conclusion, the Ethernet Shield and LCD-based system enables reliable monitoring without manual intervention, though it currently requires manual web refreshing to update data.

This research is motivated by the Forestry Museum’s manual reservation process, resulting in irregular schedules and difficulties in managing visitor data. This research aims to build a digital reservation and scheduling platform from scratch using the Prototyping method supported by the Laravel, AJAX, and MySQL frameworks. Functional testing used the Black-Box Testing method, while user experience testing used the System Usability Scale (SUS). The Black Box Testing results showed a 100% success rate. The usability evaluation resulted in an average SUS score of 84.5 placing the system in the Acceptable category. Performance testing resulted in an average visitor form submission time of 0.34 seconds and admin decision execution time of 6.95 seconds, proving the system is capable of processing every data transaction instantly from a technical perspective, thus supporting the smooth flow of overall reservation confirmation. The systems meets the museum’s needs and is easy to use.

This study aims to analyze the internal and external factors influencing the marketing strategy of Tagify, a business engaged in the design of lanyards and ID cards. Using a descriptive qualitative analysis method, the study collects secondary data from literature reviews related to marketing strategies and SWOT analysis. The findings reveal that Tagify's strengths lie in creative design, fast production capability, and flexibility in meeting customer demands. However, the main challenges are limited production capacity and suboptimal use of social media for marketing. Significant opportunities exist in the growing demand for custom products in corporate sectors and large events, while the primary threat comes from intense price competition. The implications of this research show that SWOT analysis is crucial in formulating effective marketing strategies to address challenges, seize available opportunities, and strengthen Tagify's competitive position in the market.

Tactical decision-making in the telecommunications industry requires fast and centralized access to sales performance data. However, performance metrics on the internal corporate website used by PT XYZ are currently distributed across separate modules, leading to repetitive navigation and risks of data inconsistency from manual compilation. This study aims to design and implement a Dashboard Summary feature as a centralized monitoring interface for the Eastern Jabotabek regional division. The system was developed using the Prototyping method, utilizing Laravel as the backend framework and Tailwind CSS for the responsive frontend. The feature integrates three key performance metrics, namely Revenue, Broadband Pack (BBPACK), and Market Share, alongside a Managerial Notes module for the structured documentation of managerial action plans. System validation was carried out through Black Box Testing across 43 test scenarios and direct SQL query comparisons, both of which yielded a 100% success rate. User Acceptance Testing (UAT) involving ten purposively selected respondents produced an overall acceptance score of 95.94%, categorized as Very Feasible. These results indicate that the developed Dashboard Summary feature effectively consolidates fragmented performance data into a single, reliable interface, thereby supporting faster and more consistent operational decision-making.

The Monitoring Onedirection website at PT XYZ does not yet provide a sales data analysis feature based on the 5S components, namely Sales Out (SO), Sales Acquisition (SA), Sales Through (ST), Sales Renewal (SR), and SBP DD Warehouse Stock (SD). As a result, employees still calculate business performance indicators manually using Microsoft Excel, which is prone to errors and inefficient. This study aims to develop a 5S-based Sales Driver feature for the Monitoring Onedirection website at PT XYZ and evaluate its level of user acceptance. The research employs the Rapid Application Development (RAD) method using the Laravel framework. The developed feature consists of six main pages equipped with daily trend charts, four-level hierarchical regional tables, and automatic calculations of Month to Date (MTD), Month over Month (MoM), Year over Year (YoY), and Delta MoM metrics. The Black Box Testing results showed a 100% success rate across 68 test scenarios, while User Acceptance Testing (UAT) involving eight respondents achieved an average score of 92.73%, categorized as Highly Feasible. Therefore, the Sales Driver feature was successfully implemented and proven effective in supporting data-driven monitoring and analysis of sales performance.
