Abstract

Every plant really needs water to be able to live and as much as possible to be watered on time, because if it is too late, the growth of the plant will be hampered or even unable to develop and die, therefore there are other alternatives for plant lovers in doing plant care and not making it. We are busy in watering plants, namely using plant watering technology using Arduino electronic control, where this tool can distribute water to each plant by detecting water needs in the plant, if the planting medium on the plant is dry, it will turn on the tool and water the plant. The current method of watering plants requires energy and takes time for us to water the plants and we don't even know whether these plants need water because the surface of the soil is dry, so there is still a lot of water available inside, with this controller the water content can be determined, if the water content in the low soil, the tool will automatically turn on and water the plants

Abstract

Currently, the use of computers is very much needed in the process of processing data into information needed by companies. By implementing a computerized system in a company, it is considered to really help the company in making decisions based on the information produced by the system. The Manggis Mandiri Building Shop is a building shop that is currently developing and operates in the sales of building materials, where data processing of goods and receivables is still done manually and all activity reports on the bookkeeping system are still poorly structured. The obstacles that arise are the time problem where calculating receivables or checking goods data takes too long and also the problem of controlling the stock of available goods which is not very well organized. Therefore, the author designed a web-based application using Php Mysql, Xampp and the Laravel Framework. The source of data obtained is through primary data sources and data collection techniques are carried out by means of observation, interviews and documentation. It is hoped that this system can make it easier for Manggis Mandiri stores to run their business and gain profits amidst a lot of competition. As a result of the research, this application has met the system requirements needed such as recording receivables, stock of goods, reporting goods in and goods out.

Abstract

This research is motivated by the problem of inventory management and spare parts procurement at CV. Daya Putra Pratama, which is still done manually using spreadsheets and physical documents. This condition causes stock data discrepancies, delays in the procurement process, difficulties in monitoring procurement status, and limited information on spare parts availability for technicians. The resulting impacts include increased heavy equipment downtime, hampered maintenance activities, and decreased operational efficiency. To address these problems, a website-based Industrial Maintenance System application was developed that integrates stock management, purchase requests, purchase orders, inventory inspections, and supplier payment monitoring in one centralized platform. The Rapid Application Development method was used through the stages of requirements planning, design, and implementation. The development results show that the resulting application is able to improve inventory data accuracy, accelerate the procurement process, increase information transparency, and support more effective decision-making. Thus, the developed application can support increased operational efficiency and integrated inventory management and spare parts procurement.

Abstract

This study discusses the application of K-Means Clustering and Single Linkage algorithms in classifying the quality of Fresh Fruit Bunches (FFB) of oil palm based on four main variables: ripeness level, oil content, bunch weight, and water content. The dataset consists of ten harvest records representing variations in FFB characteristics. The analysis process began with Min–Max normalization, followed by clustering using K-Means (k=3) and Single Linkage (Hierarchical). The results showed that K-Means produced a lower Sum of Squared Error (SSE) (215.32), indicating more compact and homogeneous clusters, while Single Linkage achieved a higher Silhouette Score (0.914) compared to K-Means (0.892), reflecting clearer separation between clusters. This implies that K-Means is more suitable when compactness is prioritized, whereas Single Linkage performs better when the goal is natural separation. The implementation was carried out through a web-based system at PT. Teguh Karsa Wanalestari 2 Pom, Siak Regency, Riau, to address the problem of manual and subjective FFB quality assessment. The system enables real-time data input, automated calculations, evaluation with SSE and Silhouette Score, and presents results in tables, graphs, accuracy reports, and Gmail notifications. With this system, FFB quality can be consistently grouped into three grades (A, B, C), supporting decision-making in harvesting, distribution, and processing more objectively and efficiently to maintain Crude Palm Oil (CPO) quality.

Abstract

This research is motivated by the limitations of the conventional doorbell system that only uses sound indicators without providing visual information and remote notifications. The research aims to design and implement an Internet of Things (IoT)-based smart doorbell system using ESP32-CAM and Telegram and analyze the influence of XCLK frequency optimization on system stability and response. The method used is a prototype through the stages of design, implementation, testing, and evaluation of the system. The system was developed using the ESP32-CAM as the main controller and camera module, push button as a trigger, buzzer as a voice indicator, and Telegram Bot as a medium for sending real-time visual notifications. Tests were conducted on XCLK frequency variations of 1 MHz, 5 MHz, 20 MHz, 50 MHz, and 100 MHz to evaluate system performance. The results showed that the 20 MHz XCLK frequency produced the most optimal performance with stable image capture, faster system response, and consistent notification delivery. Low frequencies cause response delays, while high frequencies trigger instability and system restarts. Thus, XCLK frequency optimization is based on [pay attention again to foreign terms in italics.
