Abstract

Indonesia is an agricultural country where part of the population works in agriculture. Currently, the measurement of the water level of rice fields in Andiang rice fields still uses manual methods by placing restrictions on rice field irrigation then farmers check their condition periodically directly to the field. From this problem, some prototype is needed to do some monitoring from the condition of rice field waters and send notifications to rice field owners. The purpose of this research is to make a prototype that makes it easier for farmers to monitor the condition of rice field waters so that they do not experience overflow or drought. The method used is research and development to improve existing products by testing their effectiveness. This prototype utilizes HC-SR04 (ultrasonic sensor) as a water level reader and SMS Gateway as a platform in sending and receiving SMS (Short Message Service) from mobile phones. The result of this research is that this prototype is able to monitor the water level of rice fields in Andiang Rice Fields.

Abstract

Abstract- Libraries generally provide lockers for users to store their luggage. Lockers in general still use conventional security by using manual locks. Currently, UIN Suska Riau Central Library still uses conventional key security which is considered easy to duplicate, lose, and damage. The purpose of this research is to improve locker security for user convenience and security through a system integrated with RFID, dual camera monitoring, and telegram notification. This tool has a CRUD (Create, Read, Update, Delete) system embedded in the telegram application managed by the admin. Admin can register, delete, and monitor locker user activities. This tool can identify registered and unregistered RFID tags properly. When a registered user accesses the locker, the system will send a picture of the user and a message to the telegram. Meanwhile, when an unregistered user accesses the locker 3 times incorrectly, the device will send the user's picture and message to the telegram and an alarm will sound for 3 seconds as an indication of an attempted locker break-in. The speed of information notification from the Internet of Things system has a delay in sending images with stability in the range of 3 - 4 seconds with relatively strong internet provider speed stability. Keywords— locker security, internet of things, RFID, dual camera monitoring, telegram

Abstract

Abstract—PT PLN Nusantara Power UP Tenayan is a steam power plant (PLTU) with a capacity of 2 x 110 MW which is a buffer for the electricity system in the Central Sumatra section. In the production process of PT PLN Nusantara Power UP Tenayan it does not always go well,. So that it will have an impact on the production stages of the power plant. One of the production machines that often fails and disrupts the production stage is the steam condenser. This research uses the Failure Mode And Effect Analysis Method which aims to identify the type of failure, cause of failure, effect of failure, and determine the RPN value. The research phase begins with data collection from literature studies, interviews, field observations, data analysis, FMEA analysis, results and discussion, conclusions. Based on the results of the RPN calculation, each component of the steam condenser instrumentation does not exceed the RPN standard limit of less than 200, although the temperature indicator has the highest RPN value but is still categorized as reliable and not recommended for immediate maintenance action. The results of identifying the type of failure are that there are inaccurate indications, there are switches with sticky conditions, there are displays that are unclear or blurry, and there is a mismatch between the data displayed in the DCS and the data displayed in the local area. For recommended actions on the steam condenser instrumentation components, among others, carry out more incentive maintenance every 3 months, make improvements to the specifications of the switch according to the amount of pressure to be measured, move the sensor to a safer area and protected from water exposure, carry out a zero calibration process on the steam condenser instrumentation components every six months.

Abstract

PT PLN Nusantara Power UP Tenayan in Pekanbaru operates a power plant that relies on the Circulating Water Pump (CWP) as a vital part of the cooling system. Based on the results of field observations and interviews, failures in the CWP instrumentation system can cause downtime and reduce operating efficiency, but reliability studies are still limited. This study aims to analyze the reliability of the CWP instrumentation system using the Failure Mode and Effect Analysis (FMEA) method. Data were obtained through field observations and technician interviews, then analyzed based on Severity, Occurrence, and Detection parameters. The analysis identified eight main components, with Risk Priority Number (RPN) values all below the 200 threshold. Based on the results of the FMEA calculation, the limit switch component has the highest RPN value of 160 with the potential for downtime reaching 2 to 3 hours per occurrence. The application of FMEA is proven effective to reduce the risk of failure by 25% based on estimated technical evaluation and failure history.
