Abstract

This research focuses on the design and control room miniatures to reduce room temperature and increase humidity values in oyster mushroom cultivation. This miniature control room is designed to be able to maintain a temperature of 15-35°C and 50-80% humidity required by oyster mushrooms. In maintaining the temperature and humidity of the cultivation room, a tool is needed in the form of a fog maker and fan as well as a DHT 11 sensor. The DHT 11 sensor detects the temperature and humidity around the room and the cooling fan will be rotated by a DC motor according to the drive signal given by the fuzzy logic controller and the mist maker. functions to produce dew or increase the humidity of the room, the mist maker will be active if the actual value of humidity is below 85%, but if the actual value of humidity is above 85% then the mist maker itself will not be active. In the results of the temperature and humidity experiment for 2 hours, the initial temperature was 29°C and 81% humidity, for the initial temperature set point value was 26°C and 80% humidity.

Abstract

The Research and Community Service Institute (LP2M) of Politeknik Jambi is responsible for managing the research performance of lecturers and students. The manual data management process often leads to delays in report preparation, reduced data accuracy, and difficulties in analysis. This study designs a research performance management system using Excel Macro as a simple and lightweight solution that does not require complex database software. The method consists of requirement analysis, data structure design, development of automated input forms, and macro modules for validation, recapitulation, and report generation. The implementation results show that the system can automatically generate performance reports, accelerate the recapitulation process by up to 60%, and reduce data entry errors. The novelty of this research lies in the use of Excel Macro as an alternative tool for managing research performance in higher education institutions, where such systems are typically built using web-based applications or dedicated database platforms. This system proves to be more efficient and user-friendly, thereby improving the effectiveness of research performance management at LP2M Politeknik Jambi.
