This year, there are 8 teams from the University of Muhammadiyah Malang (UMM) who passed the National Scientific Week event. One of them is the team chaired by Lutfi Aish, a student of the 2017 UMM Informatics Study Program, who became the UMM team that passed the PKM-T (Student Creativity Program - Technology) scheme.
Together with two colleagues from Informatics, M. Fikri Azhar and Amarul Akbar, also collaborated with cross-sector partners. Namely Safira Rikza Charira, Food Technology student class 2018. They provide solutions to problems experienced by oyster mushroom farmers.
Initially, Lutfi heard the problem directly from oyster mushroom farmers in his village, Karangagung, Tuban. Like most coastal areas, Karangagung Village has a relatively high temperature of up to 34 degrees Celsius with a humidity of 50 to 80%. This makes it less possible for the growth of fungi that require air temperatures ranging from 16-24 degrees Celsius with 60-70% humidity.
The unsuitable temperature and humidity causes the mushroom baglog to be damaged a lot. So that it affects the income of farmers. From 1000 baglogs, baglog damage that occurs can reach 200 baglogs every 6 months. This trouble affects the income of mushroom farmers so that they experience losses.

In addition to affecting the partner's income, the condition of the village also causes the temperature and humidity in the partner's mushroom kumbung to be unstable, so the partners have to do manual watering 5-6 times a day which wastes time and energy so that the conditions of the mushroom kumbung remain at optimal temperature and humidity.
After discussing with colleagues and from the guidance of lecturers Nur Hayatin, S.ST, M.Kom, they finally came up with a design for optimizing temperature and humidity to help oyster mushroom farmers. By cooperating with partner Muhammad Anwar, one of the Karangagung village oyster mushroom farmers who has problems.
The design of this tool has passed PKM funding from the Ministry of Education and Culturealso has passed to PIMNAS 33. "This tool can be implemented to help partner problems related to controlling temperature and humidity in mushroom kumbung automatically," explained Amar, tool designer.
The design of the tool uses an Arduino microcontroller using a jumper cable to connect the humidity sensor, relay and DHT temperature sensor which can be integrated on the board. The tool will be placed on the partner kumbung measuring 4x8x3m with a capacity of 1000 baglogs.

This tool will work if the temperature and humidity of the mushroom house are not suitable. The water will be pumped into the water pipe. The sprayer will mist the top and bottom pipes. When the temperature and humidity are optimal, the sprayer will automatically stop and the LCD display will display the optimal temperature and humidity.
Lutfi assured that the design of this tool was in accordance with the conditions of the partners. On the other hand, the application is easy and the durability of the tool is quite long, which is around 2-3 years. In addition, the price is relatively cheap compared to similar tools. From the results of the evaluation, partners gave a positive response to the design of the tool and hoped that the tool could be implemented in the mushroom house.
"The design of this tool has been demonstrated to our partners, and partners have provided positive feedback. After the activity takes place, partners are expected to be able to apply the tools independently and be able to provide insight and information about the tools to other mushroom farmers in the village, "said Lutfi.
