UTILIZATION OF DHT11 AND HC-06 SENSORS IN HUMIDITY AND TEMPERATURE CONTROL OF MUSHROOM CAGE

The need for food and healthy food is increasing now with the development of technology about food processing, especially foods with mushroom types. Oyster mushroom is one type of mushroom that is safe for consumption, because oyster mushroom is one kind of complementary food besides rice which has high nutritional value. Due to having a considerable economic value resulting in a lot of oyster mushroom cultivation which is a type of small business that starts from breeding, production, and processing of oyster mushrooms. Oyster mushrooms can grow in the area around the house, oyster mushroom cultivation takes into account several factors including air humidity, air temperature, and lighting regulation, this type of fungus should not be exposed to direct sunlight. In order to maximize yield, we need a kumbung. making the ideal kumbung namely mushroom kumbung which is always awake to the humidity of the air. While the media used is wood powder media mixed with katul with a composition of 15%, 2% lime, and 5% corn powder. Then the mixture is mixed with water with a composition of 60% and stirred, allowed to stand and check the degree of acidity. Then cooled put into polybags plastic and put in a barrel for cooking process (Steam) for 7 hours to sterilize the media. As for the humidity temperature is maintained between 23- 280C. The problems faced by oyster mushroom farmers in Jember City are the regulation of air temperature and humidity that are erratic, when the hot air is very dry humidity, and during the rainy season the humidity is very wet so that it interferes with the mushroom production process. So we need a mechanism that is able to deal with these problems by implementing a mushroom kumbung humidity control system automatically by using a DHT11 sensor connected to Bluetooth HC-06. The function of the DHT11 sensor has been adjusted to the temperature of oyster mushroom humidity. And the second solution is to help control the production and marketing processes by utilizing an integrated management information syste

Pengujian Filter EGR (Exhaust Gas Recirculation) Terhadap Efek Blow By Gas Berbahan Serat Kedelai Edamame Sebagai Upaya Untuk Mengurangi Emisi Gas Buang Mesin Diesel

The growth of diesel-engined vehicles in Indonesia is now increasing as the population grows. Diesel-engine vehicles are in great demand because they have high economic value compared to gasoline-engine vehicles because Diesel-powered vehicles require Solar fuels that cost much less than gasoline-engine vehicles. And also Diesel-engine vehicles have much more power to carry large and large items. However, Diesel-engine vehicles have a negative effect as well as causing large air pollution to the environment. Due to diesel engine exhaust emissions have a high concentration. This high density is caused by the Blow By gas effect of bringing back the remaining oil called soot into the combustion chamber after the combustion process. So in this study the authors modify the Filter EGR (Exhaust Gas Recirculation) from filter made from paper with Filters made from Edamame soybean Fiber Composite. According to Xiaobing Liu Research (2017) that Soybean Fiber can absorb particulate dust with high efficiency level that is between 99.94% and 99.95%. It is expected that this modification may reduce the level of Diesel engine exhaust gas concentration or so-called Opacity Level to the Blow Effect By the gas. From the results of the research, it is found that before the EGR filter (Exhaust Gas recirculation) installed made from Edamame soybean there is an Opacity value of 40% with a value of k-value of 2.58 1 / m. And after EGR filter made from Edamame soybean fiber installed there is a decrease of Opasitas level by 27% with value of K-Value equal to 1,6 1 / m. testing conducted on vehicles at 5000 rpm. Keywords— mesin diesel, tingkat opasitas, serat komposit kedelai, filter EG
