Abstract

Temperature and humidity in the barn greatly affect the growth of oyster mushrooms. Therefore, it is necessary to keep air circulation inside the barn optimised. Betuah mushroom SMEs faces the difficulties in controlling both optimum temperature and humidity for oyster mushroom growth. Therefore, this serviceaims to utilise Internet of Thing (IoT) technology to regulate temperature and humidity for oyster mushroom cultivation using DHT22 sensors in Betuah mushroom MSMEs located in Tuah Madani District, Pekanbaru City. The stages of the method used include socialisation, training, technology application, mentoring and evaluation and program sustainability. From the service carried out, microcontroller-based automatic temperature and humidity control technology with an IoT system was successfully applied. The resulting tool can control the temperature and humidity in the barn according to the set limits. The produced products improved in terms of quality, which the oyster mushroom's both flesh and color is respectively not hard nor yellow. The quantity of fresh mushrooms produced is stable and increasing per day, ranging from 15-20 kg/day to 20-30 kg/day production

Abstract

Nitrocellulose is an important compound in the chemical industry, which has various crucial applications, such as the main ingredient for making quality paint, ink, and coating formulations in the printing process, as well as a propellant (explosive). Nitrocellulose as a raw propellant material is currently very popular. In this research, pineapple leaf waste has been processed as a raw material for making nitrocellulose through a nitration process. The research aims to determine the effect of the nitration process's length and the nitrating acid's composition on nitrocellulose's nitrogen content. Before the nitration process, an initial process is carried out, namely pre-treatment of pineapple fiber to obtain fiber with a cellulose purity of >92%. In the nitration process, the ratio of titrating acid (H₂SO₄:HNO₃) used is 1:3, 1:2, 2:1, 7:3, and 3:1 with a nitration time of 30, 60, 90, and 120 minutes. The results obtained in this research were that the pre-treatment process was able to increase the purity of cellulose in pineapple fiber by up to 93%. Then the 2:1 titrating acid formulation (H₂SO₄:HNO₃) is the best acid ratio formulation. Meanwhile, the optimum time for nitration is 60 minutes, with a nitrogen content in nitrocellulose of 12.73%. Fourier Transform Infrared (FTIR) analysis shows that there has been an exchange of hydroxyl groups in nitrocellulose with nitro groups, which is indicated by the presence of a peak indicating the nitro group. Apart from that, the burning test also showed that nitrocellulose can be burned faster than cellulose
