The community has widely used the IoT tool because it makes it easy for users in various sectors. The implementation of IoT does not only require connectivity and devices but also requires a server. Servers that are accessed by many devices will have more and more computing processes on the server. The computing process on the server requires a high-performance but small-sized server device that is easy to connect with other devices. Raspberry Pi, known as an IoT server, is a computer with a small size, cheap, and very energy efficient. The parallel machine was built based on Raspberry Pi using parallel computing technology to have high performance. Nowadays, one of the parallel computing tools is Apache Hadoop. This research using clusters method with four pieces of Raspberry Pi with parallel computing technology using Apache Hadoop tools. Testing is done using Siege tools. The number of requests that used to test web server performance in this research was 10, 50, 100, and 150. The most optimal results are on requests by 50 with an increase of about 260% from a single node to cluster in the measurement of transactions, transaction rates, and throughput. Testing with 150 requests can only increase by 50% to 60%.

E-learning is pervasive in higher education, serving as a handy training option in today's hectic culture. Despite being a widespread phenomenon in both study and practice, e-learning is still far from being utilized successfully in any setting. This is due to a lack of study of the learners' point of view as well as insufficient thinking on the ramifications for the teachers. The first part of this research is a survey of university students' opinions and experiences with e-learning. The findings are both unexpected and expected: first, despite seeing e-learning as a promising future trend, students are still unsure of what it means and have only a limited understanding of its capabilities. Second, despite widespread adoption, there is still a sizable minority of students who have never used e-learning and are uninterested in doing so. Third, while e-learning appears to have more benefits than drawbacks, there are still many areas where it may be improved to make it truly effective. We offer some managerial implications for instructors and educational organizations based on these findings.
Tempe gembus is made from tofu dregs which are fermented by tempe mushrooms rhizopus sp. Fermentation process of tempe gembus using conventional method takes 2 days 1 night/about 36-48 hours with temperatures between 25oC-35oC, humidity 60-80%. To maintain temperature and humidity stability by covering the cloth and opening the cloth. This research will discuss how to maintain temperature and humidity automatically using the ESP8266 microcontroller which controls the temperature and humidity sensors using DHT11. When the temperature is below 35 °C the system will perform an automatic action in the form of a light on. When the temperature is above 35 °C, the system will automatically turn on the fan until the temperature returns to normal. The output of this system is displayed on thingspeak and can be seen through thingsview which can be accessed via a smartphone by utilizing the wireless features found on the ESP8266. Tempe gembus fermentation is strongly influenced by the temperature and humidity of the fermentation room. The test results show that using an automatic control system is 16 hours faster than conventional methods.
