Fish is one of the easiest foods to get, but fish easily spoil. So there are 2 methods to extend the life of fish so that they do not experience a spoilage, namely drying and salting. In the 4.0 era, technology is growing rapidly, one of which is IoT-based technology, in order to help all activities carried out by humans to be more effective and efficient. The purpose of this study is to design an automatic salted fish dryer system using the Internet of Things (IoT) and determine the performance effectiveness of salted fish dryers using the Internet of Things (IoT). The research method of this scientific paper uses an experimental method to test the hypothesis that will be proposed and is useful for predicting an event. Data collection techniques using literature study, data collection, needs analysis, application design and application programming as well as algorithm implementation. Based on the results of the research, the design of an automatic salted fish drying equipment system based on the Internet of Things (IoT) has the ability to monitor the movement of the tool through a smartphone. All components of the appliance can operate automatically just by pressing the start button and setting the duration of the time and the existence of an Internet of Things (IoT)-based salted fish drying device can facilitate and streamline the time when the process of drying fish into salted fish. Initially, small anchovies weighing 100 grams were dried for 3 days, but after using a salted fish dryer, the drying process was reduced to 3 hours (09.00 a.m-13.00 p.m) with a moisture content of 18 grams, while small flying fish weighing 100 grams required a drying process for 5 days (09.00 a.m-13.00 p.m) and would have a moisture content of 30 grams in 3 hours after using a salted fish dryer.

Using smartphones in interpersonal communication among adolescents is now commonplace. Many teenagers who follow the flow of communication media in technology choose smartphones as a more effective interpersonal communication medium. Compared to other forms of communication, interpersonal communication occurs personally, in face-to-face situations, and through media. Interpersonal communication is fundamental since it permits it to require place dialogic communication. Exchange may be a shape of interpersonal communication that appears in the event of interaction. Those included in this communication frame are double-functioning, each being the speaker and the audience, on the other hand. This report analyzes adolescents’ interpersonal communication culture in the smartphone-use era based on this statement. The method used is the phenomenological method. The conclusion of this study indicates that the current adolescent interpersonal communication culture is more influenced by digital technology than direct interaction. Therefore, efforts are needed to foster awareness of the importance of maintaining a healthy quality of interpersonal communication amid technological advances.

This research analyzes the efforts of Akidah Akhlak teachers in reducing smartphone addiction through classical guidance services in Islamic religious education (PAI) learning at MTsN 3 Magetan.

Today is a sophisticated era where everything is digital, be it smartphones, laptops, even safes. So digital password security is essential in protecting personal data. This study analyzes password strength using combinatorics and probability. Calculations are made to determine the number of possible password combinations based on the length and type of characters. In addition, the probability of success of a brute-force attack is calculated based on the number of guesses that can be made by the attacker. The results show that the longer and more complex the password, the less likely it is to be guessed. This study also discusses the concept of information entropy to measure the level of randomness of passwords and its impact on digital security. This study provides insight into the importance of choosing strong passwords.

Oka Jamur Bali is one of the oyster mushroom cultivation farmers. Lack of efficiency in regulating temperature and humidity in mushroom barns is an important factor in the growth of mushroom fruiting bodies. This condition requires an innovative solution to regulate and monitor temperature and humidity in the barn area. This research aims to build a prototype using Arduino UNO, ESP32, DHT11, pump and Internet of Things (IoT) technology.  The monitoring system design uses Arduino UNO, NodeMCU ESP32, DHT11 and DC pump with 12V voltage. Arduino UNO functions as a control system to manage and control the temperature and humidity parameters of the mushroom barn environment with the DHT11 sensor used to accurately measure temperature and humidity. The combination of NodeMCU ESP32 and Arduino UNO aims for monitoring through the ThingSpeak platform which can be accessed with a smartphone connected to the internet network. Based on the results of the prototype of the automatic temperature and humidity control system, the system is able to measure the environmental conditions of the mushroom barn with humidity measurement results in the range of 79% - 82% and the average temperature during the test reached 29.35°C. The application of the system was able to reduce the temperature by 2.28% with an average temperature of 28.19°C and increase the relative humidity by 6.27% with an average humidity of 81.1% in the mushroom barn area. The results of income between the income generated by using the automatic temperature and humidity control system tool and the income of farmers without using the tool increased by Rp. 16,416.
