Abstract

The fermentation process of cocoa beans is a critical stage in chocolate production that affects the final quality of the product. To ensure that fermentation takes place optimally, monitoring parameters such as temperature, humidity, and pH is necessary. This research aims to develop and validate an Internet of Things (IoT)-based data acquisition system that uses ESP32 and MQTT protocols to monitor the fermentation process of cocoa beans. The system consists of an ESP32 module connected to DHT22 sensors to measure temperature and humidity, and a pH meter to measure acidity. The data collected by the sensors is sent in real-time via a wireless connection to an MQTT broker, where it can be monitored continuously. System testing was conducted in a small-scale fermentation environment. Validation results show that the system is capable of providing accurate and consistent data when compared to manual measurements using standardized tools. The difference between the data collected by the system and manual measurements was within acceptable tolerance limits, indicating that the system is reliable enough to be used in small-scale applications. The system also demonstrated fast response to changes in fermentation conditions, and stable data connection with minimal latency via the MQTT protocol. The developed data acquisition system has successfully acquired data and validated it using standard measuring instruments. The average data error for the pH sensor is 2.78%, temperature sensor 1.41%, and humidity sensor 1.94%. These error values indicate that the performance of the sensors used is good.

Abstract

Internal solidarity and a strong sense of belonging are essential for the sustainability of an organization. A solid and cohesive team enables the effective execution of tasks and the achievement of organizational goals. The behavior of love language among leaders and members is expected to foster solidarity and a sense of belonging within the Indonesian National Police (Polri) organization. This research aims to fill the gap in previous studies by investigating the influence of love language on the sense of belonging and solidarity within an organization. The primary objective of this study is to describe the impact of love language demonstrated by leaders at the Surabaya City Police (Polrestabes Surabaya) and the Satpamobvit of Polrestabes Surabaya. This qualitative study employs a descriptive approach, with data collected through observations, interviews, documentation, and literature reviews. Data analysis is based on Gary Chapman's (1992 & 2015) theory of love languages. The findings indicate that the use of love language by the leaders at Polrestabes Surabaya and Satpamobvit Polrestabes Surabaya positively influences the sense of belonging and solidarity among the members of the organization. The leaders’ love language behaviors encompass the five love languages: words of affirmation, giving gifts, quality time, acts of service, and physical touch. These behaviors have been shown to enhance the solidarity and sense of belonging within the organization. This research has the potential to be expanded to a broader scale, such as the East Java Police Region (Polda Jawa Timur).

Abstract

This study aims to determine the effect of Work Motivation, Work Environment, and Work Discipline on Employee Performance. This study uses a quantitative method with questionnaire and interview data collection techniques. The number of samples was drawn using the total sampling technique. Data management uses SPSS Version 25 software. Based on the study, it shows that Work Motivation on Employee Performance is obtained from the t-value -2.668 < t-table 1.684. So Work Motivation partially shows that it does not have a positive and significant effect on Employee Performance. In the Work Environment, the t-value is 5.952> t-table 1.684. So the Work Environment partially has a positive and significant effect on Employee Performance. In Work Discipline, the t-value is 3.688> t-table 1.684. So the basis of the partial test provisions is that Work Discipline has a positive and significant effect on Employee Performance. Based on the F-value = 36.227 while the F-value = at a = 0.05 with n = 43, the F-value is obtained. The results show that F count > F table, i.e., 36,227 > 2.85. Therefore, it can be concluded that work motivation, work environment, and work discipline collectively influence employee performance at PT. Salttek Dumpang Jaya.
