Abstract

Milkfish farming in coastal ponds of Ujung Watu Village, Jepara, is highly influenced by the stability of water salinity levels. Significant fluctuations in salinity can interfere with the growth and health of fish, so an adaptive control system is needed. Research methods include field data collection, hardware and software design, and system testing in an active pond for 14 days (23-hour sampling), where data is extracted for 23 hours. The system uses a salinity sensor to detect water conditions, PLC to automatically control the brackish water pump, while wireless remote control uses IoT, in addition to controliing, IoT to send data to the Android-based monitoring platform. The test results show that this machine is able to maintain salinity levels within the optimal range of 10000-30000 ppm, and provide remote monitoring convenience to pond farmers. The monitoring system serves as a predictive for manual wireless control of electric pumps (IoT), while automatic control is controlled by PLC.

Abstract

The presence of modern stores has led to the climate of unfair competition harmful traditional stores. The existence of a minimarket can turn off 20-50 small grocery stores, while a supermarket can be lethal up to 200 grocery stores, while hypermarkets and 500 grocery stores. minimarket establishment, in a radius of 500 meters will result in a decline in income of up to 57.92 percent. At a radius of 1 km to 30 percent. Defeat competing with traditional stores because of low competitiveness. This situation experienced by both partners, traditional shop "Darul Ulum" and Toko Abdul Khamid.These service activities seek to address the problem of lack of competitiveness in the form of partners, and exacerbated by the low-performance service standards for record-keeping and accounting system is still manual. Therefore, the outcome of devotion is a solution to the problem. Such as 1) program to improve competitiveness, 2) development of accounting information systems. The approach used is a method of interactive participation, in which both partners will play a role in the analysis process for planning activities and the strengthening of internal organization.The method of implementation program to improve competitiveness, carried out in phases: 1) a SWOT Analysis, 2) Guarantee of perception and deal program, 3) Modernization store, 4) Training service standards, 5) Training governance and SOP, 6) creation of SOP shops, 7 ) Implementation and mentoring. Program information systems development shops, stages: 1) analysis of requirements and design of information systems, 2) identification and preparation of database product items and members or prospective members, 3) Making accounting software, 4) Application of accounting information systems, 5) training information system accounting, 6) special units of cooperative stores, to disseminate the members, administrators and managers of cooperatives, 7) Implementation and facilitation of the use of the system. As quality assurance efforts in the implementation of each of the partners will be accompanied by two students.

Abstract

This study aims to analyze the factors that trigger employee interest in whistleblowing. The population in this study were employees who worked in the OPD as a financial sub division and one financial staff member from all Regional Apparatus Organizations (OPD) in Jepara Regency using simple random sampling. The results showed that the factors that triggered employee interest in whistleblowing were employee attitudes, organizational commitment, personal costs and the seriousness level of employee fraud. The better the employee's attitude which is shown by agreeing to disclose the fraud, the greater the person's interest in taking whistleblowing. The greater the employee's commitment to an organization, the greater the employee's interest in uncovering the fraud or in whistleblowing. The higher the risk faced by employees as indicated by the high personal cost to reveal the occurrence of fraud, the lower the employee's interest in reporting fraud or the lower the interest in whistleblowing. In addition, the higher the seriousness level in eradicating fraud, the higher the employee's interest in exposing the fraud to the authorities by becoming a whistle-blower, which also means that employees' interest in taking whistleblowing action will be higher.
