Abstract

Salah satu tantangan dalam budi daya tanaman adalah masalah penyiraman tanaman. Sebagian besar proses penyiraman dilakukan secara konvensional. Penelitian ini mengusulkan salah satu pemecahan masalah penyiraman dengan suatu sistem kontrol penyiraman tanaman otomatis menggunakan logika fuzzy. Sistem yang diusulkan dengan menggunakan dua kriteria yaitu kondisi udara (suhu) dan kondisi tanah (kelembaban). Sistem yang dikembangkan menghasilkan keluaran berupa durasi waktu penyiraman dalam empat kriteria yaitu sangat cepat, cepat, sedang dan lama. Hasil pengujian terhadap kondisi suhu menunjukan error rata-rata sebesar 0.41%, sedangkan pengujian kelembaban menunjukan error rata-rata sebesar 2.3%. Rata-rata durasi waktu penyiraman yang dihasilkan oleh sistem adalah 33.1 detik.

Abstract

Era Society 5.0 is the development of technology-based human activities. Rapid technological developments have an impact on human life, one of which can eliminate jobs and can also create new jobs. The Business and Industrial World (DUDI) is one sector that has an impact on technological developments with the hope that the human resources who will work later are superior human resources so that they can innovate well. This study aims to measure the entrepreneurial personality of SMK students using an expert system application. The methodology used in this research is Research and Development (R&D). There are four stages to do: Definition, Design, Development and Dissemination. The instrument used to measure entrepreneurial personality is inventory (non-test) with four indicators of entrepreneurial personality, namely Extroverted, Leader, Moderate Risk Taker, Ambisious, which have undergone a fit test using Confirmatory Factor Analysis. The result of this research is an expert system application that can recommend jobs based on six career-oriented personality types. Based on the results of data analysis, the Entrepreneurship Personality-based career development application was declared valid, practical and effective in measuring the entrepreneurial personality of vocational students in percentage (0.89) and very practical (91.11) and the results of product effectiveness were 82.47 (effective).

Abstract

Organizations today increasingly rely on digital systems to support daily operational activities, including employee attendance management. Attendance systems are essential in human resource management because they are closely related to discipline, performance assessment, and company administration. At PT. Sembilan Cipta Karya, employee attendance is still recorded using fingerprint devices connected locally, so data processing remains offline. This condition causes delays in attendance recapitulation, limits access to information, and makes administrative data management less efficient. A web-based attendance system is therefore expected to record employee attendance in real time, simplify data management, and generate attendance reports more quickly and accurately, enabling the system to improve administrative efficiency and support management in monitoring employee attendance more effectively. This study aims to design and implement a web-based employee attendance system to increase the speed and efficiency of attendance data management. The research method used is Research and Development with a system development approach based on the waterfall model. The waterfall stages include requirements analysis, system design, implementation, testing, and evaluation. This research was conducted at PT. Sembilan Cipta Karya using observation, interviews, and documentation studies as data collection techniques. The results indicate that the web-based attendance system can record employee attendance in real time, simplify data processing, and provide downloadable data in Excel format for recapitulation needs. The system is also able to reduce the time required for recapitulation. Efficiency testing was conducted by comparing the processing time of attendance data between the previous system and the new system. The old system required approximately 60 minutes for daily recapitulation and 120 minutes for monthly reports, while the web-based system required only about 15 minutes for daily recapitulation and 30 minutes for monthly reports. Based on calculations using the efficiency formula, the system can save up to 75% of the time, showing that the developed system is more efficient than the previous one.
