The inventory management information system at the Faculty of Science and Technology (Saintek) at Ibrahimy University is designed to facilitate the management of assets, including the recording of incoming goods, outgoing goods, loans, and returns. This study uses a qualitative method with data collection techniques through observation, interviews, and literature review. The result of this study is an information system capable of managing inventory efficiently and effectively, as well as producing accurate and timely reports. The system is designed using Data Flow Diagrams (DFD) and Entity Relationship Diagrams (ERD) to illustrate data flows and relationships between entities. With this system, it is expected to improve inventory management and support the smooth operation of the faculty

Jeru Curah Village Office is a government organization located in Jeru Curah Village, Panji Subdistrict, Situbondo District. Making a certificate is one of the services offered by the Jeru Curah Village Government to its citizens. Previously, certificates were made manually, which required residents to come to the Village Office to fill in the required documents and be verified by the manager. However, this process often experienced problems, such as residents' ignorance of the letter-making process, the need to visit the Village Office frequently due to limited working hours and not meeting certain requirements, thus reducing the effectiveness and efficiency of this service. A web-based certificate service information system should be created to overcome these problems. This research includes interviews, literature observation, and observation as data collection methods. The Waterfall method which has five stages of communication, planning, modeling, building, and implementing is used to design this system. The system was built using PHP programming language and MySQL database.Testing with Google Chrome shows that this approach provides reliable results. A web-based service information system that can facilitate the creation of certificate letters by village office officers, save work time, and facilitate the lives of citizens as a consequence of this research. easily simply input the required information, and is available online through the website.

Traditional doors usually consist of a housing or padlock and a flip key to open it. Usually found on office or mall doors, doors can be made more practical. The door will open automatically if there is physical energy (stimulus) that moves it. For example, when someone wants to enter the room, the door will automatically open. Doors like this are designed using automatic control using embedded system equipment. This automatic door system can be designed using automatic control combined with PIR sensors and servo motors. In terms of input equipment, a PIR (Passive Infrared Receiver) sensor is used which will detect humans approaching the door. This PIR sensor will send a signal to the Arduino process unit which contains a microcontroller chip. This microcontroller will send the processed data to the servo motor, so that it can open or close the door automatically.

Penerapan teknologi Internet of Things (IoT) telah memberikan kontribusi signifikan dalam meningkatkan efisiensi dan kenyamanan dalam berbagai aspek kehidupan, termasuk lingkungan kantor. Penelitian ini bertujuan untuk merancang dan membangun sistem kontrol dan monitoring AC dan lampu berbasis IoT di kantor bagian tata pemerintahan dan kerjasama Kabupaten Bondowoso.
Metode pengembangan sistem yang digunakan adalah metode Prototype, dimulai dari identifikasi masalah, desain cepat, perencanaan, pembangunan prototype, evaluasi pengguna. Komponen utama sistem meliputi sensor DHT11, relay untuk kontrol AC dan lampu, mikrokontroler ESP32, dan platform IoT untuk menghubungkan semua komponen.
Sistem ini memungkinkan pengguna untuk mengontrol dan memonitor kondisi lingkungan kantor secara real-time melalui aplikasi blynk atau web. Dengan adanya sensor suhu, pengguna memonitoring suhu ruangan dan relay untuk menyalakan lampu.
Implementasi sistem ini diharapkan dapat meningkatkan efisiensi energi dengan mengoptimalkan penggunaan AC dan lampu, serta memberikan kenyamanan bagi pengguna kantor. Selain itu, data yang terkumpul dari sistem ini dapat digunakan untuk analisis lebih lanjut dalam upaya meningkatkan efisiensi dan produktivitas kantor.
