Business processes that are carried out still use manual recording where purchase transactions, inventory recording, and sales records are recorded in the book. Manual recording was deemed less effective and efficient and also resulted in a more complicated inventory reporting process. The purpose of this study is to develop an inventory information system using the Last In First Out (LIFO) method where the unit sold is the last unit entered, making it easier to organize goods, both entering and retrieving goods, and goods will sell quickly because they follow the trend with the latest models that generate more profit. large and this system is also equipped with a minimum stock limit report aimed at knowing the minimum stock limit of goods so that it can provide up to date notifications about out of stock items. By implementing this system, it is hoped that users will find it easier to carry out their business processes.

This study aims to analyze the effect of work discipline on employee performance with the Work Environment as a Moderation Variable. At one of the private universities in Semarang. The sample is all members of the population using a saturated sampling method. The analytical tool used in this research is Moderation Regression Analysis. Hypothesis 1 testing shows that the value of t count = 2.745> t table = 1.645 with a significance number = 0.005 <? = 0.05 (significant). So (H1) which states that work discipline has a positive effect on employee performance is proven. Regression coefficient ?1 = 0.257 (positive sign), this can be interpreted that the higher the work discipline, the higher the employee performance. Hypothesis testing 2. Testing (H2) shows that the t value of the influence of the moderating variable is 2.599> t table = 1.645 with a significance number = 0.016 <? = 0.05 (significant). (H2) which states that the Work Environment positively moderates the effect of Work Discipline on Employee Performance. The interaction test shows ?2 = 0.175 (positive sign), this can be interpreted that a good work environment will strengthen the effect of work discipline on employee work discipline.

Security aspects is needed in various fields of life today. Safety is becoming a concern for everyone. One of the important concerns is the security of the room. The indoor security system uses Raspberry Pi and RFID based Firebase Cloud Messaging and Motion Detection Camera, is a room security system that includes expensive equipment, so this device is designed for protection or robbery and also provides assistance in advance. . The security system in this room consists of several parts, namely Raspberry Pi as a brain system, selenoid door lock as an electric lock on the door, RFID system and CCTV camera as a detector of the amount of human movement, PIR sensor as a detector of human temperature, alarm as an indicator of intruders which transfers rooms, and database applications as user storage databases for security recorders
 

In today's industry competition the use of a technology is very important, including in inventory management. This system is used to enter inventory data into the database so that there are no errors in the report. So that in it often occurs stock report errors in the availability of goods that result in data not being updated, the system that will be created by the author is a system of inventory information that is useful to overcome these problems. This system is also equipped with reports on incoming and outgoing goods data reports, minimum and maximum stock reports, and Web-based stock data reports. With this inventory information system, it is expected to be able to help the existing problems, facilitate data collection, the system built can provide access rights for each user, as well as facilitate the preparation of reports so that the Program is able to handle existing problems.
