Inventory is one component of company assets which is very important in supporting the continuity of operational activities of trading companies. The process of inventory mutation, makes business owners required to be able to provide accurate and relevant information about inventory. This information can be generated from the use of a merchandise inventory information system which can help business owners to know the processes related to the availability of these merchandises. To monitor the process of oil transfer and oil availability on the CV. Sumber Lumas Semarang, business owners still use manual data input by using Microsoft Excel applications and hand-written stock cards. The manual use of this system causes several obstacles, including: frequent occurrences of oil inventory balances due to human error factors in recording items on stock cards, over-stock/stock out of oil inventory in warehouses and late oil inventory reporting due to data from stock cards moved into the Microsoft Excel format every month that requires precision and a lot of time. This makes the oil inventory report is not up to date. Observed at the problems faced today, CV. Sumber Lumas Semarang needs a system which can overcome the problems of merchandise inventory record and can produce relevant and accurate merchandise inventory information.

In operating a computer, of course, often experience problems with the Windows operating system, such as a slow computer when reading data, missing icons on the desktop, application system crashes or files that can not be run, or error messages appear that are not understood, problems that arise this is not uncommon fatal so that it interferes with the work or activity that is being done. One of the right solutions to the above problem is by applying an object-oriented design that follows the Hierarchy rules (tree rules), which is that each stage will bring up several new stages and Forward Reasoning inference techniques with Dept First Search data search techniques, with the forward reasoning system the system will provide information for the problems encountered. The test results show the solution to the problem of any computer damage problem can help computer users to recognize and deal with computer damage.

Abstract The development of computer and internet science has covered the world community today. including companies and agencies around the world have internet facilities and websites as a form of promotion to the public.

The purpose of this research is to design goods sorting equipment automatically using ultrasonic sensors, load cell sensors. A valid arduino-based servo motor so that the prototype product sorting device automatically uses ultrasonic sensors and arduino-based load cell sensors can be received by PT Wahana Prestasi Logistik Semarang. The method used in this research is the Research and Development (R&D from Borg and Gall) research method. This research discusses about building a sorting device automatically using ultrasonic sensors, load cell sensors, servo motors, conveyors and arduino. The final product results obtained The prototype product is valid, proven from the ultrasonic sensor, the load cell sensor detects the height of the package, and the weight of the package, the tool will sort the items automatically and know the price to pay, then this prototype product has been declared good and accepted by the user (PT Wahana Semarang Logistics Achievement) through user validation,
