Abstract

This research discusses about the comparison of raw material inventory control CV. Dirga Eggtray Pinrang. It starts with forecasting inventory for the next 12 periods using variations of the time series forecasting method, where the linear regression method provides accurate forecasting results with a Mean Absolute Percentage Error (MAPE) value of 1,9371%. The probabilistic models of inventory control used are the simple probabilistic model, Continuous Review System (CRS) model, and Periodic Review System (PRS) model. The CRS model with backorder condition is a model that provides the minimum cost of Rp. 969.273.706,20 per year compared to another probabilistic model with the largest difference of Rp. 1.291.814,95 per year, with the optimum number of order kg, reorder level kg, and safety stock kg.

Abstract

The The use of technology in the mathematics learning process by high school teachers in the city of Parepare is still lacking. Even though there are many learning media that can be utilized. The Geogebra application is a technological medium that has great potential in integrating mathematical concepts visually and interactively. The aim of implementing this PKM is to provide training to mathematics teachers who are members of MGMP Parepare to develop mathematics learning media at the high school level. The training method used is providing training assistance on the Geogebra application which consists of two stages. The preparation stages consist of observing, coordinating with partners, preparing the service implementation team and preparing the service implementation team regarding the training module. The implementation stages consist of giving a pre-test, providing an explanation regarding the Geogebra application, providing simulation assistance in making mathematics learning media using Geogebra, and providing a post-test. The results obtained from the training showed that 18 out of 20 people or around 90% of teachers were able to understand and apply the knowledge gained in training activities through a post-test given at the end of the activity. Thus, the implementation of the Geogebra Application training activities was considered successful because it had achieved the specified targets.

Abstract

In general, security safe box is currently still using key combination that has some drawbacks. One of the weaknesses is the risk of lossing of the keys and forgetting the lock codes that impact at users of not being able to operate the safe box. Therefore, the researcher is designing a tool that is more practical and safe that can replace the key of security safe box. In the research,  the researcher uses the method of fingerprint and a PIN by  designing a circuit input tool using the output fingerprint sensor and keypad. For the series of processor,the researcher applies the Arduino microcontroller Uno R3 while for series output the researcher applies  three output circuit such as LCD, Buzzer, and Selenoids. Security tool safe box can only be operated by entering PIN and fingerprint which have been registered. Hence, the users do not need to save an object to operate the safe box. Based on the results of testing, this tool is able to open the safe box by inputting 5 registered  ID interchangeably as much as 25 times. The Solenoids then are able to operate when they are given voltage > 9, 5V 350 mA to 12V 800 mA.
