Abstract

The improvement of the sales system not only focuses on the advantage result of the sales transaction but also can use another parameter to improve it. One of a parameter used is commission. Giving commissions to the salesperson can improve their work performance and have an impact on increasing sales targets. Based on the study literature, the problem faced by the company is the discrepancy of commission. It canbe affected by several factors such as the commission system are not integrated with the main system, improper formula, or there are many systems used in the company so it the staff are difficult to integrate the system. For example, the company using Odoo ERP to support sales transaction and use commission information system separately. The salesperson must integrate sales data into both of the systems. It can affect the time delay of decision commission. Based on the problem above, we propose a prototype commission system that integrates with Odoo12. The salesperson does not need to integrate data manually into the system because it automatically integrates into the system. This study uses a prototyping model as a software development method. The results show that the commission system can implement on the Odoo12 ERP to decide commission to the salesperson. 70% of respondent agree that system has able to use in order to setting up commission module on Odoo

Abstract

The 1.5 inch pipe rolling machine utilizes an electric motor to drive the pipe holder and a 2ton jack as a pipe press. Although the roller machine is widely used in conventional workshops by using human power, it causes the pipe rolling time to be long and the machine user gets tired quickly. This is due to lack of resources to think about developing and improving the performance of these machines. Therefore, the focus of this research is the design of a 1.5 inch pipe rolling machine using an electric motor as a drive and a 2 ton jack as a pipe press. This research aims to produce a design and machine for 1.5 inch pipe rolling and to help accelerate the pipe rolling process and reduce worker fatigue. This pipe rolling machine consists of several components, namely, the engine frame, electric motor, gearbox reducer, chain-sprocket, shaft, pipe drive wheel, hydraulic pump and so on. The working process of this machine begins by preparing a 1.5 inch x 3 meter pipe then the pipe is positioned above the drive wheel, lowers the upper pressure wheel to the desired depth with a 2ton jack power, turn on the electric motor and press the button to roll the pipe back and forth and so on. up to pipe roll size as needed. The stages in making this machine are design, detailed drawing, manufacturing process, quality control, assembly and testing, data retrieval and data analysis. The research resulted in drawings of the design and manufacture of the machine, the calculation of the rotational speed of the machine for optimal rolling obtained 20.46 rpm and an average pipe rolling time of 6.80 minutes for one workpiece. This machine can still be optimized by adding a workpiece movement limiter when rolling.

Abstract

The use of Small Wind Turbine (SWT) technology is currently being developed in residential and urban areas. The application of SWT can be directly integrated into a building called the Building Integrated Wind Turbine and the industrial area is one area that has the potential to develop the SWT concept as a Building Integrated Wind Turbine. Before designing and manufacturing a wind turbine for a Building Integrated Wind Turbine, data on wind density and direction is required. In areas where wind speed and direction have not been recorded, it is necessary to study wind velocity and direction data in real-time and in real conditions for a certain period. This study aims to map wind density and wind direction with real-time properties in the foundry industry area, Ceper District, Klaten Regency, so the potential value and value of wind density energy can be known. This research method includes data retrieval carried out in real time and in real conditions using the Automatic Weather Station instrument which was carried out from August 6 to September 6, 2021. The data obtained were random data and processed using weibull distribution statistics with Microsoft Excel software. The results of this study indicate an average wind speed of 2,038 m/s in stable conditions and sufficient wind gusts with a power density value of 6,994 Watt/m2. The wind direction tends to be south-east after the wind gusts are hampered by the building profil.
