Abstract

The development of information technology is growing so fast which has resulted in the emergence of increasingly fierce business competition. The application of information technology in the retail business can certainly help in simplifying and accelerating business processes. Toys Amanah is a family shop located on Jl. Kemandoran Pekayon RT 04/RW 023 Pekayon Jaya Village, South Bekasi District, Bekasi City, West Java Province. This shop sells a variety of toys and office stationery supplies. In its business process, this store still carries out sales transaction activities manually using receipts and notebooks for recording sales data and collecting data on goods. Therefore, in the transaction process, errors often occur in calculating the amount of money that must be paid by customers and it takes a lot of time to record reports and frequent inventory data errors that result in discrepancies between the inventory data and the physical goods. The next problem is that the store wants to give discounts to customers who often come in order to increase customer loyalty, but there is no system that can record loyal customers. In defining requirements and analyzing and designing systems for companies, data collection methods are needed by means of literature study, observation, interviews, design, implementation, and testing. For the analysis method and the concept of this information system, the unified modeling language (UML) model is used. The results of this study will be the construction of a web-based point of sale information system which is expected to be able to deal with the problems that exist in the store. This information system is made using the PHP programming language, MySQL database. With this point of sale information system, it can handle complaints experienced by the store in the process of the system running. Such as an error in the sales transaction process and data collection of goods and the length of time required to process sales reports.

Abstract

Fishing boats are generally made of wood, but over time the availability of wood for shipbuilding began to become difficult to obtain, considering the increasingly expensive price for the type and quality of wood, such as teak. So that other wood alternatives are needed to replace teak, such as laminated white teak. White teak wood can be an option because it grows fast and is widely planted and has a texture that is almost the same as teak. Therefore, it is necessary to conduct research to determine the strength value of white teak laminate through bending testing. The purpose of this study was to determine the value of the bending strength of laminated white teak (Gemelina arborea) and the comparison results with natural teak (Tectona grandis). This study uses five types of variations with the same size 2x2x36cm, namely KJ (Teak Wood), KJP (White Teak Wood), LKJP (White Teak Lamination) two, three, and five layers referring to the Japanese Industrial Standard (JIS Z 2113). , 1963) to determine the value of the bending strength, then an analysis of the average value of the bending test results was carried out and compared with the bending value of teak (Tectona grandis). From the results of the tests carried out, the average value for KJ is 215.53 kg/cm2, KJP 173.35kg/cm2, LKJP 2 layers 176.75 kg/cm2, LKJP 3 180.15 kg/cm2, LKJP 5 149.56 kg/cm2. Based on this average value, Laminate white teak is still lower than the average value of natural teak.

Abstract

Production activities at manufacture companies are often inconvenient. One of them is due to the incompatibility of workers anthropometry with the work facilities used. Disergonomics like this will cause complaints in the skeletal system. Complaints to this damage are termed musculoskeletal disorder (MSDS). The production process of making shoes at UD. Kurnia at the subordinate work station identified that work posture has the potential to cause injury to the arm, back and leg muscles with a percentage of 66.67%, 68.89% and 30%. So it is necessary to improve work posture. In this study, the OWAS method was used to identify and evaluate hazardous work postures. Meanwhile, to improve work posture, work facilities are designed using anthropometric data for subordinate work station workers. Owas identification results show that the work posture is more ergonomic. Then the results of the WinOwas software show that the improvement of work posture with the design of work facilities is included in category 1. Which means that the work posture is not dangerous. So it is directly believed that workers complaints on skeletal muscles or MSDs at subordinate work stations can be minimized.

Abstract

The Multibeam Echosounder is a tool for determining the depth of water by sweeping large areas of the seabed. The operating principle of this tool in general is based on the emission of pulses that are emitted directly towards the seabed and after that acoustic energy is reflected back from the seabed (seabel), several sound beams (beams) are electronically generated using signal processing techniques so that the beam angle is known. . Multibeam echosounder can produce high-resolution bathymetry data. The Multibeam Echosounder is characterized by the following parameters Frequency in the range 12 to 500 kHz. Sweep angle range is between +75 ͦ to 85 ͦ , Accuracy generally decreases as swath width increases. The width of the sweep is 4x to 5x the water depth and the addition of the swath width depends on the depth of the survey. Using Multibeam Echosounder (MBES) acoustic equipment can improve data quality and the survey area coverage is able to obtain data coverage with a wider area, more detailed data as well as time efficiency and cost effectiveness
