Abstract

The making of concrete barrier on the KAPB Toll Road Project Package II Section 1 still uses manual formwork. The use of manual formwork is considered easier to implement, but less efficient because concrete barrier in the form of prototypes should be done practically. Innovation in the field of construction has created Slipform Paver to print concrete barrier. Slipform pavers are believed to be able to produce better productivity than manual formwork. This study analyzed productivity, work duration and costs in the use of molding concrete barrier as an effort to accelerate work. Observations on the making of concrete barrier were carried out in one cycle time from land preparation to finishing the work. Concrete barrier made with manual formwork use readymix concrete FC 20 slump + 10 cm, while slipform pavers use readymix concrete FC 20 slump 4-5 10 cm. The results of the study showed that in making concrete barrier the use of slipform pavers can accelerate the completion of work by up to 46.01% and save costs by 14.3% compared to using manual formwork. In working on all concrete barrier using manual formwork can be done, but requires additional resources so that it can be completed on time.

Abstract

This study aims to determine the technical specifications of a digital QR Code system for the weighing process of practical spice powder recipes using Axiomatic House of Quality to prevent human error. User requirements data were collected from 25 respondents and validated through a Focus Group Discussion (FGD) involving 9 technical experts. The results identified 14 Customer Attributes (CA), which were subsequently translated into 14 Design Parameters (DP). Design matrix analysis indicated that the system is categorized as an uncoupled design, where each Functional Requirement corresponds to a specific DP, thus maintaining the independence of functions and design parameters. The resulting technical specifications are practical and applicable, covering hardware components, user interface, alarms, data storage systems, and material detection mechanisms. Therefore, the designed digital QR Code system can prevent weighing errors caused by human error and enhance product quality from the consumer’s perspective

Abstract

Wonorejo Surabaya Nursery plays an important role in providing plants for green open spaces and urban greening programs. This poses challenges in managing the efficiency of land allocation, plant selection, and seed distribution. This study aims to develop an integrative model using the TOPSIS method to determine the best plant criteria, as well as the Stepping Stone and Simplex methods for optimizing distribution and resource allocation. TOPSIS is used to evaluate plant alternatives based on five main criteria. The results of the study show four priority plants, namely Bromeliad (0.47487), Gandasuli (0.46952), Spiderlili (0.45214), and Adam Hawa (0.59221). The next step is to create a Simplex model with 5 existing constraints, namely land area, water availability, number of workers, personnel working hours, and soil and compost availability. The Z max value is 23.668 with the Adam Hawa decision variable value of 40. For the distribution model, the Northwest Corner method is used and optimized with the Stepping Stone method, resulting in an efficiency of 0.88%. The integration of TOPSIS, Stepping Stone, and Simplex can reduce operational costs and also improve the quality of decision-making to truly support the sustainability of the city's environment.
