Abstract

The purpose of mine dewatering system is to control runoff water that enters mine openings so that the mining process is not disturbed. The rainfall discharge (Q) is 0.0951 m³/second and the runoff discharge (Q) is 0.69 m³/second, making the total mining discharge entering the location 0.781 m³/second. The open channel design has dimensions of Channel wall slope (α) = 60°, Water depth (h) = 0.73 m, Channel depth (d) = 0.83 m, Channel base width (B) = 0.73 m, Surface width (b) = 1.57 m, Wet cross-sectional area of channel (A) = 0.92 m², and Channel wall length (a) = 0.97 m. The sedimentation pond has the following dimensions and compartments: Total length (l) = 104 m; width (b) = 8 m; depth (H) = 4 m; partition width = 4 m; partition depth = 4 m; partition length = 7 m. It consists of 3 compartments: conditioning compartment, separation between solids and mine water, and flow with an area of 277 m² per compartment. The sedimentation pond volume is 3094 m³ with a total area of 830 m². The results of the study obtained information that to control runoff water entering mine openings, a pond capacity as a settling site was needed of more than 3094 m³ with a maximum dredging time of settling pond particles that can be done once every 10 months.

Abstract

The culinary industry is dynamic, and the number of culinary business players is growing faster among other business sectors. This study aims to examine the role of knowledge management in supporting competitive advantage in the halal culinary business. The population in this study was halal culinary business players in Yogyakarta. Sampling was carried out using a non-probability sampling method, with sample selection based on a purposive sampling approach, where the sample was selected based on several criteria, such as halal culinary products, form of business ownership, business age, number of employees, and sales turnover. Primary data was obtained through questionnaires, and data analysis was performed with SPSS software version 25. The results of statistical tests showed that all question indicators were valid and reliable, and the determination test indicated that knowledge management contributed 65.7% to the competitive advantage. The results of the regression test showed a positive and significant influence of knowledge management on competitive advantage. This study shows that halal culinary businesses that have effectively implemented knowledge management can gain a competitive advantage. The better knowledge management is implemented, the greater the company's competitive advantage. Keywords: knowledge management, competitive advantage, halal culinary
