Restaurant Chain

Using a table-service casual dining restaurant chain, we used direct observations to examine how guests’ use of tabletop technology affected their dining time and front of house labor usage. Results from our study showed that dining time was significantly reduced for guests who used the tabletop devices to either order, or order and pay for their meals by 17% and 31%, respectively. We also found that server contact time and table service time required by the servers to manage their guests’ experiences was significantly decreased for the tables that used the tabletop devices compared with the tables that did not use the devices. Practical and managerial implications are discussed.

Traditionally acid mine water is neutralised with lime (Ca(OH)2). Limestone (CaCO3) is a cheaper alternative for such applications. This paper describes an investigation aimed at demonstrating that underground mine water can be neutralised with limestone in a fluidised-bed. The contact time required between the limestone and the acid water, chemical composition of water before and after treatment, and economic feasibility of the fluidised bed neutralisation process are determined. A pilot plant with a capacity of 10k1/h was operated continuously underground in a gold mine. The underground water could be neutralised effectively using the limestone process. The pH of the water was increased from less than 3 to more than 7, the alkalinity of the treated water was greater than 120 mg/l (as CaCO3) and the contact time required between mine water and limestone was less than 10 min (the exact contact time depends on the limestone surface area). Chemical savings of 56.4% can be achieved compared to neutralisation with lime.

SPBU Sempu Jurong provides 4 service facilities and two of them are service facilities for two-wheeled vehichles which have the most dominant queues compared to the entire queue of the existing system. The queue that occurs is due to the unbalance between the number of service facilities and the number of two-wheeled vehicle customers. This study aims to increase the level of service by knowing the number of service facilities and service time at optimal level at SPBU Sempu Jurong. In this study, the method used is the Multi Channel-Single Phase queuing model. The results of this research indicate that the addition of one facility line causes the service time required for SPBU Sempu Jurong for two-wheeled vehicle refueling services to be faster. Based on calculations using the Multi Channel-Single Phase model, it is obtained that the service time with 2 lines of service facilities is 0.291 minutes, while the optimal service time needed with 3 lines of facilities takes the longest of 0.027 minutes. This shows that it is optimal because the speed of time in service can be improved so that customer satisfaction of two-wheeled vehicles with services at SPBU Sempu Jurong Cikaran Utara can be achieved.

Air sumur bor pada salah satu rumah di Jl. SMK 1 Gambut, Kecamatan Gambut, Kabupaten Banjar mengandung konsentrasi besi (Fe) dan mangan (Mn) yang melebihi standar baku mutu menurut PerMenKes RI No. 32 Tahun 2017 yaitu konsentrasi Fe tidak lebih dari 1 mg/L dan Mn 0,5 mg/L. Salah satu teknologi untuk menyisihkan konsentrasi Fe dan Mn adalah Lahan Basah Buatan Aliran Vertikal Bawah Permukaan (LBB-AVBP). Penelitian ini bertujuan untuk menganalisis efektifitas LBB-AVBP dalam menyisihkan Fe dan Mn pada air sumur bor menggunakan tanaman Typha latifolia dan Cyperus papyrus serta menentukan waktu kontak optimal yang diperlukan sistem pengolahan tersebut. Penelitian ini menggunakan reactor berbahan kayu yang dilapisi plastik dengan dimensi 90 cm x 30 cm x 40 cm serta menggunakan tanaman Typha latifolia dan Cyperus papyrus, dengan media tanam tanah dicampurkan dengan 10% pupuk kandang sapi. Sistem aliran LBB- AVBP secara kontinyu dengan variasi waktu kontak 1, 3, dan 5 hari, debit pengaliran 20 mL/menit, 6 mL/menit, dan 4 mL/menit. Hasil penelitian menunjukkan bahwa LBB-AVBP efektif dalam menyisihkan konsentrasi Fe dan Mn dengan tingkat efisiensi penyisihan Fe sebesar 99,94% dan penyisihan Mn sebesar 88,36%. Waktu kontak optimal menyisihkan Fe dan Mn menggunakan tanaman Typha latifolia adalah pada waktu kontak 1 hari, sedangkan pada tanaman Cyperus papyrus waktu kontak 3 hari. Kata Kunci : air sumur bor, besi, Cyperus papyrus, lahan basah buatan aliran vertikal bawah permukaan, mangan, Typha latifolia. The wellbore water in one of the houses at SMK 1 Gambut’s Street, Gambut’s Sub-district, Banjar’s district contains concentrations of Fe and Mn more than maximum limit allowed by Regulation of the Minister of Health the Republic of Indonesia number 32 of 2017, the concentrations of Fe shouldn’t be more than 1 mg/L and Mn 0,5 mg/L. One of technology could be used to eliminate Fe and Mn is Vertical Subsurface flow constructed wetland. This research aims to analyze the effectiveness of LBB-AVBP to eliminate Fe and Mn in the drilled wells water using Typha latifolia and Cyperus papyrus and the optimal contact time required in the processing system. This research using a reactor made of wood coated with plastic with dimension 90 cm x 30 cm x 40 cm using Typha latifolia and Cyperus papyrus with the soil media mixing 10 % of cow manure. LBB-AVBP system continuously with contact time 1, 3, and 5 days, the debit is 20 ml/minute, 6 ml/minute, and 4 ml/minute. LBB-AVBP effective to eliminate the concentration of Fe and Mn respectively at 99,94% and 88,36%. The optimal contact time to eliminate Fe and Mn using Typha latifolia is 1 days, Cyperus papyrus is 3 days. Keywords: Cyperus papyrus, iron, manganese, Typha latifolia, vertical Subsurface flow constructed wetland, wellbore water.

Social media sites serve as lead generators for achieving marketing communication and raising brand awareness for casual-dining restaurant firms. This study attempts to measure social media engagement across different social networking sites (SNSs) and promotional activities for the casual-dining restaurant industry. This study also explores the influence of the dimensionality of social media engagement on the performance of casual-dining restaurants. The findings show that the metrics of social media engagement are different across channels and promotional activities. The results also reveal that these metrics have significant positive impacts on casual-dining restaurant performance. Pragmatically, the findings provide an assessment that enables casual-dining restaurant marketers to select the most effective SNSs and implement the most appropriate promotional activities, given the limited marketing budget of small and medium-sized casual-dining restaurants.
