Optimizing Service Dominant Logic in Enhancing the Tourist Revisit Intention Maria Francisca Lies Ambarwati, Idris Gautama So, Sri Bramantoro Abdinagoro, Yosef Dedy Pradipto Binus University Abstract The pandemic era has changed the way people live their lives. The influence of digitalization exposure to people^s activities affects their willingness in spending their free time. The desire to travel makes people choose tourist destinations that can meet the service criteria they set. This study aims to take advantage of service dominant logic on the tourist revisit intention because tourist destination providers have focused on drawing strategies to increase the number of tourists so that the company stays afloat or even excel. A quantitative approach is used to answer the problems in this study. The result shows that the current strategies that are used by tourism destination providers might not be effective and relevant anymore as the tourists in industry 4.0 are not affected by digital marketing through websites and social media. Instead, the tourist revisit intention is highly influenced by the service given that are driven by the service quality and servicescape. This study implies that the future marketing strategies should be focused on services delivered at tourist destinations.

The Dimensions of Expatriates Acculturation in China: A Review Fangling Bi, Anees Janee Ali Universiti Sanis Malaysia Abstract Trade globalization pushes multinational corporations (MNCs) to conduct business in many geographic regions. As a result, talent flow has emerged as one of the main avenues for building the competitive advantage of international organizations. Expatriates^ work performance is crucial for MNCs in terms of significant financial losses if expatriates^ failure rate is high. Therefore, it is necessary to pay attention to identifying what causes the failure of the oversea assignment especially in the era of Covid-19. Drawing on Black^s theory of cross-cultural adjustment, this paper reviews empirical studies on the impact of expatriate management practices on work performance with facets of cross-cultural adjustment as a mediating variable. This paper proposes a new dimension that influences the cross-cultural adjustment of expatriates in China, namely Guanxi. Guanxi is introduced into the research framework of factors influencing the cross-cultural adaptation of expatriates in China. Instead of relying solely on either of the literatures, this integration offers a more comprehensive framework. The findings are expected to add to a growing body of literature on cross-cultural adjustment and work performance of expats and to serve as a base for future research.

Experimental study on the performance of centralized air conditioning system due to different outdoor air conditions Kasni Sumeru, Triaji Pangripto, Vickry Muhammad, Mohamad Firdaus bin Sukri Politeknik Negeri Bandung Abstract It is known that outdoor air conditions give significant effect on the performance of air conditioning (A/C) system. Therefore, this experimental study is proposed to investigate the performance of A/C system with different outdoor air conditions. Four parameters were investigated in this study, i.e., cooling capacity, input power, coefficient of performance (COP) and condensate production rate. The study was conducted on a centralized A/C unit using direct expansion (DX) system with a compressor capacity of approximately 15 kW. The investigation was carried out in two outdoor conditions, namely hot and rainy conditions. As compared to hot condition, the result showed that the average cooling capacity of the A/C system during rainy condition increases by 7.2% (increment from 38.5 kW to 41.5 kW). In the other aspect, reduction in the input power from 16.6 kW for hot condition to 15.9 kW for rainy condition was also achieved. As a result of these increase in cooling capacity and the decrease in the input power led to an improvement in the COP of around 8.5%. In addition, rainy condition produced higher rate of condensate (8.45 l/h), as compared to hot condition (5.43 l/h). In conclusion, the A/C system performs better in rainy condition as compared to hot condition, and higher rate of condensate open up a bigger opportunity for condensate utilization in the future.

Gegerkalong Hilir, Bandung 40012, Indonesia. Abstract This study aimed to evaluate cold water produced by chiller that will be distributed to the fan coil unit (FCU). The cold water distribution system from chiller requires good insulation, especially water pipes in and out of FCU to chiller so water temperature remains stable and chiller performance is not too heavy. Increasing temperature of cold water produced by chiller will affect the performance of the air conditioning system (AC) and the use of electrical energy. The object of this study is chiller unit with 18 FCU units located at the Bandung Electronic Center. Detailed measurements have been taken on the AC system . The results of thermodynamic analysis shows that there is a considerable comparison between the ideal heat loss and the actual heat loss, which is 131,972 kW for supply pipelines and 124,498 kW for return pipelines. Heat loss will also result in increased electricity consumption. The measurement and evaluation results showed the insulation of cold water distribution pipe is not effective enough because there are damaged parts of the insulation, the size or thickness of the insulation used does not match the size of the pipe causing unbalanced chilled water flow rate and heat loss.

Edi Sukamto, ST., MT., Triaji Pangripto Pramudantoro, ST., M.Eng., Cindy Gamas, Verino Apriliano Prio Utomo Department of Refrigeration and Air Conditioning Engineering, Politeknik Negeri Bandung Abstract Nowadays nylon tubes was used on liquid and suction lines especially on moveable Standing Floor and Split Unit Air Conditioner and also another Refrigeration Units. But using nylon tube on liquid and suction line will increase the power consumption. Cindy Gamas analysed that the COPactual, COPcarnot and Efficiency were reduced and the power consumption was increased by using nylon tubes beside of copper tubes on liquid and suction line. The chilling time was also the same using those tubes. In this paper, a further experimental study was carried out to know the effect of atmospheric temperature on the performance of Brine Cooling Unit using nylon tubes on liquid and suction lines. As nylon tubes influence the subcool and superheat of the refrigerant and by using indirect cooling secondary refrigerant on Brine Cooling Unit will increase COP and reduce the energy, it was interesting to know the effect of using nylon tubes on liquid and suction lines of the unit.

Air Circulation Types on Albizia Chinensis Refrigerated Drying Petrus Kanisius Purwadi, A Prasetyadi Mechanical Engineering Department, University of Sanata Dharma Abstract Air circulation is important for drying especially in furniture industry. Choice of air circulation type can affect speed of drying, production time, and logistic process. Understanding the effect of air circulation types in refrigerated drying for wooden boards was the aim of this experimental research. Seventy Albizia Chinensis boards of 2 x 0.2 x 0.02 m3 were tested under closed air circulation and opened air circulation. The closed air circulation recorded 34 hours with 30.4% air humidity and [\50^{o}\]C of the inlet air. The RH outlet air was 65%, and its temperature was [\40^{o}\]C. The opened air circulation had inlet air temperature of [\40^{o}\] with 32% RH. The outlet air of the opened air circulation was [\29^{o}\]C and 75% in temperature and RH, respectively. It also needed 39.5 hours for the opened air circulation to provide expected boards dryness. It can be concluded that close air circulation is more suitable for drying the boards with COP of 17 in comparison to open air circulation with COP of 10.7.

Simulation of Heat Spread Welding Process on Friction Drive Wheel in Longitudinal Resistance Seam Welding (RSEW) Machine Using Nastran Inventor Software Andy Kasdianto1,Adri Fato2, Margono Sugeng3, Miftahul Surur4* Universitas Dian Nusantara *Universitas Pancasila Abstract One of the most important steps inside drum manufacturing is Welding. Generally, the welding step used is an airtight connection called Resistance Seam Welding (RSEW). Resistance seam welding (RSEW) is welding with wheel-shaped electrodes rotated by a friction drive wheel to produce a weld along the joints on the workpiece. The type of connection used in the Resistance Seam Welding (RSEW) process is a lap joint. In this Resistance Seam Welding (RSEW) welding process, damage was found to the friction wheel drive which was suspected to be caused by the distribution of heat received from the electrode wheel. In this study, I will simulate the temperature variation received by the Friction Drive wheel with skd61 material to the service life using Nastran Inventor software. From the simulation results, it can be seen that there is a temperature difference in the Friction Drive wheel which is caused by the difference in temperature given. After conducting research, it was proven that temperature does not affect the service life of the Friction Drive Wheel. This research can be continued by making material changes, reducing pressure and variations in the friction surface on the friction wheel drive against the electrodes.
