In line with the recent development of technology, various access to health can be done through smartphones. Many developers are looking for profit by making mHealth applications, especially during the Covid-19 pandemic. However, the display features in these apps have not used ergonomic design principles. Therefore, this study aims to design an ergonomic interface design concept for mHealth apps. The method used refers to the meta-principle for designing digital applications. The initial stage was carried out by distributing online questionnaires to identify user needs. The second stage is benchmarking which is done by evaluating the interfaces of the 4 existing mHealth applications. The next step is to develop the meta-principles needed to design the interface for the mHealth application. The final result of this study is an interface design concept for mHealth apps which is obtained by combining user needs data, benchmarking evaluation and meta-principles. The design concept consists of the top, middle and bottom part of application displays.

Indonesian steel manufacturing sector has proven able to survive and even thrive during the COVID-19 pandemic. Its post-pandemic potential is also very large, considering that Indonesia's steel consumption per capita is the lowest in ASEAN. However, the highly volatile business situation and competition mean that it needs to reduce process costs, reduce processing time, and increase productivity; all of which could potentially be achieved by digital transformation. However, there is very limited research on digital transformation in Indonesian steel manufacturing. This research aims to map the readiness, potential benefit, and barriers to digital transformation in Indonesian steel manufacturing using MICMAC matrix method, with validation and verification carried out directly by experts involved in decision-making process on several steel manufacturing entities in Indonesia. Result of this study shown that to prepare digital transformation readiness, Indonesian steel manufacturing should emphasize its effort on preparing strategy and leadership, investment for industry 4.0, innovation policy, competency development, connectivity, and cyber security. The main benefits that should be pursued first are the capability of monitoring in real time and assisting in communication and data flow; whereas the main barrier that should be taken care of first is preparing its organizational change.

Owing to the rapid development of today's globalized era, studies on service quality improvement has been an increasing concern. The service sector, unlike goods, offers intangible products, and it is often difficult to evaluate. Several fundamental techniques were developed to address the issue such as service quality (SERVQUAL) and multi-criteria decision-making (MCDM). However, due to different system natures, the application is often limited to the specific sector such as education sector. Accordingly, this study aims to develop a decision-making model to determine key criteria and to visualize causal relationships among criteria in the education sector. A case study of student admission service in an Indonesian private university is selected. The service has an important role to attract prospective students choosing the university. The integration of SERVQUAL and fuzzy DEMATEL (decision making trial and evaluation laboratory) was selected since the SERVQUAL method is able to identify relevant service quality criteria, while fuzzy DEMATEL can visualize cause-and-effect relationships among criteria. In this study, nine criteria were identified. Then, the fuzzy DEMATEL method determined two key criteria, namely reliability and communication. Besides, two identity criteria were classified, which were: cause criteria group and effect criteria group. A digraph was developed to model the relationships for both cause and effect criteria group. This study may provide a significant implication for the decision-makers (DMs) in education sector when determining an improvement priority in a service system.
在全球化时代飞速发展的今天，服务质量提升的研究日益受到关注。与商品不同，服务业提供的是无形产品，往往难以评估。为了解决这个问题，开发了一些基本技术，如服务质量(SERVQUAL)和多标准决策(MCDM)。但由于系统性质的不同，其应用往往局限于特定的部门，如教育部门。因此，本研究旨在发展一个决策模型，以确定关键标准，并将教育部门标准之间的因果关系可视化。以印尼某私立大学招生服务为例进行研究。这项服务在吸引未来的学生选择大学方面发挥了重要作用。选择SERVQUAL与模糊DEMATEL (decision making trial and evaluation laboratory)相结合的方法，因为SERVQUAL方法能够识别相关的服务质量准则，而模糊DEMATEL方法能够可视化准则之间的因果关系。在本研究中，确定了9个标准。然后，模糊DEMATEL方法确定了两个关键标准，即可靠性和通信。此外，还划分了两个识别标准:原因标准组和效果标准组。建立了一个有向图来模拟因果标准组的关系。本研究可为教育部门决策者在确定服务系统的改善优先级时提供重要的启示。

Sulfur content in Electric Furnace Matte is one of the key parameters in nickel matte process control at PT Vale Indonesia Tbk. (PTVI), a nickel matte smelter in Indonesia. Currently the compliance to standard specification is relatively low due to process variability and control limitation. The sulfur content in Electric Furnace Matte depend on sulfur addition and other operating conditions. In this research, a machine learning approach is used to predict sulfur content in Electric Furnace Matte based on selected predictors. Linear and support vector regression models were built on the training data and used to predict sulfur content on testing data. The performance of each models were evaluated and compared. The linear model shows a 0.5843 coefficient correlation between test data and prediction, with a mean square error (MSE) 0.4207. The support vector regression (SVR), a non-linear model, is built with the same predictors. SVR model improve the correlation to 0.9408 and reduce the MSE to 0.0762. The research has shown the practicality of applying machine learning in nickel matte processing and open opportunity for further research.
