Abstract: The impact of Information Systems towards development and sustainability in the world generally cannot be over-emphasized. Various advanced countries in different parts of the world have positively transformed their society with the use of Information Systems enabled with programming computers and related devices in the last few centuries. The net result was g progress to society, increasing the standard of living with benefits related to quality of life through the development of knowledge, products, and services with the ultimate goal of sustainable development. Notable areas and fields of works in which Information Systems development have undoubtedly contributed towards includes organizational payroll systems, e-commerce, online banking, online bookings of different services, communication systems, e-learning and virtual learning systems etc. Most of these systems are developed in advanced countries and developing countries purchase at exorbitant foreign currency-based prices. However, towards sustainability, developing countries have to get to a point where most of the needed systems are developed in-house. That would strive towards how it has now become well known for some countries that have leapfrogged towards development through progress in Information Systems development such that even advanced countries outsource some of their system development works to make use of their massive human talents at lower costs. Without doubt, that would increase employment rate and should serve a goal for many other developing countries that are especially low in financial fundings, plagued with high unemployment but yet buoyant with high human capital. But such laudable goal would involve developing countries seizing such opportunities and rigorously train programmers who will become the developers of the needed Information systems. We believe actions speaks louder than voice and there should thus be concerted efforts in teaching and learning programming to reach the level of bringing development and sustainability. However, learning programming is a complex task and is one of the subjects that students find challenging. This purpose of this paper is to ensure that our students face reduced difficulties in programming. Poorly designed course, students’ weakness in English language, lack of practice and exercises feedback, and lecturers’ insufficient skills in organizing the material and lack of support by the university were seen as possible factors related to the difficulties. Some of the difficulties involve comprehending learning materials in slide presentations from the lecturers, and low involvement in class interactive visualizations. This study emphasized the need, development and usability of interactive video platform method to enhance teaching and learning of programming. This is different from Learning Management Systems (LMS) in that it directly strives to automate the role of the lecturer or at least a summarized textbook in video form. Enhancing online Video is often attractive to capture lecture content and present direct instruction. The advantages of interactive video platform include benefits such as able to provide 24-hour service that can serve different time zones, able to have knowledge in multiple domains, and can be accessed anywhere by student to be able to learn. Video has become an important part of higher education. This study adopts a qualitative research approach using prototyping research and related method such as participatory design and the design science method. This adopt both single double-loop learning that promotes “doing things better” perspective as well as double loop learning that promotes “doing things differently” perspective towards enabling sustainable development in that future Information Systems developers are able learn to do their work effectively in spite of some compromising situations.

Abstract: The purpose of this study is to analyze the effect of macroeconomic variables, the aviation industry environment, airline operating costs, and airport services on the price elasticity of demand (PED) and the implications of PED on airline performance, tourism performance, and airline service rankings. The research approach uses mixed methods. The population calculation is adjusted to the characteristics of each variable in the period year 2013-2019 and the sample, which comes from a diverse population, is calculated with the average value so that the number of samples (n) = 84. The difference in scale in each variable data is converted through the natural logarithm (LN) before the data is processed. Primary data collection techniques are carried out through survey methods and Focus Group Discussion (FGD); while secondary data collection techniques are carried out through library studies, from the Board of Statistics Centre, airlines, and the Directorate General of Civil Aviation of the Ministry of Transportation. The data analysis technique is descriptive statistical analysis and inferential statistical analysis by using Structural Equation Modeling (SEM)-PLS. The qualitative data analysis technique uses analysis based on the results of NVivo data processing. The results concluded that the macro economy had a negative and insignificant effect on PED, however, the aviation industry environment, airline operational costs, and airport services fees have a positive and significant effect on PED. Furthermore, PED has a positive and significant effect on airline performance, a negative and significant effect on tourism performance, and a positive and significant effect on airline service rankings. It is recommended to the government that (i) airfare pricing arrangements are made based on the PED index per route per flight class; (ii) the government tighten supervision of airline unfair business competition (cartel) & airline services; (iii) provide fiscal policy by reducing the cost of avtur VAT; (iv) maintain currency exchange rate stability and revoke the monopoly on aviation fuel supply at Indonesian airports from PT. Pertamina (persero).
