Salt is a very important commodity for human life. In addition to consumption, salt is also needed in several industries, including for the Chlor Alkali Plant (CAP) industries, pharmaceutical, and non-CAP industries such as petroleum, salting, and others. The demand for industrial salt in Indonesia continues to increase every year along with the growth and development of industries in Indonesia. However, the salt produced by Indonesian salt farmers is still low in quality and can only meet the needs of consumption salt because they only contain about 94% to 95% NaCl. Therefore, local salt is difficult to be absorbed by with salt-based products industry because its purity level does not meet the industrial standards. As a result, imports of industrial salt will increase because local salt cannot meet the industry needs. This study aims to build a conceptual model in order to improve the quality of salt in Indonesia in order to produce a good quality salt that meet the industrial salt standards and can be absorbed by the industrial sector in Indonesia with system dynamics approach. The results of this study are conceptual models regarding internal and external factors that influence the improvement of salt quality to meet the needs of industrial salt. The model can be used by the government and related parties in developing strategies and policies related to industrial salt cultivation. Further research can be done by developing several scenarios to predict future salt cultivation systems.

Electronic-based learning media is essential in the industrial revolution 4.0 era for the advancement of education. Electronic learning (E-Learning) like Edmodo has an important role to support the practice of teaching and learning at universities. Edmodo was chosen as the one of the most effective User Generated Content (UGC) to directly represent users between lecturers and students. The ease and benefits of using Edmodo have never been measured at Ciputra University, Indonesia. Edmodo must be analyzed in order to determine the acceptance and benefits perceived by users. Distribution of samples was conducted using an online questionnaire as the data collection method. The data analyzed were obtained from 94 respondents using descriptive statistics and path analysis. Respondent data were processed using the SPSS software. Technology Acceptance Model 2 (TAM 2) is the most suitable method in analyzing the user acceptance adoption based on its constructs. This study used 10 constructs which had been adjusted to answer problems and focus on explanatory research to measure user acceptance with a quantitative approach. The result indicated that the relationship of the highest indicator with a value of 35% is on the Output Quality (X4) which had a significant effect on Perceived Usefulness (Y1); the lowest indicator has a value of 3.1% on the Perceived Ease of Use (Y2) which does not have a significant effect on Perceived Usefulness (Y1). The overall result also showed that Edmodo can be accepted by users as a reference in education, especially at the university level

The biggest carbon emissions in urban areas are generated from the transportation system, including in Surabaya City where the transportation sector contributes 5.48 million tons of carbon emissions per year, or about 96% of the total air emissions there. With the cities rapid development, urban transportation systems need to be managed appropriately to avoid environment damage. The most effective way to reduce carbon emissions from the transportation system is by reducing the number of private vehicles uses. TOD is one of the solutions that can be applied, which is through the integration of mixed land development and the construction of transit mode transportation systems. TOD allows people to carry out various daily activities with close transportation distances, either using transit modes, walking, or cycling. This study aims to show the benefits of applying TOD in reducing carbon emissions from the transportation sector in Surabaya using a system dynamics model. The model produced can be used as a reference or consideration for the government and other related parties in developing strategies and policies related to the implementation of TOD. Future studies can analyze several TOD scenarios that can be carried out to reduce carbon emissions from the transportation sector in Surabaya.

Improving supply chain management is one way to excel in competition. The selection of suppliers is an important part because the lack of proper supplier selection can lead to losses for the company. In its practice, the supplier selection process is more frequently based on a supplier that can provide the lowest price. This happens because the supplier selection process is considered to be at the operational level and not at the strategic level. The number of raw material suppliers on the construction project makes the developers be careful in choosing the material that is according to the developers’ plans. All this time, the selection of suppliers involves many factors, sometimes a supplier has a good performance in terms of the delivery process, yet lacks in terms of quality compared to other suppliers and vice versa. Therefore, research must be done with a method that can take the factors, both the qualitative and quantitative, into consideration. This study is conducted to identify the factors of the selection of construction raw material suppliers and the support of alternative decision support in the selection of construction raw material suppliers. The purpose of this research is to identify the factors of the selection of raw material suppliers and the support of alternative decision in the selection of construction raw material suppliers. This research is expected to help the construction industry, especially in the city of Jember regarding the importance of knowing the factors of the selection of construction raw material suppliers and the decision of the selection of construction raw material suppliers especially if the selection of the construction raw material is in the power of the developer. The method used is the integration of AHP and Vikor using rough number. This research is expected to facilitate the process of selecting raw material suppliers and the selection of its alternatives.The results of this study gain the order of priority of 9 criteria and 23 sub-criteria. The recommended selection of suppliers based on its ranking on the sand suppliers is sand supplier P3, sand supplier P2, and sand supplier P1. Meanwhile, the ranking for the coral suppliers is coral supplier K3, then coral supplier K2, and lastly coral supplier K1

The management system has been one of the essential components of information technology that uses technology to support operations and management. PT XYZ has 11 departments namely Marketing, Purchasing, Human Resource, Finance, General Affair, Engineering, Warehouse, Meat Processing, Bakery, R & D, Quality Control, and Cafe divisions. The number of employees of the entire divisions is approximately ±800 people. Applications has been used in operating the main business activity at PT XYZ on daily basis. However, the applications are still based on each division which will cause the business process to be out of control and the data disintegration in each division. It can be seen as a disadvantage to the product processing as the operation takes longer; hence, it consequently requires higher production costs. Moreover, PT XYZ still uses 3 of the 7 applications that have been developed, while it's also contributed by having limited number of staff who are able to operate desktop or web-based applications. In view of the above, this study aims to develop a suitable information system strategic plan for PT XYZ. The analysis was conducted by using Anita Cassidy's Strategic Planning, wherein the planning starts from upstream to downstream of the company's business process. Anita Casidy's method consist of 4 (four) stages including visioning, analysis, direction, recommendation. The results obtained were IS strategy, IT strategy and IT management. Based on the results, it revealed that, at the visioning stage, PT. XYZ is located in quadrant I, in which quadrant 1 supports aggressive strategies. The strategy that must be determined in this condition is supporting aggressive growth policy. In the analysis, the IS trends used were device mesh, information of everything, advanced machine learning, adaptive security architecture, advanced system architecture, mesh app and service architecture. It was found 25 ITS solutions in the direction stage. For the recommendation stage, there were 4 classifications of costs: resource costs of Rp. 685,286,896, hardware costs projected at Rp. 18,400,000, license fees of Rp. 304,737,080, and miscellaneous fees to be Rp. 192,240,897

Traffic congestion have caused many impacts and losses both in terms of transportation, but also in terms of environmental, economic and social aspects. The increasing number of private vehicles and the decline in public interest in using public transportation is one of the main factors. The decline in public interest in using public transportation is influenced by several reasons, such as ease of access, lack of modes of transportation available, the duration of waiting time, and the duration of travel time. The TOD concept is used because it is a combination of urban planning development and transportation system design, which can help to solve transportation problems especially in urban areas. This study aims to identify and examine how TOD can increase the use of transit modes and transportation efficiency. This study used the System Dynamics model as a means of conceptual modeling (Causal Loop Diagrams) which will describe in detail the factors that will encourage the use of transit modes and improve the efficiency of the transportation system. The results of this study are expected to help provide an overview for policy makers or related parties in determining future directions and strategies related to the existing urban transportation system.
