Authors: Primadani Ni Made Lissa , Ariasih Ni Kadek
Published: September 2021

Financial distress is a condition in which a company begins to show signs of bankruptcy due to a decline in the company's financial condition. XYZ Cooperative is a savings and loan cooperative that needs to be aware of experiencing financial distress. What's more, the XYZ cooperative has experienced fluctuating asset conditions, even for profit in a certain month, it has experienced a negative or loss condition. Another problem that occurred is the covid-19 pandemic which made it difficult for people to carry out their obligations such as paying credit. This made the XYZ Cooperative's income experience a drastic decline from the previous year. Meanwhile, currently XYZ Cooperative does not have a prediction system or has never predicted financial distress in its company Based on these problems, an idea emerged to design and build a financial distress prediction system at the XYZ Cooperative using the Modified Altman Z-Score method. This model was chosen because the financial ratios used in prediction calculations are in accordance with the financial ratios of the XYZ Cooperative. The final result of this research is the construction of a prediction system using the Altman Z-Score Modification method on the desktop-based XYZ Cooperative. From the 3 years of financial reports that were tested from 2017 to 2019, the prediction results were at a safe point, namely the Z value above 2.6. The calculation results for 2017 is 8.19, 2018 is 8.11 and 2019 is 7.82. However, the predicted Z value from 2017 to 2019 has decreased, although it is not significant. The accuracy calculation obtained compares the prediction results with the real situation of the cooperative using the average comparison formula and the typer error II formula. Where from the 3 sample data tested, the results of the sample received were 3 with a data error of 0.

Published: September 2021

Temporary Waste Disposal Site (TPSS) is a place to collect waste from various community activities which will later be transported to the final disposal site by garbage trucks. There are many considerations in choosing a TPSS location, so the selection of a TPSS location is very important in supporting the collection of waste that will be transported to final disposal. The Jember Regency Environmental Service is an agency in charge of waste management, including the selection of TPSS locations. Choosing the location of TPSS so far is still manual, where manual selection cannot be separated from human error, so that choosing the location of TPSS is not accurate can cause new problems in the community. In addition, there is no standardized assessment system in the TPSS selection process, so a decision support system is needed that can be used to assist the process of selecting the best TPSS location recommendations. In making this research system, we implemented the hybrid method of AHP and TOPSIS. Where the AHP method is used to determine the weight of the criteria while the TOPSIS method is used for the selection process for TPSS candidates.

Published: September 2021

The world is growing very rapidly concerning technology. In the next-generation Internet, the existing architecture requires to be upgraded from Host-Centric Networking paradigm to Information-centric networking architecture. The unique aspect of information-centric networking is in-network cashing. Due to the system augmentation and In-network cashing technique, this novel system needs extremely high content security to ensure system integrity and maintenance. 5G network may be supported by the Information-Centric Network due to its high data transmission rate. In order to handle the serious security issues such as attack on confidentiality, authentication and integrity of the content, a Digital Signature based Access Control Mechanism in Information-Centric Network (DSAC) scheme is proposed to enhance security of ICN. Briefly, this new scheme uses Digital Signature, hash function, Trusted Third Party (TTP) and Proxy TTP. The client request for content, after receiving a request, the content provider generates and encrypts content with the digital signature and random value ‘k’ hash function and send it to TTP. After the signing process, the TTP sends the encryption hash key to Proxy TTP. In this proposed scheme authentication, confidentiality, the integrity aspects of the content security are improved.
Regenerating Damaged Myocardium: A Review of Stem-Cell Therapies for Heart Failure
Authors: Fan Dihan , Wu Hanrong , Peng Huashan , Pan Kaichao , Wu Rongxue
Published: September 2021

Cardiovascular disease (CVD) is one of the contributing factors to more than one-third of human mortality and the leading cause of death worldwide. Cardiac myocyte death is a fundamental process in cardiac pathologies caused by various heart diseases, including myocardial infarction. Thus, strategies for replacing fibrotic tissue in the infarcted region with functional myocardium have long been a goal of cardiovascular research. This review focuses primarily on induced-pluripotent stem cells (iPSCs), which have emerged as perhaps the most promising source of cardiomyocytes for both therapeutic applications and drug testing. We also briefly summarize other stems- and progenitor-cell populations that have been used for regenerative myocardial therapy and attempt to generate cardiomyocytes directly from cardiac fibroblasts (i.e., transdifferentiation), which, if successful, may enable the pool of endogenous cardiac fibroblasts to be used as an in-situ source of cardiomyocytes for myocardial repair.
