Abstract

This paper aims to investigate the number of research articles authored by Indonesia and Malaysia affiliated researchers about three issues, namely, public policy, technology, and economics. We focus on articles indexed by Scopus in the ten year period 2010-2019. We obtain that Indonesia affiliated researchers are less productive from the beginning of the period. At the end of the period, Indonesia affiliated researchers produce more number of articles published internationally for public policy, technology, and economics issues. Furthermore, in total for any topics at the end of the period, Indonesia affiliated researchers publishes more articles. However, if we observe the number of published research articles with respect to the number of population, Indonesia?s is still left behind Malaysia?s.

Abstract

Going paperless is an ideal form of the information era with the advantages of being time-efficient, environmentally friendly, proper documentation management, and it is an important step to improve the perception of the organization in the environmental field. From the environmental perspective, paperless is a concrete step to reduce the use of trees for paper. The paperless concept has been proposed by the government and has been legally guaranteed, so various sectors have begun to implement the paperless concept such as in the government, education, and industry sectors. However, there has been limited research that studies how many sectors implement paperless applications, the platforms that are used to develop paperless applications, the impacts of using paperless applications and the challenges for Indonesia. Therefore, this study aims to find out more details in the use of paperless applications in terms of sectors, platforms, impacts, and challenges for Indonesia. The data used in this study are articles of journal accredited by Sinta discussing the development of paperless applications in the government, education, and industry sectors from 2010 to 2019. The data are analyzed using the Systematic Literature Review method (SLR). The results of this study indicate that the sector that constantly develops paperless applications is the education sector, while the dominant platform used to develop paperless applications is the website. The impact of using paperless applications has a positive impact both in terms of performance, budget savings, and solving environmental problems generated by paper waste. Paperless applications are the solution in the digital era in supporting environmental preservation. The challenge is how the government makes regulations to support paperless applications in all agencies and provides financial support to sectors in which the use of paper is classified as significant but lacks funds in implementing paperless applications. Paperless applications must also be easy to use, and users must be provided continuous training so that paperless applications can be implemented easier.

Abstract

This article discusses the application of fractional penalty method to solve dynamic optimization problem with state constraints. The main theories supporting the use of the method are described in some theorem and corollary. The theorems give sufficient conditons for the application of the method. Therefore, if all conditions mentioned in the theorems are met then the resulted solution will converge to the analytic solution. In addition, there are some examples to support the theory. The numerical simulation shows that the accuracy of the method is quite good. Hence, this method can play a role as an alternative method for solving dynamic optimization problem with state constrints.

Abstract

The Savings and Loan Cooperative of Simpeunan Pameungkeut Banda is a cooperative that has been established in Tasikmalaya. The system of lending currently used at Simpeunan Pameungkeut Banda Cooperative is still manual, so the management requires quite a long time. Besides that, the cooperative has not had a system that supports in determining the credit worthiness decision. Thus, the credit is not on target, because it does not fit the specified criteria. For this reason, the writers were to make a research on the comparison of weighted product and smart methods in determining credit worthiness in Pameungkeut Banda Cooperative. The purpose of research was to determine who were eligible and who were not eligible to get the credit given the criteria that have been determined using the Weighted Product method and SMART methods. The results of the analysis using the Weighted Product method obtained the highest value of 0.067 and the lowest value of 0.032, while SMART method obtained the highest value of 79.2 and the lowest value of 25. The results show that SMART method is more effective in determining credit worthiness.

Abstract

Stress is generally defined as a state where someone is mentally disturbed as the response to the adversity that he/she experiences. Junior High School students usually are not aware of the stress that they encounter. This research aims to compare two classification methods of KNN and Naïve Bayes to determine stress level. The data of this research were gathered from 254 respondents from Catholic Junior High School of Don Bosco Bitung. The tests of k-cross validation and percentage split from the data showed that Naïve Bayes method excelled KNN method. With k=3, KNN accuracy reached 86.61% at the highest and Naïve Bayes reached 87.40%. Meanwhile, based on percentage split test, the average of Naïve Bayes accuracy was higher than KNN with percentage of 88.31%. Moreover, for the precision and recall, Naïve Bayes was higher than KNN with 88.30% and 87.40% seen from the k-cross validation.

Abstract

Google Scholar is a web-based service for searching a broad academic literature. Various types of references can be accessed such as: peer-reviewed papers, theses, books, abstracts and articles from academic publishers, professional communities, pre-printed data centers, universities and other academic organizations. Google Scholar provides the profile creation feature of every researcher, expert and lecturer. Quantity of publication from an academic institution along with detailed data on the publication of scientific articles can be accessed through Google Scholar. A recap of the publication of scientific articles of each researcher in an institution or organization is needed to determine the research performance collectively. But the problems that occur, the unavailability of recap services for publishing scientific articles for each researcher in an institution or organization. So that the scientific article publication data can be utilized by academic institutions or organizations, this research will take data from Google Scholar to make a recap of scientific article publication data by applying web scraping technology. Implementation of web scraping can help to take the available resources on the web and the results can be utilized by other applications. By doing web scraping on Google Scholar, collective scientific article publication data can be obtained. So that the process of making scientific publications data recap can be done quickly. Experiments in this study have succeeded in taking 236 researchers data from Google Scholar, with 9 attributes, and 2,420 articles.

Abstract

At this time, leadership and social media are two things that cannot be separated. Social media becomes an information technology media for leaders to be able to communicate about their vision and purpose. Therefore, leaders must be able to use social media effectively in order to influence the community with what they think. There are three problems caused by leaders in social media which are classified into three types such as narcissistic, compulsive and paranoid. These three things become big problems in leadership on social media and therefore, we need the formula to solve the problems. The Johari Window method is a method that has four perspectives in developing four leadership classifications such as open leaders, blind leaders, hidden leadership, and unknown leaders. If these three types and four classifications are put together, a framework will be produced called "Leadership Intelligence (CI2) Framework", the next one will produce a formula S = W.L2, where this formula will produce wise leaders on social media. This journal is the development of the journal Developing "Framework Intelligence (CI3)" Inside Social Media Using Johari Window Methods and The Development and Implementation of Wise Netizen (E-Comment) In Indonesia. As a result, this journal will give an answer and solve the problem of an ethical leader on social media and how to decrease a hoax that can affect the leader on social media. This research will continue until it produces a CI1 formula that will combine culture and leadership into a social media formula in generating positive communication, creating a positive culture and making a big impact on society.

Abstract

Instagram merupakan Social Network Service (SNS) yang populer di kalangan pengguna smartphone. Fakta ini didukung oleh hasil survei dalam laporan yang berjudul “Digital In 2018 In Southeast Asia” yang dihimpun oleh We Are Social, perusahaan media asal Inggris yang bekerja sama dengan Hootsuite. Hasil survei tersebut menyebutkan bahwa Instagram menempati peringkat ketiga aplikasi yang paling banyak diunduh pada tahun 2018. Menyoroti respon pengguna smartphone yang begitu besar terhadap Instagram, maka dalam penelitian ini dilakukan eksplorasi faktor penerimaan sikap pengguna terhadap Instagram di Indonesia dengan menggunakan Teori Uses And Gratification (UGT). Pemenuhan penerimaan Instagram dibagi menjadi Cognitive, Hedonic, Integrative, dan Social Integrative. Dalam penelitian ini dikumpulkan tanggapan dari 400 pengguna Instagram di Indonesia. Data yang diperoleh diolah dan dianalisis dengan menggunakan Metode Structural Equation Modelling (SEM) dan perangkat lunak WarpPLS 6.0. Dari penelitian ini diperoleh dua temuan. Pertama, sikap pemuasan pengguna terhadap Instagram dipengaruhi oleh Cognitive, Hedonic, dan Social Interactive. Kedua, Sosial Interactive Gratification merupakan faktor yang dapat meningkatkan Cognitive Gratification, Hedonic Gratification, dan Integrative Gratification.
