Abstract

The development of Waste Processing Facilities based on the 3R principles (TPS 3R) with small-scale Refuse Derived Fuel (RDF) technology in Jakarta aims to support waste sorting, composting, reuse, and recycling activities, with locations strategically placed as close as possible to service areas. However, its implementation faces significant challenges, particularly due to high initial investment and operational costs. This study evaluates the feasibility of four TPS 3R facilities using a Cost-Benefit Analysis approach, considering economic, environmental, and social dimensions. The results indicate that all units are economically viable, with TPS 3R Joe demonstrating the highest economic feasibility, marked by a BCR of 1.870, an NPV of IDR 25.81 billion (USD 1.60 million), and an IRR of 15.76%. The study concludes that the successful implementation of small-scale RDF technology is highly influenced by technical efficiency, institutional support, community participation, and policies that are adaptive to local characteristics.

Abstract

Student achievement is a barometer of success in teaching and learning activities. One way that can be done to motivate students to improve learning achievement is to provide scholarships as a form of appreciation from the institution or educational institution where they study. Through the Decision Support System (SPK) can assist leaders in making the right decisions for the selection and awarding of scholarships based on predetermined criteria. The purpose of this research provides more important criteria for determining selection alternatives for prospective beasiswa recipients. This research uses the Analytical Hierarchy Process (AHP) Method. Pairwise comparisons are given to derive the importance of the criteria. Cumulative Achievement Index (GPA), Economic Situation and Non-Academic Achievement. The criteria for economic conditions have sub-criteria for pairwise comparison in the form of parental income and number of siblings, while achievements have sub-criteria whether they have achievements both locally, nationally and internationally or not have achievements. Comparison of paired criteria where GPA has the largest value of 0.63 followed by achievement with a value of 0.26 and economic conditions with a value of 0.11., so that from the calculation results of three alternatives obtained the top rank with a value of 0.531337

Abstract

Background: Cancer is a chronic disease that can cause various complications, decrease the immune system, reduce quality of life, and even lead to death. In addition, the COVID-19 pandemic in various countries has had a significant adverse impact on patients. This study analyzed the impact of various antitumor treatments on cancer patients with COVID-19. Methods: This meta-analysis was conducted according to the PRISMA – P pathway. Source searches were conducted in PubMed, Cochrane Library, Research Gate, and Science Direct in cancer patients with COVID-19 receiving various types of antitumor treatment. Analysis was performed using RevMan V.5.3 software with the outcome of mortality rate and severe COVID-19. Results: Twenty-five observational studies met the inclusion criteria with a total of 21,940 patients. There was no significant difference in mortality rate (OR 1.08, 95% CI 0.99 – 1.18, p = 0.09), but there was a significant difference in severe COVID-19 (OR 1.19, 95% CI 1.02 – 1.39, p = 0.02). Immunotherapy provided the most significant worsening of both mortality rate (OR 1.39, 95% CI 1.17 – 1.64, p = 0.0001) and severe COVID-19 (OR 1.82, 95% CI 1.23 – 2.71, p = 0.003). There were no significant differences in other antitumor treatments. Conclusions: Antitumor treatment does not have a significant impact on mortality rate, but has a significant impact on worsening the degree of COVID-19. Among all the antitumor therapies that provide the highest potential for worsening is immunotherapy.

Abstract

The internet has become an integral part of people's lives, with 5.44 billion users worldwide and 185 million users in Indonesia. Internet use covers a wide range of areas, including entertainment such as video games, which had an estimated 3.38 billion global users in 2023 and continues to grow. The video game industry shows huge market potential, with significant revenues. To exploit this potential, game developers must maintain player loyalty. Player retention, i.e. a game's ability to retain players over a long period of time, is critical in increasing a game's revenue and popularity. Knowing player retention rates is a key strategy in marketing, as high retention is associated with higher loyalty. Previous research has examined player behavior and retention in the context of games, but there is no comprehensive model for various types of games. This research aims to develop a classification model that can identify the characteristics of players with high or low retention rates. This model is expected to help game developers design more effective retention strategies. The findings of this research will provide in-depth insight into the factors that influence player retention and offer guidance for game developers in developing better features and strategies to retain players.
