Hamka’s tasauf modern: an outlook on happiness
Introduction
Hamka (1908-1981)’s Tasauf Modern (Modern Sufism) first
published in August 1939 was a compilation of an earlier year and
a half series of articles on ‘happiness’ from the weekly columns of
the magazine Pedoman Masjarakat (Guidance for Society) where
he was its chief-editor. The first article which appeared through
the magazine’s circulation, dated 21st April, 1937, came with the
reminder from the author, that he was writing in response to
the requests of the magazines’ faithful followers, especially the
elderly who had gone through so much of life’s hardships (pahitgetir).
Bibliometric Analysis on Mental Health of University Students
This study aimed to examine the research on mental health among university students through bibliometric analysis. The study was conducted using the Biblioshiny package in R-Studio. The study employs quantitative techniques and conceptual frameworks in knowledge discovery. On September 30, 2024, the screening process identified all references to "Mental Health," "University Students," and "Academic Performance" in the article titles inside the Web of Science (WOS). The analysis included 172 documents authored by 682 scholars in 133 journals published in the WOS database between 1996 and 2024. There were 476 affiliations between the universities or institutes where the authors served. However, more research is necessary to determine the effectiveness of interventions, such as setting-based strategies, and to identify risk factors and predictors of mental health among university students. By reviewing prior research, bibliometric analysis enables the researcher to identify the most significant author or article within their area of interest. It offers a comprehensive overview of the research field for academics and professionals interested in it. This study's cluster of mental health research will assist in directing future research areas through thematic maps, which serve as a tool for visualizing and categorizing research subjects based on trends in the literature. These maps assist researchers in comprehending the structure, evolution, and trends within the discipline by grouping similar topics, emphasizing main themes, and pinpointing emerging areas of interest. This will refine the selection and concentration of new research avenues with greater potential to advance the field of mental health studies considerably

Implementation of Government Regulation Number 23 of 2018 Related to Income Earned by Taxpayers in The Msme Sector
MSMEs have relatively contributed to the pressure during the pandemic now.This study aims to find out how the implementation related to government regulation number 23 of 2018 income earned by the MSME sector taxpayers in the Regency Bantaeng . This type of research used is descriptive method qualitative . This research data is sourced from the results of interviews with MSME tax payers and KPP Pratama employees who were processed . Data collection methods used in this research are observations, interviews, and document studies in which the author in a manner comes to location researchThe results of this study show a deep bottom application related to government regulation number 23 of 2018 income derived by taxpayers from the MSME sector KPP Pratama has tried to maximize the application of the 0.5% final income tax but not yet fully effective by looking at the realization of MSME tax data collection alone.As for who became a limitation in this study is limited to the territory of being the subject of this study, where this study is only for SMEs in the regional districts of Bantaeng just. And the characteristics / advantages of this study lie in the observation period related to the actual latest tax data that is year 202
Ni-rich lithium nickel manganese cobalt oxide cathode materials: A review on the synthesis methods and their electrochemical performances
The demand for lithium-ion batteries (LIBs) has skyrocketed due to the fast-growing global electric vehicle (EV) market. The Ni-rich cathode materials are considered the most relevant next-generation positive-electrode materials for LIBs as they offer low cost and high energy density materials. However, by increasing Ni content in the cathode materials, the materials suffer from poor cycle ability, rate capability and thermal stability. Therefore, this review article focuses on recent advances in the controlled synthesis of lithium nickel manganese cobalt oxide (NMC). This work highlights the advantages and challenges associated with each synthesis method that has been used to produce Ni-rich materials. The crystallography and morphology obtained are discussed, as the performance of LIBs is highly dependent on these properties. To address the drawbacks of Ni-rich cathode materials, certain modifications such as ion doping, and surface coating have been pursued. The correlation between the synthesized and modified NMC materials with their electrochemical performances is summarized. Several gaps, challenges and guidelines are elucidated here in order to provide insights for facilitating research in high-performance cathode for lithium-ion batteries. Factors that govern the formation of nickel-rich layered cathode such as pH, reaction and calcination temperatures have been outlined and discussed
