umentation and interviews. The input variables used consist of the Age of the Perpetrator, Environment, Socializing, Gender, and Family, while the output variable is the Level of Drug Abuse with Low and High categories. The research stages include data collection, determining variables and fuzzy sets, fuzzification, forming if-then rules, inference using the minimum operator, composition using the maximum operator, and defuzzification using the centroid method. A total of 64 fuzzy rules are used to connect the combination of input variables with the output. Testing is done through manual calculations and implementation using MATLAB. The test results show that the output categories from manual calculations and MATLAB are the same in three test data, namely High, High, and Low. These results indicate that the Mamdani Fuzzy method can be used in modeling the level of drug abuse based on the variables used.

not been optimally implemented. This study implements the 128-bit Advanced Encryption Standard (AES) algorithm combined with Huffman compression to protect the confidentiality and integrity of student grade files in Excel (.xlsx) format, and evaluates its effectiveness through functional, performance, and security testing. The system was developed as a Python desktop application with a CustomTkinter interface, in which the encryption process runs Huffman compression before AES-128, while integrity verification uses SHA-256 hashing. Testing was conducted on seven student grade files from MA Ma'ahid Kudus. The results show that all files were successfully encrypted and decrypted without failure or data alteration, with encryption times of 0.0142-0.0828 seconds and decryption times of 0.0046-0.1417 seconds. The SHA-256 hash values of the original and decrypted files were identical for all samples, yielding 100% recovery accuracy, while the file size increase from padding and header insertion ranged only from 1,092 to 1,101 bytes. The study concludes that the combination of AES-128 and Huffman compression is an effective and efficient solution for protecting student grade data in educational institutions.

Abstract:This study examines how leadership and work-life balance influence employee performance directly and indirectly through employee engagement at the Fisheries Service of Central Maluku Regency. A descriptive quantitative,…
causal-correlational design was applied to the entire population of 49 employees using total sampling. Data were analyzed through descriptive statistics, path analysis, and Sobel tests to estimate direct, indirect, and mediating effects. The findings show that leadership significantly affects employee engagement (beta = 0.582; p < 0.001), while work-life balance also has a significant, although smaller, effect on engagement (beta = 0.129; p = 0.005). Employee engagement strongly affects performance (beta = 0.942; p < 0.001). In contrast, the direct effects of leadership (beta = 0.034; p = 0.613) and work-life balance (beta = -0.008; p = 0.756) on performance are not significant. Sobel testing confirms that employee engagement mediates the effect of leadership on performance (p = 0.00015) and the effect of work-life balance on performance (p = 0.03). The model explains 92.4% of the variance in performance. The study's novelty lies in demonstrating, within a local public-sector context, that leadership and work-life balance improve performance primarily by strengthening employee engagement rather than through direct effects. These findings imply that public organizations should prioritize engagement-oriented leadership and work-life policies to achieve sustainable employee performance.

Abstract:This study aims to examine the influence of deferred tax and tax planning on earnings management in primary consumer goods sub-sector companies listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. The…
The variables employed in this study are deferred tax and tax planning as independent variables, and earnings management as the dependent variable. Panel data regression analysis was utilized to assess the influence of the independent variables on the dependent variable, both simultaneously and individually. The study population consisted of 83 companies, with a sample of 32 companies selected via purposive sampling, resulting in 160 observations. Data processing was conducted using EViews version 12 software, and the Common Effect Model (CEM) was selected as the model. Hypothesis testing using the model feasibility test (F-test) indicated that the model is suitable for measuring the influence of the independent variables on the dependent variable. The research results show that: (1) deferred tax and tax planning simultaneously have a significant effect on earnings management; (2) deferred tax does not have a significant partial effect on earnings management, indicating that deferred tax does not directly drive earnings management; and (3) tax planning has a positive and significant partial effect on earnings management.
Abstract:This study examines the effect of Environmental, Social, and Governance (ESG) disclosure, green investment, and sustainability reporting quality on firm value, with firm size as a moderating variable in energy sector companies…
panies listed on the Indonesia Stock Exchange in 2024. The study employed a quantitative associative approach using secondary data obtained from annual reports, sustainability reports, and financial statements. Purposive sampling produced 65 observations that met the research criteria. Data were analyzed using Moderated Regression Analysis (MRA), supported by classical assumption tests and hypothesis testing. The findings indicate that ESG disclosure does not significantly affect firm value. In contrast, green investment and sustainability reporting quality have positive and significant effects on firm value. Firm size also has a positive and significant direct effect on firm value. However, firm size does not moderate the relationship between ESG disclosure, green investment, or sustainability reporting quality and firm value. Simultaneously, ESG disclosure, green investment, and sustainability reporting quality significantly affect firm value. The first regression model explains 36.0% of the variation in firm value, while the moderation model explains 74.4%. These findings imply that energy sector companies should prioritize concrete green investment initiatives and improve the quality, completeness, and credibility of sustainability reporting to strengthen market value and stakeholder confidence.
Abstract:This study aims to examine the influence of discount framing, brand reputation, e-satisfaction, and e-loyalty on the use of online food delivery applications. The study employs a quantitative approach using survey methods…
s and hypothesis testing with SEM-AMOS version 23. The population of this study consists of users of online food delivery applications across Indonesia, with the unit of analysis being individuals. Data for this study were obtained from 135 respondents who filled out an online questionnaire based on a purposive sampling method. The results of the study indicate that discount framing has a positive effect on brand reputation and e-satisfaction. Brand reputation positively affects e-satisfaction. E-satisfaction positively impacts e-loyalty. This indicates that the higher the discount framing, the better the brand reputation and e-satisfaction for ordering food. Furthermore, the better the brand reputation, the higher the e-satisfaction, and the higher the e-satisfaction, the better the e-loyalty in ordering food through online food delivery applications. The implications of these results for application owners are to understand the influence of discount framing, brand reputation, e-satisfaction, and e-loyalty, so they can formulate strategies and policies related to these factors. Meanwhile, the implication for application users is that they can use applications that offer discount framing that suits their needs.

dengan kematangan karier adalah keikutsertaan siswa dalam kegiatan ekstrakurikuler. Penelitian ini bertujuan untuk mengetahui perbedaan kematangan karier antara siswa yang mengikuti kegiatan ekstrakurikuler dengan siswa yang tidak mengikuti kegiatan ekstrakurikuler di Madrasah Aliyah Negeri Kota Serang. Penelitian menggunakan pendekatan kuantitatif dengan metode komparatif. Sampel penelitian berjumlah 404 siswa yang berasal dari MAN 1 Kota Serang dan MAN 2 Kota Serang, yang dipilih menggunakan teknik stratified random sampling. Pengumpulan data dilakukan menggunakan angket kematangan karier yang disusun berdasarkan enam aspek kematangan karier yaitu orientasi karier, informasi dan perencanaan karier, konsistensi pilihan karier, pemantapan karakteristik diri, kemandirian dalam memilih karier, serta kebijaksanaan dalam memilih karier. Data dianalisis melalui uji normalitas, uji homogenitas, dan uji komparatif. Hasil penelitian menunjukkan bahwa tingkat kematangan karier siswa secara umum berada pada kategori baik dengan nilai rata-rata sebesar 194,16. Namun demikian, hasil pengujian hipotesis menunjukkan tidak terdapat perbedaan yang signifikan antara siswa yang mengikuti kegiatan ekstrakurikuler dan siswa yang tidak mengikuti kegiatan ekstrakurikuler (Sig. = 0,347 > 0,05). Temuan ini menunjukkan bahwa keikutsertaan dalam kegiatan ekstrakurikuler bukan merupakan faktor yang membedakan tingkat kematangan karier siswa. Kematangan karier diduga lebih dipengaruhi oleh berbagai faktor lain, seperti pemahaman diri, dukungan keluarga, pengalaman belajar, layanan bimbingan karier, dan akses terhadap informasi karier.
Career maturity is an important aspect that students need to develop in preparing for future educational and occupational choices. One factor that is assumed to be related to career maturity is participation in extracurricular activities. This study aimed to examine the differences in career maturity between students who participated in extracurricular activities and those who did not in State Islamic Senior High Schools (Madrasah Aliyah Negeri) in Serang City. This study employed a quantitative approach using a comparative research design. The sample consisted of 404 students from MAN 1 Serang City and MAN 2 Serang City selected through stratified random sampling. Data were collected using a career maturity questionnaire six dimensions of career maturity: career orientation, career information and planning, consistency of career preferences, crystallization of self-characteristics, career independence, and wisdom in career choice. Data were analyzed using normality testing, homogeneity testing, and comparative analysis. The results indicated that students' career maturity was generally at a good level, with a mean score of 194.16. However, the hypothesis testing revealed no significant difference in career maturity between students who participated in extracurricular activities and those who did not (Sig. = 0.347 > 0.05). These findings suggest that participation in extracurricular activities is not a distinguishing factor in students' career maturity. Career maturity is likely influenced by other factors, including self-understanding, family support, learning experiences, career guidance services, and access to career information.
