Abstract

Kemampuan untuk mengelola informasi tidak hanya penting untuk keberhasilan akademis, tetapi juga penting dalam mempersiapkan mereka untuk terjun di dunia kerja yang semakin bergantung pada teknologi informasi. Meskipun penguasaan teknologi pada siswa-siswa SMA IT Harapan Mulia sudah cukup tinggi, namun nyatanya tantangan seperti kurangnya keterampilan kritis dalam menilai keandalan informasi online, kegagalan dalam mengimplementasikan praktik keamanan informasi dengan baik, terbatasnya eksposur terhadap alat dan teknik manajemen informasi yang canggih di lingkungan pendidikan formal, dan ketergantungan berlebihan pada teknologi digital menjadi kendala dalam memanajemen dan mengelola informasi digital. SMA tersebut belum mempunyai kurikulum yang membahas mengenai pendidikan manajemen teknologi dan informasi, sehingga pembekalan bagi siswa mengenai topik tersebut menjadi hal yang sangat urgen. Untuk itu, tim pengabdian Universitas Sriwijaya melakukan kegiatan untuk meningkatkan pemahaman manajemen dan teknologi informasi bagi generasi Z. Kegiatan berjalan dengan baik. Metode yang dilakukan adalah pemberian materi kepada siswa-siswa dengan ceramah, diskusi partisipatif dan pendampingan oleh ahli. Hasilnya adalah pemahaman dan keterampilan siswa-siwa menjadi meningkat diseluruh aspek dilihat dari pre-test dan post-test yang dibandingkan. Siswa-siswa sangat antusias dan menjadi lebih sadar akan pentingnya manajemen teknologi informasi.

Abstract

This study aims to determine the economic value, which is a direct and indirect benefit (tangible and intangible) of Parak in the research area. This research used a case study method, and the sampling was carried out in a purposive manner consisting of 50 sample farmers. The data used in this study are primary data and secondary data. Preliminary data were obtained by direct interviews with respondents based on the questionnaire provided, while secondary data were taken from agencies related to this research. The processing of data obtained in the field shows that Parak plays an important role in supporting the economy of farmers in Nagari Paninggahan either directly or indirectly. The direct use value obtained from the plant is IDR. 46,753,650 (66,316 per cent), from firewood of IDR. 23,070,000 (32,722 percent) and from livestock IDR. 678,550 (0.963 per cent) so that the total direct use income is IDR. 70,502,200 per year of all commodities cultivated by the sample farmers. Meanwhile, for indirect use, such as household/domestic water use, IDR. 13,312,320/year and agricultural irrigation water IDR. 54,052,111/year. The total indirect usage is IDR. 67,364,431,-. Per year. Agroforestry patterns can cover the soil layer well and have an effective influence on soil erosion control to increase the supply of water in the soil. Respondents have also carried out other conservation activities by constructing bench terraces, terracing systems, and other buildings to suppress sedimentation and erosion.

Abstract

Background: Diabetic foot is a significant complication for Type 2 Diabetes Mellitus’s (T2DM) patients. Previous studies have linked diabetic foot to micronutrients such as ferritin, vitamin D, and calcium, but there have been no follow-up studies in Medan. Objective: This study aimed to analyze the relationship between levels of ferritin, vitamin D, and calcium with the severity of diabetic foot, as measured by the Wagner-Meggit criteria, in T2DM patients at Adam Malik Hospital. Method: A cross-sectional study with 48 T2DM patients at Adam Malik Hospital from December 2022 to December 2023. Micronutrient levels were measured, and the severity of diabetic foot was assessed using the Wagner-Meggitt classification. Result: The majority of participants (64.6%) were female. High ferritin levels were observed in 91.6% of patients, while 93.75% had low levels of calcium and vitamin D. Bivariate analysis revealed no significant correlations between ferritin, corrected calcium, or vitamin D levels and Wagner grades 2-5 (p=0.515, p=0.646, p=0.377, respectively). Non-parametric correlation analysis showed significant relationships between corrected calcium (p=0.022) and vitamin D (p=0.027) with Wagner grades. Discussion: Among the 48 subjects, bivariate testing found that ferritin levels above 150 ng/ml were not linked to diabetic foot severity. Low calcium levels (below 8.5 ng/dl) were significantly associated with increased severity of diabetic foot (p < 0.03). 93.75% of participants had low vitamin D levels, which also correlated significantly with foot severity (p=0.027). Conclusion: The study concluded that calcium and vitamin D levels correlate with the severity of diabetic foot, whereas ferritin levels do not.

Abstract

Purpose – This study investigates the effect of financial distress on corporate fraud by utilizing various financial distress indicators to assess their influence on fraudulent corporate behaviour. Research Method – The study employs panel data regression analysis using data from 210 companies listed on the Indonesia Stock Exchange (IDX) over the 2015–2019 period. Financial distress is measured using three indicators: Z-Score, Zmijewski Score, and Grover Score. Findings – Descriptive statistics show that, on average, companies on the IDX are not generally experiencing financial distress nor engaging in corporate fraud. However, hypothesis testing provides empirical evidence that financial distress significantly affects corporate fraud. Among the indicators, the Grover Score exhibits the strongest influence on the likelihood of fraud occurrence. Implication – The findings offer theoretical insights for academics and practical implications for regulators and corporate governance professionals. The study suggests that revisiting the conceptual framework and re-grouping indicators in measuring financial distress can contribute to the development of future theories and preventive measures related to corporate fraud.

Abstract

This research aims to develop a differentiated learning strategy that incorporates an inclusive approach in Islamic jurisprudence to enhance student learning outcomes at Madrasah Aliyah Negeri 1 Deli Serdang. This research employed the ADDIE (Analyze, Design, Develop, Implement, and Evaluate) model, developed by Robert M. Branch. The research findings of this study demonstrate the effectiveness and practicality of implementing a differentiated learning strategy with an inclusive approach in Islamic jurisprudence (Fiqh). Learning activity increased across trials, with a score of 2.67 in the first trial (practical with minor revisions) and rising to 3.67 in the second trial (very practical). Most notably, the strategy was found to be effective in enhancing student learning outcomes, as indicated by the results of a statistical paired t-test, where the calculated t-value (17.86) exceeded the critical t-value (2.045). Furthermore, the normalized gain (N-Gain) score reached 0.587, reflecting a moderate level of improvement. Keywords: learning strategy, differentiated learning, inclusive approach
