Abstract

Law No. 22 of 1999 regarding regional autonomy has had a significant impact on education management in Indonesia. Autonomy opens opportunities for educational units to manage schools independently, especially in curriculum development and funding. However, on the other hand, autonomy also poses a threat if schools are not prepared, both in terms of human resources (HR) and finance. Therefore, the success of school financial management depends heavily on the competence of the school principals. Competent school principals in school financial management are the key to ensuring that teachers and staff can deliver education with optimal quality.

Abstract

Employee loyalty is essential for organizational survival, and career development is recognized as a significant contributor to enhanced loyalty. This study seeks to examine the current literature about the correlation between career development and employee loyalty and to propose measures that organisations might adopt to bolster loyalty via career development. Analysis of multiple studies revealed that effective career development programs enhance job satisfaction, motivation, and employee engagement, thereby fostering organizational loyalty. Moreover, supervisory support, a conducive working environment, and work-life balance significantly contribute to cultivating robust connections between employees and the organization. Despite several studies indicating a favorable correlation between professional development and loyalty, a gap persists in the literature, particularly in the examination of the specific effects of different types of career development programs. This study advocates for organizations to establish structured career development programs, define clear career trajectories, and foster a supportive working environment. Future studies should investigate additional elements affecting this association and provide fresh insights into human resource management. This study significantly contributes to our understanding of how career development might bolster employee loyalty and facilitate organizational sustainability.

Abstract

Keterlambatan pengiriman memengaruhi keandalan layanan dan membutuhkan model risiko yang dapat ditafsirkan sebelum pengiriman dilaksanakan. Penelitian ini mengembangkan regresi logistik berbasis dataset terbuka DataCo dengan memperhatikan unit analisis, kebocoran informasi, serta evaluasi temporal. Sebanyak 180.519 baris produk diagregasi menjadi 65.752 pesanan; setelah 2.855 pesanan dibatalkan dikeluarkan, analisis mencakup 62.897 pesanan pada Januari 2015–Januari 2018. Data dibagi secara kronologis menjadi pelatihan 44.027, validasi 9.435, dan pengujian 9.435 pesanan. Regresi logistik berpenalti L2 digunakan karena seluruh pengiriman First Class yang memenuhi kriteria analisis tercatat terlambat. Model memperoleh ROC-AUC 0,7471, average precision 0,8385, dan Brier score 0,1879 pada data uji. Ambang 0,485 yang dipilih pada data validasi menghasilkan sensitivitas 53,95%, spesifisitas 90,49%, dan presisi 88,49%. Analisis sensitivitas tanpa First Class menunjukkan odds ratio Second Class sebesar 6,03 dan Same Day sebesar 1,30 terhadap Standard Class. Namun, model yang hanya menggunakan moda layanan mencapai ROC-AUC 0,7441 dan Brier score 0,1879; tambahan prediktor memberikan peningkatan diskriminasi yang kecil. Temuan menegaskan dominasi konfigurasi janji layanan dalam label keterlambatan DataCo, sekaligus membatasi interpretasi kausal terhadap moda pengiriman. Model layak sebagai dasar penyaringan risiko, tetapi memerlukan validasi eksternal dan informasi operasional yang lebih rinci sebelum implementasi.

Abstract

Short-term photovoltaic forecasting supports operational planning only when point accuracy, predictive uncertainty, and transferability are evaluated together. This study investigates these requirements using the original Solar Power Generation Data repository, containing fifteen-minute records from two Indian photovoltaic plants over 15 May–17 June 2020. A data audit identifies incomplete inverter panels and a tenfold discrepancy in the recorded DC-to-AC ratio. Consequently, forecasts target normalized aggregate AC power exclusively at timestamps with all 22 inverter records. Histogram-based quantile gradient boosting is evaluated at 15-, 30-, and 60-minute horizons under a fixed chronological fit–validation–calibration–test design. Local models, bidirectional transfer without target-plant model fitting, source-calibrated intervals, and target-recalibrated intervals are distinguished explicitly. Across the six transfer experiments, the rearranged median forecast reduces mean absolute error by 5.4–32.3% relative to ordinary persistence, although ridge regression outperforms it in several comparisons. Uncalibrated nominal 90% transfer intervals attain only 79.6–87.0% empirical coverage. Source calibration raises coverage to 85.1–91.7%, while three days of target calibration yield 88.1–94.2%. Increased coverage can require materially wider intervals and does not consistently improve weighted interval scores. Paired day-block bootstrap intervals reveal that two transfer skill estimates remain compatible with no improvement over persistence. The evidence supports a practical distinction between transferring a forecasting function and transferring its uncertainty calibration. For industrial energy planning, the resulting framework offers a transparent assessment of forecast risk, while the short observation period, missing-record selection, and limited plant metadata preclude claims of universal transferability or realized economic savings.
