PENTINGNYA BUDAYA KERJA TERHADAP MOTIVASI KERJA DALAM MENINGKATKAN KINERJA KARYAWAN
Get PDFguidelines for performing tasks. In the era of global competition, a strong organizational culture is believed to enhance work motivation and improve employee performance. This article aims to analyze the importance of work culture on motivation in improving employee performance. The study employs a systematic literature review approach, drawing upon the latest scholarly publications from 2022 to 2025. Findings indicate that work culture serves as an internal organizational factor that fosters positive behavior, a sense of belonging, and stronger employee commitment. Work motivation, both intrinsic and extrinsic, acts as a crucial mediator between work culture and performance. Employees working in organizations with a healthy, collaborative, and reward-based culture tend to show higher motivation, which translates into better productivity, work quality, and innovation. The article also highlights the importance of managerial support, effective communication, and reinforcement of organizational values to sustain a positive work culture. In conclusion, work culture not only directly influences performance but also indirectly through increased motivation

Estimasi Daya Keluaran Fotovoltaik Menggunakan Algortima Genetik
Get PDFThe development of renewable energy systems is a major focus in efforts to reduce environmental impacts and dependence on fossil energy sources. One promising renewable energy source is solar energy, which can be utilized through photovoltaic technology. However, to increase the efficiency of the photovoltaic system, an accurate estimate of the output power produced is required. This study aims to develop a photovoltaic output power estimation model using MATLAB-based Genetic Algorithm (GA). Genetic Algorithm was chosen because of its ability to find optimal solutions to a problem using the principles of natural selection. In this study, parameters that affect the performance of the photovoltaic system, such as sunlight intensity, cell temperature, and panel tilt angle, will be analyzed and modeled. The results of this photovoltaic output power estimation model are expected to provide more accurate predictions, so that they can be used for decision making in the planning and development of solar energy systems. Through simulation and data analysis, this study is expected to make a significant contribution to the development of photovoltaic technology in Indonesia and increase the efficiency of its use.

A Web-Based Machine Learning Approach for Standardized Precipitation Index Prediction
Get PDFAccurate and user-friendly drought forecasting tools are crucial for mitigating the impact of meteorological droughts, particularly in vulnerable areas such as South Sumatra, Indonesia. This study introduces an interactive web-based application built to anticipate drought conditions by forecasting the Standardized Precipitation Index (SPI). The system relies on deep learning techniques trained using three decades of rainfall data collected from the Climatological Station in South Sumatra. In evaluating model performance, both Recurrent Neural Network (RNN) and Long Short-Term Memory (LSTM) architectures were assessed. While both models delivered comparable short-term predictions, the LSTM experienced a significant decline in accuracy over extended forecasting periods (specifically at SPI-6), primarily due to overfitting. In contrast, the RNN displayed more stable and reliable results, making it the preferable model for this geographical context. Specifically, the RNN achieved a lower Mean Absolute Error (MAE) of 0.4007, a reduced Root Mean Squared Error (RMSE) of 0.4684, and a higher coefficient of determination (RΒ²) of 0.7338. These metrics outperformed those of the LSTM, which recorded a MAE of 0.4115, an RMSE of 0.4840, and an RΒ² of 0.7036. Such results confirm that the RNN offers a more precise and dependable fit for the stationβs dataset. The web platform also effectively visualizes the model outputs, providing a dynamic and interactive 24-month forecast view that supports early warning efforts and informed decision-making for regional authorities and stakeholders

PENGARUH GREEN PROCESS INNOVATION, GREEN PRODUCT INNOVATION DAN ENVIRONMENTAL PERFORMANCE TERHADAP KINERJA KEUANGAN DENGAN AKUNTANSI MANAJEMEN LINGKUNGAN SEBAGAI VARIABEL INTERVENING PADA PERUSAHAAN SEKTOR MAKANAN DAN MINUMAN YANG TERDAFTAR DI BURSA EF
Get PDFThis quantitative study investigated the influence of green process innovation, green product innovation, and environmental performance on financial performance, with environmental management accounting (EMA) acting as an intervening variable. Focusing on 12 food and beverage companies listed on the Indonesia Stock Exchange from 2019 to 2023, the research analyzed secondary data from annual reports using SmartPLS 4. The analysis, encompassing outer and inner model testing, revealed that green process innovation and environmental performance directly and significantly impacted financial performance, while green product innovation did not show a significant direct effect. Furthermore, when EMA was considered, green process and product innovation had no significant indirect effect on financial performance. However, environmental performance did significantly influence financial performance through EMA. Finally, the study confirmed EMA's significant positive impact on financial performance
Analisis Kinerja Layanan Kapal Ferry Penumpang Samosir Menggunakan Metode Importance Performance Analysis
Get PDFTransportasi penyeberangan menggunakan kapal ferry merupakan moda utama untuk mencapai Pulau Samosir melalui berbagai pelabuhan di Danau Toba. Penelitian ini bertujuan untuk menganalisis tingkat kinerja (performance) pelayanan dan tingkat kepentingan (importance) penumpang kapal ferry di Pulau Samosir menggunakan metode Importance Performance Analysis (IPA) dan Customer Satisfaction Index (CSI). Pendekatan yang digunakan bersifat kuantitatif dengan pengumpulan data melalui survei terhadap 1.081 responden dari enam kapal ferry pada tiga rute: TigarasβSimanindo, AjibataβTomok, dan AjibataβAmbarita. Kuesioner disusun berdasarkan standar pelayanan minimum sesuai Peraturan Menteri Perhubungan No. 62 Tahun 2019, dengan skala Likert sebagai alat ukur. Hasil penelitian menunjukkan adanya ketidaksesuaian antara harapan dan persepsi penumpang terhadap layanan yang diberikan. Lima dari enam kapal menunjukkan tingkat kinerja yang lebih rendah dibanding tingkat kepentingan, mengindikasikan ketidakpuasan. Nilai ketidakpuasan tertinggi diperoleh KMP Pora-Pora (3,98), diikuti oleh KMP Ihan Batak (3,90), KMP Sumut 1 (3,80), KMP Sumut 2 (3,79), dan KMP Tao Toba 2 (3,79). Hasil ini menunjukkan perlunya peningkatan layanan berdasarkan prioritas atribut yang belum memenuhi ekspektasi penumpang

Get PDFThe objective of this study was to determine the effect of using Indonesian-language instructional videos on the listening skills of fourth-grade students at SD Negeri 030279 Sidikalang in the 2024/2025 academic year. This study employed a quasi-experimental method with a pretest-posttest control group design. The sample consisted of one class comprising 22 students. Data were collected using 10 multiple-choice questions, 5 short-answer questions, and observations. The results of data analysis showed a significant improvement in listening skills after using the Indonesian-language instructional videos, with the average pretest score of 33.40 increasing to a posttest score of 77.95. Statistical analysis using the paired sample t-test revealed a significant difference between the pretest and posttest scores, with a significance value (p-value) of 0.000 < 0.05. The calculated t-value was 7.240, which was greater than the t-table value of 2.012. Thus, the hypothesis testing results indicated that the alternative hypothesis (H1) was accepted and the null hypothesis (H) was rejected. These findings indicate that the use of Indonesian-language instructional videos has a positive effect on improving the listening skills of fourth-grade students at SD Negeri 030279 Sidikalang
