Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh gaya kepemimpinan, lingkungan kerja, dan disiplin kerja terhadap kinerja karyawan di PT. Wana Sawit Subur Lestari Surabaya. Metode yang digunakan adalah kuantitatif dengan pendekatan survei, serta analisis data dilakukan melalui uji regresi linier berganda, serta pengujian menggunakan SPSS 21. uji t (parsial), dan uji F (simultan). Sampel dalam penelitian ini berjumlah 52 responden karyawan. Hasil uji regresi linier berganda menunjukkan bahwa gaya kepemimpinan (X1) memiliki pengaruh yang tidak signifikan, sedangkan lingkungan kerja (X2) dan disiplin kerja (X3) berpengaruh positif terhadap kinerja karyawan (Y). Hasil uji t menunjukkan bahwa hanya variabel lingkungan kerja (t = 8,071; Sig. = 0,000) dan disiplin kerja (t = 3,791; Sig. = 0,000) yang berpengaruh signifikan terhadap kinerja karyawan, sedangkan gaya kepemimpinan (t = -0,942; Sig. = 0,351) tidak menunjukkan pengaruh yang signifikan secara parsial. Selain itu, Hasil uji F menghasilkan nilai F-hitung sebesar 45,366 dengan signifikansi 0,000, yang menunjukkan bahwa secara simultan ketiga variabel independen berpengaruh signifikan terhadap kinerja karyawan. Koefisien determinasi (R²) sebesar 0,739 menunjukkan bahwa 73,9% variasi dalam kinerja karyawan dapat dijelaskan oleh gaya kepemimpinan, lingkungan kerja, dan disiplin kerja. Berdasarkan temuan ini, perusahaan disarankan untuk lebih memfokuskan peningkatan kualitas lingkungan kerja dan penegakan disiplin kerja. Di sisi lain, meskipun gaya kepemimpinan tidak berpengaruh signifikan secara parsial, namun tetap perlu dievaluasi dan disesuaikan agar mendukung sinergi dalam meningkatkan kinerja secara keseluruhan

Abstract

Phytochemical screening is a preliminary stage in phytochemical research which aims to provide an overview of class compounds contained in the plants. The solvents used in this study consisted of distillated water, methanol, and n-hexane solvent. The purpose of this study was to determine the secondary metabolites in Red Lemongrass (Cymbopogon nardus (L.) Rendl.) extract using different three solvents. Red Lemongrass extract was prepared by maceration method using distillated water, methanol, and n-hexane (10 gram: 100 mL) as solvents. Results of the extract were subjected to a phytochemical screening test consisting of flavonoids, alkaloids, saponins, tannins, and triterpenoids. The results of phytochemical screening showed that alkaloids, flavonoids, triterpenoids, and saponins were drawn attracted to the distillated water solvent. Meanwhile flavonoids and triterpenoids were drawn to methanol solvents. In addition, triterpenoids were drawn to n-hexane solvents. The best solvent on maceration results will be used as a reference for testing the ability of the extract as an antidiabetic agent.

Abstract

This study aims to examine the effect of Work Environment, Self-Concept, and Organizational Commitment on Employee Job Satisfaction. The population in this study were employees of PT MATU Pasuruan, East Java, Indonesia, with a saturated sampling of 52 employees. Data analysis used SPSS 23 program, with instrument testing namely validity and reliability, classical assumption test, and hypothesis testing. The results of this study indicate that the work environment, self-concept and organizational commitment have a significant effect both individually and simultaneously on employee job satisfaction. Organizational commitment is the variable with the most dominant influence. From the findings, organizations and managers are expected to focus on developing a work environment for their workers in various ways, e.g.: equipping tools, creating comfort and stability. This includes recognizing workers' contributions, communicating company progress and achievements to workers, empowering workers, providing work-life balance, and the knowledge and skills required for optimal achievement. Improving all of these factors can increase the worker's self- concept and commitment in the organization which leads to job satisfaction. This research enriches information/theory regarding the relationship between work environment, self-concept and organizational commitment on employee job satisfaction

Abstract

Penelitian ini berjudul “Analisis External Leak pada komponen Differential HD785-7 di PT BUMA (BRC)”, yang bertujuan untuk mengetahui penyebab terjadinya external leak pada komponen differential Komatsu HD785-7 dan mengetahui tindakan yang tepat untuk mencegah terjadinya external leak. Metode analisis yang digunakan meliputi analisis visual, analisis trend, dimension inspection, dan perbandingan dengan standard pabrik. Berdasarkan hasil analisis trend, terjadi 14 kali kejadian kebocoran eksternal pada differential diseluruh job site PT BUMA. Hasil analisis visual, ditemukan kebocoran pada seal oil. Hasil dimension inspection pada komponen coupling differential, ditemukan bahwa coupling mengalami keausan di bagian sisi distance coupling dan tidak terdapat pengukuran dimensi coupling terhadap ukuran standard dari pabrik di QA sheet BRC. Dari penelitian ini menunjukkan bahwa penyebab terjadinya external leak, karena keausan dari bagian coupling differential yang diakibatkan pemakaian berulang /part reuse yang dilakukan secara berkelanjutan.

Abstract

This article discusses Kenneth Branagh's film Murder on the Orient Express (2017) through John G. Cawelti's popular formula theory, particularly in the context of the mystery genre. This study aims to examine how the narrative structure typical of the detective genre—consisting of the stages of crime, investigation, and resolution—is adapted in the medium of film. By utilizing Cawelti's theory, which emphasizes the combination of convention and innovation, this analysis shows that the film retains the main elements of the mystery formula while introducing aesthetic and moral variations that reflect contemporary values. The use of cinematic techniques such as temporal manipulation, limited perspective, and mise-en-scène enhances the audience's experience in following the investigation. Additionally, the film's theme of alternative justice adds a complex ethical dimension to Agatha Christie's classic narrative. This study confirms that Murder on the Orient Express is not merely a passive adaptation but a critical and relevant reinterpretation of the genre formula within the context of modern popular culture.
