Abstract

There are many factors influencing work morale, including organizational climate, work environment, work discipline, leadership, commitment, compensation, career development, and promotion and so on. However, this research only examines the factors of work discipline, commitment and organizational climate. This study aims at determining the effect of work discipline, commitment and organizational climate partially and simultaneously on the morale of employees of the Regional Property Management of the Dairi Regency Government. The population of this research is 48 employees. In determining the number of samples, saturated samples are used so that the sample is 48 employees. Data collection techniques in this study are questionnaires, interviews and documentation studies. While the data analysis techniques used are the classical assumption test, multiple regression, partial test, simultaneous test and the coefficient of determination. The results show that the work discipline variable has an effect on the morale of employees at the Regional Property Management of the Dairi Regency Government, where the better work discipline, the higher the morale will also be. The commitment variable has a significant effect on the morale of employees at the Regional Property Management of the Dairi Regency Government, where the better the work commitment, the higher the morale will also be. Organizational climate has a significant effect on the morale of employees at the Regional Property Management of the Dairi Regency Government, where the better the organizational climate, the higher the morale will be. Simultaneously, there is a significant influence on the influence of discipline, commitment, and organizational climate on employee morale. It is recommended that the Head of the Regional Property Management of the Dairi Regency Government should provide an example and provide disciplinary sanctions according to violations committed by subordinates, encourage employee involvement in solving every problem, and provide strong encouragement so that employees commit to work.

Abstract

Productivity can be influenced by many factors, including work discipline, training, work motivation, job promotion; human resource development and work ability but the most important factors are promotion, development of human resources and work ability. This study aims at finding the effect of job promotion, human resource development and work ability partially and simultaneously on the work productivity of employees at Hotel Danau Toba International Medan. The population of this research is 600 workers. To determine the number of samples, the Slovin formula was used so that the sample is 86 workers. Data collection techniques in this study are questionnaires, interviews and documentation studies while the data analysis technique used is the classical assumption test, multiple regressions, t test, F test and the coefficient of determination. The results show that the job promotion variable has a significant effect on work productivity at the Danau Toba International Medan Hotel, where the better the promotion, the higher the employee's work productivity. HR development variables have a significant effect on work productivity at the Danau Toba International Hotel Medan, where the better the HR development, the higher the employee's work productivity. The work ability variable has a significant effect on work productivity at the Danau Toba International Medan Hotel, where the better the work ability, the higher the employee's work productivity. Simultaneously there is a significant influence on job promotion variables, HR development and work ability. It is suggested that hotels need to carry out job promotions based on work competence and work performance, so that employees who have high work abilities and performance are prioritized for promotion. Hotels need to adapt the development program to the long-term development plan, and determine development program participants based on the potential of individual employees' abilities. Hotels need to place employees according to their educational background and work experience.

Abstract

Screw press berfungsi sebagai pemisah minyak dari daging buah atau yang disebut dengan proses pengepresan, apabila mesin tersebut mengalami kerusakan, maka akan menyebabkan terhambatnya proses produksi dan menyebabkan kerugian bagi perusahaan, kerusakan pada Screw press erat kaitannya dengan perawatan. jika perawatan tidak dilaksanakan dengan baik, akan menyebabkan kerusakan pada mesin tesebut. Untuk mengidentifikasi kerusakan dan tindakan perawatan yang tepat digunakan dengan metode FMEA sehingga diketahui kegagalan komponen kritis pada suatu sistem berdasarkan nilai Risk Priority Number (RPN) yang diperoleh. Bedasarkan hasil penelitian dengan menggunakan metode tersebut, diketahui komponen yang rusak dan nilai RPN tertinggi hingga terendah yaitu, Press Cage dengan nilai 384, Double screw 360 RPN, Bearing 144 RPN, Cone dengan nilai RPN 60, Oil Seal 54 RPN dan V- belt dengan nilai RPN 48. Untuk tindakan perawatan yang dilakukan dalam meminimalisir kerusakan tersebut, dilakukan dengan tindakan perawatan prediktif yang merupakan kegiatan perawatan dalam mengantisipasi kegagalan sebelum terjadi kerusakan total dan tindakan korektif yang merupakam kegiatan perawatan yang dilakukan ketika komponen mengalami kerusakan .

Abstract

The first stage of this research was to make polystyrene grafted with maleic anhydride for making the couping agent with other filling compound. In the second stage, the polystyrene matrix grafted with maleic anhydride was combined with filler material derived from palm oil mill waste using the dry mixing method with an internal mixer. Among several variables tested, the optimum composition of the polymer composite was found to be Polystyrene grafted with maleic anhydride: sludge: boiler ash in a ratio of 60:25:15. This composition exhibited a Young's modulus of 856.752 MPa, a tensile strength of 6.057 MPa, and an elongation at break of 0.775%. Differential Scanning Calorimetry (DSC) testing revealed a glass transition temperature of 403.22°C, a crystallization temperature of 426.39°C, and a cross-linking indication temperature of 478.64°C. Scanning Electron Microscopy (SEM) tests showed an even distribution of the material. Fourier-transform infrared (FT-IR) spectroscopy indicated a decrease in absorption peaks at 3024.94 cm⁻¹ and 3025.15 cm⁻¹, while the polystyrene characteristics at the wave number 1600.57 cm⁻¹ appeared sharper. The sound absorption test results met the ISO 11654:1997 standard for the rating level of sound absorption coefficient in materials, achieving Class D and C sound absorption with an αₙₓ value ranging from 0.328 to 0.793.
