Abstract

Work productivity is one of the important factors in determining the operational success of oil palm plantation companies, especially in the harvesting section. This study aims to analyze: (1) the effect of work motivation on work productivity; (2) the effect of work ability on work productivity; and (3) the effect of work motivation and work ability simultaneously on the work productivity of harvesters at PTPN IV Regional I Adolina Plantation Afdeling II. This study uses an explanatory research method with a quantitative approach. The research sample consisted of 48 oil palm harvesters selected using a saturated sampling technique. Data were obtained through questionnaires and analyzed using descriptive analysis, validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, t-tests, F-tests, and coefficients of determination (R²) with the help of SPSS version 23. The results of the study indicate that work motivation and work ability simultaneously have a significant effect on work productivity. Partially, work motivation does not have a significant effect on work productivity, while work ability has a positive and significant effect on work productivity. Therefore, the company needs to improve the work ability of harvesters through technical training, job coaching, and periodic evaluations to increase harvester work productivity.

Abstract

This study aims to determine the partial and simultaneous effects of work motivation and work environment on employee performance at PT Perkebunan Nusantara IV Regional II Unit PKS Sosa. This research is a quantitative study applying a survey method with structured questionnaires for data collection. The respondents involved were 58 male employees. Data analysis methods included validity and reliability tests, classical assumption tests, multiple linear regression analysis, and hypothesis testing (t-test and F-test) using SPSS version 23 software. The results showed that partially, work motivation had a significant effect on employee performance with a significance value of 0.018 < 0.05 (t-statistic 2.429). The work environment also significantly affected employeeperformance partially with a significance value of 0.006 < 0.05 (t-statistic 2.888). Simultaneously, work motivation and work environment had a significant effect on employee performance with a significance value of 0.000 < 0.05 (F-statistic 19.651). The coefficient of determination (R2) of 41.7% indicated that both independent variables could explain employee performance variants, while the remaining 58.3% was influenced by other variables outside this research model. Based on the partial test, the work environment was identified as the most dominant variable affecting employee performance at PKS Sosa due to its smaller significance value.

Abstract

This study aims to analyze the quality of human resources (HR) among oil palm farmers, identify factors that hinder HR development, formulate effective HR development strategies, and analyze their impact on improving farmer welfare in Gunung Meriah District, Deli Serdang Regency. The study used a descriptive method with a qualitative approach. The research location was determined purposively in Gunung Meriah District with 69 farmers selected using simple random sampling technique from a population of 221 farmers. Data were collected through semi-structured interviews, field observations, documentation, and literature studies. Data analysis was conducted using a SWOT analysis using the IFAS, EFAS, and SWOT matrices. The results showed that the quality of farmers' HR is still relatively low, characterized by minimal access to training and extension, low technical cultivation skills, and dependence on informal information sources. The main obstacles to HR development come from limited capital and technical knowledge, as well as external factors such as the unavailability of extension programs, poor road infrastructure, and weak farmer institutions. The SWOT analysis places farmer human resource development in Quadrant I (aggressive strategy), indicating significant strengths and opportunities to be exploited. Recommended priority strategies include increasing Good Agricultural Practices (GAP)-based extension services, strengthening farmer groups and cooperatives, expanding access to capital, utilizing information technology, and improving supporting infrastructure. Planned and sustainable human resource development is a key factor in increasing the productivity, competitiveness, and welfare of oil palm farmers in Gunung Meriah District
