Abstract

The existence of weeds on agricultural land causes competition with cultivated plants in obtaining nutrients, water, and sunlight. Therefore, it is necessary to carry out weed control so as not to interfere with the growth and development of cultivated plants. This study aims to find out the types of weeds that grow in the disc area and to find out the most effective herbicides based on the content of active ingredients in controlling weeds in the oil palm disc area. Sampling was carried out by purposive sampling technique. Based on this technique, 2 blocks were obtained as research locations, namely block 73B and block 68A with a sample area of 351 m2 in each block. In this area, 9 sample plots were made with the size of each plot 1 m x 1 m. The object of the study was in the form of weeds in the sample plots that were given different treatments, namely using a single herbicide using a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate with a dose of 2 liters/ha in block 73B and a mixed herbicide consisting of a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate + Mitsufuron herbicide with the active ingredient methyl metsulfuron + agristick with the active ingredient alkyllaril polyglycol ether with a dose of 2 liters/ha + 0 each, 075 gr/ha + 0.1 liters/ha in block 68A. The results showed that the types of weeds that grew in the oil palm disk area were broad-leaved weeds such as Ageratum conyzoides, Asystasia intrusa, Clidemia hirta, Phyllanthus urinaria and narrow-leaved weeds such as Setaria plicata. Based on the content of the active ingredient, the most effective herbicide in controlling weeds in the oil palm disc area is a mixed herbicide because it is able to kill weeds completely (100%) on the 15th day after the herbicide application.

The aim of the research is to assess the physical working environmental conditions of harvest work at PT. Alam Jaya Persada in Afdeling 2 and 3, knowing the performance of harvest employees, analyzing the relationship between the work environment and the performance of harvest employees in Afdeling 2 and 3. Quantitative method, the data used is direct observation data in the field, questionnaire data and is equipped with company data or documents as well as literature studies obtained from the internet. The research results show that the physical work environment at PT. Alam Jaya Persada is in good condition, as seen from the average employee response score on topographic indicators of 3.9, humidity and temperature of 3.7, cleanliness of the workplace of 3.8, work tools of 4.1, work facilities of 3. .9 means the whole category is good. Performance of harvest employees at PT. Alam Jaya Persada is good, as can be seen from the average employee response score on the quantity, quality and efficiency indicators of 4.2, work discipline of 4.1, all the average score results are good, and have a significant relationship between the physical work environment and performance with a significance value of 0.001 <0.05. A correlation coefficient of 0.413 means that the relationship is quite strong between the work environment and employee performance and is positive, which means that the relationship between the two variables is in the same direction, where the better the physical work environment, the better the employee's performance.
