Abstract

Indonesia is one of the largest tea producing countries where dry tea production is exported to various countries. The tea industry absorbs a lot of labor both from the area around the tea garden and from outside the garden area. Tea pickers are workers who really need their existence, considering the quality and quantity of tea depends on how they work. The wages of tea pickers are very low due to the small amount of picking weight produced because the picking system is still done manually. The purpose of this study was to determine the effect of manual picking mechanization and using scissors on the wages earned by pickers. Sampling was done randomly and analyzed using multiple linear regression. The results showed that there was a significant difference between the picking system and the wages of the pickers. The use of picking scissors can increase wages by 40.18%. The increase in pickers' income is expected to be able to motivate pickers to work optimally to increase the welfare of Wonosobo tea pickers.

Abstract

Productivity is a comparison between the results achieved (output) with the overall required resources (input) or a comparison between the results achieved with the role of labor per unit time. The purpose of this study was to study Down Time analysis techniques for productivity in a wheat processing company (PT. Eastern Pearl Flour Mills Makassar), which produces wheat flour products of the Gatotkaca, Gunung, Kompas and Gerbang types. Down Time is the amount of time when a tool/machine cannot operate due to failure, but the factory can still operate because there are still other tools/machines that can replace functions so that the production process can still run. Based on the data analysis of the calculation of down time for manpower, it shows that the existence of down time during the process will affect the level of productivity (actual and standard). The value of down time from the calculation of working hours minus work effectiveness results in down time for each production area each month. The manpower down time results from all areas, namely in the area of 0 minutes/month. While the amount of data from the analysis of down time calculations for machines in all areas has a higher number of machine down times, namely in the milling area of 28 hours. And for the lowest results, namely in the area of unloading, cleaning, and packing, it is 0 hours.

Abstract

One factor affecting productivity is the quality of seeds with good initial seed vigor indicators, but less than optimum growing environment conditions also affect seeds' growth and initial Vigor. One of the technologies that can improve it is giving priming treatment to the seeds before planting. This study aims to see the effect of priming treatment to improve the quality of Vigor and early growth of 2 composite corn varieties, namely Sukmaraga and Bisma. The research was carried out in the laboratory and the Green House, with the experimental method using a Completely Randomized Design (CRD) with each seed of the two varieties treated with Hydropriming (soaking seeds before planting) using Ion-Free Water (IFW) for 30 minutes, 12 hours, and 24 hours plus a control treatment without Priming, and priming using PGR made from sodium orthonitrifenol 0.2%, sodium 2,4-dinitrophenol 0.05% both as controls. So there are a total of 10 treatments. The results showed that priming treatment greatly influenced the germination, where all Hydropriming treatments gave average germination above 88%, significantly different from seeds without priming below 82%. The hypocotyl length ratio of Sukmaraga and Bisma corn seeds was also different from the treatment without priming. Seeds with hydropriming for 12 hours showed the best field growth percentage, reaching 96.7% (Sukmaraga variety) and 96.98% (Bisma variety).
