The “dish system” for calculating wages in rice farming in Majalengka District, West Java Province
No full textFarmers play an important role in the agricultural sector; however, their welfare does not always increase with growth in this sector. Rice farming is generally affected by local customs and traditions, and labour costs are the largest expense. Local knowledge offers a distinctive feature in rice farming, such as the “dish system” in Majalengka District, where labourers are paid in bawon, a tradition in rice farming. However, this tradition may not always be economically beneficial to farmers. This study aims to identify the dish system of local wisdom in rice farming, analyse its economic efficiency, and compare the profit level with farming in general. Primary data were collected by conducting interviews with 65 farmers. The study revealed that the use of a dish system for wages results in greater profits and a higher R/C ratio value compared to daily wages in general. When using the bawon method, it is important to maintain socially adhered values because increasing farmers’ income and welfare is also a priority for the sustainability of rice farming. This study suggests taking comprehensive steps, such as strengthening existing farmer institutions, providing training and empowerment for farmers, and maximising profits through agricultural businesses

CHARACTERISTICS AND ANALYSIS OF SHALLOTS FARMING IN DOLOK SILAU SIMALUNGUN, NORTH SUMATRA
Full text linkThe purpose of this study is to determine the characteristics of shallot cultivation and to understand the financial feasibility analysis in Dolok Silau Simalungun to enhance the improvement of the technology needed. Methods used in this research are survey and observation methods. Based on the assessment results, it was found that shallot farming which is planted on dry land and small scale in Sarang Padang, Dolok Silau, Simalungun has a 0,05 – 0,1 ha area. The productivity of that farming is low which averaging 5,25 tonnes/ha. The total production cost is Rp 59.598.000 with a B/C ratio of 0,59. The capital of shallot production is Rp 10.743,00 per kg. Most of the shallot production cost is absorbed by labor cost (36 %), followed by seed cost (35%). The increment of revenue can be achieved by improving productivity through the improvement of farming technologies. Technology improvements in shallot cultivation that are needed are increasing plant density, seed quality improvement, replacement of labor weeding, and the use of integrated pest and disease control. To anticipate price fluctuations, farmers need a storage technology that is a group warehouse to keep the shallot when the market price is very cheap. Institutional education needs to be strengthened for the socialization of shallot cultivation technology and innovation for the farmers
