This study aims to determine To analyze the effect and efficiency of the use of factors of production such as land, labor, seed, fertilizer Urea, SP36, KCl fertilizers and herbicides Gramaxone on hybrid corn production. in the Sugih Waras village Muara Sugihan District Banyuasin Regency. The method used is the method of a survey of corn growers in the Sugih Waras village Muara Sugihan District Banyuasin Regency. Sampling method is done using a random method (simple random sampling) using the formula Slovin. The number of members of the population of hybrid corn farmer in the village of 168 on the Sugih Waras then the amount calculated into the formula Slovin with a confidence level of 85%, 85% confident that the true and the research results with significance level of , then a sample of the entire population of hybrid maize farmers which can be taken are 35 farmers. Data processing method is the method of interview data collected in this study included primary data and secondary data. Primary data obtained from respondents through direct interviews and field observations accompanied by a list of questions has been provided while secondary data obtained from the competent institutions or agencies associated with this research. Data were processed using mathematical models and presented in tabular form. The results showed that the factors of production labor, urea, fertilizers and herbicides Gramaxone SP36 no significant effect on the production of hybrid corn. While the seeds, area of land and fertilizer KCl significant effect on the production of hybrid corn. Based on the level of inefficiency of production factors such as labor, land, urea and herbicides Gramaxone inefficient that need to be reduced in order to achieve an efficient level. While the factors of production seed, fertilizer KCl, and SP36 has not been so efficient that need to be added to reach the level of inefficiency.
Kata croup berasal dari kata kerja Bahasa Inggris Modern Awal croup, yang berarti "menangis dengan suara parau"; nama ini pertama kali digunakan untuk penyakit ini di Skotlandia dan menjadi populer pada abad ke 18.  Croup difteritik telah dikenal sejak zaman Yunani Kuno Homer . Pada tahun 1826, Bretonneau membedakan antara croup virus dengan croup akibat difteri .  Orang Perancis menyebut croup viral "faux-croup," dan menggunakan istilah "croup" untuk penyakit yang disebabkan oleh kuman difteri.  Croup akibat difteri kini hampir tidak dikenal karena adanya imunisasiyang efektif.
