Abstract

The purpose of this study was to investigate the different environmental factors that influence the growth, productivity, and quality results of harvest sorghum (Sorghum bicolor L.) as material food alternatives and materials raw bioethanol. The study consisted of 3 different treatments, where each treatment produced data to examine its effect on productivity, quality results. The experiment was designed using RAKF (factorial randomized block design) experimental design with one treatment factor, the usage of biofertilizer. The results show that liming at a dose of 2.5 tons/ha (Ca1) is sufficient to cultivate on acid soils with the red-yellow podzolic type and is more optimal if using a dosage of 5 tons per hectare depending on the results of soil analysis before planting. The best sugar quality is produced in the planting treatment during the dry season, with a total sugar value of about 14.5% and the highest reduction sugar of 2.4%. The addition of lime to acidic soil and the application of chemical and biofertileizers are crucial for optimal growth, enhancing both vegetative and generative development when applied in appropriate amounts. Furthermore, exploring the physiological mechanisms behind seasonal impacts on sugar content and assessing the economic viability of different planting seasons will provide valuable guidelines for farmers seeking to maximize food production and bioethanol raw materials.

Abstract

The purpose of this study was to analyze the production costs of cassava farming, the income of cassava farming, and the feasibility of cassava farming in the study area. The research location was determined purposively based on the consideration that the studied area is one of the centers of cassava production of the Cimanggu variety for chips, which is a potential food ingredient in East Lampung Regency, but cassava grown locally by farmers still has low productivity. In order to increase cassava productivity and production, one of the farmers in Jabung Village, Jabung District, East Lampung Regency developed a superior cassava variety, the Cimanggu variety. This study aims to determine revenue, R/C ratio, and constraints of cassava farming of the Cimanggu variety by farmers in Jabung Village, Jabung District, East Lampung Regency. The results of our research using 2024–2025 data show production costs of Rp12,395,366.67 with revenue of Rp56,848,425.00; the results obtained are Rp44,453,058.33 per hectare with an R/C ratio of 3.59, which means that cassava farming is very profitable or feasible to be developed. The technical constraints faced are limited fertilizer, cassava seeds, and white pest attacks. The economic constraint is the low price of wet cassava tubers in the market.
