Abstract

Soil is an essential factor in cultivating plants, which, apart from being a planting medium, also supplies food in the form of nutrients. For successful cultivation, farmers should know the condition of the soil before planting. One of the most important things is the soil acidity level (pH) and the type of soil that will be used for planting. The research aimed to determine the effect of soil processing and liming on the growth and production of red bean plants. The research was carried out in Bontomanai Village, Bungaya District, Gowa Regency, at an altitude of ± 400 meters above sea level from May to December 2023. The research used a Factorial Randomized Block Design with 2 factors. The first factor is soil processing, with 2 treatment levels: No tillage (control) and tillage (Hoeing). The second factor is the lime dose, with 4 levels of treatment, namely without liming (control), 1 ton/ha (0.1 kg/plot), 2 tons/ha (0.2 kg/plot), 3 tons/ha (0 .3 kg/plot). There were 8 combinations, and each treatment combination was repeated 3 times, so that 24 treatment combination units were obtained. Each treatment combination unit used 10 plants and 3 sample plants. The research results showed that tillage had a better effect than no tillage at a weight parameter of 100, namely 41.30 gr. Liming at a dose of 3 tons per hectare had the best effect on plant height parameters, namely 47.68 cm. The interaction between soil processing and liming at a dose of 3 tons/ha gave the best effect on seed weight per planting, 24.93 grams, seed weight per plot of 0.28 kg, and seed production per hectare, namely 2.8 tons/ha.

Abstract

The agricultural sector is vital economic growth; one is by processing agricultural products into valuable products, such as tempeh, from raw soybean materials. The research aims to 1) Describe the characteristics of sellers and buyers of tempeh; 2) Describe the amount of tempeh sold by traders and the amount purchased by consumers; 3) Analyze the factors that affect the demand for tempeh; and 4) Analyze the factors that affect the supply of tempeh. The research was conducted in Pa'baeng-Baeng Market and Terong Market in Makassar City, South Sulawesi. The sample of tempeh traders was 50 people, and the sample of buyers was 200. The analysis methods used were descriptive analysis and multiple linear regression analysis. The results showed that the characteristics of tempeh buyer respondents were 40 years old on average, the average education level was high school (56.82%), the most female gender (83.64%), and predominantly worked as housewives (46.81%). The characteristics of tempeh trader respondents based on age are an average of 41 years, an average high school education level, and the dominant gender is male (74.00%). The average tempeh purchased by consumers is 19 packs/month, and the average tempeh sold is 3,504 packs/month. Simultaneously (F-test) is significant to the demand for tempeh, with a coefficient of determination (R2) of 62.1% that have a significant effect partially (T-test) are all the variables tested, namely the price of tempeh, buyer income, number of family dependents, intensity of need, taste, and price of substitute goods. F-test is significant to the supply of tempeh, with a coefficient of determination (R2) of 60.3%. The significant factor of effect partially (t-test) on the supply of tempeh are the price at the producer level, future price expectations, the number of producers, and the number of consumers. Meanwhile, the price at the trader level is insignificant
