Soybean is one of the national strategic commodities. The increasing of soybeans needs, it is necessary to prepare the high quality seed. Different environmental conditions such as soil condition and cropping system will affect the quality of seed. The aimed of this study was to investigates the quality of soybean seed from different types of soil and cropping system. The research was conducted experimentally using Randomized Block Design (RBD) with two factors. The first factor is the source of seeds that come from two types of soil, namely peat and mineral. The second factor is seeds that come from monoculture and intercropping. Based on the results of the study, it showed that the fat and protein content of soybean seeds from seeds planted on mineral soils was better than seeds from peat soils. Planting soybean seeds in peat soil can increase the fiber and carbohydrate content of the seeds as well as the viability and vigor of the seeds. Intercropping system increased protein and fiber content of seed, but not affect its vegetative growth.

Damage to land caused by conventional farming, as a result of the use of synthetic fertilizers and pesticides, threatens future food availability. Organic farming is considered one of the efforts to implement sustainable agriculture. Consumer preferences need to be directed towards consuming organic agricultural products, but there are still many other factors influencing this behavior. Numerous studies have been conducted to assess consumer behavior. Some of these studies use the Theory of Planned Behavior (TPB) model to determine whether or not a specific behavior is performed. The Theory of Planned Behavior (TPB) model still needs to be integrated with other factors that also influence the adoption of a particular behavior. This study aims to propose an alternative model based on the Theory of Planned Behavior (TPB) to understand consumer behavioral intentions regarding the consumption of organic food. A descriptive method with a systematic review approach was used in this study based on a review of articles related to consumer behavior in the organic food domain. An alternative model of the Theory of Planned Behavior (TPB), with several additional influencing factors such as Religiosity, Health Consciousness, Environmental Consciousness, Price Barrier, Trust, Availability, and Knowledge, is provided as input for researchers, practitioners, and policy makers.
