Indonesia is the second largest natural rubber producer, which it gets primarily from smallholders. However, smallholders are less and less competitive because of unsustainable agricultural practices, while there is huge potential for sustainable natural rubber. This study aimed to measure the effect of income and smallholder characteristics on cultivation, harvesting, and post-harvest management. Mixed methods with non-probability sampling were used for 100 natural rubber smallholders in Kapuas Hulu Regency, West Kalimantan, Indonesia, one of the regional centers of Indonesian natural rubber. Partial least square path modeling was used with SmartPLS software to estimate the complex cause-effect relationships of smallholder and farm factors for adopting sustainable agricultural practices. The effect of the relationship between income and smallholder characteristics on cultivation and income on post-harvest management was not significant. Age and education affected some harvesting parameters, such as tapping knives, bamboo and clean latex collection, and latex stimulus risk, and some post-harvest parameters, such as a risk of acid coagulation and storage. The worker's income source, based on off-farm, on-farm, or non-farm activities, affected harvesting parameters, including tapping knives, bamboo and clean latex collection, and latex stimulus risk.   This study offers empirical evidence for sustainable agriculture management. The acceptance of sustainable cultivation and management of rubber practices uses smallholder and farm factors as constraints since they do not form a homogenous group, and the theory of planned behavior failed to provide an effective way to explain the behaviors. Good agricultural practices must be used at all steps, including cultivation, harvesting, and post-harvest management, to prevent problems.

Strawberries have a very thin layer coating that easily disappears and are perishables a lot pre-harvest as such nearly 30 to 40 percent of strawberry fruits will be wasted at interval between harvest and consumption. In this study have been investigated the effect of using psyllium mucilage (Plantago psyllium) in concentrations of 6.25, 12.5 and 25 ml/l as well as Arabic gum and Arjan as edible coating in amounts of 0.5, 1 and 1.5 g/l on post-harvest life and quality of strawberry. Strawberry fruits of Kurdistan’ type were immersed after preparing by above solution and then placed in containers PE at 4 ° C and on days 0, 2, 4, 6, 9 and 12 days after storage were measured their quality traits such as pH, anthocyanin, fresh weight, acidity, TSS, wrinkles. The results showed that fruits treated with 12.5 ml per liter psyllium mucilage had the highest rates of water and after treatments for Arabic gum0.5, Arjan 1, and 1.5 grams per liter and psyllium mucilage 25 ml per liter also showed a significant effect on retention of water. The conclusion after examined the quality of the fruit was that, gum treatments for Arjan 1 and 1.5 grams per liter, had the best quality fruit.
