    The concept of utilizing a rubber compound sheet (RCS) made from natural materials as a substitute for polymer plastics was investigated. In this study, the functions of RCS as a geomembrane were investigated. Testing on thickness, mass per unit area, tensile strength, and interface shear strength behavior under various environmental conditions or various curing conditions, including air, tap water, and wastewater (acid water (pH 6) and base water (pH 9)) for 90- and 180-curing days, were conducted. It was found that the properties of the RCS geomembrane, such as thickness, mass per unit area, tensile strength, and interface shear strength, were not affected by various curing conditions. The results confirmed that the RCS geomembrane can function as a geomembrane.

    This research developed a natural para rubber from rubber tree sap as a biodegradable-reinforced material in geogrid application with the purpose of membrane support, bearing capacity increment, and lateral restraint in embankment construction. Biaxial geogrids with an aperture size of 20 mm × 20 mm were prepared from the ribbed smoked sheet (RSS) made of the coagulated latex sheets, and rubber compound sheet (RCS) made of chemically modified RSS sheet to increase the rubber performance were investigated and compared. The performance of RSS and RCS was evaluated under the actual situation in a field test with an area of 4.5 m-length x 1 m-width with 0.5 m-depth. In each studied area of the reinforced zone, RSS and RCS were separately inserted at 250 and 450 mm from the base of a field test as the 1st and 2nd reinforcement layers, respectively. The load was applied to simulate the traffic load. The RSS- and RCS-reinforced zones in the field test were compared with the non-reinforced zone in terms of settlement and rut depth. The drastic settlement and rut depth were significantly detected in non-reinforced zones compared to the reinforced zones. Meanwhile, higher settlement and rut depth were observed at RSS-reinforced zones compared to the RCS-reinforced zones. The RCS geogrid in this research was successfully applied as a functional biodegradable-reinforced material for embankment construction.

    Plummeting demand and increasing production have triggered a fall in rubber prices. This may be due to the impact of technological progress that can evolve synthetic raw materials to replace the use of rubber in certain industries. There are a number of reasons that cause the rubber price crisis. Consequences are not only affecting rubber planters, but also causing a direct impact to the overall economy of the country. Various agencies have seriously sought ways to solve the problem to help rubber farmers. One simple and practical method that has been proposed is to grow some other crops in free spaces of rubber plantations. It is an excellent idea to transform a single rubber plantation into an integrated farmland, in which rubber planters will not have to rely only on one source of income. Pursuing the sufficiency economy philosophy, the main objective is to help rubber farmers earn greater incomes in a sustainable manner, particularly by improving the quality and quantity of their crops, while remaining firm in preserving natural resources, such as soil, water, and air. To make such solution achievable, the public and private sectors have conducted various researches on how to produce a greater yield on a given plot of land in a rubber plantation. Certain types of crops have been determined to be grown in rubber plantations. They are compatible crops, multiple crops, and economic crops, which can ensure increasing agricultural productivity throughout the rubber plantation period. This paper aims to present the analysis of data related to the cultivation of other crops in unoccupied areas of rubber plantations, where rubber farmers and relevant parties will be offered productive suggestions on rubber farming. For data that have been input to process in the advisory system such as soil, water, air, and alternative crop prices can be obtained from data online and data offline. The results from the system will be knowledge for rubber famers directly or agricultural specialists to provide rubber farmers with extensive knowledge on the benefits of transforming a single rubber plantation into an integrated farmland, as part of the goal to create greater income-earning opportunities by growing compatible crops, multiple crops, and economic crops.
