Rubber plants are an important plantation commodity as a source of non-oil and gas foreign exchange for Indonesia so they have a bright future. Propagation of rubber plants by grafting depends on the quality of the rootstock, and the graft as well as the grafter. The rootstock for rubber seedlings comes from seeds classified as recalcitrant. They have high moisture content, short shelf life, quickly loose their ability to germinate, and their cells freeze if stored at temperatures below 0oC. This study aimed to extend the shelf life of rubber seeds using a wax coating technique. The study was carried out for 2 months at the Unand campus III laboratory. A completely randomized divided plot design consisting of two factors, namely application of wax layer and shelf life was used. Application of wax slowed rubber seed germination. Various explanations are possible for this observation. One is that the ratio of wax/water in the suspension used to apply the wax layer was not appropriate. The longer the seeds were stored the lower the percentage germination observed. Therefore, further research should be conducted using less than 50% wax in the suspension use to coat the seeds.

Plantation of PT. Tidar Kerinci Agung (PT. TKA) is a company engaged in oil palm plantations with an area of 24,000 ha and has been certified by Indonesia Sustainable Palm Oil (ISPO). PT. TKA has a factory for Crude Palm Oil (CPO) processing, therefore the local community can sell their palm oil yield to the factory. However, the purchase of Fresh Fruit Bunches (FFB) from the community was constrained by the fact that many people use random seeds which reduce the quality of CPO, moreover the agronomic factors such as fertilization, rainfall, plant maintenance and harvesting on smallholder plantations which are the factors that can reduce the quality of CPO. The present study was conducted for 3 months, with the objective was to determine the comparison of the palm oil extraction rate between smallholder plantations and large-scale estate (PT. Tidar Kerinci Agung). The research method was a survey by purposive sampling to obtained data on oil palm production, especially in relation with oil extraction rate. The result showed that the oil extraction rate of CPO was 24.51% and it’s on Palm Kernel Oil (PKO) was 4.45% in large-scale estate (PT. TKA). It was higher than the oil extraction rate on smallholder plantations. The oil extraction rate of CPO and PKO in the high yielding, moderate yielding, and low-yielding smallholder plantations were CPO 20.55% and PKO 4.42%, CPO 21.50% and PKO 3.77%, and CPO 18.35% and PKO 4.34%, respectively.
