The business unit's black tea processing of Perkebunan Nusantara suffered a loss of approximately Rp.60 billion. This is caused by the failure to achieve the quality and quantity of production which has been targeted by the management. Black tea processing factory "Pahit Madu" is required to improve the performance of the production process. To improve the production of black tea starts from improved production equipment through improved equipment utilization. One method ofmeasuring the effectiveness of using an apparatus is Overall EquipmentEffectiveness (OEE). OEE calculation results show that black tea factory "Pahit Madu" for four (4) years under the standard. Means, the effectiveness of utilization of equipment in the factory black tea "Pahit Madu" was still very low. This was shown by the low performance equipment in the milling unit, drying unit and sortation unit. Toimprove the performance of the plant should begin by increasing the Cutting Tearing Curling (CTC) machine in milling stations, machines Fluid Bed Dryer (FBD) and Heat Exchanger (HE) at the drying stations, and Winnower machines at the sortation stations.

The contribution of rubber to national economic and social development is important for Indonesia. However, smallholding rubber, the dominant rubber producer, has low productivity. Indonesian government has been introduced various technologies including clonal planting material to increase the productivity increase rubber production and farmers’ incomes. However. This study helped to identify the main reasons, motivations and constraints that influenced a farmer’s decision in Jambi and West Kalimantan to adopt or not adopt clonal rubber by using Focus GroupDiscussion (FGD) method. This study show that the main constraint in adoption for both areas was limitation of capital as the clonal rubber required more capital to establish. The other constraints are risk and uncertainties including pest and disease problems, the shortage of labour, lack of access to clonal seedlings. This study result can be used by Indonesian Government in order to encourage rubber farmers inJambi and West Kalimantan to adopt clonal rubber to increase rubber productivity as well as farmer’s income.
