Abstract

Rubber latex is a raw material for Indonesia's strategic plantations and is the largest contributor to the country's foreign exchange after palm oil. Several places in Indonesia have land conditions that are suitable for rubber plantations, one of which is the rubber plantation owned by Perumda Perkebunan Kahyangan Jember. However, in recent years, income from Perumda Perkebunan Kahyangan Jember has continued to decline, so it is necessary to formulate an optimization strategy which is expected to have a positive impact and be able to increase rubber latex production in Perumda Perkebunan Kahyangan Jember. This research uses SWOT and QSPM analysis methods. The results of the research show that there are several factors that influence rubber latex production, both internal and external factors, from these factors several alternative strategies have been produced, including the use of protective umbrellas, producing high quality rubber raw materials, improving production facilities and infrastructure, optimizing technology. for production and promotion. A suitable strategy to be implemented at Perumda Perkebunan Kahyangan Jember is the use of protective umbrellas because the application is quite simple and can function to maintain the quality of production and the quality of rubber latex..

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of the world's important commodities as a producer of vegetable oil needed by various industries. Leaf area index is one of the indicators of plant growth seen from the size of the leaf surface area that carries out the photosynthesis process. This study aims to determine the interaction of NPK Phonska fertilizer dose treatment and its application method on the Leaf Area Index of oil palm seedlings at the pre-nursery stage. The study was designed using factorial RAK consisting of 2 factors, namely the dose of NPK Phonska fertilizer (K) and its application method (A), and 3 replications. The K factor consists of 5 levels, namely K0 = 0 g/seedling; K1 = 0.5 g/seedling, K2 = 1 g/seedling, K3 = 1.5 g/seedling, and K4 = 2 g/seedling. Factor A consists of 3 levels, namely A1 = watering, A2 = spreading, and A3 = bag. The observation results were analyzed using analysis of variance and further DMRT test at 5% level if significantly different. The results of the study showed that the dose of NPK Phonska fertilizer 1 g/seedling (K2) gave the highest results on the Leaf Area Index, which was 2.90. The interaction treatment of NPK Phonska fertilizer dose 1 g/seedling and the pocket application method (K2A3) gave the highest results on the parameters of seedling height (12.99 cm) and tuber diameter (1.31 cm). The Leaf Area Index weakened positively on the growth of oil palm seedlings as seen from the height of the seedlings, tuber diameter, and leaf sheath length.
