Some theories suggest that the important role of food reserves to maintain seed quality. On soybean seed, food reserves in the form of protein, carbohydrates, and fats. Generally researchers claim that high fat will reduce the quality and vitality of seeds in storage. Setting up food composition will maintain the quality and vitality of seeds in storage. Composition of food reserves is an equilibrium, increase one portion of food reserves would lower portion of the otherFood reserves play an important role in determining the quality of soybean seed. Deposit composition can be modified by eating nutrients nitrogen and phosphorus, and association with Rhizobium bacteria. Setting up the composition of foods believed to increase the quality and viability of soybean seed.The results showed that soybean growth variables measured with ILD, LAB, LTR, and BKA influenced by nitrogen and phosphorus, both single and two-factor interactions. Variables BKA instrumental in increasing seed production. The composition of the food reserves are also affected by the interaction between nitrogen and phosphorus except carbohydrates. Increase in protein content followed by a decrease in fat content in the seed, whereas carbohydrate content did not experience the difference. It is generally known that the root dry weight, production, 1000 grain weight and seed protein obtained at optimal combination of nitrogen 45 kg ha-1 and phosphorus at 90 kg ha-1. Information from this trial will be better if done testing the model composition and food reserves to do with the ability of seeds to survive naturally in storage.Keywords: food storage, enzymes, seed production

This study aims to determine the purpose of research to look at the physical characteristics of the plant and the quality of latex rubber (Hevea brasilliensisMull. Arg) lowlands and highlands. This study was conducted have been carried out in low-lying areas (Tables cottage village, District Mestong, Muaro Jambi) with altitude <200 m above sea level (asl), while the highlands (In the village of Khajuraho), District of Batang Merangi, District Kerinci with altitude> 700 m above sea level (asl). This research was carried out for 3 monthsPlant samples used in this study is the people's rubber plant clone 24. BPM object taken is lowland rubber plant with a height of <200 m asl and highlands> 700 m asl, rubber plants have aged> 7 years (already in production). Experiments conducted using survey method in community gardens and quality testing laboratory tested latex UPTD BPSMB Jambi.The parameters observed were: Physical Plant consists of the calculation of the number of branches, leaf dry weight measurement (gcmˉ²), and measurement Trunk circumference (cm). While measuring the quality latex rubber tnaman consists of: Testing the dry rubber content, the determination of levels of Dirt Lteks, the determination of levels of Abu. The researcher also the determination of point coordinates and Altitude, observations Age Start Produce, and pengukuan production and productivity. Data field observations conductedBased on field observations in the average number of branches of the rubber plant lowland and highland 19.45 8.4. The average dry weight of plant leaf heavier rubber plateau is 0.006412 g cm2 compared to the dry weight of the rubber plant leaves lowland is 0.004187 g cm2. . The girth between lowland rubber plant is 65.05 cm larger than the girth of rubber plants plateau 43.97 cm, quality latex rubber plant lowland better than latex rubber plants plateau. Lowland rubber plant at an altitude of 62 m above sea level at point coordinates 103º and 01º N latitude, and rubber plants plateau at an altitude of 806 m above sea level at point coordinates 101º and 02º N latitude. Age plains below its rubber trees start producing clones BPM 24 is 4 years, while the age of the same clone rubber plants in high dtaran start producing 8 years. Rubber latex production plant for low-lying lower than the production of latex rubber plant plateau.Keywords: characteristics, quality, physical and chemical, latex, rubber plants.

In the framework of the management of the river basin (DAS) to develop a model of watershed management in small extents (DAS Micro) will be able to accommodate the needs of sustainable watershed management objective that includes the object biophysical, social, economic, and institutional. Watershed management should be integrated from upstream to downstream areas involving all parties associated with the principle of one river, one plan and one integrated organization. Micro DAS Stem Tegan is part of the Sub Watershed Batang Bungo who was instrumental for the Dusun community Rantau Pandan and LUBUK Wood Aro in Sub Region Senamat Ulu Pandan and Orchard and Orchard Muaro Make The heart of the District III Ulu Muaro Bungo District, Jambi Province. Sustainability of the river is very important this river is a placeholder from catcment area dominated by land titling 25-40% (rather steep) with extents 1868.88 Ha. The main potential biophysical land areal MDM is a District Snapshot water (DTA) or Catchment Area. Micro DAS Stem Tegan is pensuplai water to Sub DAS further Batang Bungo will join the DAS Batanghari. Biophysical problems onto the areal MDM is low soil fertility, soil erosion splash and sheet type, slope of land, availability of critical land and the land has the potential to become critical. The main potential of the social economy of institutional structures are formed community orchard, potential productive workforce, there is a means of education, worship, health, as well as some economic institutions such as markets and society. Social and economic problems that are being recorded from areal MDM is a high rate of population growth, poverty, and dependence of agricultural land.Keywords: Soil and water conservation and cultivation zones
