KERAGAAN VARIETAS DAN GALUR HARAPAN PADI GOGO PADA DAERAH ALIRAN SUNGAI BATANG ASAI SAROLANGUN JAMBI (The Performance of Upland Paddy Varietas and Lines in Batang Asai Watershed Sarolangun Jambi)
Potential of upland paddy in dryland watersheds has not been utilized optimally to support increasing food security. Main constraints of upland paddy cultivication in watershed are drought and blast disease disorders. In order to obtain high yielding upland rice varieties which is tolerant to drought  and blast pathogen, five varieties have been cultivated in Batang Asai Sarolangun Jambi watersheds at May-October 2011. These varieties are Inpago 4, Inpago 5, Inpago 6, Limboto, and Towuti, 1 (one) strain expectation (B11579E-MR-7-1-1), and 1 (one) Senimas local varieties. Experiment was arranged in Randomized Block Design (RBD) with 4 replication. Results revealed that the climatic conditions are not conducive for growth and crop production, due to low in rainfall and increased rainy days.These caused unoptimal plant growth, triggered high pests population, and increased in high percentage of empty grains. The high potential was indicated by Limboto, while Towuti showed the lowest yield. High yield of Limboto was supported by high yield component. Compared to other varieties, Limboto also shows high  drought tolerance .  Key words : Upland Rice, watershed, drought, lin

KAJIAN PAKET PENGOLAAN TANAMAN TERPADU DAN PAKET PETANI PADI GOGO PADA DAERAH ALIRAN SUNGAI BATANG ASAI JAMBI
Upland rice production is still low compared with the result of research and genetic potential. The low yield is caused by the use of cultivation technology that is not optimal and the limited of high yielding varieties cultivated that made many farmers still grow local rice for generations. High yielding varieties and Integrated Crop Management (ICM) technology is one of the reliable innovative technologies to increase the upland rice productivity. The study aims to determine the growth and production of upland rice with ICM technology package compared to farmer technology package. The experiment was conducted in the Batang Asai watershed, Panti Village, Sarolangun Jambi District. The study of ICM package and farmers package done by planting the two packages side by side on planting area of 1 ha each, consisting of four farmer cooperator, as well as for replicates. The research was done by using factorial design that compares the ICM package with farmers’ package through the t test. The results indicate that the ICM package provide a better growth and yield than the farmers package, such as the low intensity of leaf and neck blast disease and rice pest pests walang, positively impacted the percentage of grain pithy, weight of 1000 seeds and results. ICM package gives the highest yield 5216 kg/ha, while the farmer package 2,170 kg/ha, so there is an increase in the results of 3,046 kg/ha or 140.37%.

PENGEMBANGAN METODE PREPARASI CELLULOSE NANO FIBERS (CNF) RAMI (Boehmeria nivea) UNTUK FILLER MATERIAL KOMPOSIT BIOPLASTIK DENGAN MATRIKS PATI TAPIOKA
The development of bioplastics composites from various natural polymers reinforced with cellulose nanofibers (CNF) from ramie (Boehmerianivea (L.) Gaud) and Precipitated Calcium Carbonate (PCC) has become a field of increasing interest. In this study, the effect of CNF ramie-PCC on the physical, mechanical, thermal and biodegradabilty properties of a cassava starch matrix composite was examined. The samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), particle size analysis (PSA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), moisture absorbtion test, and biodegradability test.
The novelty of this work lies in isolating CNF from ramie using chemical-ultrasonication treatment. The cellulose nanofibers were successfully isolated from ramie with a diameter 34,2 ±7,07 nm. Indeed, there is a decrease in the hemicellulose and lignin content while the cellulose content increases due to the pulping and bleaching processes. After that, the synthesis and characterization of CNF from ramie fibers reinforced by PCC hibrids nanocomposite with tapioca starch matrix. Nanocomposites are made by using casting solution and glycerol as plasticizers.
The optimum tensile strength was obtained upon the addition of 4 % PCC. The addition of PCC improved the thermal stability of bioplastic/PCC composites. The results of X-ray Diffraction testing showed an increase in the crystallinity of the bioplastic/PCC composites with increase in PCC content but there is a decrease in the moisture absorption.
The results show that the CS4CNF6PCC sample has the highest crystallinity index and tensile strength of 30,76% and 12,84 Mpa respectively. The addition of CNF ramie and PCC in nanocomposites leads to moisture absorption, crystallinity and thermal stability have increased. The SEM image shows that the CNF ramie is bound in a matrix and the PCC is weakly bound in the tapioca starch matrix because of the calcium clumps in the matrix. In general, FTIR indicated that the nanocomposites hibrid were hydrophilic, and the addition of PCC reduced the hydrophilic properties by damaging the hydrogen bonding between starch molecules and water. In the soil burial test, the lowest mass loss was in CS10CNF (70,2%) after 6 days. Meanwhile, the smallest fungus growth rate was CS2CNF8PCC and CS4CNF6PCC.
