Research on milled rice color and texture using digital image processing technique is becoming important, due to its potential use as a basic method for rice derived variety identification. The research was aimed to identify milled rice of varieties Basmati, Inpari 1, and Sintanur using color and texture analysis based on digital image processing. A combination of color and texture analysis was used as input parameter and then analyzed in the next step using the artificial neural network (ANN) to determine input parameter that has the highest accuracy level. The experiment was conducted at Merauke Experiment Station, Papua Institute for Agriculture Assessment Technology from May to July 2011. The materials used were milled rice of varieties Basmati 370, Inpari 1, and Sintanur that were previously grown at Sukamandi Experiment Station of the Indonesian Center for Rice Research (ICRR). All samples were qualified as grade 1 based on SNI 6128:2008. Fifty image samples were taken from each variety to get a total of 150 images to be analyzed for their colors and textures using the digital image processing. The color and texture data were analyzed using the analysis of variance (ANOVA) and further tested using the Duncanâ€™s Multiple Range Test (DMRT) to obtain the median, while the data spread was analyzed using the boxplot method. The combination of color and texture as input parameters were analyzed using the ANN. One hundred and five rice data were used for training and 45 data were for testing. The results showed that the digital image processing and ANN recognized three output parameters in rice varieties of Basmati, Inpari 1, and Sintanur. Texture analysis with five input parameters were considered the best factor to be used in the ANN model with 100% accuracy.

A study was carried out to identify the composition and distribution of Xanthomonas oryzae pv. oryzae (Xoo) pathotypes in rice crops in South Sumatera, during the 2012 planting season. Three activities were conducted, namely collection of rice leaf samples from the field, isolation of Xoo from the leaf samples in the laboratory, and testing pathotypes of the Xoo in the screen house. Rice leaves showing typical bacterial leaf blight (BLB) symptom were collected from various farmersâ fields. The samples were detached and put into paper envelopes, and taken to the laboratory for isolation of Xoo, at the Laboratory of Pythopathology of Indonesian Center for Rice Research, Sukamandi. Pathotype testing was done in the ICRR screen house by inoculating the leaves of five differential rice varieties with inocula of the Xoo isolates collected. Resistances of the rice differential varieties were determined based on the BLB disease severity. Inoculated plant with disease severity <11% was considered resistant (R) and disease severity >11% was susceptible (S). From 122 samples of rice leaf infected with BLB collected from the rice production centers in South Sumatera, one hundred and twelve Xoo isolates were obtained from the isolation. The Xoo pathotype identification showed that pathotype III was the most dominant in South Sumatera during the 2012 planting season (67 isolates or 60.0%) followed by pathotype IV (28 isolates or 25%), and pathotype VIII (17 isolates or 15.0%).

Nineteen field experiments were conducted in the provinces of West Java, Central Java, East Java, and Bali, during the 2008 dry season and the 2008/2009 wet season, to determine yield potential, yield stability, resistance to pests and diseases, and to evaluate the grain qualities of five introduced hybrid rice varieties and four hybrids from the Indonesian Center for Rice Research (ICRR). In each location, the experiment was arranged in a randomized block design with four replications, using 4 m x 5 m plot size. Observations were made on grain yields, yield components, plant resistant to major pests and diseases, and grain quality. The plant resistance to brown plant hopper (BPH), bacterial leaf blight (BLB), and tungro was evaluated at the glasshouse. Results showed that in some locations the hybrid rice yielded significantly higher than did inbred variety Ciherang, but it was inconsistence over locations. In the dry season, the average yields of hybrid rice were higher than those in the wet season. The average yield of two hybrids, namely MR1 and H30 over 19 locations was each significantly higher than that of Ciherang, however, the difference was not more than 9.6%. These two hybrids were found adaptive to all locations. Hybrid MR1 was resistant to BLB [Xanthomonas oryzae pv, oryzae (Xoo) patotipe III], whereas H30 was moderately resistant to Xoo pathotype III and BPH biotype 3. The amylose contents of MR1 and H30 was medium and the head rice percentages was >80%.

Soybean pod feeder, Helicoverpa armigera is a major insect pest of soybean in Indonesia, where severe attacks can reduce yield significantly. This insect has a wide range of host plants. One of the Integrated Pest Management (IPM) components is using a trap crop. A study was conducted in the green house at the Indonesian Legumes and Tuber Crops Research Institute (ILETRI), Malang, from Januari to Februari 2011 to evaluate the potential use of musk basil plant as a trap for egg laying of the adult soybean pod feeder. The experiment was arranged in a complete randomized design with four replications. Maize plants of 54 and 57 days old, soybean plants of 35 days old, and musk basil plants were each inoculated with two pairs of adult insects for two days at 02.00 pm. The numbers of eggs laid by the insect on the plants were recorded at two days after infestation (DAI). The results showed that maize plants of 54 or 57 days old were the most preferred host for laying eggs, followed by the musk basil plant. The pest laid 63% of the eggs on 54 days old maize plants, 34% on the 57 days old maize plants, and only 1.8% on the musk basil plant. None was found laying egg on soybean plant. The insect preferred most maize stem (39.7%) to lay eggs, on maize leaves (35.2%), cob hair (23.1%), and on cob (1.3%). On musk basil plant, 70% of the eggs were laid on the fruits and 30% on the leaves. Maize plant was the best egg trap, while musk basil plant did not have a potential as trap plant for soybean pod feeder insect.

Stagnant flooding (SF) is a major problem in floodprone rice ecosystem where the depth of flood water ranging from 20-50 cm in the entire seasons. In Indonesia this kind of water stress can be found in swampy basin area or Rawa Lebak. A study was conducted to determine the genetic parameters related to rice plant adaptability to SF. Eighteen rice genotypes including the recently developed 6 pairs of SUB1 near isogenic lines (NILs) of widely planted varieties and checks were tested under 50 cm depth of SF in the 2009 wet season at Los Banos, Philippines. The results showed that most of genotypes showed different responses on morphological and agronomical characters under SF and normal conditions. Most of the SUB1 NILs had lower grain yields than their respective parents. This was because SUB1 suppressed shoot elongation and less restoring contact with the air. Some SUB1 lines such as PSBRc68 and IR70181-32, however, produced high grain yields under this condition. Under SF condition, rice genotypes required shoot elongation to allow restoring contact with the air, therefore the traits that related to growth attributes such as shoot weight, leaf weight, LAI, stem diameter, plant high, and tiller number were strongly correlated with the grain yields. These traits also had broad genetic variability, high heritability, and strong correlation with grain yields. Selection under real stress SF conditions was effective to obtain high yielding genotypes and also tolerant.

The possibility of sustainable use of sweet sorghum as raw material for animal feed and bioethanol need to be supported by evaluation and selection of sweet sorghum genotypes for high biomass production, sugar content of the stalk, and its ratooning ability. An experiment was conducted at the experimental field of the Cereal Crops Research Institute, Maros, during the anomalic season (La Nina) from November 2009 to September 2010. Fourteen genotypes of sweet sorghum were planted in plots arranged in a randomized block design with three replications. The sorghum seeds were planted as primary crop plants in November 2009 and harvested in February 2010. Ratoons of the primary crop (Ratoon I) started to grow in February 2010 and was harvested in May 2010, while Ratoon II started to grow in May 2010 and was harvested in August 2010. The results showed that none of the sorghum genotypes had the potential of high fresh biomass production, high ratooning ability, and high sugar content of stalk juice. Genotype 15021A produced the highest fresh biomass (63.4 t/ha), but had low ratooning ability l (33-44%) and low sugar stalk juice content (9 brix). Meanwhile, genotype 15105B had high ratooning ability (64-88%) and high sugar content of stalk juice (13 brix), but it had a low fresh biomass production (41.8 t/ha). The amount of fresh biomass production from the primary crop plants until Ratoon II was determined by the potential production of fresh biomass/ha and ratooning capability of the sorghum genotype. The fresh biomass production of the sorghum genotype was correlated with the plant height and the date of flowering.

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major disease of rice in Indonesia which remains difficult to be controled. A number of bacterial isolates had been collected and screened for their ability to antagonize Xoo disease. Six isolates with the highest antagonistic potential and wide spectrum were chosen for studies based on their ability to control the disease. Bio-formulations consisted of single or mixtures (consortium) of the bacterial antagonists were formulated and tested for their effectiveness to control BLB under field trials in Cianjur, West Java. Efficacy of the bio-formulations against the disease on different rice cultivars varied significantly with HDB reductions ranging from 10.5% to 29.4% among the cultivars tested in the WS 2010/2011. The mixture of A6 + A8-bentonite showed a good ability to reduce BB infestation by up to 25%. Performance of the A6+A8-bentonite formulation also exceeded those of the individual isolate formulations, such as Burkholderia spp. E76-bentonite and S. marcescens SKM-kaolin. Application of the bacterial mixture formulation did not affect significantly on rice plant height, number of tillers, and weight of 1000 grains, but increased grain yield up to 8%. This study showed that the advantages of single or mixed cultures were apparent and further evaluation for application of bio-formulation need to be done under more intensive field conditions.

Problem faced on continous soybean seed supplies based on location and seasons (the Jabalsim) system is that soybean crops are harvested during the rainy season. This has caused the seed quality does not meet the standard requirement set forth by the government. The purpose of this study was to evaluate the effectiveness of the flat bed dryer with an LPG energy source, for soybean seed drying. Research was conducted at the Laboratory of Agricultural Mechanization of the Indonesian Legumes and Tuber Crops Research Institute (ILETRI), in Malang and at Muneng Experiment Station, Probolinggo, East Java, from January to December 2010. The study included designing and performance evaluation of the dryer for its drying capacity and seed viability, and the analysis of financial benefit to the seed grower using the B/C ratio. The performance evaluation was done using soybean varieties Kaba and Grobogan. The results showed that drying process of both soybean varieties followed an exponential model with the coefficient of determinations (R2) was 0.94 to 0.99. Drying soybean seeds using the flat bed dryer using LPG as the energy source was faster than that using the drying floor. The drying rate of soybean seeds of Kaba variety using the flat bed dryer and using the drying floor was faster than those on variety Grobogan. It took 6 hours for drying 260 kg soybean seed with 20% moisture content wet basis (obtained from 1 ton of unthreshed soybean) into 11% wet basis, thus the drying capacity of the dryer was only 43 kg/hour. At an average rate of drying air temperature 45.5oC, the viability of the soybean seeds was 73 to 84%, still meet the standard seed quality of the government (minimum 70%). The cost benefit ratio (B/C ratio) was 1.12 when the price of the dryer is Rp 22 million/unit and the service charge for the soybean seed drying is Rp 2,600/kg seeds. Technically and financially, innovation of the flat bed dryer with an LPG energy source was still feasible to be applied by seed producers during the wet season, following the Jabalsim seed system.
