Rice is the staple food of Indonesia's population. Various problems occur in an effort to increase production and productivity. One problem is the attack of yellow rice stem borer (PBPK) which may result in yield losses up to 90%. Utilization of parasitoid is an alternative to suppress the attack of Yellow Rice Stem Borer. The study was conducted in Tabanan, covering three locations with the altitudes of 50, 300, and 550 meters above sea leve, and at the Plant Pests and Diseases laboratory of the Faculty of Agriculture, University of Udayana. The study aimed to determine the effectiveness of parasitization of the best Yellow Rice Stem Borer as a natural control agent at different altitudes. The method used was survey by taking a sample group of Yellow Rice Stem Borer eggs with a purposive random sampling in the area of 2.5 hectares (one block in each location was an area of 0.5 hectares) at each location. Observations on parasitoid found in Yellow Rice Stem Borer eggs were done on parasitoid species diversity, equality, abundance, parasitation level, sex ratio, and the pattern of parasitoid invasion. The results showed three species of parasitoid eggs PBPK as biological control agents. Parasitation level of T. rowani and T. japonicum was the highest at the altitude of 50 meters above sea level, while T. schoenobii at the altitude of 300 and 500 meters above sea level.

INDONESIA Pengelolaan DAS merupakan masalah serius karena luas lahan kritis meningkat yang diakibatkan oleh pengelolaan lahan yang tidak sesuai dengan kesesuaian dan kemampuannya dan tidak disertai dengan usaha konservasi tanah dan air, serta perubahan pola penggunaan lahan bervegetasi. Pengukuran lapang parameter yang berpengaruh terhadap hidrologi suatu DAS tidak mudah dilakukan karena karakteristik yang bersifat kompleks dan komprehensif. SWAT (Soil and Water Assessment Tool) merupakan suatu model yang dapat membantu dalam memperkirakan kondisi hidrologi berbasis proses fisik (physical based model). Penelitian ini bertujuan untuk untuk mengetahui nilai validasi aplikasi model SWAT di sub DAS Ciliwung Hulu dan menentukan Pengelolaan Lahan Terbaik (PLT) pada lahan pertanian di sub DAS Ciliwung Hulu. Metode yang digunakan meliputi pengumpulan data, pengolahan data input, penggunaan model SWAT, kalibrasi, validasi dan simulasi Pengelolaan Lahan Terbaik (PLT). Penelitian dilaksanakan dari bulan Juni 2011 sampai dengan Juni 2012. Validasi debit harian bulan Februari dan Maret tahun 2009 dan 2011 menunjukkan R 0,88 dan NSE 0,74. Nilai kalibrasi ini menunjukkan bahwa model SWAT dapat digunakan untuk memprediksi kondisi hidrologi pada sub DAS Ciliwung Hulu. Aplikasi teras bangku, penanaman menurut kontur, penanaman menurut strip dan agroforestri dapat menurunkan aliran permukaan. Teras bangku terbukti paling efektif menurunkan aliran permukaan hingga 79,21%.INGGRIS

Various study of multi-location test of rice genotypes was strongly influenced by field and environmental factors. This study aimed to implement and to identify wetland rice genotypes. Multi-location test was conducted on some rice genotypes in Southeast Sulawesi in 2010 at various locations. Randomized block design was used with three replications in different locations. Data were analyzed using AMMI model. Results showed that rice production had the main effect with the genotype of KUI 1 and KUI 2. Moreover, BIPLOT test found that the genotype 2 of S3393-2F-17-1-1 was the only one of unstable genotype, and the rest were stable genotype. Not surprisingly, genotype (G) 4 (S3382-2D-PN-4-1), G 5 (S3382-2D-PN-6-3-3), G 7 (S3382-2D-PN-2D-1-1), G 11 (S3382-2D-1-1), G13 (Ciherang) and G 14 (Cisantana) were relatively stable. Those genotypes could be recommended as the high potential yield due to higher average production compared with general average. This study also indicated that G 3 (S3381-2D-PN-27-2), G 9 (S4359-E-11-2), and G 12 (IR64) are very suitable for growing in location A at Ladongi. Moreover, in location B study suggested that G 11 (OBS-9595) should be recommended at Wundulako. Finally, in Lambuya, particularly in location C, study indicated that some genotypes can grow well, viz. G 6 (S3382-2D-PN-17-3), G 8 (S4690 G-KN-4-3) and G 14 (Cisantana).

One of the problems encountered in the development of sugarcane (Sacharrum officinarum L.) includes the availability of sugarcane seed both in quality and quantity. Evaluation of bud sett planting method in seed production was required in order to achieve the expected results. The study was conducted at the experiment station Muktiharjo, Central Java in 2012 using PSJT 941 varieties. Treatments applied were the different number of buds on bud sett which were at 3 levels, 1 bud, 2 buds or 3 buds. Research was arranged in a randomized complete block design (RCBD) with 5 replications. Observations were conducted on germination, tillering, plant height, number of stems, number of suckers and number of buds. The data obtained were analyzed with ANOVA and further tested using the Duncan test. Production assessment modeling approach was performed by a regression analysis. Calculation of stem number on 2 buds showed the highest with 9.6 stems/m, 9.2 buds/stem and with the sucker numbers lowest at 0.38 suckers/m. The highest production buds was obtained at planting 2 buds with 847,848.06 buds/ha which can be used as 8.83 ha for the milled sugarcane plantation. Assessment of bud production per hectare could use equation Y = 159655,48.e0,171.X with the independent variable of stem numbers per meter with a correlation coefficient of 0,9007 and a standard error of 1,0699.

Most people in Maluku Islands have long used non-rice food consumption, especially tuber crops and maize. The development of diversification of non-rice food consumption certainly needs to be supported by the availability of adaptive crop cultivation technology to climate change. Cropping pattern is one of the appropriate steps for smallholder farmer to increase land productivity. An experiment of maize/peanut intercropping pattern had been conducted to determine optimum Nitrogen (N) rate for maize at different planting spacings in intercropping pattern with peanut in dryland of Makariki Village, Central Maluku. The experiments were arranged in a Split Plot Design with 3 (three) replicates. The main plot was maize spacing, namely: (i) J1 = 80 x 25 cm, 6 rows of maize, 2 rows of peanut, (ii) J2 = 160 x 25 cm, 3 rows of maize, 4 rows of peanut, and (iii) J3 = 240 x 25 cm, 2 rows of maize, 6 rows of peanut. The sub-plot was N rate (kg/ha), namely: (i) N0 = 0-0-0, (ii) N1 = 45-50-60, (iii) N2 = 90-50-60, (iv) N3 = 135-50-60, and (v) N4 = 180-50-60. The results showed that plant height, cob circle and yield of maize grown at different planting spacings in intercropping patterns in Makariki, Central Maluku affected by N fertilizer application. The application of N fertilizer increased growth and yield of maize by following a quadratic pattern. The use of maize spacing of J1 (80 x 25 cm) in intercropping with peanut requires the addition of the optimum N rate of 302 kg urea/ha, which gave the highest maize yield (t/ha) compared with other planting spacings.
