Manokwari and South Manokwari Regency is one of the rice development areas in West Papua. Planting of lowland rice in Manokwari and South Manokwari always infect by blast disease. The use of resistant varieties is a major component in controlling blast disease and is the most effective, economical, and easy way for farmers. The use of blast resistant varieties is limited by space and time; in this case the use of resistant varieties must be adjusted to the composition of the P. grisea races in the area. Until now there has been no isolation and identification of P. grisea races that developed in Manokwari and South Manokwari Regency. The study aimed to identify the composition of P. grisea races in Manokwari and South Manokwari areas. The research was carried out in the laboratory and greenhouse of the Muara Bogor Experimental. Isolation and identification of race P. grisea was carried out in 2017. The results showed that the results of P. grisea isolation using monoconidia obtained 34 isolates, which were obtained from the Prafi, Masni, Oransbari and Sidey Districts. Race identification of P. grisea was obtained by 9 race groups namely race 211, 213, 241, 251, 253, 313, 333, 353 and race 373, which were dominated by race 333 as much as 41.18% and race 373 by 33.35%. The P. grisea races obtained are races that have a high virulence level.

Jajar Legowo Technology Super (Jarwo Super, JS) is an integrated rice cultivation technology on irrigated rice field based on jajar legowo 2:1 to improve rice yield by utilizing the influence of the border effect. Jajar legowo 2: 1 is difined as crops placement technique that every two rows of rice plants followed by one blank row and repeted for next rows). Part of the Jajar Legowo Super Technology component are: 1) New Superior Varieties (VUB); 2) bio-decomposer; 3) bio-fertilizers; 4) bio-pesticides and innorganic pesticides; and 5) agricultural equipment and machinery. The purpose of this study was to determine the technical feasibility, financial feasibility, and sensitivity performance of jarwo super technology (JS) rice farming at the farmer level compared to farmers who applied conventional rice cultivation or non-jarwo (NJS) technology. The research was carried out in three provencies in Sumatera such as: Aceh Province, North Sumatra and South Sumatra Province. Increased rice productivity in Aceh province is 31%, South Sumatra 37% and North Sumatra 12%. JS financial analysis of total revenue, allocation of JS cultivation cost is about 37.19% and NJS farmer 43.59%, with R/C ratio 2,69 for JS farmers, while for NJS R/C 2,29. Meanwhile, B/C ratio 1,69 for JS farmers and 1.29 for NJS farmers. The value of MBCR of introduced super jarwo technology is 5,25 which means the introduction of super jarwo technology is worth pursuing because withÂ addition production costs of Rp 1 million can increase profits worth of Rp 5.25 million. According toÂ BEP value the JS farmers will experience a loss if the decrease in yield is higher than 63% and the NJS farmers obtain lower tolerance with 56%. The results of sensitivity analysis with various scenarios showed that super jarwo farming still provides an adequate level of profit even though it tends to decrease.

Angka resmi data produktivitas padi di Indonesia diperoleh dari Survey Ubinan yang dilakukan oleh BPS. Kendala utama dalam pelaksanaan survei ini adalah terlewatnya masa panen dari sampel petani terpilih, alat pengubin yang terlalu berat, dan menyita banyak waktu dalam pelaksanaannya. Pada penelitian ini, akan dicari solusi baru untuk mengatasi kendala tersebut yaitu dengan wawancara pascapanen. Penelitian ini bertujuan untuk menjawab pertanyaan apakah pelaksanaan Survei Ubinan dapat diganti dengan wawancara pascapanen. Metode yang digunakan adalah dengan Paired Samples T-Test dan korelasi Pearson Product Moment. Variabel yang diperbandingkan ada dua yaitu produktivitas padi hasil wawancara pasca panen yang diperoleh dari SUTAS2018 dan produktivitas padi hasil survei ubinan yang diperoleh dari SUB2017 dan SUB2018. Hasil penelitian ini ada dua. Pertama, pendugaan produktivitas dengan metode wawancara pascapanen terbukti underestimate dibanding produktivitas padi hasil Survei Ubinan. Kedua, tidak cukup bukti untuk mengganti metode Survei Ubinan dengan wawancara pascapanen. Temuan ini bisa dinaikkan menjadi sebuah teori bahwa teknik wawancara suatu survei pada variabel penghasilan atau produksi maka responden akan memberi jawaban yang underestimate.

AbstrakÂ Penelitian pengaruh pembenah tanah organomineral terhadap sifat kimia tanah dan pertumbuhan tanaman jagung pada lahan kering masam telah dilakukan di Kebun Percobaan Balai Besar Mektan di Serpong Tanggerang. Penelitian bertujuan untuk menguji efektivitas formula pembenah tanah organomineral untuk perbaikan sifat kimia tanah mineral masam dan meningkatkan pertumbuhan tanaman. Penelitian menggunakan rancangan acak kelompok dengan 8 perlakuan dan 3 ulangan. Perlakuan terdiri dari kontrol tanpa pupuk dan amelioran, NPK standar, 5 tingkat dosis pembenah tanah organomineral (OM) dan dolomit. Hasil penelitian menunjukkan bahwa pembenah tanah OM dapat meningkatkan pH tanah masam dan menurunkan kelarutan unsur beracun Al. Perlakuan dolomit 1,5 t/ha menunjukkan pengaruh paling besar dalam perbaikan sifat tanah, namun pembenah tanah OM 2 t/ha menunjukkan hasil yang hampir sama. Perbaikan sifat kimia tanah diikuti dengan pertumbuhan tanaman yang lebih baik jika dibandingkan dengan perlakuan NPK rekomendasi. Perlakuan pembenah tanah OM meningkatkan pertumbuhan tanaman dan diikuti peningkatan produksi jagung pipilan. Peningkatan produksi jagung sebesar 15,7% diperoleh dengan perlakuan pembenah tanah OM sebanyak 2 t/ha. Pertumbuhan dan produksi maksimum tanaman jagung dapat diperoleh dengan aplikasi pembenah tanah organomineral dengan dosis 1.750 kg/ha.Â AbstractÂ Research of the effect of organomineral soil amendment formula to the soil chemical properties and the growth of maize on acid upland was carried out at the Experimental station of the Center for Agricultural Mechanization Research and Development in Serpong Tanggerang. The objectives of the study is to examine the effectiveness of organomineral soil amendment formula to improve the soil chemical properties of acid upland and improve plant growth. The study used a randomized block design with 8 treatments and 3 replications. The treatment consisted of controls without fertilizers and ameliorants, standard NPK, 5 dose levels of organomineral (OM) soil amendment and dolomite. The results showed that OM soil amendment can significantly increase soil pH and reduce the exchangeable aluminium, a toxic element to plant growth. Dolomite treatment of 1.5 t/ha showed the best effect in improving soil properties, but OM soil amendment 2.0 t/ha showed almost the same results. Improvements in soil chemical properties were followed by better plant growth compared to NPK treatment as a benchmark. OM soil amendment treatment gradually increased plant growth and followed by increased shelled grain corn. The increase of shelled grain corn yeild by 15.7% was obtained by applying OM soil amendment as much as 2 t/ha. Base on the yield curve, the maximum growth and yield of corn can be obtained by applying organomineral soil amendment at a dose of 1,750 kg/ha.

Soybean consumption continues to increase along with the increase in population, so most must be imported because domestic production is insufficient. According to the Agricultural Research and Development Agency (2007) to meet domestic soybean needs to suppress imports, an increase in planting area of 7.25% is needed per year. This study aims to obtain a site-specific fertilizer technology package to support the development of soybeans on dry land in Southeast Sulawesi. This research was conducted in Ahuanguria Village, Baito District, South Konawe Regency, Southeast Sulawesi Province. The activity starts from January to December 2017, using a Randomized Block Design (RBD) with each of the 5 fertilization technology packages, consisting of 225 kg NPK / Ha + 25 kg urea / ha + organic fertilizer 2 t / ha + dolomite 0.65 t / ha; NPK 200 kg / ha + urea 25 kg / ha + organic fertilizer 2 t / ha + dolomite 0.65 t / ha (recommendation); NPK 175 kg / ha + urea 25 kg / ha + organic fertilizer 2 t / ha + dolomite 0.65 t / ha; NPK 150 kg / Ha + urea 25 kg / ha + organic fertilizer 2 t / ha + dolomite 0.65 t / ha; and control (existing technology). The application of location-specific fertilization technology packages on acidic dry land soybean plants significantly increased soybean growth and yield compared to controls. The treatment of NPK 225 kg / ha + urea fertilization package 25 kg / ha + organic fertilizer 2 t / ha + dolomite 0.65 t / ha shows the yield per hectare is 1.40 tons.

Rice ragged stunt virus (RRSV) is transmitted by brown planthopper in the persistent manner. This disease in recent years has become a serious problem in Indonesia and some other countries, such as China, Vietnam, Philippines, and Thailand. Disease control is usually conducted by the vector control using insecticides, so often causes an environmental pollution. An alternative control method is using the environmentally friendly of resistant varieties. The purpose of this study was to determine the level of preference of brown planthopper (BPH) to some varieties and rice germplasms, the resistance of several varieties against rice ragged stunt virus (RRSV) disease and its effectiveness as an inoculum source of virus (RRSV). A total of 15 varieties of rice were used in preference test of BPH and resistance test to RRSV. The test for resistance varieties to RRSV was conducted by transmission of 2nd instar of BPH for 3 days of acquisition feeding period, 10 days incubation period and 24 hours inoculation period with population density of 3 BPH/plant. Disease index was calculated and used to determine the level of plant resistance. Varieties that showed resistant, moderately resistant and susceptible responses were selected and were used as a source of inoculum to be transmitted on to TN1 variety susceptible check variety to know the effectiveness of varieties as source of virus inoculum. The results showed that of the 15 varieties tested, Situ Bagendit, Utri Merah, Mentik Wangi, Mahsuri, and Inpari 1 each was less favored by BPH to settle and to multiply. Mentik Wangi, Tetep, Utri Merah, and Swarnalata each showed resistant response to RRSV. Transmission test to susceptible variety (TN1) showed that the variety of Situ Bagendit, Inpari 13, Mentik Wangi, and Tetep each has a fairly low effectiveness as a source of inoculum as indicated by the lower percentage of infection and disease index on the transmited test plants.

The opportunity to improve upland rice production on acid mineral soil is still high. However, the main problem of this soil is high soil acidity that inhibit crop growth, causing low production. The objective of this study was to evaluate the effects of agricultural waste biochar application on upland rice (Oryza sativa L.) productivity and improvement of acid mineral soil properties. The study was conducted at Agricultural Research Station of Tamanbogo, East Lampung on July-October 2013 (session 1), December 2013-April 2014 (session 2), May-August 2014 (session 3) and October 2014-February 2015 (session 4). The experimental design was split plot design, which the main plots were two types of biochar (cacao shell and rice husk), the sub plots were biochar rates (0; 5 t/ha and 15 t/ha) with five replications. The parameters measured were upland rice growth, yield and soil properties (Bulk density, soil pH and Al3+). The result showed that during the four planting seasons, the addition of cocoa shell biochar resulted better response on upland rice growth and yield compare to rice husk biochar, with crop yield of 2.54-3.97 t/ha dry grain. The dose of 5 and 15 t/ha biochar provided a stable yield and improvement of dry grain around 74.02-179.4% compare to no biochar addition for three consecutive sessions. The cocoa shell biochar applications showed better response on soil acidity (increase soil pH and reduce Al3+ ) and soil bulk density compared to rice husk. In degraded acid mineral soil, upland rice productivity and soil properties improvement can be increased by adding of 15 t/ha cacao shell biochar with a dose of 15 t / ha for getting dry grain more optimal.

Artificial mutation could be used in the formation of base population for selection. Local varieties which have a wide distance of relationship are expected to have a greater opportunity for obtaining more diverse offspring. The purpose of this study was to select five distinct local tidal swamp rice varieties of South Kalimantan that could be used for parental mutation. The study was conducted from March to December 2009. The distance of varietal relationship was estimated by cluster analysis using the SPSS Programme Version 11.5. Selection of the five best varieties was carried out by the Exponential Rank Method (ERM) applying 7 criteria, namely plant height, number of panicles, panicle length, grain weight/panicle, number of grains/panicle, weight of 1000 grains, and grain yield. Results of the cluster analysis based on a 82.5% similarity level showed that diversities of the 40 accessions of local tidal swamp rice in South Kalimantan were spread in four clusters, namely Cluster I (13 varieties), Cluster II (1 varieties), Cluster III (6 varieties) , and Cluster IV (20 varieties). Five varieties that were selected based on the cluster analysis and the ERM were Siam Harli, Siam Unus (Bumi Makmur), Siam Kuatek, Datu, dan Siam Unus (Barambai).
