Pest and disease are important biotic obstacles to increase rice yield and production in Indonesia since adoption of green revolution to increase rice yield. This is partly due to the irrational use of pesticides. This paper is a review on information technology (IT) based decision support system (DSSs) in line to the integrated pest management (IPM) implementation strategy for extensionists and farmers in the fields. IPM integrates compatible control techniques to manage pest populations below the economic injury level. IT based DSSs ultimately needed so that extension workers and farmers can quickly access sources of information about pests and diseases as well as prediction of development and control techniques to implement IPM. Web based DSSs to grow healthy rice plant, pest observation and monitoring, cyber extension to make famers an expert on IPM were available, except on how to identify and utilize natural enemies are still lacking. Indonesia need to develop more IT based DSSs which accessible on web as well as on smartphone and create enabling environment for improving IPM implementation on rice not only by officer but also gradually by farmers it self to control pests and diseases of rice which are still an obstacle in increasing production.Keywords: Rice, pest, diseases, integrated pest management, information technology AbstrakSISTEM PENDUKUNG PENGAMBILAN KEPUTUSAN HAMA TERPADU PADA TANAMAN PADI BE RPBEANSGIESNDALIAN TEKNOLOGI INFORMASISejak inovasi revolusi hijau diintroduksikan di Indonesia, hama dan penyakit tanaman semakin berkembang sehingga menghambat upaya peningkatan produktivitas dan produksi padi. Hal ini antara lain disebabkan oleh penggunaan pestisida yang tidak rasional. Tulisan ini mengulas kesiapan sistem pendukung pengambilan keputusan (SPPK) berbasis teknologi informasi (TI) dalam pengendalian hama terpadu (PHT) oleh penyuluh maupun petani di lapangan. PHT mengintegrasikan berbagai teknik pengendalian hama dan penyakit agar tetap berada di bawah ambang ekonomi. TI diperlukan agar penyuluh dan petani dapat dengan cepat mengakses sumber informasi tentang jenis hama dan penyakit tanaman serta perkiraan perkembangan dan teknik pengendalian untuk penerapan PHT. SPPK berbasis TI yang bertujuan menjadikan tanaman tumbuh sehat, pengamatan dan monitoring perkembangan hama dan penyakit, serta penyuluhan berbasis web sudah tersedia, kecuali identifikasi dan cara pemanfaatan musuh alami. Oleh karena itu perlu dikembangkan SPPK berbasis TI yang dapat diakses melalui web maupun telepon pintar dan menciptakan lingkungan yang memungkinkan untuk meningkatkan implementasi PHT tidak hanya oleh petugas tetapi juga petani secara bertahap dalam upaya mengendalikan hama dan penyakit padi yang masih menjadi kendala dalam peningkatan produksi.Kata kunci: Padi, hama, penyakit, pengendalian hama terpadu, teknologi informasi

The study aimed to determine the effect of nitrogen rates and planting systems on the incidence and severity of rice blast under naturally infected rice plants and their relationship to rice yield performance. Recommended nitrogen rate for both direct seeding was 93.2kg/ha. Treatments consisted of 75% recommended-N rate, 100% recommended-N rate, 150% recommended-N, and existing farmer’s practice. Treatments were applied in a three-way splitted-N application at 14, 30, and 45 days after planting, respectively. The results indicate that rates of N fertilization affected disease incidence of the rice blast where the low-N application was generally lower than recommended-N rate, high-N rate, and farmer’s practice, both on jajar legowo 2:1 and broadcasted direct seeding. This study revealed that recommended-N application, although has a higher disease incidence than low-N application, could tolerate yield loss due to rice blast by producing more productive tillers, number of grains per panicle, and reducing the number of unfilled grains. This study generally showed that jajar legowo 2:1 direct seeding gave lower disease incidence and severity to the rice blast than broadcasted direct seeding. The study suggested an appropriate recommended-N rate and jajar legowo 2:1 direct seeding (double row) was incorporated into the rice blast management strategies.

English A way to increase rice productivity and production is to increase efficiency by technological innovation. Integrated Crop Management (ICM) is an approach to improve the efficiency of rice farming by integration of technological components that are applied according to local specific condition. This study aims to analyze technical efficiency and inefficiency of integrated crop management implementation in rice farming. The study was conducted in Jaten Subdistrict, Karanganyar Regency, Central Java Province, in 2017. Primary data was collected from samples of 51 farmers that implemented the ICM and 42 farmers that did not use ICM. Data were analyzed using stochastic frontier production function that was estimated with the Maximum Likelihood Estimation method. The results show that rice farms have been technically efficient in general. The technical efficiency of ICM adopters in the range of 71,41-98,14% with average 94,04%, higher than those of non ICM adopters in the range of 68,50-96,96% with average 91,72%. There is a room for increasing efficiency. Formal education and ICM adoption increase technical efficiency. Farmer's ability to implement PTT can be improved through extension and training programs. Indonesian Salah satu cara untuk meningkatkan produktivitas dan produksi padi adalah dengan meningkatkan efisiensi melalui inovasi teknologi. Pengelolaan Tanaman Terpadu (PTT) merupakan sebuah pendekatan untuk meningkatkan efisiensi usaha tani padi dengan integrasi komponen-komponen teknologi yang diterapkan sesuai spesifik lokasi. Penelitian ini bertujuan untuk menganalisis efisiensi dan sumber inefisiensi teknis pada penerapan PTT usaha tani padi sawah. Penelitian dilakukan di Kecamatan Jaten, Kabupaten Karanganyar, Jawa Tengah, pada 2017. Data primer dikumpulkan dari 51 petani yang menerapkan PTT dan 42 petani yang tidak menerapkan PTT. Analisis data menggunakan fungsi produksi stokastik frontier yang diduga dengan metode Maximum Likelihood Estimation (MLE). Hasil analisis menunjukkan bahwa usaha tani padi sawah umumnya sudah efisien secara teknis. Nilai efisiensi teknis usaha tani dengan penerapan PTT berkisar 71,41-98,14% dengan rata-rata 94,04%, lebih tinggi daripada usaha tani tanpa penerapan PTT yang formal berkisar 68,50-96,96% dengan rata-rata 91,72%. Masih ada peluang untuk meningkatkan efisiensi teknis. Pendidikan dan penerapan PTT berpengaruh positif terhadap efisiensi teknis. Kemampuan petani dalam menerapkan PTT dapat ditingkatkan melalui program penyuluhan dan pelatihan.
