“…Jika serangan trips terjadi selama fase vegetatif dan fase berbunga (generatif) maka kehilangan hasil yang diakibatkan akan semakin tinggi (Indiati 2003;Hossain et al 2011). Selain di daerah Ngawi, serangan trips yang parah juga terjadi di daerah Malang, Bedali (Lawang), Muneng (Probolinggo), dan Ponorogo (Indiati & Marwoto 2017). Di Muneng (Probolinggo), serangan trips terjadi mulai bulan April sampai dengan September dengan puncak serangan terjadi pada bulan Juni.…”

“…Di Muneng (Probolinggo), serangan trips terjadi mulai bulan April sampai dengan September dengan puncak serangan terjadi pada bulan Juni. Selain menyerang kacang hijau, trips di daerah Muneng juga menyerang tanaman kacang yang lain, seperti kacang tunggak, kacang tanah, dan kedelai (Indiati & Marwoto 2017). Tujuan penelitian ini adalah untuk mempelajari pengaruh waktu tanam dan periode pengendalian terhadap populasi dan intensitas serangan Megalurothrips usitatus (Bagnall) pada tanaman kacang hijau.…”

Megalurothrips usitatus (Bagnall), is the main pest on mung bean causing crop failures, thus the objective of this study was to determine the proper mung bean planting time and timing of thrips control, with minimal risk of yield loss. This experiment was conducted at Muneng Research Station, Probolinggo, East Java during dry season of 2015. This research was conducted using a split-plot in completely randomized design with planting time as the whole plot and pest control time treatment as a sub-plot with 2 repetitions. There were six planting time as the whole plot: first planting 20 May 2015, second planting 30 May 2015; third planting 9 June 2015; fourth planting 19 June 2015; fifth planting 29 June 2015, and sixth planting 9 July 2015. While, the pest control time treatment was done with an active agent fipronil insecticide as a sub-plot which consists of 4 treatments: (1) without insecticide treatment during vegetative and generative phase, (2) insecticide application during generative phase only, (3) insecticide application during vegetative phase only, and (4) full insecticide treatment during vegetative and generative phase. The results showed that the symptom of thrips attack began to appear 21 days after planting (DAP) by observing initial curling of trifoliate leaves. The thrips population per plant increases with increasing plant age. The highest populations of thrips were found on the second planting time (end of May) combined with no control during vegetative and generative phase, which is 17.8 individuals/plant at 18 DAP. The highest yield lost, was found on first planting time (90.2%) and second planting time (85.6%), if there is no control during vegetative and generative phase. It is indicated that in May become the appropriate time as a critical period of mung bean against thrips attack. From this study it can be concluded that to reduce the risk of high yield losses due to thrips attacks is to avoid from planting green beans in May. In thrips endemic areas, pest control at the beginning of plant growth and during the vegetative phase is a determining factor for the yield of mung bean. The season of “bediding” can be a warning sign for farmers before thrips infestation and to immediately take pest control measures.

“…According to [3], one of the efforts to control the planthopper pests is the spraying of pesticides with the appropriate dose. The inappropriate dose will cause the various undesirable effects, such as environmental pollution, pests become resistant to various types of pesticides, and pests become quickly adaptable to environmental changes [4].…”

In this paper, we develop a mathematical model to analyze interactions between planthopper pests as prey and menochilus sexmaculatus and mirid ladybug as two predators where prey is controlled by pesticides. The interaction between predator and prey is modeled using the Holling type II response function. The predator and prey growth are modeled using a logistic function. From this model, we obtain eight equilibrium points. The three of these equilibrium points are analyzed using linearization and locally asymptotically stable. We simulate this model using data to predict the dynamics of planthopper population and its predators. Simulation result shows that all of these populations will survive because they are influenced by pesticide control and predation rates.Keywords: control of pest; predator-prey model; the Holling type II; the logistic function. AbstrakPada penelitian ini, kami membangun model matematika untuk menganalisis interaksi antara hama wereng sebagai mangsa (prey) dan menochilus sexmaculatus dan mirid ladybug sebagai dua pemangsa (predator) dimana mangsa dikontrol oleh pestisida. Interaksi antara predator dan prey dimodelkan menggunakan fungsi respon Holling tipe II sedangkan pertumbuhan predator dan prey dimodelkan menggunakan fungsi logistik. Dari model tersebut diperoleh delapan titik ekuilibrium. Tiga titik ekuilibrium dari titik-titik equilibrium tersebut dianalisis menggunakan metode linierisasi dan bersifat stabil asimtotik lokal. Kemudian model ini diaplikasikan pada data. Untuk memudahkan interpretasi antara mangsa dan dua pemangsa dilakukan simulasi numerik untuk memprediksikan dinamika populasi wereng dan predatornya. Hasil simulasi menunjukkan bahwa semua populasi tersebut akan bertahan hidup karena dipengaruhi oleh kontrol pestisida dan tingkat pemangsaan.Kata Kunci: kontrol pestisida; model predator-prey; Holling tipe II; fungsi logistik.

“…Based on the National Law No. 12, 1992 on Plant Cultivation System, Indonesia has adopted integrated pest management (IPM) as a new pest control strategy (Indiati and Marwoto, 2017). Entomological Society of America (2017) defines the IPM as "a science-based approach that combines a variety of techniques.…”

“…3 of 1986 was issued to ban the use of 57 insecticide formulations of 28 active ingredients in rice plantations. The banned insecticides had been proven to trigger pest resurgence due to the death of the natural enemies and the development of resistant pest populations against the insecticides (Indiati and Marwoto, 2017). To facilitate IPM technology transfer and decision making by farmers themselves in managing their plantations, Integrated Pest Management-Farmer Field School (IPM-FFS) models were introduced (Dani et al, 2016).…”

The study examined the adoption levels and economic benefits of IPM among rice farmers in South Sulawesi Province, Indonesia. The research was conducted in two main rice producing areas of the province, Soppeng and Maros Regencies. Simple random sampling was employed in selecting 20% of the total populations, resulting in sample sizes of 69 repondents in Soppeng and 52 respondents in Maros. A structured questionnaire was used in direct interview with the selected respondents to obtain data on their socio-economic profile, IPM implementation, and profit gained from IPM. Percentage was used to present the data. In both regencies, overall IPM adoption rates were high with most respondents were categorized as medium and high IPM adopters with adoption rates of 85.1% in Soppeng and 88.5% in Maros. The medium and high IPM adopters gained more economic profits of 26.9% in Soppeng and 16%% in Maros in comparison to the low IPM adopters. The high adoption rates indicated that although the nationwide IPM Program has ended in late 1990’s, there was a continuous technological transfer from older farmers who participated in IPM-FFS to younger farmer generation. In order to improve IPM implementation by the younger farmers, they need to be provided with intensive extension support for IPM innovations.
