Abstract
Sistem pertanian padi kompleks atau biasa disebut dengan Complex Rice System (CRS) merupakan sebuah inovasi dalam bertani tanaman padi yang di dalamnya diterapkan perpaduan dari berbagai macam faktor pada lahan, seperti tanaman air, hewan ternak, dan tanaman pinggiran lahan sehingga mampu menciptakan keanekaragaman biodiversitas yang mampu mendukung keseimbangan dalam ekosistem sehingga akan memunculkan potensi dalam menghadirkan serangga musuh alami seperti parasitoid yang mampu mengendalikan populasi hama pada lahan. Maka melalui penelitian ini dilakukan sebuah pengamatan terhadap jenis penerapan sistem pertanian terpadu, baik dari sisi habitat dan juga faktor lain seperti suhu dan kelembapan yang ada terhadap dampaknya dalam dinamika keragaman spesies dan kelimpahan individu dari parasitoid pada lahan. Penelitian ini berlokasi di Desa Sukorejo Kab. Malang, mengambil sampel pada tiga titik lahan dengan perlakuan padi+bebek+azolla+tanaman para-para labu dan non-para timun untuk plot pertama. Perlakuan padi+bebek+azolla+tanaman para-para labu, tomat, timun dan non-para kacang bambara dan kenikir untuk plot kedua. Perlakuan konvensional monokultur untuk plot pengamatan ketiga. Pengambilan sampel parasitoid dilakukan dengan menggunakan dua jenis perangkap, yakni perangkap likat kuning dan perangkap umpan kepiting. Kemudian data hasil pengamatan terhadap perbedaan antar perlakuan dianalisis menggunakan analisis kesamaan guna mengetahui komposisi parasitoid yang ada, kemudian dilakukan analisis ragam guna mengetahui dampak dari faktor-faktor penting dalam lingkungan pertanian dalam memengaruhi dinamika parasitoid, serta analisis regresi guna mengetahui pengaruh suhu dan kelembapan terhadap keanekaragaman dan kelimpahan populasi parasitoid pada lahan. Berdasarkan hasil pengamatan, ditemukan sebanyak 14 Morfospesies parasitoid yang memiliki potensi sebagai agens hayati dalam mengendalikan populasi hama yang ada pada lahan. Terdapat 5 Morfospesies terbanyak yang berasal dari ordo Hymenoptera yakni Ichneumonidae sp.1, Ichneumonidae sp.2 dan Ichneumonidae sp.3 sebagai parasitoid larva. Serta parasitoid Trichogramma sp. dan Telenomus sp. yang berperan menjadi parasitoid telur dari hama yang ada pada lahan seperti walang sangit, wereng batang cokelat dan penggerek batang padi kuning. Selain itu terdapat juga parasitoid lain dari ordo Diptera (lalat-lalatan) seperti Tachinidae sp., Pipunculidae sp. dan Conopidae sp. yang berperan dalam mengendalikan serangga hama pada lahan. Dari hasil penelitian, menunjukan bahwa perbedaan sistem padi kompleks tidak memiliki pengaruh terhadap keanekaragaman spesies dan kelimpahan individu parasitoid serta adanya perbedaan komposisi spesies pada perlakuan sistem padi kompleks yang berbed
English Abstract
The Complex Rice System (CRS) is an innovation in rice farming which combined various factors inside the system, such as water plants, livestock animals, and landside-plants so as to create greater biodiversity on the habitat. This system able to support the balance of ecosystem so that it’ll bring up the potential in presenting natural enemies like parasitoid that are able to control the pest population on land. Through this research an observation was made by observing the integrated farming system, both in terms of habitat and also other factors such as temperature and humidity that exist on the impact on the dynamics of species diversity and individual abundance of parasitoid on the land. This research took location in Desa Sukorejo Kab. Malang, sampling are located at three points observation land with the treatment of rice+duck+azolla+staked pumpkin and non-staked cucumber for the first plot. Treatment of rice+duck+azolla+staked plants like squash, tomatoes, cucumbers and non-stake plants such as ground nuts and marigolds for the second plot. Monoculture conventional treatment for the third observation plot. Sampling of parasitoid was carried out using two types of traps namely yellowsticky traps and crab bait traps. Then the observed data on differences between treatments were analyzed using analysis of similarity method to determine the composition of existing parasitoid, analysis of variance to determine the impact of important factors in the agricultural environment in influencing the dynamics of parasitoid, and the regression analysis to determine the effect of temperature and humidity on the diversity and abundance of parasitoid populations in the field. Based on the observations, it was found that 14 morphospecies of parasitoid had potential as biological agents in controlling pest populations in the field. There are 5 most morphospecies from the Hymenoptera order, namely Ichneumonidae sp.1, Ichneumonidae sp.2 and Ichneumonidae sp.3 as larval parasitoids. As well as the parasitoid Trichogramma sp. and Telenomus sp. which acts as egg parasitoid of pests that exist in the field such as rice bugs, brown planthopper and yellow stem borer. Apart from that, there are also other parasitoids from the order Diptera (flies) such as Tachinidae sp., Pipunculidae sp. and Conopidae sp. which plays a similar role in controlling insect pests in the field. From the results of the research, it shows that the differences of the treatment that applied in this observation wasn’t have an influence on species diversity and abundance of individual parasitoid as well as differences in species composition in different complex rice system treatme
