Abstract

Potensi Halaman Sekolah sebagai Mikrohabitat, serta Persepsi Masyarakat Sekitar Sekolah tentang Undur-undur (Myrmeleon sp.) sebagai Predator di Kec. Campurdarat, Kab. TulungagungArdhanyswariputri, Yanuwiadi, B., Leksono, A.S. Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Brawijaya, MalangABSTRAK Penelitian ini bertujuan untuk mengetahui potensi halaman sekolah sebagai mikrohabitat undur-undur (Myrmeleon sp.) dan mengetahui persepsi masyarakat sekolah dan masyarakat di sekitar sekolah tentang undur-undur (Myrmeleon sp.) sebagai pengendali hayati di Kecamatan Campurdarat Kecamatan Tulungagung. Prosentase halaman sekolah yang dapat digunakan sebagai mikrohabitat undur-undur (Myrmeleon sp.) dapat diukur dengan membandingkan luasan tanah kering gembur dan tidak lembab maupun tanah berpasir pada halaman sekolah dengan seluruh luasan halaman sekolah. Kemudian presentase tersebut dideskripsikan berdasarkan skala estimasi. Adapun pengambilan data dilakukan dengan wawancara secara tertutup melalui questioner kepada responden yang merupakan warga sekolah dan masyarakat sekitar sekolah di Kecamatan Campurdarat. Pengolahan data dilakukan dengan analisis statistic skala lickert (lickert scale). Hasil penelitian menunjukkan bahwa rata-rata prosentase halaman sekolah yang berpotensi sebagai mikrohabitat undur-undur (Myrmeleon sp.) sebesar 19,61%, yang berarti bahwa rata-rata sekolah yang berada di Kecamatan Campurdarat mempunyai pontensi yang sangat rendah sebagai mikrohabitat undur-undur (Myrmeleon sp.). Sedangkan persepsi warga sekolah dan masyarakat di sekitar sekolah berada pada kategori yang cukup. Prosentase pengetahuan responden tentang undur-undur sebagai musuh alami sebesar 53,92%, sikap responden tentang undur-undur sebesar 55,09%, keterampilan responden terhadap hal-hal berkenaan dengan undur-undur sebesar 55,09%, dan persepsi respondent yang lain secara pribadi sebesar 46,55%.

Abstract

ABSTRAK Hama tanaman mengakibatkan hasil produksi padi di Indonesia menurun. Untuk itu diperlukan suatu upaya pengendalian hama tanpa merusak kestabilan lingkungan yaitu dengan memanfaatkan blok refugia. Tujuan dari penelitian ini yaitu untuk mengetahui kelimpahan, diversitas, famili yang mendominasi pada lahan sawah dan blok refugia di setiap fase pertumbuhan padi serta untuk mengetahui efek blok refugia  terhadap hebivora di sawah Kepanjen. Metode koleksi data tentang kunjungan herbivora yang dipakai dalam penelitian ini adalah visual control. Pada pelaksanaannya, pengamatan herbivora dilakukan pada 5 plot yang dibuat di sawah  dan 1 plot blok refugia di pematang sawah tersebut. Jarak pengamat dari plot sawah maupun blok refugia adalah 2 meter dan pengamatan tentang kunjungan herbivora dilakukan selama 15 menit untuk setiap plotnya. Pengamatan dilakukan 3 periode (pukul 08.00-10.00, 12.00-14.00, dan 15.00-17.00) untuk setiap fase pertumbuhan padi dan masing-masing diulang 2 kali. Pengukuran faktor abiotik meliputi suhu, kelembaban udara dan intensitas cahaya. Nilai penting dan indeks diversitas (Shannon-Wienner) dihitung untuk mengetahui analisis struktur komunitas herbivora. Hasil penelitian menunjukkan bahwa kelimpahan herbivora keseluruhan berjumlah 521 individu yang terdiri dari 5 ordo dengan 13 famili. Famili yang memiliki kelimpahan tertinggi di sawah maupun blok refugia yaitu Acrididae. Diversitas herbivora di sawah maupun blok refugia tergolong rendah hingga sedang. Diversitas herbivora tertinggi di sawah yaitu pada pukul 12.00-14.00 WIB sedangkan di blok refugia diversitas tertinggi terjadi pada pukul 08.00-10.00 WIB. Famili yang mendominasi di sawah maupun blok refugia yaitu Acrididae ditandai dengan tingginya INP.   Kata kunci: Herbivora, organik, pengendalian hayati, refugia   ABSTRACT Pests of plants causes  decreasing of rice production in Indonesia. That’s why it required an effort to control pests without harming the environment stability by using refugia. The objectives of this research were to know the abundance, diversity and family that dominate in the crops and in the refugia block in every stage of rice growth and to determine the effects of refugia block to the herbivore population in Kepanjen rice field. The method used to collect the information of herbivore visited both padi plots and refugia plots in this research was visual control. For those purposes, visual control were conducted on 5 plots in rice field and 1 plot in refugia plots. The distance of the observer to each plot was 2 meters and it were conducted for 15 minutes for each plot. Those observations were made in 3 period (08.00 to 10.00, 12.00 to 14.00, and 15.00 to 17.00) for every stage of rice growth and it were repeated 2 times. The measurement of abiotic factors include temperature, air relative humidity and light intensity. The analysis of herbivore community structure was obtained by counting the important value and Shannon–Wienner diversity index). Total abundance of herbivores was 521 individuals consist of 5 orders with 13 families. Families which had the highest abundance in the fields and refugia was Acrididae. Herbivore diversity in the fields and refugia was low to moderate. The highest of herbivore diversity in rice fields was at 12.00 to 14.00 pm while the highest diversity in refugia was at 8.00 to 10.00 pm. Families that dominate in the fields and refugia was Acrididae with high INP value.   Keywords : Biological control,  herbivore, organic, refugia

Abstract

Riparian vegetation habitats in irrigation canals provide various ecosystem regulatory services for human life. One of them was providing a habitat of natural enemies for agricultural pests. This research aims to evaluate the community structure of natural enemies based on the diversity index and abundance value, and riparian vegetation community in the four different categories of tertiary irrigation canals at the Slamet Village rice field. Arthropods were observed using a visual encounter survey and yellow pan trap methods for fifteen days. At the same time, riparian vegetation analysis was also applied by purposive sampling. The results showed that the first location of irrigation canals had the highest Shannon-Wiener diversity index, taxa richness, evenness, and the lowest dominance value of riparian vegetation with respectively 4.97; 37 species; 0.93; and 0.02. Moreover, it was followed by high natural enemy’s taxa richness based on yellow pan trap and visual encounter survey (16 and 28 families), total abundance (554 and 4450 individuals), diversity index (1.83 and 3.67), evenness index (0.77 and 0.68), and low dominance index (0.22 and 0.21). Arthropods that act as natural enemies commonly found in this location came from the Formicidae, Coenagrionidae, and Coccinelidae families, while the most common pests found were from the Acrididae family. The opposite of that, the fourth location had a high dominance index of riparian vegetation (0.15), diversity index of pest (1.83), taxa richness of pest (10 families), and 272 individuals of pest arthropod arthropods. The highest abundance of pests in this location came from the Acrididae, Drosophilidae, Tephritidae, and Aphididae families.
