Abstract

The use of traps to control lowland rats. The lowland rat (Rattus rattus argentiventer ) is one of the importance pests of rice in Indonesia. The rat may cause serious damage on rice and other crops. This study was aimed to determine the affectivity of rat trappings. Traps were set in Pekalongan Central Lampung, from October to December 2002. The treatments were arranged in a factorial experiment in randomized complete block design. The first factor was the type of traps (bamboo trap and wired “bubu” trap) while the second factor was the location of traps (rice field, swamp, tertiary irrigation canal, and rice plot borders). The catches show that there were no interaction between the trap type and trap location. In addition, more rats were caught in bamboo than those in wired “bubu” trap. The highest number of rat catches was from the swamp area.

Abstract

The diversity and abundance of Collembola and soil arthropods in organic and conventional lowland field at fallow time. As ecosystem components, Collembola and arthropods are important in keeping the ecosystem stability. Beside its role as the decomposer, Collembola also takes part as the alternative food for arthropod predators. This research was aimed to gather information on the diversity and abundance of Collembola and arthropods in organic and conventional lowland field at fallow time. The sampling was done using pitfall trap and Berlese funnel. The results showed that: (1) the abundance of Collembola in organic lowland field was higher than that of in the conventional lowland field but the diversity of Collembola in the organic lowland field was not different from that of in the conventional field; (2) Entomobryidae was the family with the highest abundance; and (3) the diversity and abundance of soil arthropods were relatively greater in organic lowland field than that of in the conventional lowland.

Abstract

Arbuscular mycorrhizal fungi (AMF) are beneficial microbes for plants, especially in the absorption of nutrients and water from the soil. Some factors that influence the effectiveness of this fungus are the suitability of the AMF species with their host plants and abiotic condition such as soil characteristics. Therefore, this study aims to determine the type of AMF that produced the best growth and nutrient uptake in oil palm seedlings planting in histosol soil. This study used a single factor treatment design consisting of 9 AMF treatments, namely control without AMF (T1), given Glomus sp. (T2), Gigaspora sp. (T3), Entrophospora sp. (T4), Acaulospora sp. (T5), a mixture of Glomus sp. and Gigaspora sp. (T6), a mixture of Glomus sp. and Entrophospora sp. (T7), a mixture of Gigaspora sp. and Entrophospora sp. (T8), and a mixture of Glomus sp., Gigaspora sp., Entrophospora sp., and Acaulospora sp. (T9). Each treatment was repeated five times. The experimental design used was a randomized block design. In the AMF treatment, 500 spores per seedling were given when the seedlings were transplanted from prenursery to the main nursery. The seedlings were kept in the prenursery for 3.5 months and in the main nursery for nine months. The results showed that the type of mycorrhizal that consistently produced better seedling growth and nutrients uptake compared to the control were Glomus sp. (T2) and a mixture of Gigaspora sp. and Entrophospora sp. (T8), which supported by data on plant height, number of leaves, shoot dry weight, and total nutrient uptake of N, P, K, Ca, Mg, and B.

Abstract

Penelitian ini bertujuan untuk mengetahui keanekaragaman arthropoda permukaan tanah pada pertanaman ubikayu setelah perlakuan olah tanah dan pengelolaan gulma. Perlakuan disusun dalam rancangan acak kelompok (RAK) dengan empat perlakuan dan empat ulangan. Keempat perlakuan tersebut ialah olah tanah minimum dan pengelolaan gulma secara manual (non herbisida), olah tanah minimum dan pengelolaan gulma dengan herbisida, olah tanah intensif dan pengelolaan gulma dengan herbisida, serta olah tanah intensif dengan pengelolaan gulma non herbisida. Herbisida yang digunakan berbahan aktif glifosat dan 2,4 D dengan dosis 160 ml Bimastar 240/120 SL dalam 1 liter air per ha diaplikasikan pada awal tanam. Pengambilan sampel arthropoda dengan pitfall trap (diameter 9 cm, tinggi 12 cm) dilakukan sebanyak 8 kali dengan selang waktu 1 minggu. Hasil penelitian menunjukkan bahwa kemelimpahan total arthropoda permukaan tanah pada lahan pertanamanubikayu dengan perlakuan pengolahan tanah dan pengelolaan gulma ialah sebanyak 8910 ekor, yang tercakup dalam 10 ordo dan 27 – 29 famili. Diantara ordo dan famili yang diperoleh, dua ordo dan famili dengan kemelimpahan dan kepadatan populasi relatif tertinggi berturut-turut ialah ordo Collembola dan Hymenoptera, serta famili Paronellidae dan Formicidae. Baik perlakuan pengolahan tanah maupun pengelolaan gulma yang dilakukan pada awal tanam tidak berpengaruh terhadap keanekaragaman arthropoda. Besarnya nilai-nilai indeks Shannon-Wiener dan indeks Simpson tergolong dalam kategori sedang. Selain itu juga diketahui bahwa pada keseluruhan lahan perlakuan, arthropoda permukaan tanah yang didapatkan didominasi oleh arthropoda yang berperan sebagai dekomposer dan predator.

Abstract

Kajian jenis dan populasi tikus merupakan tahapan dasar yang sangat penting sebelum dilakukannya manajemen pengendalian hama. Informasi yang diperoleh dapat menjadi dasar pertimbangan dalam menentukan strategi pengendalian tikus yang efektif. Penelitian ini dilakukan untuk mempelajari jenis dan populasi tikus, serta intensitas serangan tikus di perkebunan nanas PT Great Giant Food (GGF). Penelitian dilakukan di perkebunan nanas PT GGF Terbanggi Besar, Lampung Tengah pada bulan Juni sampai dengan Agustus 2016. Penelitian ini menggunakan teknik survei purposive sampling dengan empat blok kebun yang dipilih sebagai sampel yaitu blok kebun yang berbatasan dengan perkebunan tebu PT GMP, berdekatan dengan gedung dan kantor, berdekatan dengan desa, dan blok kebun yang jauh dari perbatasan maupun gedung. Penelitian dilakukan menggunakan metode perangkap (trapping), berbentuk persegi panjang dengan ukuran p x l x t = 30 cm x 20 cm x 15 cm. Jumlah tikus terperangkap dan intensitas serangan dianalisis nilai tengah standar errornya. Populasi relatif dihitung dari presentase setiap jenis di tiap blok, sedangkan nisbah kelamin dihitung dengan membandingkan jumlah jantan/betina. Hasil penelitian menunjukkan bahwa terdapat dua jenis tikus yaitu Rattus argentiventer dan Rattus exulans. Populasi relatif tikusspesies Rattus argentiventer yaitu 66,7% sedangkan spesies Rattus exulans yaitu 33,3%. Intensitas serangan tikus tertinggi terdapat pada blok kebun yang berbatasan dengan perkebunan tebu PT GMP 0,68% dan intensitas serangan tikus terendah pada blok kebun yang jauh dari perbatasan dan bangunan 0,22%.
