Abstract

This research was carried out at the Perum Kupang Warehouse, East Nusa Tenggara with aimed to determine the effectiveness of aluminum phosphide in controlling Rhyzoperta dominica in the Bulog Perum warehouse. This study was arranged in a completely randomized design (CRD) method with 5 treatment doses and each treatment was repeated five times. The variables observed were mortality symptoms of R. dominica, mortality of R. dominica treated with aluminum phosphide and rice loss. The results showed that the mortality of R. dominica treated with aluminum phosphide showed symptoms of body shrinkage as it gradually dried and became stiffer. Aluminum phosphide fumigant was toxic to R. dominica imago and each treatment had different level of toxicity. At doses of 8 g ton-1 and 18 g ton-1 of Aluminum phosphide fumigant, it could kill R. dominica imago ≥95%. The results of probit analysis showed that aluminum phosphide could kill 50% of the tested insects at a dose of 6.33 g ton-1 (LD50) and 18.37 g ton-1 (LD90) at one week after treatment (WAT), while at four WAT, at a dose of 1.28 g ton-1 (LD50) and 8 g ton-1 aluminum phosphide could kill 50% and 95% of insects tested, respectively. There was no rice shrinkage observed in each treatment, this is presumably because on the first day of weighing R. dominica imago had been exposed to phosphine gas and at one WAT the insects were removed from the sample sack and then transferred to a new container to observe weekly mortality.

Abstract

Pisang merupakan salah satu tanaman asli Indonesia yang terdiri atas jenus dan kultivar yang sangat beraneka ragam yang secara tradisional telah dibudidayakan secara luas di Indonesia, termasuk di Desa Buraen, Kabupaten Kupang, Provinsi Nusa Tenggara Timur. Tujuan kegiatan ini untuk memberikan informasi mengenai cara mengidentifikasi dan mengendalikan hama dan penyakit serta cara memanfaatkan pisang sebagai sumber pendapatan kepada masyarakat petani di Desa Buraen, Kabupaten Kupang, Provinsi Nusa Tenggara Timur. Untuk mencapai tujuan kegiatan pengabdian pada masyarakat tersebut, maka dilakukan penyusunan berbagai panduan mengenai hama, penyakit, pengendalian dan pemanfaatan tanaman pisang sebagai sumber pendapatan rumah tangga. Pendekatan metodologis dalam PKM ini menggunakan pendekatan keanekaragaman hayati dan ketahanan hayati dengan menggunakan langkah 5-D, sebagai berikut: (1) mendefinisikan tujuan (definition), (2) penemuan potensi positif (discover), (3) perumusan visibersama (dream), (4) perancangan kegiatan (design), dan (5) penyiapan pelaksanaan kegiatan (destiny) yang saling berkaitan satu sama lain dengan memberikan penyuluhan serta praktek mengenai berbagai olahan dari pisang. Hasil evaluasi pelaksanaan kegiatan PKM ini yang diberikan melalui formulir evaluasi yang dibagikan kepada peserta pada awal kegiatan, terdapat 50 % peserta belum mengenal dan mengetahui informasi mengenai cara mengidentifikasi dan mengendalikan hama dan penyakit serta cara memanfaatkan pisang sebagai sumber pendapatan dan setelah kegiatan dengan merujuk kepada jenis luaran dan indikator capaian yang telah ditetapkan, terdapat 100 % peserta sudah mengenal dan mengetahui jenis hama, penyakit dan manfaat pisang sebagai sumber pendapatan.

Abstract

This study aimed to determine the S. oryzae imago number and the level of damage intensity it caused on grains of several rice varieties in Mauponggo District, Nagekeo Regency. The study was conducted at the Pest Laboratory of the Faculty of Agriculture, Nusa Cendana University. The study was laid out in a completely randomized design consisting of five rice varieties as treatments, each was four replicates. A rice grain of 100 grams was put into a plastic jar and infested with a uniform five pairs of S. oryzae. Observed variables included grain water content, number of S. oryzae imago and the percentage of grain weight loss as a measure of damage intensity. Data were subjected to analysis of variance, followed by an Honest Significant Post hoc test at a 0.05 % significance level. The study results showed significant differences among tested rice varieties in both imago populations as well as the level of grain weight loss. IR 64 variety showed the lowest number of imago of S. oryzae and also the lowest grain weight loss while local red and black rice were the highest in both the number of imago and grain weight loss at eight weeks after S. oryzae infestation.
