Abstract

      The purpose of this study was to obtain production time efficiency on the MIFRA®22 nutmeg pericarp grater. Research at the Agricultural Engineering Laboratory, Faculty of Agriculture, UNSRAT Manado. The research period starts from March 25 to April 30, 2022. This study was designed using a completely randomized design (CRD) method with 3 treatments and 4 replications. Treatment consists of: 1). The interval of grating duration is 10 minutes, 2). The interval of grating duration is 15 minutes, and 3). The interval of grating duration is 20 minutes. Each time interval is repeated 4 times. Grated using a nutmeg pericarp grater MIFRA®22 roller grater with 250 blades. Data were tabulated and analyzed using One-way ANOVA Confidence Interval 95% and continued with 5% BNJ test (Pongoh et al, 2022). The results of calculating the best efficiency were obtained in the treatment duration of 15 minutes with an average grating time of 81.5 seconds. The calculation of the pericarp weight of grated nutmeg resulted in an average weight of 435 grams. Calculation of the weight of the flesh of nutmeg is not shredded with an average weight of 65 grams. The percentage efficiency of grating time with an average of 84.92%.

Abstract

 Insects are one part of the biodiversity that exists on this earth. Insect species and populations have a very important impact on stability in the lowland rice ecosystem.  The sedated insects are placed on white paper and then counted in numbers and put in a collection bottle containing alcohol and labeled on the bottle.  The things that were observed were the type and population of insect pests.  The results of observations of the types and populations of insect pests found in the village of Mogoyunggung District Dumoga Bolaang Mongondow district found 6 (six) types of insect pests.  In the vegetative phase found 5 (five) types of insects namely Scotinophara coartata, Paraeucosmetus pallicornis, Sogatela furcifera, Oxya sp. and Scirpophaga innotata, while the generative phase of the insect species found were Leptocorisa oratorius, S. coartata, P. pallicornis, S. furcifera, and Oxya sp. Keywords:  Diversity; insect; pests; Oryza sativa L  AbstrakSerangga merupakan salah satu bagian dari keanekaragaman hayati yang ada dimuka bumi ini.  Jenis dan populasi serangga memiliki dampak yang sangat penting bagi kestabilan di dalam ekosistem padi sawah. Indeks keanekaragaman  dapat digunakan untuk menyatakan hubungan kelimpahan spesies dalam suatu komunitas. Penelitian bertujuan mengetahui jenis, populasi dan keanekaragaman serangga hama pada tanaman padi di Desa Mogoyunggung, Kecamatan Dumoga Timur, Kabupaten Bolaang Mongondow.  Serangga yang telah terbius diletakkan pada kertas putih kemudian dihitung jumlahnya dan dimasukkan dalam botol koleksi yang berisi alkohol dan diberi label pada botol tersebut.  Hal-hal yang diamati yakni jenis dan populasi serangga hama yang terjaring dalam net serangga.  Hasil pengamatan jenis serangga hama di Desa Mogoyunggung Kecamatan Dumoga Kabupaten Bolaang Mongondow ditemukan 6 (enam) jenis serangga hama.  Pada fase vegetatif ditemukan 5 (lima) jenis serangga yakni Scotinophara coartata (kepinding tanah), Paraeucosmetus pallicornis (kepik hitam), Sogatela furcifera (wereng punggung putih), Oxya sp. (belalang) dan Scirpophaga innotata (penggerek batang putih), sedangkan fase generatif jenis serangga yang ditemukan yaitu Leptocorisa oratorius (walang sangit), S. coartata (kepinding tanah), P. pallicornis (kepik hitam), S. furcifera (wereng punggung putih), dan Oxya sp. (belalang).Kata Kunci:  Keanekaragaman; serangga; hama; Oryza sativa L.
