Perbandingan tumpukan beras Bulog terhadap populasi kutu beras (Sitophilus oryzae L.) dan mutu beras selama masa simpan di Kabupaten Jayawijaya

Abstract

This study was aimed to find out the effect of rice pile on pest population and the quality of rice during storage; find out which pile of Bulog rice produces the populations of Rice Weevil pest the most during storage; find out which pile of Bulog rice that produces the best quality during storage. This research was conducted in the laboratory of STIPER Petra Baliem Wamena and the Faculty of Agricultural, Universitas Gadjah Mada Yogyakarta. The observation was done in 1 year, from March 2019 to March 2020. The materials and tools used are Bulog rice, rice weevil pest, cartons, plastics, digital scales, stationary, and oven. The research method applies a Completely Randomized Design. The treatments are G1: 15 Bulog rice pile; G2: 20 Bulog rice pile; G3: 25 Bulog rice pile. The results showed that: 1) The rice pile affected the pest population and the quality of rice during storage; 2) G3 condition produced more rice weevil population than others; 3) G1 condition produced the highest final weight of rice, the lowest broken rice, the highest intact rice, the lowest water content, and ash content, and the highest fat content, protein content, and carbohydrate content.

Effect of The Drying Time of Unhulled Rice on The Rice Quality of Variety Inpari-7

“…A. H., Harun, N. Y., Bilad, M. R., Afzal, M. T., Parvez, A. M., Roslan, F. A. S., Rahim, S. A., Vinayagam, V. D., & Afolabi, H. K. 2021; Utami & Ulfa, 2022). If the water content of unhulled rice is lower than 14%, the rice grains will easy to break (Mahanani & Inrianti, 2021;Yang, W., Zheng, Y., Sun, W., Chen, S., Liu, D., Zhang, H., Fang, H., Tian, J., & Ye, X., 2020), so rice produced is more in the form of broken rice grains. Meanwhile, if the water content of unhulled rice exceeds 14%, the grinder machine will work very hard, and the resulting bran will clog the sieve holes during grinding, so the rice produced is easily cracked and broken (Kumoro, A. C., Lukiwati, D. R., Praseptiangga, D., Djaeni, M., Ratnawati, R., Hidayat, J. P., & Utari, F. D., 2019; Permatasari, 2020; Tang, Z., Li, Y., Zhang, B., Wang, M., & Li, Y., 2020).…”

Impact of Using Hermetic Packaging and Preservative on Physical Properties of Rice Bran During Storage

“…This indicated that the calcium propionate did not have any capability to protect rice bran from insect attack. According to Mahanani and Inrianti (2021), the population of beetles increased due to storage time dan relative humidity. Pratiwi and Ananda (2021) reported that at a temperature of 20-30 o C and relative humidity of 60-70% the insect (C. ferrugineus) was found grow well and at a temperature of 40 o C and relative humidity of 35% was suppressed and more mortality.…”

Pengaruh Serbuk Daun Jeruk Purut (Citrus hystrix DC.) dan Daun Sirsak (Annona muricata L) sebagai Senyawa Volatil Terhadap Mortalitas Hama Gudang (Sitophilus oryzae L.) pada Beras

“…Pendapat tersebut sesuai dengan pernyataan Hendrival dan Melinda (2017), bahwa kepadatan populasi S. oryzae yang diinfestasikan semakin tinggi dapat menyebabkan semakin tinggi pula persentase kehilangan bobot dan persentase kerusakan beras berlubang akibat serangan S. oryzae. Jumlah populasi hama berkorelasi positif dengan hasil akhir bobot beras, populasi S. oryzae semakin banyak menyebabkan hasil akhir bobot beras menurun (Mahanani dan Inrianti, 2021;Rizal dkk., 2019). KESIMPULAN 1.…”
