Abstract

Solusi bijak untuk mengatasi kekurangan beras adalah dengan memaksimalkanproduksi beras dalam negeri, diantaranya dengan menekan susut pasca panen dan meningkatkan rendemen giling. Penelitian ini bertujuan untuk mengkaji teknik penanganan pascapanen terutama perontokan dan penggilingan padi varietas Ciherang, Hibrida, dan Cibogo. Perontokan padi dilakukan dengan tiga metode perontokan: (i) digebot; (ii) pedal thresher; dan (iii) power thresher. Penggilingan padi dilakukan menggunakan tiga konfigurasi penggilingan mesin yang berbeda: (i) dua kali pecah kulit dan dua kali sosoh (2H-2P); (ii) satu kali pengupasan kulit, satu kali pengayakan (separator), dan satu kali penyosohan (H-S-P); dan (iii) satu kali pengupasan kulit, dua kali pengayakan dan dua kali penyosohan (H-2S-2P). Hasil penelitian menunjukkan bahwa jumlah butir gabah per malai pada varietas hibrida adalah 303 butir, paling tinggi diikuti ciherang (158 butir) dan cibogo (130 butir). Namun demikian, varietas hibrida memiliki berat seribu butir paling rendah (28,6 g) dibandingkan ciherang (29,7 g) dan cibogo (30,4 g). Penggunaan power thresher mampu menekan susut perontokan dari 3,31–4,35 persen (dengan alat gebot) menjadi 0,49–1,21 persen dan menghasilkan gabah dengan persentase keretakan butiran gabah yang paling rendah. Rendemen giling padi varietas cibogo (67,81 persen) lebih tinggi dibandingkan varietas ciherang (62,61 persen) dan hibrida (60,78 persen). Konfigurasi penggilingan H-2S-2P menghasilkan susut penggilingan terendah yaitu 2,52 persen dan mampu meningkatkan derajat sosoh dan tidak mempengaruhi rendemen giling. The best solutions to overcome the shortage of national rice production is by applying good postharvest handling practices to reduce losses and increase the milling yield. This study aims to assess postharvest handling of several varieties of paddy, especially threshing and milling. Threshing of paddy is done by three methods: (i) manually or “gebot”; (ii) using pedal threshers; and (iii) using power threshers. Milling of rice is done using three milling configurations: (i) twice paddy husking and twice rice polishing (2H-2P); (ii) once paddy husking, once paddy separation and once rice polishing (HSP); and (iii) once paddy husking, twice paddy separation and twice rice polishing (H-2S-2P). The results show that the highest number of grains per paddy panicle is 303 grains for Hybrid varieties followed by Ciherang (158 grains) and Cibogo (130 grains). However, Hybrid variety has the lowest weight of thousand grains (28.6 g) compared to Ciherang (7.29 g) and Cibogo (4.30 g). The use of power thresher is able to reduce paddy losses from 3.31 to 4.35 percent (for manual threshing or gebot) to be 0.49 to 1.21. The use of power thresher also reduces the percentage of grain cracking. The milling yield of Cibogo variety is the highest (67.81 percent) compared to Ciherang variety (62.61 percent) and Hybrid variety (60.78 percent). Milling configuration of H-2S-2P is the best performance of rice milling processing; resulting the lowest milling losses (2,52 percent) and increasing the polish degree (100 percent) and does not affect the milling yield of rice (66,22 percent).

Abstract

Rice is the staple food for Indonesian people so that the rice supply will be the barometer for thenational’s food security. In rice production, both of postharvest losses and low milling yield are still theproblems due to lack of postharvest handling. In this study, the effect of rice milling machine configurationon the milling yield and quality of some paddy varieties was examined. Paddy variety of Ciherang, Cibogoand Hybrid were milled using a configuration process of: 1) two husking and two polishing (2H-2P), 2) onehusking, one separating and one polishing (H-S-P), and 3) one husking, two separating and two polishing(H-2S-2P). The results show that the paddy varieties significanly affect milling yield and losses. However,rice milling machine configurations are not significantly affect the milling yield and losses. Paddy variety ofCibogo resulting in the highest milling yield (67.80 %) compared to Ciherang (62.61 %) and Hibrida (60.78%). Paddy variety of Cibogo resulting in the lowest losses (1.41 %) compared to Ciherang (3.43 %) andHibrida (3.03 %). The speed of milling process for configuration of 2H-2P, H-S-P and H-2S-2P were 228.1kg/hour, 295.6 kg/h and 263.2 kg/hr respectively.Keywords: paddy, rice milling configuration, milling lossess, milling yieldDiterima: 30 Juni 2009; Disetujui: 19 Oktober 2009
