Abstract

Rice is a staple food for the people of Indonesia. Even though Indonesia is an agrarian country, Indonesia currently imports rice. In producing rice from rice there are obstacles. One of the main obstacles is post-harvest handling of rice with high yield loss during post-harvest. The amount of post-harvest loss occurs because most farmers still use traditional methods or the handling is not good and right. The purpose of this study was to determine the relationship between the capacity of the grinding machine and the quality of sosoh rice produced by the mill and to know the quality comparison of various types of grinding machine capacity. The research was carried out in the area of ??Wanasari Village, Tabanan-Bali to find out the quality of sosoh rice in the region. Head Rice is broken rice grains, both healthy and defective, which have a size greater than or equal to 6/10 part of the average length size of whole rice grains that can pass through the surface of the indented plate basin with a requirement of 4.2 mm hole size. Rice husk is a protective cover from rice grains which is separated from seeds during the grinding process. In the grinding process, there is rice which remains the husk which is caused by the power / rpm of the grinding machine which is too low because the friction force produced by the engine is not sufficient for the overall release of rice husk

Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan dua faktor perlakuan. Faktor pertama adalah perlakuan uap etanol dengan 4 level konsentrasi; 0%, 10%, 20% dan 30%. Faktor kedua adalah suhu penyimpanan, terdiri dari 2 level; suhu kamar (26 ?) dan suhu rendah 2 ?. Kuntum brokoli sebagai kontrol disiapkan tanpa perlakuan uap etanol dan ditempatkan pada suhu kamar dan suhu rendah. Parameter yang diukur adalah: tingkat pernapasan, kekerasan, warna dan evaluasi sensorik termasuk rasa, warna, bau, kesegaran, dan kerenyahan. Data dianalisis dengan menggunakan analisis varian. Hasil signifikan dari analisis diikuti oleh uji Beda Nyata Terkecil (LSD 5%). Hasil penelitian menunjukkan bahwa konsentrasi uap etanol 10% adalah perlakuan terbaik karena secara efektif dapat mempertahankan tingkat kehijauan brokoli hingga hari ke 5 dengan nilai -6,23 dibandingkan dengan kontrol. Perlakuan uap etanol dan suhu penyimpanan tidak berpengaruh signifikan terhadap tingkat kekerasan kuntum pada tangkai brokoli. Tingkat respirasi dipengaruhi oleh suhu penyimpanan. Pada suhu kamar, konsumsi O2 meningkat hingga hari ke 5 sekitar 102,2 hingga 193,17 ml O2 / kg. Jam, sedangkan pada suhu rendah, konsumsi O2 lebih rendah hingga hari ke 15 sekitar 65,4 hingga 60,4 ml O2 / kg .jam. Evaluasi sensorik menunjukkan bahwa brokoli mempertahankan kualitas hingga hari ke 4 pada suhu kamar, sedangkan di cold storage dapat memperpanjang usia simpan hingga 8 hari. This research aimed to determine the effect of ethanol vapor and storage temperature on quality and shelf life of broccolies. The research used completely randomized design (CRD) with two factors of treatments. The first factor was ethanol vapor treatment with 4 levels of consentrations; 0%, 10%, 20% and 30%. The second factor was the storage temperature, consisting of 2 levels; room temperature (26?) and low temperature 2?. The florets of broccoli as controls were prepared without treatment of ethanol vapor and placed at room temperature and low temperature. The measured parameters were: respiration rate, hardness, color and sensory evaluation includes flavor, color, smell, freshness, and crispness. The data were satistically analysed using analysis of variance. The significant result of the analysis was folowed by the test of Least Significant Difference (LSD 5%). The results showed that ethanol vapor concentration 10% was the best treatment since it could effectively maintain the level of greenness of broccoli by up to the day 5 with a value of -6,23 compared to controls. Ethanol vapor treatment and storage temperatur had no significant effect on the hardness level of the florets on stalk of broccoli. The rate of respiration was affected by storages temperature. At the room temperature, the comsumption of O2 increased until day 5 about 102,2 to 193,17 ml O2/kg.hr while at low temperature, the O2 consumption was lower until day 15 were approximately 65,4 to 60,4 ml O2/kg.hour. Sensory evaluation showed that the broccoli was maintain quality by up to day 4 at room temperature, while in cold storage can extended the shelf life by up to 8 day.
