Background: Nonalcoholic fatty liver disease (NAFLD) is associated with obesity. Red rice (Oryza nivara) bran is known to contain polyphenol and antioxidants that might be potential in reducing body weight and visceral fat in obese mice and preventing liver steatosis. This study was aimed to prove the effect of oral administration of red rice bran (Oryza nivara) extract on body weight, visceral fat, and liver steatosis amount in obese male Wistar rats.            Method: In this research, the subjects were 36 male obese (Lee index > 0.3) white rats (Rattus norvegicus) Wistar strain, 4-5 months old, divided into two groups. The control group received a placebo and the treatment group received 460mg/200gram red rice bran extract for 5-weeks. Bodyweight, visceral fat, and the amount of liver steatosis were observed. Differences between groups in each variable were analyzed. Results: The weight of the control group and the treatment group was 321.17 ± 19.04 grams and 305.72 ± 12.89 grams (p < 0.05). The visceral fat weight was 3.15 ± 0.34 grams in the control group and 2.99 ± 0.34 grams (p > 0.05) in the treatment group. Liver steatosis amount was 41 ± 18 cells per visual field in the control group, and 21 ± 12 (p < 0.05) in the treatment group. Conclusion: Oral administration of red rice bran extract can reduce body weight and liver steatosis amount in obese Wistar rats. The extract of red rice bran did not have a significant effect in reducing visceral fat.

Konsumsi protein dan karbohidrat dalam bentuk kue kering diharapkan mampu menambah asupan gizi masyarakat. Mocaf (Modified Cassava Flour) menjadi salah satu komoditas lokal yang dapat menggantikan tepung trigu dalam pembuatan kue kering. Walaupun demikian, mocaf mengandung protein yang rendah yaitu 1,2%, sehingga penambahan tepung beras merah (TBM) dapat menghasilkan kue kering dengan mutu yang lebih baik sekaligus mendukung diversifikasi pangan. Penelitian ini bertujuan untuk mengetahui pengaruh formulasi TBM dan mocaf terhadap sifat kimia dan karakteristik sensoris kue kering. Rancangan Acak Lengkap dengan 5 perlakuan untuk perbandingan TBM (g) dan mocaf (g), yaitu 0:100, 25:75, 50:50, 75:25, dan 100:0, dengan 4 ulangan digunakan pada penelitian ini. Parameter yang diamati adalah sifat sensoris dan kimia. Data sifat kimia dianalisis mengunakan sidik ragam, sedangkan data sensoris diolah mengunakan uji Kruskal-Wallis. Hasil penelitian menunjukkan bahwa formulasi TBM dan mocaf berpengaruh tidak nyata terhadap kadar air, abu dan lemak, namun berpengaruh nyata terhadap kadar protein, karbohidrat, serta sifat sensoris hedonik dan mutu hedonik. Perlakuan terbaik diperlihatkan pada formulasi TBM 75 g dan mocaf 25 g yang menghasilkan cookies dengan kadar air 2,16%, kadar abu 1,99%, kadar lemak 14,97%, kadar protein 9,66%, dan kadar karbohidrat 70,27%, sedangkan sifat sensoris hedoniknya untuk warna, aroma, tekstur, dan rasa berada pada kisaran suka. Sifat sensoris mutu hedonik cookies yang dihasilkan adalah berwarna agak coklat, agak beraroma TBM, tekstur renyah dan agak berasa TBM.

Buah pisang adalah bahan pangan yang bergizi, sumber karbohidrat, vitamin dan mineral. Beras merah merupakan bahan pangan yang kaya akan kandungan antosianin. Salah satu bentuk olahan beras merah paling sederhana adalah pembuatan tepung beras merah. Penggunaan dan pemanfaatan pisang dan tepung beras merah menjadi substitusi pengolahan pangan dapat direalisasikan oleh industri-industri yang bergerak pada bidang pangan, salah satunya yaitu industri kukis.Penelitian ini bertujuan untuk menghasilkan produk kukis yaitu almond crispy dengan penambahan pisang dan substitusi tepung beras merah. Rancangan percobaan yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan faktor pertama perbandingan tepung beras merah dan pisang (80% : 20%; 70% : 30% ; 60% : 40%).

Abstract Background Wild rice, including Oryza nivara and Oryza rufipogon, which are considered as the ancestors of Asian cultivated rice (Oryza sativa), possess high genetic diversity and serve as a crucial resource for breeding novel cultivars of cultivated rice. Although rice domestication related traits, such as seed shattering and plant architecture, have been intensively studied at the phenotypic and genomic levels, further investigation is needed to understand the molecular basis of phenotypic differences between cultivated and wild rice. Drought stress is one of the most severe abiotic stresses affecting rice growth and production. Adaptation to drought stress involves a cascade of genes and regulatory factors that form complex networks. O. nivara inhabits swampy areas with a seasonally dry climate, which is an ideal material to discover drought tolerance alleles. Long noncoding natural antisense transcripts (lncNATs), a class of long noncoding RNAs (lncRNAs), regulate the corresponding sense transcripts and play an important role in plant growth and development. However, the contribution of lncNATs to drought stress response in wild rice remains largely unknown. Results Here, we conducted strand-specific RNA sequencing (ssRNA-seq) analysis of Nipponbare (O. sativa) and two O. nivara accessions (BJ89 and BJ278) to determine the role of lncNATs in drought stress response in wild rice. A total of 1246 lncRNAs were identified, including 1091 coding–noncoding NAT pairs, of which 50 were expressed only in Nipponbare, and 77 were expressed only in BJ89 and/or BJ278. Of the 1091 coding–noncoding NAT pairs, 240 were differentially expressed between control and drought stress conditions. Among these 240 NAT pairs, 12 were detected only in Nipponbare, and 187 were detected uniquely in O. nivara. Furthermore, 10 of the 240 coding–noncoding NAT pairs were correlated with genes enriched in stress responsive GO terms; among these, nine pairs were uniquely found in O. nivara, and one pair was shared between O. nivara and Nipponbare. Conclusion We identified lncNATs associated with drought stress response in cultivated rice and O. nivara. These results will improve our understanding of the function of lncNATs in drought tolerance and accelerate rice breeding.

Red rice was one species of rice in Indonesia that was superior in nutritional content and selling price compared to white rice but the productivity of red rice is still low. One of way to improved rice growth and productivity is fertilization red rice was one type of rice in Indonesia that contains high nutrition. This research aimed to observe the effects of  the combination of organic and inorganic fertilizers on the growth and yield of red rice (Oryza nivara L.). The research used a Randomized Completely Block Design (RCBD) with 7 treatments. Each treatment had 3 replications and each experiment unit consisted of 3 plants so that there were 63 plants. The best treatment was compost of oil palm empty fruit bunch (125 g) + N, P, and K fertilizer 50%. The highest production was on oil palm empty fruit bunch compost (125 g) + Fertilizer N, P and K 50%,  it was equivalent to 5.49 ton/ha. In the red rice crop farming system it can be recommended to provide a combination of oil palm empty fruit bunch (125 g) compost and 50% N, P and K fertilizer to increase yields in the cultivation of red rice.

However, the contribution of lncNATs to drought stress response in wild rice remains largely unknown. Results Here, we conducted strand-specific RNA sequencing (ssRNA-seq) analysis of Nipponbare (O. sativa ssp. japonica) and two O. nivara accessions (BJ89 and BJ278) to determine the role of lncNATs in drought stress response in wild rice. A total of 1,246 lncRNAs were identified, including 1,091 coding–noncoding NAT pairs, of which 50 were expressed only in Nipponbare, and 77 were expressed only in BJ89 and/or BJ278. Of the 1,091 coding–noncoding NAT pairs, 240 were differentially expressed between control and drought stress conditions. Among these 240 NAT pairs, 12 were detected only in Nipponbare, and 187 were detected uniquely in O. nivara. Furthermore, 10 of the 240 coding–noncoding NAT pairs were correlated with genes previously demonstrated to be involved in stress response; among these, nine pairs were uniquely found in O. nivara, and one pair was shared between O. nivara and Nipponbare. Conclusion We identified lncNATs associated with drought stress response in cultivated rice and O. nivara. These results will improve our understanding of the function of lncNATs in drought tolerance and accelerate rice breeding.
