The onion waste (Allium cepa L.) is an organic material that can be used as bioethanol as the cleanest liquid fuel. Shallot is a beneficial source of fermented products because it has a high sugar content and contains various nutrients such as carbohydrates, proteins, fats and cellulose as the main components of biogas production, but shallot waste has a relatively low C/N. Livestock manure also contains nutrients and contains organic matter which is shown by the average yield of C/N vermicompost from buffalo manure higher than vermicompost from cow manure but statistically shows the C/N ratio of vermicompost from cow manure and buffalo is not significantly different. Red onion and buffalo dung waste can be processed into basic materials with the potential to produce biogas, but now the onion waste and buffalo dung farming is a serious problem in the Lembah Gumanti Subdistrict, Solok Regency because it has not been properly treated as a source of environmental pollution. The research was conducted in December 2018 - January 2019 at the State University of Padang. The purpose of this study was to determine the potential mixture of onion waste (Alium cepa L.) and buffalo dung as biogas producers. With 5 different compositions and treatments A 25% waste red onion saturated with water 75% buffalo dung, B 50% red onion waste saturated with 50% water buffalo dung, C 75% waste onion leaves saturated with 25% water buffalo dung , D of buffalo dung and E of saturated red onion leaf waste from the treatment obtained by the third treatment has the best potential for producing biogas among the four other treatments. Keywords: Red onion waste (Allium cepa L.), Buffalo dung, biogas.

Genotype by environment (GE) interaction and genotype stability of a trait in rice (Oryza sativa L.) are very important for plant breeders in making decision regarding the development and evaluation of new cultivars as well as for farmers in selecting suitable cultivars to be planted for commercial purpose. Yield components including panicles number plant–1, number of grains panicle–1, 1000-grain weight, and grain yield of five locally adapted cultivars of rice were evaluated at three locations in West Sumatera. The data were used to determine GE interaction variance components and stability of the traits. There were significant effects of locations on yield and some yield components except number of panicles plant–1. The cultivars differed significantly in all yield components but not in grain yield. The influence of GE interaction was highly significant on all yield components and grain yield. The magnitude of GE interaction variance component was greater than that of location for all traits. These data suggested that genotypes performed differently among the locations and were not stable with respect to the locations, so that farmers should select a suitable cultivar to be grown in the area of production.

Batok glutinous rice especially local varieties, is one of the agricultural commodities that can be used as a source of food. Besides having a good taste, batok glutinous rice is also not easily attacked by pests and rice seeds easily obtained. However, obstacles in the utilization of glutinous rice for local varieties are long harvest time and low production. Therefore, seed priming is carried out by utilizing biofertilizer derived from the rhizosphere fungus, Trichoderma spp. Trichoderma is a function that is classified as Plant Growth Promoting Function (PGPF) which is able to stimulate plant growth by producing growth regulators. This study aims to determine the response of the germination of batok glutinous rice seeds against of Trichoderma spp.This research is an experimental study using a completely randomized design with 7 treatments and 3 replications. The treatment given was soaking seeds with 6 types of Trichoderma spp. isolates and 1 control soaked with aquadest. The data obtained were analyzed statistically using ANOVA. If there are significant differences, further tests of DMRT are carried out with α = 5%.The results obtained indicate that Trichoderma spp. no significant effect on the percentage of germination and vigor index, but significant effect on the germination speed with RE isolates is the best isolate in increasing the seed germination speed.Beras ketan Batok khususnya varietas lokal, merupakan salah satu komoditas pertanian yang dapat dimanfaatkan sebagai sumber pangan. Selain memiliki rasa yang enak, beras ketan batok juga tidak mudah terserang hama dan bibit padi mudah didapatkan. Namun kendala dalam pemanfaatan beras ketan untuk varietas lokal adalah waktu panen yang lama dan produksi yang rendah. Oleh karena itu, priming benih dilakukan dengan memanfaatkan pupuk hayati yang berasal dari cendawan rizosfer Trichoderma spp. Trichoderma merupakan fungsi yang tergolong Plant Growth Promoting Function (PGPF) yang mampu merangsang pertumbuhan tanaman dengan memproduksi zat pengatur tumbuh. Penelitian ini bertujuan untuk mengetahui respon perkecambahan benih ketan batok terhadap Trichoderma spp. Penelitian ini merupakan penelitian eksperimen dengan menggunakan rancangan acak lengkap dengan 7 perlakuan dan 3 ulangan. Perlakuan yang diberikan adalah perendaman benih dengan 6 jenis Trichoderma spp. isolat dan 1 kontrol direndam dengan aquadest. Data yang diperoleh dianalisis secara statistik menggunakan ANOVA. Jika terdapat perbedaan yang signifikan, selanjutnya dilakukan uji DMRT dengan = 5%. Hasil yang diperoleh menunjukkan bahwa Trichoderma spp. tidak berpengaruh nyata terhadap persentase daya berkecambah dan indeks vigor, namun berpengaruh nyata terhadap kecepatan berkecambah dengan isolat RE merupakan isolat terbaik dalam meningkatkan kecepatan berkecambah benih.

Publisher : UNIVERSITAS NEGERI PADANG

The curd is a traditional food Minangkabau in West Sumatra. This product is made from buffalo milk made with buffalo milk entering into the bamboo and covered with banana leaves and left at room temperature for about 1 to 2 days. Due to the limited availability of buffalo milk, buffalo milk is replaced with cow's milk. Obstacles encountered in the development of the curd is curd less flavorful savory and original taste sour curd so that the public interest is reduced. Therefore, we need a way to neutralize the smell and taste of sour curds, one of which is the juice of mango (Mangifera indica). The purpose of this study was to determine the effect of mango juice and long ripening on the quality of cow's milk curd. This study is experimental and descriptive. The design used was a 3x2 factorial randomized block design with three replications. A factor is the mango juice consisting of 3 treatment, and long ripening factor B is composed of 2 treatments. Research was conducted in January 2016 in the Laboratory of Livestock Product Technology Faculty of Animal UNAND. Parameters measured were total acid content, protein content, and organoleptic. Data were analyzed by descriptive qualitative analysis of variance (ANOVA) and a further test DNMRT at 5% level. The results of this study are the addition of mango juice and long curing does not affect the total acid content (% TAT). However, the addition of mango juice and long curing effect on protein levels although there is no interaction between the concentration and duration of ripening. Lowest total acid level was the control treatment on a long curing 48 hours and total acid concentration is the highest concentration of 3% at 36 hours. Lowest protein content that is the control treatment at 36 hours and the highest concentration of 3% at 48 hours. The results of organoleptic tests show the variation of each treatment. Keyword: cow's milk curd, mango juice, total acid content, protein content, organoleptic.
