Abstract

               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.

Abstract. Birds bodiversity affected by habitat conditions and the human activity, as well as bird diversity in Padang State University campus. Padang State University campus is currently experiencing physical changes due to the construction and renovations carried out in seven faculties which have resulted in the loss of green areas which are actually habitat for birds. Previously there was no research on the birds on the UNP campus before there were renovations and construction on the UNP campus. This research was conducted from January to March 2019. Observations were made using the Visual Ecounter Survey (VES) method and combined with the count point method (Point count). Observations are made in the morning (6:00 - 09:00 WIB) and in the afternoon (16:00 - 18:00 WIB). The results of this study indicate that there were 21 species of birds from 15 families. The birds that dominate at the UNP campus area are the genus Passer and Lonchura. While birds that are rarely observed are genera Nectarinia, Copsychus and Eudynamys. The location of the UNP campus adjacent to the beach is also one of the factors that influence the diversity of bird species in this area, as evidenced by the presence of the Ardea sumatrana Cangak laut water bird species. kata kunci: UNP campus, birds, conservation, inventory.

Abstract

Fluorescent pseudomonads are biological agents that live in the soil around the roots which can increase plant growth. Compatible fluorescent pseudomonad is a combination of fluorescent pseudomonads, which aims to make the two bacteria function better in increasing plant growth. The aim of the study was to see the compatibility of several fluorescent pseudomonad isolates and to obtain the best fluooresen pseudomonad in improving the growth of tomato tannins (Lycopersiconesculentum Mill.). This study was an experimental study, using a randomized block design (RAD) with six treatments and three replications. The treatment is a combination of PfPb3 isolates with PfCas; a combination of PfCas isolates with LAHLS1 isolates; the combination of PfPj2 isolates with LAHLS1 isolates; combination of PfPj2 isolates with PfPj1 isolates; combination of PfPj2 isolates with LAHLS1 isolates and a combination of LAHLS1 isolates with PfKd7 isolates. The parameters observed were plant height. Data were analyzed using Analysis of Variance (ANOVA) test and not continued with DNMRT further test at the level of 5%. The results obtained by all compatible fluoreesene pseudomonad isolates can increase the height of tomato plants (Lycopersiconesculentum Mill.).

Abstract

Abstract. Pakcoy (Brassica chinensis L.) is a type of vegetable consumed by many people because of its high nutritional content. The obstacle in producing pakcoy is that the land for farming decreases as population growth grows. One way to overcome this is to plant hydroponics by utilizing cow urine as nutrition. This study studied liquid nutrients made from cow urine (Bos taurus) as hydroponic nutrition in the growth of Pakcoy (Brassica chinensis L.) plants. This research is an experimental study. The design used was a completely randomized design with 5 assemblies and 4 replications namely K (AB Mix 10 mL / L air), P1 (8 mL / L air), P2 (10 mL / L cow urine), P3 (cow urine) 12 mL / L air), P4 (cow urine 14 mL / L). The data obtained were analyzed using Analysis of Variance ANOVA. The parameters considered were tall plants, number of leaves, wet weight and dry weight. The results showed the facts about the conservation of hydroponic nutrition of organic fertilizers made from cow urine provided were not significantly different and could not increase the growth of pakcoy (Brassica chinensis L.) plants.Keywords: Pakcoy, Hydroponics, Cow Urine.
