Abstract

Wijayakusuma ornamental plant (Epiphyllum oxypetalum (DC.) Haw.) is a plant that is easily propagated by cuttings. To overcome this problem, it is necessary to pay attention to the planting media used. This study aims to determine the effectiveness of providing planting media based on biotechnology agents on the growth of Wijayakusuma ornamental plants. This study is a quasi-experimental quantitative study using a Randomized Block Design, this study used six treatments with four replications. Follow-up test using Duncan's Post-Hoc Test at a level of 5% using SPSS version 26 program. The results of the analysis of various studies stated that planting media based on biotechnological agents with a mixture of burnt husks, cocopeat, raw husks, andam, livestock manure and liquid fertilizer obtained results < 0.05 which means that it has a significant effect on the parameters measured, such as the number of leaves, stem height, and plant root length. These results indicate that the effectiveness of using growing media containing potassium, calcium, phosphorus, through the fermentation process, contains biotechnological agents such as rhizobium, mycorrhizae, and phytohormones that affect plant growth. The most optimal composition of planting media based on biotechnology agents for plants based on Duncan's Post-Hoc test results is T2 treatment with a composition of growing media based on biotechnology agents + roasted husk growing media. Then there is no relationship between climatic factors with the growth of ornamental plants Wijayakusuma. Wijayakusuma plants grow well in places that are not exposed to direct sunlight, normal environmental temperature and humidity, moist soil that is neither too wet nor too dry, and optimal soil pH.

Abstract

Livestock is a sector that has a huge opportunity to be developed as a business in the future. According to BPS data in 2014 there were 4.104 heads of cattle and in 2016 decreased with a total of slaughtering as many as 3,461 heads of cattle. From this data it can be seen that the number of cattle slaughtering in Sumbawa Regency can be said to be quite low for the needs of beef in Sumbawa Regency. In Sumbawa especially, the problem of beef lies in relatively expensive price. This study aims to determine the supply chain of beef from slaughterhouse to end consumers by using data collection methods, and determining respondents (snowball sampling technique and purposive sampling technique). The result of this study is the marketing efficiency of beef shows that the efficiency of marketing of 0 (zero) level of beef seller-consumer is 0% smaller compared to the level marketing efficiency of level 1 (one) of meat retailers-consumers of 0.87 %. Value added at the level of beef seller (butcher) shows that the conversion factor value is 1.30 where the conversion factor is obtained by dividing the output value with the input value for every 1 medium-sized cattle.
