Abstract

The research was conducted to evaluate the effect of mulch and mixed cropping grass – legume atsaline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in thisresearch was classified into strongly saline soil with low soil fertility. The research was arrranged inrandomized complete block design with 3 blocks. The treatments were : M1 = guinea grassmonoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grassmonoculture, 6 ton/ha mulch, M4 = mixed cropping grass with Sesbania grandiflora, without mulch;M5 = mixed cropping grass with Sesbania grandiflora, 3 ton/ha mulch; M6 = mixed cropping grass withSesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed byDuncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegumewith 6 ton/ha of mulch. The effect of mulch at saline soil significantly increased plant growth,forage yield and nutritional quality of guinea grass. Application of 3 ton/ha mulch increased plantgrowth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritionalquality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Abstract

The objective of this study was to evaluate the effectiveness of phosphate rocks (PRs) fertilizercompared to chemical P fertilizer for the best crop production and macronutrients of alfalfa. Acompletely randomized design under 3x3 factorial patterns was used in this research. The first factorwas different sources of P fertilizer: Guizhou Phosphate Rock (GPR), Jingxiang Phosphate Rock (JPR),and Single Super Phosphate (SSP). The second factor was level of P fertilizer: 75, 100, and 125 mgP2O5/kg soil. A control treatment (without addition of P fertilizer, CK) was added as a comparison withthe treatments. The results showed that JPR was the best for alfalfa production, whereas GPR and SSPwere better for nutrient content in the alfalfa tissue than JPR. On the whole, phosphate rocks had similareffect on alfalfa growth compared to SSP at the experimental conditions.

Abstract

Among several cruise lines, Madura Strait is one of the densest cruise shipping course that also has a high risk of accidents. According to marine accident report data, in the range of 1995 - 2010 is about 311 marine accidents happened. Accidents due to collision reached 48.5% of total accidents that occur so the impact of collision analysis is important to do. From the source of Pelindo III stated, in period of the 2008-2013, there are 20,582 ship / year passing through Madura strait channel.Traffic based models is an accident frequency calculation approach that tailored to technical standards, environmental conditions, and the density of aquatic traffic in an area. Through this method can be estimated the frequency of collision accidents, aggregates and also the intersection of a specific area. Based on the value of Pc on the Madura Strait (APBS) with the value of Nm, where Nm = 3, there are some values obtained, for Head On obtained Pa = 1.819 E-06, for Crossing obtained Pa = 1.304 E-06 and for Overtaking obtained Pa = 6.299 E-06. Accidents due to Overtaking is the highest accident type of calculation, this is because Pc value is the greatest in APBS path in Inner Channel.
