The rotational planting was applied as the result of decreasing the number of pineapple production. The decreased pineapple production is influenced by soil fertility measured from the chemical, physical, and biological aspects. This research was conducted to comprehend the potential of rotational planting. This research was conducted by taking samples from three different locations: PC pineapple (the first plant), RC Pineapple (Ratoon Plant), and bananas after harvest. Samples were taken at a depth of 0-20 cm and 20-40 cm. The research was conducted from November 2015 until February 2016 at Central Lampung. This research found that rotating the planting between the pineapple and the banana can improve soil fertility. After harvest, bananas’ location has soil pH, total nitrogen, C-organic, phosphorus available, and potassium available is higher if compared to PC pineapple and RC Pineapple location. This was based on the fact that the soil of the harvestable banana (4.74) has better pH compared to the two locations, PC pineapple (4.54) and RC pineapple (4.09). This resulted from a larger amount of dolomite given to the harvestable banana’s soil than those from the PCs and the RC’s. Its pH can also influence its OH- and other nutrients within the soil. From the explanation above, it can be concluded that the soil of harvestable banana (ex-banana) has a better quality to increase the production of pineapples.
The development of livestock should be focusing on increasing productivity and maximizing profit and the environmental issue that happens around it. The produced waste can be managed by minimalizing the waste generated by turning it into something valuable or reutilizing it. One way to do it is by utilizing the waste as organic fertilizer (vermicompost). The vermicomposting process resulted in two products that are useful for agriculture; there are earthworm and vermicompost itself. Using the generated waste as growth media for the worm will result in an increased worm population, and the waste will be turned into vermicompost. The earthworm species that will be used in this study is Pheretima sp. This study purpose is to reduce the contamination by the waste generated by livestock, and other purposes are to find out whether the nutrient content in the waste is up to standard and the roles of the earthworm used. The samples were collected on days 30, 45, and 60. The result shows that the only nutrient that can meet the standard is potassium (> 0.2%), while carbon is slightly below standard and nitrogen and phosphor content are way below the standard. From the resulted nutrient content, it can be concluded that the role of Pheretima sp in the vermicomposting process was not optimal resulted in compost that below the Indonesian National Standard for compost.
Faculty of Civil Engineering and Planning (FCEP) Islamic University of Indonesia (UII) after doing zero waste program which has been going on September 2016. Zero waste concept are needed to measure how far the ability virgin material substitution to balance with the system of zero waste. The aims of this research is to calculate zero waste index (ZWI) value, to know the impact of zero waste index, and to give the solution for zero waste program. The location was doing in FCEP UII Campus. The method of sampling was using for this research is refers to SNI 19-3964-1994 about to calculate waste generation of residential. The result shows value of zero waste index at FCEP UII are 0,26. FCEP UII reuse 134,19 kg waste of total 516,37 kg waste that has been produced. The waste that has been reuse is organic waste 87,93 kg, plastic waste 21,49 kg, and paper waste 24,77 kg. 80,10% FCEP peoples already know about zero waste program at FCEP UII. 98,90% of FCEP peoples, was agree with waste segregate, and 57,50% FCEP peoples are don’t know that waste from FCEP have been manage. Although as many as 29% of element campus do not understand about the zero waste program but the majority of them support the program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
