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.

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.

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.

Cattle Farm should not only be focusing on increasing productivity and maximizing profit but also on the environmental issue that happens around it. Recycling the waste and turning it into fertilizer is an excellent method of waste management. Effective and efficient organic waste management also provides great benefits for humans. One method that can be used is by using the vermicomposting method using Lumbricus rubellus earthworm inside a bamboo reactor. In this research there are two bamboo reactors are used, Reactor A contains a mixture of cow dung and rice straw, and Reactor B containing cow manure only. Physical parameters that were observed are moisture content, pH, temperature, color, and odor. The data were taken around weeks 0, 2, 4, and 6. It shows that the composts have water content values over 50%, pH values between 6-9, temperatures of <30 ° C, blackish in color, and an odor that resembles the smell of soil. From the four parameters examined, only the water content did not fulfill the SNI 19-7030-2004 requirement about the standard of compost quality, however water content can be controlled by drying.

Solid waste management is a very important part to be done including in the religious tourism park because cleanliness reflect purity. This study aims to plan solid waste management system in the religious tourism park in Indonesia, especially in Gunungpring park tomb. Solid waste management planning is determined by sampling and measuring for eight consecutive days. The solid waste management system is planned to cover storage, collection and transportation as well as processing solid waste facilities named TPS 3 R and transportation of the residue. Based on the sampling result and the measurement of solid waste generation, it is known that the average amount of solid waste is about 0.14 kg or 0.3 liter per person per day. While the composition consists of 49.84%, 29.53% and 20.63% respectively for recyclable, compostable and disposable waste. Storage at Gunungpring Religious Tourism Park need to be installed in five locations with three types of containers, while collection used motorcycle cart with capacity of 84 liters. In order to obtain optimum results, a planning and designing the TPS 3 R installation is necessary and finally the disposable waste transportation was design to obtain the method and intensity of disposal and size of dump truck.

Microplastics are emerging contaminants that degrade from textile plastic products, petroleum, and cosmetic equipment with sizes less than 5 mm. There are more than 70,000 settlements located along the Ciliwung River in DKI Jakarta that use the river water as a source of clean water. The most common type of waste found in the Ciliwung River to date is plastic waste, which can cause flooding and other disasters. The Ciliwung River can currently be found with microplastic pollution which has an impact on exposure to living things in the river, such as in case studies in the Ciliwung River estuary area. The problem is the exposure to 75% of blue panchax fish (Aplocheilus sp.) as many as 1.97 particles per fish with sizes of 300 to 500 μm. This research will focus on analyzing the dynamics of microplastic quantity in water and sediment of the Ciliwung River along with the correlation between field parameters and population density around the banks of the Ciliwung River. When viewed from the seven points that represent the Ciliwung River downstream to upstream in DKI Jakarta Province, the number of microplastics is in the range of 320-741 particles/L. For the dominating form, it can be analyzed that the majority of microplastic forms are fragments (97%), followed by fibers (2.9%) and pellets (0.1%). While in the sediment, the number of microplastics in the Ciliwung River sediment is in the range of 6560-10630 particles/kg. The population density factor has the highest correlation to the number of microplastics with a value of r = 0.702. This is associated between population density and high microplastic emission loads.

One of the problems that are faced by the Universitas Islam Indonesia (UII) is the amount of solid waste generated each year, add the increasing number of the student each year, then the problem becomes much worse and difficult to handle. Regarding it, the awareness of each student about solid waste management is needed. The 2 main purpose of this study is first to determine the composition and the generation of solid waste using the samples taken from 10 temporary solid waste dumps (FPSB, D3 Economics, FMIPA, FTI, FIAI, FTSP, FK, Central Library, Kahar Muzakir, GKU, and Rectorate) and the second is to identify student’s perceptions and behavior about individual solid waste management. The research was conducted using qualitative and quantitative descriptive approaches. The results show that the average amount of solid waste generated is 0.017 kg/person/day this is in line with the solid waste management record that shows that on daily basis each person produces approximately 0.010 - 0.020 kg. While the study about the students’ perceptions and behavior towards solid waste management shows that while most of the students are aware of it, the implementation is still lacking.
