The municipal solid waste management system collects waste from the source to the final treatment site called landfill. The Yogyakarta Special Province has several landfills, one of which is Piyungan landfill, which serves three administrative areas, Yogyakarta City, Sleman and Bantul Regency. As a regional landfill, Piyungan has an area of 12.5 ha with 3 working zones, operationalized since 1995, estimated with the operational time 20 years. So that 2015 should landfill have been closed, but due to the degradation of waste until 2018 landfill is still used. Therefore, an evaluation mechanism is needed to show the existing condition in the field. Using the checklist method, using questionnaires and interviews and utilizing other secondary data. This method consists of five parts and has an assessment criteria in each component obtained assessment of facilities and infrastructure facilities of 2.25 (good category), while 1.68 for operational technical aspects (very good category). Overall Piyungan landfill evaluation scored 1.96 (good category). However, efforts are needed to ensure that the various facilities can be used properly so that the implementation and sustainability can work well.
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.
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.
This study investigated scientific research on mapping the strength of maritime focus research BASED on the 2014-2018 Scopus data. The Ministry of Research Technology and (Kemenristekdikti), especially the Directorate General of Research and Development (RISBANG), has a significant role in improving the quality of higher education. One way to improve higher education quality is through mapping the strengths of research. The power of the study that forms the basis of this mapping refers to RPJPN 2005-2025 and RPJMN 2015-2019, which focuses on Maritime Affairs. This study used three steps methodology; (1). Collecting data was collected from secondary Scopus data year 2014-2018 from Kemenristek dikti in scientific publication focus on Maritime affairs, (2) identifying Scopus data based on sub-focus of maritime affairs, (3). Data analysis using frequency distribution (Determine the range of data, determine the classes, and determine the class interval). This study concluded that 91.1 % (154) of 169 universities published journals indexed Scopus on range 1-19 journal publications within five years. UNDIP (Diponegoro University) has the most journal publications of Maritime Affairs focus.
