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.
The processing of markets’ organic wastes in Indonesia, especially in Yogyakarta, is still done conventionally, that most of it, is directly composted at the Landfill or sometimes even directly dumped without going through the composting process. This research was conducted to maximize the processing of the organic waste that was generated by the local market, using continuous flow bin and vermicomposting to make it more economically beneficial to the community and to test the chemical parameters like Carbon / Nitrogen, Phosphor, and Potassium level from the vermicast, which is the after-product of vermicompost process. The research process goes through several stages: the acclimatization stage, the feeding stage or the vermicompost process, and the testing stage. Carbon/Nitrogen ratios, Phosphor, and Potassium values in the final results of the three reactors in the composting process meet the composting criteria according to SNI 19-7030-2004. The Carbon/Nitrogen measured in the three reactors were 10.2%, 16.6%, and 11.54%, respectively. The phosphorus levels (P) available in the three reactors were 0.32%, 0.35%, and 0.33%. Potassium (K) levels available in the three reactors were 0.26%, 0.58%, and 0.67%. The K values in reactors 2 and 3 meet the compost criteria or standards from SNI 19-7030-2004 because it is more than 0.20%, while for reactor 1 it is still below the criteria standard.
Sampah merupakan salah satu faktor yang menjadi permasalahan di lingkungan. Jenis sampah yang biasa ditemui dalam kehidupan sehari-hari adalah sampah anorganik dan organik. Salah satu alternatif penanggulangan sampah yang dapat dilakukan ialah dengan menggunakan cacing sebagai objek pengurai sampah dalam mendegradasi volume sampah biodegradable. Penelitian ini menggunakan metode vermikomposting untuk mereduksi sampah organik. Bahan yang digunakan adalah sampah daun kering. Parameter fisik metode vermikomposting dianalisis dalam penelitian ini yaitu kadar air, pH, suhu, ukuran partikel, warna dan bau pada pengamatan hari ke-28, 42, dan 56 disesuaikan dengan SNI 19-7030-2004. Nilai kadar air <50%, nilai pH antara 6,8-7,49, Temperatur <30 °C, warna kehitaman dan bau kompos menyerupai bau di tanah sesuai dengan SNI 19-7030-2004 tentang standar mutu kompos.
Waste is one of the factors that has been a problem in the environment. The types of garbage commonly encountered in daily life are inorganic and organic garbage. One of several alternatives to reduce organic waste is vermicomposting to reduce the volume of waste biodegradable. This study uses the vermicomposting method to reduce organic waste. The material used is dried leaves waste. Physical parameters of vermicomposting method analyzed in this research included physical parameter subjects: the water content, pH, temperature, color, and smell of compost. Physical parameters were analyzed on the 28, 42, and 56 of vermicomposting compared with SNI 19-7030-2004. Value of the water content is <50%, pH values that are between 6.8-7.49, the temperature is <30°C, of a blackish color and odor compost resembling a scent on the ground following SNI 19-7030-2004 about quality standards of compost results.
