Abstract

Universitas Negeri Malang (UM) merupakan salah satu perguruan tinggi yang ada di Kota Malang. Memiliki jumlah mahasiswa terbanyak kedua setelah Universitas Brawijaya (UB). Universitas Negeri Malang memiliki luas wilayah 463.992 m2, dengan empat  gerbang yang menjadi akses utama keluar masuk kendaraan bermotor. Dengan makin banyaknya perguruan tinggi di Indonesia yang menerapkan konsep Green Campus (Kampus Hijau), maka UM mulai berbenah guna mengaplikasikan konsep tersebut. Langkah awal untuk mewujudkan Green Campus yaitu penyiapan lokasi parkir sehingga tidak ada kendaraan bermotor yang parkir di sepanjang jalan dalam kampus UM. Langkah berikutnya yaitu disiapkannya sejumlah sepeda yang bebas digunakan warga UM sebagai sarana transportasi selama berada dalam wilayah kampus UM. Tujuan utama penelitian ini adalah untuk mengetahui jumlah emisi CO2, CH4, dan N2O yang dihasilkan dari kendaraan bermotor yang masuk ke dalam wilayah UM. Jenis kendaaan bermotor dibagi menjadi motor (MC), kendaraan ringan (LV), dan kendaraan berat (HV). Proses analisis jumlah emisi berpedoman pada Intergovermental Panel on Climate Change (IPCC), dimana menggunakan pendekatan konsumsi bahan bakar. Selain itu, penelitian ini menunjukkan pola pergerakan kendaraan bermotor yang ditampilkan dalam Peta Asal Tujuan (desire line map) dari masing-masing gerbang masuk ke tiap area parkir. Hasil penelitian menunjukkan jumlah emisi paling besar dihasilkan pada hari Rabu (weekday) dengan 159,90 Kg CO2, 0,0116 Kg CH4, dan 0,0014 Kg N2O. Sedangkan untuk jumlah emisi pada hari Sabtu (weekend) sebesar 93,71 Kg CO2, 0,0068 Kg CH4, dan 0,0008 Kg N2O.

Abstract

The research on the processing of organic municipal waste conversion has been done by using pyrolysis method. The research aims to gain an alternatif fuels and to minimize the landfill space. In the pyrolysis process, it was investigated the char formation as solid fuel as well as its heating value. The char formation was determined by the change of mass and volume of waste for minimizing landfill area.The waste compositions were obtained by surveying the 10 families during 10 days and then it was made the waste spesimens as the pyrolysis feedstocks. The pyrolysis processes were operated in range temperature 200oC to 400oC. Then, the char formations as pyrolysis products were tested by using bomb calorimeter to qualify the heating value of the products. The results showed that the waste was able to be a solid fuel due to the quality of its heating value. The increasing of the heating value could reach 150% from unpyrolyzed waste to pyrolyzed one. In addition, the pyrolysis method was able to significantly minimize the volume of waste, so that it has a potential way to overcome the need of a large landfil area in which it could reduce up to 50% in mass and 85% in volume. In waste pyrolysis method, it was only needed 2 hours operating process and low-temperature process (only up to 300oC). It did not require require a high-operating temperature, therefore, the handling of municipal organic waste to save area landfill and produce alternative fuel could be done in short time and did not require great energy.Keywords: waste, conversion energy, alternatif fuels, pyrolysis

Abstract

Supit Urang Landfill is located in Mulyorejo, District of Sukun, City of Malang. There are scavenging activity by 217 scavengers in Supit Urang Landfill but there has been no related with management’s activity of the scavengers. Without the scavenger’s management there are many violations that disturb the operational tools that interfere with landfill work and also endangering the scavengers. Recommendations of the involvement of scavengers in Supit Urang Landfill were formulated by evaluation of operating system, identification the benefit of scavengers activity and empowerment management‘s recommendation. The evaluation of operating system in Supit Urang Landfill by scoring analysis showed that the operational system is controlled landfill so scavenging activities is a legal activity. Identification contribution of scavenging activity by economic estimation based on cost and benefit showed that the scavengers in supit Urang reduced waste and operational cost by 1.9% and 1.26%. This activity also gave scavengers benefit up to 5.48 much bigger than scavenging cost. Empowerment management were formulated by location for scavengers and recommendation for empowerment’s factors that influence with scavengers in Supit Urang Landfill. Map’s overlay, counting of rits and operational times were used to choose location for scavengers. Locations for scavengers are in limited cultivation zone with a distance of 800 m from the active cell with 7.57 hour of waste travel time per day. Factors that influence the empowerment of scavengers at Supit Urang Landfill are institutional, home range and activity. Keywords: Scavengers, Controlled Landfill , Benefit Cost Ratio

Abstract

Tegalweru village is dominated by farmers, with the total number of cows are 1.080. But, the results of the primary survey show that only 27 cows ware utilized as biogas to produce an alternative energy source. In order to improve the utilization of manure waste into biogas there are 3 analysis used in this research, there are emergy analysis, IPA analysis and regression analysis. Emergy analysis was used to determine the best scenario to be applied in Tegalweru Village. Furthermore, IPA analysis was used to evaluate the performance of existing biogas and also regression analysis to find out the factors that influence the interest of farmers to use biogas. The results showed that the best scenario to be applied is the utilization of manure from 1,080 cows. Evaluation of the performance of biogas showed that the variables which have a high level of importance but low satisfaction levels are the availability of land for biogas, energy for cooking and energy for lighting. While some variables that significantly influence the farmers to have biogas installation are the availability of land, level of education and number of cows which they have. The output of the analysis are recommendations based on the analysis which had been done before. The recommendations for farmers as users of biogas derived from IPA analysis results and recommendations for non-biogas farmers derived from the results of the regression analysis.Keywords: Livestock Manure Waste, Emergy Analysis, Biogas.

Abstract

Pudak Wetan is the name of a village in Ponorogo which has a Livestock Center (RTRW Ponorogo 2010-2013). So that Pudak Wetan has an alternative energy resource for cooking, in the form of cow manure potency with the ownership of ±2-4 cows/breeder. But in fact, there’s just 8,8% of 329 breeders who can manage their waste to make it into biogas with the biodigester. Operational requirement of biodigester sized 6m Jurnal Tata Kota dan Daerah Volume 5, Nomor 2, Desember 2013 109 3 is every farmer has at least 2 adult cows. Gas production can be used for 7 hours of cooking time, but every farmer to use gas only for 3-4 hours. There are only 5 of the 29 breeders who utilize biogas communally because of family connections. Another problem is very hard to realize the centrality into the village scale because of the settlement and the topography. Therefore the primary aim of this research is to identify the best alternative to distribute the cow manure potency and then the best alternative is used as a reference division of the breeders group based on spatial and statistical characteristics.This paper use some methods for analising, there are multicriteria analysis, spatial cluster analysis, and statistic cluster analysis. There are four variabels in this research are location, economic, social, and technical. The result of this research shows that the best alternative of the biodigester’s type is the medium scale for 2-5 breeders with 10-25 cows. In this system, there are 25 groups for breeders which is the maximum size is 22m 3 for 5 breeders and the minimum size is 6mKeywords : Biogas, Cow Manure , Biodigester , Alternative Distribution of Biogas
