Abstract

Gasifikasi menggunakan limbah padat kota (MSW) berdampak pada peningkatan kualitas lingkungan dan peningkatan pasokan listrik untuk daerah-daerah yang sulit dijangkau, khususnya di Indonesia. Namun proses gasifikasi membutuhkan proses pengujian kualitas terlebih dahulu agar dapat menghasilkan produk syngas dan kelistrikan yang maksimal. Maka dalam penelitian ini dilakukan proses pengujian pengaruh variasi Air Fuel Ratio (AFR) terhadap kualitas proses gasifikasi (Cold Gas Efficiency (CGE), Carbon Conversion Efficiency (CCE), dan specific fuel consumption (sfc) atau konversi konsumsi spesifik). Penelitian dilakukan dengan melakukan proses gasifikasi dengan tipe downdraft pada nilai AFR 0,5; 0,51; 0,53; 0,54; 0,55. Hasil penelitian ini menunjukkan adanya peningkatan nilai syngas seiring dengan peningkatan nilai AFR. Sedangkan nilai CGE meningkat seiring dengan meningkatnya AFR proses gasifikasi MSW. Peningkatan terjadi dari 9 menjadi 13%, meskipun hasil ini masih sangat rendah. Di sisi lain, CCE juga mengalami peningkatan dengan meningkatnya AFR gasifikasi MSW. Peningkatan nilai terlihat dari 33-43%. Hasil ini juga masih tergolong kecil, artinya efisiensi konversi karbon pada proses ini sangat rendah. Pada akhirnya, dapat dilihat bahwa nilai scf menurun dengan meningkatnya AFR. Penurunan yang didapat adalah dari 5,3 menjadi 2.

Abstract

Energy needs in Indonesia always increase along with population growth and industrial growth. On the other hand, the abundant availability of biomass waste, especially teak sawdust and corn cobs, encouraged researchers to find the right technique for converting biomass waste to make the waste an alternative energy source. Hydrothermal Treatment is one of the techniques for thermal biomass conversion that can convert biomass into coal-like material called hydrochar. The biomass waste is in a heterogeneous or mixed state.The purpose of this study is to obtain the optimum composition of the biomass mixture to make solid fuels using the hydrothermal treatment method and to do a regression analysis to estimate heating value based on proximate analysis. The biomass waste used in this study was teak sawdust and corn cobs powder. The results from this study are the highest yield of hydrochar in the hydrothermal treatment process of teak sawdust which is equal to 68.1% and the highest calor value in the hydrothermal treatment of biomass with the same composition which is equal to 5402 cal / gram. An equation to predict the value calor hydrochar is HHV = 0.837 (% AC) +0.152 (% VM) +0.389 (% FC) -0.022 (% WC) with an absolute error of 4.11% and a relative error of 0.28 %.

Abstract

The agriculture and livestock sector is the biggest contributor to environmental damage. Where from the total national sources of greenhouse gases, the agricultural sector accounted for 13.6%. From this data, there needs to be an appropriate design to deal with this problem. One way is to apply the concept of industrial ecology as the best solution to deal with this problem. So that in this study quantitative calculations were carried out to determine the potential application of the concept of industrial ecology in the agriculture and animal husbandry sector in the Tojang Maju 3 Farmer Group located in Masbagik District, East Lombok Regency, West Nusa Tenggara Province. The study was conducted with a quantitative calculation of waste generated by the livestock sector as well as farmer group questions, which then carried out the design process of the industrial ecological model. The results obtained the use of liquid organic fertilizer (POC) in the agricultural sector as much as 280.5 for rice, 37.4 for chilli farming, and 37.4 liters for cabbage farming and the rest as sources of economics. Whereas straw produced by rice farming (57,000 kg) is used as silage in the livestock sector with a demand of 4,957.2 kg. Rice straw is also used in the chilli agriculture sector as mulch with a requirement of 1,140 kg and the rest (50,903 kg) is used as raw material for the production of synthetic gas for energy sources of farmer groups. While the rest of the chilli and cabbage agricultural products are used as raw material for biogas with a mass of around 70,300 kg which is directly utilized by the groups. For cow as much as 5,355 kg is fed to the biogas digester as biogas for the consumption of farmer groups, with a gas potential of 535.5 m3.
