Abstract

Pengelolaan sampah perkotaan di Indonesia masih menghadapi banyak kendala terutama dalam hal keberadaan Tempat Pembuangan Akhir (TPA) atau landfill. Hanya 60-70% sampah yang dapat terangkut dan dibuang ke TPA, sementara sisanya tersebar diberbagai tempat. Padahal sampah yang dibuang ke TPA menimbulkan pencemaran air lindi dan gas rumah kaca. Selain itu juga sampah merupakan pemborosan sumber daya alam yang tak terbarukan. Diperlukan manajemen yang bersifat holistik, mulai dari hulu hingga ke hilir pengelolaan sampah. Konsep Zero Waste menawarkan pengelolaan sampah, dimulai dari peniadaan sampah, daur ulang, reduksi dan pemulihan barang bekas. Sejumlah kota di dunia seperti Canberra, Adelaide (Australia), Stokholm (Swedia), Nova-Scotia (Kanada) dan San Fransisco (Amerika Serikat) telah menetapkan target Zero Waste.  Indonesia sendiri masih menerapkan manajemen pengelolaan sampah yang menekankan pada pembuangan di TPA. Studi literatur ini bertujuan untuk mengetahui apakah Indonesia dapat menerapkan konsep Zero Waste di masa depan

Abstract

In order to achieve the national target of decarbonization by 2030, Palm oil mills (POM) can contribute to reducing CO2 emissions generated from their production activities. The CO2 emitted from POM is currently discharged into the environment without further treatment. As a result, the amount of CO2 in the atmosphere will rise, increasing global warming. This study proposes an approach of utilizing CO2 as a density agent in separation fluid formulation. The formulated fluid is then used to separate palm shells and kernels in the claybath. The solubility of CO2 in water occurs physically and is dependent on temperature and partial CO2 gas in the air. Monoethanolamine (MEA) was used as an absorbent to ensure the full interaction of CO2 with water. The chemisorption method is selected to dissolution CO2 into aqueous MEA. The mass ratios of MEA were varied by 10, 20, 30, 40, 50 % w/w. The achieved appropriate densities of formulated fluid were 1,11, 1,14, dan 1,17 g/cm3 at mass ratios of MEA:H2O is 30, 40, dan 50% w/w, respectively. All achieved densities fall between palm shells and kernels densities. Furthermore, the formulated fluid can be used as separation fluid in claybath for separating palm shells and kernels. In addition to the proposed idea of utilizing CO2  and, at the same time, reducing CO2 emission from POM.

Abstract

There are many methods of waste treatment, but not all methods of waste management can be applied. For example incineration and biogasification require relatively high investment and operational costs, making it less feasiblein developing countries. One of the feasible methods to consider is the utilization of waste as a renewable fuel or commonly referred to as waste derived fuel (RDF). This study aims to determine the composition of municipal waste for RDF production so as to generate optimum fuel value to substitute fossil fuels. The waste used as a sample for RDF production is obtained from TPA Kampung Jawa. Sampling is done twice daily for five consecutive days. Samples are first grouped by type plastic, organic and paper. Subsequently the sample was crushed andsieved into several sizes 2, 6 and 10 mesh. After the preparation process, the samples were analyzed for water content, ash content, elemental content C, H, N, S, O, and fuel value. optimization is done by using Design Expert application. The results of this study showed that organic, plastic and paper waste water content were 34.99 - 54,60 %, 0.42 - 0.64 %, and 2.05 - 3,72 %, respectively. The optimization result with the expert design obtained the optimum composition of RDF is plastic; 29.32 %, paper; 38.99 % and organic; 31.69 %, with the calorificvalue per sample size being 2 mesh 4939,23 kcal/gram), 6 mesh 4939,35 kcal/gram 10 mesh 4939,41 kcal/gram.
