Abstract

Daun pisang sering menjadi limbah dari aktivitas manusia. Meskipun demikian, daun pisang memiliki kandungan karbon yang membuatnya berpotensi sebagai bahan bakar. Namun, kendalanya adalah kadar air yang tinggi dalam daun pisang, yang dapat menghambat efektivitasnya sebagai sumber energi. Untuk mengatasi hal ini, diperkenalkan proses Biodrying. Melalui Biodrying, mikroorganisme digunakan untuk mengurangi kadar air dalam limbah organik, seperti daun pisang, sehingga meningkatkan potensinya sebagai bahan bakar. Penelitian ini dilakukan untuk menganalisa seberapa efektif Biodrying dalam meningkatkan nilai kalor daun pisang. Selama proses Biodrying, terjadi pengurangan massa dan kadar air pada daun pisang. Sejak hari pertama, suhu dalam tumpukan sampah daun pisang meningkat, menandakan aktivitas mikroorganisme, dengan pH yang tetap normal. Hasil akhir menunjukkan bahwa kadar air daun pisang berkurang sekitar 45,3% hingga 50,49%, dan nilai kalor yang dihasilkan mencapai standar pellet biomassa, yaitu antara 19.9 MJ/kg hingga 21.4 MJ/kg. Ini menunjukkan bahwa daun pisang, setelah melalui proses Biodrying, memiliki potensi besar untuk dimanfaatkan sebagai sumber energi yang efisien.

Abstract

This study concerns the design of a waste management system using the Material Flow Analysis (MFA) method in the city of Tasikmalaya. TPA Ciangir is the only landfill in Tasikmalaya, and its storage capacity has reached its maximum, necessitating improvements in waste management. The aim of this design is to determine an appropriate waste management system that can be implemented in Tasikmalaya. Based on observations and interviews, waste collection at TPA Ciangir in Tasikmalaya is conducted in small amounts, leading to a significant amount of household waste not being collected daily, resulting in waste accumulation and minimal transport to waste processing facilities. According to Permen PU Number 3 of 2013 and SNI 19-2454-2002, waste collection from the source should be conducted at least once every two days. Therefore, an evaluation and redesign of the waste management system based on technical aspects are needed. The best system selection will be carried out using the Analytical Hierarchy Process (AHP) method, which will then be recommended for application at TPA Ciangir in Tasikmalaya. Based on the calculations using the AHP method, scenario 3 scored the highest, at 1.676, using composting processes, RDF, and TPST-3R. From the design results, a total waste reduction of 81% was achieved, aligning with the government's target of a 70% waste reduction by 2020.

Abstract

West Jakarta has the farthest distance for the waste transportation process compared to other municipalities in DKI Jakarta. The number of population and garbage which always increases every year can make the West Jakarta area experience new problems with the waste transportation system. In existing conditions, there are 68 out of 195 trucks in 174 temporary trash shelter that do not have a volume of waste that can immediately fill containers in 1 day of garbage collection. The trucks have to wait for further collection until the truck containers are filled. In addition, there are 31 trucks which transports waste in temporary waste shelter with a generated amount that exceeds the capacity of the truck. This can cause the waste to settle at the temporary trash shelter or the truck will carry more waste than it’s capacity. Therefore, the goal to be achieved in this design is to optimizing the waste transportation system in West Jakarta with SCS from a technical and economic point of view. After evaluating the existing conditions and analyzing the alternative choices made, it was found that the system can be optimized using the Hauled Container System (HCS) and the Stationary Container System (SCS) with 1 and 2 transportation rit / day. The number of trucks could be reduced from 195 to 73, with 70 trucks doing 2 rit / day and 3 trucks doing 1 rit / day. The number of drivers can be reduced from 195 to 143 drivers, with each driver only working for 1 rit. There was a decrease in the cost of diesel fuel / month from Rp873,158,589 to Rp853,612,500 and could reduce the driver's wages from Rp711,366,825 to Rp521,669,005 each month. The total transportation cost for diesel fuel and employee wages in a month is Rp1,375,281,505 or Rp209,243,909 cheaper than the existing conditions.

Abstract

The mismanagement of solid waste transportation to landfills contributes to various environmental issues, including increased greenhouse gas (GHG) emissions, propagation of disease vectors, aesthetic degradation, and interference with market activities. Addressing these challenges necessitates efficient waste processing at the source to mitigate waste accumulation at temporary dump sites and reduce GHG emissions. This study proposes the design of an integrated anaerobic digester at Pasar Kemiri Muka, specifically selected for its ability to convert organic waste into renewable energy. The anaerobic process is advantageous as it produces methane with a high calorific value, suitable for generating electricity. The generated electricity is then utilized to improve street lighting in the market area, which currently suffers from insufficient and poor-quality lighting. The proposed system is designed to power 14 LED street lights, requiring only 10m² for installation and incurring an operational cost of IDR 525,000. This approach not only provides a sustainable energy source but also enhances local infrastructure, contributing to a cleaner and more efficient market environment.
