ABSTRAK Potensi pemanasan global disebabkan oleh beberapa aktivitas manusia, salah satunya pengelolaan sampah. Pengelolaan sampah menghasilkan potensi pemanasan global dari proses pengangkutan dan pengolahan yang berhubungan dengan material, kebutuhan energi dan hasil sampling dari keseluruhan prosesnya. Dampak lingkungan dari pengelolaan sampah sering kali tidak dipertimbangkan. Hal tersebut akan berpengaruh pada penerapan regulasi untuk mengelola sampah secara holistik. Penelitian ini bertujuan untuk mengetahui skenario terbaik dengan potensi pemanasan global yang paling rendah dari pengelolaan sampah rumah tangga dengan mempertimbangkan dampak lingkungan dari proses pengelolaanya terutama yang berhubungan dengan potensi pemanasan global. Penelitian ini menggunakan pendekatan penilaian daur hidup atau LCA menurut ISO 14040:2006 dengan unit fungsional 1 ton sampah rumah tangga. Kategori dampak dibatasi hanya untuk analisis potensi pemanasan global dari ketiga skenario yang ditentukan berdasarkan tujuan dan definisi. Metode analisis dampak (LCIA) menggunakan Center of Environmental Science Leiden University Impact Assessment (CML-IA) dengan software SimaPro program versi 9.1. Hasil penelitian menunjukan bahwa skenario terbaik dengan potensi pemanasan paling rendah yang dianalisis dengan pendekatan LCA adalah skenario 2 dengan 5,0 × 10-6 kg CO2-eq, sedangkan skenario 0 adalah 1,21 × 10-5 kg CO2-eq dan skenario 1 adalah 6,0001 kg CO2-eq. Maka, pengelolaan sampah rumah tangga terbaik dengan dampak paling kecil adalah pengelolaan dengan skenario 2, meliputi: pemilahan sampah, komposting rumah tangga, penyaluran ke bank sampah, dan pengangkutan residu ke TPA. Kata kunci: Potensi pemanasan global, Pengelolaan sampah domestik, Penilaian daur hidup ABSTRACT Global warming potential is caused by several human activities, waste management is one of them. Municipal waste management releases the global warming potential from transportation and treatment processes related to the material, energy needs, and byproducts. Often, environmental impact from domestic waste management is not considered. Therefore, it will affect the implementation of regulation in handling solid waste holistically. This research aimed to produce the best scenario with the lowest global warming potential for domestic waste management. This research used Life Cycle Assessment (LCA) approach according to ISO 14040:2006 with the functional unit of 1 ton of domestic waste. The impact category was observed and limited on global warming potential (GWP) by analyzing three scenarios based on goals and scope definition. The LCIA method used was the Center of Environmental Science Leiden University Impact Assessment (CML-IA) using SimaPro program version 9.1. The results show, the best scenario with the lowest GWP based on the LCA approach is scenario 2 with 5.60 × 10-6 kg CO2-eq. While, scenario 0 is 1.21 × 10-5 kg CO2-eq and scenario 1 is 6.0001 kg CO2-eq. Therefore, the best scenario with the lowest GWP of domestic waste management is scenario 2, which manages upstream domestic solid waste management: sorting of waste, household composting, distributing to waste bank, and transporting residue to landfill. Keywords: Global warming potential, Domestic waste management, Life Cycle Assessment (LCA)

Pest attacks that result in reduced crop yields require alternative control that is able to prevent damage to agricultural land. Organic pesticides are environmentally friendly pesticides because the materials used are derived from natural ingredients, one of which is liquid smoke, namely liquid smoke made from natural ingredients containing cellulose, hemicellulose, and lignin. This study was to determine the effect of giving liquid smoke of siwalan peel waste as an organic pesticide. Liquid smoke is obtained from the combustion process with a little oxygen at a certain temperature. The content of compounds in liquid smoke was analyzed using GCMS. Pyrolysis results obtained dark brown liquid smoke, clear, has a smoke-like odor (sangit), and has a watery texture which is used as an organic pesticide on spodoptera litura with varying concentrations of 5%, 7%, 9%, 11%, and 13%. The results of the GCMS analysis found 18 components of the liquid smoke of siwalan rind waste, among the compounds that function as organic pesticides are phenol, furfuran, acetone, and palimitic acid. The results of the analysis of the mortality of spodoptera litura sequentially showed the average value of mortality in 2 repetitions, namely 5%, 10%, 15%, 20%, and 35%. The greater the concentration of liquid smoke, the higher the mortality value. However, it is less effective to kill spodoptera litura quickly, even mortality at a maximum concentration of only 35% or has not reached the death rate of 50% of test animals.

Indoor air pollution is dangerous for human health because almost 90% of human activity occurs indoors. An important factor when assessing indoor air quality is the concentration of carbon dioxide (CO2). Even at very low concentrations, it can have a marked effect on the health of those in it. The purpose of this study was to review the ability of moss used as a living wall to absorb CO2 and study its potential application in improving indoor air quality. In addition, this research will also identify challenges that may be faced in implementing living moss walls. This study used the true experimental method with a pretest and posttest control group observation design. The study was conducted by comparing CO2 levels from 2 white cigarette smoke with and without living moss wall in a prototype room made of glass with dimensions of 40 cm x 40 cm and 55 cm high.The research results show that the use of living moss wall as a solution to overcome indoor air pollution, especially CO2, cannot be separated from several obstacles that must be faced in its implementation. Living moss wall has a relatively low CO2 reduction efficiency value by using blumei’s moss (Macromitrium blumei). The use of a living moss wall must also pay attention to the suitability of the environment where it is installed so that the living moss wall can function properly.Keywords: Living moss wall, carbon dioxide (CO2), indoor air pollution ABSTRAK Pencemaran udara dalam ruangan berbahaya bagi kesehatan manusia karena hampir 90% aktivitas manusia terjadi di dalam ruangan.
