Abstract

Jambi City's Food Land decreased during the period 2001 - 2020 by 24.77 percent per year, while the population growth rate of Jambi City increased by 1.85 percent per year. This condition causes food production to decrease but food demand increases along with increasing population growth. Therefore, it is necessary to carry out an urban farming strategy, namely food land intensification, food diversification, utilization of Sustainable Food House Areas (KRPL), determination of Sustainable Food Agricultural Land (LP2B), expansion of food land or agriculture-based Green Open Space (RTH) and suppression of the rate of growth. population growth. The purpose of the study was to analyze the development of food land in Jambi City, to analyze the development of the Foodstuffs Balance of Jambi City, to analyze the growth of the Food Expectation Pattern of Jambi City, to determine the relationship between food land and the Foodstuff Balance of Jambi City and to determine the relationship between the Foodstuff Balance and the Expected Food Pattern of Jambi City. The research method is descriptive quantitative and simple linear regression. The secondary data used is the Decision Number II (ATAP II) recorded at the Jambi City BPS and Jambi City DPKP. Analysis using the Statistical Package for the Social Science (SPSS) program. The results showed that Jambi City's food area was reduced by -19018 ha or 96.01 percent with a linear trend of -698.95 ha/year. The development of the Balance of Foodstuffs for main food is an average of 131.9 kg/cap/year, Energy Adequacy Number 11.78 kcal/cap/day, Protein Adequacy Rate is 1.0944 gr/cap/day, Fat Adequacy Rate is 0 .7585 g/cap/day, and the score of the Hope Food Pattern in Jambi City was 82.3. The correlation between food land and food ingredients balance is 0.416 kg/cap/year for every 1 ha, the correlation between food items balance and expected food pattern for AKE is 0.125 per 1 kcal/cap/day, PPA is scored 0.361 for 1 g/cap/day. day and AKL got a score of 0.365 every 1 g/cap/day.

Abstract

Landfills (TPA) are a significant source of methane emissions into the atmosphere. In Indonesia, the estimation of methane gas production from a landfill has not been widely carried out. The purpose of this research is to measure production and measure the concentration of methane gas emitted into the atmosphere, assess methane gas emissions as an energy source, and analyze the potential costs and benefits of electrical energy that can be generated from methane gas emissions at the Talang Gulo TPA. The emission data obtained can be used as material for analysis to create a project for developing a gas processing system from a landfill. This estimation approach is carried out in three ways, namely prediction with LandGEM-v302 software, field measurements with methane flux and utilization of methane gas production as an energy source. The LandGEM-v302 simulation results obtained a total landfill gas of 29.96 Gg/year consisting of CH4 of 8.002 Gg/year, CO2 of 21.96 Gg/year and NMOC (non-methane organic compounds) of 0.344 Gg/year. The results of field measurements on the surface of the closed chamber TPA obtained CH4 emissions from TPA Talang Gulo of 4.75 Mg/year. The different characteristics of the landfill surface greatly affect the gas emissions released into the atmosphere. Moisture conditions or water content in the waste also affect the methane emission rate. The electricity potential from methane gas is 15.718 MW so that the cost benefit analysis shows an NPV of Rp. 6,028,622,852.18, B/C Ratio of 0.00196 and IRR of 2.445%.
