Judul: Perubahan simpanan karbon permukaan di Kampus Darmaga, Institut Pertanian Bogor.
Abstrak: Darmaga Campus of Bogor Agricultural University has been developing rapidly, depleting openspace and causing carbon dioxide emission to the atmosphere. Regarding on this matter, Low Emission Development Strategies (LEDS) need to be considered. The purpose of this study was to estimate the amount of above carbon stock in 1989, 1999, 2009, and 2014 by using satellite imagerier. The above carbon stocks were estimated by allometric equation and field measurement of stand parameter (diameter, height, and number of trees) which collected in August – November 2014. Prediction the above ground carbon stock in 2025 was also conducted by using correlation between Normalized Difference Vegetation Index (NDVI), field measurement as well as Masterplan of Campus IPB consideration. Results showed that the amount of carbon stored reserves highly increased in 1999 – 2009 and decreased in 2009 - 2025.

Judul: Economic Value Analysis of Reducing Carbon Emissions Alternatives on Bogor Agricultural University Campus in Dramaga District
Abstrak: Sejalan dengan meningkatnya jumlah civitas dan aktivitas di dalam Kampus IPB, kualitas udara semakin menurun. Salah satu hal yang dapat mempengaruhi kualitas udara adalah terjadinya pencemaran udara oleh Gas Rumah Kaca (GRK). IPB kemudian mencanangkan inovasi untuk menjadi Green Campus sebagai upaya mengurangi emisi karbon. Penelitian ini bertujuan untuk: (1) mengidentifikasi jejak karbon yang terdapat di dalam Kampus IPB; (2) menganalisis skenario penurunan emisi karbon di dalam Kampus IPB, dan; (3) mengestimasi nilai ekonomi yang dihasilkan terhadap skenario penurunan emisi karbon yang akan dijalankan. Penelitian ini menggunakan metode analisis deskriptif kuantitatif, metode Weighted Sum Model (WSM), metode analisis biaya manfaat, dan metode benefit transfer untuk mengkaji tujuan-tujuan penelitian. Hasil penelitian menunjukkan 21 jenis aktivitas sumber penghasil emisi karbon di Kampus IPB selama tahun 2020 menghasilkan total emisi sebesar 69.210.132.584 kg/CO2e. Terpilih tiga alternatif upaya penurunan emisi karbon, yaitu alternatif “Zonasi parkir dan menggunakan transportasi umum yang disediakan kampus apabila ingin berkeliling” untuk aspek transportasi, alternatif “Membawa alat makan dan tas belanja sendiri” untuk aspek sampah, dan alternatif “Menggunakan energi seperlunya” untuk aspek energi. Nilai ekonomi dari alternatif aspek transportasi, aspek sampah, dan aspek energi secara berurutan adalah sebesar Rp62.509.413.531, -Rp234.548.061 (tahun pertama) dan -Rp189.735.061 (tahun berikutnya), dan Rp4.677.239.959., In line with the increasing number of civitas and activities on the IPB University, the air quality has kept decreasing. One of the things that can affect air quality is the occurrence of air pollution caused by greenhouse gasses. IPB then launched an innovation to become a Green Campus as an effort to reduce carbon emissions. This study aims to: (1) identify the carbon footprint contained in the IPB University; (2) analyze the scenarios of reducing carbon emissions in the IPB University, and; (3) estimate the economic values of the carbon emissions reduction scenarios that will be implemented. This study uses a quantitative descriptive analysis method, the Weighted Sum Model (WSM) method, the Cost Benefit Analysis (CBA) method, and benefit transfer method to examine research objectives. The results showed that 21 types of carbon emissions source activities on the IPB University during 2020 produced a total emissions of 69.210.132.584 kg/CO2e. Three alternatives for reducing carbon emissions were chosen are the alternative “Parking zonation and use public transportation provided by the campus if you want to stroll around the campus” for the transportation aspect, the alternative “Bringing your own eating utensils and shopping bags” for the waste aspect, and the alternative “Using energy as necessary” for the energy aspect. The economic values of the alternatives aspect of transportation, aspect of waste, and aspect energy respectively are Rp62.509.413.531, -Rp234.548.061 (first year) and -Rp189.735.061 (following year), and Rp4.677.239.959.
