"[Sektor pertanian, kehutanan dan penggunaan lahan lainnya (land use, land-use change and forestry/LULUCF) memiliki kontribusi hingga 20% untuk emisi gas rumah kaca. Salah satu skema yang dirancang sebagai upaya mitigasi perubahan iklim dari sektor pertanian, kehutanan dan penggunaan lahan lainnya (LULUCF) adalah program Reducing Emissions from Deforestation and Forest Degradation (REDD. Penelitian ini mengevaluasi program REDD+ di Taman Nasional Bukit 12 (TNBD) serta menganalisa skenario alternatif program REDD+ berdasarkan
hasil evaluasi yang telah dilakukan sebagai upaya mitigasi perubahan iklim. Evaluasi dilakukan untuk mencari sebab kegagalan penerapan program REDD+ di TNBD yang telah disosialisasikan sejak tahun 2011. Selanjutnya analisa skenario alternatif dilakukan guna meningkatkan nilai cadangan karbon dan agar program REDD+ dapat berjalan dengan baik. Analisa skenario alternatif dilakukan menggunakan program GIS (Sistem Informasi Geografis) dengan parameter cadangan dan emisi karbon untuk analisa neraca massa karbon. Berdasarkan analisa yang dilakukan, cadangan karbon pada tahun 2001 hingga 2008 berkurang
hingga 76 ton C/ha dan emisi karbon meningkat sebesar 95 ton C/ha. Dari 3 skenario alternatif yang dianalisa, skenario mengubah kebun homogen menjadi kebun campur menjadi skenario yang paling memungkinkan untuk dijalankan guna meningkatkan nilai cadangan karbon sekaligus menurunkan nilai emisi karbon di TNBD.;Agriculture, forestry, and other land use(land use, land-use change and forestry/LULUCF) contribute significantly to greenhouse gas emissions up to 20% globally. One of the designed schemes as climate change mitigation effort from agriculture, forestry, and other land use (LULUCF) is Reducing Emissions from Deforestation and Forest Degradation (REDD+) program, a scheme to reduce greenhouse gas emissions from deforestation and forest degradation and also conservation, sustainable management of forests and enhancement of forest carbon stocks. This study evaluate REDD+ program in Taman Nasional Bukit 12 (TNBD) and rearrange REDD+program scenario based on evaluation result as climate change mitigation effort. Evaluation performed to indicate the cause of REDD+ program application failure in TNBD that have been socialized since 2011. Furthermore scenario rearrengement was done to increase carbon stock value and improve the application of REDD+ program., Agriculture, forestry, and other land use(land use, land-use change and

"ABSTRAK
Digester anaerobik dapat digunakan untuk menangani masalah timbulan lumpur tinja sekaligus menerapkan energi terbarukan di Kota Depok. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan sampah makanan (SM) dan sampah kebun (SK) pada lumpur tinja (LT) terhadap optimasi produksi gas metan dan penurunan beban organik. Tiga variasi sampel yaitu LT-SM, LT-SK, dan LT-SM-SK dengan rasio volume 1:1 dan beban organik sebesar 15 gr VS/L dibandingkan dengan LT dalam uji BMP yang dilakukan selama 55 hari. Dari hasil uji BMP, dihasilkan produksi gas metan sebesar 149 ± 4,93 ml CH4/gr VS (LT), 302 ± 42,4 ml CH4/gr VS (LT-SM-SK), dan 75,4 ± 6,05 ml CH4/gr VS (LT-SK). Dengan efisiensi penurunan VS paling besar yaitu 38,4% (LT-SK) dan penurunan COD paling besar 82% (LT-SM-SK). Penambahan sampah makanan dan sampah kebun terbukti secara statistik memberikan pengaruh yang signifikan terhadap optimasi produksi metan pada LT-SM-SK dan penurunan beban organik pada LT-SK dan LT-SM-SK.

ABSTRACT
Anaerobic digester is an alternative technology to solve the issue of septage sludge treatment and implement renewable energy source in Depok. The research aims to understand the influence of food waste (SM) and garden waste (SK) addition to septage sludge (LT) towards methane yield optimisation and organic loading reduction. There are three variations of substrates LT-SM, LT-SK, and LT-SM-SK mixed with volume ratio 1:1 and organic loading rate 15 gr VS/L. It will be compared with septage sludge (LT) during 55 days incubation periode of BMP Assay. The results of BMP Assay shows that LT, LT-SM-SK, and LT-SK yielded 149 ± 4,93 ml CH4/gr VS, 302 ± 42,4 ml CH4/gr VS and 75,4 ± 6,05 ml CH4/gr VS of methane gas respectively. The biggest VS and COD reduction occured are 38,4% (LT-SK) and 82% (LT-SM-SK) respectively. The statistic test proved that there is significant increase of methane yield and organic loading reduction due to the food waste and garden waste addition in the anaerobic digestion of septage sludge."
