"Jakarta memiliki komitmen menurunkan emisi untuk mencapai tujuan menjadi kota dengan emisi rendah karbon. Pemerintah provinsi DKI Jakarta telah memiliki kebijakan Rencanan Pembangunan Rendah Karbon Daerah (RPRKD) dalam upaya menurunkan emisi gas rumah kaca untuk menjadikan Jakarta sebagai kota yang berkelanjutan. Namun saat ini Jakarta masih memiliki ketergantungan yang tinggi terhadap sistem energi nasional. Untuk itu perlu dilakukan riset pemodelan dekarbonisasi sistem energi dari sisi suplai dan permintaan dengan peningkatan bauran teknologi yang efisien dan penggunaan energi terbarukan agar Jakarta dapat menjadi kota yang memiliki emisi CO2 yang rendah. Pemodelan sistem energi dilakukan dengan pendekatan optimisasi teknologi bottom-up menggunakan perangkat lunak TIMES. Skenario Low Carbon Scenario (LCS) pada optimisasi penelitian ini dapat menurunkan emisi paling signifikan, dimana penurunan emisi mencapai 40,92% emisi sebesar 11.167 kt CO2 pada tahun 2050. Biaya investasi teknologi pada skenario LCS adalah sebesar 21.995 miliar USD pada tahun 2050, dengan peta jalan sisi pengguna yaitu penggunaan lampu LED untuk penerangan, AC inverter untuk pendinginan, kompor listrik untuk memasak, penerapan kebijakan bangunan hijau untuk sektor bangunan, kendaraan listrik pada sektor transportasi, penggunaan rooftop solar PV, pembangkit PLTSa, dan CCHP pada sisi suplai listrik.

Jakarta has a commitment to reduce emissions and become a low-carbon city. The provincial government of DKI Jakarta has implemented the Low Carbon Regional Development Plan (RPRKD) to lower greenhouse gas emissions and promote sustainability in the city. However, Jakarta still heavily relies on the national energy system. Therefore, research is necessary to model the decarbonization of the energy system, considering both the supply and demand sides. This research focuses on increasing the adoption of efficient technologies and renewable energy sources to achieve low CO2 emissions in Jakarta. The energy system modeling employs a bottom-up technology optimization approach using TIMES software. The Low Carbon Scenario (LCS) identified in this research optimization yields the most significant reduction in emissions. It predicts a decrease of 40.92%, equivalent to 11,167 kt CO2 emissions by the year 2050. The estimated investment cost for the required technologies in the LCS scenario is $21.995 billion in 2050. The roadmap for the LCS scenario encompasses the use of LED lighting, inverter air conditioners, electric stoves, the implementation of green building policies in the building sector, the high adoption of electric vehicles for transportation, the utilization of rooftop solar photovoltaic (PV) systems, Waste to Electricity (WtE) power plants, and Combined Cooling, Heating, and Power (CCHP) systems for electricity supply."

"ABSTRAKIsu energi global merupakan suatu topik masalah yang tidak baru lagi. Peningkatan produksi energi yang menunjukkan pengaruh signifikan adalah dengan modifikasi bahan bakar fosil dengan bahan bakar terbarukan, salah satunya adalah dengan bioethanol. Salah satu kendala dalam produksi bioethanol fuel-grade adalah sulitnya memenuhi standar kadar air yang berada pada angka 1.0 v/v sesuai standar Amerika ASTM D4806 karena terjadinya fenomena azeotrope. Salah satu metode yang paling hemat energi adalah dengan adsorpsi. Salah satu kriteria dehidrasi bioethanol dengan metode ini dinilai memiliki kinerja baik adalah saat kapasitas adsorpsi dari adsorbent semakin besar. Kapasitas ini salah satunya dipengaruhi oleh material dari adsorbent yang digunakan. Material adsorbent yang diuji kapasitasnya dalam penelitian ini adalah polyvinyl alcohol PVA , zeolit, dan karbon aktif. Penelitian ini dilakukan dengan menganalisis hubungan serta pengaruh jenis adsorbent dan konsentrasi awal campuran terhadap kapasitas adsorpsi menggunakan pemodelan Langmuir untuk grafik hubungan konsentrasi akhir etanol dengan kapasitas adsorpsi. Adsorpsi karbon aktif memiliki kapasitas yang dua kali lipat lebih besar dibandingkan dengan PVA, dan 20 lebih besar dari zeolit. Analisis selektivitas menunjukkan bahwa zeolit sebagai adsorben lebih selektif terhadap air dibandingkan dengan kedua adsorben lainnya.

ABSTRAKGlobal energy issue is no longer a new topic. The expansion of energy production proven to show significant influence is the fossil fuel modification by blending it with liquid renewable fuel, such as bioethanol. Bioethanol must achieve fuel grade standard to qualify as gasoline, one of the specification is to have moisture content of 1.0 v v or less, as regulated by ASTM D4806. This parameter is a challenging one to achieve, because water ethanol mixture will encounter the azeotrope phenomenon when the mixture undergoes a common distillation process and reach 95.6 v v of ethanol. One of the dehydration method that use less energy is adsorption. One of the efficiency consideration of bioethanol dehydration with adsorption is its adsorption capacity. Adsorption capacity is influenced by the material of adsorbent, operational temperature and time. The material being tested in this research are poly vinyl alcohol PVA , zeolite, and activated carbon. This research will analyze the dependency and influence of adsorbent type and mixture rsquo s initial concentration towards adsorption capacity utilizing a Langmuir model. The result of this study showed that the activated carbon has the highest parameter capacity, which is almost twice as much than PVA and 20 larger than zeolite. Whereas the result of selectivity study between the three prove that zeolite has better selectivity."

Greenhouse gas emissions, which highly contributes to the climate change, largely come from developing country. Organization of Islamic Cooperation (OIC), as a substantial part developing countries, despites having a significant increase of greenhouse gas emission (over 100%) during 1990 to 2013, also has a high increase in share of CO2 from their total greenhouse gas emissions (7%). This is manily due to combustion of fossil fuel. Moreover, OIC is also faced with a fast growing economy, this means there will a need of more energy input to produce, which in turn lead to larger emissions. However, energy mix of OIC is still dominated by fossil fuel (97%). Therefore, OIC needed to implement a set of policy to reduce their CO2 emissions. According to Internasional Energi Agency, improving energi efficiency and utilzation of renewble energi are solution to mitigate and limitate the global warming. This study aims to examine the impact of implementation of energy efficiency and utilization of renewable energi to reduce CO2 emissions in OIC using STIRPAT model and random effect model of estimation from 2010 to 2017 data. The result show that both energi efficiency and renewable energi have a negative impact on CO2 emissions dan implementation of renewable energy has larger impact than improving energi efficiency. "
