" Setyawan AD. 2009. Effect of global warming on plant evolution and diversity; lessons from the past and its potential
recurrence in the future. Nusantara Bioscience 1: 43-52. Lessons from the past show that global warming and glaciation is a natural
cycle of repeated, the trigger factor is not always the same, but global warming is always accompanied by elevated levels of CO2 and
greenhouse gases in the atmosphere which cause the other rising global temperatures. Present and destruction of various plants and other
living makhluh continue to happen from time to time. Every era has its life form, as a mirror of global environmental conditions at the
time. Biodiversity is not always the same between one period of global warming are with the next global warming or one period of
glaciation that one with the next glaciation, although new breeds always show traces the evolution of his ancestors. Human is one of the
agents of global warming that began with the development of agricultural systems since 8000 years ago. The impact of climate change
due to global warming should continue to be wary of. Based on past experience, global warming is always followed by mass extinctions,
but various forms of life will still survive even though its shape is almost certainly not the same as before. Living organisms can survive
it will evolve into new taxa that are different from its parental taxa. Men who were present at that time probably were not men who are
present at this time, given Homo sapiens may have been extinct for not being able to adapt or otherwise has evolved into a new man
who may no longer show characteristics of human wisdom."

"Changes in marine ecology are normal, because the earth is dynamic, and are getting worse and faster since human are involved in their processes, indicating the Anthropocene Era begins. Consequently, three parameters to measure the quality of the earth for living, i.e. climate changes, rate of biodiversity loss, and nitrogen cycles, have been over the maximum thresholds. In general, changes in marine ecology are caused by phenomena that are occuring in global scale e.g. increasing of CO2 emission, global warming, and ocean acidification, regional scale e.g. overfishing, and changes in oceagraphical processes, rain and storm, and local scale e.g. eutrophication, sedimentation, pollution, biological invasions, herbivory, and diseases. Result of reviews shows that major causes of changes in marine ecology in Indonesia may be global warming, overfishing, and coastal pollution. As a result, species richness, abundance, distribution, and community structure of marine ecosystems in Indonesia change significantly."

"Latar Belakang : Global warming atau peristiwa meningkatnya suhu rerata bumi disebabkan oleh peningkatan konsentrasi karbondioksida (CO2) pada atmosfer bumi. Peningkatan kadar karbondioksida ini berpengaruh terhadap kesehatan melalui berbagai cara. Dalam tubuh kondisi kadar karbondioksida yang tinggi atau hiperkapnea dapat memberikan pengaruh pada tubuh salah satu nya adalah peningkatan produksi Reactive Oxygen Species (ROS) yang dapat menyebabkan stres oksidatif. Dengan menggunakan sel Peripheral Blood Mononuclear Cell (PBMC), kadar ROS terutama superoksida yang diproduksi akibat paparan CO2 tinggi dapat dideteksi dengan menggunakan dihydroethidium (DHE) assay.
Tujuan : Penelitian ini dilakukan untuk melihat efek pemaparan pada kadar CO2 tinggi terhadap perubahan produksi superoksida pada sel PBMC.
Metode : Sel PBMC diinkubasi pada kadar CO2 yang berbeda yaitu kadar tinggi sebesar 15% dan kontrol 5% CO2. Produksi superoksida pada sel tersebut dapat dilihat menggunakan DHE assay dengan melihat perubahan nilai absorbansi pada fluorometer. Hasil yang didapatkan adalah nilai absorbansi per sel yang menggambarkan kadar superoksida untuk tiap satu sel PBMC.
Hasil : Pemaparan sel PBMC pada kondisi tinggi CO2 (15% CO2) selama 24 jam dan 48 jam secara signifikan meningkatkan produksi superoksida bila dibandingkan dengan kontrol (5% CO2) pada sel PBMC. Namun terdapat penurunan yang signifikan antara paparan tinggi CO2 selama 48 jam bila dibandingkan dengan paparan tinggi CO2 selama 24 jam. Dari sini dapat disimpulkan bahwa paparan tinggi CO2 dapat meningkatkan laju produksi superoksida pada sel PBMC. Selain itu terdapat penurunan kadar superoksida pada sel PBMC apabila lama paparan CO2 tinggi lebih dari 24 jam.
Kesimpulan : pemaparan kadar CO2 tinggi pada sel PBMC selama 24 jam dan 48 jam akan meningkatkan laju produksi ROS terhadap kontrol. Penurunan kadar superoksida pada inkubasi CO2 tinggi selama 48 jam menunjukan ada nya pengurangan kadar superoksida apabila lama inkubasi lebih dari 24 jam.
......Background: Global warming or the increase in the average temperature of the earth is caused by an increase in the concentration of carbon dioxide (CO2) in the earth's atmosphere. Increased levels of carbon dioxide affect health in various ways. In the body of conditions high carbon dioxide levels or hypercapnea can give effect to the body one of them is an increase in the production of Reactive Oxygen Species (ROS) which can cause oxidative stress. By using Peripheral Blood Mononuclear Cell (PBMC) cells, ROS levels, especially superoxide produced due to high CO2 exposure can be detected using dihydroethidium (DHE) assay.
Objective: This study was conducted to see the effect of exposure to high CO2 levels on changes in superoxide production in PBMC cells.
Methods: PBMC cells were incubated at different CO2 levels, namely a high level of 15% and a control of 5% CO2. Superoxide production in these cells can be seen using the DHE assay by looking at changes in absorbance values on the fluorometer. The results obtained are absorbance values per cell that describe the levels of superoxide for each one PBMC cell.
Results: Exposure of PBMC cells under high CO2 conditions (15% CO2) for 24 hours and 48 hours significantly increased superoxide production when compared to controls (5% CO ¬ 2) on PBMC cells. However, there was a significant decrease between 48 hours of high CO2 exposure compared to 24 hours of high CO2 exposure. From this it follows that high exposure to CO2 can increase the rate of superoxide production in PBMC cells. In addition there is a decrease in superoxide levels in PBMC cells if the duration of high CO2 exposure is more than 24 hours.
Conclusion: exposure to high CO2 levels in PBMC cells for 24 hours and 48 hours will increase the rate of superoxide production to control. Decrease in superoxide levels in incubation of high CO2 for 48 hours shows that there is a reduction in superoxide levels if the incubation time is more than 24 hours."

"Sektor industri merupakan salah satu sektor yang beperan penting dalam penurunan Gas Rumah Kaca (GRK), salah satunya yang sedang berkembang yaitu industri air bersih dan air limbah. Hingga saat ini, sudah banyak perlakuan pemerintah dalam menurunkan emisi di sektor air limbah, namun tidak pada sektor air bersih. Di sisi lain, Indonesia sedang mengejar pembangunan infrastruktur air bersih hingga 60% terlayani oleh PDAM. Sehingga, sektor air bersih menjadi sektor yang harus diperhatikan termasuk dalam GRK yang dihasilkan.
Penelitian ini bertujuan untuk mengestimasi emisi CO2 sebagai emisi GRK dari pengolahan air bersih, yaitu Instalasi Pengolahan Air (IPA) Legong dan IPA Citayam yang mewakili Kota Depok, dan melakukan pengembangan skenario guna menurunkan emisi CO2. Estimasi emisi CO<2 menggunakan metode IPCC, model matematika, dan stokiometri. Total emisi CO2 yang dihasilkan dari pengolahan air bersih pada tahun 2018 yaitu 0,458 kg CO2/m3 dengan kapasitas produksi 2.313 m3/jam, dengan sumber emisi terbesar yaitu kegiatan konsumsi listrik untuk operasional IPA, transportasi bahan kimia, konsumsi koagulan, dan yang paling rendah yaitu penggunaan genset.
Dari hasil analisis dan pengembangan skenario, direkomendasikan perencanaan reservoir untuk mengurangi operasional pompa intake dan membuat emisi CO2 yang dihasilkan berkurang 1,6%. Rekomendasi lainnya yaitu dengan asumsi pembangkit listrik utama berasal dari tenaga surya, sehingga emisi CO2 yang dihasilkan berkurang 15,3%. Karena itu, pemanfaatan energi alternatif merupakan startegi utama dalam menurunkan emisi CO2 dari pengolahan air bersih.
......The industrial sector is one of the important sectors in reducing GHGs, one of them is the water and wastewater industries. Until now, there has been a lot of government treatment in reducing emissions in the wastewater sector, but not in the clean water sector. On the other hand, Indonesia is pursuing the development of clean water infrastructure, up to 60% is served by PDAM. Thus, the clean water sector becomes a sector that must be considered including the GHG emission.
This study aims to estimate CO2 emissions as GHG emissions from water treatment, namely the Legong Water Treatment Plant (WTP) and Citayam WTP which represent Depok City, and develop scenarios to reduce CO2 emissions. CO2 emissions is calculated using the IPCC method, mathematical models, and stochiometry. The total CO2 emissions generated from the treatment of clean water in 2018 were 0.458 kg CO2/ m3< with a production capacity of 2,313 m3/hour, with the largest source of emissions are electricity consumption activities for IPA operations, chemical transportation, coagulant consumption, and the lowest, that is use of generator set.
From the results of scenario analysis and development, reservoir planning is recommended to reduce the intake pump operation and make the CO2 emissions produced reduced by 1.6%. Other recommendations are assuming that the main power plant comes from solar power, so the CO2 emissions produced are reduced by 15.3%. Therefore, alternative energy utilization is the main strategy in reducing CO2 emissions from processing clean water."

"Biodiesel merupakan merupakan salah satu alternatif solusi untuk mengurangi penggunaan bahan bakar berbasis minyak bumi. Bahkan kini penggunaan biodiesel dengan basis minyak kelapa sawit telah mulai dikomersilkan. Namun penggunaan minyak kelapa sawit sebagai bahan baku biodiesel erat kaitannya dengan isu-isu lingkungan. Penelitian ini dilakukan untuk menganalisis besar emisi dan dampak lingkungan yang dihasilkan dalam produksi biodiesel, sekaligus membandingkan dampaknya dengan dampak lingkungan solar. Analisis dilakukan dengan metode Life Cycle Assessment (LCA) dengan menggunakan perangkat lunak SimaPro. Data yang digunakan merupakan data primer perusahaan dengan dilengkapi data sekunder dari literatur serta database global. Pendekatan batasan sistem yang diterapkan adalah cradle-to-gate, yaitu dimulai dari tahap kebun benih, pembibitan, perkebunan, pabrik kelapa sawit, stasiun penyimpanan, dan pabrik rafinasi. Metode analisis dampak lingkungan yang digunakan adalah metode ReCiPe 2016 midpoint (H). Berdasarkan perhitungan, dampak lingkungan global warming potential yang dihasilkan 1 ton biodiesel sebesar 959,56 kg CO2-eq. Dibandingkan dengan nilai GWP solar, apabila dilakukan penggantian bahan bakar komersil menjadi B20 didapatkan perhitungan bahwa akan terjadi penurunan dampak GWP sebesar 13% atau 2,46 juta ton CO2-eq selama satu tahun di Indonesia. 
......Biodiesel is considered as a viable alternative solution to reduce the consumption of fossil fuel-based fuels. The utilization of biodiesel derived from palm oil has started to be commercialized. However, the use of palm oil as a feedstock for biodiesel production is closely associated with environmental issues. This study aims to analyze the magnitude of emissions and environmental impacts generated in biodiesel production and compare them with the environmental impacts of conventional diesel fuel. The analysis is conducted using the Life Cycle Assessment (LCA) method with the SimaPro software. The data used include primary data from the company, supplemented with secondary data from literature and global databases. The system boundary applied in this study is cradle-to-gate, starting from the seed production, nursery, estate, palm  oil mill, bulking, and refinery. The environmental impact assessment method used is the ReCiPe 2016 midpoint (H). Based on the calculations, the global warming potential (GWP) impact generated by 1 ton of biodiesel is estimated at 959.56 kg CO2-eq. When compared to the GWP value of conventional diesel fuel, replacing commercial fuel with a blend of 20% biodiesel (B20) would result in a 13% reduction in GWP impact, equivalent to 2.46 million tons of CO2-eq over one year in Indonesia."
