Gajahmada Street is one of the main streets in the city of Semarang. The location is very strategic, which connects the Golden Triangle Region in Semarang City which is the center of the city. As a city center, transportation activities in the area are very high. Transportation activities produce carbon dioxide emissions. The accumulation of carbon dioxide emissions is dangerous for health and the environment. Semarang City Government provides green open space along the road section to reduce carbon dioxide emissions. The purpose of this study was to determine the vegetation resilience to absorbing carbon dioxide at that location. The data collection method uses literature collection and field observations. The results showed the ability of green open space to absorb carbon dioxide emissions is 1.218,7 tons/ha/year. While the emissions produced are 6.832 tons/year, meaning that there is residual carbon dioxide that is not absorbed, that is 5.613,3 tons/year.

Jakarta was developed started from the coastline and gradually moved to the centre of the city which left the coastal area remain untouch. The development of Jakarta which only oriented on capitalism cause in a lack of public space for the community, which make public coping with the issues independently. The roads in the housing area and villages was used by local residents as a space to socialize with neighbors or a place to do activities. There are still lots of kampung remained in Muara Baru which located in North Jakarta, but not facilitated by public space and open space to accommodate the citizen’s need to socialize and do their activity, so they carried out those activities in the middle of the road or alley which can disturb the traffic and endangered other people’s lives.  This phenomenon indicates that the community's need for public space is very high and needs to be anticipated immediately in order to avoid environmental and social degradation. The purpose of this project is to become a linkage that connect people with the surrounding environment, as well as humans with other humans, while this project also help the economy and home industry businesses, which bring in money to help the economy of local citizens, and cause positive interactions, such as knowledge exchange and development in economic aspects. AbstrakPembangunan kota Jakarta awalnya dimulai dari area pinggir laut yang kemudian semakin berkembang ke pusat kota, seiring berlangsungnya pembangunan di pusat kota, daerah pinggir/pesisir mulai ditinggalkan dan tidak tersentuh. Pengembangan kota Jakarta yang hanya berorientasi pada kepentingan kapitalis juga mengakibatkan kurangnya ruang publik bagi masyarakat, sehingga  mengakibatkan masyarakat mengatasinya secara mandiri. Jalan-jalan di dalam perumahan hingga perkampungan yang difungsikan oleh warga setempat sebagai ruang untuk bersosialisasi dengan tetangga atau tempat melakukan aktivitas. Kawasan Muara Baru yang terletak di wilayah pesisir Jakarta bagian Utara, masih terdapat banyak area perkampungan, tetapi tidak difasilitasi oleh ruang publik atau ruang terbuka sehingga untuk melakukan kegiatan berinteraksi dan beraktivitas, dilakukan di jalan/lorong kecil didepan rumah, yang dapat mengganggu lalu lintas dan juga membahayakan keselamatan warga dan juga pengguna jalan. Fenomena ini menandakan bahwa kebutuhan masyarakat akan ruang publik sangat tinggi dan perlu segera diantisipasi agar tidak terjadi degradasi lingkungan dan sosial, sehingga tujuan dari proyek ini adalah sebagai linkage yang menggabungkan manusia dengan lingkungan di sekitarnya, serta manusia dengan manusia lainnya, selain itu juga untuk membantu perekonomian dan usaha industri rumahan, yang dapat dilakukan serta menghasilkan uang untuk membantu perekonomian warga, serta menimbulkan interaksi positif, seperti pertukaran ilmu dan pembangunan aspek ekonomi, yang ke depannya akan menghasilkan kemajuan pada kota Jakarta dengan aspek sosial dan ekonomi yang seimbang.

Abstract An eddy covariance station was installed in the city center of Firenze, Italy, to measure carbon fluxes at half-hourly intervals over a mostly homogeneous urban area. Carbon dioxide (CO2) emission observations made over an initial period of 3.5 months were compared with indirect estimates of CO2 emissions based on inventory data sources of vehicle circulation and natural gas consumption for domestic heating and cooking. Such a comparison provided proper evaluation of the measurements. Using seasonal dynamics of observed fluxes, the overall CO2 source of the city center was partitioned into its major components (i.e., road traffic and domestic heating). Results were directly compared with CO2 source estimates based on inventory sources.

Kota Semarang mengalami peningkatan pergerakan lalu lintas setiap tahunnya, khususnya  Kecamatan Semarang Tengah, yang memiliki fungsi sebagai kawasan pusat perbelanjaan, perdagangan dan jasa, perkantoran, dan pendidikan. Pemerintah Kota Semarang telah berupaya mengatasi permasalahan lalu lintas dengan menerapkan sistem satu arah pada ruas Jalan Gajahmada, Jalan Pandanaran, Jalan MH. Thamrin, Jalan Pemuda, Jalan Imam Bonjol Selatan, Jalan Kapten Piere Tendean, dan Jalan Indraprasta. Penelitian ini dilakukan untuk mengetahui gambaran efektivitas atas penerapan sistem satu arah pada ruas jalan tersebut dengan menggunakan metode analisis deskriptif dan kuantitatif hasil keluaran EMME2 versi 9.5. Hasil dari penelitian ini yakni setelah diterapkannya sistem satu arah masih terdapat ruas jalan yang mengalami penurunan kinerja jalan, yaitu ruas jalan Imam Bonjol Selatan belum sesuai dengan persyaratan fungsi jalan karena lebar badan jalannya hanya 10 meter sedangkan dalam persyaratan untuk fungsi jalan arteri sekunder lebar badan paling sedikit 11 meter, ruas Jalan Kapten Piere Tendean dan Pandanaran nilai DS 0.75 pada waktu sore hari dan berada pada tingkat pelayanan D pada ruas Jalan Pandanaran sedangkan tingkat pelayanan E berada pada ruas Jalan Kapten Piere Tendean. Selain itu, pada ruas Jalan Imam Bonjol Selatan, Kapten Piere Tendean, dan Pandanaran masih belum sesuai dengan indikator kinerja sistem jaringan jalan untuk meminimalisasi atau mengurangi ketertundaan total dan panjang perjalanan total karena kecepatan perjalanan menurun dan kapasitas jalan belum mampu menampung beban lalu lintas. Solusi penanganan yang dilakukan adalah nilai DS harus 0.75 dan maksimal menunjukkan ditingkat pelayanan C, Jalan Kapten Piere Tendean, dan Jalan Pandanaran, pelebaran jalan 1 meter pada ruas Jalan Imam Bonjol Selatan dan pengaturan off street parking pada ruas Jalan Imam Bonjol Selatan, Kapten Piere Tendean, dan Pandanaran. Kata kunci: EMME2 versi 9.5, kinerja sistem jaringan jalan, permasalahan lalu lintas, sistem satu arah.   Performance Analysis of One - Way Roads in Central Semarang District, Semarang : The city of Semarang is experiencing an increase in the movement of traffic every year, especially in Central Semarang District which has a function as a shopping center, trade and service area, office area, and education area. The Semarang City Government has tried to overcome traffic problems by implementing a one - way system on Gajahmada, Pandanaran, MH. Thamrin, Pemuda, Imam Bonjol Selata n, Piere Tendean, and Indraprasta streets . This study was conducted to determine the effectiveness of the implementation of the one - way system on the road using the analysis method, which wa s descriptive and quantitative output of EMME2 version 9.5. The re sults showed that after the implementation of one - way system, there was still decreased performance in some roads. The road segment in Imam Bonjol Selatan street had not fulfill the requirements for road functions because the width of the road wa s only 10 meters, mean while according to the requirements for secondary arterial road functions it should be at least 11 meters. The DS value of Piere Tendean and Pandanaran Roads was 0.75 in the afternoon . Furthermore, the level service of Pandanaran Road was D w hile Captain Piere Tendean Road section was E . In addition, Imam Bonjol Selatan, Captain Piere Tendean and Pandanaran Roads we re not in accordance with the performance indicators for the road network ing system to minimize or reduce total delays and total t rip length because travel speeds were declining and road capacity had not been able to accommodate traffic loads. T o overcome this problem the DS value must be 0.75 and the maximum service level should be C in Piere Tendean and Pandanaran Road s , widening 1 meter road on Imam Bonjol Selatan section, and setting off street parking on Imam Bonjol Selatan Road, Captain Piere Tendean, and Pandanaran. Keywords : EMME2 version 9.5, road network system performance, traffic problems, one - way system

Sustainable urban development leads to the creation of livable cities. The Green Open Space (GOS) of City requires the quality of life requirements to support the ecological, socio-cultural, and urban economic functions. In Indonesia, the provision of GOS is the city government’s responsibility, which has to carried out transparently and implemented with the involvement of stakeholders. The limited funding for the provision and improvement of the quality of GOS by the city government has developed a CSR scheme from the private sector. This CSR governance model enriches the use of CSR in addition to social assistance or charity activities, which can realize for the wider city community. The city government’s role in using CSR models is significant to ensure transparency of costs, accountable design policies, and their implementation and maintenance.

Reduce Carbon Dioxide

The Paris Agreement, adopted in December of 2015 at the 21st session of the UNFCCC Conference of the Parties and effected from November of 2016, coordinates the efforts of states to reduce greenhouse gas (GHG) emissions, including carbon dioxide. One of its largest emitters to the atmosphere is the metallurgical industry. Among the proposed ways to reduce carbon dioxide emissions is the widespread use of hydrogen in the ferrous metallurgy. An overview of the problems that the ferrous metallurgy will face when replacing carbon-containing fuels with hydrogen is presented. It was noted that the use of hydrogen in the ferrous metallurgy contains such technological risks as high cost in comparison with currently used fuels and reducing agents; explosion hazard and corrosion activity, the need for a radical reconstruction of thermal units when using hydrogen instead of traditional for the ferrous metallurgy natural, coke and blast furnace gases, as well as solid fuels. It is shown that minimizing these risks is not always possible or economically feasible, and the result of using hydrogen in the ferrous metallurgy instead of carbon-containing fuel from the point of view of reducing greenhouse gas emissions may be low with a significant increase of economic and social risks.
