Abstract The existence of forests as a life support system has provided benefits for human life, especially in the current era where environmental issues regarding climate change and global warming are starting to emerge. The existence of forest areas is called green open space or urban forest. The existence of urban forests is very important for the balance of the microclimate in urban areas. Langsa City Forest is an area with an area of about 10 hectares which functions for the preservation, harmony and balance of urban ecosystems which include environmental, social and cultural elements. Determination of the sample using purposive sampling method with random start. Sampling technique used 12 plots with an area of about 10 hectares, tree biomass calculation using allometric equations. Data obtained from the Langsa City Forest in the calculation of carbon in 12 plots, the plot that has the highest amount of carbon is 6 with a value of 225.74 tC/Ha and the plot that has the amount of carbon with the lowest value is 1 with a value of 16.54 tC/Ha. The average carbon value in Langsa City Forest is 119.07 tC/Ha. There are 5 plots that have the highest average value, namely plots 2, 6, 8, 9, and 10 also 7 plots have below the average value, namely plots 1, 3, 5, 7, 11 and 12. Total carbon plots in the forest Langsa City is 1428.84 tC/Ha with an average carbon in the area of 119.07 tC/Ha and a standard deviation of 65.35 tC/Ha. The information about carbon uptake on vegetation shows that the existence of urban forest is very important for the balance of the microclimate in urban areas of Langsa City.

Urban forestry has the potential to address many urban environmental and sustainability challenges. Yet in Africa, urban forest characterization and its potential to contribute to human wellbeing are often neglected or restrained. This paper describes the structure, diversity, and composition of an urban forest and its potential to store carbon as a means of climate change mitigation and adaptation in Kumasi. The vegetation inventory included a survey of 470,100-m2 plots based on a stratified random sampling technique and six streets ranging from 50 m to 1 km. A total of 3757 trees, comprising 176 species and 46 families, were enumerated. Tree abundance and species richness were left skewed and unimodally distributed based on diameter at breast height (DBH). Trees in the diameter classes >60 cm together had the lowest species richness (17%) and abundance (9%), yet contributed more than 50% of the total carbon stored in trees within the city. Overall, about 1.2 million tonnes of carbon is captured in aboveground components of trees in Kumasi, with a mean of 228 t C ha−1. Tree density, DBH, height, basal area, aboveground carbon storage, and species richness were significantly different among green spaces (p < 0.05). The diversity was also significantly different among urban zones (p < 0.0005). The DBH distribution of trees followed a modified reverse J-shaped model. The urban forest structure and composition is quite unique. The practice of urban forestry has the potential to conserve biological diversity and combat climate change. The introduction of policies and actions to support the expansion of urban forest cover and diversity is widely encouraged.

Roof Garden

<p>A garden is an outdoor relaxation area, set aside for the display of plants and other natural habitats solitary to human life. However, due to the reduced open space in urban areas, turning parks into gardens has become common. Therefore, a roof garden is an attractive option because it is private, and accessible to only certain people. Presently, the Study Program Landscape Architecture Universitas Trisakti, Jakarta, Indonesia, has a roof garden used to support certain subjects' practical activities.  However, the concept of a green pattern applied to the roof garden of this institution is not optimal. Therefore, this study aims to determine the design principles that have not been maximized in the roof garden of Study Program Landscape Architecture due to inaccuracy in the arrangement of the green pattern. This is descriptive research intended to describe and examine the characteristics, relationships, similarities, and differences of green patterns in the roof garden with other phenomena.</p>

AbstractEnvironmental problems in urban areas are a problem that never stops. That every community needs a healthy life, but this seems difficult to become a reality for urban communities because the population continues to increase every year so that land conversion occurs which results in increased air and water pollution. Therefore, the central government hopes that each region or region can provide RTH 30% of the city area. The purpose of this study is to analyze the enforcement of the City Forest Regulations in Surabaya and to find out the efforts of local governments in fulfilling urban forest land in urban areas. This study uses a normative juridical method. As part of RTH, the development of urban forests in Surabaya is very much needed by the community, therefore cooperation between the government and the community is needed in the management and development of urban forests. Fulfillment of urban forest areas in Surabaya can be done by maximizing the form of urban forest that has been regulated based on the City Forest Regulation, either in the form of channels, groups or scattered.Keywords: city forest; green open space; urbanAbstrakMasalah lingkungan hidup diwilayah perkotaan merupakan masalah yang tak kunjung berakhir. Bahwa setiap masyarakat membutuhkan hidup sehat, namun hal tersebut seolah sulit menjadi kenyataan bagi masyarakat perkotaan yang disebabkan karena jumlah penduduk yang tiap tahun meningkat sehingga terjadi pengalihfungsian lahan yang berakibat pada semakin meningkatnya pencemaran udara maupun pencemaran air. Oleh karena itu, pemerintah pusat mengharapkan bagi setiap wilayah atau daerah menyediakan RTH 30% dari luasan kota. Tujuan dilakukannya penelitian ini adalah untuk menganalisa pemberlakuan Perda Hutan Kota di Surabaya serta mengetahui upaya pemerintah daerah dalam memenuhi lahan hutan kota pada wilayah perkotaan. Penelitian ini menggunakan metode yuridis normatif. Sebagai bagian dari RTH, pengembangan hutan kota di Surabaya sangat dibutuhkan oleh masyarakat oleh karenanya diperlukan kerjasama antara pemerintah dengan masyarakat dalam pengelolaan dan pengembangan hutan kota. Pemenuhan luasan hutan kota di Surabaya dapat dilakukan dengan mamaksimalkan bentuk dari hutan kota yang telah diatur berdasarkan pada Perda Hutan Kota, yakni dapat dengan bentuk jelaur, mengelompok maupun menyebar.

Shuttle Run

The shuttle run exercise is a form of exercise that can improve agility. The zigzag run exercise is a form of agility training that involves the use of bollards and stakes. UM Palopo futsal players must have good dribbling skills. The conditions experienced by UM Palopo futsal players still often make mistakes in their dribbling skills. The lack of skills possessed by UM Palopo futsal players is due to the lack of agility training models that can support the achievements of futsal players. This study aims to reveal the effect of shuttle run and zig-zag run training on dribbling skill. The method used is a quasi-experimental (quasi-experimental). The population is 20 people from UKM Futsal UM Palopo. The sampling technique is purposive sampling. The data collection technique used the dribbling skill instrument and was analyzed by using the sig level t test. = 0.05.

The study examined the contribution of peri-urban forest to neighbourhood livelihoods in Abeokuta, Ogun State, Nigeria. Stratified sampling technique was adopted for the study. Four strata represent-ing different communities were selected; Ajegule, Ibode Olude, Ilugun Titun and Mawuko. From each stratum, twenty five respondents were randomly selected with a total of 100 respondents from the neighbourhood. Questionnaire was used as the instrument of data collection. The result showed that poverty line was N8,871.41 monthly and 41% of the respondents were categorised as poor (Poverty incidence). Household assets acquisition as poverty indicator showed that majority of the respondents could not afford luxury items such as cars (89%), generators (71%) and electric cookers (99%). Liveli-hood activities identified in peri-urban forest with respondents distribution were firewood collection 24%, wages 24%, snail gathering 7%, medicinal leaves collection 5%, hunting 8%, teak leaves collec-tion 21% and geological materials extraction 11%. The earnings and income shares by source indi-cated that forest contributed 17% of total income in Ajegunle, 15% in Ibode Olude, 18% in Ilugun Titun and 15% in Mawuko. This showed the contribution of peri-urban forest to welfare of the respondents in the neighbourhood. Consequently, it is recommended that conservation efforts must increase through forest policy for peri-urban forests coupled with adult literacy for adequate education to reduce de-pendence on forests in peri-urban areas to enable the forest impact positively through eco-services on the lives of residents in the locality.

Local diversity through site-dependent activities such as tourism and resource-based recreation, as well as resource extraction, may offer opportunities for regional development and restructuration. The small number of open spaces in urban areas is a factor in the considerably high pressure of life in the city center. Therefore, the existence of public open spaces in the city center, especially green open spaces in urban areas, is needed because of its function and role as a place for socialization and recreation as well as an alternative rest area with its fresh air in the midst of hectic activities in the city center. Public open space also serves as a place for people to relieve fatigue after a long hard work at a very low cost. This research aims to analyze the effectiveness and the efficiency of the management of the Environmental Study Tourism Park in the City of Probolinggo. The management of urban forest in the former “red are” idle land for ecological, educational and socio-economic purposes as a manifestation of public green open space in urban areas is developed into an Environmental Study Tourism Park. Based on the results of research on the performance of the government/management in providing services to the community regarding environmental education information is considered to be good enough because it is supported by certified experts in accordance with their fields and provide convenience to the community/educational institutions in terms of visiting and learning flora and fauna.
