Abstract The urban forest is part of the public green open space (RTH) formed from tree vegetation that affects temperature and humidity and reduces wind speed to provide comfort for residents in the vicinity. One of the urban forests in Medan is the Balai Wilayah Sungai (BWS) II Medan. Therefore, vegetation density has an influence on temperature and which affects the quality of urban forests. This study aimed to identify the structure and composition of the BWS II Medan urban forest vegetation. The vegetation analysis method used in this study is a combination method between the path method and the plotline method. The vegetation data that has been obtained is then processed to obtain the Important Value Index (IVI) and the Plant Species Diversity Index (H’). The results showed that the woody plants found in the urban forest of BWS II Medan were 20 species with the composition of seedlings of four species (26 individuals), saplings of twelve species (49 individuals), poles of eleven species (39 individuals) and trees of ten species (141 individuals). The species that dominates at the tree level is Trembesi (Samanea saman), with an IVI value of 118.16%. Meanwhile, the dominant plant species at the seedling, sapling, and pole levels were Mahoni (Swietenia mahagoni), with IVI values of 78.67%, 55.73%, and 103.62, respectively. Therefore, the level of diversity in the BWS II Medan Urban Forest for saplings is classified as moderate, while seedlings, poles, and trees are classified as low.

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.

Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea. The species diversity index at the Arboretum has a value of 2.74, Campus S1 Forestry Untan with a value of 2.19 and Pendopo Park with a value of 2.02. This value indicates that species diversity in green open space is classified as medium.Keywords: butterfly diversity, green open space, bioindicator

Urban forest is one form of green open space. Urban forests play an important role in maintaining the sustainability of ecological functions in a city. This role could only run optimally with the availability of urban forests. The purpose of this study is to analyze the status of land ownership and analyze the efforts that can be made in maintaining urban forests. This study used image analysis, interviews, and field observations. From the results of this study, the status of urban forests based on the Mayor of Bandar Lampung Decree in 2010 had different statuses at each location. The urban forest ownership does not exclusively belong to the government. Of the 5 locations, only 1 location owned by the Bandar Lampung City Government, with 1 location that is not recognized (problematic), 1 location did not have a certificate of rights yet, and 2 other locations were private locations. The best effort that could be made to maintain the existence of urban forests is to control urban forest land as ownership in the name of the City Government with the support of certain regulations that can be done.

Salah satu indikator yang digunakan untuk mengukur keberhasilan kegiatan reklamasi adalah dengan cara menghitung jumlah jenis vegetasi yang tumbuh pada areal reklamasi tersebut. Penelitian ini bertujuan untuk mengkaji variasi umur tanaman terhadap struktur dan komposisi vegetasi di areal reklamasi tambang (KRPT) PT Kideco Jaya Agung (PT KJA), Paser, Kalimantan Timur melalui kegiatan monitoring dan evaluasi vegetasi tahunan. Lokasi studi mencakup 13 (tiga belas) KRPT dengan umur tanaman 1-13 tahun. Nilai kerapatan vegetasi tertinggi pada masing-masing kategori adalah 1.125 individu/ha (KRPT umur 12 tahun) untuk tingkat pohon, 650 individu/ha (KRPT umur 10 tahun) untuk tingkat pancang dan 525 individu/ha (KRPT umur 8 tahun) untuk tingkat semai. Hasil penelitian ini juga menunjukkan bahwa terdapat 51 jenis vegetasi yang berasal dari 22 famili tanaman ditemukan pada areal konsesi PT KJA site Roto Samurangau. Dimana 32 diantaranya merupakan jenis tanaman yang tumbuh secara alami, sedangkan 19 jenis vegetasi lainnya merupakan jenis tanaman pokok. Berdasarkan variasi nilai kuantitatif pada masing-masing lokasi yang diamati, tidak tampak bahwa semakin tua umur tanaman, maka semakin tinggi pula nilai kerapatan vegetasi, basal area, dan kehadiran jenisnya. Namun, meskipun secara umum menurun, keragaman jenis pohon pada tanaman reklamasi yang lebih tua cenderung lebih beragam. Hal tersebut dikarenakan berbedanya situasi dan kondisi masing-masing KRPT yang diamati, seperti perbedaan kondisi tanah, jenis tanaman, dan jarak lokasi studi dengan hutan alam. Berdasarkan hasil identifikasi dan inventarisasi yang dilakukan pada penelitian ini diketahui bahwa KRPT dengan umur tanam 12 tahun memiliki komposisi vegetasi yang paling beragam, dimana dari 19 jenis vegetasi, 14 diantaranya merupakan jenis tanaman yang tumbuh secara alami. ABSTRACTThe one indicator used to measure the reclamation succession activities is by calculating the number of vegetation species that grow in reclamation area. This study aimed to determined the variations in plant age on the vegetation structure and composition in the mine reclamation area (KRPT) of PT Kideco Jaya Agung (PT KJA), Paser, East Kalimantan through annual vegetation monitoring and evaluation activities. The study sites cover 13 (thirteen) KRPTs with a plant age of 1-13 years. The highest vegetation density values in each category were 1,125 individuals/ha (12 years old KRPT) for the tree level, 650 individuals/ha (10 years old KRPT) for the sapling level and 525 individuals/ha (8 years old KRPT) for the seedling level. Present study also showed that there were 51 species of vegetation from 22 plant families found in the concession area of PT KJA, 32 are naturally species while others 19 species are main vegetation. Based on the variation of quantitative values at each location observed, it was not appeared that the older plant age affected to the higher value of vegetation density, basal area, and species presence. However, although it was generally declined, tree species diversity in older reclaimed plants tended to be more diverse. This is probably due to the different situations and conditions of each observed KRPT, such as differences in soil conditions, plant species, and the distance between study site and natural forest. The result of plant species identification and inventory showed that KRPT with a planting age of 12 years had the most diverse vegetation composition, where from 19 species there are 14 species of them grown naturally

Abstract. Darmawati, Mulyadi A, Suwondo, Harto S. 2021. The diversity and vegetation structure based on growth levels at an urban green campus in Pekanbaru City, Indonesia. Biodiversitas 22: 5123-5132. The Bina Widya campus of the University of Riau (UNRI), Pekanbaru, Indonesia has the green open space (GOS) in its area and there are many species of vegetation. In a green open space, variables like diversity and vegetation structure must be considered based on growth levels, this study intended to determine the composition, structure, and diversity of vegetation.The results showed that there were 33 species of trees, 29 species of poles, 16 species of saplings, and 8 species of seedlings from 44 species belonging to 22 families. There were 874 individuals which consisted of 534 trees, 207 poles, 87 saplings, and 46 seedlings. The most common species found was Swietenia macrophylla King (Meliaceae) with 289 individuals. The highest Important Value Index of vegetation species at each growth level was the tree of Alstonia scholaris (L) R.Br (300%, location IX), the pole of Hibiscus tiliaceus L. (300%, location VII), saplings of Vitex pinnata L. (300%, location IV), and S. macrophylla King (300%, locations I), seedlings of S. macrophylla King (300%, location I), and Garcinia mangostana L (300%, location IX). We did not find vegetation species at the levels of sapling or seedling in locations of II, III, V, VI, and VIII. It is necessary to replant the vegetation. The highest Species Diversity Index (H') at location X was trees (2.34), poles (2.28), saplings (1.77), and seedlings (1.17). The average H’ vegetation at Bina Widya Campus UNRI was 2.44 (medium). Vegetation on the Bina Widya Campus is fairly steady in terms of delivering advantages for human environmental services.

Long drought and uncontrolled human activities resulted in R. Soerjo Prigen Pasuruan Grand Forest Park experiencing fire. Adverse impacts on vegetation can result in vegetation death. Damage caused by fire to vegetation can lead to succession which can be seen from the composition and structure of forest vegetation. The purpose of this study was to determine the effect of environmental parameters, structure and composition of plant vegetation in Tahura R. Soerjo, which were used as a learning resource for biology. This study used a purposive sampling technique. The method used is a combination of paths and checkered lines. The data analysis technique used is the Importance Value Index (INP), the dominance index, the diversity index, the wealth index, and the evenness index. The results showed that the identification of plant vegetation diversity was found as many as 33 species from 17 families that came from 3 divisions. The highest INP was found at the seedling level. The value of the dominance index is less than 1. The results show that the value of the density index is low, because it has a value of <3.5. The evenness value is at a high value, except at the tree level.
