The selection of tree species planted for aesthetic functions may vary based on their physical appearance and it is very important to use the species of the native trees for ecological purposes. The objectives of this research were to assess the ecological distribution and the aesthetical performance of the collections of the Javanese native trees at the Bogor Botanical Garden. The data were processed and analysed based on habitat distribution and morphological characteristics. Furthermore, the Key Performance Index Assessment Technique was used to give value to each criterion. The stages of tree aesthetic quality assessment were done by simulation using the method of Scenic Beauty Estimation (SBE). Total 469 species of the Javanese native trees were discovered. Based on the habitat distribution, the highest number describes the species of tree scattered throughout the Island of Java (237 species), Western Java (131 species), West and Central Java (53 species), Central Java (17 species), central and eastern Java (12 species), eastern Java (9 species), and western and eastern Java (7 species). Furthermore, the species of native trees also had a range of habitat altitude ranging from coastal (0 masl) to mountain (3100 masl). Then, based on the criteria of aesthetic assessment, they were categorized as good (43 species), medium (172 species) and bad (14 species).

To improve the environmental quality and to increase citizens' index of happiness, Bandung City government has built or either rebuilt and revitalized some urban green open spaces, or in popular are known as public park. Until now the government has built hundreds of parks scattered throughout the city of Bandung, ranging from neighbourhood park to city parks. With the availability of many public parks in Bandung, this attract the citizens' attention, both Bandung's citizen and surrounding citizen, to having activities at public park as an alternative destination. Based on the current conditions, the development of green open space in Bandung more likely to focus on meet user's satisfaction and put aside the fulfilment of other function (ecological, health, socio cultural, economy, and aesthetic) as part of the efforts to increase Bandung city urban green open space sustainability. Since the development of green open spaces only expected to accommodate more visitors, this will result in expanding pavement area which potentially reducing the park's ability to absorb water and reducing existing vegetation. In order to prove that, it is necessary to evaluate the performance of urban green open spaces in Bandung. The evaluation's aims to value the balance between its aesthetical and social function, with its ecological function. This paper will propose a set of indicators which can be used as a tool to evaluate performance of urban green open space as an effort to increase Bandung city urban green open space sustainability. These indicators were obtained through in-depth research and review of some related literatures, sub indicators which obtained at that stage will combined and modified to appropriate with the Bandung City urban green open space characteristics. There are four main evaluation indicator categories, which are ecology, socio-cultural, health, and economy indicator. These categories of indicator would be developed into sustainable urban landscape sub-indi

Prunus species play an important role in preserving the Nepal's unique identity;such as three endemic species of Prunus, Prunus topkegolensis, Prunus jajarkotensis, and Prunus taplejungnica, represent the country's local area. An ecological and social survey of P. topkegolensis and P. taplejungnica was conducted. To analyze these species' regeneration status and population structures, the density of seedlings, saplings, and adult trees were compared, and created a diameter size class diagram. The Wilcoxon signed-rank test was used to compare the average values of seedlings, saplings, and adult trees between two species. To determine the ethnobotanical importance of a species, the relative frequency of citation (RFC) was calculated for various use categories. We classified both species as trees as the average diameter at breast height (DBH) of P. topkegolensis was 19.55 ± 14.66 cm with an average height 5.05 ± 2.28 m, while that of P. taplejungnica was 14.5 ± 7.93 cm with an average height of 4.89 ± 1.66 m. P. topkegolensis had an average 32 ± 31 adult trees, 16 ± 15 saplings, and 21 ± 18 seedlings per 0.1 ha, while P. taplejungnica had 12 ± 5 adult trees, 2 saplings, and 6 ± 4 seedlings per 0.1 ha. The number of seedlings and saplings at the plot level differed significantly between species (W = 75.5, p- = 0.05, and W = 84, p = 0.01, respectively). Both had humped-shaped diameter at breast height size class distribution. However, P. taplejungnica had a more apparent hump-shaped diameter at breast height distribution than P. topkegolensis, indicating that P. taplejungnica has more unsustainable regeneration issues. P. taplejungnica was locally recognized as a separate species from P. rufa, whereas P. topkegolensis was not. P. topkegolensis have seven different use categories, with wood and fuel wood being the most frequently cited, with RFC value 1. Rapid vulnerability assessment (RVA) showed both species are having high conservation threats. In situ conservation mea

Human-wildlife conflict has been one of the most trouble-causing issues in many areas of Nepal including Eastern Nepal. This study assessed the human-wildlife conflict status in Paschim Kusaha Village of Koshi Tappu Wildlife Reserve(KTWR), Sunsari District, Nepal. Data were collected from 47 respondents of different households through questionnaire surveys and formal and informal interviews. Results revealed that the most destructive wild animals were wild elephants, wild boar,and wild water buffalo and the most raided crops were paddy(63.83 %), maize(19.15%), and potato(17.02%). Most of the encounters between humans and wildlife were recorded at night(after dusk and before dawn)(78.72%). Local people were suffering from damage of physical properties, human harassment or nuisance, and depredation of cropland due to wild animals.A total of 70% of respondents had a positive attitude towards conservation despite disturbing human mortality records(22deaths in the last five years) from the reserve area and surrounding. Awareness of wildlife behavior together with conservation and easy access to compensation schemes were suggested to minimize conflicts in the area.

Background Medicinal plants are the fundamental unit of traditional medicine system in Nepal. Nepalese people are rich in traditional medicine especially in folk medicine (ethnomedicine), and this system is gaining much attention after 1995. The use of medicinal plants has increased during the COVID-19 pandemic as a private behavior (not under the control of government). A lot of misinterpretations of the use of medicinal plants to treat or prevent COVID-19 have been spreading throughout Nepal which need to be managed proactively. In this context, a research was needed to document medicinal plants used, their priority of use in society, their cultivation status, and the source of information people follow to use them. This study aimed to document the present status of medicinal plant use and make important suggestion to the concerned authorities. Methods This study used a web-based survey to collect primary data related to medicinal plants used during COVID-19. A total of 774 respondents took part in the survey. The study calculated the relative frequencies of citation (RFC) for the recorded medicinal plants. The relationship between plants recorded and different covariates (age, gender education, occupation, living place, and treatment methods) was assessed using Kruskal-Wallis test and Wilcoxon test. The relationship between the information sources people follow and the respondent characteristics was assessed using chi-square test. Results The study found that the use of medicinal plants has increased during COVID-19 and most of the respondents recommended medicinal plants to prevent COVID-19. This study recorded a total of 60 plants belonging to 36 families. The leaves of the plants were the most frequently used. The Zingiber officinale was the most cited species with the frequency of citation 0.398. Most of the people (45.61%) were getting medicinal plants from their home garden. The medicinal plants recorded were significantly associated with the education leve

Dengue hemorrhagic fever (DHF) has become an endemic in major cities in Indonesia. The climate change and poor level of awareness and knowledge of the community in Indonesia have caused an increase in the DHF cases. Outbreaks on January until April 2015, the morbidity rate reached 50.75. In 1996, the Intergovernmental Panel on Climate Change (IPCC) predicted threefold increase in the dengue hemorrhagic fever incidents in Indonesia by 2070, if the environment and community conditions do not improve. This study aims to provide a dynamic model to predict the dynamics of the DHF incidents based on climate variability in the Special Capital Region of Jakarta. The design of this study was ecologic study with hypothesis test, modelling, simulation, and intervention. In collecting the data, interview with respondents and measurement of climate variables were conducted. Interviews with respondents include the level of knowledge, attitudes, and behaviour (PSP) of the community. Measurements of climate factors include rainfall, temperature, humidity and CO2 level in the ambient environment. The DHF system dynamics model simulation shows that the significant effect on the decline of Breeding Places and the decrease of DHF cases were achieved by increasing the participation of the community to actively control water places that are potential for mosquito breeding places.

Bamboo or tiying (Balinese language) is a widely used non-timber plant in Indonesia especially in Bali. The presence of bamboo appertains to its ethno-botanical function of bamboo especially for rituals. However, there are other utilization of bamboo which is naturally grown or intentionally planted. Kedewatan as a famous place in northern Ubud, Bali have many lavish hotels with its natural environment and appealing place. The aims of this study is to invent bamboo species diversity and bamboo utilization on private areas of hotel in Kedewatan. Methods used in this study was field survey with observation and interview technic. Observation was implemented by purposive sampling methods by selecting hotel which adjacent to Ayung and Wos rivers. Interview was conducted with some key persons in charge on managing hotel garden. In addition, bamboo species identification was established through literature study. The results show that there are eleven bamboo species found on the survey area with most commonly employed species in the area were tiying tali (Gigantochloa apus (J.A. & J.H. Schultes) Kurz.) and tiying gading (Phyllostachys sulphurea (Carr.) A. e.t. C. Riv.) which were belong to exotic species. The areas which bamboo cultivated were welcome area as a hedgerow and near hotel lobby, between, outside and inside villa buildings, and naturally grown in the riverbanks with a good landscaping arrangement. Bamboo plantations were utilized to adorn and support the quality of the hotel building as well as to conserve soil and water along Ayung and Wos river canyons. The other utilization of bamboo was to facilitate ritual activity in Kedewatan village. They are allowed to ask for limited amount of bamboo culms with condition not to damage the physical appearance and function that desired by the hotel manager or hotel owner.

Not only at the water treatment process, disinfection is required for the inactivation of pathogen microorganisms in wastewater treatment before it is released to the waterbodies or for recycling purposes. During the disinfection process by chlorination, it found the formation of harmful disinfection by-products (DBPs). DBPs formed because of the reaction of inorganic and organic matter as precursors with chlorine/chloramine. The aim of this research is to analyze the potential formation of Carbonaceous Disinfection By-products (C-DBPs) as the most DBPs in the water and Nitrogenous Disinfection By-products (N-DBPs) as the most DBPs of the wastewater. Most DBPs have precursors from natural organic matter (NOM) and the effluent of sewage treatment contributes to increasing the DBPs precursor. The review method start with identifying DBPs precursor, potential formation of DBPs, factor affecting the formation DBPs, and finding the advanced technologies that are appropriate to remove DBPs and their precursors. It found that trihalomethanes (THMs) is the most widely found in water treatment such as chloroform, bromodichloromethane, and bromoform. N-nitrosodimethylamine (NDMA) is one of N-DBPs that most presence in polluted water and also haloacetonitriles (HANs), haloacetamides (HAcAms), Nitrosoamine (NAs), cyanogen halides (CNX), halonitromethanes (HNMs), N-nitrosomethylethylamine (NMEA). The result shows that disinfection plays a role of formation DBPs in water and wastewater treatment. DBPs have potential health risks for the human body because they are genotoxic and carcinogenic. Physicochemical treatment can remove the precursor of DBPs and advanced treatment enhances the removal of DBPs.
