Abstract
The ultrasound frequencies are still receiving a lot of interest by scientists and researchers. It is used in many areas of life, especially medicine, where it was used in the diagnostic and therapeutic side. And also, it is used in the field of industry and other fields of life. The ultrasound frequencies cannot be heard by humans, but most animals hear them, especially dogs. Ultrasonic frequencies cause inconvenience in dogs. In this study, a modified device was made and used to eliminate dogs from cities and neighborhoods. The modification was of some electronic circuits in the available devices (available in the local markets) to generate ultrasound frequencies. The modified device was carried and switched off-on in multiple areas around cities and countryside and applied near groups of dogs in order to see the influence of the switch on (producing ultrasound frequencies) of the device on animals. The use of the new technique results in expel animals and dogs away from the areas of wave centers. Therefore, this technique can be used against predators such as pigs and wolves in rural areas, especially as it has spread widely at present.

Authors: Supriana C E 
Published: April 2021

Abstract
The local government of a city as an organization depends on decision makers in government management to support the vision and mission of the city to achieve eco-city goals based on data and information from several knowledge domains. Knowledge management is seen as an increasingly important scientific discipline that encourages the creation, sharing and utilization of knowledge in an organization. Knowledge management is also related to the concept of intellectual capital, the most valuable organizational resource. Knowledge sharing systems are designed to help decision makers and stakeholders share their knowledge. Most knowledge management systems in organizations are designed to share the explicit knowledge of individuals, organizations and finally distributed to the community. This research is the approach in the development model that can be used in the governance to achieve eco-city goals. Complex knowledge about eco-cities requires policies that are based on current knowledge and can be implemented immediately with a thorough understanding of all aspects. The results of this study are understanding the problem of knowledge sharing as a valuable organizational asset, designing a knowledge sharing systems model, and improving systems to improve the quality of knowledge.

Abstract
The purpose of this research is to understand sponge species, micro symbiont, performance, mechanisms, and types of compounds resulting from biodegradation. The analytical method is applied by selecting the model, results from characterization and morphological identification, phenotype, genotype. Selected of micro symbiont are made as suspensions, interacted with modified naphthalene contaminated waste. The biodegradation process using the Bacillus Sp (BS) isolates sponge Neopetrosia Sp and Acinetobacter Calcoaceticus (AC) isolated from sponge Callyspongia Aerizusa, was carried out by interacting a microscopic suspension of 5,000 mg/L naphthalene waste for 25 days. Micro symbiont biodegradation results by determining the concentration of contaminants and biodegradation products, in the form of pure organic compounds using GC-MS, and the analysis of functional groups of natural components using IR. Destruction of the naphthalene molecule occurs through an enzymatic reaction mechanism, observed based on visible parameters. The performance of BS symbiont biodegradation on naphthalene is in the range of 7.34% - 51.37%, while the AC range is 5.84% -37.26% in w/v, achieved within 5-25 days interaction. Biodegradation products based on functional groups were identified as compounds of aldehyde, ketone, carboxylic acids, esters, alkanes. Observation of biodegradation parameters confirmed pH changes, increased optical density values, gas bubbles formed and the smell of fermentation.

Authors: Yustiani Y M , Pradiko H , Nazarudin M 
Published: April 2021

AbstractThis study aims to develop a phosphate distribution model up to the calibration stage in the Cipicung River. The model was simulated to determine the distribution of phosphates using a volume control approach so that the river is likened to an elongated reactor divided into several segments. Pollutant load entered is considered to be point source so the model does not take into account other loads that enter the river. Based on the results, the deviation or an error made in the calculation of the initial model at a distance of 40 m from the leachate outlet is 1.9%. The error results obtained in the calculation of the initial model are quite large; this is due to several factors that exist in the components of the model. The component model that influences the magnitude of the error is the decay rate (k). In the calibration process the model components that affect the magnitude of the error can be varied to find the best fit for the data in the field. The variations of k value were 10, 13, 15, 17 and 20/day. The closest model to the conditions in the field is using k value of 15/day with an error of 0.013%.

Abstract
Housing parks are one of the shared facilities in planned housing. Its function is to support the quality of life and social sustainability. To create a sustainable housing park needs a pattern of utilization behaviour of its inhabitants. The aim of this study is to identify housing park utilization behaviour based on their level of income. This research is quantitative by using a survey-questionnaire method. Samples are the users of housing parks in the Greater Jakarta area. The unit of analysis is the household from a different level of income. The number of samples was determined using the Lemeshow formula of 96. The results show that the higher income the lower frequency, duration, and intensity of using parks with significant results. There is a contradiction between the provision and the utilization of parks. The better condition of the higher income housing park, the lower of its utilization. For the low-income with a limited area of his unit, they use parks more frequently, long and intensive. The more spacious residential space, the less frequent residents use housing parks because housing facilities are much better in accommodating the various activities of household members. It is necessary to consider the utilization behaviour of the residents in providing housing parks.
Community gardening and the capacity to enrich social bonding in urban neighborhoods
Authors: Sharif S M , Ujang N 
Published: April 2021

Abstract
This paper argues that the selection of the type of urban green spaces to be integrated into urban neighborhoods is critical in addressing these well-being problems. One of the drivers is the urban migration, where people are relocating themselves to new neighborhoods, cities or countries often with the hope of better economic opportunities and social infrastructure, therefore changing the landscape of the new society and the place they reside. It is worrying as these people might not receive enough social support due to their limited social network. It could further escalate to social well-being problems such as individualism and social isolation and could later be manifested mentally or psychologically as loneliness. Community gardens, as part of urban green spaces, offer meaningful social interaction opportunities that often being missed in the context of modern societies and urban lifestyle. Therefore, there is a need to review the effects of community gardening activities as an intervention strategy to strengthen the degree of social bonding to identify its capacity in integrating isolated people back into community life. As a conclusion, urban designers and policymakers are suggested to adopt community gardens as a safe open space in cities to encourage more people-people-places interaction.
