Authors: Lathifah A N , Asmara A A , Alfisyahr F A N , Maziya F B 
Published: December 2021

Abstract
Chromium (VI) in the production process, such as textile, tannery, and electroplating industry, produce hazardous waste when disposed of directly into the aquatic environment. Several chromium pollutions cases, not only in water but also in the aquatic organism, occurred in some regions in Indonesia. Various methods can reduce the Chromium (VI) waste. One of them is the biological method by employing such kinds of bacteria. Arthrobacter chlorophenolicus is a pioneer bacterium of Mt. Merapi, which can survive in the minimum conditions of the bacterial primary nutrients, carbon, and nitrogen. This study aims to investigate the ability of A. chlorophenolicus to remove Cr (VI) at various concentrations. The research was carried out by growing the A. chlorophenolicus into two nutrient media conditions, minimal and rich-nutrient media containing different concentrations of Cr (VI) (5, 10, 20 ppm) for eight days. The results showed that the A. chlorophenolicus were grown on both minimal and rich-nutrient media. The A. chlorophenolicus could reduce for about 80% of 10 and 20 ppm chromium in eight days. Our results indicate that A. chlorophenolicus, the pioneer bacteria of Mt. Merapi, has a grand promise for use in Cr (VI) remediation even under minimum nutrients conditions.

This study aims to analyze the influence of cement substitution with aluminum slag ash on the compressive strength and water absorption capacity of the paving block, and the appropriate type of paving block quality which is following SNI 03-0691-1996. The test objects used were paving blocks with a ratio of cement and sand of 1:3, where the composition of the addition of aluminum slag ash used was 5%; 10%; 15%; and 20%. The tests in this study were on compressive strength, water absorption capacity, and Toxicity Characteristic Leaching Procedure (TCLP) tests. The optimum composition is 10% aluminum slag ash in cement substitution. The type of quality is category B paving for parking equipment. The results of the TCLP on a 10% composition paving obtained that the parameter concentration is below the TCLP quality standard.
Application of a hydrological method for determining monthly environmental flow in Code River, Indonesia
Authors: Nugroho Adam Rus 
Published: December 2021

Abstract
The declining groundwater in Yogyakarta could potentially affect the Code River baseflow, thus lowering the river streamflow. Consequently, the riverine ecosystem would suffer from a low quantity of streamflow. The quantity standard of streamflow can be determined by calculating the environmental flow. In this study, the environmental flow requirement (EFR) for the Code River is determined by applying an enhanced version of the most-used hydrological method, namely the Modified Tennant Method based on Multilevel Habitat Conditions III (MTMMHC-III). The EFR in the Code River could be calculated successfully by the MTMMHC-III with a satisfactory temporal variability. The EFRs are the lowest during July to October in the normal years, July to September in the wet years, and July to December in the dry years. The EFRs are highest during January to April in the normal and dry years and January to May in the wet years. However, the EFR might become too low in the dry years, especially from the beginning of the dry season (May) until the early wet season (December), with only 4-11% of the average annual flow. Ultimately, the MTMMHC-III method is a better hydrological method than the original Tennant Method and Q95 method.

Abstract
One of the problems that are faced by the Universitas Islam Indonesia (UII) is the amount of solid waste generated each year, add the increasing number of the student each year, then the problem becomes much worse and difficult to handle. Regarding it, the awareness of each student about solid waste management is needed. The 2 main purpose of this study is first to determine the composition and the generation of solid waste using the samples taken from 10 temporary solid waste dumps (FPSB, D3 Economics, FMIPA, FTI, FIAI, FTSP, FK, Central Library, Kahar Muzakir, GKU, and Rectorate) and the second is to identify student’s perceptions and behavior about individual solid waste management. The research was conducted using qualitative and quantitative descriptive approaches. The results show that the average amount of solid waste generated is 0.017 kg/person/day this is in line with the solid waste management record that shows that on daily basis each person produces approximately 0.010 - 0.020 kg. While the study about the students’ perceptions and behavior towards solid waste management shows that while most of the students are aware of it, the implementation is still lacking.

Abstract
The Special Region of Yogyakarta Government took one step to improve access to proper sanitation for the community through the Communal WWTP. There are four communal WWTP procurement programs in Sleman District: Community-based Sanitation, Urban Sanitation Rural Infrastructure (USRI), Special Allocation Fund and Community-based Environmental Sanitation. After the Communal WWTP was built and operated, various problems indicate the Communal WWTP has not run optimally after construction. Therefore, this study evaluated thirteen Communal WWTPs in Sleman District after construction was carried out. The aspects reviewed in this study were the administrator institutional and the management’s performance using the scoring method. The evaluation results based on the administrator institutional aspect and the management’s performance showed that Ambarketawang WWTP had less performance with a total score of 16. At the same time, other WWTPs got the optimal category with a total score more than equal to 25. These results indicate that the Community-Based Environmental Sanitation procurement program was considered less than optimal because the Ambarketawang WWTP did not keep Communal WWTP documentation and had no maintenance Standard Operational Procedure (SOP). The administrators did not also understand the main tasks and functions as administrators.

Published: December 2021

Abstract
The growth of cities has an impact on society. As a result of the population’s increased bustle and activity needs, dwelling space is becoming increasingly limited. The concept of “third place in hybrid and multicultural areas” is explored in this study, which combines adaptive reuse in buildings with the idea of multicultural hybridity. By adapting historic structures into new purposes that meet current needs, we could solve escaping spaces. To put that concept into practice, we must first comprehend the region’s cultural characteristics. The heritage building in Pasar Baru is situated in an area generated by the complex hybridity of Jakarta’s numerous ethnic communities. This area’s hybridity offers an exciting place that can be used as an escape route. This study employs a qualitative research approach that includes in-depth observations in Pasar Baru. We study old buildings that have a hybrid character from the ethnicities prevalent in Pasar Baru. According to the findings, heritage structures undergoing adaptive reuse must be evaluated regularly to account for changes in spatial conditions that occur over time. Adaptive reuse transforms ancient structures into new roles in conservation and uses a cultural context approach in the surrounding area, allowing for more efficient service.

Published: December 2021

AbstractIn 2018, Palu City was affected by massive disasters (earthquakes, tsunamis, and liquefaction) which paralyzed various activities and resulted in losses of around Rp. 7.6 trillion. The government compiled a disaster-prone zone map (ZRB) that showed 96.03% of Palu City was classified as disaster-prone. It does not only impact the community’s perception of disaster risk, but also on settlement preferences (moving, hesitant to move, and not moving). This condition will affect the community resilience level against disasters. This study aims to determine the correlation between settlement preferences and community resilience, and determine the level of post-disaster community resilience in each sub-district of Palu City. This study’s analysis was done by using SEM-PLS. The variables used are social, economic, environmental, infrastructure, culture, government, and settlement preferences. The results show that all variables have significant impacts. The highest correlation came from the settlement preferences. High community resilience is found in Mantikulore and East Palu sub-districts, moderate community resilience is found in South Palu and West Palu sub-districts, while low community resilience is found in Tawaeli, North Palu, Ulujadi, and Tatanga sub-districts. The results of this study can be used as recommendation for the government to increase community resilience in Palu City.

Published: December 2021

Abstract
In the age of New Space, faces the global problem of orbit space constraint. Sustainable development of space activities will be possible only when space users implement technologies and practices suitable to avoid accumulating objects in orbit. Artificial debris in orbital space has reached catastrophic proportions. This harm the Earth’s ecology leading to increased steps to transform a planet that is unsuitable for life. Based on the fractal analysis, the graphic interpretation of the components of SWOT-analysis of development of the rocket and space industry is built. It is found that the weak side and threat to the activities of the aerospace industry is the insufficient funding of implemented projects and inefficient distribution of finances between its components: science and production. It is proposed to use blockchain technology as an effective tool for the cybersecurity of space objects. The ecological risks from space activities that affect the Earth’s ecology are analyzed. It is proven that the prevention of severe environmental consequences and minimization of the negative impact of the above threats require the introduction of environmental management systems in space activities.
Study of Cananga odorata (Lam.) Hook. f. & Thoms. Flower Development: Morphological Variations in an Urban Environment
Authors: Ramadhani I A M R , Salamah A 
Published: December 2021

AbstractCananga odoratais a native plant in the Indonesian archipelago. The flowers are often used to produce essential oils with many uses and a distinct fragrance. This study aims to observe each stage of theCananga odorataflower development. The flowers were obtained from a home garden in Pasar Minggu, South Jakarta, from November 2020 until January 2021. Further observations of the stamen and pistil developments were conducted usingDino-Lite Edge Digital MicroscopeAM4115 Series. The results show thatCananga odorataflower development can be categorized into bud, display-petal, initial-flowering, full-flowering, end-flowering, and senescence stages. The flowers require 35 days to develop from bud stage to flower senescence. Stamens and pistils also develop primarily during the bud stages and mature after flower anthesis. Flower mutants were also found and may be caused by a mutation in the flower’s homeotic genes. Each different stages of flower development show a different morphological change in the flower perianth and reproductive organs. A discrepancy of flower morphology within each stage, especially those seen during the anthesis stages, might imply a variation in the flower’s internal factors.

Abstract
Diarrhea, typhoid fever and dengue hemorrhagic fever (DHF) are environmentalbased infectious diseases that contribute to the mortality rate of humans. This paper investigates the spatial distribution and the infectious disease epidemic that occurs based on environmental factors. The three primary diseases analyzed were diarrhea, typhoid fever, and dengue hemorrhagic fever. We abstracted data from several sources, including administrative maps, Regional Spatial Planning, BAPPEDA Soppeng Regency, the Central Statistics Agency (BPS), Public Health Centre, RBI Maps, and National DEM. The tool used in this research is a computer equipped with ArcGIS. The analysis documented that the trend of the three primary diseases did not represent a consistent decline in three consecutive years and even increased in certain subdistricts. Spatial data shows that the spread of infectious diseases based on the incidence rate is still dominated at low levels, although medium and high IR categories are also found in several areas in The Soppeng district. This paper proposes information for local government to implement health development planning and programs, particularly preventing and treating infectious diseases in Soppeng District.

Published: December 2021

Abstract
Particulate matter is one of the threatening pollutants harmful to health. Currently, many researchers focus on the problem of PM2.5 concentrations in urban areas. This study aims to estimate the spatial distribution of PM2.5, and identify human behavior on air pollution in Jakarta. The method used were Spline with Tension to build the PM2.5 models, and multiple linear regression models to analyze human behavior on air pollution. The results showed that the annual average of PM2.5 in the last two years tends to be high in western, southern, and eastern parts of Jakarta. In addition, there was a decrease of PM2.5 concentration in 2020 compared to 2019 assumed as a result of Covid-19 Pandemic restrictions. Besides, analysis results showed a significant association between knowledge and attitude aspects on the action aspect. Based on descriptive analysis, people have good knowledge of air pollution and also concern to reduce air pollution. However, the actions for air pollution control are still not maximized which may cause high PM2.5 concentrations in Jakarta. We conclude that to reduce air pollution, the government should focus on the border areas of Jakarta and it can be done by increasing public knowledge and raising awareness for air pollution.
