Abstract
The golden triangle area marked Jakarta city as a business center. Many people interested in land and buildings in this area with one of the reasons by having a strategic location, with no exception for office spaces and buildings. Kuningan, South Jakarta is a Central Business District, which in fact is filled with skyscrapers which mostly uses reflective materials for it’s skin, makes the radiation reflected and increases the temperature in the air and also inside the building. One of few strategies that is effective to prevent heat from radiation is to use exterior sun shading. The method used in this paper is quantitative approach from the simulation results using software to obtain the solar radiation values to determine the ideal sun shading types to be used in the East and West side of the building. The result of this research is the eggcrate and horizontal louvers are the ideal types of exterior sun shading to be used in the East and West side of the building in Kuningan, South Jakarta.
Space and Cultural Behaviour : Deconstruction of Stage ideas in Batak Tribal Traditional Houses
Authors: Bobby Saragih JF 
Published: August 2021

Abstract
In Batak tribal community the idea of dwelling permanently is influenced by labour, social, culture and religion. Territorial behaviour can be seen clearly patterned from the Batak community dwelling, each settlement unit, calls it Huta, attended by clan. Previous researchers believed that the presence of a stage in some traditional houses was more due to symbolic meanings or cosmological ideas. A traditional Batak Toba house represents cosmological ideas of their inhabitants. The space for animals in the substructure symbolizes the underworld. The living area that is raised on stilts is the people’s place that represents the middle world. (Hanan, et all 2015). The behaviour of the Batak culture seems to be the main reason for the presence of the stage in traditional Batak house. Research with an ethnographic approach shows that phenomena to meet socio-cultural needs must be adopted in the spatial arrangement of dwellings. In traditional Batak House, the stage in the house is a strategy to fulfil socio-cultural behaviour in community life. In the Batak culture, a clan is representative of a power, self-esteem is important. The presence of a stage where the buffalo is placed is provided in every house design. The idea of stage in the traditional Batak traditional house is a production space.

The Prospect of Implementing Circular Economy of Solid Waste in Small Islands: A Case Study of Karimunjawa Islands District, Central Java-Indonesia
Authors: Argo Teti A , Rachmawati Yulida 
Published: August 2021

Abstract
Circular Economy (CE) is increasingly used waste management concept especially in transition nations to transforms linear into a circular concept of waste production. CE sees waste as secondary raw material for re-production. Globally, CE has been studied and practiced in recent years. However, there are still few studies related to small islands. The characteristics of solid waste in small islands differ from the one on the Main Island, such as how solid wastes generated and the typology of solid waste. Karimunjawa Islands District is one of the small islands in Indonesia that has begun to experience environmental problems because of the excessive amount of solid waste. This study aims to identify the implementation of CE in small islands. This study was conducted by literature study, questionnaire, observation, interview with local stakeholders, and forum group discussion. The result revealed that there are leaks in macroeconomic aspects from manufacturing activities to consumption activities as well as market failures from consumption activities to waste disposal. It is indicated that waste management in small islands can be sustainable and independent after closing loops/leaks by procuring technology, setting clear regulations related to solid waste management, performing effective waste transportation, and holding house-to-house socialization regarding sustainable behavior.

Abstract
Small island regions are facing disaster risks due to their exposure to various hazards, e.g. floods, landslide, and earthquake. In order to achieve long-term disaster resilience, one of the significant strategies is applying spatial planning based on disaster risk reduction. Methods for multi-hazard risk assessment and risk analysis have been broadly discussed, nevertheless, its implementation in spatial planning is inadequate. In this study, we conducted a multi-hazard risk mapping of Sangihe Island and reviewed its spatial plan. It is identified that disaster risk analysis hardly meets its standard in consequence of insufficient secondary data availability. Also, the spatial plan merely utilizes hazard maps for consideration, not yet as risk analysis, resulting in allocating vital elements in high-risk areas. Hence, secondary data support is necessary for accordance with the needs of standardized risk analysis and is updated regularly. Furthermore, integration of risk analysis into spatial planning is required to determine the direction of development, which not only reduces exposure to hazards but emphasizes more towards the capacity building to reduce vulnerability.

Published: August 2021

Abstract
Morokrembangan bozem is one of the largest bozem in Surabaya with an area of ± 78.69 Ha which is designated as a flood controller in the city of Surabaya. However, the condition of Morokrembangan bozem experienced a decrease in water quality due to the inclusion of pollutant loads originating from waste discharges carried by the drainage channels entering Bozem Morokrembangan. The research can be useful for Surabaya Government to return the function of Morokrembangan bozem. The results showed that the water quality status of Morokrembangan bozem was moderately polluted with the highest pollution load coming from Kali Purwodadi with COD concentration of 28,283 mg / L, BOD5 7,491 mg / L, Ammonia 6,18 mg / L, and Total Phosphate concentration of 6.18 mg / L. The total pollution load that enters the Bozem comes from settlements averaging 99.87 Tons/year and industry averages 0.0028 Ton/year with a total waste load based on sub-dynamic simulation models an average of 26,923 Tons/year. Management efforts can be carried out using an optimistic scenario by building a communal WWTP in the Krembangan District that does not yet have a WWTP and implementing a 3R program to reduce solid waste (garbage), make efforts to manage environmentally friendly land, and increasing community participation.

Abstract
The study determined the composition, abundance, and distribution of phytoplankton in Lake Mainit. Plankton samples were collected in eight sampling stations four times in 2018. A total of 26 phytoplankton taxa in four groups – Bacillariophyceae/Myxophyceae, Chlorophyceae, Cyanophyceae and Euglenophyceae were identified. Aulacoseira was ranked as the most abundant taxa, followed by Zygnema, Fragilaria, Trichodesmium, and Ulothrix. ANOVA revealed no significant (P < 0.05) difference in the number of phytoplankton between the eight stations during the first sampling. In the second sampling, Bunga showed a significantly (P < 0.05) lower number of phytoplankton than the other stations. The third sampling also showed no significant (P < 0.05) difference in the number of phytoplankton between stations. During the fourth sampling, Tagbuyawan had by far (P < 0.05) the highest number of phytoplankton. Species diversity (H’) of phytoplankton was stable at Magticao, Jaliobong, Dinarawan, Kalinawan, and Bunga. The dominance of some species (Aulacoseira, Fragilaria, and Zygnema) affected the diversity and distribution of plankton. Spectrophotometric readings recorded an average Chl-a of 0.75 µg/L. The lake was still considered oligotrophic. Remediation measures and further studies on the lake towards the primary variation of plankton are recommended. Management efforts should be strengthened to support the sustainability of life in the lake.

Published: August 2021

AbstractThis work evaluates the ability to degrade Enrofloxacin (ENR) in synthetic high concentration wastewater by the photocatalytic method using pure TiO2nanomaterials. The material properties, including morphology, crystalline structure, UV-Vis absorption, and surface acidity-basicity, were also characterized. The treatment efficiency of 50 mgENR/L reached over 80% after 2 h of UVA irradiation, at pH 6 and 1 gP25/L. The antibacterial level of ENR after treatment was checked byBacillus subtilisactivity. After treatment, the activity of ENR residue was no longer sufficient to cause inhibition of the bacteria while the degraded product was not toxic to it. The research results show that the photocatalysis material has a good ability to degrade ENR as well as other antibiotic residues in the water environment.

Published: August 2021

Abstract
The presence of scallop shells, one of the marine products, increases the problem of solid waste disposal. This material is disposed to landfill without proper use, making it necessary to develop natural coagulant made from scallop shells. This research aimed to investigate the ability of scallop shells as a natural coagulant to remove turbidity. The scallop shell was used to produce chitosan, then adopted as a natural coagulant compared to a commercial product. Water turbidity, river water, and batik wastewater were examined using different coagulant doses, solution pH, and turbidity concentration. Based on data from this study, scallop shell-based chitosan has a high ability to reduce turbidity concentration in water. To remove artificial turbidity in water (14 NTU), the optimum coagulant dose was 150 mg/L and solution pH was 6. The ability of natural coagulants to remove river water turbidity (81 NTU) and batik was 72% and 87% respectively. The performance of commercial coagulant to remove artificial turbidity, river water, and batik wastewater was similar to the natural coagulant, making this novel natural coagulant a promising coagulant for water and wastewater treatment in the near future. Furthermore, massive production of natural coagulant can also solve the problem of scallop shell solid waste generation.

Published: August 2021

Abstract
This paper investigates the suitability of sewage source gas engine heat pump (SSGEHP) as a retrofit application for a public shower facility. The system performance is evaluated by primary energy ratio (PER) based on a practical example. The performance analysis indicates that the PER of SSGEHP varied in the range of 1.4 to 1.9, showing good potential in primary energy saving (as high as 69%) and emissions reduction compared to gas boiler system. It only needs 1.6 years to recover the initial investment by using the SSGEHP water heating system to reform existing the gas boiler. Therefore, the SSGEHP may be a promising retrofit scheme for the existing gas boilers.

Exploring the causes and repair measures of early cracks in prefabricated bridges
Authors: Suqin Han 
Published: August 2021

Abstract
The study aims to explore the causes of early cracks in prefabricated bridges and propose repair measures. The stude designs a test first. Analysis of the mix proportion and uneven shrinkage of concrete shows that, in concrete, the ratio of air content to water-binder is a quadratic parabola, the fly ash and water binder ratio have a linear relationship, and slurry collection ratio and the water-binder ratio is inversely proportional. The test results suggest that the cracks of bridges are caused by the decrease of relative humidity in concrete. Afterward, some corresponding repair measures are put forward to safeguard the prefabricated bridges.
