Development of urban city is commonly followed by steady growth of economic condition, population density, and negative impact of environmental condition. Reduction quality of environmental condition stimulates the occurrence of environmental degradation within society. Low quality of waste water system, management of garbage, limitation of green areas, and low concern of society toward climate change are example of environmental issues that need to be solved by the government as soon as possible. The succession in achieving aims of Millennium Development Goals (MDGs) is continued by Sustainable Development Goals (SDGs) program from 2015 to 2030. SDGs have numerous action plans in achieving its goals for instance Environmental Health Risk Assessment (EHRA) for waste water system in Blitar. Research methods that use in the present study are as follow (i) Field study named Environmental Health Risk Assessment (EHRA), and (ii) data collection, entry data, data cleaning, data processing and data analysis. The present study concludes numerous results achievement for waste water access are follow : very high (180 districts or 72,58 %), high (26 districts or 10.48 %), medium (28 districts or 11,29 %), low (14 districts or 5,65 %). It can be concluded that the achievement for SDGs for waste water system has been achieved. more actively in investments or asset sharing of airports in the region.

Pembangunan gedung bertingkat tinggi permintaan yang hadir semakin banyak dan banyak juga tuntutan akan pekerjaan konstruksi yang lebih cepat, metode yang biasa digunakan dalam proses pelaksanaan bisa disebut metode konvensional menerapkan tahap pelaksanaan berurutan mulai dari lantai 1 hingga lantai tertinggi. Metode Sistem Loncat Lantai memiliki tahapan pelaksanaan yang berbeda dengan metode konvensional, dimana metode loncat lantai akan meloncat 2 lantai keatas. Penggunaan metode seperti ini dapat memberikan ruang kerja yang lebih luas untuk pekerjaan balok di lantai yang sebelumnya sengaja ditinggalkan. Hasil analisis menunjukkan jika menggunakan metode loncat lantai faktor buckling yang didapat dengan membagi axial dan momen ultimate dengan axial dan momen kapasitas kolom didapat nilai < 1 dan tidak akan terjadi tekuk kolom atau buckling dan kelangsingan kolom yang didapat adalah < 40 atau bisa dikategorikan sebagai kolom pendek. Tingkat kecepatan metode loncat lantai lebih cepat dibanding dengan metode konvensional, 21,8% lebih cepat pada pekerjaan pembesian, 14,9% lebih cepat pada pekerjaan bekisting, dan 21,2% lebih cepat pada pekerjaan pengecoran.

Purpose: Good and coordinated administration is essential for completing a property. This study focuses on aligning individuals' control with their distinct objectives. Homebuilders strive to address problems as effectively as possible to attain the most significant success from multiple perspectives. Design/methodology/approach: SCOPUS.COM is a library of source-neutral abstracts and citations vetted by recognized experts in their respective disciplines. From 1985 to 2022, researchers discovered 835 documents on sustainable housing in the SCOPUS.COM database, according to (1) country or region, (2) source, (3) funding sponsor, (4) subject, and (5) affiliation. Findings: Indonesia ranks below Malaysia, India, and China in Asia and ASEAN but above Singapore and Thailand. Indonesia continues to be competitive in housing research and publication. Sustainability Switzerland has 54 documents, followed by the IOP Conference Series Earth and Environmental Science with 37, International Journal of Housing Science and Its Applications with 24, IOP Conference Series Material Science and Engineering with 19, Habitat International with 13, and Building and Environment with ten documents. Hong Kong, China, Korea, and Malaysia provide the most institutional funding, where the sources include DIKTI, ITS Surabaya, UNDIP Semarang, and U.I. Jakarta in Indonesia. Engineering has 386 documents, Social Science 334, Environmental Science 257, and Energy 161. The Netherlands, Malaysia, Hong Kong, and India account for most affiliations, while three documents from ITS Surabaya represent Indonesia. There are significant gaps in sustainable housing research and publishing. Supporting renewable energy is a global trend, and sustainable development must expand. Originality/value: This paper is original Paper type: Research paper

Indonesian government through National Medium Development Term Plan (2015-2019) aims 100% easy access of clean and fresh drink water, and 100% decent access of sanitation. The present study aims to determine index risk of sanitation modeling (IRS) of domestic waste water as an effort in achieving the target of Universal Access 2020. Discriminants that resulted from the present study are: Z1 = -41.86 - (1,16*IRS) + (0,07*PM) + (0,16*PP) + (0,11*PWM) dan Z2 = 6.74 + (1,54*IRS) + (0,01*PM) + (0,21*PP) - (0,26*PWM) in which it is used to determine domestic waste water system. Variables that influence this system are index risk of sanitation (IRS), female participant (PP), poor people (PWM), and beneficiary (PM). When the equation mentioned above is applied into 154 districts in Surabaya, the result will be as follow: 1) Based on Domestic Waste Water System there are 57 districts (37,01%) that can be included into communal system, 31 (20,13%) districts are included into domestic IPAL system and 66 districts (42,86%) are included into combination between communal and IPAL system.

The commercial development of the area in Sugihwaras Village, Sidoarjo has caused a large discharge runoff that can cause inundation in the area due to land conversion that reduces open land for water absorption. So it needs an increase in drainage capacity by knowing the flood plan discharge for a 5 year return period. Rainfall data taken for observations are rain stations Sidoarjo, Putat, Cepiples and Kludan. The method used to find a 5-year return period is the Log Pearson Type III because it is in accordance with the distribution test with a 5-year return period of 81,171 m³ / sec. With an extensive commercial development area of ± 40,191 m² the planned flood discharge obtained by a practical rational method is 0.630 m³ / sec and can be accommodated with planned drainage and bozem channels with a capacity of 1666.95 m³.
