Abstract The rapid development of the city has resulted in the development of development in each city getting more massive with a relatively fast duration of development. This has very significant impacts on the livelihoods of the people. One of the impacts is flooding that occurs due to wrong land use and improper drainage makers. Drainage as a diversion system for excess water is needed to divert water that falls into the road body and tackle inundation that occurs when it rains. This is intended to reduce the risk of accidents due to slipping of tires due to water. The planning of the road surface drainage system in the case of the Budiman Kota Tembilahan road needs important attention in order to avoid flooding or accidents. In this study, an analysis of drainage planning was carried out with a simulation using hecras 4.0 software to simulate the planned drainage conditions on Jalan Budiman, Tembilahan city. After collecting data on the length of the drainage channel on Jalan Budiman, Tembilahan city and Catchment for the residential area on Jalan Budiman, Tembilahan city, as well as rainfall data for the last 10 years, the planned discharge and drainage for the drainage of Jalan Budiman, Tembilahan city are Qrencana = 0,141 m3/dt  dan Qsaluran = 0,264 m3/dt dimana Qs > Qr with a rectangular cross section. Then the calculation simulation can be done using HEC-RAS 4.0 software. The results of the analysis of the drainage planning of Tembilahan city roads state that the planned drainage using hecras simulations based on manual calculations is able to accommodate discharge and no runoff.   Keywords: Hec ras 4.0, discharge  , simulation Abstrak Pesatnya perkembangan kota mengakibatkan perkembangan pembangunan pada tiap – tiap kota semakin masif dengan durasi perkembangan yang relatif cepat. Hal tersebut memiliki dampak – dampak yang sangat signifikan bagi hajat hidup warga. Salah satu dampaknya ialah banjir yg terjadi diakibatkan tata guna lahan yang salah dan pembuat drainase yang tidak tepat. Drainase sebagai sistem pengalih kelebihan air sangat diperlukan untuk mengalihkan air yang jatuh ke badan jalan dan menanggulangi genangan yang terjadi ketika hujan. Hal tersebut dimaksudkan untuk menggurangi resiko kecelakaan karena tergelincirnya ban akibat air. Perencanaan sistem drainase permukaan jalan dalam kasus jalan budiman kota tembilahan perlu mendapat perhatian yang penting guna terhindar dari genangan banjir atau kecelakaan. Pada penelitian ini dilakukan analisis perencanaan drainase dengan simulasi menggunakan software hecras 4.0 guna mensimulasilkan kondisi drainase yang direncanakan pada Jalan Budiman kota Tembilahan. Setelah mengumpulkan data panjang saluran drainase di jalan Budiman kota Tembilahan dan Catchment Area pemukiman di Jalan Budiman kota Tembilahan, serta data curah hujan 10 tahun terakhir diperoleh debit rencana dan debit saluran untuk drainase Jalan Budiman kota Tembilahan adalah Qrencana = 0,141 m3/dt  dan Qsaluran = 0,264 m3/dt dimana Qs > Qr dengan penampang persegi empat. Kemudian dapat dilakukan simulasi perhitungan menggunakan software HEC-RAS 4.0.Hasil dari Analisis perencanaan drainase jalan budiman kota tembilahan menyatakan drainase yang direncanakan dengan menggunakan simulasi hecras yang berdasarkan hitungan manual mampu mengakomodasi debit dan tidak terjadi limpasan.   Kata kunci: Hec Ras 4.0, Debit, simulasi

In July 2009, the city of Fukuoka, Japan experienced a flood disaster along the Hii River, which runs through densely populated, concrete-covered areas of the city. The drainage system was overwhelmed and the river overflowed due to heavy rainfall and rapid runoff. The event led citizens in its watershed to plan and implement comprehensive flood control. The plan aims not only to mitigate floods but also to revitalize the river environment and populated communities in urban areas. This study reports the activities led by the citizens. They organized and carried out civic forums, workshops, and fieldwork to share views as to how the flood disaster was caused, how floods in the watershed should be controlled, and how the river environment should be rehabilitated. This study illuminates how people, including the flood victims and municipal engineers, can change drastically and communicate effectively in the course of discussing and implementing the comprehensive flood control measures.

Rapid urbanization greatly alters land surface vegetation cover and heat distribution, leading to the development of the urban heat island (UHI) effect and seriously affecting the healthy development of cities and the comfort of living. As an indicator of urban health and livability, monitoring the distribution of land surface temperature (LST) and discovering its main impacting factors are receiving increasing attention in the effort to develop cities more sustainably. In this study, we analyzed the spatial distribution patterns of LST of the city of Wuhan, China, from 2013 to 2019. We detected hot and cold poles in four seasons through clustering and outlier analysis (based on Anselin local Moran’s I) of LST. Furthermore, we introduced the geographical detector model to quantify the impact of six physical and socio-economic factors, including the digital elevation model (DEM), index-based built-up index (IBI), modified normalized difference water index (MNDWI), normalized difference vegetation index (NDVI), population, and Gross Domestic Product (GDP) on the LST distribution of Wuhan. Finally, to identify the influence of land cover on temperature, the LST of croplands, woodlands, grasslands, and built-up areas was analyzed. The results showed that low temperatures are mainly distributed over water and woodland areas, followed by grasslands; high temperatures are mainly concentrated over built-up areas. The maximum temperature difference between land covers occurs in spring and summer, while this difference can be ignored in winter. MNDWI, IBI, and NDVI are the key driving factors of the thermal values change in Wuhan, especially of their interaction. We found that the temperature of water area and urban green space (woodlands and grasslands) tends to be 5.4 °C and 2.6 °C lower than that of built-up areas. Our research results can contribute to the urban planning and urban greening of Wuhan and promote the healthy and sustainable development of the city.

The purpose of this study is to identify and describe the impact and behavior of the community on post-disaster economic conditions in the city of Palu and to know the local government's public policies in handling these cases. Using qualitative methods with a case study approach, literature study, and secondary data processing from various social elements. In addition, data collection was carried out by interviewing informants who felt the direct impact of the earthquake, tsunami and liquefaction in Palu, Sigi and Donggala. The results showed that the post-disaster impact felt by the people of Palu City was generally in the "severe" classification. The socio-economic conditions of the people of Palu include several aspects, ranging from the geographical conditions that are in disaster-prone zones, to the extremely poor health conditions after the disaster. The conclusion of this research shows that the escalation of natural disasters in the city of Palu is considered quite large because it consists of three types of disasters, namely the Earthquake, Tsunami and Liquifation in the same time period. Palu City is the capital of the Province as well as the economic and administrative center of Central Sulawesi Province. Damage to warehousing infrastructure coupled with massive looting from unscrupulous people in logistics supply warehouses resulted in goods that were supposed to be distributed both to the city and the district finally unable to be implemented.Tujuan penelitian ini yaitu mengidentifikasi dan mendeskripsikan evaluasi dampak dan perilaku masyarakat terhadap kondisi perekonomian pasca bencana di kota Palu dan mengetahui kebijakan publik pemerintah setempat dalam menangani kasus tersebut. Menggunakan metode kualitatif dengan pendekatan  studi kasus, studi literature, dan pengolahan data sekunder dari berbagai elemen sosial. Selain itu pengambilan data dilakukan dengan cara wawacara kepada narasumber yang merasakan dampak langsung dari bencana gempa,tsunami dan likuifaksi di Palu,Sigi dan Donggala. Hasil penelitian memperlihatkan bahwa dampak pasca bencana yang dirasakan oleh masyarakat Kota Palu secara umum berada pada klasifikasi “berat”. Kondisi sosial ekonomi masyarakat kota Palu meliputi beberapa aspek, mulai dari kondisi geografis yang berada pada zona rawan bencana, kondisi kesehatan sangat memprihatinkan pasca bencana. Kesimpulan penelitain ini menujukkan bahwa eskalasi bencana alam kota Palu dinilai cukup besar karena terdiri dari tiga macam bencana yaitu Gempa Bumi, Tsunami dan Liquifasi dalam kurun waktu sama. Kota Palu merupakan ibukota Provinsi sekaligus sebagai pusat ekonomi dan pemerintahan Provinsi Sulawesi Tengah. Rusaknya infrakstruktur pergudangan ditambah dengan adanya penjarahan yang massiv dari oknum masyarakat pada gudang-gudang suplai logistik mengakibatkan barang yang semestinya didistribusikan baik ke kota ataupun ke kabupaten akhirnya tidak dapat dilaksanakan.

Soil, performing a number of important functions is the geomembrane and affects the flow of most processes in the biosphere. Wherein geochemical processes occurring in the soil play an important role in the fate of contaminants as organic matter while controlling their redistribution in the ecosystem between its various components are generally leads to the formation of stable areas of contamination. The soil not only geochemically components accumulates contaminants, but also acts as a natural buffer that controls the transfer of chemical elements and compounds in the atmosphere. Around industrial enterprises formed geochemical anomalies with high content of pollutants, which can reach a radius of 10-50 km, and the impact of large industrial centers can be traced to a distance of 100 km. All known processes of metal accompanied by the formation of large amounts of waste that pollutes air, water and land surface. Mechanical engineering is an important industry of the Orenburg region and is represented by enterprises of the military-industrial complex, agricultural machinery, machine tools, equipment for ferrous and non-ferrous metals, vehicles, electric household appliances. In the machine-building complex of the Orenburg region includes more than 70 large enterprises. The share of engineering products in the volume of industrial production is about 8%. In this case, the natural environment of the city of Orenburg slabozaschischena from most adverse geo-environmental factors. Based on this, we carried out a study on the quality of soil and environmental situation prevailing in the city of Orenburg, in the zone of influence of the enterprise Plant drilling equipment.

Abstract. A study on water infiltration and solute transport in a clayey vadose zone underlying a dairy farm waste source was conducted to assess the impact of desiccation cracks on subsurface evaporation and salinization. The study is based on five years of continuous measurements of the temporal variation in the vadose zone water-content and on the chemical and isotopic composition of the sediment and pore-water in it. The isotopic composition of water stable isotopes (δ18O and δ2H) in water and sediment samples, from the area where desiccation crack networks prevail, indicated subsurface evaporation down to ∼3.5 m below land surface, and vertical and lateral preferential transport of water, following erratic preferential infiltration events. Chloride (Cl-) concentrations in the vadose zone pore water substantially increased with depth, evidence of deep subsurface evaporation and down flushing of concentrated solutions from the evaporation zones during preferential infiltration events. These observations led to development of a Desiccation-Crack-Induced Salinization (DCIS) conceptual model. DCIS suggests that thermally driven convective air flow in the desiccation cracks induces evaporation and salinization in relatively deep sections of the subsurface. This conceptual model supports previous conceptual models on vadose zone and groundwater salinization in fractured rock in arid environments and extends its validity to clayey soils in semi-arid environments.

<p><em>Laker is a typical Palembang handicraft in the form of all products or household utensils made of wood, rattan, bamboo or whatever is painted with black ink and then coated with varnish as an ingredient to beautify it as well as preservative. In this modern era the use of Crafts Laker in palembang is increasingly fading and it's not longer a culture in the City of palembang, especially the younger generation. The lack of promotion carried out on Laker handicrafts has made many of today's young generations not too familiar with Laker crafts, not even a few of them don’t know at all what laker craft is. Moreover, in the current development era, there is a fear of changing cultural heritage forms as a result of the impact of the development and progress of modern technology and other cultural elements that come from outside. To avoid this, visual promotion efforts are needed to the people of Palembang. This promotion was carried out to be able to invite the people of Palembang to cultivate laker crafts in daily life,especially the younger generation. Therefore the Visual Communication Design, Promotion of Laker Crafts is a form of persuasive effort to the people of Palembang, especially to get to know the Laker Crafts so that they can instill a sense of love and pride in Palembang Laker crafts that are known to the Palembang youth, and can invite Palembang people, especially the younger generation cultivate Laker crafts in daily life along with the trends of the times.</em></p>
