The city of Surabaya as the center of government and business in East Java has made the city of Surabaya experience rapid property growth in all types including apartment growth. The high growth of apartment units in Surabaya, whether they have been built, are being built, or are planned for construction will be in line with the increasing population growth in the city of Surabaya. This will be accompanied by an increase in the need for drinking/ potable water in the apartment itself. The purchase price of PDAM water specifically for apartments, which is more expensive than the landed house rate, also burdens the apartment residents. Therefore, we need initiatives and efforts to meet the demand for ready-to-drink water for apartments. This study will analyze the technical aspect, financial aspect, and risk analysis of the application of a ready-to-drink water supply system in an apartment so that it can be used as reference material or material for further academic studies. Based on the analysis that has been carried out, the application of a ready-to-drink water supply system in the apartment is declared technically and financially feasible. Risk mitigation related to the application of a ready-to-drink water supply system in apartments is carried out by allocating risk to parties who are relatively able to manage it or because they have the lowest cost to absorb this risk.

The quantity of waste produced continues to increase every year, along with the increase in the population in a region. However, such improvements tend not to be comparable to their management capabilities. Through Jakstrada, 100% management can be achieved by 2025, but requires high community participation in order for the target to be achieved. Yogyakarta has a high growth rate of community-based waste management activities, especially Sleman Regency which until now has had 147 locations, with various forms of activities, such as waste banks, waste alms, TPS 3R and other forms of independent waste management. However, it is recognized that the growth has not been evenly distributed at the sub-district level (kapanewon) and the village (kalurahan). Based on the analysis obtained influence from the role of Independent Waste Management Network (JPSM) Sehati Sleman Regency as the parent organization. So that mapping the location, potentials and challenges is important to do, while restructuring the parent organization in order to provide performance in the process of mentoring, coordination and liaison with various stakeholders.

Surface water is needed as raw water to meet water quality requirements. This study applies a coagulation unit with a hydroulic process, flocculation and sediemntation. The three units are designed in a simple, energy efficient and portable circuit. This unit can be used to treat surface water with portable scale. The discharge of 9 L / minute as an inlet is expected to be sufficient to meet the needs of clean water on a household. PAC and HCA coagulants were used to remove turbidity and suspended solids with various concentrations. The test parameter used to measure the effectiveness of this unit in removing suspended solids is TSS. TSS removal is very significant with the addition of a filtration unit.

This pandemic time has forced us to redefine the meaning of the space. There are many things that make us have to change the way we did in our daily lives. From how to dress, worship, eat at restaurants, queue to buy tickets, meetings, until when we return home after doing activities outside. This paper aims to provide an overview of the current crisis related to spatial experiences by reviewing current issues regarding the impact of the pandemic on architectural aspects and urbanism. Descriptively, interdisciplinary studies related to pandemics are discussed and juxtaposed by looking at several topics of local resilience in the Nusantara. The people of the Nusantara have various ways to survive, but it seems that the pandemic requires us to change our mindset about how architectural and city planning prioritizes health factors and is resilient to current conditions, because this is not the first time and (it seems) will repeat itself. And architecture cannot respond this alone.

A bridge is a connecting facility for an area that functions as a supporting facility for the economy of the region. Bridges have a crucial function in an area to carry out activities and daily work such as trade, social, political and so on. In East Java, the type of truss used mostly uses Warren type trusses, so a comparison analysis with other types of bridges is needed to determine the most efficient type of bridge. In this analysis the Pratt type bridge is used. This analysis aims to compare the ratio of strength to total structure weight. From the output analysis, it is that the Warren type bridge the ratio of the structure is 3,417, while the Pratt type bridge has a ratio of strength to weight of the structure is 3,358. The deflection that occurs in the Warren truss structure is -0.0528 smaller than the Pratt type bridge which is -0.0571. The weight of the Warren type bridge structure weighs 18042.4 kg, while the Pratt type bridge is 19023 kg. Based on the analysis results obtained, it is shown that the ratio of the strength and weight of the Warren type bridge structure is 3,417 and the Pratt type is 3,358.

The agricultural and plantation waste biorefineries are the new strategy of the future to realize sustainability, but most are still in the conceptual stage. Biorefineries will allow communities to convert their agricultural and plantation waste into new value-added renewable energy, biochemical compounds, and fertilizers. Several biorefinery concepts of agricultural and plantation waste have been developed, but few have been commercially realized due to cost constraints and little reliance on new technologies, expected results, and profits, and reliability of operations. Therefore, this publication presented the concept of biorefineries in general, agricultural and plantation waste in Indonesia that has the potential to be used as raw materials for biorefineries and their manufacturing stages, the prospects of the products produced, and the results of the analysis on the challenges that will be faced in further development.

The abundance of microplastics in Surabaya's surface water can disrupt the sustainability of the river ecosystem and have a bad impact on humans. Because most of the raw water used by the people of Surabaya comes from surface water. Microplastics less than 5µm in size contain hazardous chemicals such as Polycroline Binefil (PCB) and are toxic. Microplastics can carry heavy metals and also some pathogenic microorganisms that attach to the microplastic body, this can possibly enter the bloodstream and infect the body. One of the processing alternatives that can be used to reduce microplastic levels is to use electrocoagulation. Electrocoagulation is the process of clumping and depositing fine particles in water using electrical energy. Microplastics contained in water are removed through a process of flocculation and deposition. This study aims to determine the effectiveness of reducing levels of microplastics using electrocoagulation with variations in the distance between electrodes and detention time. The variation of the distance between the electrodes used was 1.5 cm; 2 cm; 3cm; and 5 cm. From the research conducted, it was found that in order to reduce the microplastic levels in surface water samples, the most effective distance between electrodes was 3 cm with a decrease in microplastic levels by 89%.

Along with the development of the batik industry in Indonesia, the number of batik craftsmen is also increasing. However, there are still many batik industries that dispose of their waste directly into the river without being processed first. Batik liquid waste contains organic materials such as COD, BOD, TSS and heavy metals which are dangerous if disposed of directly into the environment. The method used to overcome COD and TSS contamination in batik waste is the electrocoagulation method. The variations used were the electric current (1A, 3A, 5A, 7A, 10A) and the cross-sectional area of the electrode (3x10 cm; 4x10 cm; 5x10 cm; 6x10 cm; 7x10 cm). The results of this study showed that the highest reduction in COD levels was found in the 10 Amper current strength variable with a plate size of 7x10 cm with a COD value of 264.83 Mg / L or 62.12%. Whereas for TSS, the optimum decrease in TSS levels was the 7 ampere current strength variable with a plate size of 7x10 cm, namely 500 mg / L or 86.21%.
