The water crisis is identified as the most serious global risk for the coming decade. Distilled water is one of the on-demand elements in academic laboratories; however, water scarcity may eventually affect the education sector, necessitating the implementation of new policies. Human behavior, awareness, knowledge, and opinion is having an impact on water management; accordingly, a questionnaire was purposely designed and validated to assess these variables in a Malaysian public university regarding the use of non-distilled water produced by the distillation process. An exploratory factor analysis yielded four factors: “concept of green laboratory and water”, “usage of non-distilled water”, “knowledge about water distillation”, and “behavior related to water conservation”. Using the Mann–Whitney U test to compare laboratory and non-laboratory users’ responses, the variables “Knowledge”, “Behavior”, and “Opinion” revealed statistically significant differences, with laboratory users scoring higher in all four variables. Employing the Kruskal–Wallis H test in an occupation-based comparison among laboratory users, and with an additional variable “Practice”, showed that “Lecturer” has the highest mean rank for “Awareness”, “Behavior”, and “Opinion”, while “Laboratory Assistant” has the highest mean rank for “Knowledge”. This study provides a rationale analysis for future insights to educate faculty members about the reuse of non-distilled water sustainably.

The San Pedro River has been impacted by continued growth of Fort Huachuca Military Base. The San Pedro River, a riparian-migratory area, has had continuous water flow but now has intermittent water flow. The cause is cones of depression in the aquifer due to domestic well pumping. The aquifer is recharge with water from the river. Cooperative Extension has implemented Resource Conservation Audits for landowners in the lower San Pedro Valley. Also, outdoor classrooms are being constructed at three schools to educate children and community members. The goal of these programs is to educate landowners on water conservation through the use of native and adapted drought-tolerant plants, xeriscaping, irrigation efficiency, water harvesting, soil erosion, and composting. Site visits help landowners identify opportunities to reduce water use. Research-based informational brochures have been produced so landowners can plan and implement water-saving techniques on their properties. This program has been implemented using six members of the Border Volunteer Corp., part of Americorp program.

The sustainability of watershed ecosystem functions in managing the water system can be achieved if the utilization pattern of their territories in accordance with the rules of conservation. A decrease in quantity and quality of the river water can be an indicator that condition of the watershed have been damaged. The destruction of the watershed ecosystem as a result of various causes will be able to threaten supply of sustainable water resources. The aim of this research is to determine and analyze the perceptions and behavior of upstream communities and governments about the function and role of water conservation and watershed in their behavior in the preservation of the watershed and its relationship with the current condition of the Ayung river. The study was conducted in the area upstream of Ayung river, which is in the Belok Sidan and Plaga Village, Petang, Badung, stake holder water users Ayung River such as PDAM, AMDK, rafting and farmers, as well as the government of Badung Regency that responsible for the management and conservation of Ayung River. Results of the study found that the public perception of the functions and benefits of watershed in the conservation of water resources classified in the category of high, but was followed by actions or attitudes in the medium category. There was no real relationship between perception and action, but the action affect current watershed conditions. The role and participation of stakeholders Ayung River water users were still relatively low in the preservation of the watershed, while the government's role classified as medium has not been done in an integrated among sectors and regions. From the results of this study it is recommended that the preservation of the Ayung river through various conservation action were integrated by involving communities upstream more active through the empowerment of local knowledge and improve their welfare. Government plays an important role in moving towards unity of this act.

Abstract. Site-specific variable-rate irrigation (VRI) systems can be used to spatially manage irrigation within sub-field-sized zones and optimize spatial water use efficiency. The goal of the research is to provide farmers and consultants a tool to evaluate the potential benefits of implementing VRI. The specific objective of this research is to evaluate the potential water savings using VRI management compared with uniform irrigation management to maintain soil water holding capacity above 50% depletion using two irrigation scenarios: 1) a standard 12.5 mm irrigation per application; and 2) an application to refill the soil profile to field capacity. A 21-year simulation study was carried out on a selected field with varying degrees of soil and topographic variability. The simulated field had 12 soil mapping units with water holding capacities in the top 0.30-m ranging from 42 to 70 mm. The 21-year simulation covering all weather conditions for each soil produced only two significantly different irrigation management zones for scenario 1, and for scenario 2 only one management zone. However, when the 21-year period was divided into periods with different ratios of rainfall to reference evapotranspiration, the simulations identified 1 to 5 management zones with significantly different irrigation requirements. These results indicate that variable rate irrigation system design and management should not be solely based on long term average weather conditions. Years with differing weather conditions should be used for potentially identifying management zones for VRI systems. Irrigation application depths between management zones ranged from 17 to 38 mm. However, when the actual soil areas of the study field were utilized to calculate the total volume of irrigation water applied, it resulted in an increase in water usage in the 2 and 4 management zones ranging from -1.2% to 5.8%. Water usage with VRI over uniform irrigation was greater by -1.6% to 6.8% in the 12.5 mm irrigations and by -1.2% to 2.2% for the field capacity irrigations Keywords: Management zones, Precision farming, Variable-rate irrigation, Water conservation.

Campus Building

Telkom University makes efforts in developing higher education facilities and capacities by constructing new campus buildings. One of the supports for improving services is sanitation infrastructure in the form of installations consisting of clean water installations, wastewater installations and ventilation, and rainwater installations with the concept of installed clean water. Each building that will be built in the area of West Java Province applies the concept of green buildings and conservation air as regulated in the Regional Regulation of West Java Province 13 of 2013 concerning Buildings, including campus building builders so that business actors are required to implement water management which aims to maintain quality, quantity, and continuity of clean water in West Java Province. The implementation of the installation with the concept of green buildings and air conservation is carried out at the Telkom University Landmark Tower building, which aims to use clean water in the building which can be more efficient because the location of the building is in a clean water distress zone based on the basin map of West Bandung Regency. The implementation of water conservation that is planned is WAC-3 waste water recycling (water recycling) which can be used as a rinse and watering the garden. Construction of infiltration wells which functions to reduce rainwater runoff and increase groundwater reserves, WAC-5 rainwater storage (rainwater storage) which can be used as alternative raw water. The use of the WAC-2 water-saving sanitary device (water feature) uses water usage and PDAM water costs. The application of air conservation that ignores water is 17.5% in the dry season and 61.5% in the rainy season of the clean water need total.
