Abstract

Sustainable water resources management system is a water resources management system that is designed and managed and fully contributes to the community (social and economic) for present and in the future, while maintaining the sustainability of its ecological aspects.This research was under taken by direct observation in the field. Then the data obtained from the field is processed using a computer program. This research activity was carried out in Wasile Timur Village, East Halmahera Regency, North Maluku Province. The results of this study indicate that the diameter of the pipe used is diameter 300 mm, 250 mm, 200 mm, 150 mm, 100 mm, and 63 mm. Based on the variation of the pipe, the maximum pressure is 49.37 m or equal to 4.937 bar while the minimum pressure is 26.39 m or equal to 2.639 bar. As for, the pressure from the results of the analysis meets the distribution network planning criteria, namely a maximum of 9.0 - 12.4 bar and a minimum of 0.5 - 1.0 bar. Maximum flow speed of 0.60 m / s and minimum speed of 0.30 m / sec flow velocity. Analysis results is showed the planning criteria which according to the provisions is a maximum of 2.5 m / sec and a minimum of 0.25 m / sec.

Abstract

The research aims to determine the effect of SSK treatment with liquid smoke on the morphology and acoustic properties of SSK reinforced composites. The research method is an experimental method with variations in fiber treatment by soaking in liquid smoke for 1, 2 and 3 hours. Next, after soaking the fiber, it is heated in an oven at 40ºC for 30 minutes, then the resulting fiber morphology is observed using a JEOL JCM 6000 SEM tool then SSK reinforced composites are made for acoustic testing, specimen making is done by preparing resin and long fibers. 1 cm fiber, 60% resin composition and 40% SBP, after drying a composite acoustic test specimen was made. The results show that SSK treatment with liquid smoke increases the fiber morphology to become rough and porous, so that the SSK reinforced composite has a sound absorption coefficient value for the SSK TP composite of 0.1175 db, while the SSK P1J, P2J, and P3J composites have a sound absorption coefficient value of 0.1304, 0.1199, and 0.1181 db. , this shows that the SSK P1J composite is better in sound absorption by 10.92% when compared with SSK TP, so it can be recommended as an environmentally friendly acoustic material.
