Abstract

Ammonia concentration in raw drinking water at Jakarta varied until 2,0 mg/l, that value has reached out the standard of ammonia (1,5mg/l) according to KepMenkes No 907/MENKES/SK/VII/2002. Ammonia in raw water could react with chlor to be choramine, which have lower disinfecting power. It could make chlor consumption being bigger, beside that presence of THMs and chlorophenol as by product of disinfecting is bigger. This research had done in PDAM Pulo Gadung  from December 2004/ January 2005. The purpose of this research was to know effectively of turbidity, organic matter and ammonia removal in raw drinking water by submerged biofilter using honeycomb tube plastic media and ultrafiltration with hollow fiber membrane processes. The feed water entered into the reactor continuously on aerobic and nonaerobic condition with the varied hydraulic residence time from 5-2 hour then continued with ultrafiltration process. Efficiency of ammonia decreased in nonaerobic condition in bioreactor average between from 41,45 - 70,30% and efficiency in ultrafiltration 34,48 - 38,71%. While in aerobic condition in bioreactor average between 44,04-75,00% and in ultrafiltration 35,00 - 38,89%.

Abstract

In order to execute sustainable agriculture, an agricultural system is required, particularly an effective and efficient irrigation system, to maximize the use of available water while minimizing water waste. For these reasons, a technological approach is required to implement more efficient irrigation and be environmentally friendly. Smart irrigation systems utilizing data-driven techniques such as the Internet of Things (IoT) that minimize the environmental footprint are one of the current technological approaches on the rise. However, studies on this topic's challenges and prospects have been conducted and still need to be completed. This study aims to provide a more thorough understanding of the use of smart irrigation so that it can be more widely adopted. Recent studies on sophisticated irrigation management principles and smart irrigation monitoring are highlighted. Researchers will be able to use this review to identify directions and gaps for upcoming research activities in this area and monitor and develop control prospects associated with irrigation agriculture.
