Efficient Use of Water under Irrigation Management Practices for Surface Irrigated Rice

With the continuous climate change we are experiencing; extreme heat, drought, and declining water supplies that affect our rain fed and irrigation systems resulting to a higher demand for water for evaporation and evapotranspiration by crops which lead to more frequent soil moisture deficit which is unavoidable and there are still other factors that contributes to water head loss. This make it necessary to find out novel ways to resolve the issues regarding irrigation management. Though there are many existing innovative water management ideas available out there, but it takes to shed huge amounts of government funds to implement. This study consists of designing a water-recycle model to efficiently use the limited water supply and further attain to serve the total surface area of irrigated rice. The proposed design uses a renewable energy that pumps out water from the catch basin back to its water source, this method entirety use the most out of the water supply to lessen water wastage and water shortage and to maximize water saving in the area.

INTELLIGENT AQUAPONICS USING IoT

Conventional agriculture and aquaculture present the unwelcome situation of great extents of consumption in both land and water resources. The threat of pollution of water bodies also need to be taken into account. The urbanization policies and population explosion with rapid migration from rural areas makes the concept of aquaponics reuse of ecological crop rising and reusing methods essential. This technology coalesces recirculation of water used in aquaculture and hydroponics for crop supplement and water recycle; reduction of pollution and enhancement of efficiency and yield. Hydroponics and aquaculture is proposed in this paper on a combinatory solution for better agriculture practice. Intelligent monitoring of water quality and nutrient circulation can be abstracted, tabulated and summarized. This paper popularizes the implementation of IoT in aquaponics.

Hybrid System Coupling Moving Bed Bioreactor with UV/O3 Oxidation and Membrane Separation Units for Treatment of Industrial Laundry Wastewater

This paper describes the investigations on the possibilities of treatment of wastewater generated in an industrial laundry with application of a combined biological-photooxidation- membrane system aimed at water recycle and reuse. The two treatment schemes were compared: 1) scheme A consisting of a treatment in a moving bed biological reactor (MBBR) followed by microfiltration (MF) and nanofiltration (NF), and 2) scheme B comprising MBBR followed by oxidation by photolysis enhanced with in situ generated O3 (UV/O3) after which MF and NF were applied. The removal efficiency in MBBR reached 95–97% for the biochemical oxygen demand; 90–93% for the chemical oxygen demand and 89–99% for an anionic and a nonionic surfactants. The application of UV/O3 system allowed to decrease the content of the total organic carbon by 68% after 36 h of operation with a mineralization rate of 0.36 mg/L·h. Due to UV/O3 pretreatment, a significant mitigation of membrane fouling in the case of both MF and NF processes was achieved. The MF permeate flux in the system B was over two times higher compared to that in the system A. Based on the obtained results it was concluded that the laundry wastewater pretreated in the MBBR-UV/O3-MF-NF system could be recycled to any stage of the laundry process.

Bioenergy for a Cleaner Future: A Case Study of Sustainable Biogas Supply Chain in the Malaysian Energy Sector

A life cycle assessment (LCA)-based environmental sustainability evaluation conceptual framework of biogas production has been proposed to improve the sustainability of biogas supply chains. The conceptual framework developed in this study can be used as a guideline for the related stakeholders and decision makers to improve the quality and enhance the sustainability of biogas production in Malaysia as well as promoting biogas as a clean, reliable and secure energy. A case study on an LCA analysis of a zero waste discharge treatment process has been conducted. In the zero discharge treatment system, biogas can be produced with a maximum water recycle and reuse. It was indicated that the biogas production and zero discharge treatment of a palm oil mill effluent were environmentally sustainable as the system utilized organic waste to produce bioenergy and achieved zero discharge. However, there were other aspects that should be taken into consideration, particularly regarding the sources of electricity and upstream activity, to ensure the sustainability of the system holistically.

Based on the results of analysis and evaluation at the reflection stage, the results showed that, the application of Science Community Technology approaches effectively improve the process / activity and learning outcomes in the Water Recycle material in every cycle of action.

Implementasi Konsep Konservasi Air di Gedung Apartemen X

<p>Clean water crisis that occurred in Bandung is caused by land conversion in North Bandung area which is a recharge area into commercial buildings. This increases runoff rate from 40% to 70% that can lead can lead to flooding and reduced groundwater availability. Therefore, it is necessary to save water by implementing water conservation. Considering those problems, this study aims to apply the concept of water conservation in X Apartment building that is located in the North Bandung Region by referring to Mayor Regulation of Bandung in 2016. Water conservation efforts that will be applied are wastewater reuse into water recycle, rainwater harvesting, infiltration well construction and placing water meters. The application of water conservation concept considers two conditions, namely in rainy season and dry season. Total need for clean water can be saved by 45,8% in dry season, while in rainy season clean water can be saved by 31,74%.</p>

POTENSI PENERAPAN PRODUKSI BERSIH DI PETERNAKAN SAPI PERAH CV. MARGO UTOMO KECAMATAN KALIBARU KABUPATEN BANYUWANGI

CV Margo Utomo dairy farm has approximately 99 cows. Livestock activities include feeding, cage cleaning, milking and livestock bathing. High feed and water requirements resultes high amounts of waste feed and waste produced. If wastewater discharged into channel, it could cause water pollution and could reduce environment. There were two types of waste water. The wastewater that disposed directly wastewater in to channel and the wastewater that settled in basin for three days. Steps of this research included field observation, secondary and primary data collection, problem identification, clean production alternatives identification, feasibility analysis and alternative selection based on priority scale of alternative clean production actions. Feasibility analysis includes technique, environment and economy. Assessment of feasibility based on assessment indicators in the form of questionnaires. This study used NPV, IRR, B / C Ratio, and PBP. There were three alternatives based clean production, that could be applied at the CV. Margo Utomo, such as biogas, water recycle , and cleaning pool for cows. Based on these alternatives, biogas was a best priority to applied in the CV. Margo Utomo dairy farm.
