Abstract The thermal comfort standard can be accessed with a predicted mean vote (PMV) index that has six variables: air temperature, velocity, relative humidity, radiant clothing insulation, and metabolism rate. Calculation of the room issued PMV is quite complicated, considering determination effect parameters take long time because it non-linear relationship. purpose this study to analyze sensitivity affect develop an artificial neural network model predict two different input scenarios....

Rewetting peatland is an ongoing effort in Indonesia to restore the hydrological cycle and carbon balance of ecosystem. However, quantifying impact rewetting on mitigating fire remains a challenge. Here, we assess large-scale risks occurrences (duration, coverage area, number events) 2015–2021. The weather research forecasting (WRF) model was integrated with drought–fire spatially quantify hazards Riau, Sumatra. results show that has resulted decreasing frequency extreme events study area...

Since 2017, the installation of Sheet-pipe system in Indonesia has marked a significant development. This initiative, collaboration between Ministry Agriculture and Japanese construction company, aims to improve water management rice paddies. The was specifically installed at Sukamandi Rice Research Center West Java, covering an area 3600m 2 . Seven parallel sheet-pipe lines, each 100 meters length 40 cm deep, were laid out. These lines consolidated into three drainage outlets regulated by...

The use of Cyrene™ as an alternative non-toxic solvent to produce a PVDF-based ultrafiltration membrane was investigated in this study. Polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) were used organic additives explore its ability improve hydrophilicity. introduced into the casting solution via phase inversion with combined non-solvent induced separation (NIPS) evaporation-induced (EIPS) technique. prepared membranes characterized examine morphology, mechanical properties,...

Total soluble solids (TSS) and fruit fresh weight are two indicators to show the quality of tomato fruits.To gain high values TSS weight, it is important consider concentration nutrient solution, which commonly represented by Electrical Conductivity (EC) value.Generally, increasing EC value not only increases number TSS, but also decreases weight.Therefore, optimize for both fruits.The objective this research solution on each generative stage using Artificial Neural Network (ANN) Genetic...

The System of Rice Intensification (SRI) for improving rice production has been attracting worldwide attention its relatively high yield and greater water productivity (WP). One distinctive characteristic SRI paddy fields is maintaining groundwater level (GWL) close to the soil's surface as dynamic aerobic–anaerobic soil conditions enhance crop growth. We investigated performance when subjected a gradual lowering GWL assess consequences this yield, WP, greenhouse gas (GHG) emissions....

The current study initiated to investigate crop coefficient (Kc) and water productivity between conventional System of Rice Intensification (SRI) irrigation regimes terrace rice fields in Indonesia. Kc value represents plant responses available the its information is very important determine evapotranspiration. field experiments were conducted belong local farmer located Wonogiri, Central Java (S 7o47’18.66”, E 111o5’51.26”) during 21 July – 7 November 2014 dry season. Here, there two with...

Subsurface drainage technology may offer a useful option in improving crop productivity by preventing water-logging poor paddy fields. The present study compared two fields with and without sheet-pipe type subsurface on land water productivities Indonesia. Sheet-pipe typed is perforated plastic sheets hole diameter of 2 mm made from high-density polyethylene. It commonly installed 30–50 cm below the soil surface placed horizontally machine called mole drainer, then will automatically be...

Water saving in rice cultivation has assumed paramount importance, especially the context of climate change. The introduction sheet-pipe technology Indonesia, heralded as an innovative subsurface irrigation and drainage system, is poised to revolutionize how manage this vital resource. Our study was designed with two primary objectives: first, investigate plants respond when water levels are deliberately reduced using technology; second, comprehensively analyze productivity use efficiency...

The odor affects both one’s health and quality of life. This study measures analyzes concentration sources in ambient air, the correlation between gas hedonic scale, design an odor-reduction instrument. research commenced from February to May 2022 small industrial area (SIA) Magetan Regency compost bins Bogor City. Data was collected through chemical analysis, scale measured at four points divided into radii one two. parameters City is below standard, while ammonia low. Regarding biofilter,...

Broiler-closed houses typically lack reduction technology, leading to environmental issues, namely odor. Processing technology can be used, biofilters. This study aims design and construct a closed-house biofilter perform test on the reduce odors. Odors are measured by odor gas concentration (ammonia hydrogen sulfide) hedonic scale panel method. The consisted of an source (closed house), humidifier, reactor. Factors that influence size reactor from removal activities include air flow rate,...
