The used of water in Indonesia for various using disposed exceed water supply. One of the efforts to optimize limited water resources is optimimation watershed management with linear programming. Identification of surface water potential in Cicatih watershed, especially in sub-watershed of upper Cicatih, Cibojong river, estimate using GR4J model. This research using discharge data from PLTA Ubrug. Springwater identified based on data from DISTAMBEN. The observation discharge average in Cibojong river was 246 l/s/day and based on GR4J model was 2752 l/s/day. Avaiable discharge was 56241 l/s/day. Grow of the population estimated by exponent method, industry and irrigation area with regression linear. Software Lingo 8.0 was used to help optimize of wáter resources in Cicatih watershed. Based on the result, in 2025, 12 industries and 15784 ha area get the wáter allocation from surface water. About 1083817 people and 75402 ha area get from springwáter. The cost to access surface wáter is higher than in other sectors. It causes the industry to gets an allocation from surface wáter.

Air temperature is an important microclimate parameter in a greenhouse as it influences root growth and controls plant growth and development. Thus, the precise monitor and model temperature under greenhouse is needed to maintain the plants in optimal conditions. This research aims to model the temperature under a greenhouse using energy balance model. The study monitored the temperature inside and outside the greenhouse in a humid tropical environment. Based on the data, heat exchange constants of greenhouse components were derived, they were: 0.0029 (solar radiation), 0.8 (air) and 0.01 (heat exchange from greenhouse component). The calibrated model enables the calculation of temperature inside a greenhouse based on its outside air temperature, wind speed, and solar radiation. Testing the model against an independent time series showed the high accuracy of the model with an R2 value of 0.99, RMSE = 0.0085 and model efficiency Ef = 0.99. Based on the results, most advantageous strategies for air temperature control inside the greenhouse include the control of air ventilation.

The farm is an important sector that affects economic growth. El-Nino and La-Nina climate anomalies have an impact on the farm such as drought. Actions to overcome the limiting factors on marginal land need to be done through technologies application on soil conservation and water management, balanced soil nutrient management and a better understanding of climate anomalies. Therefore, mitigation models development and anticipation of the effects of drought need to be carried out to provide an alternative technology. The research stages was biophysical conditions analysis, hydrological and geological data analysis, and formulation of drought mitigation technology. Based on the research, there is a drought potential that needs to be anticipated. Technology that could be applied are water reservoirs, dykes, infiltration canals, rorak, slot mulch, and reservoir. Soil and water conservation technology can increase groundwater. Method that have a significant impact is making embankments with mulch, which can increase the soil water content up to 56%.Â Keywords: Drought, Farm, Groundwater, Trenggalek

Seawater intrusion promotes the degradation of groundwater quality through excessive pumping activities or natural phenomena such as tidal floods which are popular with coastal areas. Pekalongan city is one of the areas affected by this phenomenon and was analyzed in this study with reference to the 1986 Ad Hoc Sea Water Intrusion (PAHIAA) Decree which classifies water into five based on salinity. This involved using the Integrated Distance Method (IDW) to map and applying the logarithmic equation to determine the dispersion relationship. The results showed seawater intrusion has already affected groundwater quality up to 6.52 km from the coastline for total dissolved solids and electrical conductivity and 7.22 km for chloride ion. The distribution of TDS, EC, and Cl- in the freshwater zone was also recorded to have reached 28.59 km2, 28.36 km2, and 23.95 km2 respectively. It is predicted that in 4 years, there would no longer be freshwater in Padukuhan Kraton Village due to decreasing groundwater quality caused by seawater intrusion. Furthermore, 23.03 km2 Pekalongan area which spread into 4.34 km2 to the West, 0 km2 to the South, 14.39 km2 to the North, and 1.28 km2 to the East of the district has also been affected and was discovered to be caused mainly by tidal flood from Bremi and Tirto rivers.

A Greenhouse has a different microclimate compared to the outside field. Climate parameters such as solar radiation and air temperature are important parameters that affect plant growth and productivity. This research aims to understand the relation of climate factors in the inside and outside Greenhouse, the effect of microclimate on evapotranspiration and to predict the amount og evapotranspiration inside the Greenhouse. Microclimate analysis was held in two stages, the firststage was from February 5 to March 21, 2018 and the second stage from March 19 to April 29, 2019 at the Department of Civil and Environmental Engineering, IPB University. Primary data was measured by the Decagon sensor. Solar radiation was collected using the Decagon PYR Pyranometer sensor and air temperature using the Decagon VP-4 sensor. Based on the result, the daily air temperature inside the Greenhouse was higher than that of the outside. The inside solar radiation was lower than that of outside the Greenhouse. The relative humidity fluctuated, and the air pressure was higher inside the Greenhouse. Evapotranspiration inside the Greenhouse was lower than outside and solar radiation was the most determining factor of evapotranspiration.

Intrusion of sea water is the infiltration of sea water into the soil. This might be caused by a groundwater excessive exploration. Tangerang District is one of the areas that have great potential sea water intrusion. The aim of research was to predict the limit of salt water intrusion based on the value of DHL and TDS. The primary data were measured using a TOA EC meter CM-14P and then were processed using Surfer 9.0 software and ArcGIS. The measurement results was compared with PAHIAA Decision (1986) and Carroll’s Classification (1962). The results showed that the intrusion area could be identified by DHL and TDS values. On the area located far from the beach, intrusion was influenced by the presence of a river in the region. This was indicated by the regression analysis that showed a correlation between distance and value DHL/TDS with a negative slope value. Based on DHL and TDS parameters in observation area, the groundwater conditions in Tangerang District within a radius of 0.095 km to 5 km from the littoral areas are categorized as medium intrusion zone (slightly brackish water) with DHL 1500-1999 μmhos/cm and TDS values 1000-3000 mg/LU.

Organic vegetables grown special in planthouses require special irrigation practice to maintain the optimum range of soil water content throughout the cultivation season. The problem of irrigation is the absence of parameter that used to determine schedule and water irrigation. This research was to figure out whether the sprinkle irrigation used for Kailan vegetable in a planthouse could fulfil the water demand and the total water consumption based on change of water content. Herewith, the daily soil moisture was observed and analyzed the water flow in the soil based on the soil physical and hydraulic properties. The result showed that the soil water content was always within field capacity and permanent wilting point but 87% of cultivation period was lower than readily avaiable water (RAW). This condition indicated that the water irrigation is not optimal. Based on change of soil water content analysis, water consumption for kailan was 55 mm during cultivation with the consumption rate was 1.1 mm/day. The water requirement to attain RAW condition was 130 mm.
