Abstract

Hydroponics is an agricultural farming system that does not use soil media but uses water media containing nutrient solutions. The purpose of this research is to measure and observe dissolved oxygen levels in the Smart Watering Unpad and Autopot Systems that have never been done before. The research was conducted using descriptive analysis method that is measuring, observing, calculating, and analysing quantitative data on hydroponic installations Smart Watering Unpad and Autopot. The fertigation used in this study were Smart Watering Unpad and Autopot with the parameters observed were ambient temperature, dissolved oxygen, and the relationship between ambient temperature and Dissolved Oxygen for 30 days of observation. The results showed that the response of dissolved oxygen levels was influenced by environmental temperature in the SWU 01 Lettuce, SWU 02, SWU 03, and SWU 01 Paprika systems had a NEGATIVE relationship direction. The Autopot system is the only installation that has a POSITIVE change in the relationship of dissolved oxygen levels influenced by ambient temperature. Autopot is a hydroponic installation that can maintain the availability of dissolved oxygen levels in the nutrient solution. The Smart Watering Unpad 02 installation can maintain the availability of dissolved oxygen levels in the nutrient solution compared to other installations in the Smart Watering Unpad system type.

Abstract

This research aim to identify the characteristics catchment area of jatiroke and present in the form of spatial data. The descriptive method was employed in this study. The results showed of Jatiroke catchment area was 5695,80 ha. Schmidt-Ferguson and Oldeman's classification of climate puts the climatic characteristics of the Jatiroke catchment area in the same group as type C and type C3. The Jatiroke catchment area has an elongated and narrow shape (like a bird feather), which impacts the amount of water that enters the river. The Jatiroke catchment area has an elongated and narrow drainage pattern and is shaped like a bird's feather based on the characteristics of the watershed. Land cover in the Jatiroke catchment area is dominated by forest mixed covering an area of 1615 ha with a percentage of 28%. Andosol and Kambisol soil types are found in the Jatiroke catchment area. Kambisol soil type dominates with an area of 3245.57 ha with a percentage of 57% of the total area. The slope of the Jatiroke catchment area is dominated by moderately steep and steep slope classes with an area of 3905.4 ha and 3278.2 ha, respectively, with an area presentation of 27.75% and 23.29%.

Abstract

Cikeruh-Citarik sub-watershed is a part of the upstream zone of the Citarum watershed which is classified as a watershed with critical conditions in West Java. The change in land use as a side effect of the increasing population causes a degradation of the watershed. Land-use change in a watershed without considering any conservation rules leads to erosion, becoming a watershed criticality indicator. Erosion can be minimized by using a prediction model to predict the amount of erosion that might happen, for the result could help to decide which conservation action is needed in the watershed rehabilitation. GeoWEPP is one of the prediction models that is suitable for predicting the amount of erosion on a watershed scale. This research aims to study the preparation of the input data needed in the GeoWEPP model to predict the amount of erosion, especially in the Cikeruh-Citarik sub-watershed. The methodologies that were used in this research are literature study and field survey. According to the research results, the input data needed for GeoWEPP are DEM (Digital Elevation Model) data of the research area, climate database, soil type and soil physical properties database, land use and landcover data, and bridge files for soil, land cover data, and evapotranspiration calculation.
