One of the problems in Tesso Nilo National Park is deforestation through the opening of oil palm plantations. This can affect the ecosystem services of Tesso Nilo National Park, one of which is as a producer of water. Water yield is a key component of the attributes and processes that produce water-related ecosystem services. The importance of Tesso Nilo National Park ecosystem services as water producers needs to be assessed quantitatively and visualized to explain changes in land cover to changes in these services. The purpose of this study was to analyze the annual water yield in Tesso Nilo National Park. The model used is the Integrated Valuation of Environmental Services and Tradeoffs (InVEST) water yield model. InVEST is a spatially explicit tool for exploring how changes in ecosystems tend to lead to changes in benefits flowing to people. The annual water yield in Tesso Nilo National Park in 2018 was 5731528155.86 m3 or 2729.52 mm. Water yield is strongly influenced by actual evapotranspiration (AET), mean annual rainfall (MAP), and land cover (LC). The land cover that produced the lowest to the highest water yield was mixed acacia, forest, oil palm plantations, bare land and shrubs.

A field experiment was conducted to evaluate the evapotranspiration (ET), crop coefficient (Kc), and water use efficiency (WUE) of rice in two unique transplanting systems: Jejer Manten (JM) and Jajar Legowo (JL) under irrigated conditions. Research studies in Indonesia attribute JM and JL with high yields and water productivity compared to the conventional tile (TL) system using Indica rice. There is no scientific research on the effect of JM and JL on ET for estimating Kc in both Indica and Japonica rice. The aim of the study is to evaluate the influence of JM, JL, and TL on ET, Kc, and WUE of Japonica rice at different rice growth stages. Crop ET and water surface evaporation beneath the rice canopy (Ew) were measured by lysimeters installed in each transplanting system. The average of Kc was calculated at the vegetative, reproductive, and ripening stages. The yield was higher in JM and JL compared to TL. In terms of water conservation and efficiency, JL outperforms JM and TL due to lower ET, Kc values, and higher WUE. Selecting an appropriate transplanting system is subject to local conditions and water availability .

“…Therefore, the accurate representation of ET is important for rainfall-runoff modeling due to its impact on the hydrological responses (Anggraheni et al, 2018), but unfortunately, many watershed in Indonesia lack sufficient ET measurements. To address this issue, previous study was conducted where ET was calculated using a variety of numerical models, such as Penman-Monteith (Aprialdi et al, 2019;Widyanto et al, 2014), Thornthwaite method (Pramudya et al, 2019), and modified Penman (Batchelor, 1984).…”

Evapotranspiration is an essential part of water availability analysis and crop water needs that are useful to estimate irrigation water demand. Since discharge measurement stations are limited, the analysis of water availability is the most important part of water management planning. Citarum watershed is the biggest watershed in West Java, supplies raw water to Jakarta, the capital city of Indonesia. Modified Penman is the common equation to analyze evapotranspiration, which was developed by Food and Agriculture Organization (FAO) and modified for tropical areas. Evapotranspiration is one term of the water balance equation. To determine water losses, it is necessary to solve this equation. Another source of evapotranspiration data is provided by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite's standard product, MOD16A2. In order to used the evapotranspiration satelilite data to fullfill the lack of groud station data, the reliability of satelite data is needed. The objective of this study is to compares and analyzes the reliability of satellite evapotranspiration potential images with the numerical Modified Penman method at Citarum Watershed. Modified Penman is one of several methods that calculate the evapotranspiration potential based on climate data. MOD16A2 was used for simulation data, and Modified Penman was used for baseline data. The reliability of the two simulations was analyzed by the skewness percentage of each pixel and period. The distribution of percent skewness indicates the performance of satellite evapotranspiration on the Modified Penman that represents the actual condition. The sensitivity of satellites is greatly affected by local weather conditions.
