Abstract

Peatlands drainage system aimed to eliminate the limiting factors to support better growth of plants. Drainage practices will cause subsidence and be associated with CO2 emission. The purpose of this study was to observe the subsidence rate on tropical peatlands of oil palm plantations at different ages and to establish the percentage of decomposition of peat materials from the subsidence rate. Subsidence was measured in 9-, 12-, and 17-year-old of adjacent oil palm planting blocks with peat thickness of about 5 m and have been drained for 10–18 years, two samples taken for each block every three month. Peat decomposition was measured in the 12-year-old block automatically using LiCor Li-8100A with 30 minutes recording interval. Peat decomposition (heterotrophic respiration) considered as actual CO2 emission was compared to emission calculated from subsidence and considered as potential CO2 emission. The average subsidence rate observed for one year in the three age classes of oil palm plantations was 2.47 ± 0.76 cm/year. The percentage of CO2 emissions from the decomposition process to subsidence on drained 12-year-old oil palm on tropical peatlands was 41.05%. The subsidence data indicates that consolidation still the main process of subsidence in this peatland.

Abstract

Purwakarta Regency is one of the regencies in West Java Province that plays an essential role in agricultural development. One of the efforts to encourage sustainable agricultural development is by developing potential commodities so that scenarios can be drawn up that are in accordance with the region's potential. Optimum land use scenarios with several constraint targets need to be prepared by considering food needs, ecological sustainability, and farm income. This study aims to identify land available for food commodities and simulate the land use allocation of food commodities in Purwakarta Regency to meet food needs, farm income, and tolerance for erosion. Location quotient index, shift-share analysis, land suitability & capability analysis, and Multiple Goals Programming were used to achieve research objectives. The identified leading commodities are peanuts, cassava, and sweet potato. We suggest 15 classes of land available for optimum land use allocation. Space optimization is organized into four scenarios considering erosion control targets, meeting farmers' minimum incomes, and rice production. The smallest erosion is 13,159 tons/ha/year, while the highest possible income is IDR300,500,000,000. The highest rice production is 202.070 tonsGKP, cassava production is 16,919 tons, sweet potato is 2.014 tons, and peanut production is 531 tons. Achieving production targets can support agricultural development and food security improvement programs through sustainable production improvement.

Abstract

Government of Indonesia planned to build 30.000 embung in 2017. Embung or mini reservoir is one of soil and water conservation methods to decrease surface runoff, enhance water surface retention, and increase water entering to the soil by infiltration, that finally influence the values of Discharge Ratio and Runoff Coefficient of a watershed. This research that was done in 2017 is about the effect of embung and it’s combination with other soil and water conservation technics (strip cropping and agroforestry) on Discharge Ratio (DR) and Runoff Coefficient (RC) in Cilemer Watershed by using SWAT method. The result shows that the Scenario 1 (mini reservoir technic alone) decreased DR and RC by 25.45% (from 119.70 to 94.25) and 32% (from 0.25 to 0.17), respectively. The Scenario 2 (combination of embung and strip cropping) decreased DR and Runoff Coefficient by 40.92% (from 119.70 to 78.78) and 32% (from 0.25 to 0.17), respectively. The Scenario 3 (combination of mini reservoir and agroforestry) decreased DR and RC by 41.38% (from 119.70 to 78.31) and 36% (from 0.25 to 0.16), respectively. The application of mini reservoir and its combination with other soil and water conservation (SWC) techniques were able to decrease DR and RC meaningfully.

Abstract

Currently, water resources management is still focused on on-site water resources infrastructure to achieve optimal water utilization, with almost never considered land management in which water resources are produced naturally. The research aim is to study the water balance in the Upper Cisadane Sub-Watershed, and to simulate a land use plan and development of water resource infrastructure to fulfill the need for water in the Upper Cisadane Sub-Watershed using the SWAT (Soil and Water Assessment Tool) model. Existing water availability was calculated using stream discharge data from River Flow Measurement Station Empang, whereas water demand has been analyzed for domestic, industries, agriculture, fisheries, and animal husbandry. Totally, water availability in the Upper Cisadane Sub-Watershed was ± 222.9 MCM (Million Cubic Meters) year-1, which was higher than the demand for water of as much as ± 209.8 MCM year-1 and resulted in a water surplus of ± 13.1 MCM year-1. However, water availability was not evenly distributed throughout the year, and there was always a water deficit in the dry season. To overcome drought during the dry season, five simulations of land use management and construction of water retention infrastructure were carried out using the SWAT model. The water deficit in the Upper Cisadane SubWatershed will be overcome by the consistent application of the spatial plan of West Java Province, reforestation of converted forest areas, applied agroforestry in agricultural land, and development of a reservoir with a storage capacity of 30 MCM.

Abstract

The hydrological function of peatlands, one of which is acting as a medium for storing and releasing water, undergoes alteration due to degradation. Saturated hydraulic conductivity (Ks) is a pivotal parameter for comprehending the hydraulic properties of peatlands. Ks plays a crucial role in the transmission and release of water influenced by other peat properties. This research examined the impact of Ks and selected peat properties, namely bulk density and available water content, to depict the hydrological function in rewetted peatlands. The study sites are rubber plantation (RB), oil palm plantation (OP), and drained secondary forest (SF). Results revealed a significantly higher Ks in OP (106.7 cm hr-1) compared to RB (19.56 cm hr-1) and DSF (15.1 cm hr-1). The hydrological function at all study sites was categorized as high, with minor degradation in OP and moderate degradation in RB and SF. Nonetheless, these findings necessitate fundamental interpretation and adjustment. The outcomes of this study can be utilized to prioritize rewetting efforts in the study sites, emphasizing the importance of prioritizing immature peat (fibric) with high Ks.

Abstract

Cisangkuy watershed is the main source to meet the demand for raw water in Bandung city and Bandung Regency. The current hydrological condition has decreased as indicated by high fluctuations in river flow. The objectives of this study were to evaluate land use changes and water availability in the Cisangkuy watershed and to develop recommendations for land use to increase water availability in Bandung Regency based on the results of the hydrological simulation. There are some data used for analysis including land use map, spatial planning maps of Bandung regency, population numbers, industrial water demand, discharge, rice field area, freshwater fish pond area and the number of livestock. In summary, this research phase begins with an evaluation of land use changes , then calculates the water balance using the SWAT model. Changes in land use in the Cisangkuy watershed from 2007-2017 occurred from vegetated land cover to non-vegetation, which had an impact on the hydrological system and the availability of water in the Cisangkuy watershed. The potential for surface water supply in the Cisangkuy watershed with the existing scenario (in 2017) is 495.58 million m3 and the total user consumption water demand is 592.78 million m3, so there is water balance deficit about 97.20 million m3. The application of scenarios for improving land management by increasing the area of mixed dry land agriculturalwith agroforestry methods, reforestation on plantation forest land, applying infiltration wells in settlements and applying terraces to paddy fields provides a fairly good hydrological response to reduce the raw water deficit from 174,91 million  to 63.98 million m3.Keywords: land use change, water supply, water demands, water balance, Cisangkuy Watershed
