Abstract

Dryland farming provides a promising opportunity in increasing agricultural production in rural areas. But, the lack of available water during dry season poses a problem in developing dryland farming. An effective water conservation technique should be developed to alleviate this problem. The use of a small farm reservoir (embung) can be considered as one viable option for such conservation techniques. The purpose of this research was to study the effectivity of small farm reservoirs to supply irrigation water for horticulture commodities. Two different types of small farm reservoir (SFR) were constructed in the micro catchment for the research, i.e. a) SFR built with concrete, b) SFR built without concrete. SFR built with concrete had higher water available for irrigation, which is 34% higher compared to SFR without concrete. In addition, the empirical equation that was used in this research was quite reliable in predicting colected water in the SFRs. Using 80% monthly rain probability, on average one small farm reservoir with dimension 8 m x 2m x 2 m was able to supply irrigation water for 100 m2 horticulture plants for the whole growing period. Keywords: Small farm reservoir, dry season, irrigation, dryland farming.

Abstract

Kelapa sawit (Elais guineensis Jacq.) merupakan salah satu tanaman yang memerlukan air dalam jumlah yang banyak. Ketersediaan air merupakan salah satu faktor pembatas utama bagi produksi kelapa sawit. Pada musim kemarau kelapa sawit akan mengandalkan cadangan air bawah tanah untuk kebutuhan airnya. Hantaran hidrolik merupakan parameter sifat fisik tanah yang berperan dalam penambahan air bawah tanah. Tujuan dilakukannya penelitian ini adalah mengetahui karakteristik hantaran hidrolik jenuh pada berbagai jenis lokasi yang meliputi gawangan mati, piringan, dan jalan pikul pada perkebunan kelapa sawit PTPN VII Lampung. Karakteristik ini dapat dijadikan acuan pengelolaan lahan agar dapat meningkatkan cadangan air bawah tanah. Nilai hantaran hidrolik jenuh pada lokasi gawangan mati berkisar antara 2.9-30.4 cm jam-1 dengan kelas sedang sampai sangat cepat, pada lokasi piringan berkisar antara 2.5-13.4 cm jam-1 dengan kelas agak lambat sampai cepat, dan pada lokasi berupa jalan pikul nilai hantaran hidrolik jenuhnya berkisar antara 1.6-12.8 cm jam-1 yang berada pada kelas agak lambat sampai cepat. Tingginya hantaran hidrolik pada gawangan mati disebabkan terjaganya struktur tanah oleh tumpukan pelepah yang sudah mati. Hasil penelitian menunjukan bahwa aktifitas pemanenan yang intensif menurunkan nilai hantaran hidrolik jenuh tanah pada areal piringan dan jalan pikul tempat mengangkut hasil panen disebabkan peningkatan kepadatan tanah.

Abstract

Penurunan muka air pada lahan gambut memicu oksidasi dan subsiden, khususnya pada musim kemarau. Agar dampak penurunan muka air dapat dikelola dengan baik, maka perlu dikaji besaran komponen neraca air (water balance) yang meliputi: a) Pre-storage, b) Evapotranspirasi, c) Ruang pori drainase, d) Konduktivitas hidrolik dan e) Drainase. Penelitian ini bertujuan mengkaji komponen neraca air tersebut pada lahan gambut yang ditanami kelapa sawit yang dapat digunakan untuk menetapkan pengelolaan drainase yang optimal. Metodologi yang digunakan dalam perhitungan kedua komponen neraca air adalah persamaan Hooghoudt Steady-State Approach yang diverifikasi dengan pengukuran data lapang terkait tinggi muka air dengan menggunakan piezometer. Penelitian lapang dilakukan pada perkebunan kelapa sawit di Kabupaten Seruyan, Kalimantan Tengah. Selama musim kemarau (Juli-September), evapotranspirasi mencapai 386 mm yang melebihi besaran curah hujan (311 mm). Jumlah air drainase pada periode ini adalah 90 mm atau 1 mm hari-1. Berdasarkan nilai-nilai tersebut terdapat defisit air sebesar 25 mm selama periode musim kemarau. Jika jarak saluran drainase ditingkatkan dari 30 m menjadi 50 mm, maka terjadi surplus neraca air sebesar 34 mm. Namun surplus tersebut hanya mampu menaikan muka air tanah sebesar 2.3 cm dari kondisi awal yang berada pada kedalaman 40-50 cm. Dalam rangka menghambat penurunan muka air pada musim kemarau maka pada masa transisi dari musim penghujan ke musim kemarau perlu dilakukan konservasi air melalui peningkatan pre-storage. Di samping itu kehilangan air drainase perlu ditekan seminim mungkin melalui pengaturan jarak saluran drainase dan penggunaan cascaded stop-log pada sistem saluran tersier.

Abstract

Tropical forest margin conversion to agriculture land in in Lore Lindu National Park has reached an alaming rate. The conversion was trigered by insufficient revenue to support minimal living standard amounted to                  Rp15.000.000,00/year/household obtained from unproductive cacao farming. Each household required another 1 ha new land to at least reach that minimal living standard. Therefore 218 ha of forest land are potentially cleared by farmerin the near future to extend their farming area. Increasing productivity using innovative agro-technolgy should be considered as one important alternative to reduce the need to clear another forest area. Due to the complexity of interrelated variable affected by using innovative agro-technolgy, a model should be used to take account every affected variable such as availability of labour and liquidity in adopting new agro-technology. In this research, agent-based modeling with mixed integer linear programming model (MILP) using MPMAS software (Mathematical Programming for Multy Agent System) was used to analyze impact of balanced fertilizing and irrigation technology to increase cacao land productivity. Balanced fertilizing was insufficient to reach minimum standard living of Rp15.000.000,00 with existing area of cacao land (1 ha/HH), due to the severe water deficit during month of January until February. Combining balanced fertilizing with irrigation water supply can increase productivity reaching minimum standard of living. It was obvious from the modeling that in the ealier period of cacao growth (1-5 year old), deficits in liquidity and labour was encountered. Interplanting cacao with maize at the earlier phase with additional income from livestock can alleviate liquidity shortage.

Abstract

Pesanggrahan river with total extent of watershed about 13,384 ha is one of rivers flowing through Jakarta City that causes flood problem every years. Many effort has been done to reduce flood problem, among others is to build reservoir in watershed, but the effectiveness of reservoir is still questionable. A research aimed to analyze gap of reservoir capacity changes and its influence on hydrological response and to arrange the scenario of reservoir capacity change to improve hydrological response in Pesanggrahan Watershed was done using HEC-HMS Model. Reservoir capacity change scenarios applied to the actual rainfall condition and designed rainfall condition with a certain recurrence interval. The scenarios consist of: reservoir with the exsisting condition (scenario 1), increase depth of reservoir to 5 meters (scenario 2) and build 6 reservoirs on Pesanggrahan watershed (scenario 3). The model was calibrated using daily discharge data from the date of January 10th to April 30th 2009. Model calibration result shows that model is quite accurate to predict peak discharge in Pesanggrahan Watershed with Nash-Sutcliffe efficiency value = 0.9817 and R2 =0.975. Simulation results showed that the reservoir is effective in decreasing its local effect to peak discharge (reservoir area). The presence of reservoir with existing condition reduce only 6.38 % of the peak run off in outlet Kebon jeruk, whereas building of 6 reservoir will reduce 24.6 % of the peak run off in outlet Kebon jeruk.Keywords : HEC-HMS Model, peak discharge, Reservoir capacity change

Abstract

ABSTRACTThe availability of clean water is one of the main problems for the people in Kendari City. Overutilization of groundwater can cause seawater intrusion to groundwater. This study aims to identify and map seawater intrusion distribution to shallow groundwater based on water quality data. Sampling was obtained from 100 dug wells of the inhabitant (n=100) in March-July 2019 with a variation of the distance from the beach 0.04-5.52 km and the elevation of Groundwater (MAT) between 0.43-30.01 MASL. The distribution of shallow groundwater is mapped on the criteria to the value of Electrical Conductivity (DHL) at the standard temperature of 25 °C. The analysis showed that the average groundwater temperature was 29.28 °C, DHL was 393.52 µmhos, Total Dissolved Solid (TDS) was 196.98 ppm, and pH was 6.31. Shallow groundwater, which has been varied intruded with high intruded (26.26%), rather high intruded (14.14%), medium intruded (32.32%), low intruded (6.06%) and not intruded (21.21%). The correlation between distance from the coast to the value of DHL was not significantly correlated (R2 = -0.49), while groundwater level elevation has a significant correlation (R2 = 0.71). The geological factors of alluvial deposits, which generally have low permeability and slope to flat topography, cause seawater intrusion to shallow groundwater.Keywords: sea water intrusion, shallow groundwater, Kendari City ABSTRAKKetersediaan air bersih merupakan salah satu masalah utama bagi masyarakat kota Kendari.

Abstract

In Indonesia, paddy irrigation covers an area of 7,230,183 ha. Ten percent (10%) of those area or 797,971 ha were supplied by reservoirs. As many as 237,790 ha (30%) of those area supplied by reservoirs are situated downstream of Citarum Watershed called Northern Java Coast Irrigation Area or Pantura. Therefore, Citarum watershed is one of the most important watershed in Indonesia. Citarum is also categorized as one of most degraded watershed in Java. The study aimed to evaluate influence of land use change on irrigation water supply in Citarum watershed and land management strategies to reduce the impact. Tremendous land use change occurred in the past ten years in Citarum watershed. Settlement areas increases more than a double during 2000 to 2009 (81,686 ha to 176,442 ha) and forest area decreased from 71,750 ha to 9,899 ha in the same time period. Land use change influences irrigation water supply through 2 factors: a) decreasing storage capacity of watershed (hydrologic functions) for dry season, and b) decreasing storage capacity of reservoirs due to the sedimentation. Change of Citarum  watershed hydrologic function was analyzed using 24 years’ time series discharge data (1984-2008) in combination with rainfall data from 2000 to 2008. Due to the land use change in this time period, discharge tend to decrease despite of increasing trendof rainfall. As a result irrigation area decreased 9,355 ha during wet season and 10,170 ha during dry season in the last ten years. Another threat for sustainability of water irrigation supply is reservoir sedimentation. Sedimentation rate in the past 10 years has reduced upper Citarum reservoir (Saguling) half-life period (½ capacity sedimented) from 294 to 28 years. If proper land management strategies be carried out, the half-life period of Saguling reservoir can be extended up to 86,4 yearsKeywords: Citarum watershed, improved land management, irrigation water supply, land use change, sedimentation [How to Cite: Tarigan SD and RK Tukayo. 2013.Impact of Land Use Change and Land Management on Irrigation Water Supply in Northern Java Coast.
