Abstrak. Kabupaten Aceh Selatan memiliki rerata curah hujan bulanan yang sangat tinggi sebesar 281,4 mm/bulan, sehingga memiliki potensi aliran permukaan yang tinggi. Ketersediaan curah hujan yang melimpah pada musim hujan belum dimanfaatkan secara optimal pada musim kemarau. Air hujan sebagian akan menjadi aliran permukaan sehingga tidak bisa dimanfaatkan tanaman secara efektif. Dampak dari terjadinya aliran permukaan yang tinggi akan menyebabkan hilang humus tanah sehingga terjadinya penurunan kesuburan lahan. Desain teknis sistem pemanenan air hujan yang efektif untuk konservasi air tanah dan memenuhi kebutuhan air tanaman pala telah dapat dibuat dengan rincian sebagai berikut: Sistem pemanenan air hujan pada penelitian ini menggunakan rorak yang dilengkapi saluran peresapan. Tata letak rorak dan saluran peresapan menyesuaikan dengan kontur lahan. Dimensi rorak ditentukan sesuai dengan debit aliran permukaan, yaitu kedalaman maksimal 30 cm dengan lebar 40 cm danpanjang 100 cm. Setiap rorak disertai saluran peresapan dari sisi kiri dan kanan dengan panjang 100 cm, dalam 10 cm dan lebar 20 cm.Abstract. South Aceh district has a very high average monthly rainfall of 281.4 mm/month, so it has a high potential of runoff. The availability of abundant rainfall during the rainy season has not been used optimally in dry season. A part of rainfall would become surface flow so that the plant cannot use it effectively. The impact of high surface flow will cause in loss of soil humus which leads to the decline of soil fertility. Technical design of rainwater harvesting systems which is effective for soil and groundwater conservation and for fulfil water needs from nutmeg crops could be constructed as : rainwater harvesting systems by using rorak equipped with infiltration channels. Rorak layout and channel infiltration should be adjusted to the contour of the land. Rorak dimensions are determined by the discharge of surface flow, which has the maximum depth of 30 cm, width of 40 cm and length of 100 cm. Each rorak is built with infiltration channels on the left and right side with lengt hand depth of 10 cm and width of 20 cm.

Pemenuhan kebutuhan pangan dan gizi penduduk di suatu daerah ditentukan oleh ketersediaan, kecukupan serta konsumsi pangan suatu daerah yang selanjutnya dibandingkan dengan potensi sumberdaya hayati, sarana dan prasarana produksi yang tersedia di daerah tersebut. Produksi bahan pangan optimum dan luas lahan yang optimum untuk memenuhi kebutuhan pangan penduduk diprediksi dengan pendekatan optimasi kebutuhan (demand) dan produksi (supply) sumberdaya hayati untuk pangan dan gizi. Proyeksi kebutuhan dan ketersediaan bahan pangan suatu daerah dapat dioptimasi menggunakan perangkat lunak OptifoodPlus. Ketersediaan energi pangan Kabupaten Aceh Selatan sampai tahun 2020 diproyeksikan jauh melebihi dari proyeksi kebutuhan energi pangan. Proyeksi ketersediaan energi pangan dari kelompok bahan pangan serealia jauh melebihi proyeksi kebutuhan energi pangan dari serealia, sedangkan rata-rata ketersediaan energi pangan dari serealia masih berada di atas rata-rata konsumsi serealia perkapita nasional sejak tahun 2005. Demikian juga proyeksi ketersediaan produksi padi sawah jauh melebihi proyeksi produksi optimum padi sawah dari tahun 2001-2020. Ketersediaan lahan padi sawah berdasarkan luas baku lahan sawah Kabupaten Aceh Selatan seluas 17.713,50 ha dan berdasarkan kesesuaian lahan untuk tanaman pangan lahan basah mencapai luas 39.971,78 ha yang terdiri dari 1.350,15 ha (cukup sesuai) dan 38.621,63 ha (sesuai marjinal), ternyata jauh melebihi proyeksi kebutuhan lahan optimum (luas panen) untuk memproduksi padi sawah sampai tahun 2020 yang hanya 9.785,27 ha. Berdasarkan hasil optimasi ketersediaan pangan dan kebutuhan pangan, dapat disimpulkan bahwa Kabupaten Aceh Selatan mempunyai potensi ketahanan pangan dan berpotensi sebagai daerah mandiri pangan.

Runoff is one of flood and erosion causal factor in Indonesia. Runoff occurred when rainfall cannot be infiltrated and flowed on the ground surface. Cidanau watershed has quite high rainfall average (2573 mm/year) so it has high runoff potential. Zero Runoff System (ZROS) is one of water conservation way which can infiltrate runoff to the ground using permeation structures. ZROSâ€™s successful parameter in order to decreasing runoff rate can be observed by the soil water content differences before and after ZROS application. Soil water content estimation was conducted by water balance model with and without runoff and then it is compared with soil water content from measuring. The simulation results indicated that soil water content in the research field before and after ZROS application is 0.476 and 0.569 m3/m3 respectively. The simulation is also conducted for past 10 years (2004-2013) and resulted higher soil water content if ZROS were applied. This results indicates that ZROS capable to decrease and permeate runoff to the ground and then increase soil water content level. Water balance model with and without runoff has coefficient of determination (R2) 0.606. It means that this model could simulate the soil water content differences before and after ZROS application valid relatively.

One of the obstacles in providing irrigation water is the difficulty in determining the right parameters to be used in the controlling of timing and amount of irrigation water according to crop needs. One of the alternative parameters that could be considered in order to meet the water needs of plants is the irrigation control based on evaporation. This study aims to produce an evaporative irrigation system design and determine the crop coefficients of pepper. The drip irrigation network consists of a supply tank and distribution pipes that provide water to the plant pots. The network valve opening and closing arrangements are made based on the evaporation in the supply tank. This research was conducted in a plant house for 5 months by observing the observations made on the water balance components, including the rate of evaporation which is measured based on changes in the water level in the water supply tank. The results showed that the evapotranspiration outside the houseplant was greater than that in the plant house. At the beginning of planting pepper, the evapotranspiration was 5.2 mm/day in the plant house and 4.9 mm/day outside. The average evapotranspiration during observation inside the plant house was 4.1 mm/day and 3.8 mm/day outside. Meanwhile, evaporation outside the plant house is smaller than that inside the plant house which ranges from 2-5 mm/day. Provision of water with this evaporative irrigation system of 5.2 mm/day has been able to meet the needs of 4.1 mm/day of evapotranspiration water for pepper plants. The provision of water has been able to encourage the growth of primary branches and flowering. Normal pepper plant growth during this study with calculated crop coefficients ranging from 0.1â€“0.7.

The paper describes economic valuation for the Cidanau watershed area of West Java in Indonesia. In this area natural resources deterioration has occurred even faster after the Asian Financial Crisis. The deforestation area and pronounced soil erosion seems to go unhindered because of land use competition among the residents for agricultural space, housing, etc. In order to prevent the area from further degradation, the purpose of this paper is to carry out quantitative evaluation which also attempts to raise the environmental awareness of residents, as well as visitors to the area. Questionnaire surveys were conducted and analyzed according to the Contingent Valuation Method (CVM) and the Travel Cost Method (TCM). The results show all respondents held good attitudes towards the efforts of environmental conservation, but responded negatively if they had to contribute to the environmental service payment. Visitors to the Anyer Beach acted differently because most of them come from faraway locations and have little knowledge of the watershed. However, the Anyer Beach recorded an environmental valuation of about Rp840 billion, which is a potential source for the service payment of Cidanau watershed.

The concept of hydrological tank model was well described into four compartments (tanks). The first tank (tank A) comprised of one vertical (qA0) and two lateral (qA1 and qA2) water flow components and tank B comprised of one vertical (qB0) and one lateral (qB1) water flow components. Tank C comprised of one vertical (qC0) and one lateral (qC1) water flow components, whereas tank D comprised of one lateral water flow component (qD1). These vertical water flows would also contribute to the depletion of water flow in the related tanks but would replenish tanks in the deeper layers. It was assumed that at all lateral water flow components would finally accumulate in one stream, summing-up of the lateral water flow, much or less, should be equal to the water discharge (Qo) at specified time concerns. Tank A received precipitation (R) and evapo-transpiration (ET) which was its gradient of (R-ET) over time would become the driving force for the changes of water stored in the soil profiles and those water flows leaving the soil layer. Thus tank model could describe th vertical and horizontal water flow within the watershed. The research site was Cisadane Upper Catchment, located at Pasir Buncir Village of Caringin Sub-District within the Regency of Bogor in West Java Province. The elevations ranged 512 –2,235 m above sea level, with a total drainage area of 1,811.5 ha and total length of main stream of 14,340.7 m. The land cover was dominated by forest with a total of 1,044.6 ha (57.67%), upland agriculture with a total of 477.96 ha (26.38%), mixed garden with a total of 92.85 ha(5.13%) and semitechnical irigated rice field with a total of 196.09 ha (10,8%). The soil was classified as hydraquent (96.6%) and distropept (3.4%). Based on the calibration of tank model application in the study area, the resulting coefficient of determination (R2) was 0.72 with model efficiency (NSE)of= 0.75, thus tank model could well illustrate the water flow distribution of Cisadane Upper Catchment. The total water yield was 2.789 mm year-1 from 3,624 mm year-1 of total annual precipitation. The total water yield comprised of a total runoff of 47.39% and 49.23% of sub surface flow and base flow.

Forest fire research is very important for tropical regions as the current available models on forest fire predictions and control were developed based on studies conducted in dry sub-tropical forest areas. The use of dryness index (DI) based on actual soil water content for assessing fire danger in wetland ecosystem was proposed in this paper. The study site was located in South Sumatera, Indonesia and study was conducted from April 1 st 2009 to March 15 th 2011. Fire danger was categorized into 4 levels; low, medium, dry, and extreme with its margin level was determined based on soil water retention curve analysis. All DI categories occurred in 2009, however only 2 categories (low and medium) were observed in 2010 and 2011. DI reached its maximum intensity in September 2009 with an onset rate of 1.4 per day based on analysis of time intensity curve. Information of onset rate is importance for forest fire management such as for estimating when the extreme category would be reached. Therefore anticipation and prevention efforts might be prepared prior to reaching certain danger level. Information on DI might be useful for water management planning in forest plantation areas as many of them are located in wetland ecosystem.

Climate change causes uncertainty in water availability. The change may include annual rainfall, evapotranspiration and the shift of rainy and dry seasons, thus, it affects hydrological response in the region. Water demand will increase over time with population, industrial and business growth but the water availability has not been ascertained to sustainably satisfy those needs. Cidanau Watershed has wetland ecosystem so-called the Rawa Danau (Caldera), with an area of around 2,500 ha. This watershed receives average annual rainfall around 2,500 mm. Climate change especially the local climate in the region of Cidanau was analyzed to illustrate how the relationship with Cidanau river discharge. It is expected that climate change does not affect the water availability in the watershed. In this study, the analysis of local climate change and its impact on the availability of water resources on Cidanau Watershed was based on climate trends, water balance analysis, and estimation of discharge of Cidanau Watershed. This research was carried out using climate data and discharge from 1996 until 2010. The results showed that climate variables have changed from 1996 to 2010. This change mainly occurred in temperature, annual rainfall, and evapotranspiration. Based on the analysis, the discharge of Cidanau Watershed will decrease due to changes in rainfall and evapotranspiration. The estimated minimum river discharge of Cidanau Watershed ranges from 0.5 to 1 m3/s until 2050.
