Abstract

To understand the prospect of groundnut development (Arachis hypogaea) for supporting food security in semi arid area, survey and experiment of groundnut varieties were undertaken in Makamenggit Village, East Sumba District, the East Nusa Tenggara Province. Aim of research was to understand natural resources (soil, climate and water) and production potency based on cased study of 6 (six) varieties of groundnut which was cultivated under manure treatment. The six groundnut varieties, i.e. Tupai, Komodo, Zebra, Gajah, Bogor variety and Makamenggit local variety were cultivated in vertisol soil type, organic manure of buffalo feces, irrigation manually from water river in dry season. Parameters of plant height, leave number, and leave cover each individual plant were observed every week, since 5 weeks until 12 weeks after planting. Survey indicated that agro-climate and hydrology of East Sumba was very potential to support groundnut development not only in the rainy season short period (3-4 months), but also in the dry season by utilization of the existence of waterresources (some river and ‘embung-embung’). Result of research showed that six varieties of groundnut had good vegetative growth. The Makamenggit local variety which showed vegetative growth so good performance was potential to promote as a national superior seed. It was obviously that organic manure could increase groundnut vegetative growth (and also reproductive yield) at the vertisol soil type. To develop groundnut cultivation in East Sumba area the utilization of organic manure, cultivation in dry season by irrigation of limited water and seed diversity need to be socialized continuously to the farmers.Keywords: natural resources, prospect, groundnut, food security, east Sumba.

Abstract

Effort to increase water used efficiency is one of the important aspect in the integrated embung management. The others are watershed and water storage management. Water used efficiency related, the first problem is how to deliver water from the embung storage to the water utilization area (village); and the second problem is how to use water for people consumption, cattle feeding and plant irrigation efficiently. Since theOemasi embung was built in 1991/1992 untill in 2010 some aspects were developed related to the increasing of people population in this area, i.e. developing of water tanks for people water consumption, cattle and irrigation; application of water used efficiency for cultivation of horticulture plants by using polybag potting system; and pipe network rehabilitation programme. The Oemasi embung problem and solution during the 20years of embung maintainance are the very valuable experience that can be used as a case study to manage 333 embungs that were built in the East Nusa Tenggara Province.

Abstract

     ‘Embung’ Sirani, located 10 km from the capital city of Belu District, East Nusa Tenggara Province, is the biggest of the 27 ‘embungs’ in this area. The ‘embung’ has 211.2 of watershed area, 20 m of water depth and 1.860.000 m3 of water storage capacity to irigate rice field. To promote the unic and strategic ‘embung’ as an ecotorism object, an ecohydrologic study was conducted in 2008. Ecotourism objects which can be developed around the Sirani ‘embung’ in Belu Districts are the lake tourism, canoe ride around the ‘embung’; agro-tourism of horticulture plant and fishing pond at the ‘embung’ downstream; and agroforestry-tourism at the watershed area. ‘Embung’ ecotourism as an integrated conservation by participation of the local people is needed to develop.

Abstract

ABSTRACT ?Embung? is one of the collected and served water constructions for domestic consumption, cattle drinking and irrigation in the border area and dry climate of Belu District, East Nusa Tenggara (ENT) Province. The others are water source from shallow soil-water digging and natural springs.  There are 26 small ?embungs? which have 11,700 ? 96,830 m3 water volume  and the biggest ?embung?  which has 1,860,000 m3 water volume; 276 springs, and some shallow soil-water digging.  ?Embungs? sustainability are influenced by some aspects such as technical problem since construction developed, utilization, social and management.  Due to the natural resources and budget handicap, generally in one village just exist one type of the three water collected constructions. However, it is possible in one village there are three constructions, i.e.: ?embung? is particularly for cattle drinking and irrigation; and the shallow soil-water digging and natural springs are specially for water domestic consumption. These man made and natural water source are very valuable to serve farmers in the Belu-ENT village area.   Key words : sustainability, ?embung?, border area, dry climate, Belu-NNT.   ABSTRAK   Embung merupakan salah satu bentuk bangunan penampungan dan pelayanan air untuk rumah tangga penduduk, minum ternak dan irigasi di wilayah perbatasan dan beriklim kering Kabupaten Belu, Provinsi Nusa Tenggara Timur  (NTT). Bentuk bangunan yang lain adalah sumur air tanah dangkal (kedalaman kurang dari 30 m) dan sumber-sumber air alam.  Terdapat 26 embung-embung kecil dengan kapasitas tamping  11,700 ? 96,830 m3 air  dan, sebuah embung paling besar dengan kapasitas tampung 1,860,000 m3 air; 276 sumber air alam dan beberapa sumur air tanah dangkal.  Kelestarian embung-embung, dipengaruhi oleh berbagai aspek, seperti faktor teknis saat embung dibangun, pemanfaatan, sosial dan pengelolaan.  Oleh karena keterbatasan sumberdaya alam dan anggaran, pada umumnya di sebuah desa hanya terdapat satu tipe sumber air.  Meskipun demikian, dimungkinkan pada sebuah desa terdapat tiga bangunan sumber air, yakni:  embung khusus hanya untuk minum ternak dan pertanian;  sumur gali air tanah dangkal dan sumber air alam untuk memenuhi kebutuhan rumah tangga.  Baik sumber air alam maupun buatan tersebut sangat bermanfaat untuk melayani kebutuhan petani di wilayah perbatasan Belu-NTT.   Kata kunci : pelestarian, embung, wilayah perbatasan, iklim kering, Belu-NTT.

Abstract

ABSTRACT   Effort to re-vegetation of  ?embung? watershed and environment was carried out in  the border area and dry climate, Belu District-East Nusa Tenggara (ENT) Province, 2006-2008.  Based on initial study consisted of ecological, runoff and erosion risk of ?embung?  watershed and its environment, the some local and adapted species were cultivated  to remediate and conserve the degraded area. Evaluation of plant and environment development after three years effort was conducted on  April 2011. The research indicated that species which were planted in the surrounding village of Leosama and Sirani Haliwen ?embung? were very well growing.  On the other hand, species which were planted at the Leosama ?embung? watershed were bad growing, due to the serious handicap of wild cattle, degraded soil, water shortage and social culture.  The research concluded that effort to re-vegetation of a serious degraded area  need  to be backed up by the village nursery garden in the location which have soil and environment more favorable.  By this way we can minimize risk to re-vegetation of the big scale degraded area. Key words : re-vegetation, embung, environment, Belu-NNT   ABSTRAK   Upaya untuk penghijauan daerah tangkapan air dan lingkungan embung, telah dilaksanakan pada tahun 2006-2008.  Berdasarkan studi ekologi, resiko aliran permukaan dan erosi daerah tangkapan air dan lingkungan embung, telah ditanam beberapa jenis tumbuhan lokal dan adaftif utuk pemulihan dan konservasi lahan terdegradasi.  Evaluasi pertumbuhan tanaman dan perkembangan lingkungan, telah dilaksanakan pada bulan April, tahun 2011.  Penelitian menunjukkan, bahwa jenis tumbuhan yang ditanam di sekitar perkampungan penduduk Desa Leosama dan Desa Sirani-Haliwen lebih bagus dibandingkan yang ditanam di daerah tangkapan air.  Hal ini karena terjadi hambatan serius dari ternak liar, lahan yang sangat marginal, keterbatsan air dan sosial budaya masyarakat.  Dari hasil penelitian dapat disimpulkan, bahwa untuk penghijauan lahan dengan kondisi fisik dan lingkungan sangat marginal perlu ditunjang dengan pembangunan kebun bibit desa dengan kondisi lahan dan lingkungan yang lebih baik. Cara tersebut diharapkan dapat mengurangi resiko kegagalan pada penghijauan dengan skala yang lebih luas.   Kata kunci : penghijauan, embung, lingkungan, Belu-NTT.

Abstract

District, East Nusa Tenggara Province. However, some wells in this area need to be conserved by planting of selected species at the watershed area in order the water available continually during a year. To understand the native and crop species that suitable to plant conservation the survey at the watershed of ‘Wetihu’, Baudaok-Belu was conducted in 2008. Aim of survey was to inventory the species and to understand land suitability based on its soil fertility and microclimate condition. Watershed landscape of ‘Wetihu’ in Baudaok Village, Belu District are characterized by rolling to hilly altitude,coral reef and limestone of soil material and the low soil fertility. Micro-climate in thisarea resulted the marginal land watershed and due to this problem the crop almost can not be planted by the local people. The observation by the distance of 1.5 km from ‘Baudaok’ well to the southern was found 39 wild and crop species. Some species which are able to adapt to the drought ecosystem and has potential to plant as economic crops are recommended to be selected, i.e.: the main food (Zea mays, Cajanus cajan), fruits (Musa paradisiaca, Mangifera indica), cattle feeding (Leucaene leucocephala, Sesbania grandiflora), handmade material (Bambusa sp.), fire wood, wind break trees and covercrops (Zizyphus mauritiana, Alstonia scholaris, Erythrina orientalis, Gmelina arborea,Schleichera oleosa), perfume oil producer (Santalum album).Key Words: native species, crops, watershed, conservation, Belu, East NusaTenggara Province

Abstract

Conservation of flora, soil and water resources are very important to manage‘embung’ ecosystem, in West Timor Island. Generally, ‘embung’ watersheds in this area are degraded, and consequently resulted high runoff and erosion rate; and at the same time, ‘embung’ water has not been used efficiently yet. To conserve ‘embung’ ecosystem, three methods can be applied, i.e.: 1). Flora conservation by using priority of local species; 2). Soil conservation by usingvegetative methods; and 3). Water resources conservation in watershed area by combining flora and soil conservation; and increasing water used efficiency by using intermediate technology.
