Abstract

Pada saat ini energi listrik merupakan kebutuhan yang penting di Indonesia. Akibat pertumbuhan penduduk yang tinggi, kebutuhan listrik rakyat Indonesia akan bertambah 7 – 9% setiap tahunnya. Pada tahun 2010 rasio elektrifikasi secara nasional adalah 65% sedangkan diJawa Barat mencapai 69,9%. Energi listrik tidak hanya digunakan untuk penerangan tetapi juga untuk menjalankan aktivitas mata pencaharian. Tidak hanya daerah perkotaan, tetapi masyarakat pedesaan yang tinggal di daerah pegunungan juga membutuhkan energi listrik. Wilayah pegunungan biasanya mempunyai kemiringan lereng yang terjal dengan sungaisungai yang mengalir sepanjang waktu. Kondisi tersebut berpotensi untuk dikembangkannya pembangkit listrik mikrohidro (PLTHM). Tujuan penelitian ini adalah mengidentifikasi potensisumberdaya air DAS Cisadane Hulu untuk pengembangan pembangkit listrik tenaga mikro hidro. Penelitian ini mengunakan aplikasi hidrologi model Soil and Water Assesment Tools (SWAT) yang mengkalkulasi hujan sebagai input dan diproses pada sistem DAS yang kemudianoutput model berupa debit, loading sediment dan kualitas air. Dengan model hidrologi yang tervalidasi didapat luaran debit yang kemudian dianalisis untuk mencari debit andalan 80%. Hasil simulasi model dan analisis debit andalan menunjukan DAS Cisadane Hulu mempunyaibanyak potensi energi listrik yang dibangkitkan dengan PLTMH, dua SubDAS klasifikasi PLTA skala kecil, yaitu; SubDAS di Desa Cisarua dengan debit andalan 5,63 m3/detik dan beda tinggi 67 m berpotensi menghasilkan 3.511 kW, kebutuhan volume reservoir sebanyak 22,8 x 106 m3 dan SubDAS di Desa Bantarkaret dengan debit andalan 3,85 m3/detik dan beda tinggi mencapai 39 m berpotensi menghasilkan energi listrik sebesar 1.398,6 kW dengan kebutuhan tampungan air sebesar 9,3 x 106 m3. Sedangkan SubDAS lainnya masuk dalam klasifikasi minihidro (100 kW – 1000 kW).

Abstract

Kualitas ekosistem kota dipengaruhi oleh ketersediaan kanopi pohon dalam RTH kota karena selain fungsi estetika dan visualnya, pohon mempunyai beberapa fungsi bio-ekologis yaitu modifikasi radiasi matahari, mengurangi kebisingan, penyaring dan penjerab polutan, pencegah erosi dan pengontrol laju limpasan permukan; serta fungsi sosial ekonomi dan budaya. Walaupun demikian besarnya manfaat lahan bervegetasi, namun keberadaannya sulit dipertahankan saat dihadapkan pada konflik kepentingan alih fungsi lahan, dikarenakan  masih minimnya pemahaman masyarakat dan pihak pengelola kota dalam menterjemahkan nilai ekonomi RTH kota, serta keterbatasan alat analisis (tools) yang mampu menterjemahkan sejumlah nilai manfaat tersebut ke dalam bentuk angka-angka nominal (nilai ekonomi) yang lebih mudah dipahami oleh semua pihak. Sebuah organisasi Non Profit US Forest mempelopori pendekatan cost-benefit analysis ini dengan mengembangkan sebuah program analisis berbasis GIS untuk menghitung manfaat ekonomi hutan kota secara spasial, dengan menggunakan bantuan perangkat lunak software Arcview 3.2. ektensi CITYGreen 5.4. Aplikasi program ini dilakukan dalam serangkaian  penelitian di wilayah administratif kota Bogor. Berdasarkan hasil analisis yang telah dilakukan, maka penggunaan program aplikasi CITYGreen ini dapat digunakan untuk menganalisis potensi RTH untuk 4 manfaat, yaitu: potensi penyimpanan dan penjerapan Carbon, potensi reduksi limpasan permukaan,  konservasi energi, landcover breakdown dan pemodelan pertumbuhan pohon. Hasil analisis berupa peta landcover, dan analysis report yang menyajikan: site statistic,  ecological benefits, dan economic benefit summary/nilai nominal manfaat ekosistem untuk 4 kategori tersebut, yang diharapkan dapat menjadi bahan pertimbangan penyusunan kebijakan strategis pengelolaan RTH kota. Kata kunci : CityGreen, RTH, Ekosistem kota

Abstract

Way Betung watershed is one of the important water resources in Lampung Province and it provides a clean water for Bandar Lampung City through a regional water supply company (PDAM). By the increase of population and economical activities of Bandar Lampung City, the need of clean water also increase, however by the time, the conditions of Way Betung watershed as water resources are declining. Therefore, to improve or to restore WayBetung watershed, a high cost is needed. The research was aimed: (a) to study the effects of Way Betung watershed land use change on the water resources of Bandar Lampung City, (b) to arrange the sustainable development of Way Betung watershed in order to maintain the availability of water resources. The sustainable developments of water resources of Way Betung watershed were arranged in five alternatives/scenarios and each alternative was related toits erosion (USLE method) and its run off volume (SCS method). The results showed that land use changes of Way Betung watershed (1991-2006) were likely to increase daily maximum discharge (Q max), to decrease daily minimum discharge (Q min), to increase fluctuation of river discharge, and to increase yearly run off coeffcient. The best sustainable development of water resources of Way Betung watershed, Lampung Province, was alternative/scenario-4 (forest as 30% of watershed areas + alley cropping in the mix garden). This alternative will decrease erosion to the level lower than tolerable soil loss and also decrease fluctuation of monthly run off.Keywords: Land use change, run off coefficient, water resources, watershed

Abstract

Crop and management factor value is significantly corelated with outputs of ANSWERS model especially on soil erosion.   Using daily crop and management factors (daily C factors), the ANSWERS model performs well in predicting soil erosion which is showed by determination coeffient (R2 = 0.89), model efficiency (0.86), and average of percentage model deviations (24.1 %).  Whereas using USLE C factor (2 cropping systems), predicted is much higher than measured soil erosion (over estimate).  Output of the model is not statisfy, it is represented by model coefficient (0.40) and average of percentage model deviations (63.6 %).

Abstract

ABSTRACT Phenomena of depleting of water resources and increasing water demand have been occurring in Konaweha watershed. Combine with other conditions, Konaweha watershed have been categorized as priority watershed in Southeast Sulawesi Province. Land use change is  presumed to  influence hydrology conditions such as  the  increasing maximum discharge in rainy season, decreasing minimum discharge in dry season and also runoff coefficient increased in rainy season. The objective of this research was to evaluate the effects of land use changes on hydrology conditions such as maximum discharge, minimum discharge and runoff cpeficient. This research was conducted at Konaweha watershed for 10 months from June 2009 to March 2010.   The result of this research showed that forest, swamp,  plantation  and  bush  area  tended  to  decline  exponentially year  by  year  due  to population growth. During 1991 to 2010 forest decresed from 66,6 % in 1991 to 48,3 % in 2010. At the same time, plantation, mix garden and bush increased 26,0 % to 39,7 %, 3,0 % to 5,0 %, and 1,7 % to 3,1 % from the total of the watershed area.   The decline of forest area have significantly decreased minimum discharge of Konaweha River in dry season from 40 m3/second in 1991 to 24 m3/second in 2010. At the same time, maximum discharge increased from 246 m3/second to 284 m3/second, and runoff coefficient increased from 31,4% to 48,3 %. Key words: watershed, land use change, discharge, runoff coeficient

Abstract

The objective of this research was to evaluate and assess the level of run-off  and erosion on various types of land use in the Upper Jenneberang Sub Watershed. This research was conducted in the Upper Jenneberang Sub Watershed, Saluttoa Village, Sub Tinggimoncong, Gowa regency, South Sulawesi Province. Land use type (LUT) which was used as land units of observations was determined based on land use maps of upper Jenneberang sub watershed. Based on the analysis results of map and observation in the field, it was defined four types of land use as land units of observation: 1) Natural forest, 2) Gliricidia tree-dominated agroforestry, 3) Coffee tree-dominated agroforestry, and 4) Maize monoculture. Each LUT was given the observation plot size 30 m x 10 m and plot placement was determined randomly. All LUT had slope 26%, soil type of Brown Latosol at the same altitude and climate. The composition of the observation plot was based on Randomized Block Design (RBD). Collected data on LUT included: soil physical properties, infiltration rate, run-off and erosion. The result showed that changes in land use of natural forests into agroforestry and maize monoculture types resulted in decreased amount of woody vegetation that resulted in increased run-off and erosion. Keywords : run-off, erosion, agroforestry

Abstract

Land degradation is a serious problem in the Upper Sekampung Watersheds.  This is because the farmers cultivated in steep land to coffee crops without  in adequate soil and water conservation practices.   The land degradation is mostly caused by erosion.  The erosion problem not only stripping the most fertile top soil and decreasing crop production, but also resulting problems in lowland.  Therefore, the reorientation land management should be improved to produce agriculture sustainability. The first step is to evaluated land capability this area.  The objectives of the research were evaluate land capability of Upper Sekampung Watersheds.  The results showed that the Upper Sekampung Watersheds were dominated with class and subclass land capability of III-l2 about 17.630,51 ha (41,58 %). All of the constrain for each land capability in this area is erosion hazard, especially land slope.  From this research, cultivated land to coffee base crops were allowed in land capability II-l1.e1, III-l2, IV-l3, and VI-l4, with in adequate soil and water conservation practices. In contrary, the land capability of VII-l5 unsuitable for agriculture, they should be a nature or for conservation forest.

Abstract

Forest conversion to some land use happened in all watershed, includes Batang Pelepat watershed. The objectives of this research are to know effect of forest conversion to land of rubber (Hevea brasiliensis) and palm oil (Elaeis guinensis Jack) farming on run off and soil erosion and different of erosion rate on agro technology of rubber and palm oil farming in Batang Pelepat watershed. The research was carried out during 3 months, begin October to December 2006. Run off and soil erosion measured plot with gutter in the lower of plot. Experimental design for this research is randomized complete block design, with land use type as treatment and slope class as replication or block. Data analyzed statistically by variance analysis (F-test) and Duncan New Multiple Range Test on confidence 95% (α = 0.05). The results of this research show that area of forest coverage in Batang Pelepat watershed was decreasing. In 1986 this area still 94,50% of watershed area, but in 1994 area of forest only 78,17% and in 2006 forest area 64,20% of watershed area. Forest conversion was carried out to land of rubber and palm oil farming with some actual agro technologies. Land of monoculture rubber I resulted the highest run off and soil erosion more than the other land use type and showed different of run off and soil erosion on land of secondary forest.
