Abstract

School yards are a part of a few green open areas in urban environment. Therefore, school yard has important role for urban ecosystem. The goal of this research is to compare bioecological condition among elementary, middle and high schools and analyse the level of relationship among bioecological aspects, students and teachers preferencies toward their school yards. We have conducted research in 2008 which involved 20 elementary, 8 middle and 8 high schools at Denpasar Bali. Those schools were devided to be two groups: A (we observed their shool yards and have taken survey for students and teachers) and B (only taken survey to students and teachers). Results showed that percentage of oppened yard toward total areas of elementary school (46,5±17,1%) higher than middle school (38,8 ±15,5%) and high school (37,5±9,6%). Also the proportion of school garden in elementary school (30,2±20,3%) nearly twice higher than middle school (18,8± 6,3%) and high school (20,0±8,2%). Environmental preferencies of majority sample (>80%) were higher than point 4 of 7 Likert scales. Its mean, they tend to give positive image both artistic (beautiful, green, fresh, healty, happy and wide) and the ecological roles of school yard (rain water catchment, pollution absorbtion, animal habitat, oxygen supply, opennes toward sunlight and plant biodiversity). While plot of factor analysis showed that bioecological scores located in the same field with environmental preferencies of samples from group B. Thus the model of integration between environmental preferencies and bioecological evaluation able to give a new perspective of school yard as a socio-natural unit. Its not only important for ecosystem but also for human well-being. Thus we suggested to apply socio-natural approaches, mainly through enggaging non-owner communities in rating certain of the urban ecosistem.

Abstract

Ringkasan Eksekutif Petani Subak Bengkel Sari Tabanan, tidak pernah menanam jagung, hanya menanam padi secara monokultur. Pada musim kemarau sebagian besar lahan dibiarkan kosong akibat ketersediaan air irigasi yang tidak mencukupi untuk menanam padi. Padahal, dengan ketersediaan air irigasi yang terbatas tanaman jagung dapat tumbuh normal. Oleh karena, tanaman jagung sangat adaptif terhadap ketersediaan air irigasi yang terbatas dan bahkan dapat hidup normal dan berproduksi maksimal dengan hanya mengandalkan air hujan. Menanam padi secara monokultur tanpa ada pergiliran tanaman menyebabkan menurunnya kesuburan tanah dan siklus hama tidak terputus serta pemanfaatan lahan tidak optimal yang berakibat tidak ada peningkatan pendapatan. Untuk itu, petani perlu diberdayakan dengan melakukan introduksi teknologi budidaya jagung dan efisiensi penggunaan pupuk kimia serta pendampingan dalam memanfaatkan lahanya pada musim kemarau. Program demplot seluas 10 are ini terinspirasi dari potensi lahan kondisi geografi lahan dan iklim yang menunjang untuk pengembangan jagung. Untuk berhasilnya program demplot, dipilih petani yang mempunyai komitmen kuat yang diketahui melalui wawancara. Kegiatan demplot diawali dengan penyuluhan dan dilanjutkan dengan praktek menanam, penanganan pasca panen serta pemasaran. Jarak tanam yang digunakan yaitu 70 x 20 cm dengan satu tanaman per lubang, bibit yang dipilih adalah varietas hibrida BISI-2. Dalam pemeliharaan tanaman, penggunaan pupuk kimia hanya 50% dari dosis anjuran dan sebagai kompensasinya digunakan pupuk organik kotoran sapi. Guna memperoleh data berat biji pipilan kering kadar air 12% ditentukan dengan menggunakan Moisture Grain Tester tipe PM-140. Hasil biji pipilan kering dari ubinan seluas 1,68 m2 dikonversi ke hektar guna memperoleh data produksi per hektar. Kelayakan usaha tani jagung dianalisis secara sederhana untuk melihat keuntungan yang diperoleh dibandingkan dengan usaha tani padi. Produksi biji pipilan kering yang diperoleh sebesar 7,8 t ha-1. Produksi ini lebih rendah dari demplot di Subak Cau Belayu (8,5 t ha-1) dan lebih rendah dari potensi hasil varietas BISI-2 yaitu 13 t ha-1. Hasil yang lebih rendah ini disebabkan oleh derajat keasaman tanah tinggi cukup tinggi antara 4 – 5. Selain itu, hasil yang rendah juga disebabkan oleh adanya serangan hama tikus saat pengisian biji. Namun demikian, usaha tani jagung masih menguntungkan walau tidak sebesar usaha tani padi. Keuntungan yang diperoleh untuk luasan satu hektar sebesar Rp. 8.125.500. Melihat dari produksi dan keuntungan yang diporoleh, maka lahan sawah di Subak Bengkel Sari potensial untuk pengembangan jagung hibrida BISI-2. Program demplot telah berdampak  terhadap kelompok tani sasaran yaitu terjadi peningkatan pengetahuan dan keterampilan dalam budidaya jagung. Petani lain di luar kelompok sasaran tertarik untuk pengembangan jagung, karena keuntungan yang diperoleh cukup tinggi. Program ini telah memberikan manfaat yaitu membuka wawasan petani tentang usaha tani alternatif pada musim kemarau, sebagai bentuk optimalisasi penggunaan lahan. Program ini juga memberikan manfaat terhadap perluasan areal tanam, sehingga terbentuk sentra-sentra produksi jagung yang baru. Kata-kata kunci: Optimalisasi lahan, efisiensi pupuk, jarak tanam, varietas BISI-2 Executive Summary The farmers of Subak Bengkel Sari, Tabanan Regency never plant corn, just planting rice in monoculture. In the dry season most of the land is left vacant due to the availability of irrigation water is insufficient for growing rice. In fact, with the limited availability of irrigation water corn plants can grow normally. Therefore, corn plants are very adaptive to the limited availability of irrigation water and may even live a normal and reach maximum production by simply relying on rain water. Planting rice in monoculture without crop rotation due to declining soil fertility and pest cycles are not interrupted and is not optimal utilization of land resulting in no increase in revenue. For this, farmers need to be empowered by the introduction of maize cultivation technology and the efficient use of chemical fertilizers as well as assistance in utilizing land in the dry season. The program area of 10 acre demonstration plot was inspired by the potential field of land geography and climate conditions that support for the development of corn. Demonstration For successful demplot programs farmers who have a strong commitment were selected through interviews. Demplot activity began with the extension and continued with planting practices, post harvest handling and marketing. Spacing used is 70 x 20 cm with one plant per hole, the selected seed is a hybrid variety BISI-2. In plant breeding, use of chemical fertilizers only 50% of recommended doses and compensatory use of organic fertilizer cow feces. To obtain dry weight seed moisture content 12% was determined using Grain Moisture Tester type PM-140. Seed dry yield of tile area of 1.68 m2 converted into hectares in order to obtain data on production per hectare. Analyzed the feasibility of farming corn is simply to see the benefits compared to rice farming. Production of dry seed obtained at 7.8 t ha-1. Production was lower than in demplot Subak Cau Belayu (8.5 t ha-1) and lower than the yield potential of varieties BISI-2 at 13 t ha-1. Lower results were due to high soil acidity valued from 4 to 5. In addition, the low yield is also caused by rat infestation during grain filling. However, maize farming was still profitable, though not for rice farming. Gains were derived by an area of one hectare of Rp. 8.1255 million. Viewing of production and profits, the wetland in Subak Bengkel Sari had a potential for the development of hybrid corn BISI-2. Demonstration plot program has an impact on the target farmer groups namely an increase in knowledge and skills in the cultivation of corn. Other farmers outside the target group were also interested in development of corn, because the profits were quite high. This program had benefits to farmers by opening insights about alternative farming in the dry season, as a form of optimization of land use. This program also provided benefits to the expansion of planting area, so that the centers formed a new production of corn. Keywords: land optimization, fertilizers efficiency, line spacing, varieties BISI-2

Abstract

The presence of local floral resources as forage is essential, especially for the farm survival in anticipaty the impact of the global climate change. The availability of forage in the dry land ecosystems depends on water supply. However, the climate change has caused the change on rainfall pattern including the initiation of the dry season. The problem should be anticipated by the local farmers’ readiness in providing sufficient feed and their ability in performing the excellent management during all seasons. In some areas of East Bali and Nusa Tenggara (West andEast), dry climate crisis 2004 led to feed scarcity. Therefore, this study was conducted in order to identify the potential forage resources in the arid land. The discussion is focused on the results of survey and secondary data collection. Based on the results, there were 22 plants that could be used as forage which were abundant during rainy season, whereas 15 others were able to be forage and silage during the transitional season and along the dry season. The results also showed that the introduction of silage fermentation technique was required as the way to preserve feed for the supply during the dry season. In this study the role of polymer compounds hydrolyzing microbes and the fermentation process by the GRAS (Generally Recognized as Safe) microbes preceeded the role of Lactobacillus plantarum were observed. The results of this study may become a reference in anticipating the global climate change impacts in dry land areas by the application of functional microbial technology in small local farms’ feed management activities.(Key words: Local floral resources, Dry land climate, Fermented feed, Lactobacillus plantarum)

Abstract

Large amount of palm mill effluent is generated annually. The waste would be potential for production of single cell oils (SCOs). The objective of study was to evaluate the lipid accumulation by fungi using palm mill effluent as substrate. To obtain most potential strains for lipid accumulation, seven filamentous fungi isolated from various biomes were evaluated for their ability to produce endoglucanase, and its lipid accumulation. Fungal hypae grown on palm oil mill effluent accumulated lipid of 34,3-87,5 of their dry cell mass. The profile of transesterified SCOs revealed a high content of saturated and monounsaturated fatty acids i.e., palmitic (C16:0), stearic (C18:0) and oleic (C18:1) acids similar to conventional vegetable oils used for biodiesel production. The strain was able to use organic substrates in POME implies that they are promising strain for biofuel feed stock as well as for meeting effluent quality for wastewater discharge.
