Abstract

The research entitled “ Developping drought resistance of corn variety via evaluation of SMCT-2 line ” which aimed to achieve of agronomic characteristic varians and yield potential of SMCT-2 compare with SMCT-1 line and their parent. This research considered to conduct at dry season in Denpasar about 2007 and 2008. Selection method on this research is purporsive random sampling. Evaluation of variance selection line (SMCT-2) compare to parent showed significant different (F= 0,05) of some variables such as total of leafs, plants hight, leafs area, internodes, diameter of stems, position of ears corn, silks period, grains line on ears, ears length, grains weight per plant, weight of 100 grains per plant. Non-significant variance of variables is: length of internode, ears corn diameter, dry weight of raw materials, total of productive ears corn, initial period of tassels. Variances of entire variables of SMCT-2 relatively are lower than parent and SMCT-1 line. The higher variances of SMCT-2 are showed on height of plants (526,30) , leafs area (4011,10), position of ears-corn (205,58), dry weight of raw materials (5641,37), dry weight of ears-corn per plant (188,82), total of grains per plant (4335,26), dry weight of grains per plant (276,58). Coerffient of variance showed that SMCT-2 line, SMCT-1 line and parent less than 20 %. Average of variables to support production SMCT-2 line yields are relatively higher than parent is showed by: length of ears corn (13,20 %), dry weight of ears corn (5,6 %), total of grains per ear-corn (15,23 %), lines number of seeds per ear corn (4,80 %), dry weight of grains per plant (27,61 %), dry weight 100 grains per plant (3,33 %). Dry weight of yield SMCT-2 line was founded 5,02 ton per hectar, which is higher 4,58 % than SMCT-1 (4,8 ton per hectare), and is higher 8,71 % than parent (3,9 ton per hectare), with population 50.000 plants per hectare. This line was relative resistance on drought, show that was devolved to produced new variety for the arids areas.

Abstract

Metana adalah gas alam yang dilepaskan ke atmosfir oleh proses biologi yang terjadi pada lingkungan anaerobik melalui proses metanogenesis. Metana mempunyai kekuatan  21 kali lebih besar terhadap kenaikan suhu dibandingkan COdalam periode waktu 100 tahun.Landfill adalah sumber kegiatan manusia terbesar yang menghasilkan metana. Salah satu cara yang sederhana dan murah untuk mengurangi gas metana dari landfill yang lepas ke alam  adalah dengan mengoksidasi metana dengan memanfaatkan tanah penutup landfill sebagai media mikroorganisma pengoksidasi metana, sehingga dapat mengurangi kontribusi metana pada pemanasan global. Tujuan penelitian yaitu untuk mengidentifikasi empat jenis sampah lama (kompos landfill mining)dari beberapa TPA di Kota dan Kabupaten Bandung sebagai alternatif untuk tanah penutup landfill yang dapat mendukung oksidasi metana.Sampel yang akandiidentifikasi  adalah sampah lama dari 4 (empat) TPA (Tempat Pemrosesan Akhir Sampah) yaitu TPA Jelekong, TPA Pasir Impun , TPA Leuwi Gajah  dan TPA Sarimukti. Hasil identifikasimenunjukkan bahwa sampah lama dari keempat TPA mempunyai karakteristik untuk dapat menjadi alternatif  tanah penutup landfill sebagai media yang mendukung oksidasi metana dan sampah lama dari TPA Jelekong mempunyai potensi oksidasi yang lebih besar dibandingkan  dari TPA lainnya

Abstract

Shifting cultivation is cultivation system performed alternately from one field to another on forest lands. This study aims to assess changes in structure and composition of vegetation and determine the conditions of environmental factors during shifting period. This research use chronosequence approach at sites with different ages i.e. two, four, six and eight years compared to natural forest using structured form squares (20x100 m2) belt transect comprising several terraced plots. Vegetation parameters were measured for all forms, environmental factors measured were microclimates and edafic factors and soil macro-nutrient content. The results showed that 42 species of 23 families founded in all forms. The vegetation distribution from diameter classes (KD) indicated that KD 0-10 cm had the highest number of individual density from all research site and declined sharply with the increase of KD. The potential regeneration of tree species vegetation component of each site showed some different patterns. In aspect of microclimates, the temperature decreases along with sites age. Edafic factor did not show any clear pattern with increase of sites age for C, N and P, while soil K levels were significantly higher in the youngest site age than the older sites.

Abstract

Studi anatomi dilakukan untuk mengetahui karakteristik epidermis daun pada 13 kultivar salak Bali. Hasil penelitian ini menunjukan bentuk sel pada bagian permukaan atas (adaksial) dan permukaan bawah (abaksial) daun salak Bali adalah persegi empat sampai jajaran genjang. Sedangkan dinding antiklinal sel epidermisnya berlekuk-lekuk dengan penebalan pada dinding tersebut. Semua kultivar yang diamati memperlihatkan tipe daun yang hipostomatik dimana stomata hanya dijumpai pada bagian abaksial daun. Walaupun demikian stomata terkadang dapat dijumpai pada bagian adaksial daun meski jumlahnya sangat sedikit. Tipe stomata pada daun salak bali adalah parasitik dimana tiap sel penutup didampingi oleh satu atau lebih sel tetangga yang letaknya sejajar dengan stomata, dengan penebalan pada dinding sel penutupnya. Indeks stomata bervariasi antara 11.9% sampai 18.3% pada semua kultivar yang diamati.

Abstract

This research was performed to study the characteristic of acid sulphate  agricultural soil. Since “pasang surut” area are very potensial to be used for agriculture, it advantages and disadvantages has to be investigated based on mineral exchange and chemical characteristic due to oxidation and reduction processes. This research was using completely randomized design ; soil was collected from agricultural area using pots before these pots were then randomly mounted in glass house. This soil then analysed in Laboratory to find out its characteristics such as clay mineral and chemical characteristics of the soil. These analysis were performed twice, i.e. before reduction-oxidation and after reduction-oxidation process. Data than statistically analysed in semi quantitative and qualitative before descriptive interpretations. Results from this analysis indicated that; (1) Reduction-oxidation processes applied to the acid sulfat soil do not change the kind of mineral contained in the soil whether montmorilonit, illit, kaolinit, goethit, or quart; (2) Soil being reduce for 2 months underwent chemical changes such as, soil pH increased form 5 to 5.30, al-dd content were decreased from 7.81 me/100g into 5.35 me/100g, iron ferro was increased from 41.14 ppm into 284.32 ppm, but ferric iron was decreased from 424.73 ppm into 185.79 ppm, the amount of soluble sulphate was decreased from 436.18 ppm into 240.74 ppm; (3) After it was oxidized for two months, chemical characteristic of the soil was changed, soil pH was changed from 5.00 into 4.26, Al-dd was increased from 7.81 me/100g into 20.42 me/100g, ferro iron content was decreased from 51.14 ppm into 21.59 ppm, by contrast, ferric iron content was increased from 424.73 ppm into 448.52 ppm, soluble sulphate was increased from 384.64 ppm into 436.18 ppm.

Abstract

A study on birds has been conducted in Nusa Dua Tourist Resort area, Bali, betweenJanuary, 1999 and January, 2002. In this study, bird species was identified and theirpotentials for ecotourism-bird watching activities were analysed. From the field observationit was found that the site has a potential to be developed as a bird watching site. It can beseen from the diversity of bird species identified there, especially in the lagoon. In Nusa DuaTourist Resort area 83 bird species has been identified which is representing over 27% ofbird species on Bali. About 87% of those were classified as non-migrant species, while therest were migrant. Among those species, 6% were birds which were known to be restrictedtheir distribution to Indonesia. The strategic location of Nusa Dua Tourist Resort area alsoincreases its potential for development of bird watching activities. For development of theseactivities, holistic management approaches need to be implemented, the approaches of whichneed considering a balance between conservation, economic and empowerment of localcommunity objectives.

Abstract

The study area consists of 2 (two) landforms, the hill and the ridge. The hill and the ridge  withslope varied have different rock composition, such as igneous and metamorphic rocks. Besidesthat the landcover of the two landforms also has different variety. These characteristics areexpected to affect the rate of erosion. The purpose of this study were (i) To analyze thecharacteristics of the land parameter from both landforms with different rock units, as thefactors that influence the differences in the level of erosion (ii) To determine the difference ofthe rate of erosion at the igneous and metamorphic bed rocks.Research methodology that have done were survey and mapping. The level of erosion isknown from the results of direct measurements by the method of small plots on each land unit.The survey results revealed that the rate of erosion on the rock units schist (metamorphicrocks) is greater than the unit gabbro rock (igneous). Differences in the level of erosion isinfluenced by rock units, thick soil, slope, and land use.

Abstract

This article attempts to relate two important issues of regulating building height limit and sustainability of the natural environment. It is part of publications that document findings resulted from the so called fundamental research study, that was consecutively funded by the Indonesian Department of Education in 2008 and 2009. This study used hermeneutical research approach, which was observed through selective case studies. Within the last two decades, sustainability of our nature and life on earth have attracted a serious attention, not only from environmentalists, but also from economists, politicians, academics, as well as those who concern about socio-cultural development as a whole. In line with the intense environmental destruction\'s taking place in a speed which has never been anticipated, this aforementioned condition continues to require intensive actions. Architecture and regional planning, two disciplines that dedicate their focus of interests on building design and the management of spatial development, cannot turn their eyes away from such a world-widely spread phenomenon. Both disciplines utilize space – nature –, which consequently bring about impacts on the surrounding environment. In relation to local development, planning discipline especially, orients its activities toward developing various mechanisms in guiding and controlling development, as well as sanctioning violations of planning laws. Ideally, these attributes aim at balancing spatial need of numerous interests, mitigating potential negative impacts on the environments, and offering solutions in overcoming problems and conflicts. Contextualizing its discussions within the above circumstances, this article investigates three prominent topics of discussion. First, it examines the idea of development and sustainability. Second, it studies the implementation of sustainability to the context of spatial development. Third, it bridges the first and second sections with the issue of building height limit regulation at a global level. Before embarking on discussion over these three elements, this article draws an emphasis on the inextricable correlations between sustainable development, spatial development, and building height. Overall, this article critically summaries considerations and efforts in sustaining our life on earth by appropriately addressing considerations of either limiting or relaxing building height limit in a particular planned area.

Abstract

Energy management is very crucial now days due to the energy crisis and considering the emission produce by the activity. The production of energy releases large amount carbon emission to the environment, in addition the energy usage also produces carbon emission. Therefore, the unwise usage of energy leads to damage environment due to double amount of carbon emission. Application an energy management has an important role in reducing energy use in hotel particularly. Energy management in a hotel has produced a decision to apply a heat recovery system at their air condition system. It has significantly reduced oil consumption of the boiler from 772.274 litre/year to 158.472 litre/year that means a reduced on the carbon emission of 1.641.307 kg /year.
