Abstract

Solid waste is one of the potential problems in Bali Province. One of the waste sources in urban areas especially Denpasar is the office and hotel/inn/guesthouse. Werdhapura Village Center is one of the office and hotel areas in Denpasar. Werdhapura management does not have an integrated waste management. Therefore, it should be made an integrated waste management plan started by doing study about waste generation and composition. The purpose of this study is to investigate the generation and waste composition in Werdhapura and estimate the potential amount of waste that can be managed. The study starts from surveys and interviews regarding the waste sources and existing condition of waste management in Werdhapura. The surveys conducted by reviewing the trash facilities, waste temporary site, and the sources of waste, while the interviews conducted to Werdhapura Management. Waste generation and composition measured by using SNI 19-3964-1995 method. The result showed that waste generation is about 4.6 m/day of volume, and about 302.3 kg/day of weight. Waste composition (%weight) the most is food waste (26.43%), paper (18.55%), residue  (14.64%), and organic waste (10.93%). About 47.51% of total waste in Werdhapura was potentially to recycle that is organic waste, food waste, and dry waste.

Abstract

Co-composting was the composting process uses two or more raw materials to improve the optimization process and material benefits. The purpose of this study was to determine the influence of the initial C/N value ratio and the active aeration usage of the co-composting process of filter cake and boiler ash of cane sugar industry. Co-composting  was done in the aeration pile reactor with 5 kg of mixed material,and uused two factor; initial C/N ratio and aeration. The treatment of  C/N ratio was begun at 30, 40, and 50 from formulation filtercake and boiler ash.   Active aeration was given at 0.4 and 1.2 l /minutes.kg materials that carried out for 1 hour per day  on the first week. From this observation, known that the aeration distiction at 0.4 and 1.2 l /minutes.kg materials does not effect the C/N ratio of  compost.  In the other hand,  the treatment of initial C/N ratio at 30 and 40 was significantly affected with initial C/N ratio at 50 compared by final  C/N value of the compost. Initial C /N ratio at 50 requested the final  C / N ratio of compost at 19-20 that was higher than the treatment of  intial C/N ratio at 30 and 40 which had final C/N ratio at 13-15 and 12-17, respectively.

Abstract

Bali has many rivers with river water discharge conditions is quite large and a lot of wasted at the mouth of the river in vain , because not all of the water used for agricultural needs and raw water . Current physical land in the mouth of the river has begun to change from agricultural land into building that support tourism in Bali This is in line with the development of tourism industry of small -scale tourism and large -scale tourism . In line with this condition, the problem is how the characteristics of the river mouth in Bali with the change in land use in the mouth of the river and how water resources management methods that go into the mouth of the river so that water resources be sustainably. Researchmethods that will be used is phenomenology . This is in accordance with the principle of preservation of objects that many studies related to water resources management system . The research process consists of two stages . Results obtained in the form of characteristics of the river , the river mouth morphology after land use change around the mouth of the river, based on secondary data ( reports of Bali Provincial Department of Public Works ) andresearch in the field ( primary data ) , this study uses the software as a tool of analysis . Karakteristik morphology Sowan estuaries ( Perancak and vicinity ) is influenced by the tide .

Abstract

Water availability is a major limiting factor to the growth and yield of rainfed rice.  Systemof Rice Intensification (SRI), which is an efficient method of planting rice, particularly inthe use of water, number of seeds per hill and time of transplanting seedlings, has beenapplied generally in irrigated rice but it is rarely practiced in rainfed rice.A field experiment, which was aimed to study the effect of number of seed/hill and variationof plant spacing on the growth and yields of rainfed rice with SRI (System of RiceIntensification), was conducted during dry season from April until September 2012. Thelocation was at Patemon Village, District of Seririt, Buleleng Regency, Bali, at the altitudeof 100 meter asl. In this experiment a completely randomized block design was used and thetreatment were arranged factorially. The first factor was the number of seeds (1,2,3 and 4)/hill and the second one was the plant spacing (20 cm x 20 cm, 25 cm x 25 cm and 30 cm x 30cm). All treatments were replicated three times.The results of the experiment showed that the interaction between one seed/hill and plantspacing of 30 cm x 30 cm resulted in significantly (P<0.05 and P<0.01)  the highest fresh(4.387 ton/ha) and oven dry weight of grains (3.633 ton/ha), oven dry weight of 1000grains (20.920 g) and the harvest index (31.163%). The gross margin analysis indicatedthat the variable costs were higher than the gross income for all treatment, due to high costof watering

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

This study aims at knowing: 1) the skill of the young generation in cultivating traditional medical plantation for children’s disease, 2) the implication of the first goal towards ecolinguistics. The setting of the study was in Bali province, consisting of 8 regencies and one city government, with the total of samples of young generation 360 and the sample of healers 45 individuals. The samples were determined by using purposive quota sampling technique. Thedata about the skill were collected observation, and the data about the implication the first goal were collected through interview. The result of the study shows that: 1) the skill of the young generation in cultivating traditionalmedical plantation was totally 58.5%, and partially there were young generations who could cultivate traditional medical plantation, such as Karangasem 73.12 (good), Klungkung 70.50 (good), and Bangli 71.36 (good), 2) the implication of   the first goal to eco-linguistics is that the young generations having better ability in cultivating medical plantation are more familiar with the medical plantation terms, though the physical representation of the plant is not definitelyknown. In this case, the skill in cultivating traditional plantation and the synergy among the related components are needed to increase for the maintenance of the medical plantation terms and environmental preservation.

Abstract

Sustainable development is a must for Bali. It is due to the fact that one of the negative impact of development is the change of the land use from agriculture into other functions. As a result most of medicinal plants will be extinct. In another hand there is a trend of people to plant horticultures in their house yards. The main issue: is there any relationship between horticulture and sustainable development? In answering it, a field study was conducted in Petiga Village, Tabanan, Bali Province. Observation and  interview were carried out to respondents consisted of five Balinese farmers who nurse cultivate the horticultural plants for their daily activities. Results show that: 1) there are about 159kinds of plant totally used as horticultural plants; 2) amongst those plants, about 67 plants belong to the medicinal plants and 80 plants belong to ceremonial plants; 3) number of horticultural plants in every house sampled ranged from 63-94 kinds; 4) the popularity of any horticultural plant is affected by the market’s demand. The conclusion which could be drawn is that the medicinal plants as well as the ceremonial plants are used for horticultural plants. It is due to their wonderful colors, nice stems, flowers or leaves, special odors, economical values and magical values as well. Horticulture could be used as a strategy for preservation and conservation program of the medicinal plants in Bali. It is recommended that for the sustainability, all medicinal plants which exist in Bali should be invented and planted in a form of medicinal plant park.
