Abstract

Waste is often viewed as a problem in human life. On one hand, waste is considered as having no economic value, thus disposed; on the other hand it is viewed as useful material. The purpose of this research was to develop a waste management system in Parepare. It was conducted in a region of 99.33 km2 consisting 21 villages. The location was determined on the basis of population density, resulting in the villages of: Wattang Soreang, Labukang, and Lumpue. The primary data was obtained from 100 respondents, and the secondary data from various related institutions. The respondent profile shows that 87.0 % respondents are males and 13.0 % females. In terms of education level, around 11.0 % respondents are of elementary schools, 23 % of junior secondary schools, 52 % of senior high schools, and 14.0 % of tertiary education. 64.0 % respondents are state civil servants and National Army, 15.0 % self-employed, 12.0 % farmers and fishermen, and 9.0 % laborers. At present, the waste management system is not optimal because of limited vehicles of waste removal, field workers, and waste collecting facilities, thus only as much as 256 m3/day .

Abstract

The traditional medicine still exists in Bali; it is supported by the fact that some plants are used for traditional drugs. Up now, the Balinese traditional medicine still functions. It is as an element of Balinese culture. As a consequence of development in general, there is a shift in land-use. It is assumed, that some of medicinal plants will exctinctive. It is a fact; the young generation is not familiar with the medicinal plants. Not all of the medicinal plants have been studied, its effect as well its active compound. Eventually, there is a trend in Balinese society, that they are favor of horticulture, by making use of medicinal plants. That is become a stepping stone for conservation of the medicinal plants. In relation to that, a walk-through survey was conducted in 20 households, 26 out of house yards, 10 governmental offices, 10 stars hotels, and five segments of median road in Denpasar. The goals are: to know the total number of horticultures planted, kind of the medicinal plants used as horticultures. The results found are as follows: 1) there are about 190 names of plants for horticultures; 2) many of the medicinal plants are used for the horticultures; 3) the horticultures are planted in house yards, out of house yards, government offices stars hotels and median road; 4) through horticultures some of the scarcely medicinal plants could be preserved. The conclusions could be drawn are: 1) the horticultures make use of local existing-medicinal plants; 2) for horticultures it is also imported from other islands; and 3) the horticultures could be used as a strategy for medicinal plants conservation in Bali. For further study the followings suggestions are addressed: a) all of the medicinal plants in Bali used for horticultures; b) more attempt must be focused on the existence of medicinal plants in Bali; c) the idea for establishing medicinal plants park in Bali, needs support from all stake holders, for natural resources conservation and preservation. The preserved medicinal plants will be good as an asset for education, tourism and social-cultural aspect as well.

Abstract

Intensive farming system development will lead to trade-off between economic benefits in the short run and environmental problems, especially critical soil erosion in the long run. The excessive erosion has reduced soil quality, then caused rapid reduction in land productivity or even made the land unsuitable for agriculture. If agriculture is to become sustainable, land management must be considered as one of best management practices in farming system development. A research in Tembok Village, Buleleng Regency, Bali aims to assess land suitability, soil fertility, soil erosion and conservation, and soil nutrient management for irrigated mixed farming system in north coastal plain of Bali. It is found that coastal area in the study area is classified into poor fertile soil due to the low level of cation exchangeable capacity and organic matter content. It is potentially categorized as marginal suitable (S3) for maize, cassava, groundnuts, sweet potato, melon, chili, banana, cashew, coconut, and palmyra palm; and suitable enough (S2) for mango, papaya and fodder grasses. The erosion level was very light by 2.036 t/ha/yr. This level has good relation with the erosion level by 2.04 t/ha/yr from laboratory experiment result by Sukartaatmadja et al. (2003) with similar characteristic of land and cow manure dosage requirement by 5 t/ha/yr. To improve soil fertility and to keep soil erosion not more than 2.036 t/ha/yr, the minimum 5 t/ha/yr of manure should be added into soil.

Abstract

Diesel fuel is widely used in manufacturing and transportation industries. Its production, transportation, use and disposal have the risk to contaminate the environment. In the other hand contaminated site usually can produce some microorganisms, through natural selection, that can utilize the hydrocarbons as source of energy and food thus clean the environment itself. For bioremediation purposes, 14 isolates of diesel oil degrading bacteria from Bandung, Jakarta, and Bali has been employed for diesel oil degradation. These 14 isolates, together with other variables, e.g. pH, Pb, sucrose and urea, were plotted in 23x24 matrixes of Plackett and Burman statistical method. Fermentation was carried out in batch cultures for 14 days. The results showed that 9 isolates and the availability of sucrose and higher initial pH have a positive/stimulatory effect on diesel oil biodegradation, 5 of which were very significant (99.99%), whereas 1 isolate has inhibitory effect (-98%). The results also revealed that 8 isolates, higher initial pH, and availability of urea have stimulatory effect on culture growth (more than 90% significant). The present of Pb in medium inhibit both growth and the degradation of diesel oil, although the effect was not significant (less than 60%).

Abstract

Bamboo during the time less get existence cause that assumed did not be important. This ascription cause that bamboo did not become the high economic valuable kommodity for society. During the time rehabilitations of the critical farm and forest area almost everything use the crop tree and next to nothing bamboo cultivation. Studies indicate that one hectare of bamboo crop can permeate more than 12 ton CO2 from the air. Bamboo also more effective in conservation irrigate where permeable bamboo 90% rainwater, while tree only 35 - 40%. Management and good bamboo crop can improve the society economics. Young bamboo can be used for the vegetable of bamboo bar and for the requirement of industrials, construction material, and crafts. If cycling enterpasing of bamboo forest during 20 year, hence total fund requirement reach the Rp 87.960.100,00 per ha with the acquirement [of] result of equal to Rp 767.520.000,00. Thereby the effort competent bamboo cultivation visible and profit.

Abstract

Environmental Management System (EMS) is very important in pursuing sustainable development. Problems were then arising, how to implement SML in the dimension of the Tri Hita Karana, Balinese life philosophy, so it is fit with Balinese life. Thus planning, doing, checking, actuating and controlling should be applied in the dimension of spiritual, socioeconomy (community) and environmental aspects, three aspects on the Tri Hita Karana philosophy. Because tourism is a major source of income for the Balinese it is then interesting to see how the EMS which adopt the THK philosophy being implemented in Bali. Many things can be learnt from its implementation on tourism sectors, especially on hotel businesses.

Abstract

The research of agroecosystem zone characteristics and land suitablities of south slope Batukaru Mountain, Tabanan Regency, Bali Province, was conducted. The aims of this research are to know the agroecosystem zone characteristics in toposequence of south slope Batukaru Mountain, their land suitablity classes, and limiting factors. This study was conducted through field survey by using zone or sub zone of agroecosystem as land unit in taking soil sample. Each of agrosystem zone or sub zone was observed and taken as the soil sample. The land characteristics were classified using the criteria of land characteristics classification in evaluating the land suitabilities. The land suitabilities, their potential, and limiting factors were analyzed using land suitability evaluation criteria. This study resulted in that south slope of Batukaru Mountain can be divided into 5 agroecosystem zones with various characteristics and land suitabilities. The main limiting factor in rice field was the lack of nitrogen, phosphate, and calium. On the other hand, in dried land, coconut farming, and coffee farming, the limiting factors were the lack of Nitrogen and the sloping land mainly in agroecosystem 3 and 4.
