Abstract

One of the recoverable coastal resources that can make a high contribution to the coastal environment and to coastal communities is the seagrass ecosystem. Seagrass is a flowering aquatic plant that has the ability to adapt to live in the marine environment. Seagrass has many functions, such as a nursery ground, a feeding ground and a spawning ground for fish and other biota that have high economic value. Various threats to the sustainability of the seagrass ecosystem in Indonesia continue to increase year after year. Commonly used seagrass transplant methods include the plug, sprig, tie sack and frame method. Kawaroe et al., (2008) stated that the method that produced the highest seagrass yield was the plug method. Likewise, Lanuru et al., 2013 found that the plug method resulted in a better survival rate compared to the staple and frame method. The success of a transplant method is also largely determined by the characteristics of the substrate at the transplant site. According to Lanuru (2011), the sediment characteristics consisting of fine, muddy sand are better than coarse sand and less muddy as a substrate for Enhalus acoroides seagrass transplantation.

Abstract

Increased activity in the industrial sector can increase the production of solid, liquid and gas waste. Industrial waste that is indicated by heavy metals can reduce environmental quality. Heavy metal pollution can occur in soil and waters which will disturb the ecosystem in it. Heavy metals not only have a negative impact on the environment but also on the health of the human body. There have been many chemical and physical techniques for dealing with heavy metals, but they are still not effective because these techniques are considered to increase the level of pollution and require a large amount of money. Therefore, the remediation technique using hyperaccumulator plants is one of the solutions in efforts to resolve heavy metals polluted in a soil and waters. Vetiveria zizanioides, Sansevieria trifasciata, Eichhornia crassipes are hyperaccumulator plants of capable absorbing and accumulating heavy metals by phytoextraction, phytodegradation and rhizofiltration mechanism.

Abstract

Tukad Yeh Poh is categorized as a sub-river basin unit which plays an important role for the irrigation purposes and daily life support for the surrounding areas. The water quality along the river is analyzed using Pollution Index (PI) method to compare nine parameters with the standard value class II, including seven chemical parameters (DO, COD, BOD, Pb, PO4, NO2, NO3, oil and fat) and microbiological parameter (Coliform) throughout three sampling points to represent the upstream, downstream and middle point. The measurement is following the administration area of Badung Regency during the dry season that is represented by June 2019. There are five chemical parameters showing a larger concentration compared to the standard value. Moreover, the PI calculation suggested that the upstream and middle point should be categorized as lightly polluted, while the downstream region labelled as moderately polluted.

Abstract

Bali island as one of the best tourism destinations in the world is producing waste around 4.281 ton/day, including the temple waste. Every month, over 3 million Balinese Hindus carry out ceremonies. At the end of the day, each temple produces about 2000 L of temple waste, which is directly disposed to landfill without any treatment due to the insufficiency of waste processing facilities. The treatment of temple waste potentially such as water sanitation, waste accumulation, pollution, and human health. This study describes the characteristic of temple waste generated from home and the efforts of temple waste recycling initiatives. The temple waste is generally composed by 80% of organic material, such as flowers, leaves, fruit and food waste, coconut, bamboo, and in other side the plastic does exist. Some initiatives in recycling the temple waste were done in the previous research, such as aromatherapeutic incense from discarded flowers, generating vermicompost by mixing the discarded flowers with cow dung, and producing biofuel from marigold flowers. A recycling improvement is urgently needed by the existing temple waste in Bali. It is expected that Balinese Temple as the cultural icon of Bali would not be longer become the waste contributor to the landfill.

Abstract

Predictions for ten years of methane gas emissions in research are conducted on wastewater. To predict the emissions of methane gas ten years first calculated the level of methane gas emissions. Then made predictions to know the emissions of methane gas produced by domestic wastewater for the last ten years. This domestic wastewater from rusunawa. The calculation of methane gas emissions is carried out with reference to the method developed by IPCC 2006. Based on calculations, household wastewater generates methane gas emissions in 2007 of 5648.75 kgCH4 / year or 8610.91 m3 / year and continues to increase each year. The methane emission prediction result yields the equation y = 1538x2 + 5836x + 16610 to predict methane gas emissions over the next ten years. While the conversion of electrical energy in 2007 amounted to 770.90 kWh and increased every year along with the increase in methane gas emissions. The prediction result of electrical energy yields the equation y = 137,7x2 + 522x + 1487 to predict electric energy ten years ahead.

Abstract

The objectives of tourism development are to introduce, utilize, protect and improve the quality and attractiveness of tourism, maintain Balinese environmental protection norms, religious values, culture and natural life, prevent negative impacts caused by tourism activities, and improve the welfare of the community. The tourist attraction of the Candi Tebing Gunung Kawi is a sacred area located in the Banjar Penaka, Tampaksiring District, in Gianyar Regency. The results of preliminary observations on geological traces in both places show the unique formation, stratigraphy, and rock-forming minerals to be revealed either from the volcanic activity of Mount Batur and also influenced by tectonic activity that had taken place at that time. The results of this study indicate that the rock stratigraphy at the Candi Tebing Gunung Kawi tourist attraction belongs to the principle of lateral sustainability. The role of geotourism looks very significant in revealing the role of geology in tourism development, especially in the Pura Gunung Kawi. Local wisdom that is used is to prohibit tourists who are on their period from entering tourism sites, and conducting searches with the aim of cleaning the temple in a nocturnal manner which is carried out every piodalan, puja wali or caru manca kelud every 10 years.
