Abstract

The background of this study was our concern on the sustainability of the environment wich was an asset for tourism. For nature-based and nature-related tourisms, maintaining of nature attraction which was the main focus point for tourism was an important agenda. The destruction of the environment would reduce its attractiveness and as a result would change its reputation as a tourist destination. Nature-based and nature-related tourisms tended to have unique values, and recently more tourists had an interest in nature. Easy and good accessibility and the presence of potential markets contributed to the development of these types of tourist attractions which then uncontrolled developed into mass tourism. In other to maintain the environment, it was important to find out wether the strategic plan for tourism development had a concern to the sustainability of the environment. Some cases of nature-based tourism development had made environment to damage as tourists’ visit might cause decrease int the species diversity, erosion, pollution, contamination and decreased visual landscaping quality. Very often, the gradation had already reached decreasing phase of ’survivorship’ of nature, which would influenced onto the environment quality. As a result the visitors would feel uncomfortable to visit this destination anymore. This was because of there was no integrated management yet established, especially between economic and ecologic visions in taking decision on planning and on the strategy tourism development processes. In order to keep the sustainability of the environment, which minimizing the negative impacts, this article was written to find out planning and strategy on sustainable development of nature-based tourism. The method of writing this article was utilizing literature review and also some continuing research.

Abstract

AbstractEncroachment of protected forest known as ngawen in Jembrana is a violation against theforestry laws, potentially harming the forests and infringing the basic idea of feminism. Inthat respect, this paper is going to examine the strategies and implications of the activity inthe perspective of ecofeminism. In perspective of ecofeminism, it is obvious that ngawenactivity is carried out with a strategy reflecting the anthropocentrism and androcentrism.On the one hand, it implicates the increasingly severe destruction of protected forest; whileon the other hand, it implies a less equitable gender relation in the domestic socio-economicaspect of the pengawens’ household.

Abstract

The hospital is one fairly large waste generators that produce adverse effects on the environment. This is because the waste has the potential to cause environmental and public health problems. Most hospital waste is a hazardous medical waste that is infectious. Research carried out in public hospitals WZ John Kupang showed fairly good efficiency. The WWTP used activated sludge have an efficiency of over 60% for all parameters and relatively efficient. The highest level of efficiency was the parameter of TSS (83.60%) and the lowest was the BOD (62.03%). However, the treatment of wastewater was classified not as effective with an average percentage of 60%, meaning that waste management which carried out was used all available resources but does not meet the expected target, or in other words sewage treatment efficient but not effective.

Abstract

This study of evaluation on policy effecitivity on the destructive fishing in small islands and coastal zone. Many government policy have not been successfully implemented due the lack of suprevision and monitoring. The destruction of coral reef has impact on economic income in the coastal zone citizen. Indonesia has lost its tremendous oceanic resources as the cause of destrucitice fishing through chemincal bombing on the sea to catch fishes. Its not only disaster for the longevility of the many kind of fishes but also coral reef which can only be recovered for hundred years. It is no longer a government roles to maintain the sustainability of these lives, but society and stakeholders should be involved as a team to increase the quality of the coastal zone society by improving their knowledge and skill for their fishing.

Abstract

There were 65 species of trees have been identified in Baturning village, District of Abiansemal, Regency of Badung, Bali, which were spread out around the river bank, cemetery (around Dalem temple), around the settlement, non-irrigated farm (plantation or “tegalan”) and rice field. Thirty eight (38) % out of them were observed to be available around the settlement. Most of trees in Baturning (61 species or 94%) have been used by the local community. The rest were uncultivated. From the use, trees in Baturning most were used for human consumption (24%). On the village has not been found protected species, even though in the village were found 22 species of trees which considered to be rare in Bali, namely: Bayur, Bentenung, Beringin, Cempaka, Ee, Jaka, Jeruk Bali, Juwet, Kelor, Kendal, Klampuak, Lempeni, Lenggung, Mahoni, Mengkudu, Palem Raja, Poh-Pohan, Pule, Sandat, Sentul, Udu, and Wani.

Abstract

Research to investigate the effectively of four legume species as intermediate host of sandalwood was conducted. Research consist of five treatments; in four treatments, sandalwood was grown with C. siamea, A. leucophloea, A. farnesiana or A. villosa while in one experiment sandalwood was grown without host. Host treatment significanlty affected growth of sandawood. Based on sandalwood height, of four legumes used the best host for sandalwood was A. farnesiana. Host treatment also affected sandalwood biomass. Root, stem and leaf biomass of sandalwood grown with A. farnesiana were higher compare to grown with other host. Generally, based on sandalwood biomass, C. siamea did not affected growth of sandalwood while A. leuophloea and A. villosa tend to reduce growth of sandalwood. Number of leaf and leaf area were also different between treatments. The highest was in sandalwood grown with C. siamea and A. farnesiana while grown with other host were lower. Root length was marginally different between treatments. However, root of sandalwood grown with host was longer compare to sandalwood grown without host.

Abstract

Penelitian ini adalah pengembangan penelitian sebelumnya yang berjudul Interpretasi Seismik terhadap Fenomena Lumpur Sidoarjo. Penelitian tersebut mengestimasi: 1) Volume cadangan lumpur yang tersedia, 2) Potensial energi yang membangkitkan power untuk menyemburkan, 3) Potensi semburan baru di lokasi sekitar semburan utama. Pengembangan penelitian pada paper ini adalah membuat dugaan atau hepotesa awal bahwa mud volcano adalah fenomena alam biasa dan akan bersifat permanent. Dugaan ini utamanya berdasarkan analisa geologi struktur. Struktur lapisan batuan sumber lumpur adalah layered dan memiliki kemiringan yang cukup terjal, sehingga beda ketinggiannya menyebabkan adanya potensial energi gravitasi untuk menyemburkan lumpur. Apabila diasumsikan bahwa lapisan sumber lumpur terus terisi oleh air tanah akibat ilfiltrasi pada setiap musim hujan, maka semburan tidak akan berhenti. Penelitian yang sedang berjalan memberikan konfirmasi bahwa data debit semburan selama 18 bulan memberikan kecenderungan demikian, yakni pada musim hujan membesar dan menurun pada musim kemarau. Area rentan sesar (collapsed area) di atas lapisan batuan sumber lumpur juga memberikan kontribusi tentang kerentanan munculnya semburan baru. Kerangka analisa yang digunakan sebagai referensi dalam penelitian ini adalah komparasi terhadap kejadian mud volcano yang wajarnya ada di dunia.

Abstract

Telah dilakukan penelitian tentang pengaruh panjang gelombang cahaya terhadap lajupertumbuhan dan karakteristik klorofil-a pada tanaman tomat. Panjang gelombang cahayayang digunakan pada penelitian ini adalah 450 nm, 470 nm, 550 nm, 650 nm dan 680 nm denganintensitas masing-masing 1000 lux. Penelitian dilakukan mulai saat pembibitan dari hari ke-0sampai dengan hari ke-18 dan fase pertumbuhan dari hari ke-19 sampai dengan hari ke-53. Saatpembibitan, penyinaran dengan panjang gelombang 680 nm mempunyai laju pertumbuhanpaling besar dibandingkan dengan panjang gelombang lainnya bahkan lebih besardibandingkan dengan pembibitan dibawah sinar matahari (dialam bebas) khususnya padahari ke-1 sampai dengan hari ke-8. Laju rata-rata pertumbuhan dengan penyinaran panjanggelombang ini sekitar 1,11 cm/hari. Sedangkan pada fase pertumbuhan penyinaran denganpanjang gelombang 680 nm tidak memberikan efek yang berarti, sebaliknya laju pertumbuhanpaling besar pada fase ini terjadi pada penyinaran dengan panjang gelombang 650 nm.Kenyataan ini juga diperkuat dengan pengambilan data klorofil-a. Berdasarkan data yangdiperoleh, laju pertumbuhan dan kadar klorofil-a dari penyinaran dengan panjang gelombang650 nm masing-masing adalah 0,07 cm/hari dan 7,784 mg/L. Berdasarkan data-data pengamatanmenunjukkan bahwa pertumbuhan tanaman tomat membutuhkan panjang gelombang berlainanyang merupakan fungsi waktu.
