Abstract

Damage to coral reef ecosystems in the Bay of Kupang reaching 30.6%. Activities to restore coral reefs are also conducted through coral transplantation programs. Although this activity was relatively successful, but the power of coral reefs to recover relatively longer, while coral mining and destructive fishing in the areas within the region is still on going. The purpose of this research is (1) to investigate the effectiveness and efficiency of management 1WAL Kupang Bay. (2) To investigate condition of coral reefs live in Kupang Bay after the management and (3) to investigate condition of socioeconomic the communities around Kupang Bay after the management. The method of research used observation and direct observation in the field, with socioeconomic data retrieval techniques using quesioner and coral reef data using Line Intercept 'Jransect (LI11 method and discovery of documents which contain about the development of coral cover. The results showed that the communities around Kupang Bay 1WA L not know and was not involved in the preparation of management plan 1WA L Kupang Bay. Data on coral reefs show that damage continues to occur with a marked decline in coral cover prosesntase. Following up on these circumstances will require collaborative management mechanism that involves the community as one of the stakeholders in the area of the bay 1WAL Kupang.

Abstract

Since January 1992 MIC has initiate Tahura Ngurah Rai are as a ecotourism area, offering programs such as :Mangrove Education Tour & Tracking, Bird Watching; Finishing; Mangrove Tree Plantation or Adoption, Canoeing, andBoating programs. However, its growth has not me the management’s targets in term of the number of visitors, improvedfacilities available, and the surrounding Tahura are – especially its cleanliness-these are far from expectation standard.The evaluation of eco-tourism area of Tahura is aimed at understanding the profile of the eco-tourism area and tounderstand to what extent the ecotourism has met criteria/principles issued in the national workshop. This ecotourism willoffer recommendations designed in relation to programs that has not been working so far after identifying obstacles oftheir implementation.The method used in the evaluation of this eco-tourism area I descriptive analysis by analyzing interview data,observations, and literature studies. These descriptive data then are measured against criteria and principles of nationaleco-tourism.Since March 12, 2007 Mangrove forest area is under the management of BPHM-wil-I continuing JICA ICprogram. Facilities available in the area are as follows; Wood Trails, 5 Huts along the trail, Floating Decks, 2 ViewingTowers; MIC/BPHM Office Building, Touch Pools, Seeding area, and a Monitor Pool. These facilities right now are stillin good condition and can be used to implement the eco-tourism programs.From the 6 programs offered, the Mangrove Education Tour & Tracking Program gets the most interests fromvisitors than the other 5 programs. From 9 criteria used to evaluate the programs, the outcome is as follows: 1) Beingsensitive to and respecting socio-cultural values and religious tradition of local community (88% met); 2) Showingconcern, commitment, and responsibility to natural conservation and cultural heritage (95,24% met); 3) Provideinterpretation that facilities visitors to enjoy nature and increase their awareness and concern for nature (85,71% met); 4)Educational in which there is a mutual learning between visitors and community (100% met); 5) Its development be basedon local community through agreement (20% met); 6) Empower and optimize participant and at the same time bring forthon going contribution to the local community (0% met), 7) To go by existing rules and law (100% met); 8) Consistentlysatisfy the visitors (50% met), 9) Being marketed and promoted openly and accurately to meet expectation – that is amarketing responsibility (100% met). Generally the result from comparison between ecotourism program withprincipal/criteria are as follows : from nine principles that already explained only the fifth and sixth principal whose itsdevelopment less than 50%, based on those condition above it can be conclude that mangrove ecotourism developmentalready fulfill the principal/criteria of national ecotourism. Important points of recommendations to the management areas follows; community participation; retributions, waste management; improvement of programs that are not working;and eco-tourism management under a solid institution.

Abstract

Subak Jatiluwih in 2012 has been named as one of the World Heritage nomination from UNESCO. The level of tourist visits to Subak Jatiluwih continues to increase each year. The rate of environmental damage due the development of tourism is also expected to increase, and therefore need to be efforts to minimize environmental damage from tourism development. This study aims to identify the potential of ecotourism in Subak Jatiluwih, knowing how to manage the environment at the moment and assess environmental management strategies ecotourism, so that tourism development is carried out to provide benefits not only to the social and economic fields surrounding communities but also to the preservation of the environment in Subak Jatiluwih. The approach used in this study is a qualitative approach. The method of collecting data in this study using the observation, interviews and questionnaires. The data obtained were analyzed by descriptive qualitative analysis equipped with IFAS (Internal Factor Analysis Summary), EFAS (Exsternal Factor Analysis Summary), SWOT (Strength Weakness Opportunities Threats) analysis and QSPM (Quantitative Strategies Planning Matrixs) analysis to determine strategic priorities has been produced. Based on the observation the environmental potential of ecotourism in Subak Jatiluwih is abiotic potential consisting of rice field panorama, Besi Kalung Temple panorama, wellsprings, waterfall, hot springs, river. Biotic potential include brown rice, Kokokan bird. Social and cultural potentials include the existence of subak organization, technology used in water distribution system, myth, potential of 13 traditional ceremonies conducted in Subak Jatiluwih. The results of SWOT analysis, there are four strategies that is Strength Opportunities Strategy (SO), Strength Threats Strategy (ST), Weaknesses Opportunities Strategy (WO) and Weaknesses Threats Strategy (WT). Each of these strategies are translated into programs in environmental management of ecotourism in Subak Jatiluwih. QSPM analysis results a functional strategy with highest scale priority to be implemented is the development of tour packages based on agriculture, culture and nature. Ecotourism environmental management in Subak Jatiluwih requires completeness of supporting facilities and infrastructures such as improved roads, irrigation channels, parking and toliet. In addition to support of the empowerment local communities should reduce the use of migrants labor and involve local communities especially members of Subak as a tour guide, forming subak cooperatives and perform packaging of agriculturebased tourism, culture and nature, by limiting the number of tourists visit if its felt beyond the carrying capacity.

Abstract

Coral reef and its life within is a high value natural resources. Management of KKLD GiliSulat-GiliLawas has been going for 8 years, however the management was still not maximal, in particular on preservation of coral reef ecosystem in the conservation area, and community commitment in managing and conserving fish resources and other biota. Therefore, to improve management planning, study need to be done with the aim to find out destruction level of coral reef at KKLD GiliSulat – GiliLawang, based on coverage percentage, fishermen, private sector and government perception. Also to identify policy related with coral reef management in this area, then to formulate its management strategies. Results of the survey shows that in general, average condition of the coral reef in this area is fair (lifeform= 49,26%). Recommended management strategies in KKLD GiliSulat-GiliLawang include SO strategies (Strength - Opportunity) which are coral reef management should be based on ecotourism, increasing community involvement in managing the coral reed and improve institutional strength of KPPL, and maximizing function and task of UPTD KKLD. WO strategies (Weakness - Opportunity) are increasing monitoring, give training on coral reef conservation, improving partnership in management, and increasing quality and quantity of KKLD human resources. ST strategies are (Strength – Threats) socialization of regulation, increasing effective coordination among stake holder, accurate analysis of environmental impact and improve research and sustainable diversification on fishing businesses.

Abstract

One of the most severe environmental problems is heavy metal pollution such as Cr(VI) in aquatic ecosystems. Cr(VI) is toxic and carcinogenic heavy metals pollutants that persistent and easily accumulated through the food web. Accumulation of Cr(VI) concentration in the aquatic ecosystem gradually increases with the increases of industrial activity. Therefore, Cr(VI) concentration in aquatic ecosystems should be monitored continuously, and thus, suitable and accuracy monitoring technologies are necessary. This study analyzed the utilization of biofilm as a biomonitoring agent of Cr(VI) in the Badek River, Malang City. The concentration of Cr(VI) inside the biofilm and the surrounding water of biofilm were investigated. The results revealed that the concentrations of Cr(VI) inside the biofilms were hundred times higher than the surrounding water. The biofilm may accumulate Cr(VI) from the surrounding water resulting in the Cr(VI)-rich microenvironment inside the biofilm. The adsorbed Cr(VI) is retained mostly in the interstitial water of the biofilm matrices. The findings in this study suggested that the biofilm can be used as a potential biological agent to monitor of Cr(VI) pollutant in the river ecosystems.

Abstract

Natural conservation management is a very important task that not only aims to save the environment but alsosupport the people that live in it. All variables of life become part of the management goal which often blurs the phasesof management processes towards an effective one. This study aims to measure the effectiveness of conservationmanagement of West Bali National Park (TNBB) based on measured indicators.The methods of measuring effectiveness is based on several indicators (biophysical, socio-economics andgovernance) using the LIT (Line Intercept Transec) method to monitor coral reefs on 8 diving sites in TNBB. Thesocio-economics and governance indicator utilize questionnaire method and discussions with a sample of localcommunity selected randomly from 4 villages around the TNBB zone.The biophysical indicator demonstrate that the amount of coral reef cover in TNBB is 37,1% which falls underthe MEDIUM category. Meanwhile, the socio-economic indicator illustrates that the community relies very little onmarine resources and have an adequate understanding of conservation efforts and sustainable use of naturalresources. Governance indicator shows that stakeholders involvement is proceeding well with a good level ofsatisfaction regarding collaborative management process.Collaborative management of TNBB waters is quite effective in conserving coral reef ecosystem, which is builtfrom awareness, ownership and stakeholder commitment through a cooperation of various organizations called ForumKomunikasi Masyarakat Peduli Pesisir (FKMPP).

Abstract

Development in ??Batur UNESCO Global Geopark which has an area of ??19,422.39 ha has increased significantly in recent years. The existence of limited land and to know the suitability of land use, it is necessary to evaluate of land use with regional spatial plan (RTRW). Landsat 8 satellite remote sensing data on 27 September 2017 is used to create land use maps. Land use maps obtained through the process of image classification using supervised classification method and verified by ground check. From this technique result 11 classes of land use. Furthermore, to evaluate of land use suitability was conducted by comparing land use with regional spatial plan (RTRW). In this process, there is an overlay between the land use maps with regional spatial plan (RTRW) map using geographic information system (GIS). The results of evaluation land use in Batur UNESCO Global Geopark with regional spatial plan (RTRW) overall has suitable area 10,863.14 ha (55.93%), not suitable area 8,275.58 ha (42.61%) and not detected/cloud interference 283.67 ha (1.46%).

Abstract

Potential fishery in territorial water of South Java - Sumbawa Sea has not been exploited maximally. Tuna is one of fisherypotency in the territorial water of South Java - Sumbawa. Tuna is the important economic value because it represent one ofexporting commodity enthused by overseas consumer.Research was conducted in the Southern Java – Sumbawa, Indian Ocean 90 S - 160 S; 1060 E - 1210 E, using fish catch data2003 – 2006. Research location is in the inclusive Region of Fishery Management IX (DKP and PKSPL, 2003). Data weretaken from a daily fish catch of PT. Perikanan Samudra Besar (PSB) Benoa Bali 2003 - 2006.Sea level anomaly (SLA) data were estimated from Altimetry satellite (Jason 1), wind speed data was from Scatterometersatellite and sea surface temperature (SST) data was from Microwave satellite.Based on the result of this research, sea level anomaly of southern coast of Java-Sumbawa was fluctuated according tomonsoon. The highest bigeye tuna fish catched was 40 tuna in June 2003 and the lowest bigeye tuna fish was 2 tuna inNovember 2005. Maximum SLA observe during southeast monsoon was 21.77 cm in august 2005, while minimum SLAobserved during southeast monsoon was -18.15 cm in October 2003. Sea surface temperature of southern coast of Java-Sumbawa also fluctuated according to monsoon. Maximum SST observed during northwest monsoon was 30.450 C in March2006, while minimum SST observed during southeast monsoon was 25.050 C in August 2006. The highest wind speed was10.20 m/sec in June 2004 and the lowest was 2.00 m/sec in October 2004. Wind direction was reversely changed according tomonsoon. Northwest wind monsoon flew eastward and southeast wind monsoon flew westward.Fish production in PT PSB had been done over 4 years since 2003, in northwest and southwest monsoon in constant areaand correlation of linier regression among estimate of fish catching using SLA, SST and wind speed had no correlation. Withfish production during southwest monsoon PT PSB set in SLA negative in different temperature of 30 C, wind speed of 2.00m/sec and with abundant of fish catched. Meanwhile in northeast monsoon that was in positive SLA the fish catching was inlow number.

Abstract

ago. This traditional organization is socio-religious in nature based on the high spirit of cooperativework. It is very effective in support of the development of agriculture in Bali and it serves as an inheritanceof highly noble value so that it deserves to be conserved. Development in globalization and modernizationera indeed starts to push the subak culture either interms of pelemahan, pawongan, and parhyangan. SubakBulan pesedahan of Yeh Sungi Mengwi District Badung Regency whose irrigation water quite depends uponwater source has been disturbed since some of the beji water source of Baha village has been taken by otheruser.This study aims to know the impact of the taking of water from beji water source of Baha villageagainst the availability of irrigation water for Subak Bulan, the perception of subak members for the takingof the water and what is the relationship of the change of use of rice field in the Subak Bulan area with thetaking of water in the water source. The method employed is descriptive and corational method. Datacollecting by means of field observation in every water source and intake, interview with respondents usingquestionnaire for 48 respondents out of 303 Subak Bulan members.The findings show that the availability of irrigation water for Subak Bulan has its source from watersource and some of the water coming from the technical irrigation of Yeh Sungi quite fluctuates caused bythe change of season and the water debit from the upstream irrigation water because the location of SubakBulan is in the most downstream part of the irrigation network of Yeh Sungi. The availability of irrigationwater in each block (munduk) is not optimal. The perception of Subak Bulan to the taking of beji sourcewater of Baha village is that most of the villagers know this and they feel this is disadvantageous to them.There has been a change of land use in the area of Subak Baha as a result of water availability, economic,and social factor from 2000 to 2005 covering the area of 5.25 ha. The relationship between the change ofland use in Subak Baha and the taking of water in beji water source of Baha village shows negativecorrelation which is very significant at- 0.8875 caused by a number of factors among others being the time period for taking the water, opening ofnew roads, lack of water, land opening for settlement.It can be concluded that there is a lack in the availability of irrigation water of Subak Bahainequitably and it fluctuates as a result of the change of season. There is a need for replanning of blocks ofrice fields that need to be irrigated so that the source water of Subak Bulan and the interest of Baha villageare not dissatisfied therefore the source water should be well and fairly managed and preserved. The role ofthe government is also hoped in such a way that it serves as a mediator and makes regulations related to themanagement of the water resources available within the area of Subak Bulan.
