Abstract

Mangrove forests around Lake Meno have a great potential to be developed as a tourist area, especially birdwatching. The people in Gili Meno have a high dependence on mangrove forests, mainly for firewood, causing its damage continually increased. Development of tourism infrastructure is also contributed to the problem of land use. This is because of no clarity in land use plan. Degradation of mangrove forests is a threat in the effort to develop of birdwatching ecotourism in Gili Meno, as well as threaten environmental sustainability. This is an action research, through Participatory Rural Aprecial method, aims to: 1) make a strategic plan of management of birdwatching ecotourism, in Gili Meno, 2) improve the quality of human resources as a birdwatching guides, and 3) improve the quality of natural resources as bird habitat. The study resulted in strategic plan of management of birdwatching ecotourism, that involving relevant stakeholders. It is hope that no conflict of interest in the land utilization. A total of 3,000 mangrove seedlings have also been successfully grown. Birdwatch training has also been successful in increasing knowledge and skills of Meno Lestaris Clubs in conducting birdwatch in the field. A total of 25 species of birds have been well identified by this club.

Abstract

Gili Trawangan has a high diversity of coral reefs and is one of the Aquatic Parks in Eastern Indonesia. This diversity has begun to be threatened by the human activities and natural disaster due to climate change. So we needed to start doing some rehabilitation projects. The creation of Biorock is one of coral rehabilitation method which can increase growth rate of coral. This study was to determine the growth rate of colonies of Acropora formosa and Montipora digitata growing on Biorock substrate and away (up to 10 meters) from Biorock substrate.This study was conducted in Gili Trawangan from April to August 2011, and used a method of direct measurement on colony height. The result of t-test analysis showed a significant difference between the coral growth on the Biorock substrate and outside Biorock substrate. The height of A. formosa colonies transplanted on Biorock substrate (0.43 cm/week) is around four times faster than that outside of Biorock substrate (0.09 cm/week). The growth of a M.digitata colonies on Biorock was 0.3009 cm/week while outside Biorock at was 0.009 cm/week.

Abstract

Harmful Algal Bloom (HAB) incidences in Indonesian waters were increasingly occurred from time to time. Extensive and continous studies in this field are needed to be done in more areas in the country. This objective of this present survey were to determine the occurrence of potential toxic and harmful marine microalgae in Lombok, to reveal the diversity of marine microalgae found in the area, and to give some information on the occurrence of HAB phytoplankton in Lombok island. Plankton samples were taken from six stations in Lembar bay, Lombok on February, 2007. This survey found 23 marine microalgae species and two of those were potentially harmful and toxic, namely Dinophysis caudata and Gymnodinium catenatum. Four species, such as Ceratium spp, Dinophysis miles, Prorocentrum gracile, and P micans, were noted to be harmful though so far no report on adverse effect caused by these microalgae in the area. Diatom Chaetoceros spp were the most abundant phytoplankton in almost all of the sampling areas and followed by Ceratium furca and Protoperidinium sp.

Abstract

Dalam upaya konservasi burung koak kaok (Philemon buceroides) di Taman Wisata Alam (TWA) Kerandangan yang merupakan salah satu burung yang berstatus terancam punah, maka penelitian tentang populasi dan karakteristik habitat burung tersebut sangat diperlukan. Penelitian ini menggunakan metode wawancara dan observasi. Wawancara dilakukan kepada masyarakat di sekitar TWA Kerandangan, pengunjung serta instansi yang bergerak di bidang konservasi. Responden yang diwawancarai adalah dari berbagai kelompok umur, untuk menggali informasi tentang burung koak kaok dari masa lampau hingga kini, dengan jumlah responden sebanyak 30 orang. Setelah metode wawancara, peneliti melakukan observasi di lapangan dengan menjelajahi kawasan TWAerandangan pada beberapa lokasi pengamatan yaitu Camping ground (608,82 m2), Selter 2 (613,53 m2), Selter 4 (573,11 m2) dan belakang pos (542,94 m2), dengan penjelajahan antara pukul 06.00-10.00 dan 16.00-18.00. Kapadatan populasi saat ini hanya 0,18 individu/ha yang tergolong rendah. Di sebabkan karena karakteristik habitatnya didominasi oleh pohon yang tajuknya sangat rapat sehingga burung koak kaok sulit mencari makan ataupun beraktivitas.

Abstract

Coral reefs, mangroves and birds are becoming the major attraction of tourism in three islands - Gili Meno, Gili Air and Gili Trawangan (Gili Matra) - Lombok, Indonesia. Since the launching as a conservation area in 1993, tourism in Gili Matra has grown rapidly. On the other hand, the ecosystem continues to be degraded. Sooner or later, the ecosystem degradation will affect tourism and economic sustainability of the community in Gili Matra. The purposes of this study were to identify the stakeholders, and to map the ecosystem management problems in Gili Matra, to provide the basis for policy making in the future. The research method was depth interviews and focus group discussion (FGD). Identification of stakeholders was conducted using stakeholder analysis, while mapping of ecosystem management problems was carried out by participatory mapping. The stakeholders, who manage the ecosystem as tourism assets in Gili Matra, are: government, community and businessmen. The fishermen, tourists and businessmen are the primary stakeholders, meaning they have a high interest and the greatest influence on ecosystem management. Destructive behavior of stakeholders, especially the main stakeholders has led to the degradation of the ecosystem in Gili Matra, so it is important to nurture these stakeholders, to sustain tourism and economic viability of the community in Gili Matra.

Abstract

The existence of Ephemeroptera, Plecoptera, and Trichoptera (EPT) in a body of water can be used as indicators of the quality of the waters. The aim of this study were 1) to know the diversity of EPT insects in Jangkok River, Lombok, West Nusa Tenggara, 2) determine the water quality of Jangkok River based on family biotic index (FBI), and 3) to know the effect of physical, chemical, and biological of environment parameters on the presence of EPT insects. Sampling was conducted in Jangkok River, Lombok, West Nusa Tenggara, in the dry season of July 2016. EPT groups insects were taken using water nets and eckman grab in 22 sampling points that was randomly determined in systematic random sampling. Data of physical, chemical, and biology of waters were also taken in these sampling points. Water quality is determined by the score of FBI, and the multiple correlation analysis to determine the relationship between physical and chemical parameters with the presence of EPT. Biological parameter was analyzed descriptively. The influence of biological parameter was determined by descriptive analysis. The study found 902 individuals of EPT belonging to 12 family and 12 genera. In the upstream we found 788 individuals (12 family and 12 genus), in the middlestream found 114 individuals (10 family and 10 genus), while in the downstream the EPT was absent. From the seven physical and chemical parameters of waters tested, only water temperature has significant correlation with the presence of EPT. The differences of water temperature in these area were caused by the covering and heterogeneity of the vegetation in the river side in each area. FBI score for upstream was 3.6 which indicates that the quality of the waters are very good. In the middlestream, the FBI score was 4.6, and it was categorized as good. In the downstream, results of the FBI get infinite value that entered the category as very bad.

Abstract

The seagrass community are angiosperm plant communities that mostly grow in shallow marine waters. The community has an ecological role and function, both as a habitat for various types of biota and as a carbon sink. The purpose of this study was to determine the type and condition of the seagrass ecosystem in Kelapa Island based on the percentage of cover; and to determine the estimated carbon stocks of seagrasses contained. Seagrass community data collection was carried out in September-October 2020 in the waters of Kelapa Island, Bima Regency, West Nusa Tenggara Province. A quadratic transect was used for data collection of seagrass cover, and analysis of seagrass community cover using the PhotoQuad application, followed by determining the condition of the seagrass community ecosystem, and analysis of estimated carbon storage using the Loss On Ignition (LOI) method. The results showed that there were 4 types of seagrass found, consisting of: Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, and Halodule pinifolia. The percentage of seagrass cover is 52.31%, because it is less than 60%, the health status of seagrass beds is unhealthy based on the Decree of the Minister of the Environment Number 200 of 2004. Total carbon storage is 16.1 gr.Cm-2. Thalassia hemprichii as the highest carbon storage species was 8.27 gr.Cm-2.
