Abstract

Coral reefs ae onne of the ecosystems who have both ecological and economical function. I Gunung Malang community, coral reef have been used as main mateerial in lime powder production. The aim of this research to identified the species, distribution and capacity of coral reefs in lime powder production and than how the marketing system of the product. This research conducted from January to September 2018. The data was collected by measurement and identificatio of coral ad then interviewed the lime powder labours. The result of the research reported 29 species of coral from 17 genera and 8 families which was taken in 9 locations, six of it are live coral reef sites and the other are dae coral sites. Acropora abrolhosensis is dominant species with 605 Kg of coral mininng, followed by acropora sp with 535 kg and acropora palifera with 307 kg. The capacity of coral used inn are processig of lime powder production between 2000-3000 Kg, it will product 60-100 sacks of lime powder with 25 to 30 Kg in each sack. The lime powder in not sale directly to the consumers by the producer but it saleing to mainn collectors and then distriuted to the consumers or building stores.

Abstract

One group of invertebrates that live in the mangrove ecosystem is Mollusks of mainly Gastropods and Bivalves. They are associated with mangrove as life, shelter, spawning, and also as a place to get food to support the growth them. The purpose of this reaserch was to look at the effect of mangrove species and substrate type on the distribution Mollusks (Gastropods and Bivalves) in the mangrove ecosystem of Pelangan Village, district of Sekotong, west Lombok regency. This type of reaserch is descriptive explorative. Sampling was done by purposive sampling method with determine tree species, size, and substrate. Repeatation held six times each mangrove species. The results showed that there are 25 speciesd of mollusk in mangrove ecosystem, the most abundant species of gastropod in mangrove species is Clypeomorus moniliferus with a value of 6.9 ind / m2 contained in Osbornia octodonta. As for the distribution of each species of gastropods and bivalves are not affected by the mangrove species, but is influenced by environmental factors which in this case is a substrate.

Abstract

Lisong tuna (Auxis rochei) is one of high economic potential value of fish because of its abundance and often found in the fish market in Ampenan. Evaluating the impact of fishing to the growth pattern of length-weight of tuna is needed to ensure the sustainability of lisong tuna population. It is feared that the high intensity of tuna (A. rochei) fishing can cause growth disturbances and a decrease in local tuna populations. This study aimed to determine the relationship between the weight and length of lisong tuna (A. rochei) to their growth patterns in the fish market of Ampenan. Thirty individuals of lisong tuna were collected from two fish markets, Bintaro and Kebon Roek, in Ampenan. The equation of Linear Allometric Model is used to evaluate the length and weight relationship in growth patterns of lisong tuna. This study resulted in the positive allometric growth pattern of lisong tuna with slope value more than 3 (b=3.79). It indicated that the lisong tuna which were collected in Bintaro and Kebon Roek markets have a weight growth rate faster than their length growth rate. It means that the lisong tuna sold in Ampenan markets is quite fleshy and has a good growth rate.

Abstract

Timbanuh Hiking Track is one of the hiking tracks in Gunung Rinjani National Park. This track has four types of potential habitats for birds. This research aims to map bird diversity and their distribution along the Timbanuh Hiking Track. Data collection uses the point count method. Observations were carried out eight times, with a repetition period of two weeks. Bird diversity was analyzed using the Shannon Wiener Diversity Index. Scatterplots are used to map the distribution of birds along hiking track. The results show that on the Timbanuh Hiking Track there are 46 species of birds belonging to 29 families, with a high species diversity index of 3.52. The distribution of bird species is closely related to the four types of habitats on the track. There are four species of birds that are protected based on Minister of Environment and Forestry Regulation Number P.106 of 2018, as well as two species with Near Threatened status according to IUCN. The high diversity of birds, the existence of protected bird species, and the threatened status of birds mean that conservation efforts need to be increased by developing bird habitats along hiking track.

Abstract

One of the most abundant kinds of organism that lived in coral reef ecosystem are fish. Fish rely on coral reefs for shelter, food, and breeding grounds. Lombok is one of the islands that have many hotspots of coral reef ecosystem, one of which is at Pandanan Beach. The precense of fish benefits in both tourism and local economy, however the data about reef fish that lived in Pandanan waters are less known. This research aimed to assess the community structure of fish species in coral reef ecosystem at Pandanan Beach. The method that was used for sampling were UVC (Underwater Visual Census) with BIT (Belt Intercept Transect) technique at three different stations. The results showed 554 individuals which consist of 34 species from 12 families had been identified. The community structure of fish in the three stations showed the moderate level of diversity, stable evenness index with low dominance, and density value of 0,73. Environmental parameters measurement indicate Pandanan waters are suitable for fish growth and survival.
