Abstract

The existence of indigenous forest is very important as it constitutes a source of the see-producing area and can be also user as a research site. Unfortunately, the information about types of vegetation in the area of Bukit Tunggal forests is relatively scarce. This research aims to describe the vegetation diversity in Bukit Tunggal forests and to identify types of vegetation which are the most dominant in the area. This research was conducted for 4 week in the indigenous forest of Bukit Tunggal at Batu Nanta Village, Belimbing sub-district, Melawi. A survey method was employed in this research through a vegetation analysis with a line of terrace. The research was carried out by creating 3 lanes with the length and distance of each lanes varied depending on the condition of the field. Results of the discussion showed that there were 77 types of vegetation which could be grouped into 37 families ranging from a seedling stage (including lower plants, shrubs, bushes, and lianas), stapling, poles, to trunks. The vegetation diversity in Bukit Tunggal forests indicated that the area had a high diversity with a good conservation value. In addition, the forests has various germplasms. Results of a quantitative analysis of crucial value index (INP) at every growth level in general was dominated by meranti (Shorea spp.) of Dipterocarpaceae family. There needs, therefore, efforts to preserve the existence of this area in addition to the current conservation which has been planned and executed well, for example by enriching types and rehabilitation.Keywords: Indigenous forests of Bukit Tunggal, diversity, crucial value index, and type domination.

Abstract

Gastropods are a single shell mollusk phylum. Gastropods have a really significant function, particularly in the mangrove ecosystem. Mangrove forests are a very supportive habitat for gastropods. Gastropods have a very important role in the processof decomposing litter and maintaining nutrient dynamics in mangrove forests. This study aims to obtain and analyze data on the diversity of gastropods in the mangrove forest ecosystem in Sentebang Village, Jawai District, Sambas Regency. The research wasconducted in June 2020 using survey methods and data collection techniques using purposive sampling. Based on the results of the research that has been done, it was found that there were 11 types of gastropods from 5 families. The types of gastropods found were Nerita violacea, Cerithidea obtusa, Cerithidea cingulata, Littoraria melanostoma, Littoraria scabra, Littoraria angulifera, Pythia plicata, Ellobium aurisjudae, Cassidula nucleus, Cassidula aurisfelis, Spherassiminea miniata. The gastropod diversity index in line 1 = 1.2246, line 2 = 0.8689, and line 3 = 0.9554. Track 1 is in the medium category, for lines 2 and 3 it is in the low category. The overall diversity index is 1.6239 which is in the medium category. The similarity index for the types of gastropod lines 1 and 2 = 40%, lines 2 and 3 = 25%, lines 1 and 3 = 20% which are included in the low category. Abundance index of gastropod type line 1 = 21.8, line 2 = 5.3, line 3 = 5.1. The evenness index of the gastropods line 1 = 0.6834, line 2 = 0.6268, line 3 = 0.6892. The overall evenness index is 0.6772 which is categorized as an unstable community. The gastropod dominance index line 1 = 0.3684, line 2 = 0.5186, line 3 = 0.4748, line 1 and 3 are in the low category, while line 2 is in the high category. The overall dominance index is 0.2574 which is in the low category, meaning that no type dominates. Based on the data that has been obtained, it can be concluded that the diversity of gastropods in the mangrove forest ecosystem in Sentebang Village, Jawai District, Sambas Regency is classified as moderate.Keywords: Gastropods, mangrove forest, species diversity

Abstract

This study aims to determine the rate of decomposition and the nutrient content of carbon (C-org), nitrogen (N) and phosphorus (P) of mangrove leaf litter released during the decomposition process. The method used is purposive sampling, where the determination of observation stations is based on the year of mangrove planting, namely 2007, 2010, 2013 and 2016. The analysis of litter decomposition rate uses the Boonruang equation, C-org uses the Walkley & Black method, N uses the Kjeldahl method and P uses the wet destruction method. The results showed that the most significant decomposition rate occurred in the 2016 planting year litter of 71.924%, followed by 2007, 2010 and 2013 planting years with a value of 58,582%, 55,360% and 47,048%, respectively. The highest nutrient content of C-org and P was found in mangroves in the 2010 planting year with values ​​of 50.82 and 0.14 ppm, and the highest N nutrient content was in the 2007 planting year with a value of 1.25%. In conclusion, the mangrove leaf litter during the research was not completely decomposed. The decomposition process in the 2010 planting year had the highest C-org and P-released nutrients. The highest N nutrient content was found in the 2007 planting year. Keywords: Decomposition Rate, Mangrove, Litter

Abstract

Macrobenthos is one of the organisms that play an essential role in the decomposition process of mangrove plant litter. Other organisms then use the result of the decomposition process in mangrove forests. Still, the existence of these organisms is susceptible to environmental changes, so it is often interpreted as one of the indicators of habitat quality. This research aims to determine the sustainability and diversity of macrobenthos as an indicator of habitat quality in mangrove forests. Data collection is carried out by the plot cluster method. Sample deflating points using purposive sampling. Cluster plots are placed on three observation stations with different conditions, namely natural mangrove forests (station 1), former pond areas (station 2), and areas adjacent to agricultural land (station 3). Each station has three plots measuring 10 x 10 meters to record tree level mangrove vegetation. Each plot has five subplots measuring 1 x 1 meter to take macrobenthos samples. The total number of plots is nine plots for mangrove vegetation and 45 subplots for macrobenthos. The results showed that macrobenthos ability ranged from 10 individuals / m2 to 15 individuals / m2, with the diversity index ranging from 1.49 to 1.73. This condition illustrates that mangrove habitat is included in the medium classification in other words, based on the state of the structure of the biota Bentos community in the mangrove forest in Siantan District, Mempawah regency is fairly a stable category.
