Abstract

Belitung is an island on the south eastern coast of Sumatra, Indonesia. Geologically, Belitung is an continental island and during Pleistocene was united with Sumatra and Borneo to form a subcontinent named Sundaland indicated by the existence of an archaic Pleistocene river located in Tebat Rasau in the East Belitung Regency with the presence of Asiatic arowana (Scleropages formosus) and non-poisonous freshwater pufferfish from the genus Pao, which is identified here as resembling Pao hilgendorfii. The existence of these biota strengthening the concept of Sundaland and has put Belitung tributaries closer to mainland Borneo’s river system rather than that of Sumatra’s. Fascinating discoveries found in this current study are the fact that the people of Tebat Rasau acknowledge based on the presence of the Asiatic arowana and non-poisonous pufferfish about the union of Belitung with the mainland Borneo and Sumatra in the past long before the concept of Sundaland itself was formulated and published. This knowledge has put the people of Tebat Rasau more aware on the conservation of the area and fully supports the appointment of the Tebat Rasau vicinity as a National Geopark. The local products have also produced from the vicinity including the well-known herbal tea from the leaves of Pelawan tree (Tristaniopsis merguensis; Myrtaceae) known as “Pelawan Tea”.

Abstract

Realised the impacts of ecotourism to the local community, the study of ethnobotany mangrove was conducted to elaborate perception of local coastal communities related to mangrove habitat around them. Descriptive research method was applied. Interview technique was employed using systematic and structured instrument and depth interviewed was followed to the selected respondents. The instrument of questionare was validated before field survey took place. However, due to Covid 19 pandemic situation, the questionare then was distributed via online. From 100 expected respondents, only 55 questionerres were returned. The result showed that all local people (100%) was familiar with mangrove and 65% (36 respondent) had adequate knowledge about mangrove and its benefits such as for medicine (14%), for food (33%), for house hold (15%), craft (15%) and other purposes (23%). In regard to the connection of mangroves with industries, the data showed that 23% respondents answered positive and 77% was divided between no and have no idea. The research also identified consent of local community to ecotorurims program and found 94% approved and support the program, even though only four respondents (6%) has joint in tourism training that conducted by government. For the future of mangrove in Muara Gembong as ecotourism, the expectancy of community was relatively various, included financial assistance (35%), ecotourism trainings (7%), education (10%), mangrove cultivation and management (21%), and others was 17%.

Abstract

Kumbang kotoran Scarabaeidae merupakan bioindikator kwalitas lingkungan melalui perannya sebagai pengurai (decomposer) yang ditunjukan dengan variasi struktur komunitasnya. Studi ini dilakukan untuk mengetahui struktur komunitas vertikal kumbang Scarabaeidae pada ketinggian 900, 1400 dan 2000 mdpl di lingkungan Taman Nasional Gunung Halimun Salak (THNGHS) Jawa Barat. Metode penelitian yang dilakukan adalah Pit Fall Dung Trap dalam suatu belt transect  pada lajur pendakian (tracking). Pada setiap ketinggian disiapkan sebanyak 5 (tiga) perangkap mengikuti jalur transect dengan jarak antar perangkap sejauh 10 meter. Pada penelitian itu juga dilakukan pengukuran in situ parameter abiotik utama  dianggap mendukung kehidupan hewan tersebut, yakni susbtrat tanah dan pH tanah. Hasil penelitian ini menunjukkan terjadi perbedaan struktur komunitas pada setiap ketinggian yang ditunjukkan dengan indeks diversitas (H’) yakni pada ketinggian 900 mdpl adalah H’= 0.80 (rendah), 1400 mdpl memiliki H’= 1,29 (sedang) dan H’=0,84 (rendah) dietmukan pada ketinggian 2000 mdpl. Struktur komunitas kumbang di THNGS dibangun oleh 2 (dua) genus kumbang yakni Onthophagus dan Copris, 4 spesies yakni O. taurus, O. semicupreus, O. babirussoides dan Copris punctulatus. Species yang mendominasi adalah Onthophagus taurus dengan jumlah individu 339 ekor atau 60% dari keseluruhan jumlah individu kumbang yang ditangkap pada penelitian ini. Sedangkan Onthopagus babirussoides adalah kategori species jarang (rare species) dengan jumlah koleksi sebanyak 47 individu atau sekitar 8% dari keseluruhan. Hasil ini memperlihatkan telah terjadi penurunun kualitas lingkungan di TNGHS yang diperlihatkan melalui strukture komunitas Scarabidae dengan keragaman yang relatif rendah.

Abstract

 The study of macrozoobenthic in seaweed culture in Muara Gembong Estuary, Bekasi District, West Java Province, was conducted in May to July 2018. The study was aimed at understanding the roles of macrozoobenthic organisms as ecosystem engineering in seaweed habitat by identifying macrozoobenthic community structures using various biological indices. Sampling sites were conducted at three selected intertidal ponds used for seaweed culture at different distances and perpendicular to the coastline. Samples of macrozoobenthic organisms were collected using an Ekman grab during low tide periods. The study results showed that the macrozoobenthic community from the three ponds were consisted of 9 major benthic families and 14 genera with a total of 139 individuals. The results also showed that gastropod of the genus Cerithiidae was the dominant taxa found in every pond which contributed to 42.45% of the total macrozoobenthic found in the three ponds and became the main contributing taxa to the macrozoobenthic community structure. In addition, genus Platynereis of the Polychaeta Class was found to be another important taxon which contributed to 14.39% of the total macrozoobenthic found in the three ponds. The genus Platynereis were mostly found in the second pond with muddy coarse sandy sediment substrate containing more silt compared to the other two ponds. The rare taxon was the genus Lithophaga from family Mytilidae represented by 1 individual. Our study concluded that the macrozoobenthic community structure in the three ponds was categorized as poorly diverse indicating that the pond system was unstable. The Shannon-Wiener Diversity Index (H’) was only 0.87 on average with the highest diversity index (H’=1.47) was found in the third pond located at the farthest area of the coastline. Meanwhile, the average of Evenness Index was 0.34 indicating that the distribution of the taxa was uneven with a tendency of being dominated by certain taxa.

Abstract

ARTICLE HIGLIGHTS- The study in Ujung Genteng coast presents clear evidence of moderate macroalgae diversities and community structure linked to environmental parameters and substrate type- The biological indices scores illustrated a spatial distribution pattern of macroalgae assemblages- Understanding these ecological dynamics of macroalgae is crucial for both conservation and sustainable seaweed cultivation.ABSTRACTThe study of benthic macroalgae in Ujung Genteng aimed to describe the spatial distribution pattern of benthic macroalgae based on various parameters that support their growth and influence the health status of the marine ecosystem. The study was conducted from May to December 2023. The observation sites were selected using a purposive sampling method across three coastal areas, chosen based on the physical landscape structure and distinct substrate types. The line transect quadrat method was used for data collection. The study identified 41 species of benthic macroalgae from 28 genera and 19 families. The bubble green algae Boergesenia forbesii emerged as the dominant species, accounting for 16.8% of the assemblages, although this difference was not statistically significant. The distribution pattern of macroalgae showed noticeable spatial variation, with the East Zone, located in the eastern part of the coastal area, considered the most favourable habitat, harbouring 32 species with 312 individuals. The health status of the marine ecosystem in Ujung Genteng was relatively good, indicated by moderate Diversity Index (H’) values around 2.52 to 2.70, high Evenness Index (E) values (0.73 to 0.82), and low Dominance Index (D) values (0.09 to 0.11). The measured abiotic factors also fell within ranges that support the growth of benthic macroalgae. Keywords: benthic macroalgae, spatial, distribution patterns, Ujung Genteng
