Abstract

Kerapu cantang (Epinephelus fuscoguttatus x Epinephelus lanceolatus) memiliki nilai strategis dalam marikultur di Indonesia dan menjadi salah satu komoditas unggulan perikanan di Lampung. Namun keberadaan ektoparasit berpotensi menurunkan produksi kerapu Cantang. Penelitian dilakukan untuk mengevaluasi prevalensi, intensitas, dan identifikasi ektoparasit pada kerapu Cantang di perairan Ringgung dan Durian Kabupaten Pesawaran. Metode penelitian dengan pengambilan sampel secara acak di dua lokasi karamba jaring apung. Pengambilan sampel sebanyak tiga kali dengan jumlah ikan sebanyak 30 ekor pada setiap lokasi. Pengamatan ektoparasit dilakukan di Laboratorium Kesehatan Lingkungan Balai Besar Perikanan Budidaya Laut Lampung. Hasil penelitian menunjukan ada 3 jenis ektoparasit yang menginfeksi kerapu cantang di Perairan Ringgung dan Durian yaitu Pseudorhabdosynochus sp., Neobenedenia sp. dan Brooklynella sp.. Ektoparasit Pseudorhabdosynochus sp. memiliki nilai prevalensi 100% pada lokasi satu, dan ektoparasit Brooklynella sp memiliki nilai intensitas 873 ind/ekor pada lokasi dua. Indeks keanekaragaman (H’) pada lokasi satu 0,18 dan lokasi dua 0,10. Indeks keseragaman (e) pada lokasi satu 0,27 dan lokasi dua 0,09. Indeks dominansi (c) pada lokasi satu 0,91 dan lokasi dua 0,96. Berdasarkan hasil tersebut nilai prevalensi tertinggi yaitu pada Pseudorhabdosynocus sp. dan nilai intensitas tertinggi pada Brooklynella sp.. Hasil juga menunjukkan adanya co-infeksi sebesar 30% pada sampel kerapu cantang berasal dari perairan Ringgung. Organ insang dominan terinfeksi oleh Pseudorhabdosynocus sp., sedangkan lendir didominanasi terinfeksi oleh Neobenedenia sp. dan Brooklynella sp.. Dibutuhkan pendekatan lain untuk mengontrol kelimpahan ektoparasit pada budidaya kerapu cantang di Teluk Lampung disamping menggunakan perendaman dengan air tawar yang selama ini dilakukan pembudidaya.

Abstract

Plastic waste will be degraded into microplastic which has a size of ≤ 5 mm. These microplastic particles change in size and color due to various natural processes that occur in the environment. The purpose of this study was to determine the shape, color and size characteristics of microplastics found around Pasaran Island. Sampling was carried out by taking microplastic samples in water and green mussels around Pasaran Island. Based on the research results, microplastic fragments, films, fibers, granules and foam were found. Microplastic colors consist of black, blue, green, yellow, red, clear, and white. Microplastic fragments, films and fibers were found in the <50µm to 1000 - 5000 µm size group. Granular microplastic types were found in the <50 µm to 100 - 500 µm size group and foam types were found in the <50 µm to 500 - 1000 µm size group.

Abstract

Halophila spinulosa (R. Br.) Aschers is a type of seagrass found in Indonesia with limited distribution. One of the areas where Halophila spinulosa is found in the Bangka Belitung Islands. Although found in the Bangka Belitung Islands, information on this type of seagrass is very limited. The objectives of the study were to identify morphological characters, identify types of seagrass associated with Halophila spinulosa and present a distribution map of Halophila spinulosa in the Bangka Belitung Islands. The research method for seagrass morphological characters is based on field data in the form of photographs, then compared with identification sources from books and research journals. The seagrass distribution map was determined based on a literature search from 2015 to 2022 and then a map was made using Arcmap 10.8 software. The results of the research on the morphological characters of Halophila spinulosa species can be seen from the shape of the roots, rhizomes, leaves, flowers and fruit. This type of root form is unbranched root (simple root) and each node on the rhizome has one root. Compound leaves are elliptical in shape. These leaves are paired, in opposite positions, located in one plane, arranged obliquely around the stem and have serrated leaf tips. The distribution of Halophila spinulosa seagrass in the Bangka Belitung Islands is spread in the areas of Central Bangka Regency, South Bangka Regency and Belitung Regency. Halophila spinulosa species are often found mixed (associated) with seagrass species Halodule uninervis and Oceana serrulata.

Abstract

Sampur Beach is one of the beaches in Central Bangka Regency with tin mining activities and a fishing area. Heavy metals in the human body can disrupt the work of enzymes and metabolism, causing cancer and mutations. This study aims to determine the status of heavy metal Pb and Cu contamination in the surface sediments of Sampur Beach. Heavy metal analysis uses the Atomic Absorption Spectrophotometry (AAS) method. The research results show that the condition of the sediment texture at Sampur Beach has a sandy to clayey sand substrate (83.09%-94.89%) and has a low Total Organic Matter (BOT) value (0.96-1.54%). The contamination factor values for metals Pb (0.00026 – 0.00036) and Cu (0.00285–0.00298) are low while the enrichment factors are high for metals Pb (95.69-220.44) and Cu (1090.89). –2084.60) which indicates the presence of anthropogenic input in addition to natural input. The geoaccumulation index for Sampur Beach is low for Pb (-12.502 to -12.038) and Cu (-9.042 to -8.975) and the PLI value for Pb and Cu metals (0.00087–0.00103) is not polluted to slightly polluted.

Abstract

The Baturusa River receives input from various activities ranging from industry, mining, fisheries, large-scale plantations and shipping ports. This research aims to determine the concentration of the heavy metals Copper (Cu) and Zinc (Zn) as well as the status of the level of contamination, contamination and enrichment of the heavy metals copper (Cu) and zinc (Zn) in Baturusa Waters, Bangka Belitung Islands Province. Heavy metal analysis using the AAS method. Concentrations of heavy metals Cu and Zn ranged from 0.73-2.29 mg/kg and ranged from 1.45-14.74 mg/kg. The contamination factor values for heavy metals Cu and Zn are included in the low contamination level (CF<1) with a range of Cu 0.016-0.050 and Zn 0.015-0.155. The results of the I-geo value for Heavy Metal Cu range from -4.881 to -6.530 and for Heavy Metal Zn range from -3.273 to -6.618 which shows that the I-geo value (<0) means it is not contaminated with heavy metals. The PLI value ranges from 0.01-0.08, indicating it is not contaminated. The EF value for the heavy metal Zn is greater than for the heavy metal Cu (Zn>Cu), the value for Cu is 2.32-7.54 and Zn 2.59-11.27. The EF values of the heavy metals Cu and Zn are included in the moderate to sufficient enrichment level category. Variations in EF values in the waters of the Baturusa Estuary, Bangka Belitung Islands Province show that there is input from anthropogenic sources at all stations as well as input from natural weathering processes from land (both physical and chemical).

Abstract

In beach tourism development, the decision-making process via the web is a valuable tool that can provide several alternatives for decision-making planners in beach tourism development. The aim of this research is to develop the implementation of a decision support system for selecting WebGIS-based beach tourist attractions in South Lampung Regency. This research is research with the concept of Research and Development, the data used in this research is primary data obtained from field observations and secondary data obtained from the government. Data was obtained through observation and documentation studies from 30 beaches in South Lampung Regency, then processed using the Simple Additive Weighting method. The research results show that bio-physical and managerial factors are the factors that have the most influence on the results of this weighting and are the most dominant supporting alternatives for selecting beach tourist attractions in South Lampung Regency. The recommended beach tourism in South Lampung based on the highest weighting value is Pasir Putih Beach which is the highest ranked, followed by Tapak Kera Beach. Supporting factors such as bio-physical factors, socio-economic factors and managerial factors can be used as primary considerations for beach tourism managers and local governments should continue to develop and innovate in using Simple Addivite Weigting, because the method is much more practical and effective in determining object recommendations beach tourism for tourists.

Abstract

Taxonomically, according to the World Register of Marine Species (WORMS), in 2021 the naming of the species Cymodocea serrulata will change to Oceana serrulata (R. Brown) Byng & Christenh. Many studies have been carried out in the Province of the Bangka Belitung Islands, but this type of distribution map has not been presented in detail. Observation of seagrass in the field allows the identification of seagrasses with other types of seagrass. This study aimed to identify morphology, species distribution, and other types of seagrass often associated with seagrass species Oceana serrulata in the Province of the Bangka Belitung Islands. The methods in this study include data collection, identification, and map making. Morphological identification of seagrass species refers to several identification sources. The distribution map of Oceana serrulata is presented from the seagrass data collection that has been carried out. This research uses data from different times, the first was obtained from 2011 and 2022 as primary data. The results of the study explain the identification carried out on the Oceana serrulata has the same characteristics as identification literature. Similarities seen from the identification of leaf morphology which ribbon curved like, parallel leaf veins and triangular shaped sheaths. Other seagrass species that are most often associated with Oceana serrulata are Halodule uninervis and Enhalus acoroides. The map of the distribution of seagrass species Oceana serrulata is found on the islands of Bangka, Belitung, Anak Air, Lepar, Ketawai, Semujur, Kalimambang, Kelayang, Kepayang, Ruk, and Sebongkok islands.
