Abstract

Mastigias papua is a jellyfish that is trademark of marine lakes. Ongeim’l Tketau Lake in Palau, Hang Du I Lake in Vietnam, Kakaban Lake in Kalimantan, and Lenmakana Lake in Raja Ampat Papua are exotic tourist destinations because of presence of these biota in the lake. Water temperature is very influential on the life of a jellyfish because of its mutual symbiosis with brown algae zooxanthellae. Mastigias has totally disappeared in several places due to water temperature increasing, including Lenmakana Lake in the West Monsoon 2017/2018 and 2018/2019. The absence of Mastigias in this lake will be explained by recorded logger data installed in the lake and at sea. Secondary data from NOAA and BMKG will be used to explain the condition of absence of jellyfish. Water lake temperature data showed an increase to 2.5oC when the Mastigias disappeared. Temperature increasing occur due to seasonal cycle patterns of lake water temperatures and weather cycles which change in time, the dry season occurs faster and the rainy season occurs slower. Conversely, in the West Monsoon 2019/2020, Mastigias still found in the lake. The rainy season which is 20 days faster than normal condition helps reduce the heat in West Monsoon.

Abstract

ABSTRACTMangroves are one of the most important natural resources in coastal areas. Availability of various types of food that are on ecosystems is already making its presence as a local nursery, where searching for eating and also serve as a regional tourist ecosystem of mangrove. In use as Regional tourist mangrove need to attention the condition of the physical environment and the distribution pattern of zoning. Research is carried out in the month October to November 2019 in the village of Juanga Regency island of Morotai. Data zoning mangrove using the method of the combination is to combine the methods of plots to track transects, to determine the four stations of observation of each respective stations and each station is divided into three zones: zone front, zone of middle and zone back starting from the point of the outermost growth of types of mangrove constituent primary to the point of transition between sea and land. The research results of the study found 5 types of mangroves namely Rhizophora mucronata, Ceriops decandra, Rhizophora apiculata, Xylocarpus granatum and Sonneratia alba. The distribution of zoning patterns in the front zones of station I and the middle zone is dominated by Rhizophora mucronata and Rhizophora apiculata types, the rear zone is dominated by Ceriops decandra. Station II front zone is dominated by Sonneratia alba, middle zone (Rhizophora mucronata), rear zone (Ceriops decandra). At station III the front zone (Rhizophora apiculata), the middle zone and the rear zone (Ceriops decandra) while at station IV the front zone, the middle zone and the rear zone are dominated by the Ceriops decandra type.

Abstract

Seagrass ecosystem have primary and secondary productivity with great support to the abundance and diversity of fishes and it’s biota associations. Seagrass ecosystems are also as a coastal resources that have an important role of environmental services. Some community activities will directly or indirectly can have an impact on habitat degradation and biodiversity of seagrass ecosystems. The importance oto assess the potential of seagrass ecosystem and it’s biotas association is to know of sea grass’s role to provides of environmental services is the aim of this study. This research was conducted in the waters of Kampung Aisandami, Teluk Wondama Regency during June - July 2019. Data collection methodology was used is structured random methods quadrant transects at two observations to reveal data on seagrass community structure. The datas obtained were tabulated and displayed in tables and figures. Thalassia hemprichii and Enhalus acoroides were found at two observation sites. Another type found outside the observation transect is Halophila ovalis. E. acoroides seagrass species have a frequency value is 0.77 which shows that distribution of E. acoroides is wider than T. hemprichii which has a frequency is 0. 58. Both of station show that T. hemprichii has a frequency value of 0.7 where it indicates that distribution is wider compare with E. Acoroides. T hemprichii has the highest relative density at both observation stations. The status of seagrass of both stations is classified as poor or unhealthy with seagrass value ≥ 30-59.9%. The highest importance index is the T. hemprichii seagrass at both stations and has a higher role than the E. acoroides. The community-based management model is the a suitable model that can be used to developing coastal ecosystem management including seagrass ecosystems in this village.

Abstract

Sea urchin Tripneustes gratilla is multifunction organism that can be used as potential food source because of its high nutrient content. This organism can also be utilized bioindicator of sea waters and as a modal of organism for studying biology’s purposes. The purposes of this research is studying Filogenetic of sea urchin T. gratilla from waters of Wasior and Serui. The research has been doing at the Biotechnology Laboratory of the state of University of Papua on November to December 2009. The sample was extracted by using Chelex 10 % and was amplified with PCR technic (polymerase chain reaction). Sequencing of CO I gens (cythocrome oxidase subunit I) was done using sequencher ABI 377 (Apllied Biosystem). The result of nucleotid sequence data was analyzed utilizing MEGA 4.0.2. This researchs result showed that the gen fragment that was succesfully amplified 601 bp. The sequence result of nucleotid which was analyzed the variaty of nucleotid between the sample from two waters. Filogenetic analyzing toward individu of the two waters produce the two clusters. The first cluster consist of SER 01 and sub cluster which is consisted of WSR 02 and SER 02. While, the second cluster consist of only WSR 01. This result showed that every individu from Wasior (WSR 02) has close genetic relation with other individu from Serui (SER 02), that proved there is genetic flow between the two waters.

Abstract

This study was purposed to identify the spesies and the community structure of gastropods in Manokwari shore. The sampling used transect method at two observation stations, i.e Briosi BLK shore and Rendani shore. Each station has three transect lines parallel to the sea, each of which had 10 quadrats. These transects were placed on a seagrass beds. Data analysis was carried out including diversity index (H’), evenness index (E), dominance (D) and density of gastropods. The results showed that the water quality at both sampling locations could support the growth of gastropods. The species composition of the gastropods in two sampling locations consisted of 20 families, 28 genera, and 82 species. The diversity index (H’) in Briosi BLK shore was 3.14; evenness index (E) = 0,92; dominance (D) = 0,06 and density of gastropods 23,70 ind.m-2. The diversity index (H’) of gastropods in Rendani shore was 3,79 ; equitability index (E) = 0,90; dominance (D) = 0,03 and density of gastropods 83,33 ind.m-2 . Gastropods found were Strombus (Canarium) urceus urceus, Conus (Virroconus) coronatus, Chicoreus sp.2, Vexillum (Costellaria) mirabile, Polinices tumidus, and Imbricaria conularis. Based on the diversity index, the two stations are in a high diversity index so that there is no dominant species in the two locations, The gastropod density in Rendani shore was higher than that in Briosi BLK, it is suspected that the substrate is suitable and the amount of organic matter and then, far from the gathering place to support the growth of gastropods.

Abstract

Taman Nasional Teluk Cenderawasih (TNTC) memiliki potensi karang sebanyak 145 jenis dari 15 famili, dan tersebar di tepian 18 pulau besar dan kecil. Namun kondisi ekosistem terumbu karang di TNTC mulai terancam akibat fenomena alam dan aktifitas manusia. Penelitian ini bertujuan untuk mengetahui kondisi tutupan karang di TNTC berdasarkan bentuk pertumbuhan (lifeform) karang. Penelitian dilakukan dengan metode Point-Intercept Transect (PIT) pada Bulan Mei 2012, dengan pengambilan data terumbu karang per titik (point) sepanjang transek. Penempatan garis transek dilakukan pada 30 stasiun penelitian pada kedalaman 9 - 10 meter. Hasil penelitian menunjukan bahwa persen tutupan karang berdasarkan bentuk pertumbuhan (lifeform) karang hidup berkisar 44 %, karang mati 15%, pasir 31 %, alga 8% dan OT (others) 2%. Kisaran persentasi tutupan karang hidup antara 31 - 50 % sehingga dikategorikan kondisi sedang. Kondisi tutupan karang tidak jauh berbeda antara zona larang tangkap dan zona tangkap. Penelitian ini mengindikasikan pula bahwa diperlukan pengawasan pada zona larang tangkap karena masih ada masyarakat yang menangkap ikan menggunakan alat tangkap yang merusak di TNTC.

Abstract

Saporkren village at Raja Ampat Islands is well-known for international and domestic icons for community based ecotourism in West Papua Province. This research is designed to investigate the levels of participation, functions and intensity of five groups of respondents (leader, interested group, family members, women, and teenager), influenced factors and benefits received from participation are also investigated. The results indicated that levels of participation of five groups of respondents are classified into extremely inactive (1-25) with an average for their index PEI of less than 25, and levels of participation for children are absent. Leaders had function in planning with intensity for total control and decision making. Other respondent of interested groups, family members and women had funstions in implementation, maintenance, and distribution with intensity for decision making, consultation, and information. However, five groups of respondents are absent in management function and initiation action of intensity involvement. Counseling from official government (70.8%), invitation from local officer (41.7%), and income generating (37.5%) are three main factors influenced the local community interested in ecotourism participation. Various direct and indirect benefits from ecotrourism management are confirmed such as famous ecotourism destination, local entrepreneur (homestay, handycraft, local cuisine), tour guides, local nature conservation guards, motorist, and the others. Three important issues for ecotourims based community in Saporkren village are management, initiation action, and absence of the teenagers in levels of participation.

Abstract

Coral reefs are one of the invertebrates that inhabit an ecosystem, and there is various aquatic biota. Coral reef ecosystems have an essential role both ecologically for aquatic biota and physically as a barrier to sea waves leading to coastal areas. Artificial reef media (bioreeftek) is a new technology in developing of transplantation methods using natural materials such as coconut shell waste and bamboo. The research objective is about the resistance level of the design of coral growth media (bioreeftek). This research was conducted from August to October 2020 by designing the coral reef bioreeftek media, starting with studying the bioreeftek media design method, collecting tools and materials, to making and placing the media in a predetermined location. Making bioreeftek media as many as eight media, with 81 bamboo poles (9 poles for one medium) and 243 coconut shells were prepared. From the observations' results when placing and the first observation to the second observation with the integrity of 100%, which indicates a reasonably efficient media construction.

Abstract

The presence of skipjack fish resources in a fishing area is related to the suitability of the environmental conditions of the waters. This study aims to examine the relationship of sea surface temperature (SPL) to skipjack catches and the characteristics of skipjack catches in Manokwari waters. Data, both catch data and sea surface temperature data, are collected through field surveys by following fishing operations. Furthermore, the data were analyzed descriptively using graphs and mathematically like von Bertalanffy's growth model. The results of this study found that the very small variability of SPL could not explain the variation in the volume of fishermen's catches in Manokwari waters. However, a high SST during the May - August 2013 period is thought to affect the size of the skipjack caught, where the average size of the fish caught inhabited areas near sea level. In addition, the growth of skipjack fish in Manokwari waters is relatively fast with a growth coefficient of 0.42 per year1 and natural mortality between 0.79 per year and 0.81 per year.
