Abstract

Acropora halmahera is one of the coral species that has an important role in the coral reef ecosystem Wolstenhome (1998) found in Loloda Island. A. halmahera is an endemic species found in the Halmahera sea. This coral species has not yet received information about the distribution in the marine area of the North Maluku archipelago. Habitat influences morphogenetics. Information on the general description of the habitat of this species has not been found (unpublished). A. halmahera is a coral species that ecologically also plays a role in influencing sedimentation rates and serves as a place for marine organisms to live. The study aims to describe the habitat of A. halmahera in Small Islands, North Maluku. Data collection of Acropora halmahera and coral life forms on three islands using Line Intercep Transect (LIT). Samples of A. halmahera were taken 32 cm branch. Morphometric measurements of A. halmahera were conducted in the laboratory. Environmental variables were takenwas conducted to see the relationship of the environment to the station. The results showed that A. halmahera has a habitat preference at a depth of 5-20 meters, temperature 29-33 C, salinity 32-35 ppt, and pH 7.1-8. Sandy bottom substrate conditions for the growing area of A. halmahera species. PCA analysis showed that each station characterized environmental variables. Data showed that 13 coral life forms were found with variations in coral cover at each station. The environment was generally favorable for species to grow and thrive. These findings provide useful insights for coral reef conservation and management in the Halmahera region, and can serve as a reference for further research on other coral species.Keywords:EndemicArchipelagoBranching CoralMorphologySmall Island

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

North Maluku Province is an archipelagic province that has a sea area of 113,796.53 km2 or 70% of the land area. As an archipelagic area, North Maluku waters have high biodiversity. One of the important biota in North Maluku waters is the eel. Eel is one of the water resources that have high economic value, because of its nutritional contentEel (Anguilla sp) is a catadromous fish that begins its life in the larval or juvenile phase in marine waters and grows up in brackish and fresh waters. This study aims to determine the distribution of eel species (Anguilla sp) in the seas and the morphometric eel (Anguilla sp) in kayoa waters. The results showed that the number of eels found at both stations was 13 tails. The results of the morphological analysis showed that the type of eel found at both stations was A. marmorata, the morphometric identification results showed that at station 1, the total length range was 50 - 106 cm, with a weight of 460-4100 grams, while at station 2 obtained a length range of 65 cm - 83 cm, with a weight of 79 -1300 grams. Key Word: Area, Morphometri, Anguilla, Small Island, Tropis

Abstract

Produk gerabah spesifik di produksi oleh pengrajin di Pulau Mare adalah “Vorno” atau “keta”. digunakan sebagai alat pengolahan pangan tradisional “sagu lempeng”. Dalam perkembangnnya industri gerabah mengalami kendala kebutuhan material serta inovas kreatit menjawab kebutuhan konsumen. Oleh karena itu perlu upaya mengkaji potensi penyimpanan panas dari gerabah yang terbuat dari material Alluvial dengan harapan ditemukan (eksprimental) komposisi gerabah dari material alluvial hutan mangrove dan pasir yang mempunyai karakter penyimpanan panas yang tinggi sekaligus sebagai salah satu langkah strategis dan mendesak untuk dilakukan dalam upaya pengembangan kerajinan gerabah tradisional dengan memperbaiki mutu produksi dan menciptakan model-model desain yang inovatif. Hasil uji coba pembuatan gerabah dengan memanfaatkan materuial alluvial hutan mangrove, dapat ditarik beberapa kesimpulan sebagai berikut : 1) Komposisi material dengan kadar pasir lebih besar berpeluang mengalami kehancuran lempengan saat dilakukan pembakaran; 2) Komposisi gerabah perlakuan A (50 %: 50 %) mempunyai penyusutan dimensi lempengan yang lebih baik ( 20 %) dibandingkan perlakauan C (30%:70%) dan perlakuan D (80% : 20%). 3) Kecepatan perubahan suhu lempengan gerabah dari perbandingan material pasir dan alluvial hutan mangrove 50 %: 50 % (perlakukan A) lebih lambat mengalami penurunan suhu (-8, 52oC/2 menit) dibandingkan pada perlakuan C (-11,07 oC/2 menit) dan perlakuan D (-13,12 oC/2 menit). 4) Komposisi lempengan gerabah yang diuji dari material alluvial hutan mangrove mempunyai kapasitas penyimpan panas yang ditinggi dibandingkan dengan material gerabah (vorno)  yang sebenarnya.Kata kunci : Alluvial, mangrove, Vorno, sagu lempeng, lempengan, kapasitas panas

Abstract

Abstract Ternate Island is located on the North Maluku Sea. The North Maluku Sea region includes the Wallacea area and the world's coral triangle. One of the organisms commonly found in this sea is red algae. Study aimed to determine the red algae species by phylogenetic tree analysis based on the rbcL gene as a DNA marker. The preserved red algae tissue samples were extracted with the Geneaid GP100 DNA Extraction Kit Plant. The DNA sample was amplified and then visualized by 1% agarose gel electrophoresis. The amplicon products were sequenced and then aligned with the rbcL gene database that was available at the NCBI gene bank. The phylogenetic tree was constructed using the UPGMA method. The results showed that red algae were identified into four species: namely Gibsmithia hawaiiensis (98.65%), C_rbcL sample was identical to Amansieae sp. (91.50%), D_rbcL sample was identical to Peyssonnelia sp. (95.54%), and G_rbcL sample was similar to Portieria hornemanniI (96.15%). Based on phylogenetic tree analysis, Gibsmithia hawaiiensis from North Maluku is closely related to species from Raja Ampat, West Papua, Indonesia, followed by the Philippines species. Special findings were found to carry out phylogenetic reconstructions that can answer inter-species kinship. The general finding is that the markers used can be used for phylogenetic construction. Phylogenetic construction of Peyssonnelia sp. in North Maluku is related to species from South Africa. North Maluku's Portieria hornemannii is closely related to a species from Korea. Highlight Research This study provides initial information about the DNA barcoding of red algae. Important for management purposes and determining the status of red algae in the future. This scientific information also provides an understanding of the relationships among red algae species in the world's oceans. Global warming has changed the temperature of seawater and affected the population of marine organisms.
