Abstract

Tulehu State Beach is a bay area which has quite busy activities because there is a port which is the sea gate of Tulehu State. This is suspected to have caused the coastal area of Tulehu to experience a decline in water quality and was polluted. Marine biota is an indicator of the quality of coastal waters that can provide information on the state of these waters in good condition or not. This study aims to determine the number and types of marine biota on the coast of Tulehu State Beach, Salahutu District, Central Maluku Regency and the pollution status of the coast of Tulehu State Beach based on marine biota as bioindicators. This research was conducted in February 2020 - March 2020. The method used in determining the location is purposive sampling which is divided into 3 stations based on the representation of different characteristics in the study location. Data analysis uses the Shannon-Wiener Diversity Index, Uniformity Index and Dominance Index. The results showed that there were 6 marine biota families, namely Littorinidae, Potamididae, Nerithidae, Muricidae, Portunidae and Pectinidae with 592 individuals. The status of pollution of the coast of the State of Tulehu shows polluted, unstable communities and there are species that dominate.Keywords: Pollution; Marine biota; Diversity; Bioindicator

Abstract

The role of mangroves in mitigating climate change is realized through their carbon storage capacity, but deforestation carried out for the expansion of the Tulehu pier threatens the existence of these carbon reserves. This study aims to estimate mangrove vegetation carbon stocks based on aboveground biomass and belowground biomass in Tulehu Waters, Central Maluku. Sampling was conducted using purposive sampling using a non-destructive allometric model on a 10 x 10 m plot. Aboveground and belowground biomass were calculated and then converted into mangrove carbon stocks. Data evaluation was carried out by measuring mangrove biomass and carbon stocks in the Tulehu Waters. Research findings show that the average carbon reserves of mangrove vegetation are the highest on the surface were found at station II (17,571 tC/ha), and underground were found at station (15,222 tC/ha). These findings confirm that mangrove vegetation in Tulehu Waters has significant potential as a carbon sink and support conservation strategies and sustainable coastal management.

Abstract

Extraction of active compounds from plants requires a lot of raw materials. Therefore, other alternatives are needed that can produce active compounds in a relatively fast time. One of them is the use of endophytic fungi. Endophytic fungi live in plant tissues including pulai (Alstonia scholaris) which is used as an ingredient in herbal medicine. Endophytic growths can create auxiliary metabolite intensifies that are like their host plants. The point of this examination was to decide the sorts of endophytic growths found on pulai leaves and their antibacterial action. This research is a qualitative research, where microscopic characteristics of fungi are observed using the slide culture method and antibacterial activity is tested using the modified Kirby Bauer method. The results of this research found 8 isolates of endophytic fungi, consisting of Neurospora sp1, Neurospora sp2, Paecilomyces sp, Acremonium sp, Fusarium sp, and 3 unidentified isolates. All endophytic fungi found on pulai leaves can inhibit the growth of Staphylococcus aureus and Escherichia coli with the highest inhibition zone diameter found in isolate K8 (Acremonium sp) at 3 cm for S. aureus and isolate K7 at 1.8 cm for E. coli.

Abstract

Pollution in Kayeli Bay is from the Marlosso and Nametek rivers. This area forces full adaptation of biota, including the seagrass Enhalus acoroides. This study aimed to compare changes in the anatomical  structure and physiological response of the seagrass Enhalus acoroides. The preparation method uses a modification of the Ruzin method. Measurements are made using a microscope equipped with a micrometer and a spectrophotometer. The results showed that the thickness of the root epidermis and endodermis in the Marlosso area was 5.77 μm and 2.3 μm; and in Nametek, epidermis 5.58 μm and endodermis 1.54 μm. The epidermis and endodermis of the Marlosso rhizomes are 9.98 μm and 3.5 μm. Nametek rhizomes are 6.62 μm and 3 μm. The leaf tissue in Marlosso, namely the adaxial and abaxial cuticle, is 0.57 μm, the adaxial and abaxial epidermis is 2.84 μm and 2.78 μm, the thickness of the epidermis and cuticle is 10.2 μm and 1.81 μm. Nametek Waters are 0.45 μm and 0.54 μm, and the adaxial and abaxial epidermis are 1.62 μm and 2.29 μm. It was concluded that there was thickening of the cell walls in all tissues in the Marlosso River, and showed lower chlorophyll content compared to Nametek.
