Abstract

Nowadays, modern society's activities are mostly carried out outside, so the harmful effects of changes in temperature, exposure to UV radiation, pollution and air humidity, namely a decrease or even loss of skin moisture, cannot be avoided. If untreated, reduced moisture in the skin will not only make the skin scaly, but will also cause irritation or injury to the skin. This research aimed to test the moisturizing effect of the best body lotion formula and also test irritation and hedonics. This test had received ethical approval and was carried out on the same panelists and the moisturizing effect of the preparation was measured using a skin moisture analyzer. The results obtained show that the formulation could increase the moisture of the panelists' skin by 56% and irritation testing showed no redness and swelling. So it can be concluded that the cinnamon extract body lotion formula had a moisturizing effect and not irritating so it was harmless to apply on the skin.

Abstract

The intertidal zone is a crucial habitat for various marine organisms, including Mollusca. Mollusca serve as bioindicators for assessing water quality. However, data on mollusc diversity in the coastal area of Bahowo Beach is still limited. Therefore, this study aimed to improve the knowledge of Mollusca diversity in this region. Molluscs were collected using 1×1 m plots placed randomly along vertical stratification. The samples were preserved in 70% alcohol and transported to the laboratory for identification using an identification guidebook. The assigned Mollusca were then analysed using Paleontological Statistics (PAST) software. The study recorded 79 individuals representing 41 species from two classes: Gastropoda and Bivalvia. The order Neogastropoda was the most dominant, with 22 species. The most abundant species was Littoraria scabra, with 16 individuals. The diversity index (H' = 3.209) falls into the high category, indicating that the Bahowo Beach ecosystem remains in good condition and continues to support mollusc life. Zona pasang surut merupakan habitat penting bagi berbagai biota laut, termasuk Mollusca. Mollusca berperan sebagai bioindikator untuk menilai kualitas lingkungan perairan tersebut. Data mengenai keanekaragaman Mollusca di wilayah pesisir Pantai Bahowo masih terbatas, sehingga dilakukanlah penelitian ini untuk menambah informasi mengenai keanekaragaman jenis Mollusca. Pengambilan Mollusca dilakukan dengan menggunakan plot 1×1 m secara acak, sampel yang diperoleh dimasukkan ke dalam plastik berisi alkohol 70% kemudian dibawa ke laboratorium untuk diidentifikasi menggunakan buku identifikasi. Mollusca yang telah diidentifikasi akan dianalisis menggunakan perangkat lunak Paleontological Statistics (PAST). Hasil Penelitian ini ditemukan 79 individu dari 41 spesies dari 2 kelas yaitu Gastropoda dan Bivalvia, dengan dominasi ordo Neogastropoda (22 spesies). Spesies terbanyak adalah Littoraria scabra (16 individu). Indeks keanekaragaman (H' = 3.209) menunjukkan kategori tinggi, yang menandakan ekosistem Pantai Bahowo masih dalam kondisi baik dan mendukung kehidupan Mollusca.

Abstract

The city of Manado is surrounded by waters with a long coastline. Most of the coastline is used for human activities. These activities include tourist attractions, ports, and trade centres. The sustainability of these sectors is highly dependent on the health of the marine ecosystem. One organism that plays an important role in the aquatic ecosystem is zooplankton. This study aims to calculate the density of zooplankton and analyse its functional role. The method used was exploratory descriptive, which is a research pattern that describes in detail or comprehensively the condition or status of zooplankton phenomena. This study was conducted at Bahu Beach and Meras Beach, North Sulawesi. The density value at Bahu Beach is 307.35 ind/m3 and at Meras Beach is 222.4 ind/m3. Zooplankton identified from two sampling points belonged to the phyla Arthropoda, Foraminifera, Annelida, Mollusca, and Cilliophora. The total number of genera found was 22. There were 1,032 consumer I individuals, 798 consumer II individuals, and 193 consumer III individuals.

Abstract

Gastropods play an important role in maintaining the balance of coastal ecosystems, particularly as detritivores that support nutrient cycling. Pantai Meras, located in North Sulawesi, has a complex coastal ecosystem that includes mangrove forests, seagrass beds, and coral reefs, which support high biodiversity. However, information regarding gastropod diversity in this area remains limited. This study aims to identify gastropod species and analyze their diversity levels in the waters of Pantai Meras. A purposive sampling method was used for data collection, employing 0.5 m × 0.5 m plots placed randomly at 45 sampling points across three research stations with different substrate types, namely sandy substrate (Station 1), muddy sand substrate (Station 2), and sand mixed with coral fragments (Station 3). Data were analyzed using PAST software version 4.17 to calculate the Shannon diversity index (H’). The results showed a total of 243 gastropod individuals belonging to 89 species from six orders, with Neogastropoda being the dominant order, comprising 59 species. The most abundant species was Nassarius globosus, with a total of 26 individuals recorded. The overall Shannon diversity index (H') was 4.14, which falls into the high diversity category. The highest H' value was recorded at Station 1 (4.08), followed by Station 3 (4.02), and the lowest at Station 2 (3.43). The high gastropod diversity at Pantai Meras indicates that the coastal ecosystem in this area is still in good condition and capable of supporting sustainable gastropod populations. Environmental factors such as temperature, salinity, as well as the presence of mangroves, seagrass beds, and coral reefs contribute to the high species diversity of gastropods in the study area.
