Abstract

Binocular light microscopy (BLM) is an excellent match for a scanning electron microscope (SEM) and a trinocular light microscope equipped with a micrometer (TLM). The practicality, user-friendliness, and short-time analysis of BLM make this method a good choice for spicule analysis. However, its effectiveness and accuracy are yet to be confirmed. This study aimed to validate the effectiveness of BLM by comparing its usefulness to both TLM and the gold standard methods. BLM was first subjected to measuring megascleres and microscleres of 2 sponges. Then, by using the If function built-in Excell and t-test in SPSS 16.0, the compatibility of BLM was evaluated against SEM by measuring the length of spicules from 4 Sangihe sponges and their counterpart species from different locations. Furthermore, the t-test analysis was used to validate the compatibility and effectiveness of our method to the TLM by measuring the spicules of four sponges. Both the F-function and the t-test analysis proved BLM was compatible with SEM with both measurements showing a perfect match for megascleres typed spicules of 4 compared sponges. This new technique also showed a perfect match with SEM (p = 0.367, t-test) and with TLM (p = 0.963, t-test). Keywords: Spicules, sponges, SEM, Wallacea, biomaterial, sponge taxonomy

Abstract

Treatment of Streptococcus mutans infection is generally done using antibiotics or chemical mouthwash, but long-term use can cause bacterial resistance and side effects for health. Therefore, it is important to find alternative treatments that are safer and more effective, one of which is through the use of medicinal plants. One plant that has potential as a source of antibacterial compounds is seagrass (Enhalus acoroides), which has been recognized in various studies to contain bioactive compounds such as flavonoids, saponins, and tannins, which can function as antibacterial agents. The purpose of this study was to determine the antibacterial activity of E. acoides extracts extracted with different solvents against S. mutans bacteria. The design used in this study is a completely randomised design (CRD) model. Testing the inhibition zone of E. acoroides using piper disc diffusion method with different concentrations of 25%, 50%, 75% and 100% with three replicates. Inhibitory zone diameter data were analyzed used ANOVA significant test and differences between treatments, and test of Real Honest Differences (BNJ) was conducted. Methanol and ethyl acetate extracts of E. acoroides can inhibit the growth of S. mutans bacteria that cause dental caries, and ethyl acetate has a stronger effect than methanol at higher concentrations.

Abstract

Country Tengah-Tengah is a coastal village characterized by a hilly highland topography, where the majority of the population are engaged in fishing as their primary livelihood. During times of abundant fish supply, all catches are typically sold in the market and are not retained for household consumption. However, when fish become scarce due to adverse weather conditions, the community tends to seek alternative protein sources such as tofu and tempeh as substitutes for fish, and some individuals even opt not to consume fish. There are also those who have a lesser preference for fish consumption. The aim of PKM is to provide education on fishery product processing as part of efforts to strengthen protein-based food security by introducing processed fish products. This is intended to enhance the community's understanding of the importance of fish consumption. The methods employed in this activity include lectures, discussions, and training sessions. Lectures are delivered in the form of power point presentations and leaflets, followed by question and answer sessions. The target audience comprises members of the PKK and housewives in County Tengah-Tengah, Central Maluku. Following the educational sessions, there was an increase in knowledge levels among the participants, transitioning from ignorance to awareness. Participants acknowledged their satisfaction with the wealth of information provided, covering topics such as the benefits of fish and its nutritional content, fish processing techniques, product diversification, preservation methods, quality control, surimi production, application of surimi in various fish products, and proper packaging techniques. It is expected that through this activity, the community will be able to produce surimi products according to their characteristics and be motivated to create diverse and high-quality processed fish products. This initiative aims to increase the added value of fish, address the scarcity of fish during certain seasons, and contribute to additional income generation for the residents of Country Tengah-Tengah.
