Sea Cucumbers belong to the phylum Echinodermata, class Holothuroidea. These creatures are commonly found in areas near coral reefs, sandy waters, seaweed, seagrass beds, and muddy sands. This research aims to identify the various species of Sea Cucumbers in the waters around Molosing Island and Biau Beach, Bolaang Mongondow Regency. Furthermore, the research seeks to determine the nutritional content of the muddy substrate where Sea Cucumbers reside. The study involves observing the form, colour, and patterns (morphology) of Sea Cucumbers and testing the nutritional content of their muddy habitat substrate using proximate analysis with the SNI by difference method. The identification results of the form, colour, and patterns of Sea Cucumbers at Molosing Island and Biau Beach, Bolaang Mongondow Regency, reveal three species of Sea Cucumbers from different genera: Holothuturia and Stichopus. One species on Molosing Island is Holothuria leucospilota, while two on Biau Beach are Stichopus horrens and Stichopus vastus. Proximate analysis of the muddy habitat substrate of Sea Cucumbers includes the following parameters: ash content, protein content, crude fiber content, and fat content.

Indonesia ranks 7th out of ten countries with diabetes mellitus, which continues to increase yearly. Honeycomb is rich in secondary metabolites formed from plant resins (propolis) which contain alkaloids, flavonoids, saponins, tannins, steroids and triterpenes. The research aimed to analyze the comparison of flavonoid content and antidiabetic activity with the enzyme Î±-glucosidase In Vitro nest extract of A. mellifera and A. dorsata Binghami. The samples used were nests of A. mellifera from northern Toraja, southern Sulawesi and A. dorsata Binghami from Southeast Minahasa, North Sulawesi. Using 96% ethanol, HPLC method of flavonoid testing and in vitro antidiabetic activity testing using Î±-glucosidase enzymes. The flavonoid content results were based on the number of peaks produced and the retention time of A. mellifera produced 26 compounds, and A. dorsata Bingham produced 21 compounds. The results of in vitro antidiabetic tests with Î±-glucoside enzyme inhibitors obtained IC50 values from the nest extract of A. mellifera of 3.605 mg/L and the nest extract of A. dorsata Binghami of 4.992 mg/L. The extract from A. mellifera had better antidiabetic potential than that of A. dorsata Binghami, although the difference is insignificant.

Indonesia is known with its high biodiversity. One of them is sea cucumber. Various species of sea cucumbers are found in Indonesian sea in Talaud Regency at Kabaruan Island. Identification of sea cucumbers to reveal the biodiversity of sea cucumbers in Kabaruan Island, which is almost unknown. This research was to identify six samples of sea cucumber (Holothuroidea) in Kabaruan Island based on morphology and DNA barcoding using the COI gene. The differences between each species can be seen from the morphological characteristics, the length and width of sea cucumbers, papillae, pattern and color. The results showed that there were 4 species from 6 samples, which is Holothuria leucospilota, Holothuria whitmaei, Eleutherozoa sp., and Holothuria atra. That six samples with the code A1, A2, B1, C1, and C2 have a homology level of 99%-100% with the target nucleotide sequence from GenBank. Meanwhile, the sample’s code A3 has a homology level of 90% with the Eleutheroza sp. so there is a possibility that sample A3 is a new taxa that has the highest similarity to the Eleutheroza sp. From the six samples, it was found that samples A2 and B1 had the highest level of similarity which is 100%. Meanwhile, the samples with the lowest percentage values are samples A3 and B1 and samples A2 and A3, with a percentage value of 82.75%. There were 4 species from six samples found in Kabaruan Island. There is a possibility that Sample A3 is a new species that is similar to Eleutheroza sp.

The lack of scientific information about the current condition of the mangrove ecosystem on the Molas beach in the Bunaken District of Manado City is an important reason to conduct a study related to the analysis of mangrove forest vegetation. The purpose of this research is to identify the types of mangroves and to find the Important Value Index (INP) of mangroves on the Molas beach in the Bunaken District of Manado City. Data collection was conducted using the line transect method with plots at only one observation station, which was then analyzed to determine the Importance Value Index (INP). Based on the observations, it was found that four types of mangroves were present at the research location. The dominant mangrove species are Bruguiera Cylindrica, Bruguiera gymnorrhiza, Aegiceras cosniculatum, and Ceriops tagal. The substrate condition, which is dominated by muddy sand, and the water quality parameters that affect mangrove growth generally still meet the standards for mangrove growth. The species Ceriops tagal has the highest values of Relative Density, Relative Frequency, and Relative Dominance, resulting in the highest INP. Meanwhile, the lowest INP was found in the species Bruguiera gymnorrhiza in the tree category

The goal to be achieved from this study is to Improve Critical and Creative Thinking Skills, as well as Increase Students' Interest in Learning Biology in Class XI A4 SMA Negeri 1 Airmadidi Through the Application of the Synectics, Mind Maps, Cooperative Learning (SM2CL) Learning Model. The problems in this study are low interest in learning students; Students are more likely to be passive when studying; Teachers have never used learning models that can make students think critically and creatively; Learning is more teacher-centered. The research method used is the Classroom Action Research (PTK) method. The results of the research conducted in class XI A4 of SMA Negeri 1 Airmadidi showed that the acquisition of scores in the first cycle with a classical completion percentage of 38.88% increased to 66.66% in the second cycle. Although the classical completeness did not reach 75%, individually. Namely, 24 out of 36 students got a satisfactory score above the KKM, the highest score of 95, and the lowest score of 85 in cycle II. The score obtained from the learning interest questionnaire in the first cycle was at the percentage of 68% to 70% in the second cycle, and both were in a good category. Then, subject teachers and the school need to consider and evaluate some things, namely, the character of 12 students who did not want to do assignments at all from cycle I to cycle II.

Indonesia is a highly biodiverse country, second only to Brazil. This gives Indonesia enormous potential in ethnopharmacology. Previous studies have shown that the leaves of the Brugmansia suaveolens plant, also known as Angel trumpet, have high antioxidant activity. The aim of this study is to test the antioxidant activity of B. suaveolens flowers and conduct quantitative screening to determine which compounds play the greatest role in their antioxidant activity. This research used the DPPH test and Gas Chromatography-Mass Spectrometry (GC-MS) screening. Ascorbic acid was used as the comparator in this study. Before the DPPH and GC-MS testing, the samples were extracted using the cold maceration technique with a 95% ethanol solvent. Then, the samples were concentrated using a rotary evaporator. The IC₅₀ value of the ethanol extract of B. suaveolens flowers is 196.16 µg/mL, while the IC₅₀ value of ascorbic acid, the comparator, is 3,814 µg/mL. This result shows that the ethanol extract of B. suaveolens flowers has moderate antioxidant activity. Screening bioactive compounds with GC-MS showed that Hexadecenoic acid and Octadecanoic acid play the biggest role in antioxidant activity. However, the compound with the highest content in the ethanol extract of B. suaveolens flowers is scopolamine.
