This research is motivated by the lack of studies and absence of research data on the diversity of Echinoderms on the Beach of Ranowangko II Village, Kombi District, Minahasa Regency. The aim of this study is to determine the diversity of the phylum Echinodermata found on the Beach of Ranowangko II Village, Kombi District, Minahasa Regency. Sampling in this research used the quadrat transect method with 3 transect lines, each line being 100 m long, and 10 quadrats, each measuring 1 x 1 m². The results of the study found 4 classes and 5 species including the class Asteroidea (Protoreaster nodosus), class Ophiuroidea (Ophiocoma scolopendrina), class Echinoidea (Tripneustes gratilla), class Holothuroidea (Holothuria atra & Holothuria vagabunda), and there were 21 individuals, and the dominant species is Holothuria atra from the Holothuroidea class of which there are 11 individuals, indicating that the diversity index (H’) of the phylum Echinodermata on the location is moderate with a value of 1.204. These findings offer initial insights into the condition of the local ecosystem, classified as moderate, and may serve as a foundational reference for long-term ecological monitoring.

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.

Pakoba fruit is often made into sweets, salad, pickles because it has a very sour taste and is a habitat for lactic acid bacteria. The purpose of this study was to determine the characteristics of lactic acid bacteria succession during the fermentation process of candied pakoba fruit. This research is an explorative research. The number of microbes was observed starting from day 0, 1, 3 and 7. Based on the results of identification data, 12 bacterial isolates were obtained in pakoba fruit fermentation. The isolates obtained were then macroscopically identified and microscopically identified. 12 isolates were round, 12 isolates had enpitire edges, 12 isolates had raised elevations, 12 isolates had covex colony surfaces, 10 isolates were white and 2 isolates were cream-colored. Of the 12 isolates, it was found that the bacteria that grew in the fermentation of candied pakoba fruit after profile matching was suspected of the genus Lactobacilus sp. and Leucunostoc.

The application of the conversion results from Eco-Enzyme into dishwashing soap, the fermentation process lasts for one months, where the resulting liquid is dark brown in color and has a very strong sweet and sour fermented aroma. There is a lack of public knowledge about the very profitable benefits of Eco-Enzyme, such as as a multi-purpose cleaner as a multi-functional liquid which can be converted, one of the ways, into dishwashing soap. This research aims to determine the application of the results of converting Eco-Enzyme into dishwashing soap. This research used experimental methods and a research period of 3 months. This Eco-Enzyme is made with a ratio of organic ingredients: sugar: water 3:1:10. The Eco-Enzyme harvest is converted into dishwashing soap by adding lerak and Methyl Ester Sulfonate (MES). Eco-Enzyme conversion soap was then applied to several treatment groups: plastic plates, cans and glass. The results of the application show that the dishes washed with Eco-Enzyme using lerak have not completely removed dirt, oil and odors in each treatment, whereas Eco-Enzyme using Methyl Ester Sulfonate (MES) when compared with Sunlight brand liquid soap sold on the market shows that there are similarities both in terms of cleanliness, tapestry and smell. The research conclusion is that the application of the Eco-Enzyme conversion results has significant potential to be developed into an active ingredient for environmentally friendly dishwashing soap.

Suatu kegiatan pengabdian kepada masyarakat pendanaan skema Pemberdayaan Kemitraan Masyarakat (PKM) telah dilaksanakan di desa Libas Pulau Bangka Kecamatan Likupang Timur Minahasa Utara dalam upaya mengatasi masalah rendahnya nilai ekonomi jambu mete karena produk utamanya hanya kacang mete kering dengan kemasan seadanya serta pemasaran langsung diantarkan kepada pedagang pengumpul di daratan Likupang. Pengemasan yang hanya menggunakan kantung pastik direkatkan dengan panas api lilin tentunya tidak dapat menjamin kualitas produk dan dapat bertahan lama. Melalui kegiatan PKM telah diaplikasi teknologi pengolahan jambu (kacang) mete dengan kemasan standar dan beragam produk olahan kacang mete serta dengan pemasaran digital. Metode pendekatan yang diterapkan yaitu diaplikasi Teknologi Tepat Guna dengan teknik pendekatan pembelajaran orang dewasa (Andragogik). Hasil kegiatan yang dicapai yaitu (1) terfasilitasi upaya peningkatan pengetahuan dan keterampilan mitra mengolah aneka produk kacang mete; (2) terfasilitasi peningkatan pengetahuan dan keterampilan mitra memproduksi dan mengemas aneka produk kacang mete menggunakan vacuum sealer dengan plastic vacuum emboos; (3) Dihasilkan empat produk olahan kacang mete meliputi kacang mete kering, mete goreng mentega, mete goreng asam manis, dan mete goreng pedas manis, (4) Terfasilitasi upaya meningkatkan pengetahuan dan keterampilan pemasaran digital bagi Mitra; (5) Terfasilitasi satu aplikasi pemasaran digital.

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.
