Abstract

The mint plant (Mentha piperita L.) is one of the many aromatic herbal plants that produce essential oil commonly known as peppermint oil. Meanwhile, the soka flower plant (Ixora paludosa L.) is an ornamental plant that fills the planting elements with fast growth and beautiful, vigorous plants. This study aimed to assess the effect of lime insecticides combined with mint leaf extract (Mentha piperita L.) and soka flower extract (Ixora Paludosa L.) on red fire ants (Solenopsis invicta). This study used four red fire ant samples (Solenopsis invicta), which were divided into five treatment groups: X1 (75% mint leaf extract and 25% soka flower extract); X2 (75% soka flower extract and 25% mint leaf extract); X3 (50% soka flower extract and 50% mint leaf extract); Negative control (lime base); and Positive control (branded lime). The sample size for this study was 80 red fire ants (Solenopsis invicta), with each control group consisting of four fire ants, and the experiment was repeated four times. The Kruskal-Wallis test was used to analyze the data, revealing significant differences between the treatment groups. Therefore, the researchers concluded that the administration of 50% mint leaf extract and 50% soka flower extract effectively disrupted the activity of red fire ants

Abstract

Ranowangko II beach is famous for its beautiful beaches and is a natural habitat for macroalgae, including Caulerpa racemosa and Sargassum polycystum. Despite its great potential and abundance, information about the nutritional content of both types of algae, especially in the Ranowangko II beach area, is still limited. This study aimed to determine the nutritional content (water content, ash content, protein, lipid, crude fiber, carbohydrate) of green algae Caulerpa racemosa and brown algae Sargassum polycystum in Ranowangko II beach. The type of research used is descriptive quantitative to determine the proximate nutrient content of two types of algae tested by proximate analysis in the laboratory. Based on the study results, there were variations in the nutritional content of the two types of algae tested. Green algae Caulerpa racemosa has a moisture content of 71.29%, ash content of 6.90%, protein of 2.78%, fat of 1.34%, crude fiber of 3.53%, and carbohydrates of 17.69%. Brown algae Sargassum polycystum has a water content of 83.23%, ash content of 1.82%, protein of 9.93%, fat of 1.72%, crude fiber of 11.18%, and carbohydrates of 3.30%. The conclusion obtained after conducting this research is that Caulerpa racemosa (green algae) and Sargassum polycystum (brown algae) have different nutritional content.

Abstract

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 Beach of Ranowangko II Village, Kombi District, Minahasa Regency is moderate with a value of 1.204.

Abstract

This research aims to provide information on the types, and diversity of macroalgae in seagrass ecosystems and water conditions in the waters of Ranowangko Dua Village Beach, Kombi District, Minahasa Regency. Observations of macroalgae in seagrass ecosystems were carried out using the quadrant transect method (1x1m) along 100 meters with an observation distance of every 10 meters per quadrant using 3 transect lines with a distance of 10 meters. The results found 12 species of macroalgae namely Halimeda Macroloba, Ulva intestinalis, Caulerpa Lentillifera, Neomeris Annulata, Halimeda Incrassata, Codium Arabicum, Turbinaria Ornata, Padina Minor, Acanthophora Spicifera, Amphiroa Fragillisima, Galaxaura Rugosa, and Mastophora Rosea. The diversity values of transects 1, 2, and 3 are 1.745; 1.378, and 1.294, respectively, included in the medium category. The absolute density value was highest in transect 2 (12.1), and lowest in transect 3 (7.5). The uniformity values of transects 1, 2, and 3 were 0.702; 0.555, and 0.521, respectively, including moderate (0.50 and less than 0.75). The dominance values of transects 1, 2, and 3 are 0.228; 0.348, and 0.362 respectively, which fall into the stable category or there is no dominating species. The results of physical and chemical parameters show the temperature value of 31.14°C, pH 8.99 is stable, and Dissolved Oxygen 7.62 mg/l is not polluted. In contrast, the salinity value of 35.14 ppt is not optimal, the brightness is in the low category of 0.38 m, and the turbidity value of 103 NTU is in the high category.

Abstract

Sentrum Agraris Lotta (SAL) yang terletak di Desa Lotta Jaga II, Kecamatan Pineleng, Kabupaten Minahasa, Sulawesi Utara merupakan organisasi dengan sasaran strategis sebagai percontohan pertanian organik terpadu dengan tugas utamanya sebagai wadah edukasi bagi seluruh mitra kelompok tani dengan wilayah binaan Sulawesi Utara hingga Sulawesi Tengah, selain itu SAL merupakan organisasi yang turut membantu penanganan dan mitigasi bencana. Permasalahan utama SAL yaitu permasalahan pasca panen dan permasalahan pengembangan produk pertanian menjadi produk pasca panen bernilai jual tinggi serta permasalahan diversifikasi dan peningkatan added value berbagai komoditas SAL terutama komoditas jagung yang selama ini hanya dijual dalam bentuk pipilan biji jagung sebagai bahan baku pakan ternak tanpa adanya pengolahan  lanjut yang dapat meningkatkan added value dan diversifikasi produk.  Kegiatan diseminasi dan alih teknologi pengolahan pati jagung dilakukan bersama dengan mitra sasaran SAL dengan metode sosialisasi, diseminasi dan alih teknologi pengolahan pati menggunakan teknologi tepat guna mesin penggiling dan mesin press hidrolik yang melibatkan peran aktif dari peserta dan kelompok mitra dimana produk dari kegiatan ini berupa pati jagung serta dengan adanya kegiatan ini dapat meningkatkan pengetahuan dan ketrampilan mitra dalam pengolahan pati jagung dalam upaya diversifikasi dan peningkatan nilai tambah komoditas jagung.

Abstract

Tilapia is a freshwater animal that is always in contact with the aquatic environment so that it is easily infected by bacteria through water. This study aims to identify the types of bacteria that cause diseases that attack Tilapia (Oreochromis niloticus) kept in Dimembe District, North Minahasa Regency. This study uses a descriptive exploratory research method. The results of the study found sixteen isolates and identified them as bacteria that cause Tilapia disease in North Minahasa Regency, including Aeromonas sp. (4 isolates), Plesiomonas sp. (5 isolates), and Enterobacter sp. (1 isolate). based on morphological characteristics (colonies and bacterial cells) and biochemical (catalase, oxidase and motility tests). It was found that periodic and continuous fish disease surveillance is needed to monitor the spread of fish diseases, especially Tilapia disease in North Minahasa

Abstract

This study aims to evaluate the effectiveness of the JAS (Exploration of the Surrounding Environment) approach and the STAD (Student Teams Achievement Division) type of Cooperative Learning Model in improving students' learning outcomes in biology subjects. The results of the study indicate that in Cycle I, out of a total of 15 students, 10 students had not yet met the Minimum Mastery Criteria (MMC), with a percentage of 66.67%. In Cycle II, only 2 out of 15 students had not reached the MMC, representing 13.34%, while the remaining 13 students achieved the MMC, accounting for 86.66%. These findings demonstrate an improvement in student learning outcomes following the implementation of the applied learning models. The conclusion of this study contributes to the development of more effective instructional methods to enhance student achievement and provides insights for educators in designing instruction that aligns with students' needs and interests.
