Abstract

The environment is an important unit in the life of living creatures. The environment provides resources that are beneficial for life such as water, soil, air, minerals, flora, and fauna. Environmental pollution is a problem that often occurs and will impact the survival of living things. The aim of writing this article is to provide information on PCR technology in the living environment. Data collection was carried out by searching literature in the form of international articles for the last five years from 2018-2023 and produced 36 research articles related to PCR applications in the environment. Data searches were carried out via search engines, namely Google, PubMed, NCBI, and Publish or Perish 8 software. Based on the article, the PCR method can be used to detect microorganisms that are markers of environmental pollution.

Abstract

Hotong flour (Setaria italica) can be used as a functional food as therapy in the treatment of diabetes mellitus by reduce cholesterol levels in the blood. Hotong is a rice-like food crop that is usually consumed by the people of Buru Island. Hotong seeds have quite high nutritional content, namely containing 11.18% protein, 2.36% fat, 73.36% carbohydrates, 11.78% water, and 1.32% ash. The energy produced per 100 grams of hotong seeds is 359 calories. Hotong plants can be used as an alternative commodity in a carbohydrate-producing food diversification program. This study aims to determine the potential dose of hotong flour in treating diabetes mellitus by reducing cholesterol levels in the blood of rat. This research used 24 wistar rats animals which were divided into 6 groups which were given hotong flour for 21 days and the cholesterol levels were evaluated on the 7th, 14th, and 21st day. Determination of rat blood cholesterol levels using the enzymatic method. Hotong flour can reduce blood sugar levels at doses of 1 g/kg bw and 1.5 g/kg bw in rat that have been made diabetic by examination on days 7, 14 and 21 days.

Abstract

The purpose of the research was to investigate the knowledge breeders of the native chicken in Nusalaut island in relation to good native chicken production practices. Both villages and respondents were selected used purposive sampling method. The variables were knowledge of the farmers, sex, age, education, household dependency rate, length of experience and the level of income from main job. The results showed that majority (72 %) respondents attained primary school, average dependency rate 4.9 ± 1.75 persons, majority (70 %) low income, more men possessed high knowledge than women (p = 0.047), length of experience affect knowledge significantly (p=0.184) and education affect knowledge highly significantly. It was concluded that although native chicken breeders have good knowledge about chicken production in overall, but there are certain knowledge gaps on feeding and controlling diseases.

Abstract

Group investigation is a learning model focused on collaboration between teachers and students, involving task sharing, sub-theme assignments, and presentation schedules. Inquiry learning emphasizes critical and analytical thinking to solve problems or answer questions, and it can involve the use of miniature models to enhance cognitive and metacognitive skills. The aim of this study is to determine how the integration of the Group Investigation Learning Model and Inquiry Learning Strategy impacts cognitive and metacognitive learning outcomes in students at the Fourth Public Senior High School of Ambon, Maluku Province. The methods used in this research are descriptive statistics and inferential statistics. Based on the cognitive learning results of analysis covariance, the significant value is 0.001, which is less than the critical value of 0.05. This means that the research hypothesis is accepted, indicating that there is an influence of the Group Investigation model and Inquiry Strategy on the improvement of learning outcomes for students in the Eleventh Grade Natural Sciences Interest Group. Additionally, the metacognitive learning result has a significant value of 0.006, which is less than critical value, meaning that the hypotheses are accepted, indicating that Group Investigation and learning strategies have a positive influence on improving students' metacognitive learning outcomes.

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 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.
