A Review of Fungal-Derived Natural Dyes: Chemical Diversity and Multifaceted Health Benefits
Get PDFVarious industrial sectors, from food and drug production to textiles, have widely used pigments or dyes as coloring agents. Generally, we can distinguish between two types of coloring agents: synthetic and natural. Currently, the use of synthetic colorings is a topic of debate due to their potential health risks, toxicity, and environmental pollution. This prompts a deeper exploration of natural resources as a more secure substitute for coloring agents. Plants, animals, microbes, and fungi can all provide natural coloring agents. Besides animals and microbes, some challenges in developing plants as major sources of natural coloring agents include variations in production or harvest times, strongly influenced by season, weather, and the intensity of sunlight. These factors influence not only the stability of the produced color but also its physicochemical properties, such as solubility and pH. Moreover, overexploitation of plants has an impact on ecosystem imbalances and leads to extinction. Among natural resources, pigments or dyes from fungi have shown their potential to address these challenges. This review focuses on the potential of various microfungi that produce natural dyes, especially from Monascaceae, Trichocomaceae, and Nectriaceae, as well as the classification based on their chemical structure. Furthermore, we describe their diverse biological impacts as antioxidants, antibiotics, antidiabetics, anticancer agents, and anti-cholesterol agents, along with their health advantages
The Potential of Self-Organised Learning Environment E-Module to Enhance Students\u27 Critical Thinking Skills and Cognitive Learning Outcomes
Get PDFThe objective of this study was to ascertain the impact of critical thinking skills on the learning outcomes of junior high school students, with the Self- Organized Learning Environment (SOLE) learning model serving as the experimental framework. The research methodology employed was quasi- experimental, with a research design of nonequivalent control group design. In this study, the experimental class was Grade 8 A Class, while the control class was Grade 8 C class. The SOLE learning model demonstrated a statistically significant effect on critical thinking skills and learning outcomes, as evidenced by the t-test results with a value of 0.05 < 0.000. The N-gain score for the SOLE learning model revealed that 51.5% of the learning outcomes were less effective, while 56.8% of the critical thinking skills were moderately effective. In contrast, the control class in the Discovery Learning learning model achieved 32.3% in learning outcomes and 38.2% in critical thinking skills, both of which were ineffective. The results of the research indicate that critical thinking skills and junior high school science learning outcomes are significantly influenced by the SOLE learning model
Analisis Faktor-Faktor yang Mempengaruhi Indeks Pembangunan Manusia (IPM) Di 9 Kabupaten/Kota Di Provinsi Bali Tahun 2018-2021
Get PDFIPM (Indeks Pembangunan Manusia) penting dalam melihat level capaian pembangunan manusia di suatu kawasan atau negara. IPM memegang peranan penting dalam pertumbuhan ekonomi suatu kawasan atau negara. Negara-negara berkembang seperti Indonesia belum sukses dalam mengatasi permasalahan ekonomi karena faktor kesenjangan sosial. Diantara kesenjangan sosial, persoalan yang biasanya dihadapi oleh negara berkembang adalah persoalan pembangunan manusia. Pembangunan manusia yang baik akan membantu suatu negara meningkatkan kualitas hidupnya dalam berbagai aspek kehidupan. Tujuan dari penelitian ini yaitu untuk menentukan hal-hal yang mempengaruhi IPM di provinsi Bali. Salah satu provinsi di Indonesia yang paling dicari wisatawan adalah Bali. Salah satu variabel independen yang digunakan pada penelitian ini yaitu investasi. Biasanya diambil hanya dari salah satu indikator pertumbuhan modal asing atau dalam negeri, dalam penelitian ini digunakan data dari total penanaman modal asing dan modal dalam negeri. Analisis data panel digunakan dalam penelitian ini, yang menggabungkan data cross section dengan time series. Bertujuan untuk menganalisis pengaruh upah minimum kabupaten/kota, investasi, PDRB per kapita, dan jumlah penduduk miskin terhadap IPM. Hasil penelitian menunjukkan investasi dan PDRB per kapita berpengaruh pada IPM. Variabel seperti upah minimum kabupaten/kota dan jumlah penduduk miskin tidak berpengaruh terhadap IPM. Variabel investasi dan PDRB per kapita mempunyai pengaruh positif terhadap IPM yang menunjukkan bahwa semakin besar variabel tersebut maka IPM juga akan meningkat
