Background: Evaluation of the tolerance level of rice to iron (Fe) toxicity stress can be done using a hydroponic system in a nutrient culture solution under a controlled condition. This study aimed to obtain a nutrient culture solution that effective as a medium for evaluating the response of rice under Fe toxicity stress condition. Methods: This experiment was carried out by comparing the effectiveness of three kinds of nutrient culture media, namely Yoshida’s Half-Strength solution (HSY), Yoshida’s Half-Strength + 0.2% agar solution (HSYA), and Yoshida’s Full-Strength + 0.2% agar solution (FSYA) using two rice genotypes, Inpara 5 (sensitive to Fe toxicity) and Mahsuri (tolerant to Fe toxicity). Leaf bronzing level, plant dry weight, and pH of nutrient culture media were observed in this experiment. Results: The results showed that the stress response as represented by the bronzing score in Inpara 5 leaves was known to be higher than that of Mahsuri in the three nutrient culture media. The decrease of root and shoot dry weight in Inpara 5 was higher than that of Mahsuri. In addition, the decrease in the pH of nutrient culture solution media without an agar addition (HSY) occurred faster than the media with the agar addition (HSYA and FSYA). Conclusion: The HSYA and FSYA media exhibited a similar pattern of pH declining but causing significant differences in growth responses between Inpara 5 and Mashuri indicating the HSYA medium is considered more efficient compared to the FSYA medium because it only requires a smaller amount of agar.

Background: Assessment is a crucial step for determining whether or not a learning process has been successful. High-order thinking skills are a requirement for learning achievement in the twenty-first century. The goal of this project is to put quantitative evaluation instruments created by Jakarta elementary school teachers to the test. Methods: A mix method is used, which combines descriptive qualitative research with document analysis and quantitative research with instrument testing on reproductive system material, which is then examined using Anates. The participants in this study were eight Jakarta-based grade VI primary school teachers. Results: It demonstrates that teachers' capacity to construct evaluation instruments varies widely. Testing using Anates shows 15% of the questions compiled are valid and 85% invalid, 1 school with strong reliability and 7 other schools are less reliable. The difference shows that 42.5% are accepted and 57.5% are rejected. The level of difficulty showed that as many as 8.75% of the questions were in the very easy category, 18.75% easy, 51.25% moderate, 7.5% difficult and 13.75 very difficult. These results form the basis of the importance of the hierarchy of teacher understanding in depth, especially in relation to the preparation of HOTS-based assessment instruments because the quality of learning success is largely determined by the assessment instrument used. Conclusions: The LOTS and HOTS-based capability instruments made by the teacher at 8 East Dijakarta Elementary Schools have not been maximized and need development by these teachers.

Background: Breadfruit [Artocarpus altilis (Parkinson ex F.A.Zorn) Fosberg] is a versatile plant that can be used by humans. Breadfruit has morphological variations that are thought to be related to anatomical variations that are formed as an adaptation mechanism to survive in a different area. This plant has the ability to live in different altitude ranges, from coastal areas to upland areas. This research was conducted for eight months in areas with altitude ranges of <350 masl, 350-700 masl, and >700 masl in Banyumas, Purbalingga, and Cilacap Regencies. Sampling of plants was carried out randomly selected (purposive random sampling), then described their morphological characteristics. Furthermore, the leaves are made for anatomical preservation to determine the anatomical character. Breadfruit plants that grow at an altitude of less than 350 m above sea level have the characteristics of a higher, larger diameter stem, have a tighter branching, more sap production, a higher number of fruit and have a larger fruit size. The anatomical characteristics of breadfruit plants that grow at an altitude of less than 350 masl have stomata characters that are wider and longer than those of 350-700 masl and > 700 masl. The highest stomata and trichomata density at an altitude > 700 masl. The highest mean cuticle thickness, epidermis, palisade ratio and mesophyll thickness were highest in breadfruit leaves at altitudes <350 masl.

Background: Entomopathogenic fungi are one of the potential biodiversity assets to be used as biological control agents. However, information about the diversity of entomopathogenic fungi, especially in the Gunung Tukung Gede (GTG) nature reserve is very limited. The purpose of this study was to provide information on the biodiversity of entomopathogenic fungi in the GTG nature reserve. Methods: The entomopathogenic fungi were explored from 3 different stations: primary forest, secondary forest and disturbed forest. Entomopathogenic fungi were isolated identified both macroscopically and microscopically. Results: A total of 15 specimens of entomopathogenic fungi consisting of 5 families and 8 types of fungi successfully isolate. The entomopathogen fungi were Basidiobolus haptosporus, Beauveria bassiana., Metarhizium aniesophalie, Paecilomyces sp., Aschersonia sp., Aspergillus sp. 1, Aspergillus sp.2, and Septobasidium sp. These fungi infect insect hosts from the orders Lepidoptera, Hemiptera and Homoptera. The index of the diversity of entomopathogenic fungi at 3 consecutive stations is 1.5495; 1.3322; and 0.6365 (medium category). Conclusions: The GTG Nature Reserve has a unique diversity of entomopathogenic fungi. Therefore, further research is needed in order to determine the diversity and potential utilization of the existing entomopathogenic fungi.

Background: Melanoma is a skin disorder caused by malignant degeneration of the pigment cells melanocytes. The disease is characterized by widespread discoloration with irregular and protruding edges. In treating cancer itself, radiotherapy technology, has been found. It is a method of treating cancer using high-energy radiation rays that are focused on cancerous tissue to kill or stop cancer cell division. This study aims to determine the effectiveness of radiotherapy technology as a treatment solution for melanoma skin cancer. The focuses of the study in this paper are the integumentary system and skin structure, melanoma skin cancer, the body's mechanisms for melanoma skin cancer, and radiotherapy as a treatment method. Methods: The research method used is literature study from various sources, to help understand the problem more deeply and completely. Conclusions: Melanoma, which attacks one of the body's integumentary systems, namely the skin, has a close relationship with homeostatic dysregulation and endocrine damage. However, radiotherapy method can be used to cure melanoma skin cancer by shooting X-rays and damaging the cancer cells and also reducing their spread to other parts of the organs. This method is effective because melanoma skin cancer is localized or has not spread to other organs. However, the use of radiotherapy can also have a negative impact on the body and can give unwanted side effects, so consideration is needed before using this method.
