Abstract

Candida albicans is a dimorphic fungus that can grow in culture as a blastopore or as pseudohyphae. Laboratory diagnosis of the Candida albincans fungus can be carried out molecularly, which aims to identify DNA in the fungus being examined and carried out by going through the initial molecular stage, namely DNA isolation. The purpose of this study was to determine whether the fungus Candida albicans was present in urine isolate samples from diabetes mellitus sufferers at the Wonosari 1 Klaten Community Health Center. The research method used is descriptive. The samples used were urine samples from diabetes mellitus sufferers at the Wonosari 1 Community Health Center. Based on the research results, data analysis and discussion in this study, it can be concluded that the Candida albicans fungus can be detected in the ITS2 region at a product length of 107bp using the Polymerase Chain Reaction (PCR) method.

Abstract

Free radicals need to be handled and even prevented so that they are not exposed to the skin, especially the hands. One solution to preventing the exposure of free radicals to the skin of the hands is to wash your hands with herbal soap which is made from the active ingredient of telang flower kombucha. Telang flower kombucha was designed as an active ingredient in the formulation and hand washing soap preparation in this research has been proven as a pharmaceutical biotechnology product in warding off free radicals. This research was designed by making a formulation and preparation of telang flower kombucha hand washing soap at concentrations of 20%, 30% and 40% then measuring it using UV-Vis spectrophotometry. Based on statistical analysis, especially post hoc analysis of pharmaceutical biotechnology products in the form of formulations and preparations of telang flower kombucha hand washing soap at a concentration of 40%, it is significantly different from 20% and 30% as a source of antioxidants.

Abstract

Biochar is recognized as a versatile and sustainable tool for improving agricultural and environmental conditions due to its unique physicochemical properties, such as soil fertility, nutrient retention and water holding capacity. The presence of biochar, which contains stabilized carbon, not only has a positive impact on plant growth and crop yields through microbial activity, but can also act as a sorbent to remove contaminants from soil and water. However, the use of biochar in soil and its effects on ecosystem services depend on several factors. This article explores the impact of biochar use on soil and the potential to address ecosystem service challenges by improving soil composition, increasing access to water, and removing contaminants, all to promote sustainable agriculture. The method of this article consists of a literature review by collecting data from various sources such as scientific journals, books and seminar proceedings. The data obtained were qualitatively analyzed to review and identify the information, resulting in a critical and comprehensive explanation and discussion of the role of biochar in improving soil and environmental quality for environmental services. The results of the literature review are presented in the form of a coherent, systematic and critical narrative. The results of this article review indicate that on-farm biochar application contributes significantly to climate change mitigation through various mechanisms, including biochar's ability to sequester carbon, improve soil quality, and minimize greenhouse gas emissions.

Abstract

An invertebrate critter called Saccostrea cucullata is typically found adhering to substrates like rocks and mangrove roots. The purpose of this study is to ascertain S. cucullata's abundance and distribution patterns. This study was carried out at West Lombok's Bagek Kembar Sekotong Natural Mangrove Area in February 2024. The samples were observed using the 5 x 5 m quadratic transect approach. To ascertain S. cucullata abundance and dispersion patterns, descriptive analysis was performed on the data. According to the study's findings, station I had the greatest abundance (1.81 Ind/m2), while station III had the lowest (0.95 Ind/m2). S. cucullata exhibits a clustered and uniform distribution pattern in certain areas. In the research region, temperature, salinity, and pH are the main factors affecting S. cucullata abundance and dispersion pattern, respectively.

Abstract

Rice plays an important role in meeting carbohydrate requirement and calorie needs to ensure food security. However, in recent years, rice productivity has decreased due to land conversion and climate change such as El Niño. The productivity of drought-resistant rice can be increased through breeding. Genetic diversity and heritability are important genetic parameters in the plant breeding process. Information about genetic diversity and heritability helps determine genetic progress through selection. This research aims to examine the potential genetic diversity and heritability of several mutant lines (M4) of black rice (G10) in order to develop superior rice varieties that are adaptive to dry land. In this research, we used experimental methods using a Randomized Block Design (RBD), calculating the value of the Genetic Diversity Coefficient (GDC) and heritability between quantitative characters. The results of narrow genetic research were found in the characteristics of the number of productive tillers and weight of 100 grains, while high heritability was found in the characters of plant height, moderate heritability was found in the total number of tillers, panicle length, number of empty grains per panicle, and weight of 100 grains. Overall, this research succeeded in identifying mutant lines (M4) of black rice (G10) which have the potential to be developed into superior varieties, especially for cultivation in dry land.

Abstract

There is an increasing rate of land conversion in Indonesia that can threaten food self-sufficiency. Therefore farmers and the government must expand agriculture by developing agriculture on potential available lands such as drylands. However, drylands in Indonesia have low productivity due to low water and nutrient availability. This article aims to determine the potential use of arbuscular mycorrhizal fungi to overcome drought stress and low nutrient availability in drylands. The method used in writing this article is a desk literature study conducted by collecting data from various sources, such as scientific journals, seminar proceedings, and online reports available in related government office in West Nusatenggara Province. The data obtained were then analyzed qualitatively by identifying, reviewing, and synthesizing information to produce a complete and comprehensive explanation. The results of the literature study showed that arbuscular mycorrhizal fungi have the potential to overcome drought stress and low nutrient availability in drylands. The use of arbuscular mycorrhizal fungi can be a sustainable solution to increase agricultural productivity in drylands.

Abstract

The whitefly is a pest that frequently infests cultivated plants, causing both direct and indirect damage that can significantly reduce crop yields. In addition to whitefly infestations, declining soil fertility is another factor that can lead to decreased production. One potential solution to these issues is the use of UV plastic shade. This method can help reduce the population of whitefly pests. This article aims to explore the effectiveness of UV plastic shade in enhancing soil fertility and reducing whitefly presence in arid regions. The research methodology employed is descriptive, utilizing a literature review of sources such as scientific articles, books, journals, discussions, and previous research findings. UV plastic shade has been found to increase the availability of nitrogen and phosphorus in the soil, thereby promoting soil fertility and plant growth. Additionally, UV plastic shade can reduce whitefly populations in dry areas by disrupting their life cycle and behavior.
