Abstract

Rural landscapes are part of man-made landscapes as a result of conversion of natural landscapes due to human needs. Birds respond positively to these changes as ecosystem components that are able to adapt and survive in rural landscapes. The countryside in the northern part of the Sukabumi is located between the natural landscape of Mount Gede and the rural landscape of Sukabumi City. The research aims to analyze the diversity of bird in the rural landscape of the Sukabumi Area. Research in the form of direct observation was carried out in February-May 2022.  Bird data was taken using the point count method in the morning and evening. Qualitative analysis was carried out by describing and looking at the protection status. Quantitative analysis was carried out using (1) chi-square test, (2) Margalef Index (DMg), (3) Shannon-Wiener Index (H'), (4) venness index (E), and similarity index community (IS). There were 43 species of birds found from nine orders and 23 families. Five species birds are protected by the Indonesian Government. A total of 25 species (58%) are members of the Order Passeriformes. The majority are terrestrial birds, there is only one species that is considered a water bird, namely Von Schrenck’s Bittern (Ixobrychus eurhythmus). The DMg value obtained was 2.23-6.45, while the H' value obtained was 1.70-3.24, while the E value obtained was 0.74-09.90. The IS values obtained ranged from 0.24-0.58 with the highest similarity between the rice field habitat and the vegetable farm habitat.

Abstract

The study of ethnozoology is closely related to local culture and knowledge and their interaction with the surrounding environment. Islam was brought to Kudus by Ja'far Shadiq, known as Sunan Kudus, using a unique da'wah strategy, namely, the fatwa on the prohibition of cow slaughter for the people of Kudus. The social tradition of the community regarding the prohibition of slaughtering cattle, makes the Kudus area more likely to consume buffalo meat than beef. The purpose of this research is to find out the ethnozoological perspective related to the prohibition of cattle slaughter (Bos taurus) according to the philosophy of the teachings of Sunan Kudus in socio-cultural and economic life. The research method used is qualitative field research with qualitative description analysis techniques. Data collection was conducted through observation, literature review and interview results related to general knowledge of customary, cultural and ethnozoological aspects in depth with informants. The data were analyzed descriptively qualitatively by making transcripts of the interview results which were written carefully taking and recording important information with the research context. The research was conducted in several areas of Kudus, including Kirig Village, Ngembalrejo Village, and Dawe District. Based on the results of the research, the fatwa on the prohibition of slaughtering cows in Kudus has been believed by the community from the past until now, but the results show that there are still some Kudus people who slaughter cows, one of which is the Muhammadiyah Islamic group, besides that, the Kudus community utilizes buffaloes as a function of cows, all of which go back to their respective beliefs because there are still many cattle breeders found to be traded.

Abstract

Oxidative stress leads to numerous clinical problems, such as autoimmune, vascular and respiratory impairment, as well as many other degenerative diseases. While daily exposure to UV light, air pollution, and smoke largely contribute to oxidative stress, endogenous antioxidants mostly fail to neutralize these high amounts of free radicals. Stevia rebaudiana or “candyleaf” is largely found in Indonesia, known for its application as a natural sweetener, owing to its content of stevioside compound. This study is experimental research which aims to assess the potential of stevia extract as an antioxidant supplement, which has not been widely applied. In vitro study was performed by extracting stevia leaves in methanol through simple maceration and percolation methods. Subsequently, the stevia extract was subjected to biochemical analysis, i.e. phytochemical screening, total phenolic content assay, antioxidant capacity assay, and toxicity assay. Herein, we found that stevia extract contains flavonoid, saponin, tannin, terpenoid, and phenolic compounds, with total phenolic content of 86.30±1.14 mg GAE/g DW. Moreover, antioxidant capacity assay through 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) method showed that IC50 of stevia extract is 20.13 µg/mL, slightly higher than Trolox (vitamin E analog) with IC50 of 16.50 µg/mL, which indicated that stevia extract is a very strong antioxidant. As for toxicity bioassay, Brine Shrimp Lethality Test indicated that stevia extract is non-toxic with LC50 value of 3388.44 µg/mL.

Abstract

This study aims to validate concept understanding instruments on cell material for high school students using Content Validity Ratio (CVR) and Content Validity Index (CVI). Instrument validation was conducted by five experts from three different universities. The results showed that most of the items had CVR and CVI values that met the established validity criteria, only a few items were declared invalid and needed to be revised or deleted. Furthermore, the results of the reliability test using Cronbach's Alpha obtained a value of 0.913 which indicates that this instrument has excellent reliability. This valid and reliable instrument can be used by biology teachers in high school to measure students' concept understanding of cell material. The use of this instrument is expected to help identify weak areas of student understanding and design more effective learning strategies. This research supports the importance of instrument validation to ensure the accuracy of measurement results and increase teacher and student confidence in the results obtained. Thus, the instrument that has been developed is expected to contribute significantly to improving the quality of biology learning in high school.

Abstract

The use of synthetic pesticides is not effective in reducing the prevalence of disease because it produces residues and does not support biodiversity. This is an unwise practice and can cause problems in the future.  The use of endophytic microorganisms is widely used to control plant diseases and pests, because it is known to have various pathogen inhibition mechanisms. Biological agents that are used to inhibit plant pathogens and have been widely developed, one of which is endophytic bacteria. The purpose of the research was to evaluate the potential of endophytic bacterial isolate from ginger plants as biological control agents. The type of research used is descriptive and exploratory. Sampling of healthy ginger plants was carried out at 5 points in two sub-districts, namely Getasan and Sumowono, Semarang Regency. Isolation is carried out by taking healthy ginger plants from the roots, rhizomes, fronds, and leaves. Characterization and selection of isolates were carried out by testing their phosphate dissolving ability, nitrogen anchoring, amylase and protease activities, and antagonist tests with Fusarium oxysporum in vitro. The results of this study are that (1) 20 pure isolates were successfully isolated consisting of 2 isolates derived from leaves, 4 isolates from fronds, 8 isolates from roots, and 6 isolates from rhizomes; (2) D91 isolate has the potential as a biological agent with an antagonist mechanism of 86.91% supported by protease enzyme activity, able to dissolve phosphate and anchor nitrogen.

Abstract

The objective of this study is to determine the primary factors that contribute to the mortality rate of COVID-19 in Indonesia, with a specific focus on age, comorbidities, and vaccination status. A retrospective analysis was performed utilizing patient data obtained from the West Lombok Health Office in the year 2020. The findings indicated that individuals aged 59 years or older had a considerably higher risk of mortality, with an odds ratio of 0.065 (95% confidence interval: 0.014 - 0.305). Comorbidities, specifically hypertension and diabetes mellitus, were found to be substantial risk factors. The odds ratio for hypertension was 63.64 (95% CI: 1.232 - 30.608), while the odds ratio for diabetes mellitus was 2.00 (95% CI: 1.593 - 2.512). The study revealed that being vaccinated considerably decreased the likelihood of death, with an odds ratio of 0.071 (95% CI: 0.015 - 0.334). Nevertheless, engaging in self-isolation was found to greatly elevate the likelihood of mortality, as indicated by an odds ratio of 195.429 (95% confidence interval: 22.894 - 1668.196). The Chi-Square test revealed a statistically significant association between vaccination status and COVID-19 mortality, with a p-value of 0.000 < 0.05. The logistic regression analysis revealed that the type of isolation had a very significant and large effect on COVID-19 mortality. The odds ratio (Exp(B)) was 96.604, showing a strong association between the type of isolation and the mortality rate. The p-value was 0.000, further confirming the statistical significance of this relationship. Therefore, the type of isolation plays a critical role in determining the death rate of COVID-19 patients. These findings emphasize the significance of immunization programs and efficient isolation measures in decreasing COVID-19 mortality. In summary, this study offers significant information that can be used to develop more focused health policies in Indonesia. It emphasizes the crucial importance of vaccination and isolation measures in effectively managing the COVID-19 pandemic. Gaining insight into these factors can assist in customizing health treatments to mitigate risks and enhance clinical outcomes for COVID-19 patients in Indonesia
