Abstract

Decreased rice productivity due to high iron concentrations especially in the vegetative phase, this causes the morphological character of rice to be affected until the metabolic process is disrupted. This study used 6 varieties, namely Batu Tegi, Inpara 9, Situ Patenggang, Inpara 8, Hawarabunar and Inpago 8, with iron concentrations of 0 and 250 ppm. The seeds were germinated for 3 days, then planted in Kimura B 10% nutrient culture media for 9 days, for 2 weeks then each week the media was changed to 100% Kimura B solution with the addition of 250 ppm iron concentration which was sampled every week until the 35th day. The results of the analysis of variance of the variables of plant height and root length showed that the combination Inpara 8-01 was the best combination and had a significant effect compared to other combinations with an average value of 61.31 cm and 30.77 cm. In the variable number of leaves the best average value was found in the combination of Batu Tegi-01 and Inpara 9-01 which had a significant effect compared to other treatments with an average value of 5.87 strands and 9.60 strands, respectively. On the stem dry weight variable, the combination of Hawarabunar-250 ppm Fe had a significant effect on other treatment combinations with the highest value of 0.17 g and the lowest value of treatment combination Inpara 9-250 ppm with a value of 0.08 g. Based on the results of treatment with 250 ppm Fe stress on plant morphological characters, the Hawarabunar variety had the best response in tolerating Fe stress, while the Batu Tegi variety was the lowest in tolerating Fe stress.

Abstract

In a construction activity, there are several aspects that require proper management and processingrequired to have accuracy, determination, performance, accuracy, and safety to produce the appropriate endwith expectations. In a project, it is necessary to handle good scheduling management. Because ofTherefore, it needs to be handled with careful and thorough calculations so that no mistakes occur when the project is in progressjust lasts. The duration of a project does not have to add up the total time of the activity,but enough to find the critical path. Scheduling a project is an outcome factor that canprovide information about the schedule plan and progress of the project. In this case, the resource performance iscosts, personnel, equipment and materials, and project duration planning. When working on a project,problems often arise, namely the project implementation time does not match the agreed time. MatterThis will have a negative impact on the company. As a result, when a project is not well planned,Project implementation involves each other throughout a series of activities that will influence each other.

Abstract

Background: Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) is one of the major global health issues, with prevalence rates that indicate a decline in several countries, including Indonesia. The number of cases of HIV/AIDS in the Province of Sumatera Selatan is quite high from 2021 to 2023. Objective: The purpose of this study is to describe the HIV/AIDS distribution pattern in the Province of Sumatera Selatan, analyze the primary contributing factors, and assess the effectiveness of the countermeasures efforts that have been carried out by the relevant parties. Method: This study uses a quantitative deskriptif approach with secondary data analysis derived from the Profile Kesehatan Provinsi Sumatera Selatan document. The variables under analysis include the number of cases of HIV/AIDS, the distribution of cases according to the type of case, and the number of affected individuals. Results: The analysis's findings indicate that the number of HIV cases has significantly increased, rising from 321 cases in 2021 to 846 cases in 2023. Proportion of sufferers was dominated by man, accounting for 82% of all cases of HIV and 83% of all cases of AIDS. The age group of 20–29 years old has the highest number of HIV-related cases, while the age group of 30–39 years old has the highest number of AIDS-related cases. Conclusion: This highlights the need for health education, access to health services, and stigma reduction for HIV/AIDS patients. It is anticipated that the results of this study will serve as a guide for the local government in determining more appropriate and effective measures to combat HIV/AIDS in the Province of Sumatera Selatan. Keywords: HIV/AIDS,Sumatera Selatan, cases distribution, public health, and countermeasures strategy
