Candidiasis is an acute and subacute fungal infection caused by the Candida group, especially Candida albicans. Infectious diseases due to microbes can be treated using modern drugs, namely antifungals. In some cases, antimicrobials often develop resistance due to improper administration. The occurrence of such resistance encourages further research on new active ingredients that can be used as antimicrobial alternatives, especially from plant sources containing flavonoids. The purpose of this study is to determine the effect of antimicrobial content of ethanol extract 70% of Telang flowers on the growth of C. albicans. This research is a laboratory experimental research with post test control group design only method. Determination of antimicrobial activity is carried out by the pitting method. Telang flower extract that has been diluted with 10% DMSO, taken as much as 30µl then dripped into the well. Positive control using antimicrobial ketocenazole and negative control using DMSO 10% which was dripped on the well as much as 30µl. Based on the results of observations, the inhibition zone is only formed in positive control with an average of 15.5 + 0.4 mm. The results of ethanol extract of 70% Telang flowers that have been conducted did not show antimicrobial activity against fungal growth C. albicans. The absence of this inhibitory zone is due to the unknown concentration of active compounds of Telang flowers that are responsible as antimicrobials, so it is necessary to conduct research on the search for concentrations of active compounds that have the ability as antimicrobials.

CV XYZ is a company engaged in the production of fashion. The problem that occurs in CV XYZ is that there are still several cases of work accidents caused by the attitude of workers, the work environment and the tools used during the production process. The purpose of this study is to analyze the potential hazards and the causes of potential hazards, the risk of injury and even work accidents and provide suggestions for improvements to reduce the risk of work accidents so that control and prevention of hazards that arise in the work area can be carried out. The methods used in this research are Hazard and Operability Study (HAZOP) and Job Safety Analysis (JSA). Hazard and Operability Study (HAZOP) is a hazard identification approach in working environment conditions, existing facilities, equipment operation and overall production. Hazop looks for possible causes of accidents and determines the consequences of deviations that occur when a job is done. Job Safety Analysis (JSA) is the identification of hazards by taking into account unsafe act and unsafe conditions. This hazard identification method is carried out by studying a job to identify hazards and potential incidents associated with each step and used to find solutions and control existing hazards. Based on the results of data processing, it is known that the sources of hazards that exist or have the potential for work accidents are the attitudes of workers and the physical work environment and it is known that there are 30 identified hazards from 16 routine activities and 7 of them have the highest risk of intensity in causing hazards in the work area.

The era of digitalization has brought improvement and progress in various facets of public life, particularly in the aspect of public governance sustainability. However, as a social phenomenon, digitization in the governance process is inseparable from the population and civil registry conflicts which are intertwined. As a narrow practical example, the implementation of Validasi Data Kependudukan Apps in the Nanggerang Village of Sumedang Regency represents the empirical occurrence that digitalization represented by the Apps in the realm of public governance does not operate as expected, on the other hand, population and civil registry conflicts arise over the presence of the application implementation and its policies. This study aims to examine the application of “Validasi Data Kependudukan” in Nanggerang Village, Sumedang Regency as a social phenomenon representing sustainable public governance. A qualitative descriptive method with interview and empirical observation are conducted as analytical tool. In a conclusion, this study reveals that the existence of a Validasi Data Kependudukan Apps is the impact of the digitalization process in the government and is a derivative of the application that has been implemented in Sumedang Regency. Throughout the implementation process, there are problems with public awareness related to the existence of this application, causing conflicts between the government and the community itself in terms of managing population documents. Accommodation is an obstacle to existing awareness problems and has an impact on the ideals of sustainable public governance.
数字化时代带来了公共生活各个方面的改善和进步，特别是在公共治理可持续性方面。然而，数字化作为一种社会现象，在治理过程中离不开人口与民事登记冲突的交织。作为一个狭隘的实际例子，Validasi Data Kependukan应用程序在苏梅当县Nanggerang村的实施代表了一种经验，即应用程序在公共治理领域所代表的数字化并没有如预期那样运行。另一方面，人口和民事登记处因应用程序实施及其政策的存在而发生冲突。本研究旨在检验“Validasi Data Kependukan”作为一种代表可持续公共治理的社会现象在苏梅当县南格朗村的应用。采用访谈和实证观察相结合的定性描述方法作为分析工具。总之，本研究表明，Validasi Data Kependukan应用程序的存在是政府数字化进程的影响，是苏梅当县实施的应用程序的衍生产品。在整个实施过程中，公众对该应用程序的存在的认识存在问题，导致政府和社区本身在管理人口文件方面发生冲突。通融是现有认识问题的障碍，并对可持续公共治理的理想产生影响。

The sample in this study was a science teacher at SMP DR Wahidin Sudirohusodo Medan, who were selected using a purposive sampling technique and developed using a snowball sampling technique. Data collection was carried out through interviews and questionnaires. Data analysis techniques were carried out in an interactive descriptive manner. The results of this study indicate that the teacher's perception is positive because they welcome the implementation of the independent learning curriculum, supported by adequate socialization and training so that they can apply the concept of learning science in accordance with the independent learning curriculum. Constraints experienced by teachers in the form of technical and non-technical constraints. There are several factors that become obstacles, namely, the first is the inadequate quality of the teacher's human resources, the second is that the facilities and learning resources are minimal or the infrastructure is inadequate and the teacher is clueless, the third teacher is comfortable with the old standard and has no experience in learning independent study.
本研究旨在：描述教师对科学教育中独立学习课程实施的看法，描述教师在实施独立学习课程时感受到的制约因素以及克服这些障碍的解决方案。这类研究是一个案例研究。本研究中的样本是SMP DR Wahidin Sudirohusodo Medan的一名科学教师，他们是使用有目的的采样技术选择的，并使用滚雪球采样技术开发的。数据收集是通过访谈和问卷调查进行的。数据分析技术是以互动描述性的方式进行的。这项研究的结果表明，教师的看法是积极的，因为他们欢迎实施独立学习课程，并辅以充分的社会化和培训，以便他们能够根据独立学习课程应用学习科学的概念。教师所经历的技术和非技术约束形式的约束。有几个因素成为障碍，即，第一是教师的人力资源质量不足，第二是设施和学习资源最少或基础设施不足，教师一无所知，第三是教师适应旧标准，没有学习独立学习的经验。

Several studies from Indonesia reveal that malnutrition and stunting are still severe concerns to be addressed in the future. The complexity of the problem of stunting or nutritional status requires the responsibility of all parties, including science and technology. The issue of monitoring and data collection related to stunting or the nutritional status of children in Indonesia, especially Medan City, North Sumatra Province, is an essential factor in determining the calculations carried out by each Community Health Center with many attributes. Currently, the Support Vector Machine method is a solution to increase government intervention's effectiveness in classifying malnutrition and stunting. However, the Support Vector Machine algorithm still needs to improve, namely the difficulty of selecting the right and optimal features for the attribute weights, causing a low prediction accuracy. Therefore, researchers aim to optimize the Support Vector Machine Algorithm with Particle Swarm Optimization using Linear, Polynomial, Sigmoid, and Radial Basic Function kernels. The results were obtained from research utilizing nutritional status data, that performance in improving the Support Vector Machine algorithm based on Particle Swarm Optimization using four kernel tests, namely Linear, Polynomial, Sigmoid, and Radial Basic Function obtained different results, not all kernels in this study can improve accuracy well. The best performance is using the Radial Basic Function kernel with an Accuracy value of 78%, Precision of 89%, Recall of 66%, and F1-Score of 72%, so it is feasible for accurate information regarding the classification of nutritional status.
