This study was motivated by the phenomenon of increasing anti-feminism and digital misogyny in Germany, where constitutionally guaranteed equality has suffered a practical setback in the form of a decline in female representation in the Bundestag to 32,4%. This situation has triggered an urgent need for persuasive communication through state addresses. This study aims to analyze the emotional rhetoric (pathos) and intonation strategies in the Ansprache zum Welt-Frauentag in order to raise audience awareness. The method used is a mixed method of qualitative analysis of rhetoric by Aristoteles (2007) and quantitative digital acoustic analysis using Praat software supported theory by Kohler (1995). The data for this analysis are transcripts and audio recordings of the Ansprache zum Welt-Frauentag delivered by Bundespräsident Steinmeier. The results of the study identified three typologies of relationships between diction and intonation, namely contradiction, in which emotional diction is delivered in a flat tone to maintain objectivity; compensation, in which neutral legal references are given emotional weight through a rise in tone (late peak); and parallelism, which is the harmony between emotional diction and the highest voice frequency to build strong authority. Thus, this study confirms that the effectiveness of persuasion in a speech does not only depend on the text, but also on the flexibility of manipulating voice frequency, which strategically functions as an instrument for navigating the audience’s emotions.

Until now, truancy behavior is still frequently found among students during school hours. This behavior is caused by various factors, such as waking up late, staying up too late at night, feeling tired or sleepy, vehicle problems such as flat tires, lack of motivation to go to school, and other reasons. This problem has become an important concern for school counselors in providing assistance, one of which is through individual counseling services. Students’ participation in the learning process greatly affects the smoothness of learning and the results achieved at school. If truancy behavior continues to be ignored, it can lead to more serious impacts and even increase the risk of students dropping out of school. Therefore, school counselors have an important role in helping overcome this problem with support from students, subject teachers, and parents. One method that can be applied is individual counseling using the behavior contract technique. This technique aims to help students change negative behavior into more disciplined behavior so that truancy habits can be reduced and not repeated again. This study used a qualitative method with interview techniques for data collection. The results of the study showed that individual counseling services using the behavior contract technique were effective in helping overcome truancy behavior among students.

This study aims to analyse the difficulties experienced by students in learning about flat-sided three-dimensional shapes. The research method employed is descriptive with a qualitative approach. The data collected in this study were obtained from students’ difficulty tests and interview results. The research subjects were Year 8 pupils at SMP Negeri 2 Ponelo Kepulauan in the 2024/2025 academic year. The interviews were conducted by selecting three questions related to difficulties in learning mathematics, with one student chosen as a respondent to be interviewed on 26 August 2025. The indicators used to assess students’ learning difficulties were: facts, principles, concepts, and operations.

Disc discs are the main component in a motorcycle braking system that functions to convert kinetic energy into heat energy through friction. The geometric design of the disc, including the diameter and number of holes, affects the effectiveness of braking as well as the heat dissipation ability. This study aims to analyze the effect of variations in diameter and number of holes on disc discs on braking distance and disc temperature. The research method used was an experimental method with three variations in disc diameter (190 mm, 220 mm, and 260 mm) and three variations in the number of holes (30, 36, and 42 holes). The test was carried out through a controlled braking procedure at an initial speed of 40 km/h on flat road surfaces with stable weather conditions. Braking distance data is measured using ultrasonic sensors, while disc temperature is recorded with a high-accuracy infrared thermometer. The results showed that the diameter of the disc disc had the most significant influence on the braking distance. The larger the diameter, the greater the braking moment resulting so that the stopping distance becomes shorter. The number of holes in the disc also plays a role in heat dissipation because the holes enlarge the heat dissipation area. However, the increase in the number of holes tends to slightly increase the braking distance due to a reduction in the area of frictional contact field. The most optimal configuration is found on a 260 mm diameter disc with 42 holes, which results in the shortest braking distance of 8.25 meters and the lowest temperature rise of 4.47°C.  Statistical analysis using Two-Way ANOVA confirmed that the diameter and number of holes had a significant effect individually, but there was no significant interaction between the two. These findings confirm that the selection of the right disc dimensions is critical to improving braking performance, thermal efficiency, and rider safety.

This study was conducted to isolate and identify lactic acid bacteria (LAB) present in nilem fish bekasam, a traditional fermented product from Muaro Jambi. A 1-gram sample of bekasam, which had been fermented for 7 days, was used as the test material. The sample was diluted in stages to 10⁻⁶ and then plated on Nutrient Agar medium using the pour plate method. The incubation was carried out at 37°C for 24-48 hours. Upon observation, bacterial colonies with characteristics typical of lactic acid bacteria were noted. These colonies were small in size, round in shape, white to cream in color, had smooth surfaces, and flat edges. Gram staining tests revealed that most isolates were Gram-positive bacteria with rod or oval shapes, which is consistent with the characteristics of the Lactobacillus genus. Further tests showed that these bacteria were catalase-negative, non-spore-forming, and produced lactic acid as their primary metabolic product. These findings suggest that lactic acid bacteria, particularly the Lactobacillus species, dominate the microbial population in the fermentation process of nilem fish bekasam. The study highlights the significant role of LAB, especially Lactobacillus, in the fermentation process, contributing to the unique flavors, texture, and preservation properties of this traditional fermented product. This research emphasizes the importance of LAB in traditional food fermentation processes.

Mathematics learning, particularly in geometry, is often perceived as abstract and less engaging by students, leading to reduced interest and creativity. One of the geometry topics that demands a more creative and concrete approach is the tessellation of flat shapes, which emphasizes the understanding of patterns, symmetry, and regularity of shapes. The absence of contextual learning media has contributed to students’ low enthusiasm and limited ability to apply concepts in real-life contexts. This community service activity was designed to address these challenges by enhancing students’ creativity and conceptual understanding through the use of ceramic media as an innovative and enjoyable learning tool. The program was conducted at SD Negeri 1 Rowosari, Tembalang District, Semarang City, involving mathematics teachers, elementary school students, and university students. The implementation method included training and mentoring sessions. Activities encompassed the introduction of tessellation concepts, hands-on demonstrations, and the guided creation of tessellation patterns using ceramic media. Participants consisted of teachers and students who actively engaged in both theoretical and practical sessions. Evaluation was conducted through pre-test and post-test questionnaires administered before and after the training. The results revealed a significant improvement in students’ average scores after the activity. Pre-test data showed that approximately half of the students scored above the average, with two students achieving nearly perfect scores. Post-test results indicated that most students demonstrated increased understanding and creativity in applying tessellation concepts. Nevertheless, a small number of students still required further guidance, particularly in translating abstract tessellation concepts into real-life applications. Overall, the findings suggest that integrating ceramic media into mathematics learning is effective in making abstract geometry concepts more tangible, stimulating students’ creativity, and improving learning outcomes, especially in the topic of tessellation of flat shapes.

Bekasam is a traditional fermented fish product commonly produced in South Sumatra and South Kalimantan, known for its distinctive sour taste resulting from the metabolic activity of lactic acid bacteria (LAB). LAB play a crucial role in the fermentation process, contributing to the product’s flavor, texture, and safety. This study aimed to isolate, identify, and characterize LAB from bekasam made using tilapia (Oreochromis niloticus). Isolation of bacterial strains was performed using the pour plate method on Nutrient Agar (NA) medium at various serial dilutions to obtain discrete colonies. The colonies were observed macroscopically to assess their morphological characteristics, including shape, size, color, surface texture, and edge profile. Further identification involved Gram staining to determine cell wall type and microscopic morphology. The results revealed that the bacterial colonies were generally small, round, white to cream in color, with smooth surfaces and flat edges. Gram staining demonstrated that the dominant isolates were Gram-positive bacteria, exhibiting rod-shaped or oval morphology. These characteristics are consistent with members of the genus Lactobacillus sp., a common LAB group in fermented fish products. Additional phenotypic traits observed included catalase-negative reactions, absence of spore formation, and the ability to produce lactic acid as the main metabolic end product. The combination of morphological, staining, and basic biochemical characteristics supports the initial identification of the isolates as LAB. The presence of Lactobacillus sp. in bekasam suggests their significant contribution to the fermentation process, influencing the product’s sourness, safety, and preservation. The findings of this study provide a basis for further molecular characterization and potential selection of LAB strains as starter cultures to improve the quality, consistency, and safety of bekasam in traditional and industrial production.

This research aims to develop a mathematics teaching module based on differentiated learning integrated with the Project-Based Learning (PjBL) method, specifically for the topic of spatial structures ("get up room") for students at Nanasi 1 Elementary School. The development process follows the 4D model, which includes the stages of Define, Design, Develop, and Disseminate. In the Define stage, analysis revealed the absence of instructional modules that align with students' learning styles and needs. Consequently, learning objectives were formulated based on geometric elements and problem-solving criteria. During the Design stage, a prototype module and validation instruments were produced. Validation was conducted by two experts, yielding high scores for both content and visual presentation—each achieving 90% validity. Practicality assessments also showed strong results, with content rated at 90.8% and visual aspects at 90%, categorizing the module as “very valid” and “very practical.” The integration of the PjBL method was implemented to enhance active student participation, encouraging collaborative exploration and real-world application of mathematical concepts. The developed module is considered suitable for supporting differentiated mathematics instruction in elementary schools. It accommodates diverse learning styles and promotes student engagement through project-based tasks. The findings suggest that combining differentiated learning with PjBL fosters a more inclusive and effective learning environment, particularly in geometry-related topics. This module not only meets pedagogical standards but also contributes to the advancement of innovative teaching practices in primary education.

Enterobius vermicularis, or pinworm, continues to be a public health concern, particularly among children in coastal and densely populated areas. Though it is classified as a non-Soil Transmitted Helminth (non-STH), its fecal-oral transmission route allows rapid spread, especially where hygiene practices are inconsistent. In Indonesian coastal communities such as Lasiana, Kupang, limited studies have focused on the intersection between environmental factors, personal hygiene, and parental knowledge in relation to enterobiasis. This study aimed to determine the prevalence and morphological characteristics of Enterobius vermicularis in children aged 3–9 years living in the coastal area of Lasiana Beach, Kupang. A descriptive observational study was conducted involving 81 heads of households and 24 children as research participants. Data were collected through questionnaires distributed to parents to assess sanitation conditions, hygiene practices, and knowledge levels. Perianal samples were obtained from the children using the clear tape (scotch tape) method and examined microscopically to identify E. vermicularis eggs. Findings revealed that 21% of the children tested positive for E. vermicularis. The eggs displayed typical morphological features—oval shape with one flattened side and a transparent double-layered shell. Despite most respondents reporting good hygiene behavior and environmental sanitation, cases of infection persisted. Limited access to handwashing facilities and dense housing conditions were identified as contributing risk factors. The presence of Enterobius vermicularis infections despite adequate sanitation and knowledge highlights a gap between awareness and effective daily practices. These findings underscore the need for strengthened community-based health education and consistent monitoring in high-risk coastal areas to prevent enterobiasis among children.

This study aims to assess the feasibility of facilities and infrastructure at the Dok IX Flats (Rumah Susun) located in Tanjung Ria Sub-district, North Jayapura District, Jayapura City, based on the Indonesian National Standard (SNI) 03-1733-2004, as well as residents’ perceptions. The research uses a mixed methods approach, combining quantitative and qualitative methods. Data were collected through field observations and questionnaires distributed to 43 respondents using the Likert scale. The results show that, in general, the housing complex is considered feasible, with an average score of 70 or 76.1%. Facilities such as education, health, worship, green open space, road access, and drainage are considered adequate. However, inconsistencies were found in the disaster mitigation system. Although categorized as "Feasible," field observations revealed damaged evacuation routes and the absence of essential firefighting equipment (APAR). In conclusion, the Dok IX Flats are generally suitable for habitation, but urgent improvements are needed, particularly in the disaster mitigation aspect, to ensure the safety and comfort of the residents.

One of the applications of annuities in society is a credit financial instrument. In the credit system there are many risks, so this study is to compare the installment system according to the fastest and longest sample periods in credit with the ordinary annuity method system and maturity, in addition this study aims to see the movement of installments using flat interest and effective interest. The calculation results for a loan of Rp 17,915,000, within 11 months with 24% interest show the largest total interest on the flat interest type of Rp3,941,300 and the smallest total interest on the annuity interest due of Rp1,825,879. Meanwhile, the calculation of the second sample with a loan of Rp17,915,000, within 35 months with an interest of 17.32% obtained the largest total interest on the flat interest type of Rp9,050,055, with the smallest total on the effective interest type of Rp4,339,610, but only slightly different from the total interest on the annuity due of Rp4,347,542. From these results, creditors are advised to choose a credit in a period of 11 months with an annuity due, because the interest paid is much smaller than the 35-month period.

Mathematical connection ability is a crucial competence that should be developed from the elementary level, as it helps students understand the interrelationships between mathematical concepts and their applications in daily life. This study aims to analyze the mathematical connection abilities of first-grade elementary school students in learning flat shapes. The research employed a descriptive quantitative method using cognitive and psychomotor assessment instruments. The cognitive test consisted of multiple-choice and essay questions measuring students' ability to recognize, understand, classify, and apply flat shapes. The psychomotor test involved tasks such as assembling flat shapes into meaningful objects and classifying shapes by type. The results showed that students were fairly capable of identifying and grouping flat shapes, but had difficulty explaining classification reasons or relating shapes to real-life objects. The psychomotor results also indicated that fine motor skills and the ability to make real-world connections need improvement. These findings highlight the importance of contextual learning approaches and the use of concrete media to strengthen students’ mathematical connections from an early age.
