Gluten-free flour-based cookie products face a major challenge in producing physicochemical and sensory characteristics equivalent to wheat-based products due to the absence of gluten as a structural component. One common approach to address this issue is the addition of hydrocolloids, such as glucomannan and xanthan gum. This study aims to systematically examine the effect of the ratio of glucomannan and xanthan gum on the texture characteristics, spreadability, and sensory properties of gluten-free flour-based chocolate cookies using the Systematic Literature Review (SLR) method. The literature search process was carried out on several scientific databases using keywords related to gluten-free cookies, glucomannan, xanthan gum, texture, spreadability, and sensory properties. Selected articles were selected based on inclusion and exclusion criteria, then analyzed and synthesized narratively with reference to the PRISMA guidelines. The results of the study indicate that xanthan gum tends to increase the hardness and structural stability of cookies, but can decrease spreadability and crispiness at high concentrations. Conversely, glucomannan plays a role in enhancing softness and mouthfeel through its high water-binding capacity, although it can potentially limit spreadability if used excessively. The combination of glucomannan and xanthan gum exhibits a synergistic effect in balancing textural characteristics and enhancing sensory acceptability. In conclusion, optimizing the ratio of glucomannan to xanthan gum is a key factor in developing gluten-free chocolate cookies with optimal physicochemical and sensory characteristics.

Bullying is a form of aggressive behavior that is intentionally and repeatedly carried out, characterized by an imbalance of power between the perpetrator and the victim. This phenomenon is not limited to childhood and adolescence but may also produce long term effects that extend into adulthood, including among university students. This study aims to explore the long term impact of bullying on victims’ mental health, with a particular focus on students who have experienced bullying in the past. The study employed a descriptive qualitative method using a literature review approach. Data were obtained through a comprehensive analysis of scientific articles, national and international journals, and previous studies related to bullying and mental health. The findings show that victims of bullying face a higher risk of psychological problems, such as depression, anxiety, post traumatic stress disorder or PTSD, low self esteem, and difficulties in social interactions. These effects influence not only emotional well-being but also academic functioning, including reduced concentration, decreased learning motivation, and lower academic performance. In addition, prolonged psychological stress resulting from bullying may lead to physical problems, such as sleep disturbances and somatic complaints. Factors including limited social support, maladaptive coping strategies, and high intensity or prolonged exposure to bullying were found to intensify the negative impacts experienced by victims. Therefore, this study emphasizes the importance of comprehensive prevention and intervention efforts in higher education settings, such as the provision of accessible counseling services, the implementation of strict anti bullying policies, and the strengthening of social support systems to minimize the long-term mental health effects of bullying among university students.  

Hospitalization is a condition that requires a child to be admitted to the hospital. This situation causes children to experience anxiety, restlessness, and fear. One of the nursing interventions to reduce anxiety due to hospitalization is play therapy. A form of play therapy appropriate for preschool children is puzzle play therapy. Puzzle play therapy is an activity in which children arrange pieces of pictures or specific shapes to form a complete image. This therapy encourages children to develop patience, stimulates concentration, and provides feelings of comfort and enjoyment, thereby reducing anxiety. The method used in preparing this Final Nursing Scientific Paper was a descriptive case study with the implementation of puzzle play therapy. The respondents consisted of three children experiencing anxiety due to hospitalization. Puzzle play materials and the Facial Image Scale (FIS) were used as measurement tools. The intervention was conducted over three consecutive days, with a duration of 15 minutes per session. The results showed a decrease in anxiety levels after puzzle play therapy: respondent 1 decreased from anxiety scale 5 to scale 1, respondent 2 from scale 4 to scale 1, and respondent 3 from scale 5 to scale 1. It can be concluded that puzzle play therapy is effective in reducing anxiety due to hospitalization in preschool children with dengue hemorrhagic fever. The implementation of puzzle play therapy is expected to become a routine nursing intervention to reduce hospitalization-related anxiety in preschool children with dengue hemorrhagic fever.

Excessive smartphone use among adolescents, especially students, can develop into smartphone addiction and potentially disrupt learning concentration. At SMP Negeri 11 Jambi City, most students use smartphones for long periods for entertainment and social media until late at night, which leads to drowsiness and reduced focus during lessons. This study employed a quantitative method with a cross-sectional design. The population consisted of all seventh-grade students at SMP Negeri 11 Jambi City, totaling 352 students, with a sample of 175 respondents selected through stratified proportionate random sampling. Data were collected using the Smartphone Addiction Scale–Short Version (SAS-SV) questionnaire and a learning concentration questionnaire. Data analysis was conducted using univariate and bivariate methods with Kendall’s tau-b test. The results showed that 84% of respondents experienced smartphone addiction, while 61.7% had a good level of learning concentration. Kendall’s tau-b test indicated a significant relationship between smartphone addiction and learning concentration (p-value = 0.000; r = 0.243), showing a weak association. Higher levels of smartphone addiction were linked to decreased learning concentration. Therefore, active involvement from schools and parents is needed to guide adolescents in managing stress and boredom positively.

This research was motivated by the relatively low level of student learning activities, indicated by limited participation in asking questions, answering, and expressing opinions during the learning process. In addition, some students showed low concentration and attention to the teacher’s explanations. The learning process was still teacher-centered, which reduced student activeness and affected learning outcomes. To address this problem, teachers need to apply learning methods that encourage student participation while improving learning outcomes. One method that can be applied, particularly in social studies subjects, is the Quiz Team learning method. This study aimed to determine the effect of the Quiz Team learning method assisted by Baambozle media on student activity and learning outcomes in social studies at MTsN 6 Tulungagung. The study used a quantitative approach with a quasi-experimental design, specifically a non-equivalent control group design. Data were collected through questionnaires, tests, and documentation. Questionnaires were used to measure student learning activity, while tests were used to assess learning outcomes. The sample consisted of 32 students in the control class and 32 students in the experimental class selected through purposive sampling. The results showed that the Quiz Team method assisted by Baambozle media significantly affected students’ activity and learning outcomes, indicated by a Sig. (2-tailed) value of 0.000 < 0.05. The findings imply that this method can enhance student activity and consequently improve learning outcomes.

Acid mine drainage (AMD) is characterized by low pH and high concentrations of heavy metals such as iron (Fe) and manganese (Mn) that exceed environmental quality standards, thus requiring effective treatment to prevent environmental pollution. This study aims to evaluate the ability of a mixture of activated carbon derived from pineapple leaves mixed with coal to increase pH and reduce Fe, Mn, and Total Suspended Solids (TSS) levels in acid mine drainage at PT Alreksa Bara Mitra. The process to make activated carbon involved preparation, carbonization, and activation processes on the pineapple leaves and coal separately. The following step is to mix but pineapple leaves and coal the has been activated. The treatment was conducted using an adsorption method with variations in adsorbent mass of 4 g, 8 g, and 12 g and a contact time of 30 minutes. The parameters analyzed included pH, Fe, Mn, and TSS before and after treatment, and the results were compared with the quality standards stipulated in Minister of Environment and Forestry Regulation No. 05/2022. The results showed that the characteristics of the activated carbon mixture met the SNI 06-3730-1995 standard. Increasing the adsorbent mass contributed to the rise in pH from 5.5 to near the acceptable range of 6–9 and significantly reduced Fe, Mn, and TSS concentrations below the permitted limits.The findings indicate that the mixture of pineapple leaf- and coal-based activated carbon is an effective, economical, and environmentally friendly alternative adsorbent for acid mine drainage treatment.

This study analyzes George Orwell's novel Animal Farm as a reflection of social conflicts in the 1917 Russian Revolution using M.H. Abrams' mimetic approach. The novel functions as an allegory, with Mr. Jones representing Tsar Nicholas II, Snowball as Leon Trotsky, and Napoleon as Joseph Stalin. Through the mimetic approach, this research identifies how the rebellion, power struggles, and the corruption of revolutionary ideals are depicted in the novel, ultimately leading to dictatorship that mirrors the regime they initially rejected. Orwell highlights how the revolution's original vision of equality was ultimately betrayed by the new leaders. The findings of this study show that Animal Farm not only critiques Stalinism but also reflects broader social and political phenomena related to the concentration of power, abuse of authority, and the cyclical nature of power in history. This study supports mimetic theory by demonstrating how literature can deeply reflect historical realities, contributing to the discourse in both literature and politics, and serving as a reminder of the dangers of authoritarianism.

This study aims to analyze the communication process within the Suluk tradition in Kubu Gadang, West Payakumbuh, using Dell Hymes’ Dell Hymes Ethnography of Communication approach. This research employed a qualitative method with an ethnographic approach through observation and in-depth interviews involving five informants and one triangulator, consisting of mursyid, khalifah, and salik. The findings reveal that communication in the Suluk tradition is systematically regulated to maintain participants’ spiritual concentration during the worship process. Communication occurs through verbal forms, such as dzikir, tawajuh, and spiritual instructions delivered by the mursyid, as well as non-verbal symbols, including the use of khalwat isolation tents, tasbih, and stones as counting tools. In addition, strict norms such as limiting speech, eye contact, and social interaction function as important non-verbal communication elements. These communication patterns collectively support the spiritual objectives of Suluk, particularly in strengthening self-discipline, inner focus, and closeness to Allah.

The increasing integration of internet technology in educational institutions requires structured network governance to ensure that digital resources support academic activities effectively. Unrestricted access to online platforms often leads to non-academic usage such as online gaming and social media engagement during instructional hours, which may reduce learning concentration and degrade network performance. This research develops and evaluates a network access control simulation using a MikroTik RouterBoard RB951Ui-2HnD device. The system applies firewall filtering mechanisms, hotspot-based authentication, and bandwidth allocation strategies through Simple Queue configuration. Network segmentation is implemented to differentiate teacher and student access privileges. The study adopts a Research and Development (R&D) approach to design, configure, test, and evaluate the proposed system. Testing results indicate that the firewall configuration successfully restricts access to selected online games (Mobile Legends, Clash of Clans, Roblox) and social media platforms (YouTube, TikTok, Shopee, Instagram, Telegram). Furthermore, bandwidth management demonstrates effective traffic prioritization, ensuring more stable allocation for teacher accounts in accordance with configured maximum limits. The findings confirm that structured firewall and bandwidth policies can improve network discipline, enhance performance stability, and support a controlled digital learning environment in schools.

The development of digital technology and social media, particularly TikTok, has significantly influenced the learning behavior of elementary school students. This study aims to analyze the impact of TikTok use on the learning behavior of sixth-grade elementary school students through a Systematic Literature Review (SLR) approach. Data were collected from Google Scholar following the PRISMA guidelines, resulting in 200 initial articles, which were then selected to obtain 12 articles relevant to the Indonesian context. The synthesis results show that TikTok has a dual impact. On the positive side, TikTok increases creativity, digital skills, self-confidence, interest in learning, and provides access to interesting and interactive educational content. However, excessive use without supervision has negative effects, such as decreased discipline, concentration, and motivation to learn, the emergence of academic procrastination, and changes in behavior and language that are inappropriate. These findings confirm that the influence of TikTok is greatly affected by parental supervision, the role of teachers, digital literacy, and student self-regulation. Therefore, it is necessary to use TikTok wisely, purposefully, and in an integrated manner in educational policies so that its benefits are optimized and its risks can be minimized.

Indramayu mango is a seasonal fruit that is highly favored due to its delicious taste and high nutritional content. However, high mango production is often not supported by adequate post-harvest facilities, particularly in terms of fruit ripeness classification. Currently, mango ripeness classification is still performed manually, which tends to be subjective and inconsistent. To address this issue, this study proposes a ripeness detection system for Indramayu mangoes by integrating the TGS2602 gas sensor and the YOLOv11 algorithm based on image processing. The TGS2602 sensor is used to detect ethylene gas emitted by ripe mangoes, while YOLOv11 is employed for visual image analysis of the fruit. This study aims to evaluate the system’s performance in classifying ripe and unripe mangoes, as well as analyze the integration between the gas sensor and the object detection model. The test results show that the TGS2602 sensor can detect increased ethylene gas concentration in ripe mangoes, while YOLOv11 demonstrates high accuracy in detecting mangoes based on visual images, with precision and recall close to 1.0. The system was also tested under various lighting conditions, including dark environments, and still performed well, although with a slight decrease in accuracy under low-light conditions.

Tooth extraction is a procedure to remove a tooth from its alveolar bone socket. The causes for tooth extraction include caries, periodontitis, fractures, impacted teeth, the need for orthodontic treatment, and persistent primary teeth. Post-extraction bleeding is the most common complication that occurs. Hemostasis is a mechanism to stop bleeding from blood vessels to prevent excessive blood loss when an injury occurs, ensuring that blood continues to flow smoothly. In stopping bleeding, there are three processes involved: vasoconstriction (the narrowing of blood vessels), platelet activity, and the activity of blood clotting factors. Bleeding time is the time interval from when blood exits the blood vessel until the bleeding stops. The normal range for bleeding time is 1 to 3 minutes. Balakacida leaves contain active compounds including alkaloids, tannins, flavonoids, saponins, and phenolics. To determine the effect of Balakacida leaf extract (Chromolaena odorata) as a hemostatic agent following tooth extraction in Wistar rats (Rattus norvegicus). This study uses an experimental method with a Post-Test Only Control Group Design. The samples used in this research are male Wistar rats (Rattus norvegicus), aged 2–3 months, weighing between 200–250 grams. The research data were processed and analyzed using the One-Way ANOVA test. The results showed that treatments at concentrations of 10%, 20%, and 30% were able to significantly accelerate bleeding time compared to the control group. The administration of Balakacida leaf extract is effective as a hemostatic agent following tooth extraction in Wistar rats.  

The use of cosmetics, especially day creams, is increasing along with the high public interest in facial skin care. However, day cream products are still found to potentially contain hydroquinone, a skin whitening agent whose use is restricted because it can cause harmful side effects on skin health. This study aims to identify the presence and determine the levels of hydroquinone in day cream products circulating in District X, Sukoharjo Regency, and to assess their compliance with the regulations of the Food and Drug Monitoring Agency (BPOM). This study was a descriptive analytical study using a purposive sampling technique. A total of 15 day cream products were analyzed, consisting of 8 BPOM-registered products and 7 products not registered with BPOM. Qualitative analysis was conducted using color reaction tests with FeCl₃, Benedict’s, and o-phenanthroline reagents. Furthermore, quantitative analysis was performed using the High Performance Liquid Chromatography (HPLC) method to accurately and specifically confirm the presence and determine the levels of hydroquinone. The results showed that the color reaction test has limitations in specifically identifying hydroquinone. HPLC confirmation revealed the presence of hydroquinone in several day cream samples, with concentrations ranging from 0.024% to 0.150%. These findings indicate the need for stricter monitoring of day cream distribution to ensure the safety of cosmetic products for the wider public.
