Biogas is an innovation that is already known among livestock farmers. Urutsewu Village uses biogas in an effort to meet energy needs derived from cow dung, chicken dung, tofu liquid waste, and kitchen waste. The purpose of this study was to analyze the perceptions of biogas users towards the installation, economic impact, environmental impact, and social impact of biogas installation in Urutsewu Village. This research was a descriptive research with data collection conducted through direct interviews with biogas users. The source of information data was obtained from 48 respondents consisting of households that own biogas digesters and households that use non-owners of biogas digesters. The results of the study showed that 67% of biogas users knew about biogas before using it and 33% after using biogas. Respondents tended to say that biogas technology is easy to implement, easy and simple maintenance. The perception of biogas users regarding environmental impacts is that biogas technology can reduce pollution, reduce sources of disease and improve environmental quality. Biogas technology can relatively save fuel costs and is cheaper than other fuels but is not sufficient as cooking fuel. The community agrees to process waste into biogas and supports the government in biogas processing

Biogas is one of the alternative energy sources that can be updated because it uses raw materials derived from livestock manure. The research aims to analyze biogas production from a mixture of odot grass and cow manure. The study was conducted with 3 treatments namely 100% cow manure (control), 70% cow manure + 30% odot grass, and 50% cow manure + 50% odot grass. The parameters are temperature, degree of acidity, total solid and volatile solids, volume biogas, flame test, and C and N content measurement. The research design used was a Completely Randomized Design (CRD) Each treatment was repeated three times. The results showed that the mixture of cow manure biogas with odot grass was very real (P<0.05) against the production of biogas produced successive production values for M₁₀₀G₀, M₇₀G₃₀, and M₃₀G₃₀ 191.3500 mL; 99,0067 mL and 0.0000 mL. The C/N ratio of each treatment is 27.52; 25.32 and 23.85. The average daily temperature is about the same for all treatments which is 27-29°C. The pH value of each treatment is 5.90-7.27; 5.00-7.00 and 4.77-6.70. The content of TS, VS the initial and final of each treatment is the initial TS of 11,014; 11,007; and 11,195; final TS 6,960; 6,794; and 6,714; initial VS 8,838; 8,965; and 9,309; final VS of 5734; 5,728; and 5,831. Biogas flames with a mixture of odot grass (M₁₀₀G₀) dan (M₇₀G₃₀) produce blue biogas flames (M₅₀G₅₀) do not produce flames. A mixture of odot grass and cow dung as a substrate did not produce high levels of biogas, compared to the non-odot grass mixture, which produced higher biogas production

Adolescence is a developmental phase that is highly vulnerable to physiological and psychological changes, including disturbances in the menstrual cycle. Academic stress is suspected to be one of the contributing factors to menstrual irregularities among female students. The purpose of this study was to analyze the relationship between academic stress and menstrual cycle disorders in adolescents. This research employed a quantitative design with a cross-sectional approach and total sampling technique, involving 136 first-year female students. The study was conducted at STIKes RS Husada Jakarta during April–May 2025. Academic stress was measured using the 42-item Depression Anxiety Stress Scale (DASS) with a scoring range of 0–3. The results showed that 93 respondents (68.4%) experienced severe to very severe stress, and 87 respondents (64.0%) had abnormal menstrual cycles. The Chi-Square test yielded a p-value < 0.001, indicating a significant relationship between academic stress and menstrual cycle disorders. These findings emphasize that academic stress has a strong influence on adolescents’ menstrual patterns and should be a priority for educational institutions when strengthening stress management programs and psychosocial support to maintain reproductive health. In conclusion, the higher the level of academic stress, the greater the risk of menstrual cycle disturbances among adolescents.

The rapid development of Internet of Things (IoT) and cloud computing technologies has significantly transformed the way organizations manage information. Management Information Systems (MIS) are no longer limited to data recording and reporting functions but have evolved into integrated systems capable of providing real-time information to support strategic decision-making. This article aims to examine the role, benefits, and challenges of implementing Management Information Systems in the era of IoT and cloud computing. The research method employed is a literature review, drawing on relevant journals, books, and scientific publications. The results indicate that the integration of IoT and cloud computing into MIS can enhance operational efficiency, data accuracy, and system flexibility. However, several challenges remain, particularly related to data security, privacy issues, and the readiness of human resources.

Biology learning on the human excretory system topic often encounters challenges due to the abstract and complex nature of the material, thus requiring interactive digital teaching materials that can enhance students’ engagement in the learning process. This study aimed to develop an excretory system e-module based on the OIDDE learning model (Orientation, Identify, Discussion, Decision, and Engage in Behavior) and to determine its validity and practicality. This research employed a Research and Development (RD) approach using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The product was validated by subject matter, language, and media experts and was limitedly tested with one biology teacher and 30 eighth-grade students at MTsN Kota Batu. Data were collected using validation sheets and response questionnaires based on a four-point Likert scale and were analyzed descriptively using percentage calculations. The results showed validity levels of 85% from subject matter experts (valid), 90% from language experts (very valid), and 95% from media experts (very valid). The practicality test results indicated percentages of 95% from the teacher and 90% from students, both categorized as very practical. Therefore, the OIDDE-based e-module is considered valid and practical and has the potential to support more active and meaningful biology learning at the junior secondary school level.
