Journal Review: Potential of Orange Peel, Fruit, and Vegetable Waste as an Environmentally Friendly Electrolyte Source for Bio-Batteries
Get PDFThe ever-increasing demand for electrical energy demands alternative, environmentally friendly, and sustainable energy sources. Conventional batteries generally rely on synthetic chemicals that have the potential to pollute the environment. One solution that is beginning to be developed is the use of organic waste as an electrolyte source in bio-batteries. This review article discusses the potential of orange peel, fruit, and vegetable waste as a natural electrolyte containing organic acid compounds, particularly citric acid (C₆H₈O₇), as well as mineral acids that can decompose into ions in solution, thus conducting electricity. Various research results show that the acid and water content of organic waste can produce a potential difference when paired with dissimilar metal electrodes, thus generating an electric current. In addition, the pH characteristics and natural electrolyte content of the waste indicate its suitability as a substitute for hazardous chemicals in batteries. Thus, the use of orange peel, fruit, and vegetable waste has the potential to become an environmentally friendly bio-battery innovation that can support efforts to reduce dependence on conventional batteries while contributing to sustainable organic waste management.
 
Spatial Analysis in Detecting the Level of Land Suitability for Clove Plants
Get PDFPlantation crops remain a central choice for many farmers because of their promising yields, and clove is among the most valued due to its strong market demand. Despite this potential, clove cultivation frequently faces constraints, particularly sudden stem bud decline and disease susceptibility. These problems often arise from land that does not meet the crop’s ecological requirements, yet many farmers still find it difficult to obtain reliable and timely information on land suitability. Spatial data offers an effective solution because it provides rapid and up to date insights into environmental conditions without requiring farmers to visit each site. When combined with big data and smart farming technologies, spatial information becomes even more useful, since farmers can monitor climate patterns, soil temperature and soil texture more easily.This study aims to generate accurate information on land suitability for clove cultivation through spatial big data and to demonstrate the role of smart farming systems in detecting suitability levels. Using a quantitative approach, land conditions were classified into four suitability categories which include very suitable, suitable, marginal and not suitable. Landsat imagery from Sinjai Regency in 2024 identified approximately 24,566 pixels or 2,282 hectares of land used for clove cultivation. These areas were concentrated in South Sinjai, Central Sinjai, Sinjai Borong and West Sinjai. Additional land cover classes consisted of primary forest, rice fields, settlements, secondary forest, annual crops and mixed plantations. The classification results were supported by categorical accuracy testing, highlighting the need to evaluate each land use type individually to ensure the reliability of the spatial interpretation
The Relationship Between Stress Levels and Premenstrual Syndrome Incidents
Get PDFAdolescence is a formative stage marked by emotional instability and biological changes, creating a complex intersection between psychological and physiological development. In this context, premenstrual syndrome (PMS) is not merely hormonal but also a psychosomatic response to psychosocial stressors. This study examined the relationship between perceived stress and PMS among 256 female students from Madrasah Aliyah Negeri in Makassar, Indonesia. Using a quantitative cross-sectional design, data were collected with the Perceived Stress Scale (PSS-10) and the Shortened Premenstrual Assessment Form (SPAF). Statistical analysis using Chi-square and binary logistic regression revealed a strong association between PMS and stress (p = 0.000). The prevalence of PMS increased markedly with stress intensity, ranging from 6.7% among mildly stressed to 95.9% among severely stressed respondents. Stress emerged as a key predictor (AOR = 30.20 for moderate stress; AOR = 330.80 for severe stress), while adequate sleep and regular physical activity acted as protective factors. These findings suggest that adolescent stress manifests as embodied experiences influenced by educational and sociocultural expectations. In academically demanding and morally prescriptive environments, emotional distress often translates into somatic expressions. Thus, PMS may function as a covert form of communication an embodied narrative of unspoken emotional struggles. Effective management should therefore integrate stress reduction, menstrual health literacy, and emotional awareness, not only improving reproductive health but also validating adolescents’ psychosocial realities
Management of Infective Endocarditis in Infarction Stroke
Get PDFInfective endocarditis (IE) is an infection of the endocardial surface of the heart often involving the heart valves characterized by the formation of vegetations composed of bacteria, fibrin, and platelets. The incidence of IE in high-income countries is estimated at 3–10 per 100,000 person-years, with regional variations; this rate remains relatively stable, but the complexity of cases and neurological complications remain a major concern. Two authors conducted a comprehensive literature search of PubMed, Scopus, NCBI, and Cochrane CENTRAL databases from 2024 to July 2025. Studies were reviewed based on incidence of infective endocarditis in infarction stroke. Infective endocarditis remains an important cause of ischemic stroke, primarily through septic emboli originating from vegetations on the heart valves. Key risk factors include the size and mobility of the vegetation, left valve involvement (mitral or aortic), and virulent pathogens such as Staphylococcus aureus. Clinical vigilance, timely antimicrobial therapy, and careful timing of surgery are key to successful management of ischemic stroke due to I
