Abstract

Cholestrol is a physical property of natural substances in the form of fat which is useful as an essential building material for the body for the synthesis of important substances such as cell membranes and insulation materials around nerve fibers. In addition, it is useful for sex hormones, kidney children and bile acids. High cholesterol levels or hypercholesterolemia in the blood triggers hypertension. This is because high cholesterol is the cause of blockages in peripheral blood vessels that reduce blood supply to the heart. Based on these studies, it shows that the influence of obesity (overweight) and blood pressure has a role in the risk of cholesterol disease. Based on the rule view, it can be seen that the cholesterol level is 210 or it can be said that it is in the alert category, it can be seen for blood pressure 100.6 and BMI 31.8.The fuzzy mamdani method is often also known as the min-max method. Where it uses min or minimum on the implication function and max or maximum on the composition between implication functions. In its application, the madani fuzzy method uses 4 stages, namely the formation of fuzzy sets, application of implication functions, rule composition, defuzzification. This research uses a simulation method of calculating cholesterol. This research analyzes using fuzzy mamdani and matlab software assistance.

Abstract

This study investigates the acoustic differences among British, American, and Australian English accents using Praat software. A descriptive quantitative method was employed, and the data were obtained from a publicly available online source providing spoken English samples of the three accents. Two English sentences were selected and analyzed to measure acoustic features, including duration, fundamental frequency, and intensity. The analysis was conducted by segmenting each sentence in Praat and recording the acoustic measurements. The results show that British English consistently has a longer duration and higher average intensity compared to American and Australian English, indicating clearer and more emphasized speech production. In contrast, Australian English exhibits the highest average fundamental frequency across all analyzed sentences, reflecting a higher pitch level. American English demonstrates moderate values in duration, frequency, and intensity. These findings confirm that British, American, and Australian English accents display distinct acoustic characteristics even when producing the same sentences, highlighting the usefulness of acoustic analysis in identifying accent differences.

Abstract

Bahasa Inggris sebagai bahasa internasional memiliki berbagai variasi aksen yang dapat memengaruhi pemahaman dan kemampuan komunikasi pembelajar, khususnya dalam aspek pelafalan (pronunciation). Siswa sekolah dasar umumnya belum diperkenalkan pada perbedaan aksen secara sistematis, sehingga cenderung hanya mengenal satu model pengucapan. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk memperkenalkan aksen British, American, dan Australian English kepada siswa sekolah dasar melalui metode pembelajaran interaktif. Kegiatan dilaksanakan pada tanggal 13 November 2025 di SD Negeri 104242 Lubuk Pakam, Kabupaten Deli Serdang, Sumatera Utara, dengan peserta siswa kelas V dan VI. Metode pelaksanaan meliputi penyuluhan, pemutaran audio, demonstrasi pengucapan, praktik langsung, permainan edukatif, serta diskusi. Hasil kegiatan menunjukkan bahwa siswa mampu mengenali perbedaan dasar ketiga aksen, menunjukkan peningkatan minat terhadap pembelajaran bahasa Inggris, serta lebih percaya diri dalam berbicara. Secara reflektif, kegiatan ini menegaskan pentingnya pengenalan variasi aksen sejak dini untuk meningkatkan kemampuan listening, speaking, dan kesadaran fonologis siswa. Kegiatan ini direkomendasikan sebagai model pembelajaran inovatif yang dapat mendukung peningkatan kualitas pembelajaran bahasa Inggris di sekolah dasar.
