Abstract

A simple machine is a mechanical device that can change the direction or magnitude of a force. More simply, a simple machine is a tool used to simplify work or tasks. A lever is one type of simple machine that we often encounter. This lever has three main components: a fulcrum, a load point, and a force point. The first type of lever has a fulcrum that is between the load and the applied force. The second type of lever has a load point located between the fulcrum and the force point. The third type of lever has a force point located between the fulcrum and the load. The study used a direct practical method to observe how levers 1, 2, and 3 work. This study aims to explain how levers work, compare their mechanical efficiency, and show their implementation in everyday life and in more efficient science learning. The result of this study is that we can see and differentiate between levers 1, 2, and 3, both in terms of how they are used and the types of tools that can be used. One crucial topic in science is simple machines, for example levers, which help lighten work without requiring additional energy. Levers are classified into three types based on the position of the fulcrum, load, and force, each of which has different mechanical advantages.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe make a match terhadap kemampuan penalaran matematis siswa pada materi teorema pythagoras kelas VIII SMP Negeri 4 Narmada tahun ajaran 2024/2025. Penelitian pendekatan kuantitatif ini menerapkan jenis penelitian eksperimen semu dengan desain statis dengan dua kelompok. Teknik pengambilan sampel menggunakan sampling berkelompok (cluster sampling) dimana kelas VIII A sebagai kelas eksperimen dan kelas VIII C sebagai kelas kontrol. Instrumen dalam penelitian ini adalah modul ajar, lembar observasi dan tes kemampuan penalaran matematis siswa yang telah dinyatakan valid. Pada teknik analisa data, sebelum dilakukan uji t data hasil posttest terlabih dahulu dilakukan uji normalitas dan uji homogenitas. Dari hasil penelitian dengan pengambilan data menggunakan tes kemampuan penalaran matematis diperoleh data bahwa terdapat perbedaan signifikan antara kelas eksperimen dan kelas kontrol. Dilihat dari hasil analisa data dengan uji t menunjukkan t_hitung>t_tabel. Hasil uji effect size diperoleh 0,67 berada dalam kategori sedang. Sehingga dapat disimpulkan bahwa terdapat pengaruh model pembelajaran kooperatif tipe make a match terhadap kemampuan penalaran matematis siswa pada materi teorema pythagoras di kelas VIII SMPN 4 Narmada tahun ajaran 2024/2025 pada kategori sedang.

Abstract

Soil-transmitted helminth (STH) infections remain a significant public health issue in developing countries, particularly among primary school children who are highly exposed to contaminated environments and often have inadequate personal hygiene practices. This study aimed to describe the presence of STH eggs in fecal samples of first- to third-grade students at SDN 23 Pasir Sebelah, located in Koto Tangah District, an area with historically high helminth infection rates. A descriptive cross-sectional design was used, involving total sampling of 124 students. Fecal specimens were examined microscopically using the direct smear method. Results showed that 6 students (6.9%) tested positive for STH eggs. The species identified included Ascaris lumbricoides (50%), Trichuris trichiura (40%), and hookworm (10%). Infections were more frequently found in male students and those aged 7–8 years. Most infected children demonstrated poor personal hygiene, particularly related to handwashing, nail cleanliness, and consistent use of footwear. In conclusion, the prevalence of STH infection among students at SDN 23 Pasir Sebelah was relatively low; however, inadequate personal hygiene remains a key contributing factor. Strengthening health education and promoting proper hygiene practices are essential to reduce the risk of STH transmission in school-aged children
UNEXPECTED EXTRAPYRAMIDAL REACTION: ACUTE TARDIVE DYSKINESIA FOLLOWING SHORT-TERM METOCLOPRAMIDE USE IN A PATIENT WITH DIABETES AND CHRONIC KIDNEY DISEASE Helmizar, Roland; Yuri Haiga; Vina Tri Septiana; Nana Liana; Ruhsyahadati Ajisman; Rahma Triyana; Muhammad Rizki Saputra

Abstract

Tardive dyskinesia (TD) is a potentially irreversible extrapyramidal movement disorder characterized by involuntary, repetitive movements, predominantly affecting the orofacial region. Although most commonly associated with prolonged exposure to dopamine receptor–blocking agents, TD may also arise following the use of gastrointestinal prokinetics such as metoclopramide. Female sex, diabetes mellitus, advanced age, and renal impairment are recognized risk factors that increase susceptibility, yet TD remains underrecognized outside psychiatric settings. A 49-year-old woman with poorly controlled type 2 diabetes mellitus presented with nausea, vomiting, and generalized weakness. Laboratory findings demonstrated normocytic anemia, uncontrolled hyperglycemia (HbA1c 9.2%), and acute-on-chronic kidney disease (eGFR 22 mL/min/1.73 m²). She received standard supportive therapy, including intravenous metoclopramide. Within 24 hours, she developed repetitive tongue protrusion and orofacial dyskinesia. Neuroimaging and electrolyte evaluation were unremarkable, and there was no history of prior neuroleptic exposure. Metoclopramide was promptly discontinued, leading to gradual improvement and complete resolution of symptoms within two weeks. Antiemetic therapy was switched to ondansetron. This case underscores that acute TD may occur after short-term metoclopramide use, particularly in patients with diabetes and renal dysfunction. Heightened clinical awareness and cautious prescribing are essential to prevent this potentially disabling adverse effect.
