Abstract

Health is a factor that always needs to be taken care of by each personal. Some things you can do to stay healthy are eating nutritious foods, exercising, taking care of the environment, etc. However, a person can experience health problems due to communicable diseases and non-communicable diseases. A communicable disease is a disease that can be transmitted from one person to another, directly or indirectly. One of the infectious diseases discussed some time ago in India was tomato flu. Tomato flu is an illness that results from a red rash and blisters that look like tomatoes caused by the flu. This disease is contagious in children under five years old. Tomato flu has some symptoms that are common with other infectious diseases, so people can be infected with other infectious diseases. The role of experts is necessary, but the number of experts cannot be compared with the number of victims. Therefore, an expert system is needed to diagnose these infectious diseases by the method of Forward Chaining. This method was chosen because it can diagnose infectious diseases based on a set of established data. Expert system testing is done using Black Box Testing, where each tested item generates a succesfull state.

Abstract

Penelitian ini bertujuan menganalisis penerapan model pembelajaran Problem Based Learning (PBL) dan mengidentifikasi jenis-jenis kesalahan siswa kelas IX SMP Negeri 27 Medan dalam memecahkan masalah matematis, khususnya pada materi aritmetika sosial, menggunakan Newman's Error Analysis (NEA). Model PBL dipilih karena fokusnya pada pemecahan masalah nyata untuk meningkatkan keterampilan berpikir kritis dan kolaborasi siswa. Didalam penelitian ini menggunakan metodologi deskriptif kualitatif, dengan subjek 30 siswa kelas IX-2 tahun ajaran 2025/2026, dan lima siswa dengan kesalahan terbanyak dipilih sebagai partisipan wawancara mendalam. Data diperoleh melalui observasi terbuka, tes diagnostik soal cerita, dan wawancara mendalam. Analisis data menggunakan tahapan reduksi data, penarikan kesimpulan, dan penyajian data model Miles dan Huberman. Hasil analisis NEA menunjukkan bahwa kesalahan yang paling dominan dilakukan siswa adalah Kesalahan Memahami (Comprehension Error) sebesar 25%. Hal ini diikuti oleh Kesalahan Membaca (Reading Error) sebesar 21,7%, Kesalahan Menulis Jawaban Akhir (Encoding Error) sebesar 20%, Kesalahan Keterampilan Proses (Process Skill Error) sebesar 18,3%, dan Kesalahan Transformasi (Transformation Error) sebesar 15%.

Abstract

Background: Ischemic stroke disrupts blood flow to the brain, leading to decreased motor function, particularly in the hands. Based on previous studies, a detailed and objective description of hand function at each phase of the Brunnstrom stage has not been studied. Aim(s): This study assessed hand function in post-stroke patients at Bhayangkara Tk III Banjarmasin Hospital throughout each phase of the Brunnstrom stages. Material and methods: This observational descriptive research employed a cross-sectional design. We utilized primary data through observations using the Sollerman Hand Function Test. The sample comprised 50 post-ischemic stroke patients at the Physical Rehabilitation Clinic of Bhayangkara Tk III Banjarmasin Hospital between August and October 2024, selected via purposive sampling. Result: This study indicated that 46 patients (92%) had poor hand function, while 4 (8%) had good function. The majority were in Brunnstrom phase VI (50%), followed by phase V (22%), phase III (18%), phase IV (6%), and phase II (4%). All subjects in phases II to V exhibited poor hand function. In phase VI, 4 individuals (16%) demonstrated good hand function, while 21 (84%) had poor function. Conclusions: The findings conclude that the majority of ischemic stroke patients exhibit poor hand function, highlighting the need for targeted rehabilitation strategies. Healthcare facilities should educate patients on independent motor exercises, particularly for hand function, and encourage them to follow these exercises consistently to enhance recovery.
