Abstract

Skema kognitif adalah teori yang digunakan untuk mengetahui perubahan atau perkembangan pengetahuan seseorang. Penelitian ini bertujuan untuk mendeskripsikan skema kognitif siswa berkemampuan matematika tinggi, sedang dan rendah dalam menyelesaikan soal cerita peluang menggunakan pendekatan Polya. Jenis penelitian ini adalah kualitatif deskriptif yang dilaksanakan di kelas IX MTs N Ngablak Magelang. Subjek berjumlah 3 siswa masing-masing 1 subjek berkemampuan matematika tinggi, sedang dan rendah. Instrumen penelitian adalah peneliti sendiri yang dibantu oleh soal tes berisi soal cerita tentang peluang dan pedoman wawancara. Skema kognitif siswa diperoleh dari hasil penyelesaian soal cerita peluang yang dipandu tahapan Polya. Hasil penelitian menunjukkan bahwa ketika membaca soal cerita, ketiga subjek mengalami disekuilibrium. Subjek yang berkemampuan matematika tinggi dan sedang mengalami proses asimilasi sebelum ekuilibrium dalam memahami masalah, merencanakan strategi penyelesaian, mengeksekusi strategi penyelesaian dan memeriksa kembali jawaban. Subjek berkemampuan matematika rendah mengalami proses asimilasi dan akomodasi sebelum ekuilibrium dalam memahami masalah, merencanakan strategi penyelesaian dan mengeksekusi strategi, tanpa memeriksa kembali jawaban. A cognitive scheme is a theory used to determine changes or developments in a person’s knowledge. The purpose of this research is to describe the cognitive scheme of students with higher, medium, and lower mathematical abilities in solving probability problems using the Polya approach. This is a descriptive qualitative research delete conducted in the 9th grade of MTs N Ngablak Magelang. Subjects in this research were 3 students who had a high, medium and low mathematical ability. The research instrument is the researchers who helped by probability question tests and interview guidelines. Students' cognitive schemes are obtained from the results of the solving probability question test guided by the Polya stage. The results showed that three subjects experienced a disequilibrium condition when reading the word problems. Subjects with high and medium mathematical abilities were experiencing an assimilation process before equilibrium in understanding problems, planning strategy, execute the strategy and checking answers. Subjects with low mathematical abilities experience assimilation and accommodation before equilibrium in understanding problems, planning resolution strategies and executing strategies, without checking the answers.

Abstract

Keterpaparan bahan bakar bensin, di antaranya karbon-monoksida (CO) dalam jangka panjang merupakan konsekuensi kerja pengemudi ojek online (ojol). Afinitas tinggi CO dengan hemoglobin (COHb) berpotensi toksik terhadap kesehatan. Risiko gangguan jiwa meliputi depresi, cemas, somatoform dan kognisi. Penelitian ini bertujuan menilai hubungan kadar CO dengan psikopatologi dan kognisi pada pengemudi ojek online. Metode penelitian ini menggunakan desain potong lintang dengan populasi target supir ojek online Jabodetabek bertempat di kampus B Universitas Trisakti Jakarta. Pengukuran gambaran psikopatologi menggunakan kuesioner SRQ-20, kognisi dengan MMSE dan COHb (kadar tinggi ³ 3,5%). Hasil menunjukkan 123 responden dengan rerata usia 37,2 tahun; gender laki-laki 80,5%; pendidikan SMA 74%; pendapatan bulanan <= Rp. 4,9 juta (94,3%). Kadar COHb laki-laki 0,8x lebih tinggi dibanding perempuan yang seluruhnya normal. Terdapat hubungan signifikan antara gender dan kadar COHb (p=0,029), dan antara kadar COHb dengan masa kerja > 5 tahun (p=0,029). Tidak terdapat hubungan signifikan antara fungsi kognitif dan kadar COHb. Gambaran psikopatologi sebanyak 26,8% namun tidak terdapat hubungan dengan kadar COHb (p=0,778). Penelitian berikutnya direkomendasikan untuk melihat faktor-faktor lain yang dapat memberi kontribusi pada psikologi dan kognitif pengemudi ojek online.

Abstract

The elderly are vulnerable to geriatric problems or syndromes, including cognitive impairment that can progress to dementia, leading to a decreased quality of life. One factor that can prevent cognitive problems or impairment in the elderly is cognitive reserve capacity, the brain's ability to optimize its function and prevent damage that can affect cognition. This study aims to analyze the relationship between cognitive reserve capacity and quality of life in the elderly. A cross-sectional study was conducted on 109 elderly in Krendang Village, West Jakarta, in February 2024. Inclusion criteria included elderly aged 60-79 years who were able to read, write, and communicate in Indonesian, were in good health or had controlled medical conditions, and were able to hear and see well. The variables studied were cognitive reserve capacity (education and employment, neuroprotection, physical health risk factors, and mental health risk factors) and quality of life, as assessed by the WHOQoL-BREF instrument. Bivariate analysis was performed using the Pearson correlation test to determine the correlation between cognitive reserve capacity and quality of life. Multivariate analysis using linear regression was performed to identify factors in cognitive reserve capacity that significantly influence quality of life. A total of 109 subjects (mean age 66.2 years with a standard deviation of 4.59) participated in this study. The mean total cognitive reserve capacity score was 41.42 ± 6.79. The mean quality of life scores for the physical domain was 14.61 ± 2.41; the psychological domain 13.08 ± 1.93; the social relationships domain 13.19 ± 2.59; and the environmental domain 14.14 ± 1.97. Sociodemographic factors significantly associated with quality of life included gender, education, family residence, and financial resources. There was a significant correlation between cognitive reserve capacity and quality of life (p<0.05), with moderate correlations in the physical domain (r=0.42) and social relationships (r=0.42), and weak correlations in the psychological domain (r=0.26) and environmental domain (r=0.26). The R2 value was 14.5%. Cognitive reserve capacity is associated with quality of life in older adults, particularly in the physical domain and social relationships.
