ABSTRAK LATAR BELAKANG. Memori kerja merupakan ranah kognisi yang bertanggungjawabterhadap sebagian besar masalah kognisi yang dialami seorangusia lanjut.Tujuan penelitian ini adalah untuk mengetahui manfaat mengisiSudoku terhadap fungsi memori kerja dan fungsi kognisi global usia lanjut. METODE. Desain studi adalah uji klinis tidak tersamar. Subjek merupakanwarga Panti Sosial TresnaWerda I dan III DKI Jakarta yang diambil secarakonsekutif kemudian dibagi acak menjadi dua kelompok, perlakuan dan kontrol.Kelompok perlakuan melakukan latihan Sudoku 3x/minggu selama 12 minggu.Memori kerja dinilai dengan Trail Making Test part B (TMT-B), fungsi kognisiglobal dinilai dengan Montreal Cognitive Assesment versi bahasa Indonesia(MoCA-Ina). HASIL. Terdapat 24 subjek pada kelompok perlakuan dan 27 subjek padakelompok kontrol. Terdapat 13 subjek yang memberikan kesan positif terhadaplatihan Sudoku. Penurunan waktu penyelesaian TMT-B sebesar 11,1 detik padakelompok perlakuan dan 18,8 detik pada kelompok kontrol, meskipun tidakdidapatkan perbedaan bermakna antar kedua kelompok (p = 0,816). Terdapat 8subjek (33,3%) dari kelompok perlakuan dan 11 subjek (40,7%) dari kelompokkontrol yang mengalami peningkatan nilaiMoCA-Ina (p = 0,530). KESIMPULAN. Sudoku belum terbukti dapat meningkatkan fungsi memorikerja dan fungsi kognisi global pada usia lanjut sehat, namun peningkatan fungsimemori kerja yang terlihat pada kedua kelompok menandakan adanya plastisitasneural pada usia lanjut yang bermanfaat untuk pemeliharaan fungsi kognitif. ABSTRACT BACKGROUND. Working memory deficit is responsible for most of thecognitive problem experienced by older adults.The aim of the present study was todetermine whether Sudoku training might improves these deficits and if so,whether such changes might be transferred to other cognitive domains.METHODS. This was non-blinding randomized controlled trial. Subjects wereconsecutively taken from Panti Sosial TresnaWerda I dan III DKI Jakarta afterseries of screening. All subjects were assessed with Indonesian version ofMontreal Cognitive Assessment (MoCA-Ina) for cognitive function and TrailMaking Test part B (TMT-B) for working memory. The experimental group wasgiven 12 weeks of cognitive alternate-day training based on Sudoku exercises.RESULTS. There are 24 subjects in experimental group and 27 subjects incontrol group. Nine subjects from each group showed improvement in the TMT-Bcompletion time, although this difference were not statistically significant(experimental group 11.1s Vs control group 18.8s; p = 0.816). There were 8subjects (33.3 %) on experimental group and 11 subjects (40.7 %) on controlgroup had increment in MoCA-Ina scores (p = 0.530). Thirteen subjects reportedimprovements in memory, attention and concentration span.CONCLUSIONS. The use of Sudoku as one of the cognitive training tools on elderly still need further study and discussion regarding limitation of this presentstudy. But the improvement of working memory function as seen in resultprovides potential brain plasticity for maintaining cognitive function in elderly. ;BACKGROUND.
