Abstrak. Penelitian ini dilatarbelakangi oleh rendahnya kemampuan bina diri menggosok gigi pada anak dengan hambatan down syndrome yang masih memerlukan bantuan dalam melakukan setiap tahapan menggosok gigi secara mandiri. Anak mengalami kesulitan mengikuti urutan kegiatan menggosok gigi, terdapat plak-plak hitam akibat jarangnya gosok gigi menimbulkan karies pada gigi anak. Kondisi tersebut menunjukkan perlunya pembelajaran yang konkret, bertahap, dan berulang untuk meningkatkan keterampilan menggosok gigi sebagai bagian dari Activity of Daily Living (ADL). Penelitian ini bertujuan untuk menganalisis efektivitas penerapan metode forward chaining berbasis video tutorial dalam meningkatkan keterampilan bina diri menggosok gigi pada anak dengan hambatan down syndrome. Penelitian menggunakan pendekatan kuantitatif dengan metode Single Subject Research (SSR) desain A-B-A. Subjek penelitian adalah seorang anak dengan hambatan down syndrome di SLB-C Negeri Pembina Provinsi Kalimantan Selatan. Data dikumpulkan melalui tes unjuk kerja menggunakan instrumen analisis tugas (task analysis) yang dilengkapi lembar skoring, kemudian dianalisis menggunakan analisis visual dalam kondisi dan analisis antar kondisi. Hasil penelitian menunjukkan bahwa kemampuan menggosok gigi meningkat dari mean level 46% pada fase baseline-1 (A1) menjadi 51,1% pada fase Intervensi (B), dan 52,4% pada fase baseline -2 (A2). Persentase overlap sebesar 14% antara fase A1 dan B menunjukkan adanya pengaruh intervensi terhadap peningkatan kemampuan menggosok gigi. Dengan demikian, metode forward chaining berbasis video tutorial efektif meningkatkan keterampilan bina diri menggosok gigi pada anak dengan hambatan down syndrome.

Abstract. This research is driven by the low self-care ability of children with Down syndrome in brushing their teeth, as they still need assistance in going through each step independently. These children have difficulty following the sequence of brushing activities, and there are black plaques due to infrequent brushing, which leads to tooth decay. This situation indicates the need for concrete, gradual, and repeated learning to improve toothbrushing skills as part of Activities of Daily Living (ADL). This study aims to analyze the effectiveness of applying a forward chaining method based on video tutorials in improving self-care toothbrushing skills in children with Down syndrome. The study used a quantitative approach with a Single Subject Research (SSR) method in an A-B-A design. The research subject was a child with Down syndrome at SLB-C Negeri Pembina in South Kalimantan Province. Data were collected through performance tests using task analysis instruments equipped with scoring sheets, and then analyzed using visual analysis within conditions and between conditions. The results showed that the ability to brush teeth increased from a mean level of 46% in the baseline-1 (A1) phase to 51.1% in the Intervention (B) phase, and 52.4% in the baseline-2 (A2) phase. An overlap percentage of 14% between phases A1 and B indicates that the intervention had an effect on improving tooth-brushing skills. Therefore, the video tutorial-based forward chaining method is effective in improving self-care skills for brushing teeth in children with Down syndrome.
