<![CDATA[ABSTRAKPembangunan hunian dengan jenis bangunan bertingkat tinggi membutuhkan jumlah partisi dinding yang cukup banyak, dengan pasangan batu bata yang ringan dan kokoh. Pemasangan dinding bata ringan relatif lebih mudah dikerjakan ketimbang dinding bata merah biasa, namun memerlukan presisi keahlian yang tinggi. Kajian ini membandingkan nilai produktivitas pemasangan bata ringan dengan menganalisis ruang pergerakan dan kekosongan waktu pekerja menggunakan Crew Balance Chart dan Perhitungan Nilai Labour Utilization Factor (LUF), serta memberikan solusi perbaikan terhadap alur produktivitas pemasangan bata ringan berdasarkan studi kasus proyek Apartemen PT X di Kota Bandung. Pengambilan data menggunakan metode pengamatan rekaman video dan time studies. Kesimpulan yang diperoleh, ditemukan bahwa metode pemasangan bata ringan di Apartemen PT. X memerlukan perbaikan untuk meningkatkan efektivitas produksi dengan menggeser beberapa kegiatan beberapa menit lebih awal pada laden.Kata kunci: produktivitas, konstruksi, MPDM, time studies, cycle chart, crew balance chart ABSTRACTThe construction of high-rise residential buildings necessitates substantial wall partitions utilizing lightweight yet robust brick masonry. Although lightweight brick installation is more straightforward than conventional red brick masonry, it demands high precision and expertise. This study evaluates the productivity of lightweight brick installation by analyzing worker movement patterns and idle time through Crew Balance Chart analysis and Labour Utilization Factor (LUF) calculations. Based on a case study at the PT X Apartment project in Bandung City, the research proposes workflow optimization strategies for lightweight brick installation. Data acquisition was conducted through video recording observation and time studies. The findings indicate that the installation methodology requires procedural refinements to enhance production effectiveness by advancing the commencement of several activities during the laden phase. These improvements aim to minimize worker idle time and optimize crew balance, thereby increasing overall productivity in lightweight brick wall installation operations.Keywords: construction, productivity, MPDM, time studies, cycle chart, crew balance chart ]]>
