Data yang digunakan dalam penelitian ini meliputi gambar rencana, Site Layout proyek, jadwal pelaksanaan, frekuensi perjalanan tenaga kerja, spesifikasi Tower Crane, serta biaya operasional Tower Crane. Terdapat 7 alternatif tata letak Tower Crane yang dioptimasi. Penjadwalan menggunakan bantuan MS Project, dan perhitungan biaya mengacu pada biaya operasional proyek. Hasil optimasi menunjukkan bahwa tata letak Tower Crane paling optimal terdapat pada alternatif 2, dengan titik koordinat X = 40.878 dan Y = 52.358, menggunakan Tower Crane tipe QTZ 100, diperoleh nilai Travelling Distance sebesar 1.361,68 dan Safety Index sebesar 881,20, dengan total waktu penggunaan Tower Crane sebesar 742,568 jam. Setelah dilakukan penjadwalan ulang, diperoleh durasi pekerjaan struktur sebesar 1.093,76 jam untuk operasional 8 jam per hari, dan 1.532,76 jam untuk operasional 12 jam per hari. dengan estimasi biaya operasional per hari sebesar Rp3.720.865,86 untuk 8 jam kerja, dan Rp3.924.632,13 untuk 12 jam kerja. Temuan ini membuktikan bahwa optimasi tata letak Tower Crane dapat memberikan dampak positif terhadap efisiensi dan efektivitas operasional proyek konstruksi dengan tingkat efisiensi 1,88%.","\u003Cp>Penempatan Tower Crane yang optimal menjadi faktor krusial dalam menunjang efisiensi waktu pelaksanaan, keselamatan kerja, serta pengendalian biaya operasional dalam proyek konstruksi berskala tinggi seperti Proyek Pembangunan Hotel Aston Inn Lumajang yang terdiri dari 2 lantai basement dan 7 lantai utama.
