Penelitian scale up pada produksi greening material lumut (Sphagnum sp.) di atas atap bangunan penting sebagai persiapan skala industri komersial dengan segmen pasar pemerintah daerah, pengusaha hotel dan restoran, masyarakat daerah urban, serta komunitas pecinta lingkungan. Penelitian sebelumnya terbatas pada pilot plant scale up tahap aquaculture menggunakan metode analisis dimensional dan terbukti memiliki prinsip kesamaan geometris. Prinsip kesamaan geometris kemudian diterapkan pada scale up tahap perakitan panel sebagai kelanjutan proses aquaculture. Penelitian bertujuan untuk: 1) mengidentifikasi variabel-variabel kritis dalam model analog scale up tahap perakitan panel; 2) memperoleh hasil analisis sensitivitas perubahan geometris variabel-variabel kritis dalam model analog scale up tahap perakitan panel; 3) memperoleh rancangan pilot plant scale up tahap perakitan panel; 4) memperoleh hasil validasi pilot plant scale up tahap perakitan panel. Identifikasi variabel-variabel kritis dalam model analog scale up tahap perakitan panel terbatas pada penerapan prinsip kesamaan geometris dalam metode analisis dimensional. Analisis sensitivitas perubahan geometris variabel-variabel kritis menggunakan perhitungan angka prediksi. Validasi pilot plant scale up tahap perakitan panel menggunakan uji beda independent sample t-test. Hasil penelitian yaitu variabel-variabel kritis dalam model analog scale up tahap perakitan panel yang didentifikasi yaitu massa lumut kering (m), panjang panel (p), lebar panel (l), tebal panel (t), dan fotosintesis lumut (y). Analisis sensitivitas perubahan geometris variabel-variabel kritis yaitu ukuran panjang panel 100 cm (maka massa lumut kering 540 gram, lebar panel 70 cm, dan tebal panel 6 cm) dan ukuran panjang panel 125 cm (maka massa lumut kering 1054,688 gram, lebar panel 87,5 cm, dan tebal panel 7,5 cm). Pilot plant scale up yang telah dirancang yaitu scale up (100x70x6) cm3 dan scale down (25x17,5x1,5) cm3. Validasi pilot plant scale up menghasilkan rata-rata laju fotosintesis dan serapan CO2 perlakuan pilot plant berbeda dengan laboratorium (kontrol) yaitu laju fotosintesis dengan perbedaan 25,333 μmol/m2/s (scale up) dan 6,33333 μmol/m2/s (scale down); serta serapan CO2 dengan perbedaan 14,290 μmol/mol (scale up) dan 35,40667 μmol/mol (scale down).

The research of production scale up for moss rooftop greening material (Sphagnum sp.) is prior to commercial industry with market segments including local government, business hotels and restaurants, urban society, as well as the community of environmentalists. Previous research limited to scale up of aquaculture by designing pilot plant using dimensional analysis method based on the principle of geometric similarity. Subsequently, the principle of geometric similarity is applied to scale up of panel assembly. The research aims are: 1) To identify the critical variables in analog model of scale up of panel assembly process; 2) To derive the sensitivity analysis of critical variables geometric changing in analog model of scale up of panel assembly process; 3) To derive design of pilot plant scale up of panel assembly process; 4) To derive validation result of pilot plant scale up of panel assembly process. Identification of critical variables in analog model of scale up of panel assembly process using the principle of geometric similarity in dimensional analysis method. The sensitivity analysis of critical variables geometric changing using prediction values. Validation of pilot plant scale up using independent sample t-test. The research results shows critical variables was identified in analog model of scale up of panel assembly process were mass of dry moss (m), length of panel (l), width of panel (l), and thickness of panel (t). The sensitivity analysis of critical variables geometric changing shows by increasing length of panel 100 cm (were 540 gram mass of dry moss, 70 cm width of panel and 6 cm thickness of panel) and increasing length of panel 125 cm (were 1054,688 gram mass of dry moss, 87,5 cm width of panel and 7,5 cm thickness of panel). Pilot plant scale up were designed scale up (100x70x6) cm3 and scale down (25x17,5x1,5) cm3. Validation of pilot plant scale up results the differences beetween average of photosynthesis rate and CO2 absorption in pilot plant and laboratory scale (control). The differences of photosynthesis rate were 25,333 μmol/m2/s (scale up) and 6,33333 μmol/m2/s (scale down); CO2 absorption were 14,290 μmol/mol (scale up) and 35,40667 μmol/mol (scale down).
