1 Cantumkan satuan penting yang digunakan. Sudah ditambahkan semuanya REVIUWER 2 (R2)
1 Kenapa penelitian ini difokuskan pada core configuration? Hal ini belum dijelaskan.
Kami telah menambahkan informasi tentang hal ini didalam manuscript intuk menjelaskan hal ini.
Sandwich panels are commonly used in civil engineering applications as walls or floors that require a large size. Meanwhile, it is extremely difficult to find a wood-based core in such a large size. As a result, small pieces of wood are connected in such a way as to form a large area as a solution. In this case, the role of configuration or layout becomes so important to be further investigated. It is therefore, the configuration of the Sengon wood core was proposed as the main parameter investigated in this research.
2 Konten tulisan sudah sesuai dengan metode yang disampaikan. Pada figure 1, keterangan SCA itu seharusnya adalah Plain (sesuai dengan tabel 1).
Yang benar adalah informasi pada gambar, long grain plain. Kami sudah merevisi informasi pada Tabel 1 menjadi long grain plain
3 Kenapa specimen kontrol tidak diambil dengan ketebalan yang sama dengan specimen yang lain dan menggunakan aluminium juga?
Sehingga bisa membandingkan dengan perlakuan yang sama.
Ketebalan total SCA, SCB dan SCC adalah 24 mm. Yang tertulis 22 mm pada Tabel 1 adalah ketebalan core nya saja. Bila ditambahkan dengan upper dan bottom skin nya yang masing-masing 1 mm, maka ketebalan total sandwich panel adalah 1+22+1 = 24 mm, sama dengan ketebalan SW sebagai control.
Kami memilih untuk membandingkan perilaku ketiga sandwich panel (SCA, SCB dan SCC) dengan solid wood (SW) karena lebih relevant. Membandingkan kemampuan sandwich panel dengan batang aluminium setebal 24 mm agak kurang kompatibel karena kekuatan aluminiumnya bisa berpuluh 1

4 Belum ada pembahasan mengenai kenapa specimen X menjadi yang terkuat dan kenapa specimen Y yang terendah kapasitasnya.
Kami telah menambahkan penjelasan berikut ini dalam manuscript:
Sandwich panels are made up of two thin skin layers separated by a thick core. The skin is designed to withstand normal and flexural loads, while the core is intended to withstand shear and compressive loads. However, because the core is quite thick, there is a portion of the core that carrying tensile and flexural loads when subjected to bending. As a result, the role of core configuration becomes extremely important in this situation as the core must be able to withstand some portion of tensile and flexural loads existed below the neutral axis. In the SCA
configuration, the solid wood core provides support through the long continuous fibers that run parallel to the loading direction. This increases the ability of SCA to withstand tensile and flexural loads over SCB and SCC.
While the SCB and SCC configurations also provide the same support, but the fibers are discontinued at certain distances along the length of wood pieces, so the load capacity is directly proportional to the length of the cut.
The load-bearing ability of solid Sengon wood (SW) is higher than that of SCC but lower than that of SCA and SCB, most likely due to the absence of the skin's role in carrying the load.
5 Masih kurangnya pembahasan mengenai behaviour SCB dan SW yang tidak konsisten.
Kami telah menambahkan penjelasan berikut ini dalam manuscript:
The presence of a glue line at the end of grain between adjacent pieces of wood causes SCB panels to appear slightly inconsistent when compared to SCA. While for SCC panels the glue lines were attached parallel to the grain which creates a better connection between the adjacent wood. In the case of SW, the inconsistency of performance under load may be attributed to the nature of wood as a biological material. One of the drawbacks of wood is that its quality varies even when it comes from the same tree. The micro- composition of a piece of wood determines how it will react when subjected to a load. All SW samples may appear similar, but they have different microstructures, which cause them to react differently under load.
6 Failure pattern of the tested sandwich panels tipe SW tidak ditampilkan
SW bukan sandwich panels, tetapi kayu Sengon utuh atau Solid Wood. Karena tema utama dari artikel ini adalah membandingkan

perilaku sandwich panel dengan konfigurasi core kayu Sengon yang berbeda, maka dalam gambar tersebut cukup ditampilkan
perbandingan pola keruntuhan ketiga tipe sandwich panel saja.
